    Flexibla fixturer i bearbetande maskiner2008Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [en]

    This thesis was conducted at Linköping University and Saab Aerostructures DPS, Linköping, and focuses on the possibilities of flexible fixturing in machining applications. The thesis is part of the research project "Koofix", which is collaboration between Linköping University and a number of companies.

    The thesis is aimed towards small batch production which, for Saab Aerostructures DPS, means diverse part geometry and that parts are manufactured in very small numbers, sometimes just one piece. The result of this is that expensive dedicated fixtures are made for most parts. By introducing more flexible fixturing methods to this kind of production the cost of fixtures and tooling will be reduced, and make the production more efficient.

    New flexible fixturing methods has been presented and evaluated through the thesis, which has resulted in three different concepts. These concepts have been the result of literature screening and study of current manufacturing process at Saab Aerostructures DPS. The concepts has been evaluated according to there ability to meet Saab Aerostructures DPS needs and a final concept has been chosen. The concept that is considered being the best solution employs an adjustable frame to encompass several different part geometries. This concept allows the workpiece to be machined in a single step and the fixture can be adjusted to fit workpieces with different geometries. On other concept considered in the thesis employs electromagnet with adjustable elements and is capable of fixing more complex geometries. The concept also allows the fixture to be adjusted between different products to be machine by the CNC-machine itself. Also a concept that’s not a fixture itself but a method that allows a simpler fixture to be used has been developed. This concept uses adhesives to combine extra material to the part, which allows for less complex fixtures to be used in the machining process.

    The concepts with the adjustable frame and the electromagnet and adjustable elements are both using the machines control system to locate the detail by probing before the machining process starts. Probing is done by equipping the spindle with a touch trigger probe which measures pre-programmed contact points and calculates exact part position.

    Adaptive level-of-detail representations for real-time simulation of natural environments2005Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis is written to explore the possibility of generating planet shaped virtual worlds. Today’s computer games present more and more complex worlds but have yet to show us a complete spherical world in large scale. The thesis goes in to describing a data structure sufficient for the task as well as describing how to use the structure.

    We evaluate previously done work for planar worlds and use this as a base when defining our new structure. Since a lot of work has been done in this area for planar worlds there exist several well defined concepts that can either be used as is or with a few minor changes. But certain parts needs to be replaced by new concepts since what we want to describe differs much from traditional virtual worlds. The result is a structure that enables a user to interact in real-time with a planet shaped terrain surface.

    Heteronormativitet – en begreppsanalys: ”Alla är både offer och supportrar av systemet”2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The concept heteronormativity was used in the literature for the first time in 1993. This term can be found in dictionaries and encyclopedias from 2006 but only in a few of the most modern publications. The term currently lacks an exact definition. The aim of concept analysis is to identify characteristics for a term by studying its use. Healthcare relations can and should be developed into a caring relation, which is dependent on a connection involving body, mind and soul between the caregiver and the patient. The aim of this work was to describe and deepen the understanding of the term heteronormativity from a healthcare perspective. Rodgers’ evolutionary concept analysis of 23 scientific papers and common newspapers resulted in seven defined attributes: assumptions, norms, social hierarchies, sanctions for those deviating from the norm, gender roles, sexual relationships and stereotype family apprehension. The analysis also identified what precedes the concept, two women working with the concept and five related concepts: equality, gender, power, discrimination and homophobia. A number of consequences of which all were negative for both individuals and the society were found. Healthcare is negatively influenced in several ways by heteronormativity rendering the caring relation impossible. Conclusion: Heteronormativity leads to a number of problems and everyone are both victims and supporters of the system.

    Synchronization of flywheel position between autonomous devices2012Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    More computing power will be required in Scania’s future engine control units. Calculations is therefore needed to be performed on new hardware such as an FPGA. One problem that arises is synchronization of flywheelposition. This master thesis examines the opportunities existing Scania hardware has to perform synchronization of flywheel position. Different concepts for synchronization have been developed and compared with each other. One of the concepts have been implemented and made possible witha PCB-adapter. The results show that synchronization is possible within given real-time requirements. Finally, an analysis to series production has been made. It show the challenges that an FPGA will face when integrated into a future engine control unit.

    Design of Gas Shield for Friction Stir Welding Machine2014Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The research and development of the final disposal of the nuclear waste produced by the nuclear power plants is an important work done by The Swedish Nuclear Fuel & Waste Management Co. (SKB). As the demands on a final disposal increase the laboratory equipment has to be better in order to do valid experiments. Research on how the copper canister for the spent fuel will be manufactured and handled is done at the Canister laboratory in Oskarshamn, Sweden. The work presented in this report was to design a new gas shield for the friction stir welding machine at the laboratory. The welding machine seals the canisters containing the spent fuel which are then transported to the final disposal 500 meter down in basement rock. To minimize the amount of oxide particles in the weld zone SKB have to design a better gas shield that should deliver the required atmosphere around the welding area.

    The work contains a pre study phase where the important things to consider when designing are collected. Then ideas are generated and concepts created for a new gas shield. These concepts are evaluated by a pair wise comparison method in order to find the most promising concept. The concept chosen is then detail designed to come as close to a manufacturable design as possible.

    Procedural Content Generation for a Web-Based Motion Game to Increase the Variation and Progression of the Game2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Computer games have always become more and more advanced. One of the biggest reasons to its rapid evolution is the use of procedural content generation (PCG), which is used to generate game content automatically. However, there is one type of games that is more unexplored when it comes to PCG, namely motion games. Motion games are games where the player interacts with the game by moving his own body rather than using a gamepad, mouse or keyboard. Thanks to that, motion games are a healthier alternative to regular games, and this thesis therefore explores the possibilities to use PCG to develop more exciting motion games. The focus lies on achieving variation and progression since both of those are important concepts closely related to PCG. An exploratory case study is also conducted to examine how the derived guidelines work in a real game. The result concluded is that the guidelines seem to work well, but that all of them are not easily adapted to every game. Different game genres therefore call for different guidelines to be used.

    Slöjan: om "av-slöjning": – En uppsats om unga, obeslöjade, svensk-muslimska kvinnors syn på slöjan och slöjdebatten2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This essay presents four not-/unveiled Swedish Muslim women's perceptions and experiences regarding the headscarf, the choice not to wear a headscarf, and the dominant understanding of the headscarf in Swedish society. Drawing on narratives of these women, this study aims to examine what it is that lies behind the choice not to wear the veil. Qualitative semi-structured interview was used as method for the collection of empirical data, and empirically guided thematic approach to the analysis of it. Moreover, set out from theoretical concepts of identity, classification, symbols, norms and social control, the obtained data is discussed.

    The participants in this study explains that they have never felt forced to wear the veil. They are of the opinion that one does not have to wear a headscarf in order to identify oneself as Muslim women. Islam, or ones level of religiosity, is not connected with a headscarf, rather, ones relationship as a Muslim is between that person and God. Moreover, the result indicates that the informants born in countries categorized as Muslim countries have been more affected by the Swedish secular society and its norms than those born in countries not categorized as Muslim countries. Nevertheless, they all fear potential rejection, negative sanctions and aggressions of society, causing them to stand by the decision not to wear a veil.

    Sociala investeringar som krishantering?: En studie om välfärdssamhällets förändringar med utgångspunkt i Jürgen Habermas teorier om legitimitet och kriser2015Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Uppsatsen handlar om hur välfärdsstaten förändrats sedan slutet av nittiotalet. Arbetet fokuserar på frågor om arbetsmarknad, arbetslöshet och arbets- marknadspolitik men även på hur sociala investeringar kan förstås som ett nytt sätt att se på sociala insatser. Det teoretiska ramverket utgörs av Jürgen Habermas arbeten om det senkapitalistiska samhällets framväxt, välfärdsstatens förutsättningar och begreppen legitimitet och legitimitetskriser. Uppsatsens syfte är att visa hur man med hjälp av Habermas teorier om det senkapitalistiska samhällets utveckling, legitimitet och legitimitetskriser kan förstå en välfärdsstat under press och framväxten av en aktiveringspolitik. Som en del av detta undersöks i arbetet sociala investeringar som ett socialt fenomen. Arbetet är en litteraturstudie med en teoretisk inriktning och inspiration har tagits från ett kritiskt, undersökande arbetssätt. Den viktigaste slutsatsen är att sociala investeringar kan förstås som en legitimerande insats och som en reaktion för att hantera minskad tilltro till välfärdsstaten.

    En plats för livet: En jämförande fallstudie om hur två kommuner hanterar de demografiska förändringarna2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Currently there are big differences between municipalities in Sweden. These differences leadto two dissimilar tendencies: the population is aging and the degree of urbanisation increases.The urbanisation has set several smaller municipalities in a severe economic situation and alot of municipalities are facing to either raise the local tax or reduce the public service. In thispaper the authors’ research through economic concepts how two medium sized municipalitieshave handled the demographic changes and what the municipalities should do in order toincrease their attractiveness.The findings of this study indicate that the demographic changes, to a large extent, dependson previous recessions in the municipalities which still is causing an unbalanced economy.The municipalities are facing a downward spiral that is hard to emerge from. On the otherhand some municipalities managed the recessions in a more successful way and are nowfacing a more positive economic position. Further, there is a clear correlation between a wellfunctioningintegration on the labour market and public finances. The result of the paper alsoshows that a well-functioning labour market, housing market and commercial supplydetermines municipalities’ attractiveness.

    "I am not just a domestic worker": A phenomenological study of organized Nicaraguan domestic workers in Costa Rica2015Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In this study, I use semi-structured interviews in an intersectional and phenomenological theoretical framework, elaborating on analytical concepts such as belonging and translocational positionality, to investigate the lived experiences of Nicaraguan migrant domestic workers in Costa Rica who are organized in the association Astradomes.

    I explore if and how their experiences are connected to intersections mainly between nationality, class and gender, and examine in which spaces and contexts agency and resistance can be located. I show that the intersections between nationality, class and gender - as well as age - have shaped the respondents experiences of working as domestic workers in Costa Rica, resulting in disorientation and hierarchical employer-employee relationships.  I also demonstrate that Astradomes is a social place where the social categories of the respondents, such as class, gender and nationality, produce solidarity, agency and resistance. Moreover, it is a space where the respondents have been able to relocate - and to feel at home.

    Ett miljöpolitiskt dilemma: En analys av mediedebatten kring gruvprojektet I Norra Kärr2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis aims to critically review and interpret the media debate concerning the mining project at Norra Kärr. The aim is also to bring forth and analyze the difficulties and problems that lie hidden in the arguments that outline the debate. The method used for the investigation is a contextual idea analysis. The method aims to examine the main concepts of the argument, if there are unspoken premises and investigate whether there are contradictory arguments. There is also room for an investigation of the validity of arguments. The scientific foundation and theory is based on ecological modernization, which addresses the relationship between ecology and technology and economic growth. The mining project in Norra Kärr is a very complicated and problematic matter. The debate imbued with arguments that are illogical. The major problematical issues are based in arguments that are deficient and every now and then paradoxical.

    E. Delacroix och J.M.W. Turner - Det sublimas, färgens och ljusets mästare under 1800-talets första hälft2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Between Delacroix and Turner there is sometimes a kind of kinship as displayed in some of their works, although their great differences in style. The purpose of this thesis is an attempt to capture this feeling of similarity that can be found between some of their works expressing pathos including fights for life or death against the strong forces of Nature or the evil in Man. Examples of such works are Delacroix´s Death of Sardanapalus, 1826 and Turners Slave Ship (Slavers Throwing Overboard the Dead and Dying, Thyphon Coming On),1840 and Delacroix´s The Lion Hunt, 1855 and Turners Whalers, 1845. These work express sublime greatness. Common to the works are also the highest sense for the painterly possibilities of colour. Selected works have been analysed using a contextual method regarding contents of the sublime according to esthetical theories and literary sources of the sublime in agreement with the norms for the academic painting in France and England during the first half of the 19th century. Expressions of a painterly style have been studied using a formal method including the concepts of the painterly by John Ruskin and Heinrich Wölfflin. In the formal analysis also concepts of complementary colours have been studied. The analysis shows that both artists, in several ways, have been inspired by the same esthetical concepts of the sublime and the same literary classical and romantic sources. The painterly style of both artists becomes more expressive with age and their late works hint at the modern art to come. Complementary colours, are evident in the late style of Delacroix. The kinship between Delacroix and Turner can best be summarized by Ruskins words on the sublime.

    Bäcklund transformations for minimal surfaces2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In this thesis, we study a Bäcklund transformation for minimal surfaces - surfaces with vanishing mean curvature - transforming a given minimal surface into a possible infinity of new ones.

    The transformation, also carrying with it mappings between solutions to the elliptic Liouville equation, is first derived by using geometrical concepts, and then by using algebraic methods alone - the latter we have not been able to find elsewhere. We end by exploiting the transformation in an example, transforming the catenoid into a family of new minimal surfaces.

    Myndigheters konsultanvändning: Behov, motiv och strategier2015Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Public spending on consultancy services in Sweden is today substantial and frequent. Even though such procurements are of great strategic importance for client organizations, including government agencies, there is limited research concerning strategies for clients. Therefore empirical studies are needed to shed light on the client perspective, and how the client designs its use of consultants. Against this background a qualitative research method has been conducted to gain insight of the underlying motives for using consultants, and how clients can create value by attaining a strategic exposure with consulting.

    In total 7 in-depth interviews, with an explorative design, were conducted across four government agencies with directors. The empirical study has identified a number of motives, which can be interpreted from the construction of the consultant as an expert, resource or product. The construction of the consultant as an expert refers to an asymmetric relation of knowledge in favour of the consultant. The motives that have been identified within the expert dimension are: access to expertise not profitable developing internally, access to experts that are difficult to recruit, access to industry specific knowledge, new insights and use of the consultant's impartiality. In other circumstances there is a symmetric relationship whereby the consultant is instead viewed as a resource. The motives for such usage have been identified as numerical flexibility and rapid reinforcement. Finally the purchases are sometimes motivated based on the models and concepts that the consultants sell which underline the product dimension of the consultancy services.

    The participating authorities have different views on whether consultants should, or can, be used in the core business. The study indicates that this is due to organizational differences, as well as the possibility of constructing a mix of consultants and permanent employees, working together in various projects.

    In order to deal with consultants strategically the thesis emphasize three strategic processes; legitimation, selection and control. Based on these processes it is proposed, among other things, that formal guidelines and policies are developed, that measures are taken to ensure knowledge transfer, that resources are allocated to carry out continuous market analyzes, and that framework contracts are used when possible. However, it has emerged that the procurement rules and funding structure that characterize the public sector entails a limited strategic adaptability, which may have a negative impact regarding the outcome of the use of consultants. Paradoxically the high level of bureaucracy forces the agencies to act somewhat strategically when dealing with consultants considering the rational, rule-governed, procurement process.

    Begreppskartor: En litteraturstudie om begreppskartors användbarhet för ökad begreppsförståelse i matematik2015Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I TIMSS rapport visade resultatet av matematiska tester att de flesta misstagen beror på att eleverna inte har tillräcklig begreppsförståelse eller att begreppsmodellerna inte är tillräckligt utvecklade. Resultatet visar att det är av stor vikt att eleverna skapar sig en bättre förståelse av matematiska begrepp, för att kunna få större matematisk förståelse. Vår begreppsbildning som är en process om hur vi lär oss nya begrepp eller får ytterligare kunskap om tidigare begrepp är av intresse för lärare då studier visar att vi inte har tillräcklig kunskap. Denna uppsats har fokus på hur vi kan använda begreppskartor som metod för att utveckla matematiska begrepp. Följande två frågeställningar valdes till denna studie för att undersöka metoden begreppskartor:

    1) Hur kan begreppskartor användas inom matematikundervisningen?

    2) Vilka möjligheter/svårigheter kan det finnas med att använda begreppskartor?

    I denna studie används två teorier för att beskriva begreppsutveckling: Vygotskijs inlärningsteori det sociokulturella perspektivet och Talls begreppsinlärning vilket inkluderar hans tre matematikvärldar. Detta för att ge en välgrundad teoretisk bakgrund om hur vi tillägnar oss begrepp. Då denna uppsats är en litteraturstudie utgår resultatet från tidigare forskning. Litteratursökningen skedde med hjälp av databassökning främst i databasen ERIC samt via kedjesökning. Litteraturen analyserades och ligger som grund för resultatet. Analysen visade att begreppskartor kan användas för att få en översikt av ett ämne, för att skapa ett meningsfullt lärande och undersöka vilka missuppfattningar eleverna kan ha. Begreppskartor kan användas för både inlärning och bedömning av elevernas kunskaper. För att kunna få en ökad begreppsförståelse har språket, förståelsen mellan det matematiska och svenska, en stor vikt för att kunna förstå och lösa olika matematiska problem. En av svårigheterna med att använda begreppskartor var att lärarna inte visste vad de skulle göra med elevernas kartor och att det var svårt att lära ut tekniken.

    En slutsats som kan dras utifrån dessa resultat är att begreppskartor ses som ett viktigt verktyg för begreppsbildningen framför allt för upptäcka missuppfattningar och kunna rätta till dem. Dock är språket en viktig faktor för att kunna tillgodogöra sig begrepp.

    Developing Common Questions about Integrated Product Service Engineering (IPSE), Ecodesign and Engineering Education2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In the recent years, more and more manufacturing firms recognize the benefit of providing products together with related services with an aim to gain higher profits as compared to supplying products without additional services. On the other hand, the competition in the global markets has been increased dramatically through increased sales of services in order to gain additional value for their products. In addition, several environmental challenges such as climate change, pollution, global warming impact, greenhouse gases emissions have played a vital role by influencing on the production protocols and trend of the companies. These challenges forced manufacturing countries to take into consideration environmentally conscious approach to their design thinking and industrial production processes. As a result, it became an important drive for manufacturing industries to shift from traditional product-oriented to service-oriented business models that has been witnessed during the last few years.

     

    The objective of this study research is to develop common questions that capture fundamental and common issues about Integrated Product Service Engineering (IPSE), Design for Environment (DFE) and Engineering education are effectives for industries to check and develop their knowledge, because the Engineering education plays a necessary role in associating socio-ethical knowledge with scientific and technological advances. The strategy taken to conduct this thesis task was first to study and understand the concept of Product Service System (PSS), IPSE, and Ecodesign as well as Engineering Education. Informative knowledge on these concepts were collected by reviewing several related journal articles, CIRP IPS2 conference proceedings.

     

    In this thesis the concepts of PSS, IPSE, DFE and Engineering Education discussed to develop the key common questions and issues to address the environmental, economic and social problems. Since PSS aims to reduce consumption through alternative schemes of product use as well as to increase overall resource productivity and dematerialization, but IPSE does not focus on a single factor but incorporates a wide range of factors such as environmental, social and economic issues. Whilst one of the main problems in this research focused on how to develop and strengthen the relationship between the academia and industry, and how this relation can be used to improve the academic performance and scientific research at universities and transfer them to industry.

     

    Sustainability and the life cycle concept have become a main solution for various problems such as a growing world population and a change in the industrial culture to come. As results Ecodesign and environmental considerations, financial aspects, product improvement as well as the commercial aspects were discussed in this project by understanding the previous concepts. The university considered as an important base of cultivating the talents, basic of inputs business organizations which help them to develop and improve their level of performance and quality of their products and services, and enhance its competitive position in the market. Changes in organized science further encouraged university interests in expanding technology transfer, because the scientific disciplines play an important role in influencing the type of interactions with industry as well as the University and Industry collaboration became the basic method of solving the problems to achieve (environmental, economic and social) sustainability.

    Developing a Source Criticism Learning Activity for a Digital Learning Environment in History2015Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Source criticism is an important part of the national curriculum in the history subject in middle grade schools. This master thesis presents the development of a digital learning activity for teaching students about source criticism concepts. The learning activity was developed by first researching the history curriculum and how source criticism is taught within the subject. A conceptual design was drafted based on these findings and the design of an existing framework for teaching students within the history subject. The existing framework, and the developed learning activity, is based on learning-by-teaching implemented in the form of a teachable agent. The teachable agent act as a tutee that students have to teach themselves, increasing students' motivation and learning. By teaching the agent, students improve their own learning. The final implementation of the activity is integrated into both the technical framework and the narrative of the existing environment.

    Abstract [en]

    Movement-based games are becoming more frequent in everyday lives. With easier access to webcams built into laptops and web-based games, a game which utilises both concepts can become a good option for everyday gaming.This study evaluates a movement-based game written in JavaScript using phaser.io which uses a webcam for control and HTML5 technique for capture. The main questions in the study are what observations can be done and are there any problems when developing a game with webcam-based motion-detection in regards to factors like flow, feedback and positioning. This study tries to answer these questions by building upon an existing game and implementing new functions and feedback and then observing how these effect the game-play. The results of the study showed that it is important to consider good feedback and how to position oneself when playing such a game and that more testing should be done to gain further knowledge about these two. But also that many of the implementations done made the person achieve flow while playing. Further work should be beneficial also to make the game even better while keeping it easy to play.

    Hydraulic Energy Efficiency of Concepts on an Articulated Hauler: Design and evaluation of different hydraulic concepts with focus on energy efficiency2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This master's thesis has evaluated dierent system designs for the hydraulic system on an articulated hauler at Volvo Construction Equipment (CE). The current system suers from great losses when running on low pump displacement settings. This is due to large installed displacements as a result of regulations and market demands. New system concepts have been generated and simulations in Matlab and Amesim show that some of the concepts can be implemented in order to increase energy eciency up to 65%. However, increasing eciency does in most cases also increase cost, making some of the concepts unrealistic to implement. The suggested solution for Volvo CE is to remove one pump and allow for the fan pumps to supply oil to the steering and dumping, as described in the Displacement reduction concept. They should also examine the possibility to implement clutches further.

    Regeneration in Seasonal Organizations: A Case Study of the Seasonal (re)creation of Astrid Lindgren’s World as “the same”2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background

    Explore the mystery of seasonal organizations and how they are able to (re)create themselves as “the same” after a period of dormancy.

    Aim

    To find out the organizational mechanisms that enables such (re)creation.

    Methodology

    This qualitative study was done at Astrid Lindgren’s World, a seasonal organization open from mid-May until the beginning of November. The study conducted ten interviews with both permanent and seasonal employees to find out how a year in the organization looked like to later be able to identify the seasonal mechanism.

    Findings

    This study has provided seven organizational mechanisms that are vital for Astrid Lindgren’s World to (re)create itself as “the same” from season to season.

    Concepts

    Regeneration: the process of reproducing a seasonal organization as “the same” from season to season.(Re)create: The creation of an organization that has previously been existent.“The same”: Due to individuals being subjective an organization cannot completely be (re)created as exactly the same, but rather very similar.

    Using models and representations in learning and teaching about the atom: A systematic literature review2015Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study is a systematic literature review on the role of models and representations in the teaching, learning and understanding of the atom and atomic concepts. The aim of the study is to investigate the role of different visual representations, what models and representations are used in the science classroom, how learners interpret different external representations of the atom, what mental models students construct, and how the representations can be used and designed for meaningful learning and teaching of the atom and atomic concepts.

     

    In this systematic literature review, a combination of different databases was used to search for literature, namely ERIC, Scopus and Google Scholar. Some limiters were used to narrow down the returned results: the articles should be peer-reviewed and be published 1990-01-01 or later. Ten of the returned articles were included for individual analysis in the study.

     

    The results of the study show that students often find concepts of atomic structure difficult and confusing. The abstract microscopic world of atoms cannot be seen with the naked eye, and models are therefore necessary and crucial educational tools for teaching atomic concepts in school. However, when using a model, it is important for the teacher to explain the rules of the model, and the advantages and limitations of the representation must be discussed. Analysis of the included articles revealed three types of representations used to represent atomic phenomena: two-dimensional static diagrams or pictures (e.g. a picture of the atom), three-dimensional videos or simulations (e.g. virtual reality simulations), and visual analogies (e.g. the Bohr planetary model of the atom). The use of simulations and interactive learning environments seem to have a positive effect on students’ learning. One of the studies, described in the articles included for analysis, showed that students appreciated the use of virtual reality simulations, since it made abstract concepts easier to understand when they could be visualized.

    Från herreman till sockenmålare.: En manlighetsstudie av C. J. L. Almqvists Målaren2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This essay investigates how masculinity is constructed in the short story Målaren (The painter), written by C. J. L. Almqvist. The tools used in the analysis were, first, R. W. Connells theory about there being multiple forms of masculinity represented in society simultaneously, within a hierarchical masculinity-system. Second, the concepts that were used in Sweden, in the 19th century, to describe the concept of the male, have been utilised. More specifically, the concept of a person’s character and the genre “rådgivningshandbok” have been used.      

     When analysing from a character-conceptual perspective/the perspective of a person having good or bad character, the results show that it is mostly the inner qualities, that is, in this specific text, qualities such as playfulness, imagination, and creativity, as well as good work moral, vigour, and heartiness, that are advocated. The main character, Elias, has a rich inner life, on the whole, with religious features as well.  This essay also presents a reading of Målaren which shows that the short story is a developed variant of the genre “advice manual” which was popular in the first half of the 19th century. The development consists of Almqvist seemingly having taken a step beyond/away from the condemning of those men who yielded to temptation, since he concentrates on the journey back to a virtuous life, rather than making the crime itself the main focus of the story.    

     Connell’s idea concerning a hierarchical system of masculinity has helped me with mapping the regional, Swedish, as well as the local, parish-based hegemonic masculinity which can be found in Målaren. Among other things, the analysis undertaken with Connell’s idea as support shows that the regional hegemony is strongly characterised by the system and culture of states that existed in Sweden until it was dissolved in 1866. It has also become evident that many of the characters in Målaren in spite of the fact that Elias unquestionably has a rich inner life and that the concept of a person’s character is a central aspect of the ideal masculinity, seem to be judged with respect to which social state or class they belong to. This fact indicates that the regional hegemonic masculinity permeates and affects the local, although some clashes have been demonstrated.

    Chaotic Field Exploration: Exploring systemic field dynamics in bilateral negotiations2014Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The purpose of this paper is to explore the nature of the social field as described by Pierre Bourdieu as well as to explore the possibility of creating a more focused and tailored set of conditions in the form of a model to repurpose the field theory to more clearly be applicable to bilateral negotiations.

    The methodological approach is conceptual analysis based on the epistemology of critical realism. The supporting theories for the approach are a combination of systemic, chaos and complexity theory while the fundaments for the implementation of the methodological approach are the four main concepts in Bourdieu’s theory of the social field:  the field, habitus, illusio and symbolic capital. One of the main points of repurposing this specific dynamic is to explicitly allow for deliberate human agency within the field.

    Analytical data consists purely of the secondary type. This essay is not empirically based but rather theoretical and abstract. The paper is founded on the basic principles of macrosociology and presumes social agency where appropriate.

    This paper focuses on creating a tentative framework model based on repurposed concepts derived from Bourdieu. The results are arguably interesting but are mostly limited to affecting further development of this tentative model and prefacing application of it through attempting to implement it in an analytical manner on empirical data.

    Invisible voices: understanding the sociocultural influences on adult migrantsʼ second language learning and communicative interaction2014Doctoral thesis, monograph (Other academic)
    Abstract [en]

    This dissertation is a qualitative study exploring the sociocultural influences on adult migrants’ second language learning and the communicative interaction through which they use the language. Guided by a theoretical perspective based on the concepts of life-world, habitus, social capital, symbolic honor, game, and the idea of the interrelatedness of learning and using a second language, this study aims to understand how migrants’ everyday life context, attachments to the home country, and ethnic affiliations affect the motivation for and attitude towards learning and using Swedish as a second language. Furthermore, the study explores in what way the context within which the language is taught and learned might affect the language development of adult migrants.

    The research questions of the study focus on both the institutional context, that is to say, what happened in a particular classroom where the study observations took place, and a migrant perspective based on the participants’ experiences of living in Sweden, learning the language and using it. Semi-structured interviews, informal conversational interviews, and classroom observations have been used as strategies to obtain qualitative data.

    The findings suggest that most of the participants experience feelings of non-belonging and otherness both in the classroom context and outside the classroom when they use the language. These feelings of non-belonging make the ties to other ethnic establishments stronger and lead to isolation from the majority society. The feelings of otherness, per se, are not only related to a pedagogical context that advocates monoculturalism but are also rooted in the migrants' life-world, embedded in dreams of going back to the home country, while forging a constant relation to ethnic networks, and in the practice of not using the Swedish language as frequently in the everyday life context as would be needed for their language development.

    Extracting analyzable models from multi-threaded programs2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    As technology evolves, the need to use software for critical applications increases. It is then required that this software will always behave correctly. Verification is the process of formally proving that a program is correct. Model checking is a technique used to perform verification, which has been successful with finite state concurrent programs. In the recent years, there has been progress in the area of the verification of infinite state concurrent programs. There can be several sources of infiniteness. Relevant to this thesis are recent model checking techniques developed at LiU, that can automatically establish correctness for programs manipulating variables that range over infinite domains, and spawning arbitrary many threads, which can synchronize using shared variables, barriers, semaphores etc. These techniques resulted in the tool PACMAN for the verification of multi-threaded programs.

    The aim of this thesis is to extract analyzable models from multi-threaded C programs, in order to use them for verifying the program that they describe, by using PACMAN. In addition, we augment the C programming language to allow the possibility of expressing some important concepts of multi-threaded programs, such as non-determinism, atomicity etc, with the use of the traditional C syntax.

    In a following step, we target PACMAN's input format, in order to verify our extracted models. Such verification engines usually accept as input the description of a multi-threaded program expressed in some modeling language. We, therefore, translate a minimum subset of the C programming language, which has been augmented, to effectively describe a multithreaded program, to PACMAN's input format and then pass the description to the engine.

    In the context of this thesis, we have successfully defined a set of annotation for the C programming language, in order to assist the description of multi-threaded programs. We have implemented a tool that effectively translates annotated C code into the modeling language of PACMAN. The output of the tool is later passed to the verification engine. As a result, we have contributed to the automation of verifying multi-threaded C programs.

    Executive functions and Planning in everyday life: Assistive Technologies for Cognition and their lack of support for children with Attention Deficit / Hyperactive Disorder2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The evaluation of how Assistive Technologies for Cognition (ATC) serve their purpose in providing support for children with Attention Deficit/Hyperactive Disorder (AD/HD) is limited and it is not clear how to best support the cognitive functions in order to help the individual increase task performance in everyday life. This thesis sought to scrutinise how families with at least one child diagnosed with AD/HD incorporate ATCs in their daily life in order to cope with appurtenant difficulties. An online survey, answered by 92 caregivers for children with AD/HD, attended to the cognitive abilities in need of support, the usage of ATCs, and how ATCs supported the executive functions in everyday planning. The results reveal that children encounter difficulty in dealing with cognitive ability, executive functioning and causal inference when it comes to planning in everyday life situations, which relates to lower levels of independence. Executive functioning and causal inference is negatively correlated to number of symptoms of AD/HD. The ATC is not satisfactorily supporting the cognitive functions, which results in another person by default being the one who sets up the ATC, and the child merely follows the instruction. The results has been processed into a table containing concepts which is suggested to be considered both when developing, as well as evaluating, ATCs for children with AD/HD.

    Remarkable curves in the Euclidean plane2014Independent thesis Basic level (degree of Bachelor), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [en]

    An important part of mathematics is the construction of good definitions. Some things, like planar graphs, are trivial to define, and other concepts, like compact sets, arise from putting a name on often used requirements (although the notion of compactness has changed over time to be more general). In other cases, such as in set theory, the natural definitions may yield undesired and even contradictory results, and it can be necessary to use a more complicated formalization.

       The notion of a curve falls in the latter category. While it is intuitively clear what a curve is – line segments, empty geometric shapes, and squiggles like this: – it is not immediately clear how to make a general definition of curves. Their most obvious characteristic is that they have no width, so one idea may be to view curves as what can be drawn with a thin pen. This definition, however, has the weakness that even such a line has the ability to completely fill a square, making it a bad definition of curves. Today curves are generally defined by the condition of having no width, that is, being one-dimensional, together with the conditions of being compact and connected, to avoid strange cases.

       In this thesis we investigate this definition and a few examples of curves.

    Dynamic Visualization of Space Weather Simulation Data2014Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The work described in this thesis is part of the Open Space project, a collaboration between Linköping University, NASA and the American Museum of Natural History. The long-term goal of Open Space is a multi-purpose, open-source scientific visualization software. The thesis covers the research and implementation of a pipeline for preparing and rendering volumetric data. The developed pipeline consists of three stages: A data formatting stage which takes data from various sources and prepares it for the rest of the pipeline, a pre-processing stage which builds a tree structure of of the raw data, and finally an interactive rendering stage which draws a volume using ray-casting. The pipeline is a fully working proof-of-concept for future development of Open Space, and can be used as-is to render space weather data using a combination of suitable data structures and an efficient data transfer pipeline. Many concepts and ideas from this work can be utilized in the larger-scale software project.

    Unsupervised Spatio-Temporal Activity Learning and Recognition in a Stream Processing Framework2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Learning to recognize and predict common activities, performed by objects and observed by sensors, is an important and challenging problem related both to artificial intelligence and robotics.In this thesis, the general problem of dynamic adaptive situation awareness is considered and we argue for the need for an on-line bottom-up approach.A candidate for a bottom layer is proposed, which we consider to be capable of future extensions that can bring us closer towards the goal.We present a novel approach to adaptive activity learning, where a mapping between raw data and primitive activity concepts are learned and continuously improved on-line and unsupervised. The approach takes streams of observations of objects as input and learns a probabilistic representation of both the observed spatio-temporal activities and their causal relations. The dynamics of the activities are modeled using sparse Gaussian processes and their causal relations using probabilistic graphs.The learned model supports both estimating the most likely activity and predicting the most likely future (and past) activities. Methods and ideas from a wide range of previous work are combined to provide a uniform and efficient way to handle a variety of common problems related to learning, classifying and predicting activities.The framework is evaluated both by learning activities in a simulated traffic monitoring application and by learning the flight patterns of an internally developed autonomous quadcopter system. The conclusion is that our framework is capable of learning the observed activities in real-time with good accuracy.We see this work as a step towards unsupervised learning of activities for robotic systems to adapt to new circumstances autonomously and to learn new activities on the fly that can be detected and predicted immediately.

    Trust Logics and Their Horn Fragments: Formalizing Socio-Cognitive Aspects of Trust2015Independent thesis Basic level (degree of Bachelor), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [en]

    This thesis investigates logical formalizations of Castelfranchi and Falcone's (C&F) theory of trust [9, 10, 11, 12]. The C&F theory of trust defines trust as an essentially mental notion, making the theory particularly well suited for formalizations in multi-modal logics of beliefs, goals, intentions, actions, and time.

    Three different multi-modal logical formalisms intended for multi-agent systems are compared and evaluated along two lines of inquiry. First, I propose formal definitions of key concepts of the C&F theory of trust and prove some important properties of these definitions. The proven properties are then compared to the informal characterisation of the C&F theory. Second, the logics are used to formalize a case study involving an Internet forum, and their performances in the case study constitute grounds for a comparison. The comparison indicates that an accurate modelling of time, and the interaction of time and goals in particular, is integral for formal reasoning about trust.

    Finally, I propose a Horn fragment of the logic of Herzig, Lorini, Hubner, and Vercouter [25]. The Horn fragment is shown to be too restrictive to accurately express the considered case study.

    Redesign av reduktionsutrustning i asselvalsverk inom stålindustri: Ett examensarbete utfört på konstruktionsbyrån BEKAB mot stålindustriföretaget Ovako2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The interest in seamless steel tubes with large outside diameters in relation to thin wall thickness has increased along with the strength improvements in various steel grades. This makes it possible to produce lighter, cheaper and more material-efficient steel products with the same or greater strength as before.

    These new development directions bring changes and challenges in one of the company Ovako's production lines in Tube Mill 5 Hofors, which they need to cooperate with the design agency BEKAB to evaluate and develop.

    In Ovako's production line in Tube Mill 5 there is a part of an assel mill called "förreducerare". Ovako sees a lot of interest in evaluating and developing this part of the assel mill in order to better adapt to the new development directions. A well-known challenge of the existing reduction equipment is that it was initially developed to reduce a quality issue with the tube products called funnel formation. The project therefore immerses itself into the funnel formation in order to better understand the foundations of the current design of the reduction equipment and to then implement a redesign of the reduction equipment.

    A situation analysis of the current reduction equipment reveals a number of different production issues with their accompanying quality issues in the tube products. The project thus chooses to focus on the production issues that would have the greatest impact on the reduction equipment if they were resolved. This results in a new product concept of the reduction equipment in the form of a visual 3D-CAD-model with associated strength calculations and material optimization.

    The study covers topics such as design, engineering, product development, material strength calculations and material optimization.

    A Conceptual Female Hygiene Product: Developed from Needs and Prerequisites in an Agricultural East African Context2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Menstruation is a large problem for females in development countries today. Studies have shown that around 40 percent of menstruating girls have been absent from school due to their menstruation. One of the challenges that need to be solved is the absence of female hygiene products amongst women, especially in low income and developing countries due to the cost of commercial products. In countries where the national economy is unstable or poorly comes a problem with importing products, it would be better if they could produce their own products so that the national economy is supported. Small factories and production sites that produce female hygiene products have started to form in some areas. This shows that it is possible to produce in the context where the product is going to be sold. One of the advantages of this system is from the environmental perspective, many of the local production sites use environmentally friendly materials and some products are up to 95 percent bio-degradable. The purpose of this thesis is to develop a concept for a sustainable female hygiene product that women in developing countries can afford to buy, this so that social effects can be enabled due to the security that a functioning protection can bring. To be able to do so a field study in Uganda has been conducted. During the study users and local producers were interviewed to find out what demands and prerequisites there are to create a female hygiene product that can be produced and used locally. The field study gave a deeper understanding and knowledge about both the subject as whole and the technical aspects to take into consideration when developing a female hygiene product. The study confirmed that female hygiene products, or rather the lack of them, are a big problem that needs to be solved quickly. It also revealed that the possibilities for producing in the context existed but was not developed enough. Through an analysis of the empirical findings as well as theories about, for example, material and production, six concepts were developed. The concepts and already existing products were evaluated and correlated to requirements collected in the field study. One concept was chosen for further development from this evaluation. This concept consists of a disposable napkin that is fastened by putting it in holders sewn in the panty. The panty can be bought as a product with existing holders or the holders can be sewn into the users own panties. The final concept has taken both technical aspects and social effects into account. Lists of requirements on material for the concept as well as the production of it are also included in the work. A prototype of the concept has been sewn and tested. The final concept in this work is not a finished product and needs further developing before being released as a product. More work need to be done on specifying the production and specific materials to implement the concept. For further developing, it is also important to have in mind in what context the product would be used due to the different possibilities and demands that the setting gives.

    New Style in Sitcom: exploring genre terms of contemporary American comedy TV series through their utilization of documentary style2014Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Through exploring the use of documentary style in a selection of contemporary American comedy series, this thesis closes in on the question whether texts that stylistically differ from traditional sitcom can still be regarded as part of the sitcom genre. The contemporary American TV series that are being analyzed are The Office, Arrested Development, Modern Family, Parks and Recreation, Brooklyn Nine-Nine and The Michael J. Fox Show. As the series’ place within sitcom becomes apparent, the analysis ultimately leads to a critical investigation of the term “comedy verite.” Questioning the concepts applicability for the American series and their development leads to the investigation of new definitions. This analysis of contemporary televisual styles reveals a myriad of deeper issues and elucidates how stylistic developments point towards broader developments of the TV medium – towards a medium more and more defined by, or even drenched in, “reality.”

    Abstract [en]

    The purpose of the study is to do research on how selected individuals from civil society in Namibia, working with human rights or democracy, see gender equality in a Namibian context and how they regard their own role in the implementation of the Convention on the Elimination of All Forms of Discrimination Against Women. Interviews have been carried out and grounded theory has been used to analyse the data. Theoretical concepts such as gender equality, civil society and globalization have been used to support the analysis along with theories regarding implementation. Three categories are being presented in the analysis, Theory equality, Distribution of responsibilities, and Male-streaming. The conclusion of the thesis is that the work that is carried out to implement gender equality is not enough.

The thesis aims to explore the becomings of Andrea in connection with cosmetic body modifications and her experiences in relation to this of fitting and misfitting, which are related to the dis/ability system. The aim of this thesis has also been to situate her as an embodied female subject in an intersectional context, in addition to her own experiences, as multiple social categorizations intra-act in the creation of dis/ability. The thesis takes its point of departure in Rosi Braidotti’s theorization of nomadic subjectivity and employs her notion of subjectivity as a negotiation between desire and power, with the goal of analysing the affirmative potential of cosmetic body modifications, as well as being critical towards them and their effects. Rosemarie Garland-Thomson’s concepts of fitting/misfitting are used in order to analyse the intra-actions between body and environment as well as how cosmetic body modifications affect the fit and/or misfit of Andrea.  Sara Ahmed’s notion of orientation has been employed in relation to this, with the aim of showing how beauty, whiteness, femininity, and economic wealth are produced and sustained. In the thesis it is analysed how Andrea, in complex ways desires molarity at the same time as she actively resists “fixed” positionings of her. Andrea contributes to a deconstruction of the fixity of molar identity as her resistance disrupts the flow of expected behaviors - something which creates moments of imperceptibility. The thesis furthermore argues that Andrea uses cosmetic body modifications as an affirmative deconstruction of power in addition to it being a force that drives her towards the desired molarity.

    Enhancing trust online A cross Bsectional study on users judgments of online bank websites in Germany2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background: One the latest developments in the banking sector are online banks, which provide their services only online while physical offices are not available. Market research conducted in Germany, have shown that Germans are hesitating to adopt to the digital offered banking services. The major barrier for adoption is due to trust issues, which are rooted in perceived security and privacy protections. Earlier literature has found that other website interaction factors are also playing a role in order to enhance the trustworthiness of a website. Trust is a necessity in every economic and social relationship, since all relationships involve a possibility that one of the actors behaves opportunistically, and takes advantage of the other actor. The chance of opportunistic behavior contributes to the level of judged risk in the specific relationship, and together with trust ultimately affects the adoption of online banks. In order for users to become consumers of an online bank, they need to judge the online bank website as trustworthy. These judgments can be done either intuitively or throughout reasoning, considering information. The marketing field is emphasizing that intuitive judgments are essential in order to attract new consumer. However, the psychology field is stressing that even though most individuals tend to rely on intuitive judgments, these can be wrong since they can be based on heuristics and include biases.

    Purpose: In order to understand the formation of judgments by users of an online bank website, the purpose of our thesis is twofold. First, to measure the relationships between the website interaction factors and the concepts trust and risk. Second, with a lower degree of ambition, the purpose is to measure the relationship between intuitive and reasoned trust judgments.

    Methodology: The study was conducted through a quantitative research method. A six-point scale questionnaire was used in order to examine the relationships between trust, risk and the website interaction factors. A web-based questionnaire was sent out to German web users, where in total 122 respondents responded. The sample was equally split into online bank consumers and non-consumers. The statistical analysis of the data revealed results enabling to fulfill the purpose.

    Results: The findings of our thesis demonstrate that online bank consumers and non-consumers do not significantly differ in their judgments regarding the websites. The perceptions of the information quality, security and privacy protection are found as the most influential website interaction factors towards the trust judgments. Privacy and security protection are mostly influence website users in their risk judgment. Our study further reveals that online bank website users make their trust judgments through the first impression while further considerations of the websites' content enhance their trust judgments.

    Simulation and evaluation of an articulated forklift truck2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Today’s demand on forklift trucks performance and efficiency is high. The productivity is important but also the experience while handling the forklift. The handling has to be simple and genuine to make the driver feel confident and safe. To achieve high performance steering in articulated trucks, a hydraulic power system is often used.Simulation software are a powerful tool in development processes. The program gives the industry a possibility to develop, analyze and evaluate constructions and models more efficient.The purpose of this master thesis is to identify and increase the knowledge about the main challenges in the hydraulic steering system in an articulated forklift. The hydraulic system has been modelled in the simulation software Hopsan and validated against data from measurements performed on the forklift. The different challenges have been identified based on tests and the simulation results. For a deeper understanding of the system a literature study, mainly about the key components, has been done during the master thesis. A number of suggestions for improvement have been developed with focus on increasing the steering performance. The concepts and ideas have been evaluated and tested in the simulation model.The project resulted in a validated simulation model of the articulation and a number of suggested improvements on the hydraulic steering system.

    Structuring Lean Thinking in the Radio Access Network Area2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Customer’ demands, higher quality, faster and safer deliveries are some reasons for unexpected changes in the organizations. It has incremented complexity and cost. Lean production is known as a methodology to make improvements in manufacturing areas such as mentioned above and it is focused on the process of a product. But, Lean Thinking is a management strategy to make improvements in the process of a product or service and it is based on five principles. It allows having the process close to the customer eliminates tasks that do not add value and produces with low costs and high quality. However, there are some concepts ambiguous to be applied effectively to the Radio Access Network area in wireless telecom industry as a service company. Radio Access Network area transmits Radio frequency (RF) signals from the Radio Base Station (RBS) to the user equipment (UE) or mobile phone and is an area to present dynamic changes by high technology innovation. Therefore, the aim of this study is to identify improvements through for the Radio Access Network area.

    This thesis was structured to know how the five Lean principles and Lean tools can be used in the Radio Access Network area and the benefits that it could have. The study was realized through a qualitative research and five semi-structured interviews. A manager, team leaders and engineers of wireless telecom industry vendor and operators were the participants for this study.

    The results of major impact for Lean principles and Lean tools were VSM and Flow principles and Waste as Lean tool found for the Radio Access Network area. Project definition, resource planning and VOC were some improvements revealed for VSM principle. Furthermore, faster and optimal tools, training for engineers, knowledge in software and employee empowerment were some improvements found for Flow principle. Waste Lean tool showed some improvements found on customer’s focus, clear communication and waiting time reduction. Cross functional teams were other aspects that provided quality performance in the projects.

    This study seemingly is a good start for making decisions and for the high technology innovation and dynamic changes for telecom service companies.

    The preschool teacher, gender pedagogy and change: Rethinking the preschool teacher and her work for change from the perspective of sexual difference theory.2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In this thesis I aim to investigate the Swedish preschool teacher interested in change and her work, here conceptualised as gender pedagogy. I will take my departure in sexual difference theory to contrast some of the assumptions behind preschool work, gender pedagogy and gender equality. I am also reflecting upon the concepts of normalisation, freedom and change and their relevance for preschool work. To help me with this endeavour I have interviewed five preschool teachers about their work and their interest for change. The thesis is divided into three chapters mirroring the themes of the interviews. In the first chapter I reflect upon normalisation as a process inherent to preschool work, both historically and in the present, connected to notions of class, cognitive ability and sexual difference. Through the statements of my informants and theoretical discussion the concept of normalisation is nuanced and understood as a process inherent to the whole of society as well as the preschool but also as a practice that might not be possible to abolish in its entirety. In the second chapter I move my focus towards gender pedagogy. An outline of different strands of, and discussions on, gender pedagogy is given as well as a critical discussion on the aim to go beyond gender in gender pedagogy and feminist theory. As an alternative and additional approach I suggest sexual difference theory as a possible source of inspiration for gender pedagogy. In the second part of this chapter the preschool teachers express their views on, and their work with gender pedagogy. This allows for a more entangled and process oriented understanding of gender pedagogy and its different strands. I conclude this chapter by stating that gender pedagogy could be understood in terms of normalisation and even as reinforcing the masculine norm, however the process oriented understanding of change as highlighted by my informants, as well as the use of multiple strategies, theories and methods, might allow for a practice where difference instead of likeness serves as a condition for the gender pedagogical work. In the last chapter I turn to the preschool teacher as such and her history entangled with notions of femininity, motherhood and gender equality. Employing the strategy of “working through” as described by Braidotti I lay bare how the position of the preschool teacher  and her work has been represented as stereotyped woman’s work and thus connected to less worth, but simultaneously how the actual work of the preschool teachers strongly denounce this view of  woman’s work, as well as motherhood and femininity. I also show how the work of preschool teachers put into question such prominent binary pairs as mind/body, emotion/intellect, practice/theory and adult/child. I conclude that the misrepresentation of woman’s work also has material consequences in terms of working conditions for preschool teachers. To conclude the whole thesis I emphasise how the view of the female preschool teacher and the view of the child cannot be radically separated and therefore the importance of considering both adults and children in the gender pedagogy work. I also conclude that what gender equality or gender pedagogy is, is not settled ones and for all, but rather the importance to fill these concepts with a positive view of difference.

    Komponentavskrivning – ett skenproblem?: En studie av de redovisningsmässiga effekterna2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Problem: From January 2014 it is obligatory for K3-reporting companies to make component depreciation on its fixed assets. The arguments surrounding the component depreciation differs greatly and the question is whether the lack of guidance in the transition leads to a difference in application and accounting.

    Purpose: The purpose of this thesis has a descriptive and normative form of which the descriptive purpose aims to create an image of actual accounting situations and then set them against the normative theory.

    Framework: The framework consists of a general reference framework in which we describe the basic concepts related to depreciation and the economic impact of the methods. In the theoretical framework we begin with presenting general accounting theory and in more detail about the normative theory.

    Method: The study consists of a qualitative approach with semi-structured interviews. Simulations have been used to make comparisons between a real company and two fictitious corporations.

    Empirical data: The empirical data are drawn from interviews with two representatives from a real estate company that owns investment properties and materials in form of financial statements and the company´s depreciation schedules over its components.

    Conclusion: Different useful lives have been shown lead to significant differences in the accounts. However should the freedom of choice and thereby the disparities be reduced under the influences from the normative theory.

    "Alla kära feminister": En diskursteoretisk analys av de feministiska antologierna Det heter feminism och F-ordet.2014Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis is a discourse theory analysis of two feminist anthologies - Det heter feminism! and F- ordet.  By analyzing these texts through the three categories feminism & feminists, gender equality & equality and sex/gender & sexuality I have raised questions about the feminist debate in Sweden in the 21st century.

    The discourse theory’s ideas of descriptions of reality and fixation of meaning lies as a foundation for this thesis. The concepts of social constructionism, post structuralism and essentialism/anti essentialism are central for the analysis as well as concepts connected to the three previously mentioned categories.

    The intention of this thesis is to describe and analyze a fraction of the Swedish feminist debate in the 21st century and discuss its meaning in a societal context. A number of conclusions were reached in the final discussion. The differences between today’s feminist movement and the 1970’s feminist movement are connected to thoughts on a practical and a theoretical movement. It is shown how paradoxes, formed by norms and power structures in society, create a void where some people are forced to exist. Critical voices from within the movement are high lighted and connections between the feminist movement and discourse theory are established.

    Design and Manufacturing of Pneumatic Test Stand for Rod-less Cylinder vertical application2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Within LiU Fluid laboratory there had been a number of hydraulic and pneumatic test stands for research projects and teaching. The effort was needed to do more extension within the field of pneumatics. This thesis was about designing, manufacturing, building and testing the Test Stand for vertical application of pneumatic rodless cylinder. It consisted of three main parts; mechanical structure, pneumatic system and electrical and electronics. The design part focused more on the mechanical structure and pneumatic system. Electrical and electronics had to be installed to facilitate actuation and control of the system after mechanical and pneumatic components were assembled together. The mechanical structure consisted of three main parts; cabinet, carriage and ball balancer. For each part three concepts were generated, evaluated and selected to obtain the most promising concept for further development. The design values were given such that the mechanical structure should have total weight not exceeding 500 kg. The pneumatic system would supply maximum pressure of 8 bar. Upstream pressure was considered to be 6 bar after 25% pressure drop assumed to occur in the system. The mass to be lifted was typically 26 kg moving at a maximum speed of 2 m/s. The whole design process was carried out with safety and design for assembly in mind. The methodologies applied in the design included; identification of need, concept generation, concept selection, CAD modeling and simulation and FE Analysis. Development of concepts involved CAD drawings (3D and 2D) in CATIA V5, calculations and selection of appropriate materials for each component. The pneumatic cylinder applied in this design was a rod-less cylinder (Bosch Rexroth; RTC-DA, MNR: R480628571) with a Piston diameter of 50 mm, stroke of 1.2 m and cushioning stroke of 20 mm. More design information on RTC-DA was not available therefore the information in appendix A was based on series RTC-BV which had close similarities with series RTC-DA. The carriage that moves up and down along the cylinder stroke was designed with a mechanism that imparted disturbance to the system. The mechanism could be set to impart either 100.7 N or 151.02 N disturbance. The design was done with the assumptions that:

     Spring force Fs and extension x were constant

     The system had sonic flow characteristics and critical flow appeared in meter out orifice.

     The air was perfect gas which obeyed equation of state

     Specific heat was constant

     Viscosity was constant

     Flow was one dimensional

     System pressure drop was 25% of the maximum supply pressure.

    Dynamics of the system were estimated analytically and by means of simulation. Corresponding parameter values such as pressure, velocity, flow rate, cushioning stiffness, cushioning force and acceleration were obtained and compared. The product in general conformed to the specifications made prior to the design process.

    Konsten och den helige Antonius frestelse: En hagiografisk och ikonografisk studie2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis explores the legend of Saint Anthony and his temptations, and the impression his hagiography has left on the visual arts. An iconographic method is employed to investigate literature connected to the origin and later evolution of the story, which is used to classify motifs and concepts subsequently translated into painting. Via analysis of nine different depictions of Anthony, a chronological sequence is formed which lists the transformation these portrayals have undergone since the 16th century.

    A Cloud Based Platform for Big Data Science2014Independent thesis Advanced level (degree of Master (Two Years)), 30 credits / 45 HE creditsStudent thesis
    Abstract [en]

    With the advent of cloud computing, resizable scalable infrastructures for data processing is now available to everyone. Software platforms and frameworks that support data intensive distributed applications such as Amazon Web Services and Apache Hadoop enable users to the necessary tools and infrastructure to work with thousands of scalable computers and process terabytes of data. However writing scalable applications that are run on top of these distributed frameworks is still a demanding and challenging task. The thesis aimed to advance the core scientific and technological means of managing, analyzing, visualizing, and extracting useful information from large data sets, collectively known as “big data”. The term “big-data” in this thesis refers to large, diverse, complex, longitudinal and/or distributed data sets generated from instruments, sensors, internet transactions, email, social networks, twitter streams, and/or all digital sources available today and in the future. We introduced architectures and concepts for implementing a cloud-based infrastructure for analyzing large volume of semi-structured and unstructured data. We built and evaluated an application prototype for collecting, organizing, processing, visualizing and analyzing data from the retail industry gathered from indoor navigation systems and social networks (Twitter, Facebook etc). Our finding was that developing large scale data analysis platform is often quite complex when there is an expectation that the processed data will grow continuously in future. The architecture varies depend on requirements. If we want to make a data warehouse and analyze the data afterwards (batch processing) the best choices will be Hadoop clusters and Pig or Hive. This architecture has been proven in Facebook and Yahoo for years. On the other hand, if the application involves real-time data analytics then the recommendation will be Hadoop clusters with Storm which has been successfully used in Twitter. After evaluating the developed prototype we introduced a new architecture which will be able to handle large scale batch and real-time data. We also proposed an upgrade of the existing prototype to handle real-time indoor navigation data.

    MoSync för multi-plattformsutveckling till smartphones2014Independent thesis Basic level (university diploma), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [en]

    This is a thesis that is done on behalf of Meal Planning Concepts AB. The goal was to developa native multi-platform application for smartphones and tablets that would work on Android and iOS, and share database with their current web system. The functionality would be based on that found on their website. The application was developed in MoSync which is a framework that is capable of multiplatform development. The purpose with the thesis was also to evaluate MoSync during the project and present other similar tools and how they behave compared to MoSync. The report showcases the work and problems encountered during the development of the application as well as the end result. The pilot study showed that there were many othertools that focused on support for multiple platforms. Frameworks raised were jQuery Mobile, PhoneGap and Marmalade where the latter was the tool that was the most similar to MoSync. MoSync proved to be a framework in which all the company's requirements for functionality could be met except for a design simplification. Some drawbacks were that it was slightly buggy and that the community was small.
