The thesis presented in this report has been made on behalf of Scania and their basic frame design department with the subject to solve an implementation of a weight sensing system in the chassis. The system is supposed to be implemented in the seat springs, and the reason for this is that all the force will have to go through the weight sensing transducers. With all the force going through the transducers the weight sensing system will not be sensitive for the differences in tolerances from manufacturing. The transducers could be pre-calibrated to avoid a calibration of the whole vehicle after it?s completed from the manufacturing line.Weight sensing systems is today a reality in trucks with air springs.

Powder Metal (PM) gears are machine element components which operate under the same principle as conventional gears, but, due to their intrinsic material characteristic need to be designed slightly different, and its manufacturing process offers advantages previously unobtainable by conventional steel gear manufacturing methods. The use of PM in similar applications, such as synchronous hubs, makes them a suitable candidate for production in such material. The current master thesis work focuses on gear design using PM by utilizing finite element method (FEM) to reduce weight and inertia taking into account root bending strength and tooth deflection.First a topological optimization is used to determine feasible candidates for different web designs which have as objective to reduce volume, similar topologies were shown during different loading conditions; and hence, this topology was chosen as a suitable candidate. A shape optimization of the topological candidate was performed having as state variables root bending strength, independent for compressive and tensile side of the tooth loading; and tooth deflection, which in concept can be correlated to static transmission error (TE).Another aspect in this thesis analysed is the possibility to incorporate non-trochoid root geometry, a trochoid root is always present when machining with a hob, into the gear root and hence reduce the stress concentration here. Due to the use of PM, a non-symmetric optimized root can be achieved and hence be optimizing compression and tension.Results showed significantly lower inertia, for example certain results showed 40% reduced when compared to solid gear, with adverse effects as increase in tooth deformation and increase in maximum principal stress.

Digitala läromedel blir ett vanligare inslag i skolgången då ny teknologi erbjuder tidigare okända pedagogiska möjligheter. Denna uppsats undersöker hur elever som använder ett digitalt läromedel i form av en virtuell lärmiljö för matematiklärande upplever denna lärmiljö. Dessutom undersöks elevernas prestation i lärmiljöns matematiska uppgifter. Skillnader mellan elever i olika årskurser samt elever som är matematiskt låg- eller högpresterande studeras. Matematisk prestation beskrivs utifrån Goods (1981) passivitetsmodell som innebär att lågpresterande elever är mindre risktagande i klassrumsmiljön.Elevernas upplevelse av digitala läromedel studerades i en virtuell lärmiljö bestående av två moduler, en spelmodul och en modul för skriven dialog.

En viktig del hos företag som tillverkar diverse industrimaskiner är att utbilda den personal som förväntas använda och underhålla maskinerna. Detta är för att ge användaren en god förståelse för hur maskinen i fråga fungerar och är uppbyggd. Vid sådana utbildningar är det viktigt att tillhandahålla användarvänligt utbildnings-material.Målet med detta examensarbete är att förbättra användarvänligheten för utbildningsmaterialet hos en viss utbildning för projektets uppdragsgivare. Den utbildning som skall förbättras går i dagsläget ut på att manuellt simulera processer hos en specifik maskin via en hårdvarubaserad simuleringsmiljö.Resultatet blev en lösning i form av en mjukvarubaserad simulator med tillhörande grafiskt användargränssnitt. Användaren kan därigenom på ett säkert sätt simulera maskinens beteende genom ett PC-program och då t.ex.

Fallstudie: Swedbank Syfte: Syftet med denna uppsats är att undersöka hur ett varumärke kan framställas inom tre olika kontexter. Denna studie kommer att fokuseras kring aktörerna företag och konsument inom den interna företagsmiljön samt den fysiska och virtuella tjänstemiljön.Metod: Studien utgår från en etnografisk metod, där vi studerar och deltar i olika miljöer. För att erhålla datainsamling utfördes intervjuer, observationer samt dokumentanalys. Teoretisk referensram: Vi kritiserar traditionella brand management teorier kring företagets roll vid varumärkesskapande. Vi presenterar istället brand consumptions teorierna, eftersom dessa framhäver att varumärke skapas utav fler aktörer.

ÅF Test Center in Borlänge had a need to expand their capacity for compressive and tensile strength tests. They wanted to do this by using a hydraulic cylinder, which they already possessed, to apply the force with. This required a load receiving structure. The aim of this work was to design and dimensioning a test bench for a cylinder marked NIKE 300 tons. The work would result in a completed design proposal on a test bench which could manage to run the compressive and tensile strength tests of up to 3000 kN.

In this study, we investigate various lighting applications in a virtual environment, where we compare between light based in naturalism (natural light) and pictorialism (artistic light). The purpose of this study is to gain further knowledge in lighting, which is increasingly important for game graphics. Theory are examined to gather information and recommendations on how to use various light settings that convey different emotions. We then use this information to illuminate the environment that we have built. The environment is presented in Unreal 4 for respondents who are allowed to move around freely in the environment.

The largest project at the AICG lab at Linköping University, Cognitive models for virtual characters, focuses on creating an agent architecture for intelligent, virtual characters. The goal is to create an agent that acts naturally and gives a realistic user experience. The purpose of this thesis is to develop and implement an appropriate learning model that fits the existing agent architecture using an agile project methodology. The model developed can be seen as an online unsupervised reinforcement learning model that enhances experiences through reward. The model is based on Maes model where new effects are created depending on whether the agent is fulfilling its goals or not.The model we have developed is based on constant monitoring of the system.

Oxelösund är en liten kommun på den Södermanländska kusten. Denna kommun har trots sin storlek stora problem med ohälsa i form av bland annat hög andel missbrukare. Dock kan man se att hälsoproblemen i Oxelösund är mer omfattade och innefattar i princip alla områden av folkhälsan. Man kan se att riskfaktorerna delvis är fler än friskfaktorerna. Detta kan vara en del i samhällets habitus, man en ohälsosam livsstil i Oxelösund..

In conventional viscose manufacturing, a large amount of carbondisulfide is consumed. This amount has to be decreased to keep the production cost down and to reduce the environmental impact. The purpose with this work was to show if an enzyme treatment of a dissolving pulp could increase the degree of substitution in the viscose so that the amount of carbon disulfide consumed in the process could be decreased. Previous investigations by Kvarnlöf (2007), Engström et.al. (2006) and Henriksson et.al.

I have been studied Microsoft SharePoint on behalf of Prevas in Karlstad.The purpose of my work was to see if Microsoft SharePoint was what Prevas wanted as a replacement for the existing intranet, which they are not satisfied with today.My work was a kind of foundation for Prevas so they could make a decision in this matter.The work began with installing SharePoint at one single server at Prevas. We used a virtual technology (VMware) at the installation, which can be described as that we created two ?miniservers? in a bigger server, one for SharePoint and the other for storing the information. This kind of technology is strongly advancing. The main work consisted of setting up the structure for the navigation and designing both the portal and the local homepage for Prevas Karlstad.

Most people have been forced to throw away a pot-plant after its death. There are many reasons to the death of a plant, but mainly it?s because its owner forgets it, and therefore fails to water it. The purpose of this project is therefore to develop a product which can prevent this from happening, while the product has to have a low manufacturing cost to be able to compete whit other, similar, products on the market. During the project, a benchmarking has been done to give a clear picture of what the product has to compete with. The directives there are for CE-marking, and which of these who concerns the product has also been looked up.

IntroductionIn this study, we have explained the complexities of social media, as it is still a relatively unexplored area. With the rapidly growing use of social media in recent years, companies have chosen to establish themselves in social networks to advertise themselves and communicate with their customers. In this study we analyze IKEA Sweden and their use of social media on the national market, where focus lies upon IKEA Sweden Facebook-page. The study intends to find out how the company uses social media as a marketing and communication tool and also analyzes the relations and conversations that occur on the Facebook-page. Purpose and research questionsThe purpose of the study was to gain a deeper understanding of how a large Swedish company as IKEA has chosen to use social media and how it's perceived by them. We also intended to find out how IKEA Sweden uses social media in their daily work and how the company communicates through this media channel.

This report will discuss principle, primary and finally manufacturing structure. We were asked to produce a 3D milling to processing the prototype material that is used on the University of Halmstad. From conceptual drawings to produce components for this project have we together with a number of company take developed the right components for this project. We have calculated and analyzed the construction to get the best result for it purpose. Unfortunately have the process to produce the 3D milling has been stopped because of deficient budget and time.
