This thesis was carried out at Atlas Copco Tools and Assembly Systems. The purpose hasbeen to develop a design tool to be used for development of new electric motors for AtlasCopcos electric nutrunners. The focus of the thesis has been to increase productivity bydecreasing the power losses in an electric tool. The productivity is defined as themaximum number of tightenings a nutrunner can perform without becoming too hot.Before starting the development of this design tool an existing Matlab script, whichcalculates the losses in a slotless electric motor, has been studied and modified torepresent the real losses in a better way. The modification has been made by performingpractical studies of different losses and then adjusting existing parameters in the Matlabscript.Because design changes in one part of a mechatronic system can lead to a decrease inperformance of another part the choice of parameters that can be changed has been madeso that other parts of the system is affected as little as possible.A study of the existing tools efficiency during an entire tightening has been made toincrease the understanding of when and where the different losses appear and to comparethe modified Matlab script with the measured values.The design tool was formed so that it executes the Matlab script, that calculates thelosses, for a number of different design options and stores the alternative which producesthe least losses.

Tailor Store är ett företag som säljer måttbeställda plagg på nätet. De har skjortor, pikétröjor, chinos, shorts, kalsonger, strumpor och accessoarer i sortimentet. Under hösten 2011 ska sortimentet utökas med kavajer och kostymer. De har tillsammans med sin fabrik tagit fram några prover på en kavaj. De proverna blev Tailor Store inte riktigt nöjda med och ville därför att jag skulle konstruera och gradera ett mönster som de skulle kunna använda i sin kommande produktion av herrkavajer.

Values, where an organization describes the attitude its members should have towards their work, are being used to a larger extent than before. The neoinstitutional theory describes organizations? attempts to create legitimacy through activities that are not really connected to their core activities. On the basis of the aforementioned theory this study examines to what extent employees and store managers at Clas Ohlson use and relate to the values of the organization in their everyday work. The study covers these individuals awareness of the impact of values in their work as well as the way they relate to values.

Under det senaste decenniet har den svenska elektronikhandeln präglats av en allt hårdare konkurrenssituation och lägre lönsamhet. Det har lett till att stora butikskedjor gått i konkurs. För att vända trenden måste företagen hanterar sina butiksverksamheter effektivt. Det blir därmed avgörande hur butikschefen sköter butiken. Av den anledningen är det intressant att underso?ka butikschefers arbetssätt för att se vad som leder till hög lönsamhet.

A debate on environmental issues and food safety has been ongoing in Sweden and it is suggested that consumers' are seeking local produce instead of global and exotic foods. Moreover, studies show that the consumers? positive attitude towards local produce does not reflect their actions. The purpose with this thesis is to contribute to a better understanding of the dissonance between the consumer?s attitudes and actual behaviour towards local produce.

Multiple factors are involved in control of beef sensory quality so great variation can be induced. The perception of meat quality can be affected anywhere in the product chain. Both the environment and the set of genes of the animals have an effect on the final output. A problem facing the beef industry today is the significant variations in meat quality between individual animals, which is reflected in the uneven quality of the meat that reaches the consumer. If the quality of meat in stores varies significantly over time, the consumers? trust may decrease.

This thesis has been carried out in cooperation with a company which develops mobile sensor platforms. The sensors measure different types of data such as temperature, pressure etc.. They will communicate through the internet with a server that stores data in a database. This system will be controlled and monitored through a web page. The project's aim has been to develop this system and to implement a server, a database, a website and a client application that simulates sensor signals.

Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.

This has led to ademand for structure changes and reorganizing through the company.

This master?s thesis aims to study the practice of separating popular genres of fiction from the rest of the fiction stock, often seen at public libraries. The method being used is critical discourse analysis according to Norman Fairclough?s three-dimensional conception of discourse. The textual dimension of this analysis is the book shelf itself and the sociocultural practice is the everyday practice at a public library of supplying and mediating books to the visitors.

The food industry is one of the fastest growing industries in Swedish e-commerce today. However, e-commerce still represents a very small part of the total food sales in Sweden. Experts have noted that, in order for e-commerce to expand in this field, Internet food sales must increase.The aim of this study is to form an understanding of why Swedes do not purchase more food products online. The theoretical framework consists of various marketing theories concerning consumer behavior and the acceptance of new innovations. The methodology used for the purpose of this study has a qualitative approach and in order to answer the questions at hand two focus groups were assembled.

The purpose of this study is using McDonald?s in China and Sweden as a case to find out how fast food restaurant retailers combine adaptation and standardization with symbolic attributes of store atmospherics under different cultural background, and find out possible reasons. The study used McDonald?s in a case format to study in-store atmospheres. Further, the research has an investigating and explanatory qualitative approach, collecting the empirical data through observation with photos.

A purchase decision can be seen as a multifaceted context that raises many unanswered questions. Understanding the consumer's evaluation of alternatives is complex and should be studied at a deeper rather than wider scale. There is a problem for retailers to understand how the consumer manages a purchase decision in a retail setting with durables goods that generates a higher effort. The aim is to describe the decision rules used by the consumer and how they are expressed in this context. A better understanding of which ones they use and how they are conveyed will help retailers to create effective marketing solutions that generate positive outcomes as increased profitability and customer satisfaction.

This Master of Science thesis project handles issues around managing data from the digital tachographsystem. European legislation states that companies must download the data of the digital tachograph systemand store it for at least one year for control purposes. The system stores data on the vehicle unit located inthe driving compartment and on smart cards personal for each driver.Acquiring data from the previous analogue tachograph was done instantaneously since the data wasphysically printed to a circular paper chart when driving. To acquire data from the digital system one mustperform a download from the vehicle unit and later transfer it to some form of backup solution for longterm storage. Data must also be downloaded from the driver smart cards.Download of data from the vehicle unit is the most time consuming task and may take up to 30minutes pervehicle.
