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.

Surveys show that consumers tend to avoid traditional marketing channels, leading the practitioners to use earned media channels through public relations (PR). This has also led to the use of covert PR. To understand the use of this communications method, the purpose of this thesis is to study campaigns, which have gained transmission in social media, by investigating how practitioners of three different campaigns motivate the choice to use covert PR.The study is based on a hermeneutic methodology and has an abductive approach. It is carried out by semi-structured elite interviews with six contributors of three different campaigns, using covert PR. The primary data consists of the empery of the interviews, while the secondary data consists of a theoretical framework of excellence in public relations, the PR practice and viral messages.The result of the study indicates the point of view that covert PR has given the campaigns a wider reach.

The purpose of this thesis is to evaluate three search engines with regard to retrieval effectiveness of information specific to Swedish users. Coverage and the precision in result descriptions are also examined. The three selected search engines are Google, MSN Search and Svesök. 30 queries were tested against the search engines and the first 20 result descriptions and results were judged for relevancy. Relevancy was judged by a binary scale.

The main purpose of this essay is to study the Swedish labor law concerning employees who are, aspire to be, or are expected to become parents, both men and women. Thereby accomplishing a gender perspective on the issue at hand. The study also take in to account the laws issued by the European Union, and their impact on the Swedish law system, so as to gain an international perspective. The laws regarding parental leave, both Swedish and European, involve protection for workers from being treated in a less favorable way than someone in a comparable situation, as employers are forbidden to disfavor any employee or job-seeker in basically all situations in the work place or in a recruiting context, if the disfavor is in any way related to the parental leave. The only situation where an employer is allowed to disfavor an employee regarding his or her parental leave, is if the disfavoring is a necessary consequent of the employee?s absence.

Today, some kind of laboratory results is required for around 70% of the diagnostics and follow-ups for diseases. In many of the cases the time from sampling to a result is very critical. Therefore the discussion of how to improve this situation has begun. For many analyses serum has been the routine choice for a long time but now it is disputed. After blood collection in a serum tube it is essential to wait 30-60 minutes before centrifugation and analysis of the sample, a long time for someone in an acute state.

Students today, in the banking system, are the least loyal group. Students are also the most costly group due to the large investments, made by the banks, for them. Banks have generalized all students in one category and have adapted their offering regardless of students? social statues. As the students banking needs are dependent on their position in their lifecycle, generalizing them in one group is not optimal.The aim of this thesis is to investigate those factors which influence students? choice of bank.

The purpose of this master thesis was to study the water system for mechanically cleaned water at Skärblacka mill, in order to find and evaluate possibilities of using energy more efficiently. The thesis also includes an evaluation of the software tool ?Pumpanalys?Skärblacka mill produces pulp and paper. The large amount of water required is cleaned mechanically through filters and called mechanically cleaned water (MR0). The MR0 water is pumped out to the factory by four crude water pumps.

This thesis compares four relevance feedback methods. The Rocchio and Ide dec-hi algorithms for the vector space model and the binary independence model and Okapi BM25 within the probabilistic framework. This is done in a custom-made Information Retrieval system utilizing a collection containing 131 896 LA-Times articles which is part of the TREC ad-hoc collection. The methods are compared on two grounds, using only the relevance information from the 20 highest ranked documents from an initial search and also by using all available relevance information. Although a significant effect of choice of method could be found on the first ground, post-hoc analysis could not determine any statistically significant differences between the methods where Rocchio, Ide dec-hi and Okapi BM25 performed equivalent.

Women and men's equal, or unequal treatment has long been a topic of conversation and the workplace is a place where the topic has been and continues to be in question. This study examines the jargon and culture within student-run companies in Gothenburg from a gender equality perspective, focusing on female and male perceptions. The study poses the research question: What does the culture and jargon look like in student-run companies in Gothenburg from a gender equality perspective? The choice of method for the study has been qualitative semi-structured interviews, which has been performed on current and former employees from several student-run companies in Gothenburg. The results show, on average, that the jargon and culture are perceived as relatively equal, but that there can be considerable variation across different areas.

The reason why this study has been made is the fact that a substantial part of students in the upper secondary school changes their field of study, during or after their first year. The aim of this study is to find out the reasons behind such changes as well as finding out the affecting factors. The study has been made in two steps, first quantitatively by a poll study and the second step is qualitative by interviews. This research has been made in both private schools and municipal schools, with the ambition to search for differences between these two separate school forms. The study shows that no general differences can be found in a comparison between them.

A common assumption in marketing is the wider variety of product a corporation has, the better for the consumer: more product - more choices. Companies often develop a line extension to broaden consumer range through product attributes including quality, function and design. These developed attributes within the product are not always optimal for the consumer. As a result, companies often become entangled in having a price higher than the cost and benefit of the products. This essay aims to analyze the consumer value of line extension products and how these evaluations relate to extended line product pricing.
