This bachelor thesis investigates the discourses on violence among pupils in a school environment. The overall aim is to gain knowledge on how it is researched, interpreted and understood. The methods employed are genealogical analysis, discourse analysis and intersectional analysis. The analyzed texts consist of research reports, articles, dissertations and government authority guidelines. The theoretical framework drawn upon is post modernistic theory, social constructivism and intersectional theory.

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.

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.

There is considerable variation between stallions in semen quality and fertility due to the fact that selection of stallions for breeding is not based on fertility or semen quality but on performance. The increasing use of cooled semen for artificial insemination has resulted in decreasing pregnancy rates. Therefore the equine breeding industry needs new methods for evaluation and development of sperm quality and fertility. This study is a part of such a project and is performed by SLU in cooperation with Flyinge AB. Ten stallions at the Flyinge National Stud were used in the study and three ejaculates were collected from each stallion.

Denna rapport behandlar ett examensarbete med målet att hitta en paketering för resursövervakning i nätverk (NPMD - Network Performance Monitoring & Diagnostics) samt centraliserad logghantering (SIEM - Security Information & Event Management).Arbetet har utförts över fem veckor och bestod av att undersöka vilka produkter som kan vara möjliga att leverera till Ateas kunder genom att ta fram förslag på produkter och sedan utvärdera dessa i en virtuell testmiljö.Efter att två veckor av arbetet passerat beslutades att enbart SIEM-produkter skall utvärderas då vi annars inte kunnat hålla tidsramen på fem veckor. De första två veckorna bestod mestadels av efterforskning av olika produkter baserat på ett antal kriterier.Applikationen ska:? Stödja mallar och regler för Payment Card Industry Data Security Standard (PCI-DSS)? Stödja korrelering av händelser? Ej vara open source eller en hårdvarulösningUnder resterande tre veckor installerades, konfigurerades och utvärderades de produkter som var intressanta för ändamålet. Utvärderingen av produkternas funktioner och egenskaper utfördes i en virtuella miljö. Resultatet av testerna är ett dokument som innehåller information om varje produkts förmågor samt betyg på varje produkt.

Previous research has established coaches' important role in developing elite athletes (Durand, Bush, Thomson & Salmela 1996). Athlete enhancement and assisting athletes achieve ?peak performance? has been a major objective for elite coaches as well as sports scientists (Williams & Kendall, 2007) Despite this common goal, research also question whether sports scientists and the research they pursue really effects coaches knowledge and constitute a foundation for today and tomorrows athletic performances (Bishop 2008).  This study examined elite coaches? needs and use of sport science research as well as the interaction between elite coaches and sport scientists. Following interviews of ten elite coaches, content analysis revealed that sport science is both a formal and informal resource of knowledge for coaches. Development of athletes is seen as the main objective of research retrieval and personal and/or direct contact with the sport scientist is considered to be the best way to assemble.

In query expansion (QE) terms are added to an initial query in order to improve retrieval effectiveness. In this thesis we use QE in the sense that a reformulation of the query is done by deleting the terms in the initial query and instead replacing them with terms from the documents retrieved in the initial run. The aim of this thesis is to, in a experimental full text invironment, study and compare the retrieval result of two different query expansion strategies in relation to each other. The following questions are addressed by the study: How do the two strategies perform in relation to each other regarding recall? What may be causing the result? Are the two strategies retrieving the same relevant documents? Two strategies are designed to simulate a searcher using automatic query expansion (AQE) either with or without relevance feedback.

This thesis is a product development project that was performed at Alfa Laval Tumba AB. In the past Alfa Laval have manufactured gas separators for engines where gas flows were cleaned from oil. A new business area for this kind of technology has shown to be the manufacturing industry where oil mist has to be separated from the vented air. Therefore a new and bigger design is needed to be able to handle the greater gas flows. A product like that would be a strong competitor on the market when the maintenance would be low in comparison to today?s equipment.During the project several concept suggestions were developed using customer interviews and research as input.

International expansion has long been associated with a positive trend that many companies, regardless of industry, choosing to realize mainly to expand its market share and hence its profitability. Various theories describe differentiated strategies to promote corporate expansion. Either they shall be financed by internal funds, or balancing equity with debt, or only increase leverage in order to achieve the desired results. This study focuses on the Swedish fashion market and its degree of internationalization. The purpose is to attempt to discern whether there exists a correlation between the degree of internationalization and its financial performance.The study was based on a quantitative approach where secondary data was collected so that we then would be able to perform regression calculations.

The latest thing in the area of environmental building today is energy-plus-house. The idea behind the energy-plus-house is to create a house that produces more energy than it consumes. To accomplish this, the house uses renewable energy, in this particular case solar energy. With the help from a proper construction and thoughtfully projected installations you can achieve a surplus of energy. The surplus energy can then be sold to the surrounding buildings and thereby conduce to a financial profit for the household.

The purpose of this thesis is to describe and analyze how the mining equipment producers on a global market manage to handle the changing conditions concerning customer value. Our approach has been a comparative analysis between two different sites in order to answer the purpose. The case studies at Metso Mining have been made through interviews and visits at two geographical markets, South America and Scandinavia. The theoretical framework applied on our empirical findings is based on Blue Ocean Strategy, Customer Value and Resourced Based View. The empirical foundation is based on interviews with Metso Mining employees at Sorocaba in Brazil and Kiruna/Gällivare, Trelleborg and Staffanstorp in Sweden.

Heavy duty vehicles often have problems with traction during the winter periods. For vehicles that can lift tag axles it is possible to increase the normal force on the driven axle by lifting one or more tag axles, this will then increase the propulsive force of friction. This however increases wear on both road and vehicle. A possibility to reduce the wear while achieving nearly equivalent traction compared to lifted tag axles is to allow the vehicle to regulate the normal force by lowering the pressure in the air suspension associated with the tag axles or by the lifting of these axles. The vehicle would then by itself be able to set just the right amount of normal force on the drive wheels to avoid unnecessarily high normal forces while maintaining sufficient traction.The purpose of the report is to find out which parameters affect heavy duty vehicles when driving on slippery slopes and how traction can be improved.

This study is focusing on students at compulsory level and their performance in national exam tests when the students first language is taken into account. Students in Swedish schools with non-Swedish speaking parents commonly follow language classes for limited Swedish proficient students. How does this affect their results when tested in other subjects as physics,biology and chemistry? A general claim is that national tests can provide data for balancedand fair grades. This view is challenged in this paper, through Principal Component Analysisof test results that shows a difference between schools when the schools social position and share of limited Swedish proficient students are measured.
