This thesis deals with the numerical 3D simulation of a four stroke, spark-ignited, internalcombustion engine, which is mounted on a high performance motorcycle. The work, carried outin collaboration with Politecnico di Milano and MV Agusta, focuses on the simulation of theintake, compression and expansion stroke, including combustion simulation, using an opensource CFD code.Simulation of internal combustion engines offers a great challenge in the field of CFD research.Moving boundaries of the solution domain, caused by the motion of the piston and valves, leadsto deformation of the computational grid, with decreasing quality of the solution as result. Basedon this, a previously developed mesh motion strategy was employed where a number of meshesare used to cover the whole simulation cycle. Within each mesh interval the internal cell pointsof the mesh are moved to account for the boundary motion of the piston and valves. This strategywas previously applied to simplified geometries as well as real engine geometries.

Research within gender and leadership has often focused on leaders in male dominated work areas, but quite recently interest has arise for examine leadership in female dominated work areas. This thesis analyzes possible differences connected to theories about gender stereotypes that may exist among male and female leaders within a female dominated organization. Further, possible underlying reasons to why or why not differences between genders might be found are investigated. The research question is addressed through a single embedded case study design at the Swedish public organization Försäkringskassan. The primary focus is middle managers, and twenty qualitative interviews were conducted with leaders and co-workers at two local offices and at the organizations headquarter.

This report relate a concept study that consider a number of different proposals to improve the overcharging system in BAE Systems Ha?gglunds tracked vehicle series BvS10, to maintain sealevel power at extreme altitude.At high altitude the power losses beacuase of the air density that decreases, which results in less fuel can be burned. The decreasing of air density also gives rise to fatigue failure of the turbocharger unless power is reduced.The proposals shall be as required by BAE Systems Ha?gglunds economically sustainable and defensible from a packing perspective. That means the selected solution must have a reasonable price tag and at the same time a minimal impact on adjacent components.The basis for this thesis is based on benchmarking of both the auto industry as the flight industry, to find inspiration and tips for improvement.Some of the concepts have after gathering facts and calculations been excluded while other solutions has been considered as workable and thus interesting for BAE Systems Ha?gglunds.Initially the current turbochargingsystem was analyzed in order to determine the starting point and thus be able to fix the current problems surrounding high altitude driving.

The purpose of this study was to investigate the problems of building a new region in the Southeast part of Sweden. The idea of a big south Swedish region is brand new; no former studies in this area have been done before. The main analytical focus of this study is legitimacy, identity and democratic credentials. The study has been carried out by interviews with several leaders in organizations working with the collaborations of the smaller regions in to the big region. The method of this study has been a single-case study and dialogue interviews.

The study examines the massacre of the garrison of the castle of Kalmar in 1525 and its causes. The goal of the investigation has been on the one hand to elucidate the most probable sequence of events, and on the other to identify as many different plausible explanations to the massacre as possible. For this end, four contemporary sources have been examined and compared in their details. To enable a broad basis for interpretation, the author has consulted various works on the themes of warfare, soldiers and violence in the late middle ages and the sixteenth century. Apart from political aspects, the study highlights social and cultural conditions as important factors in explaining how the massacre could be carried out without provoking any single part of society.

Many researchers emphasize the increasing strategic importance of supply chain management, but there is still a lack of concrete guidance for managers faced with strategic decisions in supply chain. Within decision-making theories, the rational decision-making model is the most commonly used. This because of its suitable foundation, enabling a structure to the complex decision process. The rational decision-making model is today not developed to include the aspects of strategic decision-making made in supply chain. The purpose of this research is to adjust a structured rational decision-making model, making it applicable for strategic decision-making in supply chain.

The great economic impact of startups on society has made these types of companies an increasingly popular subject for research. Though no single definition of the word startup currently exists, one could define it as a temporary organization in search of a scalable, repeatable, and profitable business model. Seen from a historic perspective, tech-startups in particular should be considered a new phenomenon and the topic is still relatively unexplored. This study investigates the structure in tech-startups during their first months of existence and compares it to the structure that prevails when the companies have recruited at least five additional employees. In addition, the study explains why these changes occur.

Tången 2 is a building situated in Stockholm, Sweden. It´s built in the 1930s and contains both residences and businesses. The property owner, Diligentia AB, wants to lower the energy use in Tången 2. This report consists of an energy audit which clarifies the specific circumstances linked to Tången 2. Collected knowledge is then used, together with the results from the literature study, to decide energy measures to proceed with.

The purpose of this paper is to examine the role of logotypes within the visual identity and identify possible reasons that motivate companies to change their logo. This paper should also clarify how different parts of the visual identity affect each other and how they are interconnected. The thesis research question is formulated with the purpose in mind and has led to the following question: How can a logo change contribute to enhanced visual identity? Since we wanted to obtain a better understanding of the chosen research area with help of interviews have we chosen a qualitative method for this thesis. During the process we have let the empirical material control the chosen theories.

In our study we examined recurrent patterns and changes in the representation ofhomosexual persons in Swedish daily newspapers 1987, 1997 and 2007.We analysed articles about HIV-infected persons and articles with a view to portray thelife conditions of gay and lesbian persons from the three different years. We chose toonly analyze news articles that intend to represent real human beings, which mean thatwe did not analyze reports that only reproduce abstract knowledge from authorities.With analytical tools from semiotics and discourse analysis we identified some recurrentpatterns in the representation of homosexual people. We found that a recurrent pattern inthat when homosexual people are seen as groups, they are described as deviant,discriminated and some times as a threat. When portrayed as individuals the nonanonymouspersons appear in articles and pictures as normal, strong and healthy. Lesbianwomen are not represented in the articles from 1987, but in articles from 1997 and 2007they appear as unhappy when single and happy in a relationship.The results also showed some interesting differences in news representation ofhomosexual persons between the three investigated years.

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.

In 1996, the Swedish government deregulated the Swedish electricity market. As a consequence of the deregulation, Swedish customers could start to freely choose between different electricity companies. Different enterprises have tried various strategies in order to shape their image to attract new customers; often focusing on an image revolving around price and environmental friendliness.The purpose of this essay has been to analyze customers? relations to the electricity market. In order to analyze customers? relations a quantitative study has been conducted; focusing on customer satisfaction and customer commitment.

A change towards using more biofuels than fossil fuels is taking place in Sweden, and in many other parts of the world. This makes the use of fuel pellets increasingly popular, causing a greater demand for sawmill sawdust products. There is a trend towards the use of multiple types of shredders, instead of a single type in each sawmill. The purpose of the study was to characterize the different flows of saw particles that can be found at Sävar såg when cutting thick or thin wood with different cutting techniques. The saw particles size, shape, moisture content and heat value were analysed by the cutting stations: first cutting fast and slow, second cutting fast and slow, grading fast and slow and planning.

Intresset i denna studie låg i huruvida organisationsstruktur påverkar den interna kommunikationen. Studien utfördes i samarbete med Region Halland. Avgränsningen gjordes till HR-verksamheten centralt, personalchefer och förvaltningschefer, där syftet med undersökningen var att beskriva och analysera upplevelsen av kommunikationen däremellan. Alla organisationer behöver kommunikation för att existera, det är kommunikation som utgör grunden och framgången för en organisation (Falkheimer & Heide, 2007 15-33). Genom kvalitativa samtalsintervjuer och inläsning på teorier om kommunikation besvarades nedanstående frågeställningar: Hur sker kommunikationen mellan HR-verksamheten centralt, personalcheferna och förvaltningscheferna?Hur påverkar organisationsstrukturen kommunikationen och hur upplever medarbetarna att organisationsstrukturen påverkar kommunikationen?Går det att identifiera eventuella kommunikationsproblem och i så fall vilka?Vad upplevs som effektiv kommunikation och vad upplevs fungera bra idag?Vem upplevs ha ansvar för att information skall nå fram till den eller de som är tänkt? Resultatet visade bland annat en upplevd otydlighet gällande information, svårighet med samordning, problematik kring förvaltningarnas storlek samt resurser på varje enskild enhet och svårighet att se organisationen ur ett helhetsperspektiv..

Wireless communication is becoming more common, a relatively new technology within the area is Bluetooth Low Energy. It?s been developed to be energy efficient and in regard to compatibility. Alongside the growth of wireless technology, scientists and companies are looking for new areas of use. One of these is localization, which means to determine the position of a moving device with the use of stationary devices, an example of this would be GPS.This report means to evaluate indoor localization using Bluetooth Low Energy and was made for Combitech AB in Jönköping.
