A cars powertrain consists of everything that is needed for its propulsion. The components in the driveline that transfer the power from the engine to the driven wheels are not absolutely stiff, hence they will wind up due to the torque and act as torsion springs. If you suddenly demand a bigger torque by stepping on the accelerator pedal, a so called tip in manoeuvre, and that torque is acquired from the engine as quickly as possible, the driveline will not be able to transfer that fast torque change due to its weakness and as a result it will start to oscillate. These oscillations will be transferred to the driven wheels and make the car to accelerate jerkily which will be experienced as uncomfortable by the passengers. Furthermore, there is a backlash in the driveline that will make the weakness in the driveline even more excited than it should have been if the backlash did not existed.To avoid too big problems with these oscillations there is a control system that controls the demanded torque.

When developing software that is meant to be distributed over several different computers and several different networks while still working together against a common goal there is a challenge in testing how updates within a single component will affect the system as a whole. Even if the performance of that specific component increases that is no guarantee for the increased performance of the entire system. Traditional methods of testing software becomes both hard and tedious when several different machines has to be involved for a single test and all of those machines has to be synchronized as well.This thesis has resulted in an exemplary application suite for testing distributed software. The thesis describes the method used for implementation as well as a description of the actual application suite that was developed. During the development several important factors and improvements for such a system was identified, which are described at the end of the thesis even though some of them never made it into the actual implementation.

This study aims to examine attitudes and conceptions of staff who work with mentally disabled persons, concerning normalization and gender. Six qualitative interviews with such professionals were performed and subsequently analyzed. Since the method of this study is qualitative, no claim of generalizability is made. The interview material has been categorized into themes by means of coding. The result of the study is presented according to those themes.

As companies grow, their need for computing power will increase, which traditionally resulted in companies having to invest in more IT resources. Now, with cloud computing, companies can easily hire computer power over the Internet, on-demand. Cloud computing offers a highly scalable environment where companies can store data and host their services. This paper employs a qualitative study with interviews and literature studies to explore opportunities and challenges associated with cloud computing from a system developer perspective. The aim of the paper is to find out how cloud computing changes the conditions for system development. The paper contributes with four different opportunities and challenges that the system developer must handle to succeed in the world of cloud computing.

How do men who define themselves as feminists create and maintain an identity as men? In this qualitative study four men involved in feminist organizations were interviewed about their views on women, men, sex and feminism. Theories of language, psychoanalysis and ethics were utilized to further our understanding of the material these men produce in their effort to define themselves. Our object of study is the text, which we believe holds the key to understanding how an individual shapes his world and himself. The result is our interpretation of the text and its underlying mechanics.

A large amount of our time is spent indoors in an artificial climate. To make the experience pleasant there are requirements on the ventilation and the heating system. At the present time the most common form of heating is a radiator system complemented with a ventilation system. A ceiling heating system with combined heating and ventilation can replace the two separated systems. The benefit with a ceiling heating solution is that it saves space since the radiator system is no longer needed.

This report studies how the divergence between men and women is manifested in the physical space and how the representation of room recreates this divergence. Spaces are coded and women have traditionally been associated with private space and men with public space, leading to that the home is encoded as female space and public squares as male space. Thereby women lack a natural place in public space. The National Board of Housing, Building and Planning (Boverket) wants to change this situation by enforcing safety-creating measures based on gender equality theories.I have studied what potential risks the project initiated by Boverket as well as discuss the potential problems with representation. Can representation be used without freezing the space? I also search for methods for working with a gender perspective without reproducing gender stereotypes and roles and avoiding encoding the private as female and public as male? Also I use a public seminar with urban planners, artists and architects to retrieve how we work with these issues today.I conclude that city planning needs to incorporate new strategies of thought that does not divide space, e.g.

The thesis describes a completely new biofuel system to generate particle-free heat from combustion of ash-containing biofuel particles at high temperatures.The suggested system gives opportunities to introduce biofuels in new areas.Main components in the suggested system is a heat radiating combustion chamber intended for pulverized wood, combined with regenerators to extract heat from flue gases and simultaneously preheating the combustion air.The thesis contains a description of the suggested system, theoretical considerations, calculations regarding the combustion, and includes results from tests performed.The results from calculations and tests performed concludes that the system is workable and possible to apply..

Syftet med undersökningen är att ta reda på om begreppet ?Tekniska system? tas upp i förskolan. Dessutom undersöks hur förskolorna arbetar med teknik enligt den reviderade läroplanen, Lpfö 98.Som metod användes enkäter där pedagoger satt i arbetslagsgrupper och besvarade frågor. Enkäten används för att få en bättre bild av hur ålder, kön, tidigare utbildningar och yrkeserfarenhet förhåller sig till kunskapen av teknikämnet.Undersökningen visar att alla förskolor använde sig av begreppet tekniska system på ett eller annat sätt i samtal med barnen, till exempel vid toalettbesök, samt frågor ?vart tar rören vägen vidare till reningsverket??Vidare framkommer det att fler fortbildningsdagar och studiebesök är önskvärt för att pedagogerna ska få en större vetskap om begreppet tekniska system.

The aim with this masters thesis is to investigate how gender is presented in Swedish picture books, in order to give librarians and other actors in the field knowledge about what kind of books they supply impressionable children with. I investigate if and how the changes concerning gender-equality in the Swedish society during the last 25 years are reflected in childrens literature, and compare how men and women are portrayed in four books from the early 1980s with four books from the 2000s. My study is delimited to three aspects of character formation, introduced by Maria Nikolajeva: description of psychology, actions and relations to other characters. It is carried through by consultation of Yvonne Hirdmans theory of how men and women are held apart and that the man in this relation constitutes the norm as well as Nikolajevas list of typical male and female characteristics. By reading and interpreting the chosen books, I analyse both text and pictures.

Young children get affected and influenced by people?s thoughts and preconceived ideas about the difference between boys and girls. How they should behave and how they are supposed to play and interact with different toys.In the goals for what the school and teachers will achieve it says in the curriculum for preschool that teachers are supposed to counteract the traditional gender roles.To get answers to the question at issue, I collected 48 individual plans of development and I have performed four observations. I put all facts together and compared the results.The main result in this study shows that the traditional gender roles are being reflected in the children?s plans of development.

The purpose of this study is to use a qualitative approach to get an understanding of what is expected of social workers targeted towards women managers in social services. Nine social workers were interviewed. The empirical data was then analyzed on the basis of gender theory. Respondents did not see their supervisor as a manager but more as a social worker with special tasks. Our empirical data indicates that there is a strong belief that men and women possess different properties.

The concept of democracy is of importance to the Swedish educational system. The best proof of that is the central position democracy has had in the education program we attended at the Örebro university. This study analyses the concept of democracy and its leading foundation, namely the so-called ?deliberative dialog?. The last is belived to be an ideal of democracy which schools in Sweden should follow.

The purpose of this Master thesis is to examine how college library managers perceive shelves of book reservation system in an integrity perspective. Privacy is an important part of everyday life in the society of today and according to some people, for example a former library lawyer in the Swedish Royal Library, these shelves conflicts with the Swedish law of Secrecy (Sekretesslagen 9 kap. 22 §). I am therefore interested in how they perceive this system: what weaknesses and strengths it has, why they implemented it, how they have interpreted this law. To answer this I have used a qualitative method called phenomenography and done interviews with five college library managers.
