This thesis deals with the development of a specification regarding a push-button, which will be used to control the gear-shifting function in an automobile. In addition to this the author will describe different techniques and theories that have been helpful in achieving data and results for the specification.Kongsberg Automotive AB, is located in Mullsjö, Sweden, the company supplies parts to the automotive industry. In the research and development department, R&D, there is a group that works with development of Shift-By-Wire systems. In an automobile with a Shift-By-Wire system the communication between the gear-shifter and the gear-box occurs electronically. The mechanical link is, in most cases, taken away and replaced by the digital system.

This report describes my degree project. For my degree project I made a demo for a game idea that I've developed, and implemented for use with Xbox 360. The idea was about converting the feeling and gameplay of old 2D side-scrolling platform games into 3D, viewed from a first-person perspective. The Xbox 360 version of the demo was also submitted for the game competition Swedish Game Awards. In the report, I explain this idea more extensive, what software I used to implement it, and how I implemented it. Finally, at the end I clarify the results and discuss fulfilled tasks and future improvements.

This report deals with RFID systems and how to detect nearby tags with the Mifare standard using only a microcontroller and an antenna circuit.The aim was to investigate whether there was any possibility to continuously search for a nearby tag for a system operated with batteries without compromising   the lifespan of the battery. At this time the system would take too long time to wake up and look for a tag to give a satisfactory battery lifespan, which should be done a couple of times every second.The report has two issues, namely:Is it possible to direct the microprocessor to detect and identify a nearby tag after the Mifare standard?What hardware is required for this to be possible?As the research method to provide answers to the above questions an action research was used. This approach has meant that the group worked on information retrieval, examined existing solutions, tested their own solutions and documented the results.The group examined an existing solution that can search for nearby tags with minimal energy consumption. An antenna circuit was built that was connected to the processor.

Today?s Sweden becomes more and more multicultural, with a mixture of many different languages. Many children are raised to learn two or more parent languages. If you work as an educationalist in preschool you will probably come in contact with these children. The question is how you should treat them and ease their development of languages.The purpose with this work is to find answers to the question if bilingual children develop their languages by the same method as monolingual and how one as an educationalist can make these children?s development of language easier.The papers preface is a part of literature that describes different researchers view on the bilingual children?s development of language and how one, as an educationalist, can ease it.To my study I have chosen to interview three educationalists in preschool who all work with bilingual children.

The concept of leadership development plays an important role within the modern organization. As a result of the increasing interest in developing leadership competencies, investments in leadership development programs are becoming a common part of business strategies. However, the return on those investments is seldom evaluated. The reason for this is considered to be the complexity created by the many factors that influence leadership but have no relation to the program. This is a case study based on interviews with participants from a one-year leadership development program that was carried out at AB Previa.

The aim of this study was to gain insight into how two enterprises work with competence development and thereby study how the relationship between competence development and workers, employees, look like. The focus was on the workers motives and motivation towards a participation in a competence development course, their attitude to education, and how the transfer of skills gained from the course, into the workplace looks like. Further on, the work situations influence on the workers competence development has been taken into account.In the study, six people were interviewed in the role of either manager, coach or course participant who are employed in two different enterprises in the south of Sweden.The results showed that the participants were motivated by a strive for personal development or that the participants viewed education implementation as a part of the professionalcareer, which has resulted in a positive attitude towards the competence development course. The managers? motive for decisions about education was to change the prevailing attitude among the staff for the better and thereby strengthen the company?s brand. The work situation has encouraged the desire to participate in developmental education as the feeling of control has encouraged the workers to further development.

If one looks at physical planning in Sweden today one can see that while talking about densification of existing development, reduced emissions and careful use of important land, urban sprawl is a fact with development of sheer residential districts in the urban edges and shopping malls in each and every municipality. As sustainable development is an essential goal for physical planning to strive towards, it is worth questioning if the direction of today?s planning will lead to the goal. A sustainable development can be seen as an obvious to goal aim at. In reality the aim means a hard and complex work.

I have taught pupils in several schools in eighth and ninth grade in ?weak? groups in mathematics. Most of them seemed to possess potential, but lacked motivation. Even though I tried several pedagogical methods, these approaches failed to engage the students. This prompted thoughts that this may reflect a broader structural problem about the organisation of education in Sweden.

Franchise theorists have to a large extent failed to keep up with the actual development in global franchise chains. The recent emergence of fast growing multi-unit-franchisees has fundamentally been ignored, and it has been claimed that the new phenomenon can be regarded as a mere replication of the franchisors? structure and control system into sub hierarchies. This study however, suggests that the reality is more complex. Through conducting case studies of two Nordic multi-unit-franchisees, new theories are built explaining how and why control systems are designed the way they are.

ABSTRACT:The aim of this essay is to analyze whether the development of the Principles of War in small states´ doctrine has been influenced by the doctrinal development of alliances after the start of an international cooperation.The author suggests that the development of the Principles of War can be understood through theories of doctrinal development. The theory used for this analysis states that small states depend on alliances, such as NATO, and therefore adapt their doctrine to better match the doctrine of the alliance. Since the Principles of War are the foundation of doctrine, such an adaption should lead to an adaption of the Principles of War as well.The analysis will be made using Swedish Army field manuals as a basis. These will be compared to NATO´s, in order to see whether or not Sweden has adapted its Principles of War following its membership of the Partnership for Peace.The results show that today the Swedish Principles of War are more similar to NATO´s than they were in 1982, which suggests that they have been adapted to better match those used by NATO. Although this essay does not analyze the reasons why, the results imply that theories of doctrinal development also include the development of principles of war.

The purpose of this essay is to do an ecocritical reading of Vilhelm Moberg?s The Emi-grants from 1949. By asking and answering the three following questions; How does a system present itself, What are the different reasons for emigration; Why does differentsystem fit some well and some not.By using two articles from Green Planets - Ecology and Science Fiction to illus-trate two different views; Different parts value in an ekosystem and The Ship as an ecosystem. I have also created, based on the literary text four different terms concern-ing the dynamic system; Stable, Static, Unstable and Collapsing systems. I have found that all system goes through changes, some drastic, that changes the way the parts of the systems fit with in it.

Every year, thousands tons of edible food are discarded by the grocery stores. This is food that could have gone to people that?s in need of it. In many countries, so called food banks are established in order to supply welfare organizations with this kind of food. Today there is no equivalent system existing in Sweden.

This Thesis aims to explore how to integrate an IT-system for facilitating anorganizations work with Continous Impprovements.This is done here by examining and analyzing the process within a handful ofcompanies who seem to have been successful with their own implementations. Thestudy is focused on the implementation of one particular system, "System C2".Simliarities and differences between the companies, and the established rule of thumbfor these kind of activities are focused upon. This to emphasis how another actormight emulate some of the apparent success.Part of the core question is found in the title, since Continous Improvement is oftenseen as a relativly low-risk activity, is it then also possible to take a low-risk slow pathto the implementation of such a system in the entire organization?.

Mobile application demands a lot of attending to the program code. There are lots of different development platforms that can be used for development. Not only for the specific operating system there are also lots of different cross-platforms that should minimize the amount of program code. This report is comparing the way of creating an android application in the cross platform Xamarin versus in the platform Eclipse using the Android plugin. It contains a part about the architecture of Android and its functions.
