To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..

The aim of this paper is to examine the youth library PUNKTmedis' work methods to adapt itself to the youth. Improved communication with this user group is the starting point for the new work methods. We have chosen to view the increased cooperation between the library and the youth as an adjustment to market demands. We have noticed the possible existence of an antagonism between on the one hand the traditional role of the public library of adult education and on the other hand an adjustment to the market demands. Adult education and the adjustment to market demands is seen as contributing to the image of PUNKTmedis.

The white-backed woodpecker is a forest bird being critically endangered in Sweden. The species is dependent on older forests rich in deciduous trees and dead wood. The main problem for the survival of this species is present shortage of habitat. Conservation work on this umbrella species is at present focused on finding remaining or emerging habitat networks. Large areas are scrutinized in search for suitable habitats to be protected or managed for the species sake.

AbstractThis study deals with motivation as an overall concept, from a student perspective. It encompasses factors that could directly affect students and their positive or negative motivation, concepts such as relationships, communication, expectations and interactions and their importance to my informants.The study also discusses certain theories to show the different ways of defining motivation, specifically in relation to my informants and their and my conclusions. My ambition is to establish the importance of the concepts mentioned above, as well as perspective changes to the enhancement of the performance standards of a good teacher.The purpose of this work is to describe, understand and clarify the external and internal factors that affect motivation. In order to achieve this purpose, I chose to use a method of qualitative interviews with three students, with different backgrounds, schools and conditions but with a lack of motivation as a unifying characteristic. The research questions were as follows:What factors influence students' motivation?   What impact do achievement targets have in relation to the pupils? own motivation to learn?How important are teachers' expectations for the individual student's motivation?Within this study sub-concepts such as importance of expectations, relationships, and significant others are, according to my analysis, of great importance.

In today?s competitive market, design is an important element for the companies. They must succeed with delivering an increased value and an experience for the consumer to be able to survive. The Swedish company?s have become better in the design area, the higher standards the consumer?s demands forces the company to invest more in design.

Requirements management is an important part of the software development process. The success of a project may depend on how this is handled. Even though several research studies indicates that more attention should be paid on non-functional requirements, the primary focus in practical projects still regards identifying functional requirements. Especially the prioritization of the non-functional requirements has been proven to be of great importance for the success of a project.This report investigates basics in agile requirements management involving opinions from experts from a software development company. This is done with help of existing literature and interviews with key actors involved in prioritization at the company.

This Masters thesis concerns how library and preschool can cooperate in supporting childrens language development and especially that of bilingual children. We have investigated how librarians and preschool teachers different competences can complement each other to gain the best result in work with childrens language development. This study is based on qualitative interviews with four librarians and three preschool teachers. The answers from them have been analysed according to different categories. Our results show that both librarians and preschool teachers think that bilingual children need extra support and that it takes longer to learn two languages.

This research is about six pedagogue´s and their reflections about the size of the children´s group in the preschools. Then I will discuss the pedagogue?s recommendation on the significance of the size of a children´s group learning and development and it´s practical significance for the preschool function. The pedagogue?s statements will be discussed in relation to The Swedish National Agency for Education (TSNAE) guidelines on group size.The theoretical framework of this essay will take an overview of the social cultural perspective, the group size and its significance for both the children´s learning and development, for interaction and communication and TSNAE advice and guidelines.

The aim of this essay is to give the reader an idea of how the European agricultural policies have developed, in regard of sustainable development, since Sweden became a member in the union 1995. The main aspect that?s been investigated is the issues regarding sustainable development and how the issues regarding the ecological farming methods have been dealt with. My research questions are:- How has the European environment- and agricultural politics changed since Swedenjoined the union in 1995?- What consequences have the changes had for ecological farming?The answers to the stated questions are that there have been several treaties in the field of environmental development of the agricultural policy, starting with the Maastricht treaty and ends up with the European Action Plan for Organic Food and Farming.

Numerical simulations play a vital role in both static and dynamic stability assessment of electric power systems and the foreseeing of voltage collapse. Simulations performed by Svenska Kraftnät(SvK) are mainly done in the specialized voltage collapse predicting software tool, SPICA and the more all?purpose software tool, ARISTO.The grid operators at SvK use SPICA to predict the maximum transfer limit at specified sections (in this report the section in concerns is the southern part of Sweden i.e. interface1 4). SPICA is mainly used as an online application by using actual states from the grid, these states update every quarter of an hour.This thesis is a continuation of the master thesis SPICA ? ARISTO JÄMFÖRELSE by Jakob Katzman and Johan Fält.

A relatively new sector in the world is the one concerning social enterprises and their development. Social enterprises are enterprises that are working with social objectives, their goal is not to make as much money as possible. This essay is looking at the development in social enterprises in two countries; Great Britain and Sweden and how the employee numbers in the enterprises have changed over time. The result shows a large increase in the number of employees in the enterprises in Sweden, however the enterprises in Great Britain does show a declining number of employees. This essay also tries to examine whether a couple of external factors, taken from a series of already existing theories, are affecting the possibility of development in these enterprises.

The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground.A comparison of theoretical data of different WES-based terrain interaction models and a comparison test data from a full scale field test is presented.

The aim of this paper is to examine how The Swedish Library Classification System, also known as the ?SAB-system?, has classified popular music. The investigation is limited to the classification category of ?Yx Jazz, Rock and Popular Music? within the SAB-system. The development of this category is studied.

The aim of this study is to investigate methods of collection development, the users? influence on selection and quality aspects, focusing on non-fiction literature in Swedish public libraries. To find out opinions of collection development, I use the method comparative literature study. Antonio Gramsci?s concept hegemony forms the theoretical background, and hegemony as concept is related to a library context by using Maj Klasson?s text on the librarians? different positions of authorities.
