The amount of cargo has since the 1970s increased in Sweden and the road traffic accounts for a large part of the transported volume. In Stockholm County the amount of cargo is calculated to be doubled in size from year 2001 to 2020 which means a greater need for transport is required. Much of these transports are being carried out by haulage companies of varying sizes which acts externally as carriers for their customers. All of this despite a greater awareness, laws and demands regarding environmental performance.The trend shows that the haulage industry in Sweden are moving towards fewer but larger haulage companies, which means that the competition is getting tougher for the smaller haulage companies. Smaller haulage companies and research about their competitive strategies is a neglected part of this industry.

This examination work aims to describe how a supply chain around the biggest pellets factory in Sweden will be configured in a logistic perspective. The plant and associated infrastructure are in the building phase and will have production start on the 2 November 2009. The key question that is set in this examination work is to recognize the logistic processes which are essential for an effective flow of materials and information that link the source of supply with the ultimate customer. In order to get the answer, a flowcharting of these supply chain processes is required for understanding the pipeline activities such as input and storage of raw material, the production system and the output of pellets to the customers. The basis for this supply chain map is a model-based representation of these logistic processes and activities that are involved around the pellets factory.

The purpose with this thesis is to investigate how to design a urban space so that it is experienced safe and how to implement this at an actual site. Knowledge on the subject has been gathered through litterature studies and interviews with experts. Through an analysis of the site with surroundings and studies of projects with similar problems, practical actions have been observed. Part taking in the municipalities planning process has given insight in the projekt as an whole and the interests of different parties. There are many different opinions about what the word safety means. It is a feeling depending on situation, that is affecting our daily behaviour.

 The purpose of this thesis is to study the education of newly arrived 16-20 year old immigrants and how their education in the towns of Södertälje and Malmö matches up with national inquiry into the subject.The research questions in this thesis are as follow: What type of documents shape the work with newly arrived students? What's the preferred development surrounding the education of the newly arrived students nationally? What does the latest study, which is a proposed reform of the Gymnasium system, say about the education of newly arrived students?How does the local work connect with proposals of national investigations? Do the cities take responsibility for evaluating the education of newly arrived students? From arriving to graduating, what does the road to graduation look like for a newly arrived student? What is the curriculum of a newly arrived student?The methods used here are studies of investigations made primarily by Skolverket (The National Agency for Education) and Myndigheten för skolutveckling (The Agency for Development of Education), studies of local documents such as annual reports of quality and promotional material for programs at local Gymnasiums (High Schools), and interviews with local persons in charge of shaping the work with newly arrived immigrants.This thesis has not used theory as a foundation for structuring the analysis, but postmodern theory and the use of three dimensional power inspired the thesis.The conclusions made focuses on the future of the education for these teenagers at large and makes connections between the national investigations and the local work with immigration education.In order for these teenagers to be allowed to join the Swedish national Gymnasium, they need to learn Swedish, and integration seems to be an important part of learning Swedish quickly. .

The business potential of software defined radio (SDR) technology is studied by evaluating whether or not its characteristics correspond to those particular to a disruptive technology. The maturity of the SDR technology concept is illuminated by analyzing the opinions and perspectives of a selection of representatives for different stakeholders in the wireless communications market. Characteristics as, for example, the degree of consensus about the utility of SDR technology and the awareness of features and limitations are studied by application of the theory of technological frames. This theory helps us understand how and when technology evolution takes place. Finally we describe the value network structures of some potentially viable application areas for SDR and suggest some possible business opportunities based on SDR technology.This thesis is carried out as a case study and the research data is obtained from secondary sources, such as literature and Internet publications as well as interviews with people well experienced in the field of wireless communications.

The objective of this diploma work is to investigate a set of Multiple Input Multiple Output (MIMO) channel models compatible with the emerging IEEE 802.11n standard. This diploma work validates also advanced, innovative tools and wireless technologies that are necessary to facilitate wireless applications while maximizing spectral efficiency and throughput. MIMO channel models can be used to evaluate new Wireless Local Area Network (WLAN) proposals based on multiple antenna technologies. The purpose of this thesis is to investigate means of channel models and their implementation in different environments such as: Matlab, C++ and Advanced Design Systems (ADS). The investigation considers also a comparison between the channel models based on theoretical data and parameter setup to the channel models based on statistical characteristics obtained from measured data.

Previous studies of central tire inflation (CTI) in truck transport of roundwood have shown potential benefits to include more even wood flow and reduced road damage. The greatest benefits are found to be during periods of low bearing capacity such as spring thaw. No previous studies have examined geographical variations in the potential benefit of CTI-equipped trucks. The aim of the study was to develop and use a simple method for geographically prioritizing the use of CTI-equipped trucks within a forest company´s sector of activity.The host company for the study was Holmen Skog. The area studied consisted of Holmen Skog?s entire sector of activity extending from the province of Västerbotten to the province of Småland.

The purpose of this thesis is to analyze and propose improvements to the current procedure for cost estimations of purchased maintenance work at Banverket, the Swedish rail administration. This governmental institution is responsible for the procurement of maintenance services for the country?s railRoad network through open tenders. Due to the generally low number of contractors, it is particularly necessary to establish accurate cost estimates in order to assess the offers and ensure that a fair price is being paid to the suppliers. Several flaws associated with the current practice are identified and analyzed according to cost accounting theories.

The purpose with our essay was to examine what favourable factors there are for women to get out of drug abuse and from a gender aspect interpret how these factors are used in the treatment of female drug-addicts, regarded from the treatment personnel view. The questions we have focused on are: What are the favourable factors for women in the way out of the addiction. How can the use of favourable factors be interpreted from a gender aspect. In what way is the knowledge about these favourable factors used in the drug abuse treatment.To fulfil the purpose whit our examination and to get answers to our questions we performed an explorative examination and applied a qualitative method in the form of a half structured interview with five persons.The main features of the results in our examination were that unisexual treatment, the group and the friendship between women, children and pregnancy and professional and private social network were considered as the favourable factors for the women out of their addiction. Certain factors were used in the treatment as a way to socialize or resocialize the female drug-addicts to predominant social models of how a woman should be like..

Unmanned aerial vehicles (UAV?s) are nowadays greatly appreciated. The advantage over manned airplanes are great since UAV?s can be much smaller and therefore lighter. The goal of this project is to evaluate the performance of an environmentally friendly UAV using only lithium-ion batteries.

The aim of this essay is to investigate the implementation of The Social Orientation inSweden. The Social Orientation is a part of the new, one year old, establishment law and isaimed at all newly arrived refugees and immigrants. The aim of the law is to help establish allnew arrivals into the Swedish society by providing knowledge about life in Sweden. Theeducational program is at least sixty hours long and covers: the public authorities in Sweden,laws and regulations, work and education, healthcare, children and family issues in a person?smother tongue.In order to achieve my aim I have chosen two questions: How has the law been implementedin Swedens three counties: Stockholm, Sörmland and Uppsala? What conditions are there fora successful implementation?In order to answer these questions I have used the traditional, ?street-level bureaucrats? andnetwork perspectives and issues for my study of implementation.
