In this Master thesis, microwave connections between circuit boards are constructed. The primary frequency band is the X-band (8-12 GHz). The purpose of the connections is to enable a more simple and cheaper way of mounting the circuit boards inside a container. The connections have been designed and evaluated, using different computer programs. A few prototypes have been built and measured.

This paper aims to explore the phenomenon urban wind energy, its visual effect on built environment and the factors that affect the opinion towards new elements in the city. A place study of the city Gävle serves as a complement to the theoretical part of the paper. The theoretical discussion opens with an account for the technical and economical conditions of urban wind energy. It presents the technical basics, different types of turbines and a discussion occurring wind related techniques in built environment. Today, the knowledge of how the wind moves and acts in the rural landscape is quite good.

A large number of system development projects are allowed to proceed for too long, and leads to undesirable project outcomes. Research shows that more than half of the authorities involved reported that at least one of their projects have exceeded their budget, and that a third of all the projects had exceeded the budget. This problem led to the following research question: ?Which factors can explain projects continued escalation within public authorities?? To answer the question, a qualitative case study of the Swedish police?s implementation of PUST, a sort of case management system was conducted. The project received considerable media attention and a large amount of criticism was directed towards the project, partly because the project exceeded the timeframe and budget set at the start.

This is a study on how a group of ten pupils choose their upper secondary schools (gymnasium). All pupils are ninth graders in a middle school in Husby which is a suburb of Stockholm. Like the big majority of Husby citizens, they all have immigrant backgrounds and their time in Sweden varies; some are born here while others are born abroad and migrated later with their parents. My aim was to understand their upper secondary school choices through own and their parents? "cultural capital".

Since the Human Immunodeficiency Virus (HIV) that causes Acquired Immune Deficiency Syndrome (AIDS) was discovered in the 1980s, the condom has scientifically proven to be the only technological device that can prevent transmission of the virus during sexual intercourse. This technical approach to the HIV has strongly emphasized that prevention is only possible if the condom is properly used. However, as a technological artifact the condom has shown that its use is laden with values. The question of values on condoms has brought in a heated debate on the moral justifications of its use. In Malawi, just as in other African countries, the Faith Community has rejected the Governmentsplea to promote condoms as the preventive measure against the virus.The Faith Community has emphasized on abstinence and mutual faithfulness as the only reliable means to the prevention of HIV/AIDS.

Single vehicle accidents are one of the most common types of accidents that occur on the Swedish road network. Depending on the design of the road, the presence of a crash barrier and embankment on the roadside, the outcome of a roadside collision can lead to serious injuries and even deaths.The aim of this project is to investigate the possibility of improving road safety by designing the optimal roadside area based on the results of a life cycle cost analysis (LCC).The questions that have been answered during the duration of this project are:1) Describe the current technical solutions for roadside area design and the various barrier types used in Sweden.2) Complete an existing mathematical model that has been developed by Hawzheen Karim, for calculating life-cycle costs for various roadside areas.3) Calculate and compare the life cycle costs for the side area with a barrier and without a barrier.By performing an analysis of the documentation on the current guidelines and rules for shaping the roadside, was it possible to describe the current technical solutions for the formation the roadside as well as the current roadside barriers in use today. A mathematical model for calculating the life cycle costs of different barrier types had already been developed by Hawzheen Karim. This model was supplemented so that it could calculate life-cycle costs of the roadside region with and without a barrier. After the model was completed, an analysis was performed to obtain life-cycle costs of a roadside with and without a barrier.The result showed that there is a clear relationship between the slope inclination, fill height, and the rate at which the costs rise.

This thesis is a case study of the search function on the University of Uppsala?s web site. The search function in this study was chosen since it exists on a large and complex web site and there were apparent lacks in the old version of the search function. The thesis highlights some of the problems that can appear in the development of a search function on a local site. One interesting find is that one of the most difficult issues is organizational and not technical.

Husaberg Scandinavia AB is a company producing and developing a range of motorcycles for both on- and off-road use. Husaberg provided the project group with a task of developing an entirely new way of operating the sequential transmission that can be found in today?s motorcycles. The target was to bring the product from idea to a functional prototype ready for further tests. Operation of the motorcycles transmission is today made by a foot pedal placed on the left hand side of the bike.

The Swedish government have a goal that wind turbines shall produce 30 TWh by the year 2020, compared to about 3,5 TWh produced in Sweden during 2010. To minimize the disturbance that wind turbines create the Swedish Environmental Protection Agency has stated a guideline value that noise from wind turbines at nearby residents shouldn?t exceed 40 dBA, at 8 m/s wind speed. With advanced calculation models, like Nord 2000, the emitted sound from future wind turbines can be calculated at an early stage to optimize the power production without exceeding the 40 dBA. When the turbines have been built there is a need to verify that they really are within the guideline.

SMTP, the current protocol for sending electronic mail (e-mail) over the Internet, has for many years suffered from several problems and limitations. When it was designed, well over twenty years ago, the requirements for e-mail were very different from those of today. A message was a text message in English, and both user and machine were explicitly named in the address. The protocol was not designed to transfer other types of messages, and no mechanism was included to verify the identity of the sender.In order to solve these shortcomings, a new e-mail protocol needs to be defined. This report specifies a basis for what such a protocol may look like.

Preschool has a long tradition of using picture books, both as entertainment and as a resource for educational activities. In science there are two main application areas. The first one is science concepts and the second is to teach basic science process skills. These skills, observing, communicating, inferring, classifying, measuring and predicting reflects the methods used by scientists. Picture books potential to put science concepts and activities that promote the use of science process skills in a meaningful context, recommends using picture books for this purpose.

The digital era has led to technical advances that have transformed the role of the public library from being a place that is used only through physical visits and material, into also being a virtual space that can be accessed by users from outside the library through Internet-based access to e-media such as e-books and streamed or downloadable audiobooks.The aim of this study is to examine how the role of public libraries in Stockholm County has changed in the process of developing into digital libraries: how this has affected their organisation, work methods and strate- gies, as well as their accessibility. The theoretical framework of the study draws on Michael K. Bucklands theory of information accessibility, which is based on six factors of access that are determined by different types of barriers. The methodology is based on a combination of quantitative and qualitative methods. Primary data was gathered through an empirical survey, which consisted of a structured questionnaire distributed to most of the public libraries in Stockholm County and semi-structured interviews with selected librarians and experts for further in-depth understanding.
