The task in this master thesis was to design and construct a prototype of a satellite antenna driver unit. The unit is to be robust and work in cold weather down to -40°C, so that it can be mounted on the roof of a minibus. A microcontroller controls the H-bridges simultaneous, each connected to an electrical motor. Hardware and software protections were implemented to ensure that the antenna can not turn outside its allowed area and risk breaking. The unit can output voltages at many different levels and communicate at a multitude of signal standards..

Abstract This degree project examines how much carbon dioxide that emits during the construction phase of a road project. This is to make it possible to compare how the amount of carbon dioxide differentiates between traditional road construction and Swepave construction, which is PEAB?s alternative way to design roads. To make the comparison a calculation tool has been produced. To compare the amount of carbon dioxide emissions a reference project was needed.

The purpose of this project is to get a fully functional, automatic steering system and a variable breaking system with an emergency breaking function to an off road vehicle. This off road vehicle is supposed to work as an aid in military situations. A team of two, Sebastian Attervall and Nichlas Gustafsson, got an order from Jonas Nyårds and the PreeRunners Project to construct a steering system that could manoeuvre an off road vehicle without any human involvement. To make this possible the vehicle would be guided by onboard sensors, cameras and computers. The team where also assigned to construct an automatic breaking system, there also no human would be involved.

In 2006, Stora Enso Skog implemented an education program in water management for harvester operators, timber purchasers, cut block planners and supervisors. The focus of the program was creating stream crossings with minimal harm to the stream and the surrounding riparian area. This main purpose of this study was to determine the difference in work procedures before and after participating in the program. The methodology consisted of field studies and interviews with harvester operators and their supervisors. The field study looked at how the streams had been crossed concerning the number of crossings, visible damage to the stream and/or the riparian area made by the machines. Biological parameters such as the width and dept of the stream and amount of large woody debris in the stream were also measured. The field result from 30 harvesting sites showed no significant difference between sites that had been harvested before or after the education program. But the harvester operators and their supervisors experienced an increased concern for watersheds after the educational program.

A high quality is highly requested in today?s thinnings, since these are the base for continued value development of the forests. Thinning quality often means a minimization of damages on soil, stems and roots during the cutting. One way to reach a high quality is to set up goals that will be followed up after the cutting is made. Self-checking gives information of the machine drivers work and guarantees the customers a good quality of work.

The purpose of this study was to, through the life stories of four women and their experiences, thoughts and feelings according to a life in drug dependency reach an increased knowledge about how a dependency can arise, continue and be brought to an end. The question at issue were: How do a small amount of women describe and comprehend their experiences, thoughts and feelings according to their drug addiction seen through a process perspective. In order to answer that question three themes were investigated: the road into dependency, living as an addict and the road to recovery from dependency and the time that follows. The study followed a qualitative method and the theoretical approach was hermeneutic. The results were analysed through a process analyse perspective, from the view of the chosen theoretical perspectives, social constructivism, experience perspective and a psychodynamic perspective.

Abandoned and unused railway structures often possess great potential if they are reclaimed and reused for new purposes. The thesis focuses on the global trend of restoring and revitalizing these areas, converting them into park areas, rail trails and green corridors in the city landscape, while preserving their ecological, social, esthetic and historic values. These rail areas were often abandoned when industries moved out from the cities, either to industrial areas or abroad. The use of railways for transporting industrial goods was also replaced to a large extent my motorized road vehicles in the mid 20th century, leaving the rails under-utilized. Because of their location and intrinsic values, they can be reused for important functions, such as green areas in the city environment, providing space for recreational activities and exercise and social meetings and interactions. I have closely investigated the three park areas High Line in New York, Promenade Plantée in Paris and Schöneberger Südgelände in Berlin, which have all gone through this transformation in recent years. I have summarized my conclusions in three key concepts to consider: design for social values, preserve the architectural history, and leave room for future evolution. The final part of my work is a design program for an abandoned railways area in Stockholm: Eriksdal railway area.

When designing roads it?s important to knowwhat loads will bedriven on it. The axles on heavy vehicles can either have super single tires ordual tires which, according to studies, damage the roads differently. The SwedishTransport Administration is developing an understanding for the character ofthese different kinds of axle and tire types on the loads induced on Swedishroads. In this thesis a field study was conducted to determine the distributionbetween axles with super single tires and axles with dual tires on heavy vehicles.A highway, a country road and a national road were investigated during thestudy.

Outside of many Swedish households today, you will find a typical green wastecontainer. This container has not changed since its introduction, despitecomplaints about foul-smelling and its impractical system. Even if the system usedtoday, still is the most optimal choice, there is a lot of newly developedalternatives out there.Its purpose is to get a broader perspective on how a waste management systemcan be developed into a working, land efficiently and aesthetically pleasing systemof humans and the environment in a small residential area.The authors treat the residential area of Jära, Ekhagen, in Jönköping, which ismanaged by JM AB as a problem area in regards to waste management.The issues raised by the authors are the different waste management systems usedin the corresponding areas of the world, how to apply technical andenvironmental as well as the waste management facilities from financial aspects.In the process, the methods used were literature reviews, case studies and aninterview. The case study was done through a modeling of waste managementsystems in the area Jära and an interview was conducted with the company Envacworking with vacuum systems. Studies have been made by different systems n theareas around the world.The results show that using directives and guidance will reduce the environmentalimpact done without replacing the traditional system.

Road transports stand for a great part of Sweden?s total CO2-emissions. Transports are expected to increase over the coming years, and with those the emissions. A greater environmental awareness leads to increased demands for environmentally friendly transport. The aim of this thesis is to study the consequences of changing transportation modes from road to railway.

Water hardness indicates the concentration of calcium and magnesium ions in water. Water with high concentrations of these ions is described as hard water and water with low concentrations is described as soft water. Water that is too hard or too soft can lead to technical and economical problems. In collaboration with Midvatten AB, groundwater hardness in the Badelunda esker between Leksand and Avesta has been mapped, and an attempt has been made to explain the variations. For this purpose, different GIS programs, such as ArcView, ArcInfo, IDIRISI, and one geochemical modelling program, PHREEQC, has been used.

This paper deals with U 150, a rune-stone raised by Jarlabanke, a wealthy man who lived in the 11th century. He raised about 7 rune-stones telling us that he made bridges, roads and was the owner of the whole of Täby. U 150 is carved with ornaments that seem to be a lot older than the other ornaments of the Jarlabanke stones that Jarlabanke raised for himself, while he still was alive.  It is argued that the rune-stone U 150 was in fact made by another man called Jarl Banke (not Jarlabanke), who was a Jarl in the 11th century and is mentioned on at least three rune-stones in the same area as the Jarlabanke rune-stones..

Title:?Speed cameras - an prevention of crime and a standard forming instrument of control??Authors: Markus HanssonTutors: Bo Isenberg & Carl HultExaminator: Ulf DruggeThe School of Human SciencesUniversity of KalmarThe studys purpose is to get a absorbed understanding for peoples attitude, and effect of speed cameras. The disposition for the study is to integrate earlier studies in the matter, combined with elevating interesting sociological conceptions. As an attempt to understand speed cameras as an instrument of force on the individual have Michel Foucaults concept Panopticon been used to see its effect, and it?s look upon how crime prevention will be formulated, which can give an explanation of why speed cameras are being used as an instrument of control on the traffic area.
