Base stations for communication in obstructed environments

The purpose of this project was to produce signal relay stations that could receive information via 2.4 GHz radio and relay the information to a designated target station. If a relay station was located outside of signal range for the target station it was supposed to utilize other relay stations to transfer the information to the target station, so called multi-hop.The would-be application of the relay stations was orienteering. When an orienteer punches a checkpoint the signal stations would relay information of who punched the control, when it was punched and the checkpoint that was punched to the speaker tower in the goal area.The work resulted in prototypes which fulfilled the statement of purpose and was tested at an orienteering competition with satisfactory results. The performance of the prototypes was tested and found adequate for the would-be application..

The petrol station ? a hot spot along the road

The increased travelling of today makes nodes along travelling routes more and more important. This is very much the case of petrol stations. They constitute important nodes in the road network, filling up thirsty fuel tanks and hungry stomachs, guiding road users and providing vehicle-services. In this thesis the role of the petrol station for road users was investigated in order to find out if the petrol station was a potential hot spot. We performed an ethnographic field study at a petrol station and found that a great number of visitor activities took place at the petrol station.

Webbradion : ett nytt medium

The purpose of this essay is to study the role of web radio in Sweden. To fulfill the purpose we have done a case study of two Swedish radio stations: Sveriges Radio AB, which is a public service station, and a commercial station called Mix Megapol. By interviewing two persons from each station and analyzing the contents of their web sites, we have tried to see how the relationship between radio, Internet and web radio looks like. Thus, our method is qualitative. We have come to many conclusion of which some are: The new medium web radio borrows qualities from the traditional radio.

Från föhn till feu! : Esrange och den norrländska rymdverksamhetens tillkomsthistoria från sekelskiftet 1900 till 1966

This essay is about the origin, planning and establishment of the European Space Research Organisation's (ESRO) sounding rocket base Esrange outside Kiruna in Northern Sweden. Three main questions are examined. First I show there were not just scientific and technical but also political, economical as well as military reasons to build a European rocket base. Second, I scrutinize the reasons to choose Northern Sweden as the location for the rocket base. As it turns out, the main reasons were the favourable location of Northern Sweden within the aurora oval zone, the proximity of the Kiruna Geophysical Observatory, and the possibility to use a large, although not quite uninhabited, area where the launched rockets could crash.

Konsten under jorden : En analys av Ulrik Samuelsons konst i Kungsträdgårdens tunnelbanestation

This study examines the work of art in the underground station Kungsträdgården in Stockholm and discusses the observers interpretation of the art in the station. When the artist Ulrik Samuelson got his commission to shape the station he was influenced by Marcel Duchamp and the concept art. Two themes were integrated in the work of art, the actual culture life and the palace called Makalös, which was situated just above the currant station, three hundred years ago. The station was built in two stages.The first part was opened in 1977 and the second part in 1987. Panofsky´s iconographic working method has been used in this essay.

Forskningsområdet biblioteks- och informationsvetenskap vid Högskolan i Borås ? En bibliometrisk studie av den intellektuella basen 2001?2006

The aim of this study was to map the intellectual base at the Swedish School of Library and Information Science (SSLIS) at the University Collage of Borås, and to compare this intellectual base to the intellectual base of the research area Library and Information Science. This was done by analysing the citations in publications published, between the year of 2001 to the first quarter of 2006, by researchers at the institution, using the technique of author cocitation analysis. Cluster analysis and multidimensional scaling, statistical techniques that are traditional i the author cocitation analysis, formed an objective map of the intellectual base at the SSLIS. This map was then compared with three prior studies, that used the same technique to map the intellectual base of the research area. The result shows that the map of the intellectual base at the SSLIS consists of the specialities: user studies, library studies, culture/cultural policy, information retrieval, bibliometrics and information in organisations.

Uppbyggnad och reglering av en pumpstation till ett injektionssystem

I was assigned to the thesis as part of a project GMA AB (Ground Machinery Applications AB) is running. The project aims to develop a new method for injection of drilled holes in rock walls. Currently, the injections usually involve cement but the basic idea of the project is to replace cement with a supplement called Silica sol.Silica sol is known as a gelling liquid. The gel time is controlled by a mixing of saline. Depending on the amount saline that gets mixed in, the gel time varies.

Kraftfoderstation till hästar : äter hästen grovfoder eller halm efter konsumtion av små kraftfodergivor?

The German equine housing system, HIT Active Stable?, are adjusted for keeping horses in groups, and are well establishes in Germany. Now the system attracts attention here in Sweden. The purpose of this study was to investigate if the horses have any be-haviours need of free access to roughages like straw or hay, after they have been visit the concentrate feeding station. A study was carried out at family Krohn?s active stables in Bönningstedt, Germany.

Ränteavdragsbegränsningsreglerna : Är den svenska skattebasen skyddad?

This thesis treats the extended Swedish rules regarding deduction limitations on interest. The purpose for this thesis is to investigate whether the interest deduction limitation rules have potential to protect the Swedish tax base. The thesis also assesses whether the options presented how the extended rules could look liked had been better to protect the Swedish tax base. Furthermore thin capitalizations rules have been evaluated if this is a better method to protect the Swedish tax base.In 2009 the Swedish deduction limitations rules on interest came in to force to protect the Swedish tax base. Despite these rules companies was still able to avoid Swedish tax and therefore threatened the Swedish tax base.

Batterilyft för telekom basstationer

The purpose with this thesis work was to design and build a technical aid for installingbatteries in telecom base stations. Today that job is done manually, since there is noequipment on the market for that purpose. Installing batteries in base stations manually isa very tough job.To get ideas for possible solutions a preliminary study on existing lift aids was done.From the preliminary study the conclusion that some kind of overhead crane would besuitable for the task was drawn. After that a lift for installing batteries in base stationswas designed, built and tested. The tests show that it is possible to minimize heavy liftingwhen installing batteries in telecom base stations, at a relatively low cost.ii.

Syra-bas och laktat hos kolikhästar :

Ten colic horses and seven healthy horses were included in a prospective study aiming to evaluate acid-base disturbances in colic horses. Traditional acid-base methods and measurements of lactate were used to study prognosis and changes before, during and after surgery. Strong ion gap, anion gap and base excess were compared to evaluate their ability to predict lactate. Of the ten colic horses that went through surgery, seven survived, two were euthanised and one died. Significant differences in plasma lactate levels were seen between the group of survivals and non-survivals, p=0,000025. No differences were seen in pH and base excess between the two groups.

Testramverk för distribuerade system

When developing software that is meant to be distributed over several different computers and several different networks while still working together against a common goal there is a challenge in testing how updates within a single component will affect the system as a whole. Even if the performance of that specific component increases that is no guarantee for the increased performance of the entire system. Traditional methods of testing software becomes both hard and tedious when several different machines has to be involved for a single test and all of those machines has to be synchronized as well.This thesis has resulted in an exemplary application suite for testing distributed software. The thesis describes the method used for implementation as well as a description of the actual application suite that was developed. During the development several important factors and improvements for such a system was identified, which are described at the end of the thesis even though some of them never made it into the actual implementation.
