Lärk eller Impregnerat ? en kvalitativt jämförande livscykelanalys av sibirisk lärk och svensk tryckimpregnerad furu
This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

Kulturellt och psykiskt avstånd : En studie om EU:s inre marknad
Objective: The papers objective is to create a deeper understanding for whether or not cultural and psychic distance affects corporate establishments in the EU.Method: The results have been gathered through intense data collection through interviews with ScaniaAB and Business Sweden. There has also been extensive research of 36 different companies and their first establishments in different countries. We have then analyzed the results through cultural and psychic distance and through Uppsala University's internationalization process model.Conclusion: The conclusions of this paper are:Corporate establishment often occurs in neighboring countries because of the similarity to the domestic markets which contribute with a greater security.Since the introduction of the EU single market, corporate establishments have become easier within the single market.The cultural and psychic distance does exist within the EU, however the internal market decreases these distances and the impact on corporate establishments.The market commitment is essential to the corporates survival within the new market.Cultural and psychic distance affects small firms more often since their lack of network and experience.Cultural and psychic distances are two different but related phenomena..

"När katten är borta..." : En studie kring pedagogiskt ledarskap på distans
AbstractTitle: When the cat is away? A study of pedagogical leadership at a distanceLevel: Final assignment for Degree of Master of science (one year) in Educational ManagementAuthor: Evelyn JoelssonSupervisor: Ulla SebrantDate: 2013 mayLeadership is a subject that has been discussed for many generations. Today?s leadership is something completely different than what has been practiced before, in the more hierarchical companies, when leadership was something you were born to do and the workers had no choice but to follow. In the globalised world that we live in today there are demands of a different kind than before and physical distance between leaders and their followers gets more and more common.
Gage R&R studie på mätutrustning för förpackningsavstånd
The aim of the thesis is to analyse and understand resolution, repeatability and reproducibility of the measurement system for package distance. The measurement system for package distance is already in use, no Gage R&R has been performed on the system and before spreading use of the system the quality of the system has to be understood and approved.
Hållbar kapselåtervinningslösning
This thesis processes the work of developing CPU code and GPU code for Thomas Kaijsers algorithm for calculating the kantorovich distance and the performance between the two is compared. Initially there is a rundown of the algorithm which calculates the kantorovich distance between two images. Thereafter we go through the CPU implementation followed by GPGPU written in CUDA. Then the results are presented. Lastly, an analysis about the results and a discussion with possible improvements is presented for possible future applications..

Effects of Driver, Vehicle, and Environment Characteristics on Collision Warning System Design
The purpose of the present study was to examine effects of driver, vehicle, and environment characteristics on Collision Warning System (CWS) design. One hypothesis was made that the capability of collision avoidance would not be same among a driver, vehicle, and environment group with different characteristics. Accident analysis and quantitative analysis was used to examine this hypothesis in terms of ?risk? and ?safety margin? respectively. Rear-end collision had a stronger focus in the present study.
Excel-baserad beräkning och dokumentation av distansskyddsinställningar
This is a master thesis work carried out at the Department of Energy and Environment atthe Division of Electric Power Engineering. The master thesis work describes the theoryof distance protection relaying in 130 kV meshed distribution networks. The main aim ofthe thesis was to construct an Excel application for calculation and documentation of thesettings for distance protection relays. The program is based on general methods forcalculating settings of the different zones for the distance relay and presents the settingsin simple graphics using quadrilateral characteristics.The reason for building an Excel based application is the great variety of distanceprotection relays in live networks. The manufacturers of distance protection relays makeprogram for documentation available, however, they are based on the typical settings forthe specific relays.

Distansskogsägares nöjdhet med Södras tjänsteutbud och kvalité på tjänster
The development of technology and the mechanization in the Swedish forestry has during the last 60 years resulted in depopulation of the country side and due to that the amount of distance forest owners has increased. Therefore the forest companies need to make some adjustments in order to keep the distance forest owners as customers and to attract new ones. The purpose of this essay was to examine and analyze the distance forest owners satisfaction with Södras service offering and quality of service and further develop some proposals for action. A web-based survey was sent out to 634 distance forests owners in Stockholm, Sweden, all members of Södra. 269 respondents participated in the survey and of them, 27 did also participate in a follow-up telephone interview.
