Syftet med denna uppsats var att undersöka vilka faktorer som påverkar hur förvärvsarbetande människor i Gävle använder sig av bil och aktiv transport när de transporterar sig till destinationer inom staden. Tio personer, fem butiksbiträden och fem lärare, intervjuades angående deras transportvanor och resonemang kring valet av transportsätt.Resultatet visade att aktiv transport var det vanligaste transportsättet till arbete, träning och butiker i centrum medan bilen var det vanligaste transportsättet till mataffären och destinationer på längre avstånd från hemmet. Avståndet till destinationen, tiden det tar att transportera sig, transport av eventuella varor, bekvämlighet, intresse av motion och rekreation, årstid, väder samt synen på ekonomi och miljö var faktorer som påverkade om deltagarna valde att transportera sig med bil eller aktiv transport. Definitionen på de olika faktorerna varierade mellan deltagarna, vilket kan tyda på att det är den personliga uppfattningen om de olika faktorerna som avgör vilket transportsätt som väljs. Det framkom ingen märkbar skillnad i resvanor mellan deltagare med olika utbildning och arbete..

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..

In Sweden, the demand for bio energy has increased in recent years due to the current energy and climate debate. In 2008, the energy supply of Sweden was 612 TWh, biofuels accounted for 123 TWh of these. Stumps have been highlighted as a potential fuel in recent years and the Swedish Forest Agency expects a technically and biologically feasible potential of 20.7 TWh annually between 2010 and 2019. The idea of utilize stumps is not new. During the 19th century stumps were used for tar production and during the 70?s and 80?s attempts were made to use stumps in the pulp industry.

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.

Modern air battles are very dynamic and fast, and put extreme pressure on pilots. In some unpredictable situations, like new discovered threats or mission plan deviation because of enemy aircraft, the pilots might need to replan their predefined flight route. This is very difficult, if not impossible, to do since numerous factors affect it. A system that can help the pilots to do such a thing is needed. Previous work in this field has involved methods from artificial intelligence like A*-search.

Biodiversity can be described as the total variation of life forms, where diversity ranges from gene level up to the ecosystem level. The diversity can be calculated in a number of ways, and this study use one of these methods. In this study empirical food webs have been used and analyzed, where eleven characters are defined and used as parameters to calculate the Euclidean distances between food webs that describe the variation that may exist within classes of terrestrial, marine and freshwater habitats. The class who stood out and showed the greatest diversity at the ecosystem level was the marine food webs, which showed a high value of the average euclidean distance. The other networks were not as distinctive and the average of the euclidean distance in these classes was comparatively low..

The purpose of this thesis is to investigate how students who study with Problem-based learning PBL in a distance learning course perceive the support from the university library. I first went into adult education, PBL and distance studies, one at a time, and then took a look at the combination of problem-based learning in distance studies. During the investigation, I conducted five interviews using a phenomenographic method to understand how the students perceived the support they received from the university library. The university library gives a lot of support but what I noticed while I was writing was that it is difficult to reach the students with the information regarding the help that is available to them. I give some example on how to develop the support and find that the students have a wide range of different needs for support from the library depending on their individual situation, social context, academic ability, location and course of study.

In 1997, the Swedish parliament adopted a decision on Vision Zero (nollvision) in the road and transport system. Vision Zero means that no one should be killed or seriously injured in traffic accidents in the road transport system (Prop. 2003/04: 160). For the Transport Administration in Sweden (Trafikverket), this means increased demands on security and signage at road work sites around the country. This in turn means increased demands on the contractors that carry out road work for the Transport Administration.

To study and laborate at distance, its necessary that the coursematerial is accessible via internet. Teaching at more languages than swedish bocomes more common, why the information of courses needs to exist at several languages. As teacher, you need a way to publish and edit material of a course. It also has to be easy for the students to find the information. The distance laboratory have developed an administrative websystem that handles programme, courses and students, but misses the possibility for teachers to change content at the webpages and publish new coursematerial on a way..

Under de senaste tio åren har antalet hästsportsevenemang ökat drastiskt, både internationellt och i Sverige. Det ökade antalet hästsportsevenemang visar på ett ökat intresse för hästsport och hästar vilket i sin tur föranlett en ökning i transport av häst. Vetenskaplig litteratur inom ämnet är knapp och det som finns berör vanligen fysiologiska mätningar för att uppmäta stress under transport. För att få en uppfattning om hur marktransporter av häst går till i Sverige och skapa en kunskapsbas för framtida studier utfördes en webbaserad enkätstudie. Enkäten låg ute i 6 dagar och 1013 personer svarade varav 906 stycken kunde analyseras.

Climate change has become an increasingly topical subject. Recently debate on how our food affects the environment has flared. It has been shown that how the food we eat is grown and transported could be one the bigger contributors to the emission of carbon dioxide into the atmosphere. The aim of this study is to see how consumer?s choices of vegetables affect release of carbon dioxide. The results show that emissions of carbon dioxide can be lowered by consuming vegetables that have been grown on open land. Vegetables that have to be grown in heated greenhouses in Sweden should perhaps be exchanged for such that have been grown in unheated greenhouses in southern Europe, even though the transport distance is significant. .

The aim of this thesis is to get a better understanding of how the management control system works at V&S Distillers. V&S Distillers went through an organizational change in the beginning of 2005. The marketing function went from being a country-driven to a category-driven organization. Among other things this resulted in increased cooperation between employees in different geographical locations. We aim to analyze how a geographical distance affects relations and the use of management control.

Abstract (in English)The purpose of this work is to find out what the driving instructor who currently works as a transport teachers feel about today´s driving education to transport high school to how it works at driving school. I describe in the study on how to become a transport teachers and on their everyday work. Even what others have written on this topic on driver training. I also interviewed four driving instructor who currently works as a transport teacher, about what they had for opinions on this issue. The method I have used myself of where unstructured questions to get so descriptive answers to questions as possible.

In this thesis a transport system is sought after thatif realised in the city of Uppsala could provide bothwell-being to all its inhabitants and sustainability,here jointly refered to as liveability. It is found thatthe car dominated transport system that is inoperation today provides two fundamental values,namely accessibility in both time and space, whichsets it apart from other transport solutions. Thesetwo values are of immense importance for theliveability in our modern world. On the other handthe car dominated system decreases the liveabilityof Uppsala in several different ways. Some of theseproblems, it is argued, could be solved within thecar system, through the adoption of moreenvironmentally friendly cars etc., but otherproblems are inherent in the car system and willremain no matter what changes are made.
