GIS-program för ruttplanering. En studie av nyttjandet av GIS-program för ruttplanering inom tekniska förvaltningar bland kommunder i västra Sverige
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.
Beräkning av värmeförluster och energieffektivisering av elbussar
The ?civilized? world is in need of fossil fuel in order to function. Hybricon AB is a company in Umeå that is developing a technology that hopefully can reduce parts of this need. They are currently testing their two electrical busses (with Hybrid backup) in city traffic on the roads of Umeå in cooperation with the county of Umeå. The busses are originally diesel-busses, but the diesel motor has been replaced with two electrical hub-motors with a power of 145 kW each that are powered by batteries.The batteries are charged at the end station after each route. In case the batteries should run low on capacity during driving, they can be recharged by the so called genset.

Den sociala dimensionen av EU-medborgarskapet
Since the introduction of the European citizenship in the Maastricht treaty, social rights havetaken a back seat to the economic and political elements. Nevertheless, over the past yearssocial issues have been increasingly included on the agenda following the universalrecognition of challenges resulting from further economic integration and demographicchange. The extensive research on European social policy so far tend to focus on initiativesput forward by the European Commission, and offers little to explain the multitude of lines ofreasoning on how far EU social policy should be taken or why it still remains one of the leastdeveloped policy areas. By examining plenary debates in the European Parliament concerningfamily policy, this Bachelor thesis aims to describe the complex of problems connected to afurther development of the social dimension of the European citizenship.The analysis finds that the most imminent problems impeding an expansion of the EU familypolicy lie not only in the many clashes of opinions between advocates of the various existingwelfare models, but also in the conflicts of interests and the different levels of ambitionbetween EU institutions - most notably the Commission and the European Parliament..
Back to the USSR : En studie av Rysslands demokratiska urholkning
Abstract:The purpose of this study is to examine what actually makes Russia an incomplete democracy, despite of all the formal democratic institutions and legal democratic rights.The research method used for this essay has been qualitative case study, which strives to answer two research questions: Which democratic principles are not respected in Russia? How does the executive power control the political arena? The theoretical framework used for this study consists of a model based on Dahls Polyarchy theory and the Rule of Law concept. The conclusions points out that very little have formally changed in Russia regarding democratic rights and the constitution. The democratic decline is due to political manoeuvres and undue political influence. There is no proper division of power and the executive powers are not controlled by a system of checks and balances.
Vems är det svenska kulturarvet? : En diskursanalys av Riksantikvariatets kulturarvs- och identitetsproduktion
This thesis examines the National Heritage Board in Sweden and the way they look upon themselves, the surrounding world and their mission. Methodologically it?s a discourse analysis based on poststructuralist and social constructionist thoughts. This means, simplified, that nothing is taken for granted and that power relations and ideology always matters. There is no true or distinct heritage.
Kundrelationer på menyn : ? En fallstudie av McDonalds erbjudande och kunders beteende för skapandet av långsiktiga relationer.
The study aims to understand the underlying factor why McDonald's customers return despiteprevious failure customer experiences. Why do customers come back to the company thatcontributes to the former dissatisfaction? McDonald's attempt to maintain unceasingpurposeful emergence fail at the local level, where the customer contact occurs. McDonald'sofferings and customers' bounded rationality results in that customers are satisfied with an"ok" experience, which adds to their low expectations of McDonalds. This makes clear thatMcDonald's does not have to make an effort through constant adaptation at the local level toachieve a "great" level of satisfaction.
Debatten om det kommunala självstyret 1978 och 1998. En analys av en tillsynes odödlig debatt.
In this essay I will look at the independence of the Swedish municipalities. By looking at articles for the biggest journal in Sweden on this subject Kommun aktuellt I will look at the discussion for the years of 1978 and 1998 to see if one can draw some parallels in the debate and see if some subjects are always returning in the agenda for the independence. The autonomy of the Swedish municipalities is a very important part of the Swedish welfare model. The municipalities handles for example both the primary schools and the social welfare services. Both these institutions are money draining and the municipals right by law to claim local tax does far from all the time cover its expenses.
Förhandling av kärnvapennedrustningsfördrag : En jämförande studie av CTBT och FMCT
AbstractThis essay discusses the negotiation of the Comprehensive Test Ban Treaty (CTBT) and the process that led up to a signed agreement. The CTBT forbids all nuclear weapon test explosions and all other types of nuclear explosions. The purpose of the study was to distinguish the critical steps of the negotiations that resulted in the success of the CTBT. Based on these insights, my intention was to identify relevant events and actors in the process around the Fissile Material Cut-off Treaty (FMCT), which has been on the nuclear disarmament agenda for over a decade. Furthermore, my ambition was that the examination of the CTBT negotiation would give me some clarity in what the next step would be to get the FMCT back on track.
Vågkraft : Olika möjligheter med vågkraft
Idag består största delen av vår energikonsumtion av fossila bränslen, vilka leder till en rad olika miljöproblem varför det är viktigt att ta fram alternativ. Vågkraft har en stor potential till att bli en energikälla med väsentlig betydelse för framtida elproduktion. Syftet med undersök-ningen har varit att studera olika möjligheter som vågkraftsindustrin har att erbjuda och att se vilka tekniska lösningar som förväntas bli dominerande inom de närmaste 20 åren. Genom vågenergiomvandlare omvandlas vågornas energi till elektricitet och det är energiomvand-lingen som kallas för vågkraft. Det finns många olika platser i världen som lämpar sig för vågkraft, framför allt länder med kust mot Atlanten och Stilla havet.
Ekonomin i syrning av spannmål till mjölkkor :
In this dissertation I have tried to figure out if it possible to make any money on acid grain to feed cows through a case study. The method is a case study combined with a documentary research. At present the farm sell all grain in connection with harvest and buy it back continuously in the neighbourhood, I have compared that with an alternative where I invest in a construction for to store acid grain on the current farm.
I have delimit me to only have a look on acid grain because I think that is one of the cheapest way too store grain in smaller aplenty. Before beginning with acid grain is it important to be versed in how everything works and the risk to keep on with acid grain.
One disadvantage is that the acid grain is not possible to store more than 12 months with out acid it once again. It is also easy to get mould in the pasture if it is not acid enough.

Upplevda oönskade beteenden hos katt : förekomst och orsaker till dessa
The objective was to examine the frequency of unwanted behaviors in the Swedish feline population and what factors in the environment, inheritance and past life that have an influence on the frequency. SLU?s web poll generator was used to create a web poll which insinuated that it was a poll with objective to make an inventory of the Swedish feline population. I wanted to avoid that only owners to cats with unwanted behaviors answered the poll. The web link to the poll was sent to SLUs students and posted on Internet forums for people interested in cats.
