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.

Utvärdering av Trafikverkets åtgärdsförslag för personpåkörningar, suicid och plankorsningsolyckor på järnvägen i Region Väst
106 personer omkom eller skadades allvarligt under 2011 på järnvägen i Sverige. Trafikverket jobbar ständigt med att förbättra säkerheten både inom och på järnvägen, allt i enighet med deras vision som lyder, Målet för säkerhet inom järnvägstransportområdet är att antalet omkomna och allvarligt skadade inom järnvägstranssportområdet fortlöpande ska minska.Trafikverket är en statlig myndighet i Sverige som ansvarar för långsiktig planering av infrastrukturen samt för byggande, drift och underhåll av de statliga vägarna och järnvägarna. De är också skyldiga att utreda alla olyckor som sker på järnvägen och komma med åtgärdsförslag så att liknande olyckor inte sker i framtiden.Den här rapportens huvudsyfte var att granska och följa upp de åtgärdsförslag av fysisk karaktär som Trafikverkets olycksutredare har angivit i sina utredningsrapporter och se vilka åtgärder av dessa som blivit genomförda. Rapporten behandlar olyckstyperna personpåkörningar, suicid samt plankorsningsolyckor i Region Väst, som består av Hallands, Västra Götalands och Värmlands län. Tidsperioden för olyckorna är 2005-01-01 till 2012-05-31.
Nybyggnad till fårproduktion :
In Sweden we need more lambs during March to June. I decided to calculate on a spring lamb
production, because to many of the Swedish lambs go to slaughter in the autumn. I counted on
1000 ewes which have 2000 lambs each year, 200 of these lambs stays on the farm and
replace old ewes. The buildings are 3600 square meters. I have counted on two different sorts
of buildings, the first one is a shed, the second one is three polytunnel sheephouses.
Kvalitetssäkring och processtyrningav ytstruktur på lackerat objekt
To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..

Entreprenörskap på landsbygden : 6 små livsmedelsförädlande företag i Mälardalen
For a long time, economic activity has decreased and shows a downward trend in the food sector. To break this requires efforts to strengthen corporate position with the ability to meet market challenges.
In the small producers is a great potential for them to be able to increase its profitability thanks to its ability to offer added value in the product. But to achieve this requires not only a willingness and creativity out of the ordinary but also factors that lead us into this report, current issues. The issues are related to marketing, brand building and the importance of developing a stable network.
The study aims to investigate how small businesses operate in rural areas are experiencing the possibilities of support from various networks and organizations and that, from a business perspective, and also see which areas that they need more support in to achieve a growing business. The work has been followed by an inductive method, when we initially could not say anything about the empirical results.
Uppföljning av lokförare på SJ och Green Cargo i Region Västra Sverige, med beviljad dispens från hälsoföreskrifterna, avseende ev. olyckor eller olyckstillbud
Järnvägstrafiken i Sverige drivs idag huvudsakligen av SJ (Statens Järnvägar), som ansvarar för persontrafik och GreenCargo, som ansvarar för godstrafiken.Banverket ansvarar för säkerhetsuppföljning av den spårbundna trafiken i Sverige. Avsevärda tekniska förbättringar har lett till betydande ökad säkerhet sista 15 åren. Lok-/tågförare arbetar under särskilda medicinska säkerhetskrav, reglerade enligt järnvägslagen (2004:19) och i Järnvägsinspektionens föreskrifter( BV-FS 2004:4). Dispens från vissa av dessa säkerhetskrav kan emellertid beviljas vid en del handikapp eller sjukdomar. Företagshälsovården har en del av ansvaret för uppföljningar och bedömningar i detta sammanhang.
Samverkan kring arbetsrehabilitering : En kvalitativ studie av ett projekt
ABSTRACTThe purpose of our study was to examine how four different organizations cooperate on rehabilitation of people to get them back to employment. More specifically our aim was to investigate how different organizations in a project, involving workrehabilitation, looks at cooperation. Our main questions were vague at the beginning of our study, but finally our focus became clear. The questions were formed with help from the research of Hjortsjö (2006) and Fridolf (2000): Which possibilities and hindrances identify the different organizations which cooperate? What does cooperation mean to the representatives from the different organizations which are included in KARB? Our result shows that the respondents mostly think positive of the project KARB.
Ryttarens tygelsignalers inverkan på hästens beteende och trycket i tyglarna
This essay derives from the concern that horses ridden with a bit in their mouth can be subjected to strong pressure from the bit if the horse and rider do not understand each other. The horse's mucosa membrane and the tongue are very sensitive tissues (Cook, 1999; Manfredi, 2005; Oliveira, 2005; Terada, 2006) and the bit can then be a source of pain and discomfort. The training of the horse should therefore always be a step by step process and as the horse develops difficulties are increased. Oliveira (2005) suggested that high demands can be placed on the horse but to be successful in the training it is essential to be content with small progress and reward the slightest desired response from the horse. This corresponds with the principles of operant conditioning with negative reinforcement.

This report is the concluding part of the course national minorities, main focus on design, at Luleå University of Technology spring 2007. The purpose of this written examination is to produce a prototype to a product, which can be used both when marketing Kiruna as a student municipality and when recruiting students to the study programmes Kiruna offers. The product has been produced through systematic problem solving, where methods to fix the problem, gather facts, examine and come to a solution have been used. The product should in one way or another get the student to think of Kiruna as a student municipality and it should also appeal to the target group ? the students.
Två tidningsvärldar vid Öresund. Sydsvenskan och Berlingske Tidende - en komparativ analys.
Öresundsregionen är idag en region i förändring. De senaste åren har danska och svenska medborgare börjat arbeta, bo eller på annat sätt vistas på andra sidan sundet i allt högre grad. Tillväxten är hög och Malmö och Köpenhamn integreras på ett sätt som är ovanligt för städer lokaliserade i olika länder. År 2004 bosatte sig fyra gånger så många danskar i Skåne som under 1998 vilket innebär en ökning från 800 till 3 200 personer per respektive år. Antalet pendlare som bor i Skåne och var dag åker över bron för att arbeta i Danmark har enligt en artikel i Dagens Nyheter ökat med 40 procent det senaste året och enligt samma tidning förväntas den totala pendlingen över bron om 10 år vara dubbelt så stor om som idag.
