Människovana grävlingar som testdjur för grythundar. En studie om hur grävlingars beteende och fysiologi påverkas av hundars aggressivitet
In Sweden live badgers are used in tests in order to train and prepare earth dogs for hunting underneath ground. This has for several years causeddebate concerning the welfare of the badgers. It is questioned whether the purpose of the dog training, i.e. to reduce injuries in both dogs and prey, is worth the suffering that is reflected on the badgers. The aim of this investigation was to study 1) stress levels in badgers when used in earth dog training, 2) if the stress load differs when the badgers are exposed to dogs with varying aggression levels (low, moderate, high).
Internetspråk : En studie i högstadieelevers språk på internet
In this essay we describe the characteristics of the internet language used by senior-level school pupils. Our primary question formulation is: ?Which are the significant features of the youth?s internet language on a morphological, lexical, syntactical and orthographical level?? In order to answer this question we have analyzed 45 text ex-amples which is brought from two different internet forums, Bilddagboken.se and Un-gdomar.se, forums which are widely used by youths. The analysis has been made on a morphological, lexical, orthographical and syntactical level. We have also another question formulation which is: ?How is emoticons used in youth?s internet conversa-tions?? Thereby we also study the use of emoticons in the examples we have analyzed.Our conclusion in this essay is that the youth?s internet language is a language that in many cases should be seen as an own language; it should be seen as an entirely new and unique way of communication.
Utmattning av vägbroar i armerad betong enligt eurokoder
Since 1 January 2010 it is a requirement to use the European standards, Eurocodes, in Sweden when constructing bridges. One chapter that has caused an extra amount of problems for the engineers is the one about fatigue analysis, which resulted in us doing this thesis.To do this we had to read all of the Eurocodes that direct, or indirect deals with fatigue and calculating of such. We have read the background documents for the Eurocodes and master?s thesis in the subject. We also studied the calculations of bridges constructed by different construction firms.We have chosen to limit the thesis to discuss only road bridges made of concrete due to the lack of method for verification of concrete in the national appendix.

Energieffektivisering av bostäder : En analys av åtgärder som kan förbättra energiprestandan i flerbostadshus
Efficient energy use in the housing sector is crucial for achieving a sustainable society. The expansion of this sector only represents a fraction of the existing houses, hence it?s within the existing houses the potential for energy savings lie. This potential has been analyzed in order to determine if it?s possible to cut the current energy demand in half.
Deduplicerings påverkan på effektförbrukningen : en studie av deduplicering i ZFS
Uppsatsen beskriver arbetet och undersökning för hur deduplicering i filsystemet ZFS påverkar effektförbrukningen. En större mängd redundant data förekommer i centraliserade lagringssystem som förser virtualiserade servrar med lagringsutrymme. Deduplicering kan för den typen av lagringsmiljö eliminera redundant data och ger en stor besparing av lagringsutrymme. Frågan som undersökningen avsåg att besvara var hur ett lagringssystem påverkas av det extra arbete som det innebär att deduplicera data i realtid.Metoden för att undersöka problemet var att utföra fem experiment med olika typer av scenarion. Varje scenario innebar att filer kopierades till ett lagringssystem med eller utan deduplicering för att senare kunna analysera skillnaden.

Isolerande och skyddande dubbelväv - Produktutveckling av ett kylande fodral
Denna rapport beskriver en produktutvecklingsprocess som behandlar utvecklandet av ett textilt material som isolerar och skyddar. Det textila materialet ska fungera till ett kylande fodral utan att förstöra dess funktion och behöver därför uppfylla en speciell kravspecifikation. Materialet ska isolera mot kroppsvärme, vara stabilt, skyddande och slitstarkt. Dubbelväv valdes tidigt i arbetet då det är ett enkelt sätt att kunna påverka det textila materialets egenskaper i form av material- och konstruktionsval, i en betydligt större utsträckning än i en enkelsidig väv. För att utveckla ett material med de efterfrågade egenskaperna har tester utförs och den metod som har använts är hypotesprövning.
PSQS ? Power Supply Quality Simulator
Kitron had wishes to be able to test and measure how disturbance affects their vehicle electronic units before they have been verified by SP Technical Research Institute of Sweden in Borås. This work started with the writing of a demand specification together with Kitron for a product PSQS, Power Supply Quality Simulator, which can generate some test pulses according to a standard for electronic units to Volvos vehicles. A design proposal was developed with the help the demand specification and was verified with the help of simulations. All electric schematics was designed with the guide of the design proposal. The pulses realized in the works of this thesis are those which Kitron experienced that they have a need to test in their own premises and which are possible to generate with the means available.
Ergonomiska förhållanden för mjölkare i olika mjölkstallar :
Earlier studies of musculoskeletal problems with milkers working in milking parlour
operators have shown that it is a physically demanding occupation. The extremities that are
most exposed are neck, shoulders, hands and wrists. Those systems that have been studied in
present cases are fishbone and some tandem barns.
There have been changes in the working environment during the past ten years. The
mechanisation has been developed for the better with automatically removers of the milking
units and vertically adjustable floors in almost every daily milking barn. In other hand the
milk production are more industrialised and more related to stress today.
