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.

Betydelsen av social rang på beteende och mjölkningsparametrer i ett automatiskt mjölkningssystem (AMS) :
The purpose with the study was to find a pattern in the behaviour of dairy cows which could be related to their social rank. A behavioural study was conducted at the University Cattle Research Centre (Kungsängen) in Uppsala, Sweden. The study included 12 lactating dairy cows, 6 high ranked and 6 low ranked. The cows were housed in a loose housing barn with an automatic milking system (AMS) to which they had access 24 hours a day. During the experiment the total number of cows in the barn was 46.

Vad orsakar höga ammoniumvärden i ensilage? :
High levels of ammonia in grass silage have been up for discussion by Swedish advisers. One
reason is that it is more difficult for the rumen-microbes to utilise high levels of ammonia. A
low level of ammonia is also good because if the cattle can use more of the protein in the
silage, they don?t need so much protein concentrate. That is very good for the economy at the
farm, and it is also good for the environmental problems caused by high levels of ammonia.
In this project, 24 samples of silage have been taken at 20 different farms in the south west of
Sweden.
Bankers behov av redovisningsinformation vid kreditgivningsbeslut för små och medelstora företag
Syfte: Syftet är att utifrån bankernas definition av små och medelstora företag, beskriva bankernas behov av redovisningsinformation för deras kreditgivningsbeslut och utifrån denna beskrivning försöka dra slutsatsen om en anpassad redovisning är efterfrågad för SME. Metod: Uppsatsen bygger på en kvalitativ och induktiv metod. Insamling av empiri har genomförts genom fem intervjuer med bankanställda. Slutsatser: Banker anger ingen enhetlig definition av SME. Redovisningsinformation är högst relevant för kreditgivningsbeslutet, framförallt när det gäller återbetalningsförmåga, kontroll av finansiell stabilitet och en inledande bedömning av företagets finansiella motståndskraft.
Kränkande beteende på arbetsplatsen : Hur definierar vi kränkande beteende och vad är avgörande för vår definition
Earlier research has shown the difficulty of defining insulting behaviour in the workplace. It has been noted that the individual and subjective definition is connected to the specific situation in which the potentially insulting incidence occurred. In this study we designed a quantitative questionnaire in order to hopefully elucidate the comprehension of insulting behaviour and furthermore enable a more in-depth investigation on how important the contextual meaning is. This study examined 140 (n=140) working adult?s attitudes towards insulting behaviour in the workplace and the importance of the contextual variables.
Activity-based management : En begreppsprecisering
Background: In the eighties the debate concerning the declining relevance of the traditional calculation started. The reason was that the method of calculating not had been changed despite that the costs and manufacturing had changed in many companies. This led to the development of activity-based costing. Management by means of activity information is called activity-based management, but there is no general accepted definition of what the term com- prises. Neither are there any studies which describe within which areas activity information is used as a base for decisions.
Riskuppfattning och krisberedskap bland personal på gymnasieskolor
The study examines risk perception and crisis preparedness among personnel at high-schools. The focus is set on teachers and leaders at four high-schools in Örebro municipality, Sweden. The purpose of the study is to examine crisis preparedness and identify factors which influences risk perception and crisis preparedness. The survey consisted of a questionnaire which was completed by 95 respondents. The results show that better information about the crisis preparedness in the schools is needed.
Prestationsstyrsystem : En undersökning om dess önskade och oönskade effekter
Abstract Title: High-Risk Funds vs. Mutual- Index FundsA study of macro -variables influence on different funds choice Level: Final assignment for Bachelor Degree in Business Administration Author: Moses Yokie & Bo Lemar Supervisor: Ogi Chun & Cheick Wagué Date: 2011-05-25 Aim: The purpose with this thesis is to compare two different types of mutual-index fond and a high-risk fund in relation to the macro variables. The purpose also includes an investigation about if an investor will receives a higher return on high-risk fund than on mutual-index fund in a 10 years period.Method: A quantitative method has been use in this study, where the information has been received from Morningstar. Microsoft Excel has been used to process the collected data in order to calculate the expected return and the risk measures. The result is presented in graphs and tables on the empirical capital, in order to analyse and compare it with the theories and the selected macro- variables to see if there will be any correlation. Conclusion: This research shows that there is no possibility that the macro-variable factors can benefit an investment on high-risk fund or on mutual-index fund in the short run.
