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.

Upon marketing the system in Europe and the USA cost savings generated from reduced work force have been prevailing. Since the cost of labour is much lower in the Asia Pacific region other factors have to be stressed. The parameters of flexibility and quality assurance may however cover any initial investment in a production system. Our purpose is to value flexibility and quality in a manufacturing context, applied to DAS, in order to use it in investment calculations. In order to make an adequate estimation of different companies, due to problems associated with acquiring correct figures, the Key Success Factors needs to be examined so that the gathering of numbers can be conducted with more focus.

An increasing global population and a worldwide growing urbanization has raised the questionabout the future food security in cities all over the world. Peak-oil limits the access to cheap fossilfuels which threatens the global food-supply chain. This has resulted in a larger awareness anddiscussion related to urban agriculture. Growing crops and keeping animals within the city-borderscould be one way of creating a more robust and sustainable food supply for city dwellers. However,to enable an expansion of the urban agriculture many theorists argue that policies and institutionalstructures that supports and promotes city farming have to be developed.

Ett flygsäkerhetsarbete bygger på ett förtroende mellan individen och organisationen. Det finns en brist inom Försvarsmakten rapporteringssystem, där fördelningen av rapporter med avseende på mänskliga misstag, är avvikande från vad som anses som normalt inom flygverksamhet. Varför avviker rapporteringen i FM från normalbilden? Ett perspektiv som kan förklara denna avvikelse är rättvisekulturperspektivet.Syftet är att diskutera huruvida den ojämna fördelningen av avvikelserapporter med avseende på mänskliga misstag i FM flygsäkerhetsarbete kan förklaras ur ett just culture perspektiv med fokus på regler och styrdokument .Resultatet är att FM inte är att anse som en rättvisekultur. Framförallt är detta på grund av den bristfälliga kulturella grunden, disciplinsystemet och skyddandet av rapporteringssystemet..

Sweden has for years been struggling with high youth unemployment. The problem is also a hot topic of discussion among experts and politicians, often leading to different proposals to solve the problem. The government chose in 2006 to do something about youth unemployment by lowering payroll taxes for employees up to 25 years. But many experts and studies show that the effects failed to materialize.This study will try to find out if the government subsidies have given any effect on the youth unenployment either by new jobs created or by movement in the labor force. I will use a regression model with an dependent, "difference in difference" variable where the change in the number of employed young people are compared to the change in the number of employed in the subsequent age group.The results show that subsidies are not given any positive effect on the youth employment rate in relation to the subsequent age group..

This paper includes astudy of the mutual fund market investors during a selected timeperiod. The reader is given a descriptive picture of how people in different age groups have  acted  in  conjunction  with  the  last  major  financial  crisis.  It  has  been  studied whether people in the different age categories have saved,purchased or sold during this time  period  based  on  theories  and  analytic  material  from  one  of  the  largest  fund operators in Sweden. The result enlightens people?s activity and risk appetite in relation to the fund market. The essay results in an explanation of the underlying cause of the behavior        of         the         people         in         the         different         age         categories.The paper assumes that the market is cyclical and that more crises will occur in the future.

Parallel imports often lead to lowered prices and is therefore regarded as good from a consumer's point of view. From a business'point of view this is not always the case. When do parallel imports occur? Is it possible to prevent parallel imports to protect an introduction of a product in another member state? The purpose of this thesis is to present situations where parallel imports occur and to see if it is compatible with competition law to prevent parallel imports. Furthermore I will analyse the future development after the group exemption of vertical restraints enters into force in June 2000.

Why has some cyber-attacks been more successful than others? There has been in the near past examples of cyber-attacks used with different purposes. How do we understand these chosen targets and what result the attack accomplished?Research has discussed similarities between aviation warfare and cyber warfare, and how the first could explain what is happening in cyber warfare now. There is also opposing opinions whether cyber warfare should be seen as a method to alone force a will on your opponent or if cyber warfare should mere be supporting other military means.

In this essay I have tried to present the ideas and thoughts of the Swedish author Rolf Edberg (1912-1997), journalist, ambassador and county governor. By many regarded as an environment philosopher and the introducer of deep ecology into Sweden. The essay emphasizes Edberg as a modern renaissance man of important knowledge with a rhetorical force to present and generalize the problems the planet Earth is meeting. The paper compares him with Henry Thoreau but also finds a close but perhaps unintended relationship with the German philosopher Ernst Haeckel although Edberg himself claimed to be a Darwinist at heart.The essay stresses on four characteristic features in his authorship namely 1) a holistic view of nature and man, rejecting dualism for monism; 2) a cosmic relationship within the whole universe and also between organic and inorganic matter; 3) the planet Earth is in a crisis due to an uneven and unjust distribution of the resources of the Earth, the nuclear weapon threat and the overpopulation; 4) the evolution and not the religion has the answer to our existential questions..
