The majority of all power cuts that affects individuals and communities are caused by earth faults on the power transmission lines at 10kV and 20kV level [1]. If these power cuts could be eliminated, less disturbances and interrupts would lead to large amounts of money savings.Swedish Neutral has developed such a protection system. When an earth fault occurs power is injected into the neutral point of the transformer. The RCC (Residual Current Compensation) protection calculates a compensation current exactly 180 degrees out of phase to the fault current. Doing this, the voltage at the fault location becomes very close to zero, without affecting the power transmission.The protection system can only compensate automatically for the fundamental frequency (50Hz), and manually for the 3rd, 5th, 7th and 9th harmonics.

The topic of this thesis is immigration policy in the European Union with focus on the Schengen cooperation and illegal immigration. Immigration policies and other policy areas such as asylum and refugee policies have become hot topics on the EU agenda in recent years. Partly because of cooperations like Schengen, but also because a need of a common immigration and asylum policy has emerged.The purpose of the thesis is to give a better understanding of the relations that might be found between illegal immigration to the EU and the Schengen cooperation. Schengen plays an important role in dealing with international migration in the EU and will probably continue to do so in the future.The thesis is a comparative case study with Spain and Germany as the two specific cases. Their national immigration policies are examined and put in relation to the Schengen cooperation.

Purpose: To explore the purchasing function, mainly the supplier selection activities, in the fast fashion apparel industry. The purpose is 1) to explore the criteria associated with supplier selection for fashion products, and 2) to analyze the purchasing activities in order to find characteristics and trends which are considered to be strategic for the buying company. Method: The empirics consist of qualitative interviews with employees with responsibility for the companies' purchasing activities, as well as information gathered from articles, annual reports, and company websites. Result: The study indicates that qualitative criterias have increased in importance, and have become an important part of supplier selection for fashion goods. A number of characteristics where identified as important for purchasing fashion goods, which can affect choice of supplier; examples are increased collaboration, increased re-buys and increased use of logistics services.

Problems with the current energy system, which partially relies on non-renewable fuels, are increasingly recognized. Emissions of greenhouse gases from fossil fuels may speed up global warming, which in turn leads to a number of negative consequences. Nuclear energy is risky and relies on consumption of a scarce resource. This leads to a demand of renewable energy that is also economically feasible. One possible renewable source of energy is solar energy.

This essay focuses on how trafficking is defined and dealt with in recent European policies,and particularly how prostitution take part of these discursive developments. Treaties andagreements on trafficking in human beings and for sexual exploitation have been made bythe European Union and United Nations amongst others, which have been signed andratified by the EU countries in Action Plans. In this essay, five national Actions Plans, fromAustria, Great Britain, Poland, Spain and Sweden between 2007 and 2009, have beencompared in order to see similarities and differences in how the phenomenon of traffickingis done through language. Based on Discourse theory and focus on discursive struggles, theresult show a hegemony around trafficking as a social issue in the Action Plans studied,exploiting humans, mainly children and women, sexually, but also how trafficking is framedas a problem of the nation state and the domestic labour market. It is also illustrated howdifferent meanings of prostitution make the trafficking discourse antagonistic and contested.Finally, the essay discusses the trafficking discourse in relation to EU strivings towardsharmonisation and power imbalances of migration and economy in Europe..

This essay is an evaluation of the act of establishment (2010:197). The act is about different operators' responsibility and accountability for new arrivals to get a more effective integration into society and to speed up the new arrivals' establishment on the labor market. The purpose of this act is to get more new arrivals involved in the Swedish labor market directly. By doing so, it gives these people a possibility to become self-sufficient. This study has focus in four different operators; Employment service, Immigration service and two local politicians from Social democrats (Socialdemokraterna) and Conservatives (Moderaterna).

The combustion engines in today?s vehicles are getting more and more advanced and there are increasing demands on that the engines should operate during optimal conditions. Examples of internal combustion engine parameters which may be carefully controlled are the rate between fuel and air, that this gas mixture is homogenous enough and that it is ignited at the correct moment. Moreover, the requirements of these parameters vary depending on, among other, engine speed and load. To meet these requirements in all occurring operation conditions, it is required that many subsystems work together.

The purpose of this thesis is to study and determine how working in cross functional teams can generate value in an effort to facilitate innovation. An inductive scientific perspective is chosen as the research approach. A single case is investigated with the theoretical framework based on Resource Based View, Intellectual Capital, Innovation theory and theories concerning Cross Functional Teams. The empirical material has been collected through primary data; surveys, interviews and secondary data; literature, websites and further complementary data. The practice of using Cross Functional Teams will enhance organizational learning, knowledge transfer, increase communication and innovation, which in turn will increase the speed and performance of the new product development process.

De mänskliga rättigheterna brister i sin universalism. Många människor som lever i demokratier nekas grundläggande rättigheter därför att de inte är medborgare i den stat där de bor. Anledningen till detta är att nationalstater, som har ansvar för att de mänskliga rättigheterna efterföljs, traditionellt endast anses ha ansvar för sina medborgare. Uppsatsen utreder och synliggör motsättningen mellan mänskliga rättigheters inkluderande och medborgerliga rättigheters exkluderande natur samt vilka konsekvenser detta får för icke-medborgare.Tre teorier om postnationellt medborgarskap presenteras och genom en mer utförlig diskussion av dessa idéer försöker vi i en konstruktiv ansats utforma en mer inkluderande medborgarskapsmodell i två nivåer; den globala och den nationella. I denna modell utgör de mänskliga rättigheterna en juridisk grund för ett medborgarskap för de människor som saknar det nationella.

Följande studie genomfördes för att undersöka koncentrationsförmågan hos 15-årigafotbollsspelare. 15-åriga barn kan uppleva stora skillnader i prestation inom sin idrott ochstudien utfördes för att försöka identifiera ålderseffekter och ifall dessa är orsaken till varförvissa fotbollsspelare är bättre på att koncentrera sig än andra. Relativ ålderseffekt menar attbarn som är födda tidigt på året ofta presterar bättre inom sin idrott än barn i samma ålder somär födda sent på året (Baker, Schorer, & Cobley, 2010).Totalt undersöktes 207 fotbollsspelande 15-åringar, av dessa var n= 78 flickor och n= 129pojkar. Dessa individer fick svara på en enkät, TAIS ? Test of Attentional and InterpersonalStyle (Nideffer, 1976) angående deras koncentrationsförmåga som sedan analyserades medhjälp av ett envägs ANOVA och Chi2test.Föreliggande studie visade inget samband mellan spelarnas koncentration och derasidrottsliga nivå.

Titeln på denna studie är Internalisering av kategoriella par i form utav homosexuella asylsökande. Studiens syfte är att undersöka om och hur föreställningar utifrån ett heteronormativt synsätt, hos handläggaren på Migrationsverket, påverkar asylprövningen av homosexuella. Studien berör hur diskursen i samhället formar föreställningar av den homosexuelle mannen och hur dessa föreställningar blir gällande inom myndighetsutövningen vid Migrationsverket. Studien utgår från teorier av Michel Foucault, samt är kompletterad och avgränsad med hjälp av andra teorier, bland annat Queerteorin. Studien bygger på semistrukturerade intervjuer av sju handläggare vid Migrationsverket, verksamma vid två olika kontor i Stockholm.

The competition has increased with the establishment of the new banks and the credit institutes taking on the market, the big banks are no longer alone on the market.In speed with the increased range, have also the marketing and the recruit of new bank customers become more driven.Bank customers with lacks in the Swedish language, is a segment with potential which doesn?t get used by the banks and in turn of that the bank customers doesn?t get their needs satisfied.The purpose with this survey was to analyze if the four largest banks, Föreningssparbanken, Handelsbanken, Nordea and SEB had prepared strategies that were directed to bank customers with lacks in the Swedish language. In those cases the banks had strategies, respective measures were presented.Furthermore the bank customers with lacks in the Swedish language were studied if they experienced that the banks were using measures to satisfy their language needs in contact with the banks and presented the benefit of them.The information about the banks strategies was assembled through interviews with persons from each bank. The bank customers experience was assembled through a questionnaire survey.The result showed that the banks hade different strategies for reaching out to these customers, it was from showing understanding to multicultural offices. Half of the customers appreciated that the banks pressured themselves for them by being patient, explained the services and in some cases had staff that could several language.

This thesis describes new methods for automatic crack detection in pavements. Cracks in pavements can be used as an early indication for the need of reparation.Automatic crack detection is preferable compared to manual inventory; the repeatability can be better, the inventory can be done at a higher speed and can be done without interruption of the traffic.The automatic and semi-automatic crack detection systems that exist today use Image Analysis methods. There are today powerful methods available in the area of Computer Vision. These methods work in higher dimensions with greater complexity and generate measures of local signal properties, while Image Analyses methods for crack detection use morphological operations on binary images.Methods for digitalizing video data on VHS-cassettes and stitching images from nearby frames have been developed.Four methods for crack detection have been evaluated, and two of them have been used to form a crack detection and classification program implemented in the calculation program Matlab.One image set was used during the implementation and another image set was used for validation. The crack detection system did perform correct detection on 99.2 percent when analysing the images which were used during implementation.

To get rid of our dependence on fossil fuels we need to make use of renewable energy sources like wind power to a greater extent. Even though wind power is a renewable energy source it can still cause some problems for the close environment. One of the problems is shadow flickering. When the sun is low and the wind blows in a direction so that the rotor blades are positioned at right angles to the sunbeams and ?cut? the sunbeams off.

Denna uppsats är en kritisk diskursanalys vars syfte är att studera hur begreppet ?barnets bästa? används och tolkas i asylprocessen för ensamkommande barn. Jag har undersökt hur de tjänstemän som fattar beslut om asyl i fall med ensamkommande barn formulerar föreställningar om ?barnets bästa? och hur begreppet förhåller sig till andra begrepp i den diskursiva praktiken. Detta har jag gjort genom att dels analysera de styrdokument som ska ligga till grund för besluten och dels beslut ifrån migrationsverket och domar ifrån  migrationsdomstolarna.
