Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

This study illustrates how the power relation between the trustee and principals are experienced and maintained in proportion to the missions design. The main focus lies on understanding of how trustee perceives and applies the mission`s cornerstones and how power can be expressed in the relationship between trustees and principals. Nine semi-structured interviews were conducted with trustees whose principals were mentally disabled. The interviews were then analyzed with the support of Foucault's concept of discipline, knowledge, control, surveillance and reward/punishment and Tilly's theory of persistent inequality We have obtained an understanding of the complexity of the assignment regarding the mission`s cornerstones who goes into every other, and all respondents agreed that the cornerstones should be considered as a whole. We concluded that the trustee on the basis of the mission's design possesses a power that is necessary and important to have regarding the relation to his principal and its social network.

The purpose with our essay was to increase our knowledge about what social workers, with experience from working with drug addicts, perceive as the explanations to a person stopping the abuse and succeed in staying drug free. Our framing of the question was:- How do social workers define the term drug free?- How big a roll do the social worker believes she/he has in the process in which a person stops abusing drugs?- How do the social worker work with a person towards getting that person drug free?- What do the social worker believe to be the reason why a person stops abusing drugs?- What do the social worker perceive as helpful for a person to stay drug free?We did qualitative interviews with six social workers. Our main conclusion was that it is difficult to define the term drug free. The reason for stropping the drug abuse can vary, it can be the family situation, "hitting rock bottom", finding love or tiring.

Det här examensarbetet har utförts på uppdrag åt Trollhättan Energi AB (TEAB). Examensarbetet är en utredning beträffande förutsättningar för sammankoppling av TEAB:s och Hjärtum Elförenings elnät.De nuvarande ledningsnäten har radialnät och det innebär att det endast har inmatning från ena ledningsänden. En sammankoppling skulle ge möjlighet till sektionerad drift vilket innebär inmatningsmöjligheter från båda ledningsändar. Det gör att ledningsnätet blir mer säkert, tillförlitligt och effektivt.Ett förslag på ett nytt ledningsnät där delar av TEAB:s och Hjärtum Elförenings ledningsnät är sammankopplade har tagits fram. Med det nya förslaget blir ledningsnätet mer driftsäkert och uppfyller lag- och myndighetskrav.Beräkningarna som ligger till grund för arbetet är teoretiskt utförda.

Detta examensarbete har utförts på Vattenfall Eldistribution AB i Trollhättan och syftar till att beräkna förlustförändringarna i lågspänningsnätet då mikroproduktion i form av solceller ansluts.Genom att ansluta mikroproduktion i lågspänningsnätet kan nätets energiförluster reduceras. Denna reducering samt den energi som inte behöver överföras från överliggande nät anses vara den nätnytta solceller ger upphov till.Samtliga elproducenter som är anslutna till elnätet har rätt till ersättning för nätnytta uppkommen av produktionen. Ersättningen skall baseras på inmatad energi samt vid vilken tidpunkt inmatningen sker. För mikroproducenter är det svårt att motivera att i varje enskilt fall beräkna nätnyttan, varför ett generellt schablonvärde beräknats för Vattenfalls lågspänningsnät. Beräkningen har utförts utifrån uppmätta sol- och lastdata på sex olika lågspänningsnät vilka tillsammans anses representera ett generellt nät.

A large number of children and teenagers are placed in foster care for various reasons. Social services have a responsibility to follow up youths and ensure that they have the same opportunity for positive development as other young people. A qualitative study was conducted with an abductive perspective by gathering material from social workers in this particular field. The research design of this study is an interview study. The theoretical premise was Bronfenbrenners ecosystem theory and Maslows hierarchy of needs theory.

Detta examensarbete har genomförts i samarbete med Sourcecom Svenska AB. Sourcecom Svenska AB arbetar med kommunikationslösningar inom IT-kommunikation, IT-säkerhet och telefoni. Examensarbetet går ut på att undersöka konceptet Bring Your Own Device (BYOD) och föreslå olika lösningar beroende på företagets informationssäkerhetskrav. För att förstå konceptet BYOD behövs först en inblick i hur ett policybaserat system fungerar. Rapporten undersöker och förklarar tre olika Network Access Control (NAC) lösningar som är policybaserade.

Uppsatsens syfte är att pröva tesen att Radiosportens sändningar har blivit mer jämställda mellan 1995 och 2007. Det som undersökts är utrymmet som kvinnor och kvinnligt idrottsutövande får i sändningarna i förhållande till män och manligt idrottsutövande. Metoden att besvara frågan är kvantitativ. Radierade sekunder har räknats och fördelats mellan kategorierna kvinnliga och manliga röster och kvinnligt och manligt idrottsutövande. Kriterierna för jämställdhet är att de kvinnliga rösterna är proportionerligt representerade och att kvinnligt idrottsutövande får ett proportionerligt utrymme i Radiosportens sändningar. Undersökningens resultat visar att Radiosporten har blivit mer jämställd under  undersökningsperioden, men att det inte går att säga att ökningen är stabil från år till år. Resultaten visar också att kvinnor och kvinnligt idrottsutövande inte får utrymme i nivå med andelen kvinnor eller omfattningen av kvinnligt idrottsutövande generellt..

In a globalized world, competitiveness is based on the high IP (intellectual property) of our export products and innovations are therefore important for new companies to establish and develop. It´s not enough to just have big international companies but it is also necessary to invest in new companies that can be competitive in the future. By helping entrepreneurs with innovation support in the early stages, new technology-based businesses are established and developed. The purpose of this paper was to examine how innovation support in the early stages affects the establishment and development of new technology-based companies. Furthermore, we investigated how this will affect Sweden's international competitiveness.

The purpose of this study is to examine the information seeking behaviour among unestablished archaeologists. Special attention has been directed to the areas of informal communication and the development of personal networks. As a former archaeology student I have been able to apply my previously acquired knowledge when writing this thesis. The empirical study is based on nine interviews with archaeologists each with more than one and less than four years of professional experience. They all have various experience of working as a fieldarchaeologist and five have simultaneously worked as university researchers.

This report is a market research for the company 4 Body and Mind, a start-upcompany that works with personal training online. They wanted to know if themarket for elderly care could be interesting for them to enter. This report is hence aresearch of the market for health and welfare technology in elderly care within thepublic sector in Sweden. A general fact is that the world's population is getting older.This combined with rapid growth of individuals in the age 65+ changes the demandson the elderly care in Sweden?s municipalities.

In theory, the logic behind partnerships is simple: All organisations have strengths, but no organisation has all the strength required to do everything. Triggered by global perspectives and challenged by sustainability objectives, the United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro in 1992 pointed out needs for corporate responsibility. In this conference, Private-public partnership, PPP, was identified as a potential way to work towards sustainability, especially as a way to emphasize a corporate responsibility commitment. Nowadays, organizations exist to satisfy the needs and interests of all their stakeholders, such as customers, markets, shareholders, as well as secondary stakeholders such as media, NGOs, and society at large. Addressing all stakeholders and working towards a sustainable business development makes PPP a potential solution, but also a source of challenges.

In this study we are focusing on Instagram and marketing. We want to know how Web 2.0 and social media creates a new place for companies to market themselves and mostly how they are using the social network Instagram. The amount of swedes using Instagram is 28% and that is the double of what it was a year ago. This creates a whole new place for companies to market themselves and most importantly; it?s free.Our question at issue is In what way is fashion and interior design companies using marketing and Web 2.0 on Instagram and how does it reach individuals? To get an answer we contacted eight different companies and asked if they would like to answer some questions.
