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.

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.

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.

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..

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.

Business and organizations use computer network in a greater extension than ever before, especially for business-critical use. That increase the demand of security for all systems, both against internal and external threats. The demand on the authentication method used today increases. Today they normally uses password or some kind of smart card. I will performa literature study that will investigate the possibility to increase the security in authentication of users without the use of extra hardware.

När det offentliga väljer att upphandla välfärden och köpa in tjänsteutförandet från fristående vårdbolag följer ett behov av nya verktyg för att driva välfärden i önskad riktning. Den här uppsatsen söker beskriva hur kommunala tjänstemän bemöter konsekvenserna av trenden att omvandla de byråkratiska välfärdssystemen till marknader för välfärdstjänster och utvecklar nya verktyg för styrning. Utgångspunkten för undersökningen är de förfrågningsunderlag tjänstemännen formulerar och som utgör grunden för upphandlingsprocessen. Fördjupad kunskap om hur upphandlingsprocessen utformas i praktiken samlas genom intervjuer med ansvariga tjänstemän vid Uppsala Kommun samt marknadschefen vid ett av kommunens utförarbolag.Undersökningen visar att tjänstemännen lägger stor vikt vid formuleringen av obligatoriska krav som utförarna måste leva upp till för att maximera de boendes välmående. Dessa krav utformas för att stärka tydlighet, uppföljningsbarhet och standardisering.

This study is about organizing major sporting events. Sporting events? numerous positive outcomes for the hosting region has resulted in a growing number and size of sporting events globally. The aim of this study was therefore to provide further knowledge about how organizations in major sport events practically and strategically operate and how processes related to organization and leadership can contribute to the success of the event. The study focuses the context of a Swedish national multi-sport event hosted and held by three different cities, three different years.

This master thesis is a part of the DySCAS project at ENEA. The purpose of this thesisproject is to add support for streaming media and USB support to the DySCAS demonstratorplatform.To achieve this, some of the widely used middlewares available today were studied. The onethat proved to be of most interest is CORBA. Although CORBA?s solution to streamingmedia couldn?t be used due to their use of object programming, the CORBA solution didprovide some interesting thoughts regarding how the USB devices should be handled, in thiscase their ?resource inspector? and ?trading service?.Ethernet was the chosen network to support streaming media.
