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.

This report describes a master thesis performed at SICS (Swedish Institute of Computer Science) and KTH (The Royal Institute of Technology) in Stockholm.Ajax stands for "Asynchronous JavaScript and XML" and it's not a programming language, but a suite of technologies used to develop web applications with more interactivity than the traditional web pages.Ajax applications can be adapted for mobile and constrained devices. This has been called Mobile Ajax. While the technique is the same, Mobile Ajax generally is considered to be a special case of Ajax, because it deals with problems specific to the mobile market.The purpose of this thesis has been to examine which possibilities and disadvantages has the Mobile Ajax from developers and users perspective. In addition we compare Mobile Ajax with Java Micro Edition (Java ME) and Flash Lite.This has been done through literature studies and development of a databased chat client (MAIM -Mobile Ajax Instant Messenger). The application sends and receives direct messages in real time between differently mobile devices.

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.

The thesis has been carried out in cooperation with Master Flow AB, Västervik owned by the EWEBE Group. The company produces and sells hot runner systems that are tailor made for the customers.The problem that MasterFlow AB has encountered is in the construction of complex hot runner systems in SolidWorks. With several different lengths, fronts and endcaps that builds the nozzles of the hot runner systems, is affecting the problems for MasterFlow AB. The purpose of this work is to automate the design of hot runner systems so it does not overload the CAD-system SolidWorks.To gain an understanding of the problem, there have been several studies and observations at the company, where the focus has been on how the work is done with the design of hot runner systems. By using help from the corporate management, enough information has been collected to find a solution to these problems.The implementation of design automation has been based on a flowchart that was created.

I started this project with the understandning that European hisory has become more important in government documents as a part in a larger European discourse, and that this fact is likely to be reflected in the chools textbooks. Therefore this essay deals with the task of comparing history textbooks over time trying to find changes. Firstly to find out how much space European history is afforded in the textbooks, and secondly how Europe is described and used in the textbooks. In my first task I will use a content analysis and in my second a conceptual analysis. My material consists of eight books and I have three pieces of older educational materials from the years 1949, 1954 and 1962.

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 2011, I and fellow student at Gotland University created a multimedia game. To fit the time constraints a ?vertical slice? was created. This means a small sample of the game is taken which allows the user to understand how the game works, and at the same time, get a visual demonstration of how the game is designed. The goal of the project was to create a narrative for stadium games in which the backstory is told as players interact with their surroundings.

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.

Purpose: The purpose of this thesis is to clarify and evaluate the concept of scenario planning.Methodology: Our research methodology has a qualitative approach and uses deductive reasoning. The theoretical field of strategy formulation has been reviewed and in specific the concept scenario planning was unravelled and mapped. Thereafter, our model was tested in a case study where the empirical data was collected through personal interviews. Theoretical field: Literature and articles from the strategic management field have been reviewed with a focus on strategy formulation, scenario planning and Williamson?s theory for the creation of a portfolio for strategic options.Empirical base: Personal interviews and secondary sources such as financial reports, articles mainly from industry media and articles found in the databases ELIN and Affärsdata.Analysis: The analysis work constitutes the testing of our model for scenario planning, integrated into Williamson?s portfolio of strategic options for the future.Result: The work has resulted in a clarified model of scenario planning with links to strategic management schools.

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.

The law of 2006 about Equal treatment, has been put in place to stop discrimination of students, example based on their gender. The law has an important function to increase the equality of opportunity between girls and boys in school. Therefore the teacher has an imported roll for raising the equality of opportunity between girls and boys in school. That?s why it?s imported to work gender awareness.
