This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.

Rapporten tar upp och behandlar ämnet betalväxlar utifrån en utvecklares perspektiv. Två företag som varit i eller nära inpå processen att utveckla en webbshop har intervjuats och jämförts med utbudet hos ett antal olika betalväxlar. Intervjuerna har visat ett resultat som är mycket troligt att man som ny utvecklare kommer i kontakt med i början. Positionen kan då vara både som utvecklare eller som ägare till webbshoppen. Det gick även att konstatera att det fanns ett antal betalväxlar lämpade för olika kunskapsnivåer.

Detta examensarbete har haft som uppgift att undersöka möjligheterna för hur man skulle kunna förbättra gränssnittet för användarna av WIS, Webbaserat informationssystem (1), genom att göra webbapplikationerna mindre dataintensiva. Examensarbetet görs i samarbete med Know IT Candeo AB i Luleå som är utvecklare och förvaltare av systemet. Examensarbetet tar upp några exempel på hur många webbapplikationer fungerar och är uppbyggda idag och försöka se det från ett perspektiv på hur man skulle kunna förbättra gränssnittet för användarna med hjälp av asynkron webbkommunikation. De bakomliggande principerna för asynkron webbkommunikation kommer att behandlas för att sedan kunna beskrivas mer specifikt i AJAX(Asynchronous JavaScript and Xml) tekniken och Microsofts implementation av AJAX som heter ASP.NET AJAX (3). För att kunna utvärdera om asynkron webbkommunikation är användbart i just detta specifika projekt ska några enkla prototyper tas fram..

Storing kinetic energy in a flywheel allows for more efficient driving of electricvehicles. Research in this area is in progress at Uppsala University, where a flywheelwith magnetic bearings encased in a vacuum chamber is being constructed. To makethis possible methods for measuring the current through the electromagnets in thebearings and temperatures in the flywheel need to be developed. This has been thepurpose of this report. The current measurement resulted in a resistive method, andthe implementation of eight measurement circuits in the system.

During the last decades the Swedish local party systems have gone through some considerable changes. The number of parties present in local party systems have increased and in some cases even doubled. This makes coalition building between parties complex and parties will be forced to rethink their coalition strategies and adjust to the new circumstances. Theoretically, coalition building has often been considered and applied to national data and there have been just a few attempts to develop and theoretically explain coalitions on a local level. Thus the aim of this paper is to use different theoretical approaches to local data to test the significance of traditional coalition theories.

In this thesis I analyse and discuss what impact the 2003 U.S lead intervention in Iraq, had for the cooperation against global terrorism between the European Union and the United States. Six years have passed since the Bush administration decided to go on with the intervention, even though they did not have the necessary UN mandate. Due to unsuccessful argumentation in favour of the intervention by the Bush administration, the world got divided. George W. Bush reference to a ?war on terror?, which passed almost unnoticed by Americans, rang alarm bells in many European countries.

?This is a study of two school extern homework activities dedicated to helping students with their homework. The questions at issue are 1) how are the homework activities organized when it comes to financing, planning, marketing and implementation? 2) Who participates as staff as well as students and what are the requirements for participants? 3) What are the reasons for students to attend school external homework sessions? Material was gathered by a survey among the students at the activities and by interviews with principals for each activity. Two main findings are that the homework activities are almost exclusively visited by students with immigrant background and that the main reasons for participating are difficulties with the Swedish language, and parents not being able to help their children with homework.

The purpose of this study has been to examine how the image of the gambler is described by studying a report published by Folkhälsoinstituet [FHI] and a number of chosen articles from the Swedish Evening Press. Discourse theory has been used both as theory, together with social constructionism, and as a research method. The main conclusions of the study are that three different discourses can be identified: the normal gambler, the professional gambler and the problem gambler. The image of the problem gambler is described as a deviant and problematic minority characterized by loss of control, irrational thoughts and dissociative behaviour. The construction of the problem gambler fills three possible purposes for the state: As a solvable problem to handle criticism against negative consequences of gambling, as an argument to avoid competition on the market and as an individual characterized by loss of control in order to legitimize and make the construction of the normal gambler possible..

Value-at-Risk (VaR) is among financial institutions a commonly used tool for measuring market risk. Several methods to calculate VaR exists and different implementations often results in different VaR forecasts. An interesting implementation is historical simulation, and the purpose of this thesis is to examine whether historical simulation with dynamic volatility updating is useful as a model to calculate VaR and how this differs in regard to type of asset or instrument. To carry out the investigation six different models are implemented, which then are tested for statistical accuracy through Christoffersens test. We find that incorporation of volatility updating into the historical simulation method in many cases improves the model.

In Sweden we are spared from large natural disasters. However, in January 2005 part of Sweden was struck by a hurricane. It did not only leave a decimated landscape in its wake. It also left its mark on many people who lived in the south of Sweden. In this paper the reader will be presented six qualitative interviews that build on forestowners' experiences during and in the aftermath of the Storm of January 2005.

The use of insecure networks -such as the Internet- to send and receive information has made the need for preventing unauthorised people reading it yet more important. One of the easiest way to do this is through public key cryptography. However, the problem with this solution is how to tie a specific public key to a certain subject. This is solved by letting a trusted third party issue a certificate that holds, as a minimum, the name of the subject and the subject's public key along with the issuer's digital signature on the information. The rules we make for issuing, revoking and verifying of certificates and the entities that are being used to do so are called PKI - Public Key Infrastructure.

The Swedish exit tax legislation in Chapter 22. § 5 p. 4 IL states that businesses who change its tax residence to another Member State within the EES are taxed as having its assets sold at the time of the change of domicile. This legislation was declared incompatible with the freedom of establishment in case RÅ 2009 ref. 30 due to the fact that businesses who changed tax residence were treated worse than businesses that remained within the Member State of origin.

In order to suggest improvements for the logistics of STARKA, we felt that we had to analyze all the activities which were related to STARKA's logistic processes. Our primary analysis consisted of a rough but comprehensive description of different functions in the company, and the relationship between them. This was performed by following a typical order through the company to see which functions were affected by the order.Since we needed a more thorough view of the company, we decided to analyze the different products STARKA currently has on the market, focusing on economic data such as turn-over, profit, profit margin, deficiency cost and cost of warehousing. We also analyzed the company's choice of manufacturing processes, organization, warehousing processes, strengths and weaknesses.These analyses gave us a clear understanding of the company and its processes. STARKA is a small, function oriented company with a wide range of products.

Teaching preschool children about the environment. A comparative study of how two preschools work with environmental issues.My investigations are based on qualitative interviews and observations carried out at two preschools, one of which has a nature and environment profile while the other works in traditional ways with these questions. I sought to explore the ways in which pedagogues in each preschool raise environmental awareness and, more generally, awaken an interest in nature in the children. The consequences of methodological similarities and differences will be considered.This term paper concludes that the difference between an environmental profile preschool and a traditional preschool working on environmental awareness is not large. The knowledge gained by children in the latter preschool surpassed that gained in the former.

Denna rapport handlar om utveckling av administratörsfunktioner för applikationen QuickPick som är ett värdesystem för ett lager. I dagsläget finns det inga funktioner för användaren att sortera, gruppera eller filtrera vyinställningar i applikationen. De som använder systemet får kontakta Qsys Sverige AB, där detta uppdrag är utfört, för att ändra vyinställningar manuellt. Rapporten behandlar teori om hur ett lager är uppbyggt, hur man programmerar på ett generellt sätt så att det blir enklare att fortsätta utveckla funktionen. Teorin behandlar också hur man på ett användarvänligt sätt skapar ett system för en administratör.Funktionerna kommer att finnas i en webbportal tillgänglig för administratören och är utvecklat i C# och ASP.NET.
