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 thesis is an investigation of Iranian immigrants and their use of libraries in Sweden. It isbased on a combination of a qualitative and a·quantitative method.Using a qualitative method, I give an outline of the history of lran from ancient times up to the present, as well as the different ethnological groups in Iran and their cultures. The main objective of this part is to clarify the contrasts between Iranian and Swedish cultural, social, linguistic and family structures, and also the characteristics of the crisis that most immigrants go through on their arrival in the new country. The qualitative method also involves structured telephone interviews with eight highly educated Iranians.This method was supplemented by a quantitative study through questionnaires of the attitudes· of lranian immigrants to libraries and reading. Iranians in Sweden turned out to be frequent Iibrary users.

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

This papper i about trying en educational method called writing connected to dialog. This is tried on adult students studying to work in Swedish day care. The purpose was to see if this method could make a difference in classroom democracy..

The payment for produced grain is constantly going down in price. It is important for farmers to become more effective in cultivating more land in a shorter time perspective. At the same time we have to calculate with the risk of getting lowered subsidies from the EU. This is why I would like to find out the possibilities for establishing winter wheat without ploughing. I hope to find a difference in the number of plants due to different soil preparations. With this experiment I expect to find out whether I can establish winter wheat at a lower cost, with the same numbers of plants per square meter.

This thesis describes redesign and adaption of a products housing. In order to make it more economical to produce at a lower production volume. The thesis is based upon a prototype that a previous student developed for injection moulding. The goal is to find alternative manufacturing methods, but also to identify parameters that affect the cost of the injection moulding tool.The housing must be tough in order to protect the circuit board inside. But at the same time it must allow sound, light an electrical communication to pass through.

The aim of this paper is to spread some light over contract treatment from the perspective of the District Courts, Social Services and Probation Services, and understand the reason for local variation of the number of people sentenced to contractual treatment.Essential questions asked in this paper are; What advantages and disadvantages are known by the cooperating parties regarding contract treatment in comparison to prison? What parameters are considered when the cooperating parties decide upon contract treatment? What impact does the shared responsibility of cost have? What do the respondents think is the reason for the local variation?In order to answer the essential questions a qualitative and descriptive method has been used to highlight the main question of our study; What is the reason for the local variation in number of contract treatment sentences in Halmstad and Ystads district courts?The paper shows that the local variation between the Probation Services districts is dependent on the conditions to propose a contract treatment. In Halmstad it is not conditioned for the Probation Services to have a responsibility agreement with the Social Services to the same extent as for the Probation Services in Ystad..

Under senare tid har det på den svenska livsmedelsmarknaden växt olika miljö- och kvalitetsmärkningar som grundar sig på olika kriterier. Vi har i denna uppsats valt att studera två av dessa: Svenskt Sigill coh SVENSKODLAT. Syftet med denna uppsats är därför att ur ett producentperspektiv, undersöka huruvida Svenskt Sigill och SVENSKODLAT certifieringarna kan utgöra en strategisk konkurrensfördel. Vi har identifierat tre aspekter som var och en i varierande grad kan sägas bidra till att de båda certifieringar vi studerat skapar konkurrensfördelar. Dessa tre aspekter vilka vi sammanfattat i en ABC-modell är: adding value, barrier to entry och cost saving.

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

This project has been made in cooperation with Stora Enso Research Centre Falun (Research). Thebackground of the project is that Research has customers who demand a method to measure the quantityof varnish online in offset printing. The aim with the project is to investigate if any test method correlateswith the quantity of varnish and to improve the understanding of the variables in the varnishingunit. The goal with the project is to develop a functional method. Two printing trials have beenperformed.

There is no commonly accepted definition of a business method. It ought to consist of a method or a process of doing business. Business methods constitutes a broad category of patents, it is hard to tell exactly what can be interpreted in to the term. Most of the world's legal systems have made an exception from patentability for business methods. In the USA the exception was abolished in a case 1998.
