Denna tekniska rapport behandlar ett examensarbete utfört på Siemens Industrial Turbomachinery i Finspång. Examensarbetets syfte var att utföra kortslutningsberäkningar samt att ta fram en selektivplan för det avbrottsfria kraftsystemet till en av Siemens gasturbiner. Gasturbinen står ofta långt ifrån kontrollrummet där den styrs ifrån och i rapporten har denna längd antagits till 400 m. Beräkningarna har inte skett på hela kraftsystemet utan en avgränsning till åtta olika delar har gjorts.Rapporten tar upp teorin för gasturbiner, kortslutningar, skyddsapparater och selektivitet. Även vilka olika typer av kortslutningar som finns och deras effekter behandlas.

Oilseed rape is an important crop in Sweden and is grown on about 90000 ha today. The interest in oil seed pro-duction is increasing because of growing demand and high prices for oil seed both in Sweden and Europe. However, an increased intensity in the oil seed production can bring higher risk of yield losses due to fungal diseases. The purpose of this study was to investigate what different fungi are associated with oilseed rape under field conditions and if their incidence is correlated to crop establishment problems. This study was carried out in three parts: 1) investigations on fungal community structure in roots and rhizosphere soils from young spring- and winter rape plants sampled in failed respectively good establishment patches in four fields, 2) investigations on the pathogenicity of fungi isolated from oilseed rape in controlled environment and 3) investigations on the effect of different fungicide seed treatments on germination and early plant development in a field soil naturally infested with damping off- and Verticillium wilt pathogens. The studies on community structure using a combined approach of standard fungal isolation techniques and DNA based methods revealed a high fungal diversity in three out of four studied fields of spring rape and winter rape. For some unknown reason, very few fungal species were identified from the fourth field.

The purpose of the following study is to examine whether or not differences can be found between a group of aspiring police students (N=59) and a student group (N=20). Comparisons were made between the following variables: general illhealth, subjective experienced stress, trait anxiety and the three coping strategies, which are emotion focused coping, problem focused coping and seeking social support. In addition the results were compared with former research on the general illhealth and trait anxiety of the police students with that of a group police officers with several years of experience (N=69).The result of this showed that the police students had a significantly better level of general than the studentgroup. Several positive relations between the variables were found, among others between illhealth and trait anxiety, subjective experienced stress and trait anxiety and also between different types of coping strategies and subjective experienced stress..

Vacuum box leak testing is, because of geometrical problems, not always possible andtherefore an alternate test method with dye penetrant is used. DEKRA Industrial has identifieda need for quality assurance of the method and development of a written procedure withguidelines that lead to more uniform ways of testing.A literature study was done to get a general overview of nondestructive testing (NDT) and tosee how the method is used in different applications. European and American standards werestudied. Analytical and numerical solutions, involving flow simulation, were deemed to berather difficult and beyond the scoop of this project. Thus the problems had to be solved byusing experimental methods.

The purpose of this study is to describe and analyze homelessness in a medium-sized municipality from an organizational perspective. Some of the central questions in this study are: How is the cause of homelessness explained? How do different actors in the community address, prevent and combat homelessness? Who is responsible for the homelessness?This study is based on four semi-structured interviews with organizations that work with homelessness. The analysis is based on problem definition theory.The result of this study shows that homelessness is a problem in this medium-sized municipality even if it is not a big one and that it is often closely combined with substance abuse. The responsibility for the homeless is on the homeless themselves and the social service because that causes is, according to this study, individual based.  .

Den här studien är en undersökning av hur organisationskulturen i en svensk polismyndighet tar sig uttryck i personalens förväntningar på handledning. Metoden som använts är enkel fallstudie. Sjutton intervjuer har genomförts, varav femton individuella och två i grupp. De totalt trettio deltagarna är indelade i fem grupper; ledning, yttre befäl, ordningspoliser, projektledare och handledare.Resultaten visar på tre kulturella fenomen som kommer till uttryck i gruppernas förväntningar på handledning. Dessa består i vertikala och horisontella spänningar i myndigheten samt ett fenomen som vi valt att benämna "den enda chansen".

This study aims to investigate how and why teachers use social media to reach their students, and how they handle different levels of computer literacy among students.The purpose of this study is to investigate the experience of teachers using social media in their teaching. I have done interviews with two teachers, who use social media in different ways. One of the teachers makes her students publish their work on the Internet on wiki-spaces, and the other one use Facebook for discussions and teamwork. This report uses the pedagogy theories laid forth by Vygotskij as a vantage point to analyze the answers from the teachers. I have also looked at some of the published student texts on the Internet.This study concludes there are students who don?t have access to computers and Internet at home.

I nuläget packar Siemens Industrial Turbomachinery till montage av en gasturbin ad hoc vilket leder till att varje projekt är unikt. När montören ska montera gasturbinen används en stor del av arbetstiden till att lokalisera artiklar genom att öppna och leta igenom lådor.Syftet är att ta fram de förutsättningar som måste uppfyllas för att gasturbinen SGT- 800 ska kunna packas i en monteringsvänlig ordning. Målet med en monteringsvänlig ordning är att tidsåtgången för att lokalisera artiklar ska minska.Tre bromsklossar anses vara försenade artiklar, avsaknad av återkoppling mellan Packningen och monteringen och avsaknad av packinstruktioner. I analysen visar det sig att andelen försenade artiklar ligger på en för företaget acceptabel nivå. I analys och diskussion behandlas återkopplingen av information mellan olika avdelningar och möjliga packinstruktioner.Resultatet presenterar riktlinjer till en packningsprocess och hur försenade artiklar ska behandlas.

Thiswill be achieved through a study of Rosengårdsstråket inMalmö based on the question "What is a Stråk?".Malmö has experienced a major change in the last 15years. From being an industrial city with economic problems,Malmö is now part of the dynamic Öresund Region,and a knowledge city with great optimism. New parts ofthe city is about to grow up that reinforces the image ofMalmö's new identity.The next step in Malmö's development is to make thecity even denser and interconnect the inner city and thesuburbs to create a more sustainable city.

Quadrotor UAVs are self-stabilizing, autonomous flying machines that has recently become more popular than ever. Unmanned Aerial Vehicles have their roots in the military, where they were developed for use in reconnaissance and combat. During the last few years, advances in the fields of electronic sensors, electric motors and microcontrollers have enabled smaller designs and autonomic flight control even for private use. The quadrotor, which is the particular kind of UAV we are looking closer at in this paper, has 4 rotors in an X-like formation. This configuration has many advantages such as good lift capacity, non-complex mechanical structure and serviceability.In this project we aquired a current overview of the domain and determine whether it is possible to construct a quadrotor UAV designed for use in a WISENET sensor network on a low budget and short time schedule.Based on existing community project AeroQuad, a quadrotor is constructed with a budget of about 500 euro.

Problemet med illegal fildelning och nerladdning idag är att upphovsmännen bakom varje drabbat verk inte får betalt. Denna rapport syftar till att ge en inblick över processen av vårt kandidatarbete, en webbtjänst och en lösning på problemet. För att skapa webbtjänsten genomfördes först en grundlig research. Vi kartlade konkurrenter, undersökte olika sätt att finansiera produkten och hur upphovsmännen skulle få betalt. Resultatet blev en webbtjänst där användaren bland annat kan lägga upp sina alster, ta del av andras och även använda scenen (en idé som utvecklades under arbetets gång) där användaren kan boka tid för liveframträdanden, alternativt använda den som distributionskanal för deras uppladdade verk..

The consumer today is affected by a considerably larger number of world surrounding factors than she used to be, borders between different cultures and other consumer differences are being erased to a growing extent. The consumer can easily get its inspiration from many different directions which become clear in the common life. We eat sushi for lunch, we?re driving German cars and we?re having dinner with international business partners. The community also exposes the consumer for a more intense noise from offers, impact and marketing.
