This thesis treats the subject of a complete steady state and dynamic model of the VSC-HVDC covering both the AC and DC system-side of the converter. The topology of the model is recreated after the scheduled transmission line in the south of Sweden, called SydVa?stla?nken. The topology covers both a simple two terminal connection as well as a multi-terminal one. This model is to be implemented in the power system simulation program ARISTO.

This report is the final step in the Bachelor of Science program in Building Construction Engineering, Department of Engineering Sciences, Uppsala University.The purpose of this study is to highlight the difficulties and possibilities that could involve the introduction of new energy efficient technologies and changing work around this technology. This study focuses on energy use at a construction site or other temporary workplace where so-called portacabins are in place to address the need for temporary facilities.The method for obtaining knowledge on the subject was mainly interviews with site managers working in Svevia AB's various activities. In conjunction with the interviews I visited construction sites and portacabins if it was possible.My most important suggestion to Svevia AB concerns a better organization in order to make poratacabins more efficient on energy and costs. The company should also evaluate and monitor the energy efficient portacabins that are in operation.Expected energy savings of new technology may not materialize if there are gaps in information, education, technical services and technical maintenance. It is very important to utilize the experiences of new technology.

This thesis is closely related to the Dynamically Self-Configuring Automotive System(DySCAS) project. DySCAS is a middleware for electronics in an automotive system. Thethesis work has been performed in cooperation with ENEA. Parts of the demonstrationplatform Self configurable High Availability and Policy based platform for Embeddedsystem (SHAPE) developed for the DySCAS project by ENEA have been used in theimplementation phase of this master thesis.The goal of this thesis was to evaluate how the Meteor MW, an offspring of the DySCASmiddleware, should handle QoS and to design a Quality of Service Manager (QoSM) for theMeteor MW that fulfilled hard real-time requirements. The thesis also had the objectiveof analysing and identifying the requirements on such a QoSM from a QoS perspective.Specifically the requirements to guarantee real-time support for applications running onthe MW.

Earlier studies have shown that musculoskeletal disorders among animal keepers are more frequent than in other occupations. Most of the farms have expanded and the farmers who used to work alone have suddenly become a work manager with several employers. There are only a few studies made on the work environment in dairy farms. Our study is based on a questionnaire and is a part of a project called large dairy herds. The study is based on data from the persons who milk most of the time. The questions they had to answer were about the work environment, musculoskeletal disorders and the psychosocial environment. The results of the survey are presented in diagrams and figures. It was common that the dairy producer themselves answered the questionnaire.

Att uppleva oro och ångest inför en operation är vanligt och kan manifestera sig såväl psykologiskt som fysiologiskt hos patienten. Flertalet mätinstrument och omvårdnadsåtgärder existerar, med syfte att finna och lindra oro och ångest. Avsikten med denna systematiska litteraturöversikt var att beskriva omvårdnadsåtgärder för att lindra patienters preoperativa oro och ångest. Genom litteratursökning i sex databaser, bland annat PubMed, CINAHL och Psychinfo, framkom fyra kategorier av interventioner: Att få information via video: Att få skriftlig eller muntlig information: Att lyssna på musik och: Att få känna värme eller beröring. Resultatet visade att samtliga omvårdnadsåtgärder mer eller mindre lindrade oro och ångest, där relationen mellan patient och vårdgivare, och individanpassade interventioner var viktiga, exempelvis då musiksmak hade betydelse, eller att viss information inte var nödvändig.

Då matförgiftningarna runt om i världen stadigt ökar, har livsmedelsinspektörernas roll att kontrollera hur livsmedelsföretagen uppfyller livsmedelslagstiftningen blivit allt viktigare. År 2006 ändrades den svenska livsmedelslagstiftningen till att bli mer överensstämmande med EU:s livsmedelslagstiftning. I och med denna förändring ändrades livsmedelsinspektörernas roll till att kontrollera hur väl livsmedelsföretagens rutiner för egenkontroll uppfyller livsmedelslagstiftningen. För att kommunikationen under de kontroller som livsmedelsinspektörerna utför på livsmedelsföretagen ska kunna fungera på ett effektivt och noggrant sätt, krävs det att båda parter hjälps åt. Då forskningen inom det aktuella området idag kan ses som bristfällig, har detta legat till grund för detta examensarbetes inriktning.

Communication of sustainable development has become an increasingly important part of organisation?s corporate branding. Consumers demand more transparency from businesses and want to know more about how they work with these issues. An important part of how internal communication can be used to reach organisational success involves organisation?s employees.

Test is an area in system development. Test can be performed manually or automated. Test activities can be supported by Word documents and Excel sheets for documenting and executing test cases and as well for follow up, but there are also new test tools designed to support and facilitate the testing process and the activities of the test. This study has described manual test and identified strengths and weaknesses of manual testing with a testing tool called Microsoft Test Manager (MTM) and of manual testing using test cases and test log templates developed by the testers at Sogeti. The result that emerged from the problem and strength analysis and the analysis of literature studies and firsthand experiences (in terms of creating, documenting and executing test cases) addresses the issue of the following weaknesses and strengths.

AbstractThe purpose of the present study was to clarify and describe what image men and women present and communicate in their profiles on an online dating site. Further has been investigated if traditional gender roles and stereotypes are as pronounced on this online platform or if it offers a space to go beyond traditional formations. The theoretical framework of this study consisted of a social psychological idea and understanding of identity as well as a gender theoretical perspective. The methodological points of departure were hermeneutic and the data consisted of ten male and ten female member profiles on match.com. The results of the study was divided into three themes, the emphasis on positive qualities, the attractive body and project manager to one?s own life.

This report describes the development process of a pipe clamp used on exhaust system for cars. It is made based on the manufacturers desire to improve and make the clamp easier to manufacture and to reduce its price to their customers. This should be done either by manufacturing the clamp in one piece without an expensive and work intensive welding process, or by generating ideas of how to develop a brand new type of clamp. Investigating the market for similar products was done to eliminate intrusion of other manufacturers? patents but also to generate ideas.

I dagens samhälle kan vi se en allt starkare trend i riktning mot internationalisering och globalisering. Genom att det har blivit lättare att förflytta sig över nationsgränserna har detta öppnat dörrar för såväl privatpersoner som företag. I och med detta har många företag och organisationer fått anpassa sig till, lära sig att förstå och hantera kulturell mångfald. I globala företag är det inte ovanligt att man som manager eller ledare arbetar tillsammans med eller leder anställda med annan nationell kulturell bakgrund än sin egen. Detta kan ibland leda till missförstånd och merjobb, men bidrar även till dynamik och inspiration på arbetsplatsen.Vi genomförde en kvalitativ undersökning som grundade sig på tre djupgående intervjuer med managers på olika nivåer på ett multinationellt callcenter i Wien.

The Oresund Region, consisting of the Swedish county of Scania and the Danish islands of Sealand, Lolland, Falster and Bornholm, is widely recognised as a successful example of European cross-border co-operation. The purpose of this region building project is to form a cross-border fully integrated functional region in order to accomplish a high level of economic growth and employment.This thesis argues, by the means of discourse analysis, that the project can be viewed as a kind of post-politics, defined as a politics that under a neoliberal hegemonic consensus strives to manipulate citizens (and to redefine them as consumers and investors) into better economic performance.This manipulation is carried out by extensive discourse production aimed at convincing people that the Oresund Region exists, that it is a successful region, and that the people who inhabit it are also successful. The deliberate vagueness and contradictory character of the Oresund discourse is investigated and explained as a discursive strategy to incorporate as many views and desires as possible..

Most of the portable electronic devices use a battery as a primary power source. Nowadays, when the applications are becoming smaller and smaller and more power efficient, the designer needs to concentrate more on reducing power consumption, using secondary power sources and introducing power storage devices. Multiple power source availability and a power storage device on the board will make the applications much more useful and efficient in everyday use. This thesis proposes a power supply unit (PSU) for wireless sensor platforms which is capable of supplying a sensor node with energy from multiple sources, as well as status information from the PSU. Present power storage devices, like electric double-layer capacitors (EDLCs) and batteries, have become more and more common as their characteristics have developed.

Studien undersökte hur arbetet inom den personalkooperativa verksamheten upplevdes av medlemmar och anställda, samt skillnaden dem emellan. I denna studie användes personalkooperativ för att det där ingår både medlemmar, som är ägare av kooperativet, och anställda. Syftet uppnåddes genom intervjuer där tre frågeställningar användes: vad upplevda erfarenheten är av att ingå i ett personalkooperativ, hur företagets handlingar stämmer överens med de aktuella kooperativens sju principer, samt hur deltagarna förhåller sig till Maslows behov.  Resultatet visade dels att möjligheten att själv kunna påverka arbetet var skälet till varför deltagarna valt att ingå i ett kooperativ. Dock angavs som negativt saknaden av en chef och den bristande ekonomin. Skillnaden mellan medlemmar och anställda framgick genom att medlemmarna fokuserade mer på verksamheten som helhet medan de anställda lade fokus på interaktionen mellan kollegor.
