A power system will inevitably be subjected to transient overvoltages, most often produced by switching operations and lightning strikes. These transient overvoltages may harm sensitive equipment without sufficient protection, but it is not an easy task to predict what transients may occur or how they affect the system. A fault occurred in a low voltage system at Forsmark 2012 and overvoltages from lightning were concluded as the probable cause. The three aims with this thesis are to develop and test a model of the power system at Forsmark 3, analyse the transient behaviour of the system when subjected to lightning surges and identify critical parameters, and lastly to provide a tool for investigating the protection of the system. The modelling and simulations were performed in the freely available simulation program LT Spice.

In today?s society computers are getting a much more important role. To get a computer to work as intended it has to be programmed. A computer program is written with programming languages. There is an abundance of programming languages available today and there are many differences and similarities between them. The different languages have their advantages and their disadvantages where some of them are intended for fast performance, some to be cheap on memory usage, and some are developed to be easy to program on. In our thesis we have chosen to compare four of todays most common languages, C, C++, Java and Python.

Husqvarna is a world leading producer of chainsaws with a well-established brand name. Husqvarna now has an interest in investigating the possibiltiy to expand their production of chains and guide bars to include cutting equipment for timber-harvesters.This project is a technical study which aims to answer questions about cutting equipment for timber-harvesters that have been decided in cooperation with Husqvarna. The questions have mainly been focused on forces, cutting speeds, service and maintenance -as well as general questions regarding the size of the Swedish market.Two methods have been applied to answer the questions. Interviews with retailers of harvesters, producers of harvester heads and harvester drivers.The main findings in this project show that there is a relatively small selection of harvester chains on the Swedish market. In contrast to the selection of harvester chains the selection of guide bars is quite large.

The female dog has a unique reproductive endocrinology, with high levels of progesterone throughout the 70-day long luteal phase. In this project, markers of glucose metabolism were studied and compared from the aspects of breed group and time in oestral cycle. The parameters studied were: glucose, insulin, progesterone, fructosamine and the newly introduced analysis of HbA1c. Hba1c was also further evaluated and discussed as a diagnostic tool in canine medicine.No differences in terms of glucose markers were found between a group of purebreed dogs of various breeds compared to a group of dogs with high risk of dioestrus diabetes, namely the Norwegian and Swedish elkhounds.No differences were found between the two sample occasions, anoestrus and dioestrus, concluding that there is no need for relating test results to the time of the oestrous cycle in middle-aged intact female dogs.There were statistically significant higher values of all glucose markers in diabetic dogs than in non-diabetic dogs. When it came to HbA1c, however, there was a larger overlap between the two groups, compared to fructosamine.

Enköping?s Rugby Club has long lacked a bigger hall to gather their members in, where they can meet and socializes outside trainings and games. Thanks to Enköping?s municipality, The Swedish Inheritance Fund, Swedish Sports Confederation, sponsors and club members the clubhouse will be built out with additional 100 square meters.The project is planned in two phases of which phase one is the buildup of the new clubhouse and phase two is the renovation of the existing part. Phase one started with the first groundbreaking in December 2006 and was finished for the season 2007.

Den här rapporten avhandlar framtagandet av en prototyp för en tjänst där abonnenter hos telekomoperatörer ska kunna beställa och konfigurera sina egna tjänster i betydligt större utsträckning än vad som är möjligt idag.Detta är möjligt och önskvärt tack vare att det pågår kontinuerlig modernisering av den teknik som idag används i telefonnät och telefonsystem.Projektet genomfördes på uppdrag av Tieto i Kalmar som är ett konsultföretag som arbetar mycket med telekomteknik och som har flera stora kunder som arbetar med modernisering av sin teknik.Resultatet har blivit en prototyp där användaren på ett flexibelt sätt kan skapa, redigera och radera sina egna tjänster, samt få en grafisk överblick över sina inställningar.Prototypen är också enkel för uppdragsgivaren att anpassa för demonstration för olika kunder. Den är dessutom anpassad så att det ska gå så enkelt som möjligt att utveckla den vidare med nya komponenter.Från början ingick en student från Rehabiliteringsprogrammet i projektet. Tanken var att kunna genomföra olika typer av användbarhetsanalyser och på så sätt göra prototypen så användarvänlig som möjligt. Då studenten av personliga skäl inte fullföljde projektet redovisas dessa delar av projektet inte i den här rapporten..

This study has been assigned by Bengt Hellman who works at the logistic department at IKEA Torsvik just outside of Jönköping. The task has been to develop a new picking strategy for the Oversize area in the CDC-Warehouse. The reason why IKEA wants a new strategy is because they want to minimize the route length for the forklifts when collecting the orders.By evaluating the current strategies on other areas in the CDC-storehouse, study literature within this subject and look at restrictions for the storing of goods, we have analyzed how the Oversize area works today. We compared the gathered information, to how it should be done according to the literature to be able to work out a new functional strategy.Today, IKEA does not have a working strategy for the oversize area because of lack of time and because all the power has been put on other areas were sales rates are currently higher. This have led to lack of organisation at the Oversize area and items are just put were there is space without first analysing were it should be placed.The strategy that we have worked out and introduced to IKEA builds on easiness of understanding the layout, the employees shall know why an item is placed where it is.

In this work, I have studied whether if one can detect AD / HD in preschool. I have read some literature and searched on the Internet. I have also tried to get to interview people who are familiar with this topic, which has not been easy. I have questioned 13 persons if they would participate in an interview, but most have refused because they do not have time. I succeeded anyhow to get three persons, two special educators and a nurse on the BVC.

By doing this thesis I want to open up farmers and tractor drivers mind to see that there is several risks with their work. There is a number of risks that everybody probably already know about, and hopefully I will, with this work, help them to see a lot more risks, to make them be more careful in the future. I?ve interviewed seventeen farmers in middle and south of Sweden. I?ve also asked them for their opinion and what kind of changes they looking forward to.

This report presents an independent thesis corresponding 15hp and was carried out on Högskolan in Halmstad during the spring of 2014. The thesis is the final course which ends a three-year mechanical engineering program with focus on technical design.The thesis started in an operation which electricians are exposed to every day. The operation in question is cable laying or wiring. The tool they use is called a tension spring and is a long and stiff wire, usually made out of nylon or fiberglass. The tension spring is fed through pipes in the walls and brings the desired cables with it on the way back.

The aim of this Master's thesis is to examine how blogs are used by public libraries for marketing purposes, and how librarians who blog perceive their blog as a marketing tool. The thesis is based on a qualitative study conducted using asynchronous e-mail interviews with librarians representing eleven different library blogs. The theoretical framework and concepts are taken from marketing theory, including Kotler's marketing mix, relationship marketing, and theories on the marketing of non-profit organisations, knowledge organizations, the Internet, and blogs. Our results and analysis reveal that libraries use blogs because they are an easy tool to use, they represent a new way to inform users about the library, they are a way to improve contact with the users and a way to reach potential users. According to the librarians we interviewed, blogs can be used to market libraries in a number of different ways: by disseminating information on the library and its various media and events, by providing a forum to demonstrate the skills of the librarians, and as a way of changing the image of the library.

Title: ?The letters jump?- to struggle with decoding and still understand what you are reading.Author: Maria EkUniversity of UmeåDepartment of EducationSupervisor: Asbjörg WestumExaminer: Fredrik KarlssonKeywords: Poor readers, Structured text talks, Reading strategies, Reading comprehension, Commitment and Motivation.During the past decades, Swedish studies show that reading comprehension and skills in reading strategies have decreased. In secondary school for individuals with learning disabilities there has been a focus on care-taking rather than on comprehension in general, and on reading comprehension in particular.The purpose of this study was to investigate whether Reciprocal Teaching would increase reading comprehension and motivation among upper secondary school for individuals with learning disabilities. The study presents how three 17-year-old pupils and their teacher, discussed expository fact texts during twelve lessons using the reciprocal method combined with power point-presentations to get the students to read more actively with interferences and reflections. The ambition was to make the structured text talks as interesting as possible with texts easy to read, technical aids, structure to make the students feel security when reading and to get committed pupils with an increased interest in reading.The results show an increase in motivation in reading, and the students were more prone to take an active part in discussions..

The importance of good information security and safety grows larger and larger for each day in the information society of today. This concerns citizens, companies and public authorities. At the Swedish Transport Administration, the operation of an information security and safety process has evolved over the years to guarantee that the public authority can be trusted by its citizens, cooperating companies and other public authorities. This responsibility has been assigned to the Information Security and Safety Department (Informationssa?kerhetsavdelningen, ITsa?).In this thesis the aim is to review to what extent ITsa? achieves any business benefits for the Swedish Transport Administration, and to analyze, streamline and come up with solutions to improve their workflow.

The new information society has revolutionised almost the entire world. But the new technique does not only bring good. That which was before only available on paper may today only be available on a computer system. This makes it possible to send data electronically. In the wrong hands that information can become a threat against the security of an individual, a company or even a nation.

On the first of October 2012 the media reported that the women in the Ikea cataloguehad been airbrushed in the Saudi edition. Initially the blame was put on either theSaudi government the Islamic culture or the Saudi franchise. In the end it wasrevealed that the Swedish company Inter Ikea Systems had the full responsibility forIkeas actions and therefore was the culprit behind the airbrushing. On whoseinitiative or why the airbrushing was done the media never found out. These areanswers only Ikea has, although they remain unresponsive to these questionsthroughout the news portrayal.This study methodology uses a qualitative content analysis as framework to furtherinvestigate the news media with support of theoretical perspectives such as mediatheory, power relations and cultural differences.
