When planning new wind farms, the cost for the internal electrical grid is estimated to account for 8-9 % of the total investment cost. On top of that, the cost for accumulated reduced income over several years (due to electrical losses), has to be added. The economic lifespan is relatively long (about 20 years) which means that an error in the loss calculation could lead to a bad decision basis. The accumulated reduced incomes due to electrical losses can be higher than the initial investment cost for the internal electrical grid.Today, Statkraft Sweden is using a template number when estimating the electrical losses in a wind farm. The actual losses are probably lower than the template number which could lead to an unnecessary high loss cost when planning a new wind farm.The aim of this M.Sc.

In today?s computerized society more and more companies choose to utilize new applications that can ease the way of handling the information. For many of us is imperative that the process as efficient as possible if one takes in consideration the size of savings that this new application can bring.The developer of the evaluated system is SYSteam AB Huskvarna and they are the ones that gave us this assignment. The application that we evaluate is SCM (Secure Connection Manager). It is already used today by big companies such as Telia and Ericsson to search for errors in telephone servers placed all over the country.

[ An abstract in English will follow]Denna uppsats handlar om på vilket sätt användarinvolvering påverkar acceptansen av ett affärssystem. I studien redogörs varför acceptansen påverkas av användarinvolveringen, samt hur påverkan sker och vad som leder till den.IT genomsyrar idag så gott som alla former av företagsamhet. Affärssystem stödjer affärsprocesser i flera branscher, från tillverkande företag till renodlade tjänsteföretag. Ett företag behöver exempelvis anpassa både sina affärsprocesser och det nya affärssystem för allt som sker inom företaget. På grund av komplexiteten som detta för med sig är implementeringen ofta ett stort steg för företaget och dess anställda.

This bachelor thesis? purpose is to investigate how purchase librarians work with foreign language collection management. Since about 15% of the citizens of Sweden are born abroad or have a foreign background, the subject of investigation becomes relevant because it touches a wide user group of the public library.Interviews were conducted with four librarians responsible for purchasing of foreign literature. The purpose of these interviews was to investigate which underlying strategies and thoughts are used as a basis for purchasing.Since the library act does not include guidelines regarding the content of the foreign literature collection, how is the literature chosen and to what purpose?As a theoretical framework a self-developed model was used to categorize the foreign literature into its different functions.

Wallyfy is planned to be a social webmagazine with a focus on good content, with a quality check and moderation of the published content. The author of the study provides Wallyfy with thoughts and ideas about the website content and functionality. The main problem of the study was to explore what makes good content in social media for the potential users of Wallyfy, also using this insight to provide Wallyfy with directions for making decisions regarding both functionality and content. The theory of the study is being used as a starting point for understanding the phenomenom social media and to easier grasp the problem. The method of the study is based on user- centered thinking in design, where the author seeks to understand the participant?s emotions, values and dreams.

The aim of this thesis is to study a number of standards and theories, from the two research areas human-computer interaction and psychology, about how a graphical user interface (GUI) should be composed in order to facilitate interaction between humans and computers. Special emphasis is put on how the GUI should take into consideration the strengths and limitations of human cognition and perception. A study of three web catalogues shows how these theories appear when concretised. The following questions are answered in this thesis:What guidelines and styleguides can be found that specify the design of a user-friendly GUI?How do a few library catalogues on the web match a selection of these design principles?The guidelines are extracted from literature concerning human-computer interaction, psychology, automated library systems and web design.

In the last few years there has been an ongoing debate concerning the methods of assessing the quality of public libraries and their services. This study investigates the opinions and needs of the users at four different public libraries in Malm : the local libraries in Bellevueg rden, Limhamn, and Kirseberg, and the main library in central Malm . The purpose was to find out whether different user groups display different patterns in their library use and, in addition, to identify what library services they prefer. The data were collected through interviews with users and librarians, and by means of a user survey ccarried out at the four libraries. The results indicate that certain differences in the usage patterns do exist between the main library and the local libraries.

?Longboards? är ett examensarbete utfört av Leo Ekbom och Sammy-Sebastian Tawakkoli för innovations- och designingejörsprogrammet vid fakulteten för teknik och naturvetenskap på Karlstads Universitet. Uppdragsgivaren är Space Production AB, projektägare är Dan Edanius, art director och projektledare på företaget. Ett av företagets projekt var våren 2008 att producera Slalom Skateboarding VM och med anknytning till detta växte ett examensarbete fram. Space Production AB började som ett montersnickeri men har idag utvecklats till ett företag som driver fullständiga utställnings- och eventprojekt. Företaget tillhandahåller allt från idéskiss till montering och servning även då huvudsysslan ligger i att producera, installera och lagra utformning från annan part. Uppgiften var att ta fram en produktserie innehållande tre modeller av longbaords med bred spridning.

This master thesis concerns the subject of a reference service named Book-a-librarian. The service makes it possible for the library-user to indulge in a subject with the help of a librarian after having made an appointment in advance. The main purpose of this thesis is to study the function of it. The methods used are a mix of literature and empirical studies to be able to comprehend and explain the practical nature of the service as well as placing the service in a theoretical framework. The empirical study is performed by a questionnaire, where librarians working with the service are asked to participate.

I den här rapporten utvärderas ett antal olika collaborative filtering algoritmer för att ta reda på vilken av dess som lämpar sig bäst för att implementera åt PlanEatSmile i en PHP/MySQL-miljö. Målet är att hitta en algoritm som klarar av att skapa rekommendationer i realtid och med hög precision. Därtill är det viktigt att algoritmen ska kunna skapa rekommendationer åt nya användare (cold-start-problemet) samt att algoritmen ska skala väl när sajten växer.De algoritmer som undersöks är user-based collaborative filtering, item-based collaborative filtering och tendencies collaborative filtering. Samtliga algoritmer undersöks i två versioner. En version som utgår ifrån receptbetyget och en version som omvandlar receptbetygen till  ingrediensbetyg.Algoritmerna testas på data insamlat genom en enkät för att avgöra deras precision.

ProblemEn ensamföretagare måste ofta sitta på en mängd olika kunskaper, då det är vederbörande som i slutändan tar alla slutgiltiga beslut. Enligt Tomas Lindberg själv förekommer det en sviktande försäljning av produkten Wind-X Medium. Kan det då finnas kunskapsluckor hos Tomas Lindberg själv som har ett indirekt samband till dåliga försäljningssiffror? Vilken betydelse kan det ha för företagande och tillväxt om det finns skillnader mellan att vara en företagare eller entreprenör och uppfinnare eller innovatör? SyfteSyftet med studien är att undersöka problematiken en ensamföretagare kan ha med att skapa större intresse och acceptans kring sina produkter. VisionMed en vision att kunna komma med ett eller flera förslag på hur han kan gå vidare med sitt företag. MetodFörfattarna har i denna studie använt sig av en kvalitativ metod, genom att intervjua ägaren till företaget. Författarna har genom att göra olika analyser fått fram information till studiens empiri.
