Leisure boats of today have a lot of electronics that needs battery power to work. In additionto that electric propulsion systems have gotten more popular lately, which further increasesthe demand for high battery capacity. The batteries used are mostly lead-acid batteries and toget the most out of the batteries it is important to treat them right. To optimize the electricsystem it is important to have knowledge of how the batteries and the electric motor are usedand which factors affect e.g. efficiency and recharging.A new electric drive that can replace old diesel engines is being developed and needs testingand evaluation.

Information technology (IT) have for several decades been used in university education. An increasing number of classrooms today are built around a concept which uses IT in collaboration with the room itself. However, little is known about the experience of university teachers when working in such classrooms. This study examines the views and opinions of teachers at a Swedish university regarding using and interacting with these classrooms. Furthermore, we identify possible underlying factors that influence these views.

Användningen av Internet och antalet nya tjänster ökar mer och mer. Internet är ett öppet system och för att Internet i högre utsträckning skall kunna användas även vid hantering av känslig information krävs bättre säkerhet. Syftet med denna rapport är att utifrån Karlskrona kommuns säkerhetspolicy samt medborgarnas åsikter om säkerhet, undersöka vilken eller vilka säkerhetslösningar som lämpar sig bäst vid den planerade 24-timmarsmyndigheten. I denna rapport undersöks vilken eller vilka av de alternativa medborgarcertifikat som myndigheter får använda sig av. Målet är att komma fram till en möjlig lösning för elektronisk identifiering inom den framtida, 24-timmarsmyndigheten inom Karlskrona kommun. För att genomföra denna utredning har vi använt oss av intervjuer, enkäter och litteraturstudier. Rapporten innehåller även bakgrundsfakta för att få en ökad förståelsen av innehållet.

For an outdoor environment to function optimally as a playarea requires that it is flexible, that is, contains places and elements that give room for the imagination and for own interpetretations, and also that the children in some way can influence and change their surroundings. It is also important to have variety, both in the sense that the playground has a unique character that distinguishes it from other places, and that it allows many different games and activities. There should for example be room for both wild games of running and moving around where many children can participate, and calm corners to withdraw to for rest or quiet play. A good playground should surprise, challenge and encourage children to discover their surroundings. One way to achive this is to use plants and materials from nature, whose irregular forms and structures can become interesting elements to explore. Vegetation also gives sence-experiences of various kinds, materials like twigs and leafs to play with and a place to play house.

Abstract This report is our bachelor thesis. Our work has taken place at a galvanising company in Sölvesborg. The company faced major changes, of which one was a computerisation process. The new system could involve changes in work practice and in specific tasks, affecting the workers. If the coming system was to support work, from the production personnel?s perspective, we felt a legitimate participation in the development and design of the future work practice, was a requirement that was not met. During our ethnographical studies we noted that conflicts arose between production and administrative -personnel.

The thesis analyzes two different approaches towards responsive web design, Mobile-first and Desktop-first. Responsive web design is a concept for websites whose design is customised based on the screen size. The analysis is performed by collecting views on the methods and also analyzing the usage of mobile and desktop internet to create a prototype of a responsive website where both methods are beeing used.The main difference between the methods is the foundation, where one is designed for mobile and the other for desktop. The thesis indicates that Mobilef-irst gives a better result for the mobile, which unlike the computer has poor performance, smaller screen and poor internet connection, therefore an advantage for the device that needs more focus to maintain a fast response. Desktop-first does not take this opportunity, but focus instead on the computer where the performance is better, which leads to a unnoticeable difference in response time.

Many research reports mention the fact that a huge number of all system development projects never reach a successful ending; with other words never fulfil formulated goals. By identifying and forming success factors (and in some aspect risk factors) that the project manager in practice can use, this study may be seen as a step in the direction towards minimising the high number of failed system development projects. The purpose of this research report is to investigate how a system development project, where the development process is based on a specific development or process model (in this case the Waterfall model), can and should be driven. I aim to clarify what is demanded of a project leader for the specific development process and give an account for which eventual leadership qualities that can be well suited for given situation in relation to the need for technical competence. Among other things the project manager should inspire confidence, drive, be a decision maker, engage and own some form of basic knowledge in the field of system development.

The education in Swedish schools today should be for all children. This means that even if a pupil has reading and writing disabilities the education should be in the classroom with the rest of the pupils. The education should include every one.The aim of my study was to investigate the education with pupils that have reading and writing disabilities. I wanted to get a deeper knowledge about working methods that are used for pupils with these problems.In my study I have used qualitative research methods. I have used group interviews and observational studies.

Dagens människa är ytterst beroende av webbtjänster och med tiden har det blivit fler och viktigare tjänster som startat upp på internet. Viktiga tjänster som internetbanker. Oftast är det bara ett användarnamn och ett lösenord som krävs för att bli autentiserad så man skulle kunna tro att användarna håller hårt i sina lösenord och att de väljer starka/unika lösenord. För många verkar det dock, enligt källor, vara ett besvär. Borde man ha associeringar för att lätt komma ihåg sitt lösenord eller är det för riskabelt? Det har visat att många tycker om att använda ord som förknippas med webbsidan.

The aim of this essay was to investigate how teachers in the preschool class work with literacy. How do they justify the methods used to develop children's literacy abilities? I also wanted to know to what extent teachers enable multimodal approaches within written language practices. My study considers the impact teachers' professional identity has on working methods in the preschool class. I hope this essay will help teachers reflect on their learning approach. I gathered information by interviewing three preschool teachers and one compulsory school teacher for the early years working in three different preschool classes in three different schools.

In this thesis, a computer program that in a simple way can calculate the performance of control loops at the refinery Preemraff Lysekil has been created. The computer program has been adapted to the environment at Preemraff Lysekil. Theories for evaluation has been studied in aspect of reliability and of automatic implementation. The evaluation has been carried out from data collected directly from control loops at the refinery and from simulated control loops with implemented errors. Among the studied methods are Harris index and Stattin´s oscillation index.

My objective for this project was to create a short but thrilling 2D-animation intended as promotion for an online comic book. The purpose of the project was to learn more about animation and graphics, to further my artistic skills and to learn how to work in Adobe After Effects. I also wanted to learn more about scheduling, project methods and how to handle stress. During the ten weeks of the project I have created the story, the storyboard, the character design, the backgrounds and the animation. The voice over was recorded with the help of a fellow student who also made the music and the sound effects.

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.

I den här rapporten beskrivs hur elever mellan åtta och tolv år upplever användningen av datorn och Internet i skolan. Genom att studera användningen av Internet med hjälp av intervjuer, deltagande observationer och informella samtal har författaren i den här rapporten valt att utifrån elevernas perspektiv beskriva deras situation. Utifrån den etnografiska studie och de konstruktionistiska teorier författaren gjort utnyttjas sedan erfarenheter från utbildningstiden för att försökta skapa ett koncept om hur ett framtida klassrum skulle kunna komma att se ut. Undersökningar har gjorts om hur information, kunskaper och erfarenheter utbyts i klassrummet och vilken betydelse det har för användningen av Internet. Men även hur elevernas själva utvecklas och skapar sig ett kritiskt tänkande och att lära sig sortera, för dem, relevant information. Jag har även studerat hur lärarens roll förändras och hur det påverkar undervisningskulturen.

I den här rapporten undersöks stereoskopisk 3D. Vi utreder hur ett spel ska anpassas för att tafram en så bra och tydlig stereoskopisk 3D-effekt som möjligt och så att betraktaren upplever etttydligt djup utan att uppleva ett obehag på grund av effekten. Rapporten tittar djupare på vilkatekniska aspekter man behöver ta hänsyn till vid spelutveckling i stereoskopisk 3D. Samt vilkaprestandabegränsningar som man bör ta hänsyn till vid stereoskopisk 3D. Vi beskriver hurprocessen och framtagandet av prototypen Kodo med anaglyfisk stereoskopisk 3D såg ut.Prototypen togs fram för att testa och analysera resultatet av stereoskopisk 3D-effekten..
