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.

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 stability of railway embankment is essential for safe transport. In order to ensure safe transport, water should be allowed to freely drain. Furthermore, as the engine driver has to be able to see signs, and people working on the embankment are supposed to easily see flaws on the rails to ensure safety for the passing trains, plants should not be allowed to grow on the embankment. In Sweden there are 12 000 kilometers of railway tracks and 25?30 % of them are treated for weed control every year.

Volvo Construction Equipment AB Components Division i Eskilstuna är mitt inne i ett omorganisationsarbete där fabriken byggs om från funktionsverkstad till flödesorienterade grupper detta för att effektivt möta den växande orderingången. När gruppernas värdeflöden tydligtgjorts återstår ett intensivt arbete med att optimera ledtider, lagernivåer och produkter i arbete med mera. Ett kraftfullt verktyg för att stötta detta arbete är diskret händelsestyrd (DE) simulering. Det har genomförts flertalet DE simuleringar tidigare på företaget, då främst av konsulter. I den nya fabriken finns en önskan om att utföra detta arbete själv.

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.

The building industry consumes approximately 40 % of the total energy consumption in Sweden, where the using stage is dominating with 80 %. There is a lot of work in progress to reduce energy use in the building industry, and the demands from authorities regarding energy use increases. As a part of this work Building and planning department of Sweden has established a requirement that has been applied since 2006, and restricts a maximum energy use for buildings.The requirement includes that an energy simulation must be done in advance to demonstrate that it is possible to meet the demands.Reality is however more complex than an energy simulation program, that frequently underestimates the energy use of buildings. The purpose of this thesisis to study and analyse deviations between estimated and actual energy use in modern apartment buildings. The study includes four apartment buildings in Stockholm, Gothenburg and Jönköping that were built in 2007-2009.

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 report aims to describe the austenitic stainless steel Sanicro 25 from a thermomechanical point of view. The thermal and mechanical properties of the material make it suitable for use in coal ? and thermal power plants. By the use of Sanicro 25 it would be possible to bring the efficiency of these plants up while bringing the carbon emissions down.A material model is created from material testing and validated through simulation in the finite element software Abaqus. The model that has been derived describes the material behavior during loading and stress relaxation for the first cycle in a thermomechanical fatigue test well.

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.
