The goal of this paper is to provide a model for a sustainable electricity system to an island, in the Pacific Ocean near the equator.The method which has been used is to model supply and demand of electricity in the computer program Stella, through the creation of a dynamic system that balances them against each other. The result from the model will then be used to calculate the electricity price per kWh for the island.The result of the work is that electricity from solar energy is comparable with electricity produced from oil, if the oil pays for all its external costs, and the potential for pumped hydro storage plants is located. It also requires that consumers of electricity can be their own producers to avoid the expenditure of tax and reducing the cost of distribution. But since oil is a finite resource and has had a rising cost in recent years, while solar energy has had a declining cost, perhaps this will be a more competitive solution in the future.

This study examines how professional social workers relate to problematic computer and video gaming as an addiction. It is a qualitative interview study aimed to describe and analyze how professional social workers, who in some way work with problematic computer gaming, relate to the player?s problems in terms of a concept of dependency. The theoretical approach is based on social constructivist theories of discourses, normality, the definition of dependency and diagnoses. The study was conducted through five qualitative half structured definition interviews with professional social workers that work directly or comes in contact with problematic computer gaming.

Creating instructions is not just about words, but also about text structure. A company creates many instructions to document their management systems, which often are presented through an intranet. This study examines how the text can be presented to make content understandable and give employees the knowledge to take action. An interview survey was made at Skanska Sweden and their management system "Vårt sätt att arbeta". The results show that it is mainly about creating an overview of the system and creating separations between different text sections.

Today it?s common that companies and organizations are facing several challenges and problems when it comes to making their IT-environment more efficient. Some of these are the management of user?s computers and file security. Comput-er users are often tied to their personal computer due to personal programs and files.

It has become more popular to work abroad and companies have become more global than they used to. A big reason for this is due to globalization and the progress done within the field of technology. Because of this aloofness that occurs, a gap between the expatriates? personal life and his or her working life develops. The cases focused on in this paper includes people who are distanced from their private lives at least a few consecutive months but are all aiming to get back when they are done with their individual errands.

Abstract During object-oriented system development, programming should be preceded by analysis and design to assure that the system fulfils the demands of the customer and simplify during the development phase and documentation. When modeling the analysis and design phases, several different notations may be used. One of these is the UML (Unified Modeling Language) which this thesis will cover. The aim is to compare the use of the UML i practice versus what is said in the literature. The investigation is built upon interviews at different companies to receive their reflections about the UML.

Chapter 1 defines the aim of the project and gives a general orientation about ground heat extractors. In chapter 2 physical processes that could be expected to be involved in the heat transport around a ground heat exchanger are discussed. It is shown from a literature study what amount of moisture transport due to thermal gradients there could be expected in a ground heat exchanger. The conclusion is drawn that the moisture gradient (Sr) is of same magnitude as the driving temperature gradient (°C). At the expected amount of increased moisture around the pipes the moisture transport could be considered to have a little effect on the brine temperature.

In recent years, existing solutions for cooling personal computer CPUs have been supplemented by a new product category, factory sealed water cooling loops. These systems, consisting of a water block with an integrated pump, a fan and a radiator, perform well compared to the air cooling solutions but are less effective than larger, custom-built water cooling systems.This project aims to explore the most important aspects of a factory sealed system and to identify possible cost-effective enhancements of the performance.The most significant differences between the different groups of water cooling loops are the block design and the pumping power. The performance of both categories is also largely dependent on the fan power, but increasing fan power has a large negative impact on the noise level.Both radiator size and fan model choice appear, in tests, to be relatively unimportant, presuming that the noise level is kept constant. The position and direction of the fan, however, has significant impact on both the temperature and the sound level.Water blocks can be designed in several different ways, both regarding the heatsink design and the flow direction. In simulation, flow with the inlet centered above the heatsink result in considerably lower pressure drop and slightly higher temperatures than flow through the block, for heatsinks with fin arrays.Creating a competitive product in this product segment certainly seems possible, as there are performance-increasing changes to be made that seemingly has little impact on the production cost.

In this final thesis two simulation models have been integrated. The simulation models are models of JAS 39 Gripen?s fuel system, software and hardware. The time consuming and costly work to develop software has made the department of fuel system to build two models in Xmath/Systembuild. The software model also simplifies the comprehension of how the software in the control computer of the fuel system works.

Computer and videogames has increased rapidly over the past few decades and today a majority of the Swedish population enjoys them on a daily basis. When there are many users, it becomes important how the media chooses to portray the medium because it can affect how the society judges and looks at computer- and videogames.The purpose of this essay is to look at how the portrayal of computer- and videogames has changed in Swedish Newspapers during the period 1994-2014. How the player is being portrayed is also relevant. The method was the discourse analysis founded by Laclau andMouffe and the material was chosen from the two biggest newspapers in Sweden, Dagens Nyheter and Aftonbladet. Theories that were used in the analysis were mainly framing, cultural studies, moral panics and theories based on gender.The result shows that there has been different kinds of portrayals of computer- and videogames from the beginning, though it was mostly negative in 1994 and 2004.

En säker informationskanal med hög överföringskvalitet krävs i dessa dagar när informationsöverföringen ökar för varje år som går. Det finns olika sätt att skapa detta. Antingen genom att se till att överföringsmediet är av mycket hög kvalitet eller att skapa en skyddsmekanism som gör att de överföringsfel som kan uppstå kan detekteras och även korrigeras om man önskar detta. Denna uppsats handlar om detta, att kunna detektera och korrigera fel. Denna gren inom matematiken kallas kodningsteori.Uppsatsen presenterar grunden för kodningsteorin, för att sedan presentera några vanligt förekommande kodningsalgoritmer, Hamming koder, BCH koder, Reed-Solomon.

A computer model based on minimization of the free energy, capable to predict contact angles and spreading transitions between Wenzel and Cassie mode for drops placed on surfaces with different topography were implemented in matlab. Simulations were compared with experiments documented in the literature. These showed that reported transitions between Cassie and Wenzel mode can be explained by minimization of the free energy. In this report, a study on the possibility of constructing water repellent paper surfaces with a combination of treatment with octadecyltrichlorosilane and topography changes, is included..

This thesis describes a system for dealing with free surface fluid simulations, and the components needed in order to construct such a system. It builds upon recent research, but in a computer graphics context the amount of available literature is limited and difficult to implement. Because of this, the text aims at providing a solid foundation of the mathematics needed, at explaining in greater detail the steps needed to solve the problem, and lastly at improving some aspects of the animation process as it has been described in earlier works. The aim of the system itself is to provide visually plausible renditions of animated fluids in three dimensions in a manner that allows it to be usable in a visual effects production context. The novel features described include a generalized interaction layer providing greater control to artists, a new way of dealing with moving objects that interact with the fluid and a method for adding source and drain capabilities..
