Arbetet har utförts på ABB i Ludvika med avsikt att förbättra revisionsprocessenför kontroll och skydd. En revision är en ändring på ett godkänt och klarmarkeratobjekt. Då objektet i fråga redan kan vara levererat till kund och man behöver göraen ändring krävs en strukturerad process för att utföra denna ändring. Processen föratt göra detta är i dagsläget komplicerad och kräver en hel del administrativt arbete.Processen använder sig utav ett antal program för lagring och databaser så som,Lotus Notes, HiDraw Studio, och HiDra32.Avdelningen för kontroll och skydd är i fasen att övergå till ett annat elCADsystem, Engineering Base. Detta är också en av anledningarna att man önskar en nyprocess för revisionshantering.Arbetet bestod till en början av inlärning av den dåvarande processen.

This thesis investigates the possibilities offered to a working landscape architect by anincreased and altered use of digital 3D environments. A basic assumption is that increased useof digital three-dimensional environments promotes the creative processes and presentationoptions of landscape architects.The thesis is based on literature studies and communication with working landscapearchitects, and includes an investigation of the visualization methods available in the Blender3D modelling software. The thesis provides a thorough survey of what it means to model inthree dimensions, as well as of what modelling methods are feasible for a landscape architectto use. As landscape architects, we work with human and unique processes, and thus it isdifficult to develop standardized and automatic software for our profession. One possiblesolution is to turn to open source development, where software and models are shared andanyone can contribute.

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.

Detta arbete undersöker frågan om hur man kan gå tillväga för att skapa en känsla av liv i en postapokalyptisk spelvärld med hjälp av färger, former och animationer i en egen spelproduktion. Arbetet tar upp flera teorier kring spelutveckling, post-apokalyptisk fiktion och färglära. Arbetet tar också upp verktyg som användes i produktionen av det spel som skapades och hur arbetet fortskred. Diskussionen som följer tar upp hur metoderna som användes påverkade resultatet och vad resultatet blev, samt hur man gick tillväga för att tolka det. Slutsatsen som dras i diskussionen visar att det är möjligt att skapa en känsla av liv i en postapokalyptisk spelvärld i en egen produktion och hur man kan förbättra de metoder som använts i en eventuell uppföljning av detta arbete.

This report is a bachelor thesis presented at the department of Computer Science andEngineering at Chalmers University of Technology. The aim for the project is to find a simplemethod to measure and display physical quantities in a three dimensional room.The report describes a method to construct a system for measuring differentphysical quantities via sensors. The system must be built in a modular and expandable way tobe adaptable to different tasks.The system explained in the report consists of two parts;A physical scanner with moveable probes for carrying sensors and a microcontroller forcontrolling the probes and communicating with the next part.An application written in Java for storing the measured values and presenting them in a lucidperspective.It is possible to construct the scanner with different designs and circuitry, with multiplexers andflip-flops, to ensure that an unspecified number of probes can be added to the system and thatthey can be operated simultaneously.The Java application is written in a modular way, using a design pattern that separates eachindividual part of the application. It contains exceptions and interfaces that ensure a safe andexpandable application..

This essay elucidates upper secondary students? literacy practices, (literacy events, literacy competencies and literacy culture) during a typical day, with focus on the daily literacy practices. A literacy ethnographic study conducted in the environment which participants naturally are, at home, at school and in leisure. The study is inspired of a project, Skriftbruk i arbetslivet, ´Literacy Practices in Working Life´, that conducted by Anna-Malin Karlsson, Per Ledin and Olle Josephson, in collaboration with Vetenskapsrådet ´Science Council´(2002-2004).The result of this study shows that students from professional preparing programs not use such literacy competencies that been tested in traditionally reading comprehension test, particularly much. However, do they read a lot during the literacy practices day by television, computer and mobile phone.

Antalet programvaror ökar för varje dag och människor använder dagligen en mängd olika sorters programvara både på datorer och på andra enheter. Det finns idag programvara som kallas för fri och öppen programvara som tar upp kampen med gamla klassiska proprietära programvaror. Öppna och fria programvaror släpper sin källkod helt fri så användaren själv har möjlighet att göra ändringar i den programvara som används medan proprietär programvaras källkod är skyddad och hemlig. Dessa tre olika sorters programvaror jämförs och diskuteras utifrån tekniska likheter och skillnader i denna kandidatuppsats. Syftet med denna kandidatuppsats inom informatik är att undersöka vad privatpersoner som är tekniskt intresserade har för tankar och attityder kring proprietär, öppen och fri programvara och visa vilka tekniska aspekter som prioriteras vid val mellan dem. I undersökningen har ett kvantitativt angreppssätt bestående av en webbenkät som besvarats av privatpersoner tillämpats. Resultatet från denna enkät har tillsammans med den teori som insamlats visat vilka tekniska funktioner och skillnader som påverkar en privatperson då val av olika sorters programvara ska ske. Undersökningen har visat att det som användaren prioriterar högst i en programvara är användbarheten som handlar om hur användarvänligt användargränssnittet är och hur lättanvänd en programvara är.

The purpose of this thesis for Sapa Heat Transfer is to examine a furnace in which aluminium is pre-heated before hot rolling. The project is modeled in a computer environment in which the air flow in the furnace and the heat transfer to the aluminium solids are included. The computer environment and its governing equations, as well as boundary conditions and generalizations, are presented and explained.The simulations are based on two models. The first model has an asymmetric solid placement, which is how it looks in today's ovens. It is validated against collected data.

Intranet is today a common technical groupware to communicate in many organisations. People can interact through the Intranet and communicate within the organization and get relevant information according to their workplace. It can be difficult to get everybody to use the Intranet as an information- and communication tool. This causes problems when people want to reach out with information. With these thoughts we entered our work at Luftfartsverket at Arlanda airport.

Since studies points out declining interest in science among students in Swedish schools, I have in this paper chosen to examine how some students at the Social Science Programme are experiencing the lessons in Natural Science and how to make lessons more interesting according to these students.The purpose of this study was to gain a greater understanding of how teachers would develop new perspectives and tools to make lessons in Natural Science more interesting. I also wanted to investigate whether an intercultural perspective could be a possible tool to increase students? interest and motivation.As a theoretical framework, I have assumed Vygotskij's sociocultural perspective, Habermas's theory of deliberative conversations and an intercultural perspective. Through a qualitative approach, I conducted interviews with students and teachers. The main results showed that students felt that natural Science lessons were too theoretical and undemocratic and that they wanted to have more student interactions, such as discussions and group works.

Det finns flera olika metoder och tekniker för tredimensionell rendering, alla med olika för- och nackdelar som lämpar sig för olika applikationer. Voxelbaserad rendering har använts flitigt inom vetenskapliga områden, främst inom det medicinska för visualisering av volymetrisk data. Tekniken används nu inom flera olika områden för tredimensionell rendering, t.ex. i datorspel, i matematiska applikationer och vid geologisk rekonstruktion. I den här rapporten kommer voxelbaserad rendering med Marching Cubes-algoritmen undersökas för att se hur den lämpar sig för realtidsapplikationer. Området behandlas dels teoretiskt, men även praktiskt då en implementering av Marching Cubes gjordes för att genomföra några tester för att se hur prestandan påverkades. Av testerna framkom det tydligt att algoritmen lämpar sig väl för realtidsapplikationer och dagens grafikkort.

This master thesis has been carried out at Scania R&D at the department of Powertrain Control System Development during the winter 2011/2012. The purpose of the thesis was to produce a method that with the result of troubles codes from the field testing would be able to say something about the maturation of a component, in this case the VGT, variable geometry turbocharger. To start with, it was necessary to investigate hich information was available. After the information been summed up in tables and charts, this so that it was possible to understand the huge amount of data, the calculations started.Since the thesis was about maturation of a component the proportions were calculated of components that had a trouble code in contrast of those who passed the test without a trouble code. This Thesis includes background information about basic of statistics and about the company Scania and its testing process.

Competition of spruce fiber raw materials has increased dramatically in the last few years, leading to the fact that transportation costs in the current situation represents a much larger share of the total raw material cost. The Holmen-owned pulp industry Hallsta Paper Mill's location on the coast also constitutes a problem, because of the lack of raw material, which is much larger there, than for a pulp mill located in the hinterland. For a coastal industry it?s therefore natural to import much of the raw material by boat or to buy it from the timber terminals, in order to maintain good profitability. The purpose of this study was to analyze how the size of Hallsta Paper Mill timber supply area, without competition, with competition and with terminal use, affects the company ?s transport costs.

Energy losses are an essential part of a power grid company?s costs. From anenvironmental and economic perspective, it is important to reduce these costs. Toknow where efforts should be deployed, it is important to have good knowledge ofwhere in the network losses are situated. When creating network tariffs, there is alsonecessary to have a correct distribution such that the network customers that use acertain part of the network, only pays for the network losses in this area.

This thesis deals with one of the main questions within information science: The question about controlled and uncontrolled vocabulary and which of the two that are most effective when it comes to retrieve relevant information from electronic databases. The method used here is literature studies. I have described and examined five empirical studies which has been done in purpose to compare the effectiveness in retrieval with controlled and uncontrolled vocabulary, in the way they are used in retrieval of information in databases. The studies I have examined have also used recall and precision as a value to measure the effectiveness of retrieval. The studies which I have chosen is also limited to deal only with studies that have been done in bibliographic databases.
