Ocean Thermal Energy Conversion, OTEC, a technology using the temperature difference between cold deep seawater and warm surface water, can extract the work in the form of electricity. OTEC gives also synergies of drinkable fresh water. The temperature difference has an impact on the efficiency of the technology, which means that the feasibility of OTEC is geographically limited. The project intends to explore the possibility of replacing the atoll Tarawa?s present electricity generation with an OTEC plant and to explore synergies. In the present situation all of Tarawa?s electricity is generated by fossil fuels.

Under de senaste åren har webbplatser blivit allt mer komplexa och informationen som ska visas och hanteras allt större. För att underlätta hantering och administration av dessa system har många CMS-system vuxit fram. Dessa system kan skilja sig mycket beträffande pris och funktionalitet, allt från mindre open source system till stora komplexa kommersiellt drivna system. Detta arbete bygger på att skräddarsy ett CMS-system för administration och hantering av innehåll på diverse artist sidor, som hanteras av ett medieföretag. Systemet använder tekniker som JavaScript, PHP, MySQL som grund för dess uppbyggnad.

AbstractMaster Thesis in business administration, School of Business and Economics at the Linneaus University, financial control, spring 2010Authors:Stefan Hellman and Ewa Warnquist Supervisor:Magnus Willesson Title: Reward systems - a study of public companies? variable compensation system Background:Our interest of the variable compensation system in public companies was brought by the recent extensive discussions of bonuses in the time of a financial crisis. This has led to that the word bonus has been given a negative connotation and we wanted to find out how the system of variable compensation is structured in the companies at Stockholm Stock Exchange. Problem:How is the variable compensation system structured in public companies? Purpose:The purpose of this paper is to study how the variable compensation in public companies is structured.

This thesis focuses on the perception of immigration and refugees in the commonEuropean refugee and immigration policy. It identifies different discourses andstudies their development and interrelated power structures.Using the discourse theory of Laclau and Mouffe, documents from theEuropean Council, the Commission, the Justice and Home Affairs Council andParliament debates are analysed. The study is defined in the time span of 1999-2006, i.e. from the European Council's first agreement on developing a commonEuropean asylum system, following the period up till today.Four discourses are distinguished, focusing respectively on rights, security,European Union's needs, and cultural identity. I use Sandra Lavenex theory ofrealism and idealism to analyse one of the main points in the thesis: There is afundamental schism between the one rights-based discourse, focusing on universalhuman rights, and the three sharing a particularistic focus on immigration as asecurity concern.

The report is the result of a master thesis at ENEA AB during the fall of 2009. Itaims to create a specification of flash memory management system which focuseson power efficiency and low RAM usage for embedded systems, and to design andimplement a prototype of such a system to facilitate further development toward thecreated specification. The system used by ENEA today is a Flash Translation Layer(FTL). It has a complex structure which prohibits modifications and customization,therefore a new flash memory management system needs to be developed.The suggested solution uses a translation layer called Metadata FTL (MFTL), wherefile system metadata and userdata are separated from each other in order to improveperformance. The partition holding userdata uses a block-level mapped translationlayer system called Fully Associative Sector Translation FTL.

Voice over IP (VoIP) is a relatively new technology that enables voice calls over data networks.With VoIP it is possible to lower expenses, and increase functionality and flexibility. FromSwedish Armed Forces point of view, the security issue is of great importance, why the focus inthis report is on the security aspect of the two most common open-source VoIP-protocols H.323and SIP, some of the most common attacks, and counter-measures for those attacks.Because of the level of complexity with a network running H.323 or SIP, and the fact that it hasyet to stand the same level of trial as of traditional telephony, a VoIP-system includes manyknown security-issues, and probably at present many unknown security flaws.The conclusion is that it takes great knowledge and insight about a VoIP-network based onH.323 or SIP to make the network satisfyingly safe as it is today, and is therefore perhaps not asuitable solution for the Swedish Armed Forces today for their more sensitive communications..

Banverket Produktion är Sveriges största entreprenör inom järnvägsunderhåll. De har tillgång till ett flertal IT-system som ger information om järnvägsanläggningar och maskiner. Banverket Produktion vill utreda möjligheterna med att kombinera denna information och presentera den i ett kartgränssitt.En kartapplikation kan användas för att ta fram information ifrån olika system och presentera grafiskt. Den kan även användas som ett gränssnitt för att söka information från andra distrikt. Genom att använda sig av grafisk kartvisning av verksamhetsinformation blir det möjligt att planera åtgärder på ett mer tidssparande och kostnadseffektivt sätt och maskiner kan utnyttjas effektivare.Arbetet har gått ut på att beskriva vilken ökad verksamhetsnytta grafisk kartvisning av verksamhetsinformation kan ge och presentera ett förslag på en systemarkitektur som stödjer grafisk kartvisning.

Examensarbete har utförts för AIAB DC Systems i Karlstad.Vår uppgift gick ut på att göra ett övervakningssystem för DC-system. Enheten skall användas för att övervaka isolerade DC-system avseende spänningsnivåer och isolation samt larma vid fel. Tidigare har man haft ett analogt system ute på marknaden men nu vill man ha ett digitalt processorbaserat system.Vi har använt oss av en 8-bitars RISC-processor. Programmeringen har gjorts i assembler med hjälp av ett utvecklings-kit och sköter logiken för övervakningen. Programmet manövreras med två tryckknappar och en display.Programmet vi har tagit fram behöver kompletteras med vissa funktioner.

A today common soil reinforcement method is the installation of lime-cement columns. Lime-cement columns have been used since the 1970?s and have been a useful method for stabilizing soil at great depths. It is mostly used for stabilizing road and railway embankments because the method is economically viable and the columns are easy to install. The total costs for the installation of the lime-cement columns is dependent on the numbers of installed columns, what percentage of lime and cement that has been used and the pattern in which the columns has been installed.

The aim of this thesis is to create an understanding of nurses' information practices. To be able to search, find, use and critically evaluate information is important, not just during studies, but also in professional life. This study is intended to deepen our understanding of nurses ' information literacy in a workplace context.The main questions are: What information do nurses need on a daily basis and how do they experience information activities? What factors determine the sources they use? Do information practices vary in the workplace? Do nurses? professional experiences impact on their information practices? Nine nurses were interviewed using semi-structured interviews. The interviews have been analysed through a hermeneutic approach.

This report describes the development of a system for controlling documents. The report starts with a problem description which the company wants an intranet-based solution for. The report then continues to describe the development phase for the different parts of the system which results in a complete system. The company that wanted this system is called Orbit One and is located in Ronneby, Sweden. They have had a problem with old documents circulating in different versions and in different binders. Now thanks to their new system they can access their documents easy and on demand through their intranet..

The aim of this master thesis is to evaluate the performance of the content-based image retrieval system ImBrowse from a semantic point of view. Evaluation of retrieval performance is a problem in content-based image retrieval (CBIR). There are many different methods for measuring the performance of content-based image retrieval systems, but no common way for performing the evaluation. The main focus is on image retrieval regarding the extraction of the visual features in the image, from three semantic levels. The thesis tries to elucidate the semantic gap, which is the problem when the systems extraction of the visual features from the image and the user?s interpretation of that same information do not correspond.

Vi har utvecklat ett tidregistrerings- och faktureringssystem åt Xeratech Systems AB i Karlstad. Målet med vårt arbete var att utveckla ett system som var mer användarvänligt och mer funktionsenligt än Xeratechs gamla system - XSIS. Huvudfunktionen med systemet är att kunna registrera tider som anställda på Xeratech arbetat på olika projekt, vilket sedan ska kunna sammanställas till fakturor. Vi har skrivit en kravspecifikation för systemet efter diskussion med Xeratech, och sedan implementerat tidregistreringsdelen av specifikationen. Resultatet av vårt arbete är ett väl fungerande system som fått positiv respons vid testkörning hos Xeratech.

This final year project is dedicated to investigate the problem domain of system maintenance management. The purpose is to find problems in the system maintenance management of today. Whether there is any problem that can be elicitated in the requirements engineering?s phase that could help to obtain more maintenance management friendly systems and if it is not possible to obtain more maintenance management friendly, what else can be done?It has been learned that there are many problems today in the problem domain and the most great ones are the system documentation, stress and a systemknowledge lack among developers, system managers and system users.The requirements that have been found for this problem is good documentation, and use of simple solutions in the creating of the system..
