In this thesis, two real-time stereo methods have been implemented and evaluated. The first one is based on blockmatching and the second one is based on local phase. The goal was to be able to run the algorithms at real-time and examine which one is best. The blockmatching method performed better than the phase based method, both in speed and accuracy. SIMD operations (Single Instruction Multiple Data) have been used in the processor giving a speed boost by a factor of two..

In this study, the sea trout (Salmo trutta) spawning migration was studied in the river Själsöån, Gotland, to assess the main external factors determining upstream migration and seasonal changes in fish parameters. Additionally population trends were studied by examination of old data. The most important external factors for upstream migration were the air pressure, air temperature and wind direction. No significant difference was found between when males and females migrated upstream. Larger females in better condition started migration earlier than the smaller females in poorer condition.

There is an increased pressure for firms to provide the financial market with additional information. Such disclosure is attached with different kinds of costs. In spite of these costs, and in spite of increased mandatory disclosures, firms choose to voluntary disclosure financial information to analysts and others. This indicates that firms also benefit from providing additional information. The subjects of this study is 431 annual reports from firms listed at the Stockholm Stock Exchange for 2002 and 2005 and the objective is to survey factors that can explain variations in firms? voluntary disclosure.

The Swedish coastal defence took on a whole new meaning after the introduction of the coastal artillery in 1902. The establishment of the coastal artillery meant that the Swedish military had access to a whole new military branch, in addition to the Army and the Navy. Under the direction of one general, two regiments were established. One in Vaxholm and the second in the naval city of Karlskrona. The aim of this essay is to investigate how the Costal Artillery were established, by analyzing the parliamentary of the year 1901.

Syftet med denna studie var att klargöra eventuellt samband mellan nutrition och trycksår genom att söka svar på de tre frågorna: Har nutritionen någon betydelse för uppkomst och läkning av trycksår? Vilka näringsämnen behövs för att förhind-ra uppkomsten och främja läkningen av trycksår? Finns de något samband mellan malnutrition och/eller ätsvårigheter och trycksår? Metoden för denna litteraturstu-die innefattade systematisk databassökning och manuell sökning av artiklar från referenslistor. Tio vetenskapliga artiklar med kvantitativ forskning i ämnet har analyserats och sammanställts. Resultatet presenteras i följande fyra tema: Nutri-tionens betydelse, energiintagets betydelse, vitaminers och mineralers betydelse samt bifynd. Analysen indikerar på samband mellan förbättrad nutrition och både minskad incidens och förbättrad läkning av trycksår..

The problem presented in this report is that of finding a method to calculate the lift force from a single-element airfoil of arbitrary shape. A number of restrictions are used in order to simplify calculations while retaining reasonable accuracy. The problem is solved for the two-dimensional case only and no finite-wing effects are taken into account. Furthermore, inviscid and incompressible flow is assumed. The method used to solve the problem is the vortex panel method, with vortex singularities distributed over simplified airfoil geometry.

This thesis is based on a case study of the City of Stockholm. The study aims to explore the effects on the city's large investments caused by the public reform. Furthermore, the question concerns the character of the impact and if it will affect what type of investments that will be prioritized. The theoretical background is based on Brunsson's ideas about political organizations shifting towards corporate nature, and Almqvist's interpretation of New Public Management (NPM). Moreover, models explaining public management reform, and the main components of corporate shifting, are used.

Avsikten med detta examensarbete är att utreda möjligheterna för och föreslå lämplig bebyggelse i Västra Sörhaga, Alingsås. Vid en första anblick ser Västra Sörhaga ut att sträcka ut sig över ett mycket stort område. Men Västra Sörhaga begränsas också av flera faktorer. Jag kommer i detta arbete visa hur den byggbara marken för bostäder reduceras av olika omständigheter och hur dessa kan återerövras..

Examensarbetet belyser problematiken kring den offentliga konsten och hur den offentliga konsten bättre kan integreras i den kommunala planeringens beslutsprocess med hjälp utav en analys- och samarbetsmetod. Delar av analys- och samarbetsmetoden genomförs i fyra fallstudier i Eskilstuna och Uddevalla..

I en värld där kraven på flexibilitet, säkerhet och hårdvaruoptimering är nyckelfaktorer när det kommer till att välja IT-miljöer för företag blir virtuella skrivbord mer och mer poulära. Med dessa miljöer finns det också problem när det kommer till användarupplevelsen om nätverket ifråga inte kan uppfylla de krav som ett sådant system ställer. I detta arbete undersöks implikationerna vissa nätverksvariabler kan ha för en Virtual Desktop-infrastruktur, VDI. För att belysa dessa problem har två tester utförts på en VDI miljö. Det första testet gick ut på att mäta latensen då skrivbordsmiljön renderades för klienten från virtualiseringsservern vid olika nätverksdiamterar.

Environment friendly transports are one of the main topics in the industry and society today.Shell organizes an annual university competition called Shell Eco Marathon. The goal is to buildthe car that consumes the least fuel during a race. KTH participated for the first time in 2006.The engine for this competition, DoubleTwo, has been developed within the school. Theprinciple is a two stroke counter piston HCCI engine with variable compression ratio. HCCIstands for homogenous charge compression ignition.

To succeed, and make money at your animal production you need to feed your animals with high quality fodder. Other condition to succeed is that you keep your production costs at a minimum. To be able to produce baled silage at a low cost it?s very important that the bales have a high density. Density is measured in kg dry matter (DM) per cubic meter. The purpose with this report was to learn more about making silage in round bales and to how much the bale density varies between different brands of round balers.

This article seeks to re-imagine the Alandish hembygdsrätt to a regional citizenship. Hembygdsrätt is a judicial tool that regulates acquisition of property and voting rights. Its a central part of the autonomy as it constitutes a social-border between Finns and Alanders.However as Åland and Finland became members of the European Union questions arouse concerning the legitimacy of the current statues. The community argued that it could be considered as a breach of the anti-discrimination principle. Therefore Alandish autonomy was recognized as an exception in the joint-accession treaty of Finland and Åland.

Den senaste tiden har intresset kring ekologisk bebyggelse vuxit. Passivhus är en teknik som växte fram under 90- talet och som pressenteras som ett miljövänligare och effektivare alternativ till modern regelverksbebyggelse. Men är det egentligen så? I den här uppsatsen används teorin om ekologiska fotavtryck för att presentera, resonera kring och jämföra de båda byggteknikerna. Utöver detta pressenteras ett planförslag för exploatering av området Himlabacken i Vetlanda..

Public procurement stands for a substantial part of the total food consumption in Sweden. The majority of the procured food is today imported and according to market trends it?s intended to stay that way. Imported food is favoured for locally produced due to price pressure. Consequently domestic pork farmers have declined by 25 percent during the last twenty years.
