This thesis has identified and studied measures to allow for reduced use of electricity in a waste incineration plant in western Sweden. The energy extracted from the waste at the powerplant is utilized and sold in form of electricity and heat. Technical and environmentally the combined heat and power plant is by today's standards among the leading waste incineration plants in the world. The owners are constantly striving to improve the efficiency of the waste incineration plant. They have seen the opportunities for savings in reducing internal usage of electricity.

GPGPU is a collective term for research involving general computation on graphics cards. A modern graphics card typically provides more than ten times the computational power of an ordinary PC processor. This is a result of the high demands for speed and image quality in computer games.This thesis investigates the possibility of exploiting this computational power for image processing purposes. Three well known methods where implemented on a graphics card: FFT (Fast Fourier Transform), KLT (Kanade Lucas Tomasi point tracking) and the generation of scale pyramids. All algorithms where successfully implemented and they are tree to ten times faster than correspondning optimized CPU implementation..

The purpose of our study is to examine whether stress among social workers is present, and ifso, what strategies they and their supervisors use to manage work-related stress. The study isbased on a qualitative method. The data consist of interviews, with six social workers andthree supervisors. The study?s theoretical framework is based on KASAM, SOC-sense ofcoherence by Antonovsky, demand- control- support model by Karasek & Theorell, stresstheory by Hans Selye and coping strategies by Lazarus.

Metoder används idag i princip vid all utveckling av informationssystem. Undersökningar som gjorts visar dock att de sällan följs på det sätt skaparna av metoderna avsåg utan att systemutvecklare av olika orsaker modifierar eller skräddarsyr dessa metoder och därigenom skapar en Method- in-Action. Syftet med denna uppsats har varit att genom kvalitativa intervjuer undersöka systemutvecklarens metodanvändning samt studera vilka faktorer som påverkar när systemutvecklaren skapar en Method-in-Action. Några av de slutsatser vi dragit av denna undersökning är att nyttan tid, storlek, vana, visualisering och trend är faktorer som påverkar sammansättningen av en Method-in-Action och att systemutvecklare oftast använder en eller högst två metoder i sitt arbete..

This thesis discusses main problems associated with dictionary-based Cross-Language Information Retrieval as lexical and translational ambiguity of query terms, translation of compounds and phrases, dictionary limitation. The purpose of the study is to investigate how query structure influences the effectiveness of CLIR regarding performance of three query types: original query, unstructured query and structured query. Query structuring refers to the application of #syn-operator to group query terms. The study comprises an experiment that was performed in the InQuery IR system with TrecUta database that contains 550,000 news articles from different American newspapers. 24 topics were used for the experiment.

The construction of buildings and paved surfaces changes the natural water balance.Precipitation generates surface runoff and storm water instead of infiltrating into the soil.Storm water has come to be considered as a major source of pollution in lakes and streams inthe vicinity of urban areas. Reduction of pollutants in storm water is a key action in order toprotect sensitive recipients and maintain high water quality. Storm water is traditionallytransported by storm sewers to the nearest recipient. In recent years the approach to stormwater management has changed; storm water should primarily be disposed of on site, throughlocal disposal of storm water, LOD. LOD is created by a combination of the function ofseveral smaller local facilities and the general sewer system.

Denna rapport behandlar konstruktion och tillverkning av ett videokort till Versa Module Eurocard (VME) bussen. Kortet skall användas vid laborationer i kurser där mikrodatorkort VM42 från PEP Modular Computer används. Grafikkortet klarar en upplösning på minst 640x480 punkter med 24-bitars färg. Hela konstruktionen är uppbyggd kring Lattice® MACH4A3-384/160. Designen av MACH kretsen är uppbyggd i Very High speed integrated hardware Description Language (VHDL) med hjälp av programmen ActiveHDL, Synplify Pro®, ispDesignExpert samt LatticePRO.

This thesis examines information visualization, infographics, as a method of advertising. To answer the initial research question of what makes infographics an appropriate method for print advertising, a practical infographic-based advertising campaign has been designed. This, together with three other campaigns, has been the basis for an analysis focused on function, appeal and persuasion. The result tells us that there are benefits to using infographics for an advertising purpose, because the method can act both attention-grabbing and convincing, depending on how it is used and designed..

This study examines some students? attitudes towards mathematics in grade 2-4. When studying students? attitudes questionnaires and interviews are often being used as methods. In this study we used a more rare method.

Randomness is a complex area of computer science, where only pseudo random numbers are possible to generate algorithmically.This report presents established algorithms for random number generation by conducting a basic study of relevant literature, while testing distribution and speed of the algorithms contained within the C++11 Random library. The results are compared to the algorithm XORShift and a modified version of it. The study shows that the modified algorithm passes all tests in Small Crush, andthat the run time is shorter than for those in the Random library. The conclusion is that it is possible to, with simple means, modify an algorithm to outperform the algorithms of the C++11 Random library..

The current paper compares the relations between different measures of activity and some common neuropsychological tests. One-hundred and fifty five healthy elderly, aged 55 - 85, living in Sweden were included. Gender-specific patterns were found for both activities and correlations between activities and cognitive measures. The main findings suggest that activities are associated with cognitive speed in men, whereas, for women, active and passive activities correlate, positively and negatively accordingly, with education. In comparison, complex models of activity outperform simpler ones and theory-driven measures just barely outperform intuitive models..

Total organic carbon (TOC) and chemical oxygen demand (COD) are two methods used for measuring organic pollutants in wastewater. Both methods are widely used but the COD method results in production of hazardous wastes, including mercury.The purpose of this study was to validate the method TOC that will replace COD and find a factor to convert TOC to COD. In this study 26 samples were analyzed from four sewage treatment plant in the municipality of Enköping.The results show that the COD method could be replaced by the TOC method.The factor for COD/TOC was between 3.1 - 3.3. Both methods will be used in parallel until 2013 when it will be forbidden to use the COD analysis..

At SLU, Divison of Reproduction, Dept of Clinical Science, there is an ongoing project on the development and evaluation of new methods for the assessment of stallion semen quality. This EEF-study, which is a part of that larger project, has focused on the effects on motility and fertility of stallion semen of two different extenders and selection. Both an objective method and a subjective method for analysis have been used and compared in the study. The increase in the use of artificial insemination with cooled semen in Swedish horse breeding over the last decade is thought to play a part in declining foaling rates (Kareskoski et al, 2006, Kuisma et al, 2006). This calls for better evaluation methods of semen quality since cooling and transportation put higher demands on semen quality in order to maintain fertility (Aurich, 2005).
