WebGL is a standard for drawing graphics in a web browser. Currently it isn?t widely understood how consistently WebGL performs across a majority of the de- vices that support it. Determining if an image looks correct to a human observer is an interesting problem. The solution for this is useful when developing WebGL applications, since a developer could make better informed decisions during de- velopment.

In today's society, the availability of energy plays an integral part in our everyday lives. Unfortunately, the price of energy in Sweden has increased in recent decades. A large part of our energy consumption goes to heating modules for houses, where heating methods that depend on energy sources such as electricity, district heating, fuel oil, gas and biofuels are the most common ones. During the winter period, the increase in energy costs becomes significantly evident, especially for small property owners. This increase in energy cost is most noticeable for home owners with electric heating.This thesis is written at the Halmstad University, in cooperation with a company, which makes parts of this thesis confidential.

This report is introduced with a presentation of fundamental electromagnetic theories, which have helped a lot in the achievement of methods for calculation and design of microstrip transmission lines and circulators. The used software for the work is also based on these theories. General considerations when designing microstrip solutions, such as different types of transmission lines and circulators, are then presented. Especially the design steps for microstrip lines, which have been used in this project, are described. Discontinuities, like bends of microstrip lines, are treated and simulated.

In this thesis a possible cost effective runner change of some of the units in the hydroelectric power station Olidan is investigated. The possibility to drive a unit at the same efficiency point through a change of the turbine shaft speed and the rate of discharge is tested. Furthermore the theories behind model testing, determination of efficiency increase from model to Prototype and efficiency measurements shall be discussed and analyzed with Olidan as a starting point.A predicted curve has been built on information from model tests and field measurements on the existing runners and runner data from the test of the new model. The predicted curve shows the difference in efficiency between an existing runner and a modern one. It is the difference in efficiency that is used in the calculations that are to show whether changing to a pair of new runners will be cost effective or not.

This thesis has been carried out within the bachelor program for mechanical engineering at Karlstad University in collaboration with BAE Systems in Karlskoga. The purpose with this work was to design a mechanism and associated parts for loading and unloading of shots between primary and secondary magazine in BAE's new 40mm's ship gun.Parts designed or redesigned among other things a transfer mechanism for shot at loading and unloading, well as a hatch mechanism which makes the shots do not fall out of the primary magazine when making separate use. Various important details have been designed to maintain a good functionality of the mechanism.The construction work has mainly been carried out in the CAD software Solid Edge and its associated FEM module. The construction work has also been carried out on rough calculations for constructed details in order to ensure that they meet the stringent requirements of military use in tough marine environment. Two of the most critical parts of the structure where analyzed with the FEM module for estimating the stresses in the material at the applied load.The final design, which is a result of the thesis, meets the requirement specification and the set targets.

This thesis describes the evaluation of a Prototype (Illustrator) for future simulator training of Within Visual Range - combat in the Swedish Air Force. The main focus was to collect and transform user acceptance data (expert opinions) to useful guidelines for continued development. Thirteen active fighter pilots participated in the study. The aim was to use expert opinion to study a) the psychological user acceptance, and b) the technical user acceptance, of the Illustrator together with c) gathering opinions for future improvement. Three psychological aspects were rated before and after the sessions to measure psychological user acceptance.

Background: As a part of a national health control program, Statens VeterinärmedicinskaAnstalt performs diagnostics to screen flocks for certain pathogens causing high mortality,morbidity and/or serious economical losses. There are several viruses in the programincluding IBDV (infectious bursal disease virus), IBV (infectious bronchitis virus) and NDV(Newcastle disease virus). Method: 96 serum samples were collected from different poultryflocks in Sweden and analyzed by ELISA, which are currently used in the health controlprogram as well as by a commercial Prototype of a multiplex immunoassay manufactured byLuminex Corp., which is currently under evaluation at the United States Department ofAgriculture USDA. This 4-plex assay detects antibodies for the three above-mentionedviruses as well as antibodies of avian reovirus. In the context of this study the ELISAs run inroutine diagnostics as well as a REO ELISA were used as the standard for comparison.Result: The antibody concentration in serum from vaccinated chickens was high while theantibody concentration level in serum from not vaccinated chickens was low.

During the autumn of 2007 I carried out an investigation within the bank and finance Sector. The aim of the investigation was to see how informal aspects could be understood in relation to equality within Bank AB? The main question was: Which are the obstacles and opportunities for equality within Bank AB? To answer the main question I asked the following questions to the material: Are there any gender related different within the organization? How are men and women represented within the internal magazine? Which are the conceptions related to sex/gender within the organization? The investigation is based on a survey, the internal magazine was investigated and finally interviews took place. Throughout the investigation I used organization theory in a gender perspective. With the gender organization theory I examined concepts as structures, leadership, symbolism and changes associated with equality.

This master thesis concerns the relation between law and the theory of the conceptual metaphor which has developed within cognitive linguistics. Although its main focus is abstract thinking, it also covers a wide range of aspects within cognitive linguistics, such as the Prototype theory and radial categories. In order to address this relation, three questions will be dealt with. Firstly, does the theory of the conceptual metaphor have relevance to interpretation of legal rules and contracts? Secondly, can the same theory explain why a legal rule or a contractual term has been interpreted outside of its most given area of application? Thirdly, when an interpretation is not predictable from a legal viewpoint, can such an explanation answer to that fact? Answering the first question will require a descriptive analysis of the conceptual metaphor and cognitive linguistics.

This paper deals with the opportunities for the technique of condensation, for wood fired household heaters, on the Swedish market. In this project the condenser is preceded by a scrubber and both energy exchange and separation of unburnt particles have been studied. The facility studied is connected to a wood stove at 30 kW. The tests would show that the effect from the stove never reached above 16 kW. This might be a result of the low temperature of the water going into the stove, from the condenser. In addition to this the wood was not of highest quality and the stove could have needed some maintenance before the tests.

This degree project has been performed with Mega Teknik AB in Landskrona. The project has resulted in a workplace for the cable installers of Mega Teknik. The workplace contains a workbench and a cart.The first stage in this project was to make an analysis of the current workplace to identify the needs the installers had.The different principle construction proposals of how the workbench would look like and which functions it would have was made during brainstorming, in groups and alone. These proposals were compared against each other using a functional analysis that has been put up to get the principle construction that fulfilled most points in this analysis.The proposal chose for further work was a cart and a bench with a module intends, the table got a formulation that creates a better reach for the installers.This proposal was generated in Catia V5 to get a better overview of the suggested proposal.During the primary structure phase drawings over all the products were made and the components were chosen. Calculations were made and the product got the dimension required.

In healthcare settings, administrative routines have been made more efficientthrough digitalization of information and the introduction of stationary computers.This situation is especially true when it comes to radiology, where pictures,referrals and patient information now is completely managed by advanced stationarycomputer systems. However, studies have shown that these rationalizationsdo not support flexible and mobile work routines.PocketRIS is a Prototype illustrating a mobile terminal for radiology that hasbeen designed to simplify workflow and reduce the cognitive workload of healthcarepersonnel. PocketRIS includes a visualization of the clinicians work situationincluding a personal referral list that can make the user attentive of importantevents.Contextual Design has been used to elicit the basic system requirements for thesystem; 19 contextual inquires was conducted with physicians, nurses and assistantnurses at two different radiology clinics in Sweden during six days. The purposeof the study was also to identify the groups that have the greatest need for amobile terminal. The study was concerned with design and evaluation of differentsolutions with healthcare personnel.The result shows that physicians and assistant nurses have the greatest need ofa mobile terminal.

The project was carried out in cooperation with the department of product development IOS at IKEA. The work included improvements of a new existing product that Ikea soon will release on the market, Observatör, a wall bracket for flat screens. The product is supposed to fulfil the needs within this market for IKEA. However, since Ikea was not satisfied with it, our work was to carry out the improvements that were specified in the beginning of the project. Another task in the project was to develop a side-product that is supposed to be used together with Obeservatör for storage of DVD/decoders.The project included labour as problem definition to final technical drawings and a Prototype.

Flow measurement is one of the greatest challenges in order to calculate efficiency in hydropower. Most hydropower plants in Sweden use differential pressure methods for flow measurement. These methods are dependent on constant conditions in the waterways. A change in these conditions, like turbine improvements, prevents differential pressure methods to verify efficiency improvements. Since efficiency improvements can?t be verified by one measurement system, another method, which isn?t affected by changing conditions, can be used.
