This thesis discusses model based tracking of radar echoes in tanks with liquid content. The errors in the measurements are not always random in these cases, and the interference that occurs when nearby echoes moves in relation to each other makes tracking difficult. The tracking problem can be broken down to four parts; track initiation, track destruction, association of the measured echoes to the tracks and to update the tracks with the associated echoes. The radar measurement is primarily made on the surface. However, additional echoes from the tank floor or other structures and double bounces are normally present.

AimThe purpose of this study is to compare the level of activity between playing wii Sports Tennis and wii Sports boxing, and the usual sports, and to see how the two variants are perceived.Issues:- How much strain ratio and energy consumption it gives to exercise wii sports compared with the playing of sport for real?- How do the test participants experience the different tests?- How are the two wii sports games against each other in terms of activity and fitness in the school environment?MethodThis is an experimental study in which 10 test participants (5 men and 5 women) have carried out four different physical tests. The tests consisted of either playing an exergame or playing a sport for 25 minutes. Physical activity was measured during the test using a heart rate monitor. All test participants completed all tests in the same order.

3D-modelling in AutoCAD This thesis is done in cooperation with LB-Hus in Bromölla, and have aimed to establish a digital AutoCAD model of one of the company?s house types and to find out what opportunities there are to do visualisations in the form of images directly from the programme. Modeling has been carried out so that the very construction of the house is included. Interiors and installations, with the exception of the ventilation system, have been left out in the model. The model has been created with solid models after a comparative study made between solid models and surface models to find out which option in this case was the easiest to handle and took up the least space.

Individer som utövar någon typ av sport utsätter sig för både psykiskt och fysisk påfrestning. Denna påfrestning kan vara något som stressar individen och måste därför hanteras och bemästras på något sätt.  Syftet med studien var att undersöka vad som motiverar hobby- respektive professionella ryttare, finns det någon skillnad i upplevelsen av motgångar i sin sport mellan hobbyryttare och professionella tävlingsryttare, och om grupperna har olika sätt att bemästra motgångar. Deltagarna var 11 kvinnor, fem professionella ryttare och sex hobbyryttare. Analysen gjordes genom meningskoncentrering, där olika teman utformades efter studiens frågeställningar.

This thesis compares four relevance feedback methods. The Rocchio and Ide dec-hi algorithms for the vector space model and the binary independence model and Okapi BM25 within the probabilistic framework. This is done in a custom-made Information Retrieval system utilizing a collection containing 131 896 LA-Times articles which is part of the TREC ad-hoc collection. The methods are compared on two grounds, using only the relevance information from the 20 highest ranked documents from an initial search and also by using all available relevance information. Although a significant effect of choice of method could be found on the first ground, post-hoc analysis could not determine any statistically significant differences between the methods where Rocchio, Ide dec-hi and Okapi BM25 performed equivalent.

The report aims to describe the austenitic stainless steel Sanicro 25 from a thermomechanical point of view. The thermal and mechanical properties of the material make it suitable for use in coal ? and thermal power plants. By the use of Sanicro 25 it would be possible to bring the efficiency of these plants up while bringing the carbon emissions down.A material model is created from material testing and validated through simulation in the finite element software Abaqus. The model that has been derived describes the material behavior during loading and stress relaxation for the first cycle in a thermomechanical fatigue test well.

Tyr ? A historical and comparative study of configurations and formations connected to the Old Norse god Tyr. Klas af Edholm This thesis has two aims. One is a discussion of the history of the study of Old Norse religion and related aspects, centered on how general tendencies within the area of research have affected the interpretations of the god *T?waz/Tyr.

The aim of this study was to develop a load prognosis model for Uppsala district heating system to be used as a tool for heat production optimization. The methodwas to build three models for the different customer types; housing, industry andoffices and then scale them for the total system using data from Uppsala districtheating system. The heat load consists of two parts, one that is temperaturedependent and one that is dependent of the social behavior of the customers. Thetemperature part was modelled with an ARX model using an outdoor temperatureprognosis as input signal. The social behavior part was modelled using the mean ofthe social behavior from some days before and additionally by distinguishing betweenweekdays and weekends.

This thesis is concerned with investigating the Roma, a group that is left out in most of the territory bound theories. The theoretical purposes are to develop theories that increase the understanding for the Roma as a diasporic nation without state and the advocacy networks they are organised in. The main empirical purpose has been to study two organisations as cases and how they position themselves against the European Union concerning identity politics. The two organisations are European Roma Rights Centre (ERRC) and Dzeno. They are a part of the same network that works on different levels with the rights of Roma.

This Masters thesis concerns epistemology in Knowledge Organization KO, as a field of study in Library and Information Science LIS. Using a theoretical model by Birger Hjørland and foucauldian discourse analysis as springboards, this study analyses three epistemological discourses in the practice of KO. The aim of the study is to show how these discourses are constituted and demarcated in relation to KO, as well as to examine how they fit into Hjørlands model. A brief historical outline of some epistemological trends in LIS is sketched, as well as examples of how different epistemological schools influence different parts of KO, e.g. information retrieval, indexing- and classification theory.

Simulation is a vital tool during development of JAS 39 Gripen, since money and time can be saved.The Auxiliary and Emergency Power System, AEPS, is a subsystem of the secondary power system in Gripen. It has the function of providing the aircraft with electrical and hydraulical power before activation and after deactivation of the main engine. The system also functions as backup in case of a safety critical problem in the main power supply system. The system basically consists of a control unit and an auxiliary gearbox. The gearbox is driven by an air turbine.

This study examines if the prediction of cardiovascular disease in hypertensive patients can be improved upon when renal function and microalbuminuria are added to the classical risk factors The predictive capability of a model is measured by discrimination, calibration, reclassification and Harrell's C.The results are ambigious. In most cases, microalbuminuria should be included in the model, but the results regarding the other measures of renal function are varied. Therefore, the selection of risk factors to include in the model depends on which measure of prediction one prioritizes..

This paper discusses if Margin of Appreciation is compatible with the idea of universal human rights. Through the case of Negative freedom of association in Sweden, it studies the phenomenon that Giorgio Agamben has called the State of exception.The questions that are discussed and answered are 1) How does the rights theories of Jack Donnelly and Ronald Dworkin relate to Margin of appreciation, and 2) How has Margin of appreciation been applied in cases concerning the negative freedom of association in Sweden, in the European court for human rights. These questions and answers are then used in the discussion on how Margin of appreciation affects the concept of universal human rights. .
