Sammanfattning:De ökande testdatavolymerna som krävs för att testa moderna System-On-Chip (SOC) bidrar i hög grad till den ökande produktionskostnaden. De stora testdatavolymerna kräver stora och dyra Automatic Test Equipment-minnen (ATE-minnen). För att minska behovet av dessa minnen så har olika komprimeringsmetoder utvecklats.Denna rapport beskriver arbetet med att implementera en given komprimeringsmetod för testdata till SOC. Den metod som används heter vector repeat och den implementeras genom skapandet av ett för ändamålet avsett dataprogrogram. För att vector repeat ska fungera effektivt så förutsätts det att in- och utgångarna på den ATE som används kan delas in i olika portar.

Heavy duty vehicles often have problems with traction during the winter periods. For vehicles that can lift tag axles it is possible to increase the normal force on the driven axle by lifting one or more tag axles, this will then increase the propulsive force of friction. This however increases wear on both road and vehicle. A possibility to reduce the wear while achieving nearly equivalent traction compared to lifted tag axles is to allow the vehicle to regulate the normal force by lowering the pressure in the air suspension associated with the tag axles or by the lifting of these axles. The vehicle would then by itself be able to set just the right amount of normal force on the drive wheels to avoid unnecessarily high normal forces while maintaining sufficient traction.The purpose of the report is to find out which parameters affect heavy duty vehicles when driving on slippery slopes and how traction can be improved.

In this master thesis a robot arm belonging to an Automatic milking machine from DeLaval is investigated. The robot arm is controlled by a pneumatic cylinder and a valve. The goal of the master thesis is to investigate instability problems and to find out if it is possible to solve them by using gain scheduling. Gain scheduling is a type of controller where the parameters of the controller are changed during operation, for example depending on the working point. First a nonlinear mathematical model of the system was made.

The aim of this thesis is to examine the possibilities and challenges facing an archive, Svenskt barnbildarkiv (SBBA), if to publish its material online. Our context for this study is image indexing. Our main questions are: How can SBBA index their pictures for a possible publication on the Internet? Are there any pros or cons in the determination of topics in children?s images, and in that case, which? What search paths are important when indexing children?s pictures, and why are they important? To answer these questions, the thesis is built on a wide study of interdisciplinary literature. But also on SBBA: s own handbook for image ?registration?, and on interviews with the persons working at the archive SBBA, in Eskilstuna.

Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as Automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.

This Master?s thesis examines different retrieval strategies used in cross-language information retrieval (CLIR). The aim was to investigate if there were any differences between baseline queries and translated queries in retrieval effectiveness; how the retrieval effectiveness was affected by query structuring and if the results differed between different languages. The languages used in this study were Swedish, English and Finnish. 30 topics from the TrecUta collection were translated into Swedish and Finnish.

In this thesis, a computer program that in a simple way can calculate the performance of control loops at the refinery Preemraff Lysekil has been created. The computer program has been adapted to the environment at Preemraff Lysekil. Theories for evaluation has been studied in aspect of reliability and of Automatic implementation. The evaluation has been carried out from data collected directly from control loops at the refinery and from simulated control loops with implemented errors. Among the studied methods are Harris index and Stattin´s oscillation index.

This degree thesis is based on an assignment from BEOMAT in Storfors. BEOMAT is a company that constructs and sellsclay pigeons to both the national and international market.Our main purpose with this paper is to find a solution/system that can replace the expensive and space demandingOlympic trap facility. Our solution will replace fifteen clay pigeon throwers with one Automatic thrower whosimulate all throwers together. The system will be provided with an appropriate control system for mass productiontherefore this system needs to be user-friendly so no previous knowledge is required.Totally 405 different throw coordinates will be stored in the programme in nine different subprograms. According tothe Olympic-rules the throwers should coincidence within certain specified conditions, this will be solved with anrandomizer in the programme.

The aim of this master ´s thesis is to understand why there are difficulties in finding joint methods and standards in the field of image indexing. The main focus for interpreting these issues is on Sara Shatford ´s article Analyzing the Subject of a Picture: A Theoretical Approach. In the article Shatford discusses a theoretical basis for identifying and classifying the subject in a picture. In doing so she uses concepts taken from The Philosophy of Art, Meaning in Language and Visual Perception. With the aid of S.R.

This study was performed in collaboration with Moelven Skog AB, Örebro district. The purpose of the study was to review existing literature in order to describe the current status of harvester based measurement technology as the way to provide information for calculating payment to the forest owners. In addition to this, a short survey was conducted to find out how a switch to harvester based measurement would affect the administrative workload on timber purchasers working for the district. The literature study shows that the harvester measurement technology is ready to use if it is combined with well-established routines for control of the harvesters, methods for Automatic quality indexing of the timber and ways of creating pricelists specially adapted for harvester measurement. Pricing each stem seems to be the most promising method. Stem pricing has several benefits.

The project team has chosen to carry out the project itself. This is to be able to work more flexibly in the product development process and not be guided by some guidelines.Every day, we read in the media about a new truck burglary. The problem has become so common that we do not even notice it in the media. Each year the theft of 1 billion of Sweden and the entire 82 billion in Europe in 2008. This is an increase of 10 billion by 2007.

Protein is an important component in various milk products and has a crucial role in the final quality. Excluding non-protein nitrogen, bovine milk contains about 3.3% protein whereas about 80% of this fraction consists of casein. There are four major members in the casein family: ?s1-casein, ?s2- casein, ?-casein and ?-casein. Proteolytic enzymes are the cause of degradation of the economically important milk proteins.

Examensarbetet som beskrivs i denna rapport handlar om en ny teknik för att förbättra säkerheten för flygplan i luften och i närheten av flygplatser. Denna teknik benämns ADS-B (Automatic Dependent Surveillance Broadcast), och är tänkt att göra det möjligt för piloter att själva få information om trafik i närområdet. Nuvarande system baserar sig i huvudsak på visuella observationer från flygledare i kontrolltorn samt radarspaning omkring flygplatserna. Med det nuvarande systemet kommer det att bli både dyrt och svårt att upprätthålla en acceptabel nivå på flygsäkerheten när trafiken ökar. Arbetet har bedrivits i AerotechTelubs regi i Linköping samt med hjälp ifrån företaget Sectra Wireless Technologies AB.
