A current conveyor is an active building block that can be used to implement most active and passive components. It differs from the operation amplifier in that it uses current instead of voltage. The current conveyor also has significantly higher voltage gain over a broader frequency range. To simplify the construction of analogue circuits and increase the construction efficiency it is desirable to use a top-down methodology. This means that the whole system is partitioned into a hierarchy of subsystems.

This report describes the procedure in which we accomplished our task, which was to implement a present algorithm. This was made using C++. The algorithm is developed by Sasan Gooran, who is our examiner in this project. The algorithm uses an iterative method to produce the halftoned images. The reason for this project is to speed up the existing program which is made in Matlab.

The environmental requirements and laws on combustion engine emissions are very tough today andthey will become even more stringent in the future. To achieve these requirements there are highdemands on the control systems for these engines. An improved precision in the measurement of anengine's speed and position gives the electronic control system an even better timing when it comes tofuel injection and ignition. This makes the engine more fuel efficient, reducing the emissions. This thesisis part of a collaborative project between Hoerbiger Control Systems and subsidiaries.

This master thesis covers the development of an automatic tuning process for the existing speed controller for drive systems. The drive systems are resonant two-mass systems where a motor is used to drive a load connected by a shaft. The developed method relies heavily on system identification and the construction of a complete mechanical model of the process. With this approach, the common problem with poor load speed control that derives from measuring only the motor speed can be addressed and solved for a majority of such processes.The automatic tuning method has along with general test functions been implemented in a complete tool for automatic tuning, testing and performance evaluation and reporting for drive systems..

Sudoku is a popular game of logic in the form of a puzzle. Sudoku puzzles are printed daily in Swedish newspapers. The challenge of solving these puzzles have inspired many programmers to develop Sudokusolving algorithms. These algorithms use different approaches in order to quickly and efficiently solve the puzzles. One such approach is the use of logical strategies initially developed for human players.

This paper thoroughly investigates needs and requirements for overhead distribution feeder inspection and develops models to investigate possible relations between short term inspections remarks and outages. The study was conducted in collaboration with Fortum Distribution AB that supplied extensive information about their overhead power feeders concerning both inspection and power outages. The investigated models where lognormal linear model, Poisson generalized linear model and negative binomial generalized linear model. All models were implemented utilizing offset terms to compensate for differences in feeder length and amount of overhead versus underground feeders. The Poisson generalized linear model was rejected at an early stage due to overdispersion and neither of the remaining models fit the data perfectly.

This paper presents techniques for speeding up commonly used algorithms forbounding volume (BV) computation, such as the AABB, sphere and k-DOP. Byexploiting the possibilities of parallelismin modern processors, the result exceedsthe expected theoretical result. The methods focus on data-level-parallelism(DLP) using Intel?s SSE instructions, for operations on 4 parallel independentsingle precision floating point values, with a theoretical speed-up factor of 4 ondata throughput. Still, a speed-up between 7?9 are shown in the computation ofAABBs and k-DOPs.

Title:?Speed cameras - an prevention of crime and a standard forming instrument of control??Authors: Markus HanssonTutors: Bo Isenberg & Carl HultExaminator: Ulf DruggeThe School of Human SciencesUniversity of KalmarThe studys purpose is to get a absorbed understanding for peoples attitude, and effect of speed cameras. The disposition for the study is to integrate earlier studies in the matter, combined with elevating interesting sociological conceptions. As an attempt to understand speed cameras as an instrument of force on the individual have Michel Foucaults concept Panopticon been used to see its effect, and it?s look upon how crime prevention will be formulated, which can give an explanation of why speed cameras are being used as an instrument of control on the traffic area.

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..

The aim of this Master of Science Thesis is to develop guidelines and improvementsuggestions of RiNOVA Traffic AB?s dynamic speed bump. The project started with athorough pre study of the design and its function to find out how passing vehiclesaffects the dynamic speed bump. The majority part of the pre study was to createnecessary mathematical models to explain the arisen forces and strains.The results of the mathematical models gave necessary information about the designregarding weaknesses and flaws. The most critical ones where those which interferedwith the design?s performance and reliability, and therefore needed to be corrected.These problems where more thorough analysed and discussed with experts before thefinal guidelines and improvement suggestions where developed.The parts of the design that had to be redesigned were the extension springs and thebearing that enables the dynamic properties.

Handling, loading, transport time and unloading in connection to transport of farm animals affect animal welfare. Induced effects include both psychological and physiological stress responses in animals. The physiological parameters may be measured through blood analysis while behavioural changes often manifest themselves through increased vocalisation, escape attempts and apathy. Physiological parameters are additional parameters of importance when measuring animal stress responses. The handlers behavior during transport has been shown to have major impact on animal welfare and the quality of meat. Animal friendly handling and driving of animals create a more manageable work environment for the handlers. To further increase animal welfare in connection to transport, stables should be built with well adapted drift passage and ramps on the transport vehicle.

The project is a thesis which intends to strengthen the form language and increase the user friendliness of an International Moth. This is a single handed dinghy with only one sail. It sails on two hydrofoils and receives a very high speed compared to its size, and are therefore often referred to as ?the Formula One on water ?. The result is a new concept where the aerodynamic forces have been used to stabilize the boat and relieve the hydrofoils.

Road safety is the result of measures to reduce therisk of accident and injury. (Nationalencyklopedin,2008). In principle, road safety means to arrive saveand sound.Safe traffic in cities is mainly achieved throughappropriate speed. In Sweden, more than half ofall rides happen with a speed above the legal speedlimit (Holmberg, Hydén m.fl, 1996). To reducespeed in order to increase safety requires measureswhich influence a driver?s motives for his orher choice of speed even if these are not rational(Boverket, 2002).
