This Master's Thesis describes the design of a new system where a digital signal processor has been added to an existing imaging system consisting of field programmable gate arrays. The new system will offer a higher degree of flexibility by considerably shortening the design time and make it possible to implement more complex algorithms than the existing ones. The choice of system architecture and a test implementation are discussed. The test implementation consists of a program for the digital signal processor and VHDL code for one of the field programmable gate arrays. The code for the digital signal processor was designed for testing on an evaluation board from Texas Instruments.

A method for equine intra oral radiology has been tested. In the study, both a digital system with an intraoral sensor connected to a laptop and a system utilizing image plates and digital developing was tested, initially on cadaver sculls and finally on sedated horses. The digital sensor was not considered viable for this purpose, while the system with image plates and digital developing worked very well. Two different techniques, i.e. parallel and bisectris, are suggested for the best visualization of different parts of the teeth. Intra carious injections of Mixobar oesophaghus contrast fluid was found useful when evaluating the extent of carious lesions. Compared to extra oral radiology, the new method had several advantages and can be used both in clinic and field practices..

This report is a bachelor thesis presented at the department of Computer Science andEngineering at Chalmers University of Technology. The aim for the project is to find a simplemethod to measure and display physical quantities in a three dimensional room.The report describes a method to construct a system for measuring differentphysical quantities via sensors. The system must be built in a modular and expandable way tobe adaptable to different tasks.The system explained in the report consists of two parts;A physical scanner with moveable probes for carrying sensors and a microcontroller forcontrolling the probes and communicating with the next part.An application written in Java for storing the measured values and presenting them in a lucidperspective.It is possible to construct the scanner with different designs and circuitry, with multiplexers andflip-flops, to ensure that an unspecified number of probes can be added to the system and thatthey can be operated simultaneously.The Java application is written in a modular way, using a design pattern that separates eachindividual part of the application. It contains exceptions and interfaces that ensure a safe andexpandable application..

The avowed aim in this project was to see how the Swedish egg production is today. My first question was if the Swedish egg producers egg production turn a profit. I have done five after calculation at five different egg producers with different systems from case to case. The difference has been the living system, the fodder and the egg price. They made a report in Uppsala, Sweden (Hoffman & Andersson, 1996), where the look forward to a Swedish cage ban and made calculations after that coming ban. After that they lift the Swedish ban of cages and the egg producers could invest in new cages who called the decorated cage.

Dagens teknologiska samhälle ställer höga krav på människan, bland annat gällande att processa information. Vid utformning av system tas det numera vanligtvis hänsyn till människa-datorinteraktionen (MDI) för att erhålla en så hög användbarhet som möjligt. Affektiv Informatik, som är ett utvecklat sätt att förhålla sig till MDI, talar för att utveckla system som både kan uppfatta och förmedla emotioner till användaren. Fokus i rapporten är hur ett system kan förmedla emotioner, via dess färgsättning, och därmed påverka användarens emotionella tillstånd. En kvantitativ undersökning har utförts för att ta reda på hur färger kan användas i ett system för att förmedla känslouttryck till användare.

In this final thesis two simulation models have been integrated. The simulation models are models of JAS 39 Gripen?s fuel system, software and hardware. The time consuming and costly work to develop software has made the department of fuel system to build two models in Xmath/Systembuild. The software model also simplifies the comprehension of how the software in the control computer of the fuel system works.

Permaculture is a design system that aims at developing sustainable human settlements and self-maintained agriculture; it may also be used for community planning. The design system of permaculture aims at mimicking a natural ecosystem; this gives the advantage to make use of all the connections and mechanisms that exist in such a system.The purpose of this bachelor thesis was to compile and spread scientific information regarding five different themes within the areas of ecology, environmental science and permaculture. This was achieved through cooperation with the permaculture inspired Ecovillage Suberbyn in southern Gotland. Information about the central parts of a permaculture ecovillage was used as material for a series of signposts that will be located around the ecovillage Suderbyn. The five selected themes were: An overview of permaculture, The forest garden, The pond, Composting and The use of human excrement and urine..

The Work has been performed to, and in cooperation with Vetlanda Energi och teknik AB.District heating for commercial purpose started in the USA in 1877. Today the network has grown into big and complex systems, which demand maintenance and service to keep up the security of the delivery. When a district heating network expand, it becomes difficult to perform reliable calculations. For this purposes there are a few suppliers who design and deliver systems for documentation and calculation of district heating networks.Vetlanda Energi och Teknik AB is in the position where they must get a system for documentation and calculation for district heating, and therefore they need a basis to get a system. The target is to write a requirement specification that will follow the basis.The Swedish market has been inventoried, and suitable systems have been selected.

Innehållshanteringssystem används för att hantera innehåll och det finns många system att välja på. Detta arbete har fokuserat på fyra innehållshanteringssystem för innehåll på webben. Det är systemen Drupal, Joomla, Polopoly och Wordpress. Syftet var att inhämta teoretisk och praktisk kunskap om dessa system och besvara huvudfrågeställningarna om vilka inbyggda funktioner som finns, hur anpassbara systemen är, hur de olika systemen är att arbeta med för en utvecklare och hur anpassade systemen är för webbplatser med mycket trafik.Det jag kom fram till var att Drupal är ett mycket väl utbyggt och omfattande och anpassbart system där det går att utnyttja mycket tredjepartstillägg och anpassa den efter egna önskemål. Joomla är ett system som innehåller mycket inbyggd funktionalitet och det finns mycket tredjepartstillägg att tillgå, men anpassbarheten är dålig.

Benthic diatoms are used in Sweden for monitoring water quality in run-ning water; the method is also frequently used in other countries in Europe. One of the problems of the diatom method is the need for sedimentation of the fresh sample, to be able to decant the over standing water and add alco-hol as a preservations solution. To my knowledge, no results have been published about how long the settling time must be to ensure that the ben-thic diatoms really have settled down to avoid a loss of the diatoms when decanting the over standing water. The aim of my investigation was to improve the Swedish method where the benthic diatoms are used for water quality monitoring. I wanted to find out the appropriate time necessary to wait until all diatoms have settled down before decanting the over standing water. First, fresh benthic diatom samples were taken in the river Fyrisån and the lake Mälaren on different days. After arriving in the laboratory, I waited three different times (30 min, 60 and 180 min) for the diatoms to settle.

In scientific investigations on how organizations can learn from their mistakes the perspective is usually that of the social engineer; the object is to prevent human errors through modeling the system in a certain way. The aim of this paper is to explore the learning process from a different standpoint than those usually applied in organizational learning and error theory. By studying the learning process in Swedish health care I seek to discover how theoretical presumptions affect the outcome in terms of what we actually learn. The theoretical framework draws on two major discussions in contemporary political science; the question of structure and agency and the question of whether to focus on formal or informal structures when explaining organizational behavior.The investigation shows that Swedish health care tend to understand human errors as a result of formal organizational structure. Such a view leads to insufficient explanations to why errors occur but is useful in producing preventative measures.

Organisations constantly live under the potential threat of events and accidents that seriously could harm the organisation. Forsmarks Kraftgrupp AB, the company that this master thesis focus on, is in no aspect excepted from this threat. Through an early identification of near misses and the taking of corrective action in use, Forsmarks Kraftgrupp AB has managed to reduce the likelihood and the consequence of events and accidents. The purpose of this master thesis is to evalutate Forsmarks Kraftgrupp AB?s operation experience process on the basis of IAEA?s and WANO?s requirements within the field of operation experience and to develop a usable system applicably within the field of operation experience.The thesis is divided into two parallel tracks, where one is the evaluation of the operation experience process and the other the design of a usable system, applicably within the field of operation experience.

According to the Employment Protection Act, the permanent employment is the main condition of employment in Sweden. Nevertheless, nowadays a large number of employers choose to apply other conditions of employment than the permanent employment in their businesses. The rapid technical development and the demands for shorter perspective investment in companies on the Swedish labour market have started the requirement for a more flexible workforce. On-call employment is one of the conditions of employment that is increasing the most. This condition of employment is adjusted by the parties on the labour market.

Internationally most Internet trade related payments are performed with the use of a credit card based payment system on the Internet. Payment against invoice is still most common when trading over the Internet in Sweden. The security development, comfort and timesaving indicate that credit card based payment systems on the Internet soon will have a breakthrough in Sweden as well. The Swedish legislation concerning payment is neither especially extensive nor suited to electronic payments but to payments performed with notes and coins. When the legal effects, of a payment performed with a credit card based payment system on the Internet, set in is not fixed.

The Swedish working-class author Ivar Lo-Johansson (1901-1990) wrote a collection of one hundred short stories between the years 1968-1972. His other productions, generally speaking, have partially different social reform purposes, but, according to himself, these short stories were written with the intention to be totally free of tendencies (even though he himself doubted that he succeeded with this).During the same period that these short stories were published, the Swedish social democrats were under the challenge of radical movements that, mainly on the radical left?s ideological foundation, had a relatively strong influence in Sweden, among other countries, from the mid 1960?s to the late 1970?s. Since Lo-Johansson mainly seemed to have supported the politics of the social democrats, the purpose of the investigation in this thesis has been to see if he ? in the three short stories: Vikingakärlek (1970), Rikslögnaren (1971) and Ansgars resa till Sverige (1972) ? is conveying an ideological use of history and basic political values that were used by the social democratic party during this time period.
