This thesis has been performed at the system development company Verendus System AB, together with the home care company Basic Care Unit (BCU).The thesis has consisted of developing a web based informationsystem for BCU in which they can administrate their business. At the time of writing this thesis, BCU was using a windows-application to administrate their activities, which was both costly aswell as resulting in an unnecessary burden. The aim the thesis has thus been to create a platform-independent information system that simplifies and streamlines BCUs work by being user-friendly aswell as imposing some simplifying features.The students has been developing the system by the help of a work method they themselves developed. The method consisted of working in several iterations that each had several milestones. The method resulted in the students knowing easily when each iteration was finished or not.The thesis resulted in a working platform independent prototype.

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 samhÀlle stÀller höga krav pÄ mÀnniskan, bland annat gÀllande att processa information. Vid utformning av system tas det numera vanligtvis hÀnsyn till mÀnniska-datorinteraktionen (MDI) för att erhÄlla en sÄ hög anvÀndbarhet som möjligt. Affektiv Informatik, som Àr ett utvecklat sÀtt att förhÄlla sig till MDI, talar för att utveckla system som bÄde kan uppfatta och förmedla emotioner till anvÀndaren. Fokus i rapporten Àr hur ett system kan förmedla emotioner, via dess fÀrgsÀttning, och dÀrmed pÄverka anvÀndarens emotionella tillstÄnd. En kvantitativ undersökning har utförts för att ta reda pÄ hur fÀrger kan anvÀndas i ett system för att förmedla kÀnslouttryck till anvÀndare.

En undersökning av hur gymnasielÀrare i fysik anvÀnder metoder som inkluderar informations- och kommunikationsteknik i sin fysikundervisning gjordes. Studien baserades pÄ intervjuer samt enkÀtsvar av sex lÀrare frÄn olika gymnasieskolor inom VÀsternorrlands lÀn. Intervjuerna analyserades i en jakt pÄ övergripande mönster och enkÀtsvaren sammanstÀlldes för att ge kompletterande kvantitativt stöd till intervjuerna. Slutsatserna visar att ingen av de hÀr lÀrarna arbetar med metoden RealTime Physics, men att de till stor grad anvÀnder liknande metoder pÄ liknande sÀtt men Àven att det ?nns en spridning inom gruppen nÀr det gÀller hur de anvÀnder den hÀr metodtypen.Undersökningen visar Àven att den hÀr lÀrargruppen har en positiv syn pÄ den hÀr typen av metoder Àven om de identi?erat behov av mer teknisk utrustning, kompetens och tid för att arbeta pÄ det hÀr sÀttet..

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.

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.

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.
