The purpose of this degree project was to build laboratory equipment for a new course in power electronics that starts this autumn 2010 at Uppsala University. The equipment is intended for student labs and it covers the most important areas of the course including rectifying, buck-/boost-converters and PWM-modulation. It is built as one sealed unit where all the electronics are built-in but visible and it has a connection board where students safely can connect the different circuits. The project has advanced from theoretical studies of circuit design, choosing of components and simulations to drawing the printed circuit board (PCB), soldering, case building, final testing and troubleshooting - basically most steps from an early idea to a final product. Measurements on the final product gave about the same results as the earlier simulations of the circuits and the result is overall satisfying..

AbstractThe purpose of this investigation is to find out how the pupils can discover and to feel joy in their creative art activity and also to believe in their own ability. The aim is to figure out if creative art activity is able to raise the pupil?s self-image. By literature, pedagogue interviews, and interviews with pupils at the age of ten years old and by action research is the way that I have searched for an answer for my question. The main result is that fantasy, creativity, courage and lust are important parts to develop in the job of raising the self-image.

The product structure of the fuel tank installation is one of the most complex product areas at Scania. Caused by the number of parameters, which affect the fuel tank installation, a product structure is created which is very difficult to handle. Knowledge exist that the structure in a nearby future will be considerable more complex. The purpose of the study has been to understand in why this complexity exist and find ways to break the trend of a growing product structure. The goal was to achieve a more standardized fuel tank installation.A theoretical study was performed in order to bring knowledge in relevant areas both in general theory but also in documentation at Scania.

This master thesis describes the development of an UPS module. UPS is an acronym for Uninterruptable Power Supply. The UPS module has been developed at the company AerotechTelub AB. The UPS module delivers the necessary voltage and current in case of a power interrupt. If a power interrupt occur, the computer system has one to three minutes available to store data and shut down correctly.

When designing roads it?s important to knowwhat loads will bedriven on it. The axles on heavy vehicles can either have super single tires ordual tires which, according to studies, damage the roads differently. The SwedishTransport Administration is developing an understanding for the character ofthese different kinds of axle and tire types on the loads induced on Swedishroads. In this thesis a field study was conducted to determine the distributionbetween axles with super single tires and axles with dual tires on heavy vehicles.A highway, a country road and a national road were investigated during thestudy.

Solid waste management is one of the most essential functions in a country to achieve asustainable development. In India, it has been one of the least prioritized functions during thelast decades. The most common ways to treat waste in India today are open dumping anduncontrolled burning. These methods are causing severe environmental pollution and healthproblems. India is one of the world?s largest emitter of methane gas from waste disposal.Since methane is a strong greenhouse gas, even small emissions have large impact on theclimate.

In 2010, Airwatergreen AB started testing their new technology, the Airwaterwell, an atmospherical water generator of their own design that is running on solar heat, with a production capacity of three litres of water per day and m2. The purpose was to focus on foreign aid organizations as main purchasers for project investments towards rural communities in developing countries that suffer from lack of, or compromised quality of drinking water. In order to further understand if this technology would bring a positive impact in the developing countries, the company contacted the Swedish University of Agriculture for a socio-economic study of the Airwaterwells? potential. The authors elected Cost benefit analysis as the appropriate method for conducting the study and India became the study region because of its many problems with water related issues such as diseases as well as insufficient water supply for households. The regions that this study is based on are Gujarat, Haryana and Uttar Pradesh given their differences in income, health situation and poverty rate.

I en omvärld som ställer allt högre krav på delaktighet kom ett uppdrag 2000-03-30 till Norrbottens Flygflottilj, F 21 som på nio månader skulle sätta upp ett nytt internationellt förband. Om förbandet kallas ut blir det första gången sedan sextiotalet som Sverige fullgör tjänst med krigsflygplan utomlands. Swedish Air Force Rapid Reaction Unit, SWAFRAP AJS 37 skulle ställas i 30 dagars beredskapDenna uppsats syftar till att beskriva och analysera den planeringsprocess som har genomförts på F 21 ur de traditionella perspektiven problemformulering, genomförande och utvärdering avseende detta nya förband.Undersökningen har genomförts som en fallstudie på F 21 och avgränsats till AJS 37. Planeringsprocessen har studerats genom intervjuer av chefer inom SWAFRAP organisationen.Studien pekar på att processer av detta slag är ytterligt komplicerade och kräver mera forskning om vi skall lyckas förstå alla ingående komponenter och deras interaktion..

The aim of this study is to contribute to a better understanding of the syllable as an alternative to the phoneme at the basic reading and writing. This report is based on a qualitative analysis of Håkanstorp school´s approach to the basic reading and writing in class. Their approach to reading and writing is controversial, as it is based on the syllable instead of the phoneme, as usual in the traditional reading and writing. The education result, I have found, is that the syllable leads to a very clear and structured working procedure, which ultimately leads to class teachers being able to work from a diagnostic approach. This structure, with many parts of the course helps educators to clearly follow what level students are at.

Att skriva enhetstester är en viktig del i nya populära systemutvecklingsmetoder som extreme programming. Med testdriven utveckling skriver man testerna innan den källkod som skall testas. Ett vanligt problem med dessa tester är att de blir beroende av delar i systemet som inte är intressant för själva testen. Mock objekt är en teknik som gör det enkelt att isolera tester från allt som inte är relaterat till det som skall testas.Det finns två sätt att se på mock objekt. Den traditionella synen är att mock objekt skall användas som ett verktyg vid isolering av externa system.
