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.

This work aims to evaluate the possibility of using a graphical programming language to develop software for a digital signal processor. A fixed-point digital signal processor called Blackfin BF-537 is used for this. Instead of using conventional programming languages, like C or assembler, for software development the possibilities to use a graphical environment to fill the same purpose are examined. The development environment primarily used is NI LabVIEW, but also the use of Mathworks Matlab Simulink is investigated. A variety of programs consisting of various signal processing operations and utilities are developed using these development environments.

The Rya power plant in Borås produces district heating, district cooling and electricity. The plant is owned by Borås Energi och Miljö AB and is run by Dalkia Facility Management AB.In order to get the best heat exchange from the district hot water a pair of twin pumps and a turbine circuit pump are used as return pumps. Turbine circuit pumps are used to increase the pressure through the heat exchangers at the power plant. The pumps are in use when the flow is over 2 000 m3 h-1 and during the summer when re-cooling is used to improve the effectivens of the heat boilers.Since the pumps, that are parallel connected, rotating at a fixed rate per minute, the pressure is regulated with regulating valves. This report shows that during the 4,300 hours that the pumps where in use, energy corresponding to 590 MWh was wasted.

I denna studie undersöks hur införandet av jobbskatteavdraget 2007 och de två utbyggnaderna 2008-2009 påverkade arbetsmarknaden i form av sysselsättning, arbetslöshet, långtidsarbetslöshet och sysselsättning i åldersgruppen 55-64 år. Med utgångspunkt från en tillämpning av konsumtionsteorin, med arbetsutbudet i fokus, så görs en difference-in-differences analys av reformens tre första år i jämförelse med tre år innan dess införande. Resultaten visar att införandet av jobbskatteavdraget har haft en positiv effekt på arbetsmarknaden i form av en större andel avbefolkningen i arbete, medan ytterliggare steg av jobbskatteavdraget ger estimat som tyder på att effekten blir en minskad aktivitet på arbetsmarknaden..

This report provides a comparison between the products cellular concrete, foam concrete and LECA concrete. The questions to be answered during the work is how the cellular concrete stands up in cost terms to the existing competitors on the market, how the concrete products differ in design work, and in which situations the concrete varieties are preferred to use.Cellular concrete is a variant of ordinary concrete, with the difference that the ballast is exchanged from stone materials to expanded polystyrene beads (EPS). This substitution gives a product with higher insulation values but lower weight than ordinary concrete.The work was carried out by designing a survey which was sent to two hundred randomly chosen companies across Sweden, to see the building industry?s opinion of the product cellular concrete. The survey showed that cellular concrete was equals its competitors in terms of price, while the product was said to be more flexible, quicker and easier to cast.Then some of the companies, who participated in the survey, were interviewed to see more carefully, how the price, the workmanship and the time for casting and dehydration differed between the products.

Under senare hälften av 1990-talet har narkotikamissbruket i Sverige ökat. I denna uppsats undersöks huruvida detta har påverkat den övriga brottsligheten genom en analys av data frånen panel bestående av samtliga svenska län 1995 ? 2004. En Fixed-Effects- modell som kontrollerar för läns- och tidsspecifika effekter har anpassats till datamaterialet. Måttet på narkotikakonsumtion är baserat på den årliga enkätstudie som genomförs bland 18- åriga män som mönstrar till värnpliktstjänst i Sverige.

To be a part of the future we have to make a profit, one way to improve the profit margin is by reducing the fixed costs. This paper discusses the financial results of equipment cooperatives in crop production. Through a case study of three farms in Södermanland, we have an example of how it can look today and how it could look tomorrow. The three farms are crop-producing farms with slightly different orientation. Jursta Gård, 155 hectares, and Djursnäs Säteri, 215 hectares, have grains crop and oilseed crops as the main crops, and Nibble Gård, 340 hectares, mostly have pasturelands and some grain crops.

In this report a study is carried out with the aim to identify added values of EPC projects implemented in schools in order to increase the interest of EPC projects on the market. The report examines how the planned maintenance, supervision, maintenance and corrective maintenance is affected, how insurance premiums and terms are affected, the indoor environment and how the tasks of the operating staff is changing. A literature study of energy savings, energy use in schools, maintenance and insurance as well as how energy efficiency improvements are related to the Swedish environmental objectives has been made. Visits were carried out in Ludvika, interviews were also carried out with operation technicians and local strategists in Ludvika as well as employees of insurance companies.Schools often have neglected maintenance and problems with ventilation and indoor environment. Schools also have a large energy saving potential due to their low utilization, mainly because they are empty parts of the year.

This essay is an attempt in analysing the establishment of the first Early Middle Ages castles in Scania. There are two types of castles in Scania during the eleventh century, keeps andringworks. This castle was built by three fixed elements of power: the crown, the church and the aristocracy. The result of the survey shows that A majority of the castles during theeleventh century in Scania where initiated by the church.The results also show two building phases of castles under the period. The first building phase begins in middle of the eleventh century and the second building phase begins in theperiod 1180- 1200.

This degree project concludes the Innovation and Design Engineering programme at Karlstad University. The project was carried out by David Brocker, Erik Hallberg and Andreas Hertzman during the spring of 2006 and corresponded to 15 weeks of work per student. Assigner was Martin Larsson at Arexor and instructor at Karlstad University was Monica Jakobsson.Arexor has a patent to a construction of an electrical skirting board with moveable wall sockets, called Electrical Track System. The lowest parts of the interior walls along the floor are today almost always covered by a conventional skirting board. Arexors patented product replaces that with the possibility to move and increase the number of wall sockets by choice along an electrical skirting board.

The aim of this project was to create an interior design for a children?s hospital patient room with the concept to adapt the room for the wide target group from 0-18 years of age. The analysis in the project is based on the hospital ward 322 at Drottning Silvias Children?s and Youth Hospital in Gothenburg. It?s an oncology ward where the children are very sensitive for infections and therefore need to be isolated in their rooms for 3-4 weeks.The main goal for the project was to create a room that works as a template and gives the people who lives in it the opportunity to create thier own room based on the personal things they bring into it, and how they decide to furnish and use the room.The result of the project is a template room with fixed furniture that can be transformed due to screens in the room.
