Problem: Our opinion is that it is important to consider about usability in system development. In this thesis we will focus on usability in point-of-sale systems. The point-of-sale system we base this thesis on is Extenda Retail. Our case study is performed on Ica Kvantum in Bromölla, which implemented Extenda Retail about two years ago. Purpose: The purpose of this thesis is to figure out what important factors there are to consider, in usability aspects, when developing point-of-sale systems, with focus on the cashier. We also wish to find out the cashiers opinions about the Extenda Retail system. Method: The information gathered for this thesis consists of literature and interviews.

Kitron had wishes to be able to test and measure how disturbance affects their vehicle electronic units before they have been verified by SP Technical Research Institute of Sweden in Borås. This work started with the writing of a demand specification together with Kitron for a product PSQS, Power Supply Quality Simulator, which can generate some test pulses according to a standard for electronic units to Volvos vehicles. A design proposal was developed with the help the demand specification and was verified with the help of simulations. All electric schematics was designed with the guide of the design proposal. The pulses realized in the works of this thesis are those which Kitron experienced that they have a need to test in their own premises and which are possible to generate with the means available.

The objective of this study was to make an inventory and a potential analysis of the organic beef production in the region of Gävleborg, Sweden. A survey was conducted, where a questionaire was sent to all farmers in the region who had environmental subsidies concerning organic cropping systems in 2001. In total, there were 701 farmers, of which 46 % participated in the study. Three slaughter houses were interviewed to get their pictures of the development of organic beef production. The study shows that there are potentials and interests in the region to increase the production of organic beef.

I den här rapporten undersöks med utgångspunkt från empiriska data om momentumstrategier har genererat en överavkastning på Stockholmbörsens Large Cap-lista mellan februari 2000 och februari 2010. Vi undersöker även för vilka tidshorisonter som effekten är starkast, samt vilken påverkan transaktionskostnader och riskjustering har på överavkastningen. Resultatet visar på en statistiskt säkerställd överavkastning för sex (6) av de totalt sexton (16) momentumstrategier som ingått i studien. Dessutom visade alla övriga momentumstrategier en icke statistiskt säkerställd överavkastning. Effekten ter sig starkast för urvalsperioder samt investeringsperioder på 3-6 månader, vilket är inom det intervall på 3-12 månader som Jagadeesh och Titman (1993) fann i sin studie.

Technical products are becoming more and more complex, this means that the drivers, mechanics and service personnel?s need for assistance such as the service literature is increasing. In this degree project the focus is on the technical manuals of Scania?s Workshop Manual. Today, the information in the Workshop Manual consists of collaboration between text and illustrations.

Sweden has long had access to low electricity prices due to the wide availability of hydro and nuclear power. This has now changed because of today's rising electricity rates resulting in increasing heating costs for properties, especially in the properties with electric heating systems."Ankaret" is a parish for "Svenska Alliansmissionen", which is located at "Gullbrannagården".The parish has installed electrical radiators and an exhaust ventilation system that makes the energy demand high due to the large ventilation flows. The building was built as the price of electricity was still low and would reduce energy use today by combining its heating system with an air/air heat pump. The heat pump delivers more heat into the room than the electrical energy that it uses. This lowers the electricity needs.

A large number of genocides have taken place in our history. The purpose of this essay is to examine how genocide is treated in five high school history textbooks. I have studied a large number of issues. I have examined which genocides are discussed in the textbooks and which genocides the textbooks don?t discuss.

The purpose of this study is to facilitate sustainable building by the use of BIM. The goal is to determine which aspects of sustainable building, which can be analyzed mainly with BIM tools, but also other aids.The study is based on literature studies and interviews. The literature review examines aspects important for sustainable building by studying environmental certification systems applicable in Sweden, as well as the BIM tools available on the market to analyze these aspects. The literature also includes the concepts of BIM and sustainability in order to provide a clearer view of its meaning. The interviews have brought the study's overall understanding of the industry and guidance on the subject.The results are presented in a table, where the aspects relevant to sustainable building are listed.

Göteborg Energi has a surplus of district heating during spring, summer and fall. The heat surplus is due to a constant production of waste heat from oil refineries and heat from waste incineration over the year. It would be desirable to increase the demand for heat and the uptime for the newly built combined heat and power generation plant, Rya Kraftvärmeverk. One alternative could be to integrate Rya Kraftvärmeverk with a pellet production facility. By producing heat, electricity and pellet in a joint process the energy use can be decreased.

AbstractMy purpose of this essay was to discover three- and four-year-olds comprehension of their internal body and then compare the result between their ages. I have used the same methods in both essays, semi-qualitative interviews. It is structured interviews with space for following questions. My formulations of the questions were: Do the children have a comprehension of their internal structure of the body? Do the children have a comprehension of organs and organ systems? Is there any difference between the ages?Their comprehensions I have categorized in four categories and I have seen age related differences in their comprehensions.

This thesis presents a comparative study of image registration at two picture collection libraries. The two registration systems are analyzed as to the theoretical principles behind them and their practical application, and related to theoretical tools for subject analysis and bibliographic standards. While a growing number of picture collections now digitize their material, generally accepted standards and methods for the registration of digital images are still lacking. Many different systems coexist, often developed in-house in response to ad hoc needs and based on traditional registration tools created for textual documents, resulting in internationally incompatible mixed-format systems. The two picture collections examined here, however, have opted for similar, standardized tools for registration and subject analysis, and while there are differences in their application and focus, they have both considered issues of cross-system compatibility.

This study was performed to examine the performance of an equity based crowdfunding campaign, as well as seeking to describe the risks, complications and the opportunities that this kind of funding brings. The study was conducted by an empirical case study of a company that was about to initiate an equity based crowdfunding campaign.The conclusion is that the planning of an equity based crowdfunding campaign is time consuming and requires knowledge in many different areas. Therefore it is important to identify in which areas skills and resources already are available within the company, and where it must be obtained through a learning process.The report also highlights that equity based crowdfunding, because of legal restrictions surrounding the issue of unlisted shares, can not be marketed as other types of crowdfunding. This leads to the conclusion that those who invest in equity based crowdfunding do not necessarily belong to the crowd that crowdfunding is generally associated with. Arguments can be made that this crowdfunding model rather resemble traditional angel networks.A technical study was also made about the company's products.

As the information society becomes increasingly flooded with digital images, the need for efficient image retrieval systems increases as well. To handle the vast amounts of data involved, the indexing process needs to be run automatically, using content-based descriptors extracted directly from the digital image, such as colour composition, shape and texture features. These content-based image retrieval systems are often slow and cumbersome, and can appear confusing to an ordinary user who does not understand the underlying mechanisms. One step towards more efficient and user-friendly retrieval systems might be to adjust the weight placed on various descriptors depending on which image category is being searched for. The results of this thesis show that certain categories of digital images would benefit from having extra weight assigned to colour, texture or shape features when searching for images of that category..

In this paper I will present my research about different kinds of social workers, and there way of looking at and working with adolescents alcohol use. To get my result, we interviewed eight social workers from four different organizations. The Interview participants were people working with adolescents on their spare time, and in the school environment. There were also participants representing social services and the police. The theory that we have chosen to apply to our thesis is systems theory.
