An information system is something that evolves over time to enhance the company that is using it. The technology for building an information system is also evolving. New methods and new programming languages make system development easier. As new technology breaks ground and the demands of a company?s information system grow, the company will sooner or later get to a point where a change in the base of the system is necessary.

Abstrakt -  As energy prices rise, energy-saving in buildings is becoming increasingly important. By applying different construction and installation technologies, to new buildings the energy consumption can be reduced effectively, compared to similar existing buildings. These technical measures are often an investment in the long term and will reduce energy costs significantly. The purpose of this report is to show how to reduce energy consumption in a small house. It is presented in this report that both building's technical saving arrangements (the sealing of a building) and an installation technical arrangement (changing from the F-system to the FTX-system) would reduce energy consumption in newly built detached houses, if compared with a similar existing house but without these technical measures. The report presents also detailed calculations showing how much energy an existing 2-storey house, built in the year 2007 in Eskilstuna, consumes and how much energy would be saved if these corrective measures were applied to a new building. It is also reported how much money would be saved each year over a 10 year period if the measures were applied. The results show that both solutions are a good investment in the reduction of energy consumption and hence the cost involved. Keywords: energy, heat energy, infiltration, FTX-system, free temperature effectively. .

In this thesis a number of energy saving methods for a multiplier on algorithmic level are investigated. For the investigation a multiplier is constructed in VHDL, after which the circuit's performance is investigated. A number of techniques for reduced power consumption are introduced in the circuit and are then evaluated. The conclusions are that all investigated methods, pipelining, interleaving and voltage scaling, should be maximally made use of in order to minimize the power consumption..

Linux is a growing operating system in embedded systems. Today, Linux is not only in heavy servers but also in cell phones, PDAs, cameras and other devices running on battery power. While current technology is more energy efficient, more and more technologies are implemented into a single unit resulting in an overall increase of power consumption.Low power consumption is an increasingly important feature of a system today. Lower power consumption means lower costs, less environmental impact, and longer life for applications that runs on batteries.This work compiles methods to reduce power consumption of Linux systems. The work includes examining whether the available opportunities are platform-specific or of a more general nature.

The release of green house gases and the environmental impacts humans have on the environment are huge and might cause irreversible changes to our earth. Meat is considered to have large impacts on the environment, especially beef meat and therefore there have lately been considerable discussions on the sustainable level of meat consumption and production. The main goal with this thesis is to study sustainable meat production and meat consumption in the county of Dalarna in Sweden. Indicators for sustainable meat production and meat consumption were developed and applied on three cases. Interviews were carried out with a municipality in the region that represents the consumer and three beef farmers that represents the producers.

The aim of this study was to investigate the knowledge of dental erosion and the consumption habits of soft drinks among secondary school students. Differences between the sexes should also be investigated. The study consisted of 102 students, 60 women and 42 men, in the eleventh grade from a school in the south of Sweden. A questionnaire with 25 questions, divided in two parts with focus on knowledge respective consumption pattern and behaviour, was handed out and collected by the authors. The data showed that more than 50% of the participants had knowledge about dental erosion.

The free choice of upper secondary school?A study of the meaning of the information channels for the choice of upper secondary schoolAuthors: David Fridner & Rikard ZeilonMentor: Ingela WadbringQuestionnaire studyDate: 2008-08-11AbstractThe choice of upper secondary school is a very important choice, both for the school and for the ninth grader. In Göteborg, the free choice of upper secondary school has generated several new information channels apart from the traditional counselor, daily news and the acquaintance. Today it is harder than ever to reach the pupil through the constant media noise and new forms of communication such as events appear. The fight for each pupil gets more and more important every term and it has now become real big business.Today?s youth is imprinted by a growing individuality and everyone knows that equableness is something very important.

This research study constitutes a critical stand, which departure from the increase in welfare, and decrease in quality of life, and is further directed to the sphere of consumption. Contemporary consumers appear to seek for components to construct their self with through consumption, consumerism has become a sphere of life, and has consequently also become a victimizing force steering the identity and self construction of consumers. The alarm bells however are echoing in Western society, and consumers are experiencing dilemmas such as fragmentation, powerlessness, uncertainty and meaninglessness.In this respect we have presented spiritualism as an applicable path of escape or alternative to the scheme of the material oriented consumption sphere. We intend to broaden the scope of the interplay between spiritualism and consumerism in the act of yoga, and we have therefore been researching: what yoga is doing to consumers, and what consumers are doing to yoga. The study is based on an existential epistemology paradigm, which emphasis on the meaning of the yoga experience attained from the subjects of research; the yoga practitioners, and therefore we have carried out three focus group discussions.

The hospital in Varberg has a somewhat outmoded solution regarding the state of preparedness in its water sustentation. Today?s solution is both cause to a number of mishaps and high energy consumption.The report is initiated by looking into the present situation to get an insight to the problem.Today?s media depletion is measured and analyzed.Furthermore, it also looks into some earlier performed studies. These studies are followed up in order to see if measures have been taken.The report presents a number of arrangements which should be taken, amongst those a minor re-build of the current solution and a number of arrangements which leads to decreased water consumption..

Citizens? freedom of choice has been a subject of debate in Sweden for over 30 years. This study focuses on decision making processes among patients within the Swedish healthcare system. The main conclusions are that in contrast to how patients? freedom of choice is described within governmental bills and governmental inquires and reports, patients are not following the steps included in the rational model of decision making.

One of the main goals in this study is to investigate how young children's identity formation and social relationships are depicted by today's consumer society.  In order to reach the goals of the study I also concentrated myself on questions regarding the reflection of symbolic aspects consumption in younger children's interaction and preschool-teachers' ideas about how and in what ways children's consumption patterns are created and developed nowadays. In order to answer the presented research questions I used the theoretical arguments of researchers in the field of pedagogy Gert Biesta in connection with the ideas and concepts of the consumer society characteristics developed by the sociologist Zygmunt Bauman.The thesis' methodological approach consists of a combination of semi-structured interviews with teachers and observations of children's interaction, which contributed to a systematic investigation of the thesis' problem area and served as a tool for obtaining answers to the research questions.The results demonstrate that consumption occupies a lot of space in young children's lives, which means that it greatly affects their social relationships today. Both consumption and knowledge of the known brands prove to be the child's path to the desired community on the one hand, and the children's way to the consumer world on the other (hand), which in turn points to an obvious dependence between children's consumption and their social relationships.The results also show that there is a tension between the perception of identity formation as preschool-policy-document on the one hand and the attitude of the identity prescribed by consumer society norms and regulations on the other..

?CSR and political consumption ? a study of Nike?s and Puma?s CSR-reports?The purpose of this dissertation is to examine if political consumption has influenced multinational corporations to improve their Corporate Social Responsibility reports and policies more, than a company who has not been a target for political consumption.This dissertation is a content analysis of Nike?s and Puma?s first (Nike 2001, Puma 2001) and latest (Nike 2007/09, Puma 2007/08) CSR- reports. Archie Carroll?s model of Corporate Social Responsibility is used as theoretical framework in this study. The model is used to focus on four areas within CSR; economic, legal, ethical and philanthropic.

Simulation of different systems can be done using a graphical model description of the system based on block diagrams. The simulation software Matlab/Simulink offers a lot of possibilities to describe a huge number of systems, which can be linear as well as nonlinear. The simulation using Matlab/Simulink is done by integration based on different kinds of numerical methods.When nonlinear Simulink-models are simulated, it is often interesting to apply a Kalman filter to handle the noise that may occur within the process as well as corrupting the measurement. However, application of such a filter leads to an extensive time-consumption despite using fast computers. The reason is that the existing Matlab functions are not constructed for time optimal evaluation.

 IAS 40 allows two methods of valuation for investment properties, fair value model and cost model. The purpose of this paper is to investigate what drive property companies to disclose their investment properties at fair value. In order to understand their choice, we use accounting choice theory and the three factors this theory describes, information asymmetry, allowing opportunism and agency costs. To answer our purpose, we have from a qualitative approach performed semi-structured interviews with respondents from five of the largest listed property companies in Sweden. The results suggest that firms have chosen the method that is most effective in the valuation of investment properties.

The essay aimed to investigate whether people choose light products or original products regarding dairy products and beverages as well as the motives for their respective choice. Finally the purpose was to find out where they had obtained the knowledge to make their choice and how they thought media had affected their choice. The method used was a qualitative decsriptive study with three focus groups consisting of six women aged 40-50, six women aged 20-30 and four men aged 25-35. Each interview lasted 2 hours. The groups were a selection of comfort.   The results showed that all respondents choose original products. The primary reason was because they thought that original products tasted better and had a better consistence.
