Minimizing power consumption is a critical part of many embedded design projects. Thechallenge is to limit the power consumption of the system and at the same time providesatisfactory service to the user. With regards to microprocessors, the main way of limiting powerconsumption during program execution is to adjust the frequency and the voltage at which theprocessor operates.To enable the implementation of real-time scheduling with support for dynamic voltage andfrequency scaling, an exhaustive study of the Freescale i.MX31 embedded microprocessor isperformed. Specifically, the power consumption relationship to all relevant frequency andvoltage settings is investigated. In addition, to enable frequency and voltage scaling in a real-timeenvironment, a complete timing analysis of proposed voltage and frequency scaling methods isperformed and their suitability for use in real-time systems is evaluated.To integrate voltage and frequency scaling capability into OSE RTOS, a software module hasbeen developed for this operating system.

According to Food and Agriculture Organization newsprint is defined as: Uncoated paper, unsized (or only slightly sized), containing at least 60 percent of mechanical wood pulp. The consumption of newsprint in Sweden was just over 798 000 tonnes in 2009, which represents approximately 90 kg per person. Although there are studies that predict a drastic reduction in newsprint consumption in the Western world, there seems to be a clear difference between forecasts for the future given by statistical analysis of newsprint consumption and forecasts given by experts in the industry. The former predict a continuing increase while the experts see a coming decrease in consumption.In this report, both demand and business strategies of newsprint in Sweden are studied. The study also presents a forecast of the future which is based on historical data and qualitative interviews.

This thesis has been carried out on behalf of IV Produkt AB and intends to set an average ratio of thermal energy losses in apartment buildings that were built during the 1960-1990. This shall be derived by analyzing the total district energy consumption that has been divided into three parts: heat energy losses (the actual heating requirements), the heating of domestic hot water and heating energy consumption for the controlled ventilation.Three different residential areas that were built during the years 1962-1966 and one that was built in 1993 has been analyzed. All residential areas are located in Växjö urban and contains between four and six apartment buildings.The analyzed objects have a mechanical exhaust ventilation systems and district heating as the heating method. No own laboratory work or experiments have been done in this thesis, the calculations have been done on the basis of parameters from VEAB, interviews with property managers, and literature studies. By calculations, we have got a result that is reported in Chapter 6.

This examination intends to find out what thoughts children in around 12 years of age thinks about their own television consumption. To examine this, the questions in issue is: ?What does the children watch on television?? ?Why do they watch the programs they do?? ?How do the children speak about their own consumption?? ?What does the children learn from TV?? ?Are the children concious of the impressions they take from TV?? ?Do they speak critical about TV?? ?Is there anything indicating on some kind of influence from the childrens television consumption?? .To answer these questions I have chose to hold qualitative interviews, to let the children?s own thoughts be the foundation of the examination. The theories in this examine are that the person who does the consumption from different forms of television takes the information personally out of her own reality. Meaning that the person watching is the judge of how she applies the information to herself.

This thesis tries to clarify why more houses such as passive houses is not built and at the same time the differences is described with the conventional construction as a starting point. Sweden has set environmental objectives to reduce energy consumption in buildings by 50 percent by the year 2050 compared to 1995. The passivehouse concept could have a significant role, particularly in the reconstruction of buildings with high energy consumption. For sustainable building the passivehouse technology is an economically viable concept while benefiting the environment. Initially an introduction is given of the background to the problem, purpose and objective of the thesis.

This thesis studies private equity firms' implementation of management control systems in their portfolio companies and whether the systems are affected by cross-national differences. A comparative case study examines five different private equity firms to derive if there are any differences between the private equity firms' management control systems in the United States, Europe and China. The empirical observations are categorized according to the framework developed by Merchant (1985) and further developed by Merchant and Van der Stede (2003). Theory on the effect of multinationality on management control systems, also developed by Merchant and Van der Stede (2003), are used to explain possible findings. The applied theory includes the cultural dimensions developed by Hofstede (1984) and Hofstede and Bond (1988).

The purpose of this study was to investigate to what extent  young adults use media to create the image of themselves. The questions we wanted to answer was as follows: what does the media use of young adults look like compared to their attitudes towards media content; what awareness do they have of other young adults attitudes concerning media content; and finally, how do these attitudes affect their own media use?Media consumption is a great part of  the daily lives of young adults living in Sweden: the national  average media consumption is seven hours a day, for 15-24 year olds. This provides a new way for young adults to express their identity - by showing their use of different media content, they can change other's perception of themselves.The method we used in our study was a combination between a quantitative and a qualitative method. We first made a survey in three classes with senior year high school-students, in a Swedish school.

Syftet med uppsatsen har varit att undersöka om det finns skillnader i chefskapet mellan danska kontra svenska nya första linjens chefer utifrån en nationalkulturell aspekt. Studien har utgått från ett induktiv angreppssätt där vi har valt att använt oss av såväl kvalitativ som kvantitativ metod. Detta i form av 21 semistrukturerade intervjuer riktade till nya första linjen chefer och 108 enkätstudier riktade till deras medarbetare. Studien har genomförts på sex olika företag i Öresundsregionen som bedriver verksamhet i såväl Sverige som Danmark. Det teoretiska perspektivet i uppsatsen har utgått från Geert Hofstede´s teori beträffande nationalkulturer samt de specifika förutsättningarna som föreligger för de båda länderna.

This rapport contains an examination of the energy consumption of a kindergarten, which areas that have the largest impact on the energy consumption and what can be done to reduce those areas in ways that are relatively easy and profitable. It is also analyzed if it is possible to reduce the energy consumption from today?s consumption to a consumption that fulfils the demands placed on low energy houses by FEBY.The focus has been on reducing the energy consumption of the areas ventilation, heating system and hot water system, since those seemed to be the easiest ones to affect and since the building is quite recently built.There are different kinds of ventilation systems, at the moment the building have a CAV-system, which means that the ventilation is too high during large parts of the day. There are different ways to manage the ventilation system, for example presence detection, humidity sensors, CO2 sensors, temperature sensors and season adjustment. Many of those are in the end dependent on CO2 sensors to guarantee a good indoor climate, therefore the focus have been placed on this system.

The Swedish energy companies have several different systems for data collection of the energy consumption of their clients. Often computerized remote meter readers are put in practice in order to register the energy consumption of large companies. The majority of household clients, however, are read off by the assistance of manual methods. Household power consumption is read off once a year. As a result, these clients are not debited for their actual consumption; their invoices during the year are the result of estimations.

Australia is one of the largest producers and consumers of fossil fuels in the world. In a society where the effects of fossil fuels on global warming are constantly discussed, the nation?s production and consumption are subject to debate. Problems arise when negative aspects of consumption, such as emissions of greenhouse gases, are put in relation to an increased need of energy and economic growth. However, it is important to distinguish between different types of fossil fuels when it comes to their individual impact on the environment and to analyze the possibilities to increase the more environmental friendly ones.

The aim with this thesis was to acquire an understanding for how individuals handle the feeling of shame in connection with cultural consumption. In order to capture the feeling of shame we developed an interview method called the Backstabber interview technique. We found that the Backstabber interview technique successfully triggered feelings of shame in connection to cultural consumption, which made it possible for us to study the handling of shame. We found that our respondents tended to use different forms of accounts in order to handle the feeling of shame. We categorized them into five accounts with relating sub-accounts.

This paper investigates the relations between the fantasy genre and the phenomena of escapism. It also delves into the factors which motivates consumption of various fantasy mediums. This is done through interviews with six different fantasy-consumers, along with two observations; of which one is performed at a science fiction convention and the other at a table-top role playing game. The study resulted in a basic understanding of escapism ? it is not limited to the fantasy genre, and fantasy consumers do not deny that fantasy is a form of escapism.

Energy is today a very common topic, not only in Sweden but in the whole Europe. In EU they have given out a directive 2002/91/EG about buildings energy use and throw this they have forced their members to show how much energy their buildings use. In Sweden has the gouvernment established a law (SFS 2006:985) about energy declaration for buildings which demands that the building owner needs to show how much their buildings energy consumption are. Important to know is that this law doesn´t applies for industrial buildings.The report will show what the new law about energy declaration for buildings and appurtenant directions will mean for Riksbyggen. Also energy calculations will be done to be able to compare Riksbyggen buildings with the new law and directions.

Energy efficiency is important both to reduce costs and to reduce greenhouse gas in the atmosphere. In Sweden 40 percent of the energy consumption is related to the buildings sector. Hospitals are complex buildings with different activities in the same building, which requires flexible technical systems for ventilation, heating and lightning. A quarter of the total energy consumption in Swedish hospitals is related to user activities in the hospitals. Therefore it is not only important to work with operational optimization but also to change user activities, to reduce energy consumption.The objective of this thesis was to examine the user-related energy efficiency work at two care units, at the central hospital in Sundsvall within Västernorrlands County.
