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..

The main purpose of this thesis is to investigate hospital librarians understanding of their professional role in working with children. Two different aspects of the professional role were focused on; professional knowledge and ethics. The following research questions were posed: - How do hospital librarians experience their professional role in working with children and young people? - What is regarded as professional knowledge content for hospital librarians in working with children and young people? - How do hospital librarians view ethical aspects in working with children and young people? The issues have been addressed through qualitative interviews with seven hospital librarians. We have used phenomenography which is both a set of theoretical assumptions and a methodology.

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 ethical aspects of the Swedish Curriculum for the non-compulsory school system, Lpf94, will form the basis of the research in this essay. The ethical aspects constitute fundamental values and goals as well as common tasks that must be carried out by every teacher. Since the school debate focuses a lot on this perspective, which is often mentioned together with the words problematic and contradictory, it will consequently also be the focus of this essay. Here these features are treated in relation to literature in all its forms used by teachers in class, which also represents a part of the school debate. Together ethics and literature form a perspective that lacks research.

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..

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..

The purpose of this thesis is to get a better understanding of consumers? perception and knowledge of Fair Trade and Fair Trade products in Sweden. Literature was reviewed before the empirical research was conducted. A quantitative method, in form of a questionnaire survey, has been used. We have entered different areas related to our topic.

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.

An employee that informs on illegal or unethical behavior in the workplace is what has been called a whistleblower. Employees that have become whistleblowers have often faced tragic consequences, like threats from the organization, unemployment, bankruptcy and divorce. The purpose of this paper is, on the basis of different ethical perspectives to describe the justification of the whistleblowing phenomenon and apply this to the Swedish whistleblower Ingvar Bratt who ?blew the whistle? when he found out that Bofors AB, the company he worked for, were smuggling arms to the countries Dubai and Bahrein. The method that has been used in this paper is what Björn Badersten call a normative ?givet att?- analysis.

The objective of this work was to evaluate and implement a number of energy saving functions for a specific embedded system. The functions were then grouped into a number of energy levels with known properties in terms of functionality, energy consumption, and transition time between the levels.The embedded system consisted of an AT91 ARM9 processor, GSM/GPRS modem, display, Ethernet and other peripheral units. Some energy saving methods that were considered were suspend to RAM, suspend to disk, frequency scaling, and methods for saving energy in the modem, Ethernet, USB and display backlight. The functions were grouped into levels and an interface was specified for controlling the energy level.It proved possible to get known properties within the defined energy levels, even though the paritioning of functions into these levels proved to be sub-optimal in a typical application usage scenario because it was designed for mainly energy consumption, not usage.The final result is a number of energy saving functions grouped into levels, which are controllable via an application interface. Each of the levels have a known energy consumption in both loaded and un-loaded mode..

The aim of this study is, using the Swedish expression ?kulturtant? (cultured lady) as starting point, to understand how and why women consume the products of the culture industry more eagerly than men. The study is using the concepts put forward by Pierre Bourdieu; fields, capital and habitus. It is a qualitative study based on discussions in focus groups, interviews and material gathered through Google Alerts. In the literature this gap between the sexes with regard to the higher consumption on behalf of women has been referred to as the ?puzzle? of women´s cultural consumption.The empirical results show that the women in the study are well aware of what they want to gain by participating in cultural activities like reading, going to concerts, watching plays or going to the movies.
