This report is made as a literature review, focusing on the work done to increase understanding of efficiency in the categories of substations and secondary heating systems, with respect to the deviation from the theoretically possible cooling off in the distribution network as well as the economic benefit that appear. The main purpose of a considerable part of the literature used in this report addresses the issue of identifying individual causes of reduced cooling in district heating systems. These literature resources have been compiled and summarized as part of the report.The technology of district heating is associated with benefits such as better use of the energy in a fuel. This is the case of cogeneration plants where serial generation of electricity and thermal energy increases efficiency compared with the parallel generation where heat is generated locally and electricity is generated centrally. Serial generation thus allows for lower primary energy demand.

It is self evident that our society is an information one. This is true from the things we see around us.The world is now a global village.It just take seconds for communication to be established from one part of the globe to another.What a tremendous achievement for information technology.Among the recent developments of information technology is the scientific wizardary of cyber medicine.The internet has definitely revolutionalised the healthcare industry. Many people in developed countries of the world seek medical information, advice or even buy drugs via the internet.So many websites rise every now and then claiming to provide various medical assistance to patients. But the application of information technology to medicine poses some ethical problems today. It is because of this that cyber medicine attracts my attention in this research.With this research, I hope to offer some recommendations for a morally acceptable cyber medicine .This will help to some extent in solving this all important problem ofcyber medicine for the good of the health care industry and the society at large..

Many research reports mention the fact that a huge number of all system development projects never reach a successful ending; with other words never fulfil formulated goals. By identifying and forming success factors (and in some aspect risk factors) that the project manager in practice can use, this study may be seen as a step in the direction towards minimising the high number of failed system development projects. The purpose of this research report is to investigate how a system development project, where the development process is based on a specific development or process model (in this case the Waterfall model), can and should be driven. I aim to clarify what is demanded of a project leader for the specific development process and give an account for which eventual leadership qualities that can be well suited for given situation in relation to the need for technical competence. Among other things the project manager should inspire confidence, drive, be a decision maker, engage and own some form of basic knowledge in the field of system development.

This exam paper has been a collaboration between the writers and SYSteam Utvecklingspartner in Huskvarna. The assignment was about finding a need for a mobile application, making a requirement specification document with design documents and parallel to this constructing a prototype. The assignment is summarized in the following questions:? How can companies in the forest industry benefit from mobile information technology?? How can a user centered perspective be used in the process of making the requirement specification document and the design documents?? How do guidelines for usability apply to a mobile application?Three visits to companies in the forest industry were made to find a need for mobile information technology solutions. After a small analysis of the different companies? problems and conditions the decision was to use Tenhults Impregneringsverk AB in the case study.We used the FA/SIM method in our job of finding the organization needs for change and the principles of User Centered Design in the work of constructing a prototype.The result of our work is a requirement specification with design documents and a prototype.

The business potential of software defined radio (SDR) technology is studied by evaluating whether or not its characteristics correspond to those particular to a disruptive technology. The maturity of the SDR technology concept is illuminated by analyzing the opinions and perspectives of a selection of representatives for different stakeholders in the wireless communications market. Characteristics as, for example, the degree of consensus about the utility of SDR technology and the awareness of features and limitations are studied by application of the theory of technological frames. This theory helps us understand how and when technology evolution takes place. Finally we describe the value network structures of some potentially viable application areas for SDR and suggest some possible business opportunities based on SDR technology.This thesis is carried out as a case study and the research data is obtained from secondary sources, such as literature and Internet publications as well as interviews with people well experienced in the field of wireless communications.

Science and technology has been the bedrock of human growth and dynamism. Man has over the years distinguished his existence from all other beings by his ability to champion and fashion his existence. Among his tools is biotechnology which actually attenuates the fears of aging and death.Human reproductive cloning stands out as one of the means through which biotechnology plans to achieve this perfect existence for man. Technological advancements in the field of biotechnology are now in the threshold of human procreation.Human reproductive cloning is seen as an assisted method of reproduction which creates a newborn that is genetically identical to another human being.Human reproductive cloning as a technology and as a means of reproduction is not without its pros and cons. In as much as the technology promises to mention but a few, hope for the infertile couples and single parents, as well as the hope of reproduction without passing on hereditary diseases; it at the same time beeps some flashes of worry.

This thesis within the field of Integrated Product development at the Royal Insitute ofTechnology, performed at Primary Development Dishcare at AB Electrolux, is supposed to finda solution to enhance the hygiene inside an Electrolux dishwasher. The outcomes of this thesisare functional prototypes to evaluate the efficiency of disinfection by the use of Ultra VioletLight and Ozone.The thesis has followed Electrolux Primary Development process, with delivarables andcheckpoints.Ultra violett light with a wavelength of around 264 nm penetrates through the cell wall ofbacteria and micro organisms and causes a molecular rearrangement of the cells DNA. Thisprevent the bacteria from reproducing and it is considered dead. Commonly used UV-C lampstransmits the wavelength 254 nm which is very close to the optimum for germicidal action.A competitive brand have reacently launched a dishwasher claiming to achieve greaterdisinfection with an UV feature. This dishwasher was tested during the thesis and proven tohave a very low effect on the hygienic result.Two prototypes were devolped and tested for UV disinfection of dishware.

Industrialization of construction is by some considered to be a solution to the building industry's problems about the lack of quality, high production costs, low productivity and poor environmental adaptation. Meanwhile, industrialized construction partly earned a bad reputation after the million housing program. As large-scale projects where promoted during this period, it worked very well to use the technique of construction elements. In the mid seventies though, criticism arose which claimed that the aesthetic qualities had been deprived in the corporates effort to make housing production as efficient as possible.Tyréns, Derome and CBBT (centre for building and housing in wood) cooperates in a development project to develop a building system for 4-8-storey buildings, consisting of three platforms: a technology platform, an IT platform and a processing platform. The technology platform consists of flexible, industrially built flat modules of wood and from this platform the subsystem stairwells, is broken out.

This thesis work is intended to analyze whether the municipalities has a need for the new technology of mobile mapping.Mobile mapping consists of the technologies of laser scanning, photographing and positioning of streets and roads in city environment and in the countryside. When these technologies are operating together a georeferenced three-dimensional image model is created, which has specific coordinates that states its position on the surface of the earth. Thanks to the laser scanning process even measuring can be performed in this model.The municipal sector consists of many different departments which use visual spatial information. These departments are an interesting target group for this system. Specific departments within the municipal sector, which we considered were the most suitable, have been selected.

The attention on environmental issues has never been as huge as today. The climate is changing and more and more evidence suggest that the cause behind climate changes is an increase of carbondioxide into the atmosphere. The increase in turn is considerd to be an act of human activity. Therefore some companies have decided to become climate neutral and implement information technology in their business in order to reduce their emissions. This thesis has three aimes: to calculate a small company´s carbondioxide emissions, study whether or not information technology could help to reduce these emissions and furthermore find out why some companies decided to become climate neutral and describe the concept climate neutral.
