This thesis investigates if a system for small scale electricity production located in anurban environment can be profitable. The work has been divided up into two parts,one extensive literature study and one case study. The purpose of the literature studywas to investigate the area, resulting in a choice of which technology to be studied indepth in a case study.In the case study a system containing small scale wind turbines and photovoltaicsmounted on Gränby Centrums roof was examined. From data containing wind power,wind direction and total irradiation, possible production from a system weresimulated. Three products of each technology were examined in the simulations.From the simulated production an economic analysis was carried out, this toinvestigate if a system is profitable.

When I got the opportunity to write this examination did I want to write about something that I both was interest in and also can use in the future. I think it?s going to be difficult to carry on the milk production with only 28 cows. I wanted to investigate the possibility to increase the herd of cows. I also wanted to compare this cost with a new cow house the cows where milked with a robot.

This thesis aims to develop proposals and models for a modular electronics construction to a future D250S Dual battery charger. The aim also includes investigation of possibilities to use some of Texas Instruments C2000 microprocessors. The reason for this is that CTEK SWEDEN AB wants to renew the present D250S Dual battery charger and lower the manufacturing costs. The thesis work has involved gathering theoretical facts for the development of a design on the modular electronic construction, the choice on which microprocessor to use, the choice of electronic components and facts about peripheral equipment to the D250S Dual. With the theoretical there has been developed different solutions to the proposed hardware and software solutions with comparisons in aspects of positive and negative.

The aim of this report is to discuss computer security in handheld computers and to find out the appropriate security level that must be implemented to be able to use handheld computers within the Swedish healthcare system. Most healthcare centers are using some kind of electronic journals for their patient´s data today, but there are still a number of clinics that are usingthe old paper-system. On a few places in Sweden the use of handheld computers at the clinics has already started, but in the United States the use of handheld computers in the medical area is already widespread and from this we can see a lot of different situations where it is useful and effective to work with handheld computers. The security demands on patient´s journals are high and regulated in both Swedish law and regulations from the National Swedish Board of Health and Welfare. The law does not have any substantial demands, but states that there should be an adequate security level based on the nature of the information and the costs.

In most countries, the dairy industry focuses on the volume of milk produced instead of its composition. This results in a high content of water and a lower proportion of fat and protein. A high proportion of water is not desirable when processing the milk into various dairy products like cheese, cream and milk powder. High water content also increases the costs for transport and storage, and also an unnecessary, albeit marginal, strains on the world?s water reservoir.

Graphic profiles are a part of companies? brand expressions. The graphical values reflect the brand values the business wants to convey. They consist of different graphic elements such as logo, company sign, colour schemes, templates, rules, fonts, pictograms, formats and references to how different graphic elements should look, for example, business cards, signs and materials for websites. This thesis aims to examine why firms choose to replace their graphic profiles by studying their underlying motivations.

Every year more than 6000 thefts, to a value of 1.5 billion SEK, are reportedwithin the Swedish building trade. Plus all the indirect costs of having theconstruction site standing still.SafeTool is a newly started company that will try to prevent this problem witha modern technology solution.The key to SafeTool?s solution is RFID ? Radio Frequency Identification ? andthe solution looks like this;All tools are stored in a container on the construction site. Every tool isequipped with a RFID-tag that uniquely identifies the tool. With antennas in thecontainer it is possible to detect when a tool is leaving the container and whenit comes back.

AbstractGlobalisation has lead to changes on many levels of our society; -industrial, technological, and corporate to name a few. This is an ongoing process which affects the society we live in today. The process is affecting the working-conditions for everyone through the changes of the relations on the working market. The unions have enjoyed a very special role in Sweden for a long time, but that role is now affected by these changes. The relationship between state and unions is changing, and the unions? influence in politics is decreasing.

The shareholder is supposed to be indifferent if one share costs 100 SEK, or 10 shares cost 10 SEK each. In an efficient market, shares should be valued directly to new expectations as a result of the announcement of the reverse split. We investigate whether abnormal returns incur surrounding reverse split and if owner structure change.One reason for the reverse share split is that most companies have plans to imple-ment other company?s specific events in order to survive rather than to change the price range to a more attractive level. We found a negative return in the ex-day at 8,1 per cent.

Background: One of the main concerns related to medical therapy is non-compliance to drugs. More than half of all patients do not comply with prescribed medication. Non-compliance to drug therapy leads to unnecessary suffering for the patient and there are no easy solutions to the problem. In order to create understanding for the individual patient it is important that medical staffs are enlightened on the existing problems concerning this matter. Purpose: To describe factors that effect compliance to drug prescription.

Internet and digital technology has changed the way we live our lives. As individuals we've found new ways to communicate, educate and experience. But what's the effect on B2B marketing? Previous research presents transactional benefits such as lower costs and easier access to information, but there is limited research done on more complex and long term relationships as well as on modern digital tools. The purpose of this thesis is to investigate whether a deeper long term B2B relationship can be created and nurtured using digital tools for communication, and if so, how these tools and processes can be described and understood.

Today there is a widespread opinion that the woodmarket and the forest industry are dominated by a traditional way of thinking and not adapted to the customers of today; a lot of products are produced purely on routine. Also, there is a demand for improving the quality of sawn woodproducts. AB Karl Hedin wants to sort this out by increasingly adapt their products to the demands of the market, i.e. through introducing a short wallstud of standard length, "Hedinregeln". At tirst, the wallstud will be produced in lengths of 2,70 m and of guaranteed quality.

During the last few years the alcohol consumption has increased and is now the highest in 100 years, one usually count that 10 % of the grown up population abuse alcohol and/or drugs and most of them are hidden abusers with families and work. This leads to great costs for the companies. But the much greater cost for the companies are the much larger group of risk abusers. According to the Swedish law the employer has a responsibility for the work milieu and also for the rehabilitate for the employed and drug/alcohol abuse applies to this.I have done qualitative interviews on four companies in the south of Sweden with one representa-tive for the management and one representative for the union. I have investigated their attitudes to alcohol and drugs and how they describe the alcohol culture at the company.The companies define alcohol problems when they are established and obvious and when it is dis-covered they put in resources and because of this they don't work preventive so much.

The background to this study is to find alternative ways of size rationalization. My vision is to take the basic conditions and make the best and most profitable of them. I have chosen press of rape oil because it?s interesting and the investment to get started is relative small. The opportunity to use outmoded and unrational buildings which often are found at many farms to something that gives money instead of costs money is also an argument.

Today electronics becomes more and more complex and to keep low costs and power consumption, both digital and analog parts are implemented on the same chip. The degree of automization for the digital parts have increased fast and is high, but for the analog parts this has not come through. This have created a big gap between the degrees of automization for the two parts and makes the analog parts the bottleneck in electronics develop. Research is ongoing at Electronics systems group at Linköping University target the increase of design automization for analog circuits. An optimizationbased approach for device sizing is developed and for this a good optimization method is needed which can find good solutions and meet the specification parameters.
