This report is regarding an electrical installation of an alarm system on a post fishingboat called Andromeda. The background of the installation was an earlier andinadequate alarm system that led to a motor failure. The ship was taken out of serviceand was sold to Björn Magndahl who rebuilt it to a yacht.The project was conducted partly by developing the existing systems, partly bydocumenting the work by means of electrical blue prints. Except the alarm systems, aninstallation of the frequency control unit for the bow thruster was installed.The installation was working fine and the outcome of the documentation was handedover in a form of a binder during the test drive of the systems and the assignment wasapproved..

Information handling has been a key issue for different companies for a long time. Electronic Data Interchange (EDI) is used to transfer different business documents from one company to another. This is done in such way that the information itself is separated from how this information is stored and handled in the companies internal systems. As different companies have different systems there is a need for a standardised format for this exchange. There is a big difference between EDI-systems based on what kind of EDI-standard is used. The most common standard in Europe is EDIFACT, but with increased interest of using the Internet for business communication there is a need for a standard that is adjusted for use over the Internet.

Automatic query expansion has long been studied in information retrieval research as a technique that deals with the fundamental issue of word mismatch between query and document. The purpose of this thesis is to compare the retrieval effectiveness of different strategies for automatic query expansion. The strategies are based on local analysis of the corpus and use statistical information from the local document set to extract terms that suppose to adapt themselves to each individual search and therefore appear to be searchonyms to the index terms. The strategies compared are: association clusters, metric cluster and scalar cluster. Baseline queries of 24 topics are expanded using terms from the different clusters and searches are made.

Swedish dairy production has during the last decades undergone considerable structural rationalisation and the number of dairy herds has decreased to less than 7000. At the same time the average herd size has increased and a large proportion of those investing in new buildings today choose automatic milking (AM). During 2008 more than ten percent of the Swedish cows will be milked with AM. The development has been faster than expected and the need for consulting has increased rapidly. This study aims to evaluate whether a check list originating from the FRISKKO (?healthy cow?) programme can be a useful tool when assessing how well the herd functions in various areas.

The decomposition of organic carbon in drained peat soils is a major source of carbon di-oxide in Sweden. A big part of these drained peat soils are used in agriculture and it is a big challenge to slow down their decomposition. It has earlier been thought that less tilling and higher water table levels would decrease the activity of soil microbes and thereby the decomposition, but recent experiments has showed that this has little or no effect. In this bachelor thesis a field experiment was made on drained peat soil with ley, outside Björklinge, Uppsala municipality, Sweden. The experiment was carried out in May 2011. The objective was to develop a method to examine how the net exchange of carbon diox-ide from plant covered peat soil is affected by temperature and photosynthetically active radiation (PAR).

This report is about the impact climate change has on the water and sewage systems in general, and the situation in the municipality of Karlstad in particular. Which vulnerabilities are linked to water and sewage systems with regard to climate change and extreme weather situations, what are the possibilities to adapt the system to this and what significance does climate adaptation of the water and sewage systems have in relation to sustainable development?To answer these questions I have studied literature on the subject and interviewed several people who work with these types of questions. The answers I have received state that there are a multitude of vulnerabilities linked to the water- and sewage systems, but that there are also many strong interests which strive to take measures and adapt to a changed climate. I have also come to the conclusion that the starting points and views of the possibilities to act differs between the people that I have interviewed, but that theses problems are built into the concept of democracy..

Agencies towards Sustainable Development ? A Study of Environmental Management Systems in Governmental Agencies 2005A vision of the Swedish government is to build an ecologically sustainable society. A tool in this effort is to implement environmental management systems (EMS). The aim of the thesis is to present in which phase of the implementation of EMS Swedish governmental agencies are. This will be done by compilation and evaluation of agencies? yearly environmental reports.The thesis is written in co-operation with the Swedish Environmental Protection Agency (Swedish EPA).

During the last decades the Swedish local party systems have gone through some considerable changes. The number of parties present in local party systems have increased and in some cases even doubled. This makes coalition building between parties complex and parties will be forced to rethink their coalition strategies and adjust to the new circumstances. Theoretically, coalition building has often been considered and applied to national data and there have been just a few attempts to develop and theoretically explain coalitions on a local level. Thus the aim of this paper is to use different theoretical approaches to local data to test the significance of traditional coalition theories.

In today?s world there are plenty of technological tools and methods available with the purpose to increase peoples motivation for a healthier lifestyle. One such tool is a so-called activity tracker which uses sensors to log the user's everyday life and present it as automatic feedback. Gamification is a new and successful method to motivate and engage people in fulfilling tasks by using game elements and mechanics. In this study, five participants were instructed to use the activity tracker and pedometer Fitbit Flex daily for three weeks. Halfway through the study the participants were ranked and listed against each other in a ranking list in order to evoke competition.

The purpose of this thesis is to investigate if there are environments that use some kind of central authentication system within institutions/schools. The hypothesis is that an institution not using a form of central authentication service has more need for maintenance and as such is considered a higher cost for the organization. The gathering of data has been done through interviews with technical personal at Blekinge Tekniska Högskola and Linköpings Universitet. Based on the technical background of the authors, and the system limited to discussing Windows and UNIX operating systems, a discussion and analysis of the systems working today has been done, with emphasize on the hypothesis..

Wavecraft AB develops medical equipment for heating of organic synthesises. The heating is done with microwaves, which improves the process in both speed and accuracy compared to the more traditional methods where heating elements are used. This report discusses the developement of an automatic lid mechanism for one of Wavecraft's product prototypes. The company assumes that the final product will be integrated by customers into fully automated systems, and the upgrade from a manually to an automatically controlled lid is therefore an important step in the product's developement process.The first stage och the project was an idea generation process. The ideas generated here were organized into five different concepts of which the best one was selected through the use of a concept matrix.

The aim of this thesis is to describe and evaluate the usability of two Swedish systems, Sofie and Carlotta, which are used to organize and present data regarding museum objects on the web. This thesis also presents how objects are described and made accessible to the public in the two systems. To evaluate the usability, a heuristic method combined with Systematic Usability Evaluation has been used. The description and accessibility of object representations in the systems are evaluated using indexing and classification theories from the field of Library and Information Science. Additional theoretical background that has been used is how users search and browse information systems.

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).

This thesis deals with classification of the subject field history of medicine. The two classification systems SAB and NLM are compared in order to find out which one is the most adequate to organize a small collection of history of medicine. SAB and NLM are the two most commonly used classification systems in medical libraries in Sweden today. NLM classification system specializes in medicine and SAB is a universal classification system. Our purpose with this study is to find out the pros and cons of each system, whether the systems treat the subject history of medicine in a satisfactory way and what kind of classification system that is better for this assignment, a specific one or a general one.
