n this dissertation a comparison of two evolutionary methods for evolving ANNs for robot control is made. The methods compared are SANE with enforced sub-population and delta-coding, and marker-based encoding. In an attempt to speed up evolution, marker-based encoding is extended with delta-coding. The task selected for comparison is the hunter-prey task. This task requires the robot controller to posess some form of memory as the prey can move out of sensor range.

This study is based on an ongoing debate regarding the Stockholm Stock Exchange, which centers around the possible abolition of quarterly reports. The purpose of this paper is to contribute to this debate by examining how the relationship between financial reports and stock price correlates. The study's methodological approach is based on the Capital Market Research frame-work in which an ERC model and an extended model are used to measure the relationship. Three hypotheses were formed to categorize the direction of the study, these categorizations treats the differences in impact between quarterly and annual reports on stock price, as well as differences in impact as a casual effect of company size and seasonal sensitivity. The results of the study show that quarterly reports have a stronger impact on the share price than annual reports.

There is a known link between relative deprivation and street crime among market liberal countries. Although some research has been done with cross-national data, there is none to suggest that the observed link is as valid in a country well known for its extended welfare and generous social expenditure like Sweden. The following study uses longitudinal data to see if this recognized link between relative deprivation and street crime also stands in a country with almost a century long tradition of striving for social-, economic- and cultural equality. Even though Sweden, over the last decade, has been subjected to a series of deregulations due to policy changes at national level, and with a following rise in inequality, it is still considered to be one of the most equal countries in the west. It is therefore not unlikely that the high degree of social security will reduce the negative impact of relative deprivation on social relations among its citizens, perhaps enough so that the correlation will be significantly weakened.

This thesis concerns partial discharges in stator windings and the possibility of analyzing data using statistical methods. Partial discharges, or PD, are a physical phenomenon in which discharges occur locally due to large electric fields. PD can occur in or adjacent to the insulation of stator windings and causes breakdown of the insulating materials. PD measurement can provide an idea of how widespread the PD activity is. A technique to measure and analyze PD that has become very popular over the last few decades is phase resolved PD patterns.

The purpose of this study is to examine the effects of joint venture announcements on stock prices behavior and simultaneously to test the German stock market (Frankfurter Wertpapierbörse) for efficiency. We tried not only to analyze the general impacts of a JV-announcement but also to look for differences in the market response to announcements of different types of joint ventures, namely: domestic, international, horizontal and vertical. Our expectations of efficient market were confirmed during our paper, which employed the technique of the standard event study. The calculation of abnormal returns which are the signals for market efficiency or inefficiency respectively were based on the market model, establishing linear relationship between the return on the market and the return on an individual security. The parameters of the model were obtained through regression analysis..

Veterinary hospital care and advanced veterinary services are rapidly growing industries. As of January 1, 2010, veterinary nursing became a licensed vocation, the title of veterinary nurse became protected, and the act regulating competence among the professions of the veterinary field was extended. These changes, along with increased demands and expectations from owners, have given rise to greater demands on the staff's qualifications and have increased the need for well-educated staff with expertise in several different areas. The aim of this study was to find out what the licensed veterinary nurse can do in terms of rehabilitation for the hospitalized equine patient suffering from orthopedic injury. This has been carried out through qualitative interviews with veterinary surgeons experienced in treating such patients, and also by reviewing the relevant literature.

Literature describes what it is like to be a leader in the healthcare and what is looked upon as the most characteristic quality for female leadership. Women often use a leadership technique that motivates the employee and they allow themselves to develop a humanitarian leadership. The aim of this study was to describe female head nurses? experience of their leadership in healthcare. The collection of data has been carried out from interviews.

This project was about the creation of a shorter computer animated film. Thegoal of the project was to explore a different technique of the visual outcomethat should not rely on photorealistic rendering and how to find new interestingways to use 3d-graphic for visuals. A big part of the project was also toincorporate music to create a chosen atmosphere and impact on the viewer butalso to help the story forward and questions such as; ?How can you create anexpression for the feeling you want to transmit?? were formulated. The scenewas built up in a 3d-application consisting of a house and surrounding garden,which within an character was animated to tell the plot.

This paper investigates the possibilities to construct automatized portfolios based on optimizations strategies that could outperform comparable indexes. The study is based on time-series of Swedish stocks dating from 1986 to 2006. In the research four different portfolio optimization techniques were studied. These were: the Classical Markowitz Approach, Mean-Absolute-Deviation, Minimum-Regret and Conditional Value-at-Risk of which the three latter are based on generated scenarios. The behaviour of these models was studied for different choices of parameters such as backward time-horizon and targeted average return.

Our aim with this study has been to show the central factors that we consider have had animpact on public libraries in the "information society". We have studied two communities in the south of Sweden, Ronneby and Sölvesborg. These two communities have both started a development to the IT society, a society where information plays a great role, where the technique is the tool that supplies information.Ronneby community had early the aim to be the chief Swedish information center. A priority on information technology has therefore been obvious for them. Sölvesborg community has had another method and time schedule towards the IT society.We have been studying the documentation of aim and the strategy for IT development in different levels.

This report is about helping Q-Med AB in Uppsala to start its implementation of uncertainty of measurements analyses in their manufacturing department. Prior to this, the company relied solely on personal experience or did not take this uncertainty into consideration at all during different kind of measurements, which means that some of the processes that the company previously believed were within specified acceptance limits, will actually fail when considering these sources of uncertainties.Q-Med AB needed some sort of instruction to help the company, in a systematic way, to investigate different types of disorders that are affecting all kinds of measurements. This instruction includes a short summary about measurements and uncertainty of measurements in general and a detailed procedure about how these uncertainties are going to be handled in their daily work.The goal was to be able to use this instruction to systematically locate, eliminate (when possible) and analyze all kinds of disorders when measuring. Q-Med is using a lot of different types of instruments when measuring different types of quantities, including temperature, mass, pressure and density. This instruction will hereafter be used for every instrument, regardless of quantity and type of instrument.The instruction is tested through 4 different kinds of measurements, for mass, temperature and humidity.

What is discussed here are the events taking place in Sweden in 1885, a turbulent year in Swedish art history. It is shown how the conception of Swedish art, in creating a Swedish identity in art, was expanded.  Two exhibitions were analyzed, Akademiens för de fria konsterna Jubileumsutställning and Opponenternas utställning. While the artists exhibiting at the Academy were using traditional strategies and thechniques, several artists at Opponenterna, were using modern techniques they had learned outside the Academy, mostly in France. These techniques were: experimenting with perspective and the use of empty spaces in mediating ambiance. The third strategy was that of individualization by moving closer to the motif.

In printed text, sound is a somewhat forgotten aspect. The recitation of text is vital in areas like poetry and oratory, but still has no distinct technique of being communicated. Emphasis of a word might be expressed through italics, but no canonic character set or system for vocal delivery of texts exists. With this essay we are creating a foundation for a development of such a character set or system. By studying existing visualisations of sound and comparing these with semiotic and perception-based theories we obtain useful insights for a prospective system for visualisations of vocal sounds.We conclude that the aspects of sound one wants to visualise must be carefully defined since the viewer cannot process infinite amounts of information.

Regulation of web bots is an analysis of the interest and a collection of discussions about the phenomena web bots. The section that contains the result from the interviews brings up the question about ethical and legal actions and the opposite to those. How the regulation could work is also discussed in the section with the results from the interviews. The discussions were produced by people whose background in one case or another can relate to the phenomena web bots. In that way this study was limited to few, but more profound interviews which would enable analyses of web bots existence.

The purpose of this essay is to study how the local creators of a "master plan" for the swedish city Kristinehamn, the years between 1940 to -43, looked on their planning. It is an analysis of ideas case study. A hypothesis is upheld for the research: that the local physical planning had largely extended ambitions what regards central state control in a way that is similar to planned economy. Questions that are asked include: Was the planning assumed to be a tool for the state to regulate the environment? Can the planning be seen as a mean to control the society in time and space? The essay search for verification of the hypothesis by a theoretical analysis apparatus made upp of ideal types.
