AbstractThe assignment were assigned by Camatec Industriteknik AB. Camatec is a Karlstadlocated consulting company, they make everything from pilot studies to complete projects in mechanical design and calculation. They even have their own patented product, Camcoil. It is a winder for steel strips and is used for example with hardening of the steel strip. The assignment has been to solve the problems encountered by some customers within this product.

Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.

In the process laboratory of Metso minerals (Sala) AB, continuous tests have been made with a laboratory unit High-Rate thickener. The tests are made in order to compare three methods of thickening techniques of suspended solids. The three techniques are High-Rate thickening, conventional thickening and lamella thickening. The High-Rate and the conventional trials are based on a continuous method, while the lamella thickener is based on batch trials. Because the lamella thickener is based on batch trials and there were some optimization problems with the adding point of the flocculant at the continuous trials, it was not feasible to compare the lamella thickener with the other two thickener types.

At the end of 70s and the beginning of 80s, 18 terminals was built and used for chipping wood residue from clear cuttings. Most of the terminals was terminated before the 2000s but with the high oil- and energy prices that we can see today there might be a place for these terminals again. The goal with the study was to analyze and compare economical differences between 5 different logistical systems, collected data was used with a set of formulas. The systems include long range transport of slash, chips and bundles. Three of the systems include transport by lorry to industry the last two includes a terminal with access to train transport.

Background: With the increased globalization food prices went down for a while, only to skyrocket to new levels. Prices of organic food, which already were more expensive than conventional, are now even more expensive. The current financial crisis results in reduced consumption which creates a threat to the smaller grocery stores. Globalization and the increased competition have had a negative impact on the environment but at the same time the desire to solve these issues has increased appreciably. The environmental aspect has been given higher priority by the individual, which led to a wider range of organic products and dramatically increased the number of stores selling organic products, leading to a greater competition among the stores selling organic food.  Problem definition: What factors are important for organic retail business long term survival?Purpose: Trough case studies analyze and evaluate the organic niche retail companies? strategies of marketing.Methods: This study is based on both qualitative and quantitative research methods.

The purpose of this master?s thesis is to examine how librarians perceive the importance of staff reading groups in helping to make fiction more accessible to adult users of public libraries. The study also examines how librarians perceive the learning processes in such groups, and what these learning processes involve and how they appear. The empirical data was acquired via observations of four staff reading groups and interviews with seven public librarians who took part in the groups. In part, the empirical data is interpreted by means of Lena Wilhelmsson?s analytical tool, which deals with changes of perspective within an organised group.

Background and problem: Whether or not the pay to executives is fair is widely debated. During the last years especially the variable pay has been in the spotlight. But at what levels are the compensations really at? Media?s focus is mainly on the absolute highest compensations which may result in a skew view on pay-for-performance incentives.Purpose: The purpose of this thesis is to establish the levels of compensation to executives in a wide range of randomly selected companies listed on the Stockholm stock exchange during the years 2001 to 2005. Furthermore, the impact of a set of firm specific variables on compensation levels will be analyzed with basis in several hypothesis.Delimitations: The variable pay considered in this thesis will only be variable cash bonuses.

Deferred shading är en renderingsteknik som har blivit allt mer populär i och med att hårdvaraukraven för tekniken inte längre är ett hinder. Ett problem med deferred shading är fortfarande hur transparenta objekt ska hanteras. Rapporten utvärderar två olika deferred pipelines som hanterar transparent geometri på olika sätt, de två renderingsmetoderna är Inferred Lighting samt Light Pre Pass med framåtrendering för hantering av transparent geometri..

Smarta elnät är en av lösningarna för att uppnå EUs klimatmål den s.k. 20-20-20-satsningen. Klimatmålen innefattar bl.a. ökad energiproduktion från förnybara energikällor och ökad energieffektivisering, detta anses nödvändigt för att hindra den globala uppvärmningen samt uppnå en bättre och mer hållbar framtid. Den elektriska energins svaghet är den begränsade möjligheten till effektiv och storskalig lagring. Eftersom den förnybara energin har en väderberoende produktion ska smarta elnät hjälpa konsumenten att styra energikonsumtionen efter hur energiproduktionen varierar.

The purpose of this thesis is to test whether firms have target capital structure, and if so with what speed they adjust toward this target. Findings that support this purpose are also in line with the trade off theory. One of the key elements of this thesis is the method used, which successfully enables fulfilling the purpose. The panel data method captures the data characteristics of the cross sectional and time series dimension. By using this approach the dynamic effects of capital structure can be studied, thus if there actually is an adjustment towards a target the speed can be estimated.

This thesis is seeking to explain why policy change come about. This is done by applying a part of Karin Lindgrens dissertation Vad styr ledaren?. The research evolves around the term pressure and the hypothesis are that policy change come about when there is middle range pressure on the decision-maker. Low and high pressure results in no or small policy change.The thesis is done as a case study where the economic crisis in Thailand 1996-1999 makes my case.

This study will analyze and interpret the performance art piece The Last Strawcreated by the artist group High Heel Sisters. The aim is to search for potentialfeminist strategies in their deconstructive ways of incarnating gender and bodiesusing the notion of performativity and phenomenological theories.My study shows that the diversity of this art performance creates a complex platformwere discussions about gendered corporeality and spatial power relations are beingnegotiated..

The purpose is to analyze if the students have any use of their computer education at a senior high school level or if there is a demand for them to proceed studying. Does the students background have any importance or is it their own motivation that makes the student advance to higher education.In this report we ask ourselves the question, if the students have any use of the knowledge gained at senior high school in computer studies at a higher level. Do the students have any chance for employment based on their senior high school grades in computer studies after graduation?  Do the schools that follow the senior high school guidelines within programming and databases give these students an advantage towards those that have not received the same fundamental education?The method used for the survey is a group questionnaire.  The questionnaire was distributed at one and the same time and then collected to examine the results. The survey results showed that students who seek work based only on their senior high school grades, received only a temporary position for different lengths of time.

This thesis presents the results of the implementation and evaluation of two machine learning algorithms [Baz98, GB97]based on notions from Rough Set theory [Paw82]. Both algorithms were implemented and tested using the Weka [WF00]software framework. The main purpose for doing this was to investigate whether the experimental results obtained in [Baz98]could be reproduced, by implementing both algorithms in a framework that provided common functionalities needed by both. As a result of this thesis, a Rough Set framework accompanying the Weka system was designed and implemented, as well as three methods for discretization and three classi cation methods. The results of the evaluation did not match those obtained by the original authors.
