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.

The Swedish Government has set a target to reduce energy consumption through energy efficiency within the construction and real estate sector. The purpose of the study is to examine how energy efficiency within this sector could affect the district heating volume in the future, on basis of Vattenfalls district heating system in Uppsala.An Excel model has been created to study how energy effficiency measures affects district heating demand in buildings by 2045, based on technical and economicalconditions. Furthermore, an interview study has been conducted to examine incentives for district heating customers to invest in energy efficiency measures.Result of the Excel model shows that the district heating volume of Vattenfall in 2045 is expected to 931 GWh, which corresponds to a volume decrease of 10,6 %. Based on the study?s theoretical framework only 15 %, 1 024 GWh, of the technical-economical potential is assumed to be implemented.

The aim of this study is to examine possibilities and barriers for an introduction of electric vehicles in Sweden. The study has an interdisciplinary approach and thoroughly examines the essential topics which influence the future of the electric vehicle. The study reaches from answering the question on why electric vehicles lost the game to petrol cars in the early 20th century, to sketch how the difference in total cost of ownership will be between electric vehicles and petrol cars for the coming 20 years. Apart from these subjects the main topics of the study are today?s and tomorrow?s situation regarding technology, charging, fuel, market and economic incentives from an electric vehicle perspective.

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 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.

Background: An evaluation of analysts´ forecasting ability is interesting since their estimates constitute an important part in stock valuation and investment decisions. The recent years´ development in the stock market has lead to criticism of analysts? deficient forecasts. Purpose: The purpose of this thesis is to evaluate analysts´ forecasting ability concerning companies quoted at Stockholmsbörsen between 1987 and 2002. We also intend to discuss possible explanations for analysts? behavior in case of deficient accuracy.

This study examines the effects of credit risk and information disclosure in the new bank regulating system Basel II on bank and bank customer. The effects are then discussed in a perspective of the economic man and information asymmetric theories. Furthermore is the Basel II effects on the capital adequacy of Andelsbanken för Åland examined.The approach of the study is qualitative and several interviews with individuals on different levels of the examined bank, Andelsbanken för Åland, have been carried out during the collecting of empirical facts about the effects of the regulating change from the Basel I system to Basel II.The research findings are as follows:Andelsbanken för Åland have increased its capital adequacy ratio from 12,7 percent to 14,4 percent, mostly due to lower risk weights on housing mortgages compared to Basel I. Andelsbanken för Åland have started to use a completely new credit risk and customer assessment system which classifies every customer and gives them a credit rating. The system cause a much heavier information gathering of the customers profile as well as a much better assessment of risk than the previous system, which the bank finds positive.

The use of balanced scorecards have spread explosively throughout the world during the last decade. This management tool have become very common in a vide spread variety of organisations on all continents. Many balanced scorecard fails though and scorecard theorists often blame the identification- and implementation process as they claim that these lay the foundation for the use of the tool. As my literature study shows, academic research on the area is rare. Particularly the effect on the implementation process from organisational dynamics and organisational structures needs further research.

Exporten har en betydande roll i dagens samhälle och verklig påverkan på landsbygden och dess framtida möjligheter till överlevnad i ett urbaniserande och teknikfokuserat Sverige. Det är dock inte helt enkelt som enskilt, mindre företag att exportera sina produkter. Detta arbete syftar till att lyfta fram framgångsfaktorer hos livsmedelsföretag som redan är väletablerade på den internationella marknaden och som under en tid har bedrivit en framgångsrik exportverksamhet. Det är en kvalitativ studie och det empiriska materialet är baserat på tre semistrukturerade telefonintervjuer med livsmedelsföretag från Halland och Skåne. Begreppen resurs, nisch och ??Dynamic capabilities?? samt ramverket VRIO har varit viktiga vid analysen.

In this essay a model of a potential illegal hunter?s decision-making is created and presented in order to provide an overview of important parts of the complexities associated with the current Swedish predator policy. A comparison is made between a livestock owner?s economic incentives, and the expected costs faced by the potentially caught lawbreaker. In accordance with economic theory the benefits and costs of illegal hunting are compared and thus the optimal choice is determined where marginal costs and benefits are equal.

In a business environment where the stakeholder perspective is evolving and sustainable development is receiving increased attention, it is of importance for companies to adjust. The demand and pressure is exerted from several stakeholders who force companies to take action and live up to the expectations because if failing to do so, negative consequences will most likely be the case. The attention of this study is on ABB Power Products (ABB PP) and their environment and working environment risk management. The aim of this thesis is to identify and describe how perceived environmental risks are managed and what the incentives are to work proactively to minimize the risks. The incentives for a proactive risk management strategy are researched through both a strategic and operational perspective.
