The voltage level in the power grid varies due to variations in load and production. Normally these variations are manageable, but they may be excessively large during a disturbance. If the voltage is too high it may damage the equipment in the grid and too low voltages may cause problems like voltage instability. The magnitude of the voltage variation depends on the short circuit power capacity of the point of interest.This problem may become lore prominent due to automatic voltage regulation that acts on shunt reactors and shunt capacitors. When the shunt reactor is connected or disconnected to the grid it may cause such large changes in the voltage that the shunt reactor starts hunting.

Today an increasing number of schools and organizations are investing in so called Learning Management Systems. Researchers disagree on the pedagogical value of these tools. Some mean that Learning Management Systems cement old-fashioned behaviouristic teaching practices; others mean that the systems provide good opportunities in supporting learning in a socio cultural perspective. The aim of this study is to reach better understanding and increased knowledge of how the introduction of a Learning Management System influences the role of the teacher and how the learning is organized. We have conducted two case studies.

During the past few years an increased attention has been paid to environmental issues in the construction and property sector in Sweden. In order to simplify the work with these issues a Swedish environmental certification system for buildings called Miljöbyggnad has been developed. This thesis aims to investigate the opinion of a selected number of selected property owners of Miljöbyggnad. From that basis recommendations and actions for the future work with the system will be presented.The investigation has been conducted through personal interviews with five property owners. The main issues that the interviews have been based on are their purpose, experiences, perceived complications and future prospects in terms of certification using Miljöbyggnad.The system intends to be cost-effective, simple and to offer a relevant environmental assessment of buildings and the result from the report indicates that this is largely fulfilled.

Recent accounting scandals, often led by managers trying to improve results and thereby their own bonuses, have severely damaged the publics view of management. In the aftermath of scandals such as Enron, Parmalat and Skandia, demand has increased for Corporate Governance codes and similar regulation. The Swedish code for Corporate Governance came into effect on July 1, 2005. The code requires all Swedish companies listed on the Swedish Stock Exchange (OMX A- and O-list), with a turnover exceeding 3 billion SEK, to disclose a report regarding Corporate Governance, attached to the annual report.The purpose of this paper is to examine whether the new disclosure required by the Swedish Corporate Governance code will have a measurable effect on stock prices. The authors have applied event study methodology examining daily returns around the announcement of the Corporate Governance reports.

The background of this study is an article in the hunting magazine ?Svensk Jakt? where Karl Hedin claims that his sawmills has not noticed any significant moose damages in the timber. The purpose with the study is to find out the causes to the moose explosion and what it has led to in today?s forests. A questionnaire has been sent out to sawmills in the region Dalarna with the purpose of finding out if sawmills receive moose-damaged timber and what they think about how they foresee future development. There were two causes of the moose explosion, that had effects on the moose population. The first cause was that the moose hunters wanted to raise the moose population, and by raising the calf shooting and by saving the cows they succeeded. The second cause was changing methods in Swedish forestry.

One of the main tasks of the Swedish Armed Forces over the past few years has been International assignments, which increased the importance of the Lessons Learned process. Methods of simulator training with computers have become more frequent and the technical ability to collect digital data from sensors has been developed as well. This work demonstrates how the experience of Lessons Learned can be communicated with the computer simulator StriSimPC and how modern technology in future support experiences from the Lessons Learned process at the tactical level in the Army.Currently knowledge sharing consists of several processes and strategies in the Swedish Armed Forces. This is done by written reports, oral presentations and different practical exercises.This case study shows the functions of the simulator StriSimPC, methods of training and how it is used today. The study also describes the future opportunities, where digital metadata acquired from the modern combat vehicles could contribute sharing of experience in the Lessons Learned process.The summarized conclusions indicate that StriSimPC can combine the two strategies for personalization and codification of knowledge transfer to reach a higher level of learning.

The problem area was identified due to the fact that research within internal audit is fragmented and insufficient, simultaneously to internal audit becoming more common in the public debate. Crises and scandals in companies such as Enron in the US and Skandia in Sweden have resulted in new regulations regarding how companies should be governed. These regulations have been established in Sarbanes Oxley Act (SOX) in the US, and in Sweden the Swedish code for corporate governance will be implemented in 2005. The regulations imply that companies must provide sound internal control and to accomplish that, companies should have an auditing and consulting internal audit function. The Swedish code for corporate governance denotes that companies can decide to comply or explain why the code is not complied.

Detta examensarbete utfördes på Saab AB, Support & Service, i Tannefors, Linköping, samt vid Institutionen för datavetenskap på Linköpings universitet. Ett moment i kvalitetsarbetet för komplexa industriprodukter, som till exempel flygplan, är att skifta från tvådimensionellt konstruktionsunderlag till tredimensionellt. Tredimensionella modeller har funnits i flera år. Nackdelen med dessa modeller är att de inte kunnat bära någon extra information, förutom den information som krävs för att de ska vara uppritade. Tekniken har gått framåt och nu går det att lagra teknikinformation i modellerna samt göra simuleringar som inte gått att göra förut.

The purpose of this essay is using theories about labeling and social bonds to study whether a measure of rehabilitation for the psychically disabled contributes to a return to a normal status as not-labeled. Partly we examine whether the activities organized by the regulation-ruled authorities during the work of rehabilitation lead to shame or pride, and partly how these activities are organized regarding the processes that lead to the emotions pride or shame among the participants. Method: qualitative semi-structured face-to-face interviews with professional rehabilitation-actors at the Public Employment Office (PEO), the Social Insurance Office (SIO), the Social Service (SOS), the Psychiatry and the Division of Labour Market (AME).Conclusions: the Psychiatry clients are treated with respect, may participate, and communication is characterized by attunement, therefore strong social bonds can be built. On the contrary, among the other examined activities, we found many elements that arouse shame. Since these are more ruled by regulations, the result is engulfment and demands on conformity, because the compromise-possibilities are almost non-existent.

The essay deals with the understanding of the two key concepts from Sein und Zeit (SZ) mentioned in the headline, including a debate on the issue of das Man in Inquiry: an Interdisciplinary Journal of Philosophy. It is noted that reading SZ involves being simultaneously written by the work in a process of reciprocity; this entails a questioning of alleged possession of this or any work, it having been made accessible to the public by its publication.Das Man, as a concept for inauthenticity, needs a counterpart for authenticity, which in SZ is provided by Eigentlichkeit, Self-ownership.This comes into existence via ?being-towards-death?, where the caring being, as a being of possibilities, encounters its ultimate possibility death which is also the end of possibilities.The Inquiry debate, the main contenders of which were Hubert Dreyfus and Frederick Olafson, hinges on the question whether das Man should be understood primarily as ?at bottom a deformation of Mitsein? (Olafson) or ?the conformity necessary for the institution of collectively intelligible social practices (Dreyfus, in the words of his advocate in the debate, Taylor Carman). Both sides, however, give evidence of misreadings of SZ of a kind that call for an explanation. The proposal is that this could be given in an analysis of such a rhetoric of polemics that transforms SZ into a state of Vorhandenheit when making it an object of investigation by the contenders rather than such a tool for being-changed that is mentioned above.The relation between the two aspects of das Man, as oppressive know-all or as forms of established truth for Dasein, remains unsolved, however.

One of the city of Stockholm?s main objectives is to have a society completely free from fossil fuels. To achieve this, several investments regarding improvements in energy efficiency and renewable energy are currently being planned or implemented. One of these investments is a project called Hallbara Jarva which is located in the suburbs of Stockholm. The purpose of this thesis is to examine the prospects of an investment in photovoltaic cells from an energy-saving and economical point of view. The analysis is limited to three buildings within Hallbara Jarva and is intended for the property owner.  Solar energy is a type of renewable energy source and is commonly divided into solar heating and solar power.

This report consists of a discussion about suitable methods for studying complex sociotechnical systems that are still being developed. There are large economical advantages with studying new systems before they are completely developed since problems can be discovered early and thereby avoided. It is, however, difficult to study developing systems, there are methodological limitations. These limitations are discussed and recommendations for studying non-existing complex sociotechnical systems are presented.The report is based on experiences from a study of the introduction of a shipboard helicopter on the corvettes that the Swedish Armed Forces are developing. A shipboard helicopter implies high requirements on the hosting ship.

My master?s thesis is a study of acquisition of photographies during 1958-2008. The questions I proceed from is what patterns lies behind the Royal library's acquisition of photography and how the process of acquisition looks like. The theoretical base which I lean on consists partly of a problematization of the process of cultural heritage and partly of organizational theory. The problematization of the process of cultural heritage is my foundation of this essay.

There is an increase of financial integration, which can be seen in recent mergers of banks, financial institutions etc. in the European Union especially in the Nordic countries. However there are some weaknesses in providing consumers cross border services in the sector of banking, such as cross border bank account transfer of payments. The existing transaction costs do not encourage cross border services. Nevertheless a customer of a global or European bank can anticipate to be treated the same way in all of its branch offices inside the EU countries.
