Ground construction has to a large extent been dominated by traditional meth-ods during the last 50 years. Although the construction has been changed meanwhile innovations are not accepted. In collaboration with NCC Ltd Region South, I have examined a modern con-struction methodology that has been developed by NCC for future large pro-jects. The method is divided into two central phases. Phase 1 is? Single Pro-duction? which is a preliminary period for ground constructions to come.

As a consequence of increasing wind power installations in the Nordic grid the last years, the need for regulating power has become larger. In the Nordic grid, regulating power is mainly provided by hydro power. One part of the regulating power is called frequency control, which ensures that the grid frequency is stable and close to 50 Hz.However, setting the turbine into frequency controlled operation may cause stress and wear of the components in the mechanical control system. Frequency controlling implies large and frequent servo forces and longer travelling distance of the sliding bearings in the Kaplan turbine.Based on one selected Kaplan turbine, Selsfors G1, measurements and MATLAB calculations have been performed in order to determine forces and movements of the linkage system. With these forces and movements as input, stresses and fatigue have been determined as well as sliding distances, bearing pressures and wear of bearings during a typical lifetime of 40 years.The results indicate that no severe wear exists on the bearings during 40 years of service.

Previous research has discussed how voluntary disclosure relates to the cost of equity capital. Theories of estimation risk support a negative association between disclosure and cost of equity capital, as empirically documented by Botosan (1997) among others. In this Bachelor thesis we investigate whether such a relationship exists on the Swedish capital market. Using the CAPM to estimate the cost of equity capital and a disclosure index based on Aktiespararen?s annual evaluation of corporate disclosure, we test a model where disclosure explains cost of equity capital.

I denna studie behandlas effort shapes kopplat till digital animation med syfte att undersöka om det finns en könsbaserad skillnad i uppfattning och bedömning av karaktärsdrag. De animationer som har producerats är grundade på effort shapes som härstammar från Laban Movement Analysis. Metoden som har tillämpats för att samla in data är en kvalitativ enkät med öppna frågor som har besvarats av tio män samt tio kvinnor. Resultatet visade att det finns en skillnad mellan könen i bedömningen av karaktärerna men inte i uppfattningen av karaktärsdragen..

The aim of this work was to study if the edge of the forest is more resistant to heavy winds than the trees located further in from the edge, and how this edge effect changes between different types of tree species and site types. The data was collected from an electric power line going from the north to the south of Sweden. The mean value of the clearcutted area around the power line was 120 meters. The main direction of the storm in January 2005 was west-southwest and thus the power line was a perfect place for gathering a large data set. The main parameter studied was the damage frequency at the edge of the forest compared to the trees located further in from the edge (up to 100 m from the power line). Tree species mixture, soil moisture class, soil type, topography, stand height, stand height of the stand on the other side of the power line and wind exposition was estimated. The results showed a distinct edge effect. The edge of the forest had clearly lower damage frequency for all tree species. A marked difference was observed between tree species and damage frequency.

The aim of this study was to, using previously collected data from self-declared antisocial behaviour questionnaires, examine if the crime frequency has been different between adolescents that have either been referred to two different forms of open care in social service, child and youth psychiatric inpatient care or have been sent to Homes for Specialised Supervision. The criminality frequency and the most common crimes committed were compared between the study groups and further between genders in each particular study group. Statistical significance testing was used and the results of the survey revealed that juvenile delinquents that had committed severe criminal acts were represented in all four groups. The study group with adolescents in national care was the most different from other groups. These youths seemed to have had a lower crime frequency than the other groups with the exception assault and robbery.

The aim of this Masters thesis is to examine the library discourses concerning the phenomenon and concept of digital libraries in Swedish library press 1980-2002. What changes can be identified? The questions are: what is said about the conditions for the phenomenon; how is the concept of digital libraries used; who makes these statements; what are the relations between these discussions and the library context in which they are made? Five Swedish library journals, BBL/Biblioteksbladet, DIK-forum, Human IT, Svensk biblioteksforskning and Tidskrift för dokumentation, were examined. The method used was discourse analysis. The theoretical starting-point was Foucaults discourse theory.

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.

Syftet med denna uppsats är att bidra med ökade kunskaper om och bättre förstå hur fyra lärare använder och förhåller sig till digitala verktyg och digital teknik i undervisningen i svenska för senare år. Studien har en hermeneutisk fenomenologisk ansats och baseras på semistrukturerade kvalitativa intervjuer med informanter som har olika ämneskombinationer. Informanterna i studien har en jämn könsfördelning, är av olika åldrar och har varierande antal tjänsteår. Tematiseringsarbete som mynnade ut i fyra teman kan sägas karaktärisera lärarnas upplevelser av att använda digitala verktyg och digital teknik i undervisningen. Teman som växte fram och även utgör rubriker i resultatavsnittet var den utåtriktade tekniken, den betydelsefulla direktheten, den kontextförstärkande digitala tekniken och den svårkontrollerade användningen.

The purpose of this paper is to analyze and map out the cyber culture of the Internet and its all users, identity, design theories and services. How people communicate and how they build up their identities are some of the baselines. I will also discuss the important aspects of Interaction design and how this can be used in a Community for digital storytelling. The Internet, or new media, was founded in the 60?s by some great philosophers (McLuhan, Rheingold, Lambert and more). With influence from their books I will discuss and analyze what kind of media the Internet is and how it can be seen as extensions to our senses, as McLuhan claims.

The purpose of this qualitative thesis is to describe and analyse the implementation of an education system in the newly independent state, Timor Leste. One question to be discussed is whether an emergency phase is still going on in the development of a functioning school system, or if Timor Leste already reached a capacity building phase? Via the participant's answers in field observations and interviews, the study analyses the clashes between generations, social classes and different levels in relation to the choice of Portuguese as an official language and the international environment in the country. The thesis concludes that a lot of work remains in creating a fully functioning education system. We enjoyed the writing - and hope you will enjoy the reading!.

The purpose of this thesis was to examine if users of digital music games may acquire skills from the games that may be of use in learning to play a real instrument, that is a non-digitally simulated instrument like an acoustic piano. We have used Gee?s theory regarding a possible interconnection between different semiotic domains, and how this connection may enable a transfer of skills between related domains. In this thesis we examine possible skill transfer between the domains ?digital games? and ?non-digital instruments?. To examine our question formulation we chose to conduct a pilot study from which we collected both quantitative and qualitative data.

This paper describes a method for wireless energy transfer via near-field electromagnetic inductionthat is inexpensive, simple and can be applied to almost any type of system, regardless of size andenergy demands.The method uses a primary unit consisting of an oscillator, amplifier and inductive coil thattransfers energy to a secondary unit consisting of a coil, rectifier and voltage regulator. Two typesof oscillators and several amplifier designs were realized and evaluated together with a multitudeof flat coils of both monofilar and bifilar type.The results show that it is important to use an oscillator whose frequency is dependent on theinductance of the connected transmission coil, such as the Colpitts oscillator. This is preferable toan oscillator with a preset frequency, such as a Schmitt-trigger oscillator..
