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.

Avsikten med uppsatsen är att ta reda på om det skapats ett nytt radiolyssnarmönster i och med att Sveriges Radios (SR) erbjuder tjänsten on demandradio, det vill säga möjlighet att lyssna på radioprogram som redan har sänts på vanlig radio eller webbradio. John Fiske Kommunikations teorier har använts samt Walter Benjamin teorier som behandlar förändringar som sker vid reproduktion. Historiska teorier av Marshall McLuhan och Tony Schwartz har även använts.Författarnas metod består av tre delar där en jämförelse genomförts mellan olika sekundära data från SR, Radioundersökningar AB (RUAB), Nordiskt informationscenter för medie- och kommunikationsforskning (Nordicom), British Broadcasting Corporation (BBC) samt Radio Joint Audience Research Limited (RAJAR). Därefter har insamling av kvantitativa data gjorts via enkät som publicerats på SR:s hemsida samt via utskick till en referensgrupp. Författarna har gjort längre telefonintervjuer om cirka 35-45 minuter vilka spelats in och delvis transkriberats för att få in data med mer kvalitativ tyngd.

Denna uppsats ämnar redogöra olika för- och nackdelar med 4G ur ett användarperspektiv, där fokus ligger på smartphoneanvändare. Ett kvalitativt synsätt har tillämpats samt en blandning av deduktivt och induktivt synsätt, där det deduktiva synsättet är det övergripande. Primärdata består av intervjuer och enkätundersökningar. Sekundärdata består främst av akademiska, utvärderade journaler. Studiens syfte identifierades när vi tyckte oss finna en tydlig brist i kunskap bland användare om vad 4G faktiskt är.

I mitt examensarbete har jag valt att försöka undersöka i vilken utsträckning det i en hemmastudio är möjligt att återskapa ett sound från en professionell inspelningsstudio. Denna fråga är intressant för mig då jag fastnade för hur en produktion lät i ljudbilden. Dels instrumentuppsättningen och deras rytmisering men främst soundet på helheten i mixen. Det kändes luftigt, stort och brett i lyssningsspektrat trots att det inte var så mycket instrument. Jag har alltid velat utveckla min förmåga att skapa och producera musik men har inte tillgång till så mycket kvalitativ utrustning.

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.

Syfte: Vi vill ta reda pa? hur teknikutvecklingen relaterad till VoD pa?verkar beteendet hos unga vuxna och hur detta beteende fo?ra?ndrar tv-tittandet i denna ma?lgrupp.Teori: Denna studie anva?nder huvudsakligen tva? teorier fo?r att underso?ka problemet. Den fo?rsta teori som tas upp a?r Diffusion of innovation, Rogers (2003) som diskuterar innovationers spridning och pa?verkan i samha?llet. Fo?r att vidare underso?ka beteendet hos unga vuxna anva?nds Jakob Bjurs avhandling Transforming Audiences (2009) som underso?ker individualiseringens mo?nster inom tv-tittande.Metod: En kvalitativ empirisk fallstudie baserad pa? intervjuer av fokusgrupper samt personintervju.

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.

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.

I have done a follow up study of the restoration of two rivers, Röälven and Grundan, in order to evaluate the effects of the restoration on the endemic population of trout. Both rivers have been used for timber floating during many years throughout the 20th century, and because of this, had all obstacles such as rocks and wood parts removed. In 2004-2005 both rivers were restored, and rocks and wood were put back into the rivers. Spawning grounds were created and boulder dams were constructed to promote the streaming water. The result showed that the trout population of both rivers increased after the restoration, but also that the trout population of Röälven increased more than that of Grundan.

The energy sector is facing an impending paradigm shift. Today?s technology enables the end-user to generate their own energy locally at home. Furthermore, recently developed storage technologies make it possible to balance energy demand with stored energy and integrate district heating with the local power grid. This means that in the future heat and electric power will interact and energy flows is converted over energy boundaries.
