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.

Slöseri är ett stort problem på byggarbetsplatser. Ett koncept där minimering av slöseri ärcentralt är Lean-manufacturing. Detta arbetes syfte var att utreda hur förbättringsarbeteanvänds på byggarbetsplatser. De befintliga systemen för förbättringar analyserades ochförslag till förbättringar gavs.Genom intervjuer undersöktes hur förbättringsarbete sker på byggarbetsplatser.Egenkontroller och arbetsberedningar användes som kvalitetsarbete på arbetsplatserna. Detvisade sig att de inte har något system för förbättringsarbete.

Shopping for groceries often means that, as consumers, we travel to the grocery store ourselves, by ear, bike or on foot. At the store we pick out the groceries that we want, go the register and pay for them. During the last couple of years consumers in Sweden have been given the opportunity to let someone else select and transport the groceries to their home instead, so called home shopping. As this report is being written, the possibility to buy groceries this way is somewhat limited, but many forecasters believe that in the near future it will increase immensely. Because of the large volumes of groceries that are being transported, there is great transport work being done in the supply chain.

The question of excessive global energy use needs to be solved. All energy production and usage have negative environmental impacts, which are best solved by reducing energy consumption and by using energy more efficiently. A large part of the Swedish energy use is concentrated to the building sector and to reduce the total energy consumption real efforts need to be made to make buildings more energy efficient.The aim of this study was to investigate how energy is used in one of Göteborg University?s buildings and to find measures that can be taken to improve its energy efficiency. The chosen building Zoologen, is used for research and education.The main method of the study is computer simulations of the present building and of possible energy reducing measures to be made in the future.

Byggbranschen är, jämför med andra branscher konservativ. Förändringar, förbättringar och effektivisering sker men inte i den utsträckning och takt det borde. Under mitten av 1980-talet utvecklades en ny samarbetsform i USA och Storbritannien, som kom att kallas för Partnering.Vårt huvudsyfte med denna rapport är att se hur tillämpning av samarbetsformen partnering är inom småhusprojekt. Partnering är ett begrepp som används där man har gemensamma mål, öppenhet med öppna böcker och stor tillit för byggherrens bästa. Att försöka definiera partnering i Sverige har inte varit angeläget eftersom stora variationer i arbetssätt gjorts till respektive projekt.

Lean produktion är en filosofi vars förenklade syfte är att producera mer produkter och samtidigt använda färre resurser genom att eliminera slöseri i systemet. I grunden är det företag som ägnar sig åt stycktillverkningen som anammat tekniker inom lean men på senare tid har denna filosofi spridit sig även till andra branscher. Utvecklingen av lean mot processindustrin har däremot gått mycket långsammare vilket medför att den industrin fortfarande har mycket att lära när det kommer till lean. En del kritiker menar att möjligheten att använda leantekniker i processindustrin är väldigt begränsad medan andra hävdar att det bara krävs ett annorlunda angreppssätt och att de olika metoderna måste anpassas efter processindustrins förutsättningar.Då lean syftar till att eliminera olika typer av slöseri ur systemet finns det en generellt vedertagen metod som heter värdeflödesanalys. Denna metod används för att kartlägga material- och informationsflödet för att man på så vis ska kunna identifiera slöseri som existerar i systemet.

Det var under 80-talet Lean satte sitt namn på den organisatoriska kartan. Lean är ett arbetssätt vars syfte är att effektivisera produktionssystem och eliminera moment i arbetsprocessen där ett direkt värde saknas. Allt fler organisationer väljer att implementera Lean trots att det finns kritiker vilka liknar arbetssättet med Taylorism och Scientific management varför vi finner ämnet intressant. För några år sedan var en av författarna bakom den här studien med och implementerade Lean på sin arbetsplats. Uppfattningen författaren fick var att medarbetarnas mottagande av Lean var negativt, ur det negativa mottagandet föddes en nyfikenhet hos författaren över relationen mellan Lean och medarbetaren.

This study is a quantitative study designed to examine whether training in health issues may have contributed to the increase in head managers' psychological capital (PsyCap). Construction consists of the following components: self confidence, hope, optimism and resilience. A high PsyCap considered beneficial in organizational change and steer towards the positive development and helps individuals in stressful situations. The results show an increase of characteristics such as hope and optimism among managers (N = 15) who have undergone training in health issues compared with managers who have not undergone training. However, the tests show no significant difference in head managers' attitudes to health breaks, not the severity of granting health breaks in the groups as a result of training.

With increasing wine consumption and a growing assortment at available to Swedish consumers, there is an interest in understanding the decision making process of Swedish wine consumers. In this thesis the expert phenomenon is studied with respect to wine through wine critic reliability: grading objectivity, understanding the process of wine criticism and possible critic influence on consumer behavior. Two studies were performed; a qualitative in-depth session of interviews with industry connoisseurs and a quantitative analysis of 589 online wine reviews. Our results indicate that wine reviews are highly subjective and defy prediction through analysis of external variables. Critics are likely to judge differently based on what information they have at hand, suggesting that expectations affect grading.

In this paper the authors aim to examine the effects on consumers using different strategies in a campaign within social marketing. A model by Evans et al (1996) has been used in order to see the different steps in which advertising catches the viewers? attention and eventually leads to action or purchasing. However, in the case of this thesis, the intention of the chosen campaign is to change the consumers? attitudes and behavior towards alcohol.

The purpose of this Master?s thesis is to examine the portrayals of class in four Swedish contemporary novels that have been mentioned as working class literature in the literary public sphere. During the 20th century, society has undergone vast changes due to globalization and technology development. The rise in standards of living for most people in the Western societies has led to changed consumption patterns. In consequence, there has been increased emphasis given to cultural rather than materialist explanations of social stratification.

In this study I have compared two systems of handling TMR, self-propelled/ self loading mixers and conventional towed mixers, what has been investigated is the time for filling, mixing and feeding TMR as well as maintenance and fuel consumption. The background of this study is the structural rationalization within the Swedish milk production that has put focus on efficiency and reducing of costs. Forage and labour are the two biggest costs in milk production today. The study has been performed by visiting three farms and with a stopwatch measured the times for filling, mixing and feeding TMR. At the time for the visits, the users have been interviewed regarding maintenance and fuel consumption. They have also had an opportunity to give comments of how they experience the mixers. The result of the study after processing is that the average stock in the study can save 74000 SEK a year by reducing time for filling, mixing and feeding TMR to cows with a self propelled/ self loading mixer . The conclusion I can make of this study is that it?s not the size of the stock that decides whether it?s interesting to invest in a self propelled/ self loading mixer, but the presumptions on the farms, for instance forage logistics and mechanical equipment..

Roughly 130 000 dwellings have been officially registered since Norway as of summer 2009 passed their bill ?Energimerkeforskriften? on energy performance certificates in buildings. The main objective is to decrease the total amount of national energy consumption by producing a methodology of calculation of the integrated energy performance of buildings as well as proposing cost effective measures to lower each building?s energy consumption. As the measures should not contravene nor be incompatible with the intended quality and character of the building, the ?Energimerkeforskriften? exempts buildings that due to their historical and cultural values are protected cultural heritage legislation. The current system offers a couple of professional certification alternatives, but when two online semi-automatic methods developed specifically for non-professionals are by far the most used, and since the methods of calculation primarily have focused on modern building materials and construction, the rest of the historical building stock stands literally unprotected by incorrect performance certificates and high-risk energy efficient measures. The objective of this thesis is to identify if the current Norwegian energy certificate system poses a threat to older buildings.
