Mätning i nätstationer - nyttor och problem

The purpose of this study has been to investigate advantages and problems with distributionsystem metering in substations. This report is a study in cooperation with Göteborg Energi.The analyses in this report are made for GENAB, a subsidiary company of Göteborg Energi.To analyse advantages and problems in advance is interesting information for GENAB. Theresult of the report could be based upon whether installation of metering in distributionsubstations will be implemented and in that case which kind of measurement that is relevant.The most relevant and strategic place to implement measurement is at the distributionsubstations on the secondary side (400V), this is due to the placement of the currenttransformers. The measurements in this study involve current, voltage, power, power factor,temperature, energy and power quality.Measuring instruments that are relevant to implement are intended to measure current,voltage, power, power factor, energy and, possibly, power quality in the same measuring unit.It is desirable to have a measuring instrument that measures both energy and power qualitybut since it is most often a cost question, it can be established that energy meters have a lowercost.Metering in distribution substations gives a better illustration of the power network. Thisresults in many advantages for GENAB.

Attitudes towards hedging by diversified and non-diversified farmers : a comparative qualitative study

Deregulation on the market for agricultural products leads to a more globalised market with increasing price fluctuations. This, in turn, places the farmer in positions influenced by new risks but also improved opportunities. The farmers are faced by uncertainty in terms of financial outcome. To be able to utilise these new market conditions it becomes increasingly important for farmers to continuously follow the price trend, and to develop strategies how to manage the risks exposed by a volatile market. Farmers with different conditions perceive risk in different ways. Hence, their risk management behaviour will vary.

Optimal kapitalstruktur : En undersökning tillämpad på skandinaviska och tyska företag

This paper describes and develops a trade off model of optimal capital structure by Bradley et al. (1984). The model is then tested to examine how changes in corporate tax rates affect the optimal capital structure of firms. Based on theoretical implications of the model, four hypotheses are derived stating that firms? optimal debt-to-value ratio is (1) negatively related to financial distress costs, (2) negatively related to non-debt tax shields, (3) negatively related to firm volatility and (4) positively related to the corporate tax rate.

Miljö- och Handelsgåtan : Intellektuella egendomsrätter och dess implikationer i en globaliserad verklighet

This paper seeks to discern the political factors that determine the results of negotiations in international cooperation. On the one hand, it makes a contribution to the broader theoretical debate on international regimes by combining regime theory and theories on globalisation into an integrated framework for the analysis of international policy results, or in this case treaties (theoretical objective). More generally, globalisation theory will help us understand why it has become important to initiate international cooperation, and regime theory to elucidate how these international cooperations emerge. To many observers, it is the large transnational corporations of the rich North, which have done best out of free trade. Through the huge influence they wield over governments at the WTO (World Trade Organisation), these corporations have won the freedom to move around the globe without restriction, making use of cheap labour, and locating wherever they can best tap into the largest and most lucrative markets.

Bonusar : Mot ett långsiktigt tänkande

Background: The background explains different financial crises and the effect those crises had on the Swedish acquits regarding variable compensation. The resent discussion regarding variable compensation and the main problems with bonuses is also explained. Our theories for this essay is mainly based on the new directions from Finansinspektionen FFFS 2009:6,7 and stakeholder theory. Other theories used are agency theory, stewardship theory and economic man.Purpose: The purpose of this essay is to analyze the new directions for variable compensation and to investigate if these new directions can lead to a more long-term thinking for managers in banks. Method: We used semi-structured interviews with open questions for our survey.

Mest och minst kommenterat : vad skapar motivation att kommentera ett blogginlägg

Denna uppsats undersöker varför vissa blogginlägg får många kommentarer jämfört med mindre kommenterade blogginlägg. Utgångspunkten är att undersöka en dagboksblogg skriven av en tonårig kvinna, då det finns förhållandevis lite forskning inom detta specifika område. Materialet som ligger till grund för undersökningen är en blogg som heter Kenza och de tre mest respektive minst kommenterade inläggen från denna blogg under perioder från 1 januari till 28 februari 2009.William Labovs teori om narrativer och Wolfgang Isers reception theory utgör uppsatsens teorier. Metoderna som används är läsbarhetsindex, nominalkvot, narrativ analys och interpersonell analys.Resultaten som framkommit ur analyserna visar att i jämförelse mellan de minst och de mest kommenterade blogginläggen har de mest kommenterade få långa ord och en utpräglad verbal stil. Blogginlägg med en tydlig narrativ struktur och ett direkt tilltal fick också fler kommentarer. .

En systemlösning för en framtida fjärrvärmeutbyggnad i Täby : ur Fortum Värmes perspektiv

At the moment in central Täby there are small district heating network operated by Fortum Heat. The distribution network has an annual heat demand of about 70 GWh, which is supported by the network's two plants, Galten and Farmen. Täby as a region is rapidly growing and there are grand plans to develop the area. Estimated market potential for a future district heating expansion in Täby is very high and as early as in 2007 Täby decided to invest in a large-scale expansion. In autumn 2009 Täby did a procurement process, known as the ?Täby initiative?, to find a partner that could implement those expansion plans. To secure a cheap basic production the partner also need to build a power plant at Hagby recycling center. Despite high interest during initial state of the process, only one procurement offer were received and Täby suspended the contract in March the following year.

Vildsvinsskador inom jordbruket : hur stora är förlusterna?

Problems with wild boars are increasing in Sweden and some people argue that the wild boar population must decrease. This is mostly the opinion by farmers, while the hunters want more wild boars in Sweden. Today the population is the strongest in the south of Sweden and in the eastern parts of the country. However the population is growing stronger in other parts of Sweden as well. The population origins from these areas where they escaped from pens around 1970.

Kosovointerventionen ? illegal men legitim? : En fallstudie av NATO:s intervention i Kosovo med etiken i centrum

Trots lagar, nationella som internationella, återkommer diskussionen om etik vid militära interventioner. Uppsatsen handlar om huruvida NATO:s intervention i Kosovo levde upp till etiska lagar kring militära interventioner samt om normativa teorier fortfarande är relevanta och lämnas utrymme idag.Syftet med uppsatsen är att se om det fortfarande finns utrymme idag för normativa teorier, såsom den etiska teorin just war theory, och om dessa är rimliga att använda. Uppsatsen använder fallstudien Kosovo som exempel och analyserar samtidigt hur denna intervention lever upp till de nio punkterna i teorin.Kvalitativ textanalys samt fallstudie av Kosovo har använts som metoder och just war theory har använts som teori.Resultatet visar att sju av nio punkter helt eller till stor del levdes upp till under NATO:s intervention i Kosovo, och att de resterande två till viss del levdes upp till. Undersökningen påvisar också att normativa teorier lämnas utrymme idag, och att teorin fortfarande kan vara relevant, om än med lite modifikation..

Regler i förskolan : En studie om förskollärares och barns tankar

This thesis focus on the presentation of the filmic room the viewer sees in George A. Romero´s three horror classics Night, Dawn and Day of the Dead. The hypothesis goes as follow; fear and element of tension becomes greater if the audience/viewer has a good knowledge about the filmic room in the film, in other words, a good spatial awareness. The conclusion is that it does. The environment is active in its becoming and in its presentation to the viewer.

Att placera företagsinkubation i en Community of Practice - En studie om lärandemiljön i företagsinkubatorer

The role of small businesses is fundamentally important for the economic development in countries. Within this context, business incubation is used as an entrepreneurship development instrument to promote and support new firms in the early stage of their existence. However, research in the field tends to disregard the perspectives of incubatee entrepreneurs. The performed investigation is based on interviews with entrepreneurs from two different business incubators at Swedish universities. This study uses a Situated Learning Theory (SLT) as a theoretical framework, to examine the entrepreneur's experience of the learning environment in a business incubator.

Hållbar Ö ? en analys av möjligheterna att försörja ett modellösamhälle i Stilla Havet med solel

The goal of this paper is to provide a model for a sustainable electricity system to an island, in the Pacific Ocean near the equator.The method which has been used is to model supply and demand of electricity in the computer program Stella, through the creation of a dynamic system that balances them against each other. The result from the model will then be used to calculate the electricity price per kWh for the island.The result of the work is that electricity from solar energy is comparable with electricity produced from oil, if the oil pays for all its external costs, and the potential for pumped hydro storage plants is located. It also requires that consumers of electricity can be their own producers to avoid the expenditure of tax and reducing the cost of distribution. But since oil is a finite resource and has had a rising cost in recent years, while solar energy has had a declining cost, perhaps this will be a more competitive solution in the future.

Äldre invandrares kanaler för representation med fokus på föreningsliv

AbstractThe aim of this study was to highlight who represents elderly immigrants and apply the theory of social exclusion. We chose channels for representation that we found important in relation to this group. The first part is a study of available litterature of the subject. We found three main arenas: participation in elections, participation in associations and clubs and representation in political institutions. The findings showed a democratic deficit among elderly immigrants, which gave an indication of social exclusion from the political arena and from participation in associations.For the second part we decided to concentrate on the arena of participation in associations and clubs that represent the elderly and/or immigrants.
