Svenska Kraftnät is (together with the other transmission system operators of the Nordic power system) responsible for keeping balance between the generated and demanded power in the Nordic power system. Spontaneous load variations and system disturbances, however, lead to power imbalance followed by frequency variations. The frequency deviations can be limited to an acceptable level by the spinning reserve, mainly by hydro power control. But there are also other system properties which have a great influence on the frequency and system stability. The frequency and voltage dependence of the loads have a direct influence on the power balance.

Safe in the cityscape? Gender aspects on spatial city planning In this thesis, theories regarding gender and spatial planning are applied to the comprehensive plan Fortuna och Hemgården in eastern Malmö. Independent of factors like class, ethnicity and age women experience lack of safety to a larger extent than men do. Today, safety aspects on housing projects is scarcely a controversial issue, quite the contrary. However seldom are the central terms such as safety and security defined. Research has shown that women feel safe when they experience little risk of being subjected to violence; security is deeply interconnected with feeling safe.

Syfte: Syftet med denna uppsats är att genomföra en deskriptiv studie och skapa djupare förståelse för hur svenska, nyligen börsnoterade medicinteknikföretag arbetar med Investor relations och hur detta arbete återspeglas i en effektiv aktiemarknad. Samt att undersöka hur de utvärderar effekterna av sin IR-verksamhet.Metod: Genom en kvalitativ studie söker denna uppsats svar i intervjuer med börsnoterade medicintekniska företag, samt i teorier som behandlat möjligheten för rationella investeringar och utformningen av en effektiv marknad.Resultat: Den kapitalkrävande bransch som medicinsk teknik utgör har troligen påverkan på hur kommunikationen och informationsspridningen är utformad då alla respondenterna använder Investor Relations på liknande sätt. Företagen själva anser att det företag som lyckas övertyga investerare om att deras produkter har störst samhällsnytta även kommer att vinna kampen om kapitalet. Trots hård konkurrens om kapital och förståelsen över vikten av Investor Relations görs inga omfattande utvärderingar av arbetet. Anledningen är främst att det tar för mycket tid och att tillvägagångssätten är diffusa.

The purpose with the essay is to illuminate four former clients? personal stories about the meeting with the authority in the Swedish welfare system and the institutionalization theywent through. The questions being asked in the essay focus on communication, the relationship concerning power and the former clients attitude towards the institutionalization as a treatment. Four interviews were held with former clients who were institutionalized sometime between the ages of 15-25. The results were then analyzed by theories focusing on communication as a way to gain power and how social interaction may influence the individual attitudes towards authorities.

How effective is consumer power? Can consumers regulate corporate behavior?And if so is the case, could the mechanisms where consumers regulate corporatebehavior have any democratic value to contribute with? These are the questionsthat this master's thesis comprehends with. The purpose of this writing is toconstruct a theory of consumer power that is compatible with democratic theory,this in order to contribute to the ongoing discussion within the discipline ofpolitical science about the third democratic transformation. A discussion that hasbeen actualized due to the democratic deficit created by the growing corporatepower and the shift of power from state to private enterprises. Besides showingfor a parallel between the democratic mechanisms that exists in the relationbetween citizens and state on the one hand, and the consumers and corporationson the other hand, this paper argues that consumers do have a great potential inregulating corporate behavior towards a higher social responsibility andawareness.

Investor Relations is a function used by companies to compete for capital by creating relations with investors. It is a young function, earlier practiced by the same people who had responsible for exercising the Public Relations.Investor Relations has evolved a great deal lately but there are still no concrete theories behind the function. The aim though is clear and there are literature explaining how to practice the different parts. The most research within Investor Relations uses the theory of Relationship Marketing. Lately the two authors Hägg and Preiholt have started to examine what they call Financial Marketing since Investor Relations is about relations between actors on financial markets primarily.In this paper, we examine the aspect of information in Investor Relations.

In today?s Europe, migration has become a security issue rather than a humanitarian issue. Previous research highlights how migrants have become prisoners of bureaucracy in Europe by their mobility being hindered. The present study critically analyses the migration governance in Europe by highlighting labour market integration in Sweden. The study highlights migrants with a specific focus on foreign-born women. The research questions chosen to examine this phenomenon is: How does migration governance in Europe affect member states' policies for labour market integration, with a particular focus on Sweden? How do foreign-born women in Sweden experience labour market integration processes within the framework of the governance mechanisms that exist in Europe? Foucault?s theory of power and the theoretical concept of choking composes a theoretical framework which is used to analyse focus group data and text analysis data.

Wind power is becoming an increasingly important source of energy. There are several national and international goals set to increase to amount of renewable energy, and in order to meet these goals, the wind power production plays an important part and the establishment of new wind power farms are required. The Swedish national project Riksintresse Vindbruk has appointed areas in Sweden suitable for wind power, mainly when looking at the physical wind conditions of the area. In this study, I aim to define suitable areas for wind power establishment in Norrbottens län. In order to reach this goal, a critical regional method was developed and completed using GIS.

AbstractThe development of new economies from the industrial revolution to the information society of today has led to an increase in goods, services and information technology. It has also affected the way that organizations are formed and shown that organizations transform more and more into networks. This has left an impact on the concept of marketing and an increase in the handling of internal relations within companies. The marketing concept has developed from the 4P:s, price, place, product and promotion, to relations marketing as a new perspective.This study focuses on a description of relations marketing in medium - sized advertising agencies. The advertising business has a long history of close customer relations and advertising agencies strongly depend on new customers.

AbstractThis paper is a comparative study of the final reports of the Norwegian and Danish power studies performed in 2003. While the Danish study found that democracy is thriving, the conclusion of the Norwegian power study was that democracy is in a crisis. The purpose of this paper is to find explanations to why the studies in two Nordic countries arrived at such different results.Methodologically, the paper consists of an ideological text analysis and critical analyses of the discourse. In order to study how the results of the power studies can differ so considerably, the following aspects have been surveyed; 1) external contexts (government inquiries); 2) work process (the researchers? background, role and co-operation); 3) the problem areas and themes studied; and 4) power perspectives.

The assignment given to us by NCC was to compose a degree project based on ground excavations for power cables. The aim of the study was to examine suitable excavation methods depending on different possible terrain conditions. The amount of previously written material within this subject is nearly non- existent and therefore there is a genuine interest by the NCC to receive a compilation of different production methods. The greater part of this study is based upon interviews with several companies active within this area of expertise. The technique of placing the electricity grid beneath ground for safety is today getting more and more common.

This master thesis describes the development of an UPS module. UPS is an acronym for Uninterruptable Power Supply. The UPS module has been developed at the company AerotechTelub AB. The UPS module delivers the necessary voltage and current in case of a power interrupt. If a power interrupt occur, the computer system has one to three minutes available to store data and shut down correctly.

The aim of this study is to increase the understanding of the causes of the first war between Russia and Chechnya. Empirical data consists of four half-structured interviews with former Russian and Chechen war participants that tell about their perspective of the causes of the war between Russia and Chechnya. The study used narrative method and the theoretical framework consists of International Relations theories such as Realism, Geopolitics, Liberalism and Marxism. Geopolitics sees the geostrategic interest, territory as a cause of war. According to realism warfare occurs because of the state?s endeavor after power and influence in term of territory.

The scope of this project is to make a comparison of costs associated with wind and nuclear power in order to decide which one of these is the most suitable in the case of an increased demand for electricity. It is also investigated if there are other factors that can influence the choice of energy source.An average cost is calculated in terms of kronor per kilowatt-hour (SEK/kWh) using cost of investment, operation & maintenance and taxes & subsidies. Total investment cost is recalculated to production cost using the annuity method at three different interest rates (6%, 9% and 12%).The comparison is made between three cases of wind power and two cases of nuclear power. For wind power there are two ocean-based (300MW and 100MW installed capacity, respectively) and one land-based (60MW) wind farm. For nuclear power there is one EPR-reactor (1600MW) and one AP1000-reactor (1100MW).

The purpose of this project was to study how the interference between two antennas in a MIMO system affects the linearity of the power amplifiers powering the antennas. For the MIMO system, two power amplifiers and twoantennas were constructed and designed using the software ADS and a software defined radio was constructed using the platform USRP and the software LabVIEW. The result was that the interference between the antennas affectsthe linearity of the power amplifiers powering the antennas adversely and a reasonable theory was that the interaction decreases inversely proportional tothe square of the distance..
