Kraftkabelförläggning i mark : - en studie av produktionsmetoder
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.
Konstruktion av UPS-modul
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.
Vindkraft eller kärnkraft - En jämförelse
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).
Framtidens mobilnät
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..
Är det lönsamt att ta hänsyn till temperatursvängningar? : En fallstudie om prognostisering på Karlstads Energi
Being able to predict the future had been an invaluable competitive advantage for any corporation. Forecasting is a vital part of any business, hence a good forecast allows enterprises to invest in a beneficial way. However, there are several ways to prepare forecasts and the forecast methodology can vary. An industry that is dependent on forecasts is the energy industry. By predicting consumers' energy consumption, Swedish energy companies can hedge on the Nordic power market Nord Pool.
Swedish SME Financing - Evidence from the Game Industry
The objective of this thesis is to examine the capital structure of Swedish small and medium sized enterprises (SMEs). Accounting data from Swedish game developers, combined with the result from a survey, is used to examine their financial conditions and capital structure decisions. We find that non-debt tax shield, firm size, growth opportunities and age are, to various extents, the determinants of capital structure in the game industry, while effective tax rate and asset structure have marginal effects. Our study also implicates that most of the existing capital structure theories can explain SMEs leverage decisions to some extent; however, some adaptation is needed to fit these theories into the SME context. Additionally, we find the existence of a financial gap in the game industry which might need efforts from both demand side and supply side to eliminate..
Reducering av effektförbrukning i inbyggda system med Linux
Linux is a growing operating system in embedded systems. Today, Linux is not only in heavy servers but also in cell phones, PDAs, cameras and other devices running on battery power. While current technology is more energy efficient, more and more technologies are implemented into a single unit resulting in an overall increase of power consumption.Low power consumption is an increasingly important feature of a system today. Lower power consumption means lower costs, less environmental impact, and longer life for applications that runs on batteries.This work compiles methods to reduce power consumption of Linux systems. The work includes examining whether the available opportunities are platform-specific or of a more general nature.
Att börja från noll. En studie i storstadssatsningens försök att öka det politiska deltagandet hos Malmös invandrare
This thesis title starting from zero alludes to storstadssatsningen's democratic work being accomplished among immigrants in Malmö. My thesis examines which types of political participation storstadssatsningen were trying to increase. The goal was to turn the immigrants into political participants, but in many of the projects the democratic work had to focus on building a ground for democratic participation by bringing isolation to an end and teaching the Swedish language. This may have been the reason that there were not extensive forms of resources to put into projects actually raising the political awareness. Some of the projects can however be said to increase a very large number of types of political participation, both temporary and every day participation.
Riskmodell för kabelsträckningar i mellanspänningsnätet i Sverige
The society of today is largely dependent on electricity and the dependence does not show any signs of declining. Reliability of supply will become increasingly important in the future and it is therefore important to investigate factors affecting the failure rates in electrical components.Sweden was hit by several severe storms during the 00?s. As a result of this many overhead lines in forests were cablified. In urban areas underground cable systems have been the norm for many years.

Captureteorin : Regleringar och konsten att fånga politiska beslut i den demokratiska processen tillämpad på den svenska läkemedelsmarknaden
The Capturetheory wants to give an alternative explanation for the need of regulation. From this point if view the government does not have enough information to make an optimal regulation. There is a possibility for different interest groups to take advantage of the political arena by rent- seeking behaviour. An industry may be willing to be regulated to protect itself from competition. The objective of this paper is to account for the pros and cons of the theory of regulatory capture and also if it can be applied to the Swedish market of pharmaceuticals.
Underh?llande propaganda? Hur popul?rkultur framst?ller USA:s makt i en tid av dess f?r?ndring
Popular Culture is inherently political and the connection between popular culture and world politics in particular is something that has been established through years of research by multiple scholars. In this essay, my aim is to analyze how American Power is represented in popular culture. This is done in context of the decline of the American led liberal hegemony and a new Multiplex world order. A world order with multiple influential actors with varying levels of power. To analyze the way popular culture portrays American power, I have used the movie Top Gun: Maverick (2022) as an example and analyzed scenes from the movie.
Stress i byggbranschen : Orsak till stress i byggbranschen samt förslag på åtgärder
Stress and burnout are two words that are commonly occurring in many contexts today. More and more people experience that they are stressed and that they does not feel well. The long term sick -leave increases as a consequence of people being burned out. These phenomena prolong over all ages, sexes, classes and professional categories, which probably means that the construction industry would not be spared. In the construction industry, stress and bad health are no new phenomenon, already during the 1970s and big parts of the 1990 s, the construction sector were exposed to the phenomena.A sector that has a large turnover annually cannot presumably be faultless.

In the evaluation work, special effort has been made to develop designs that really stress the FPGA to find potential problems.
De mänskliga rättigheternas beskyddare
The Human Rights claim that all humans have special rights that are not allowed to be broken or violated. Although these rights are broken and violated by states every day. One major fact that makes this possible is the principle of sovereignty that includes all states, and which says that every state has the power and right to make decisions and create laws within the own country without the interference of other actors. In other words, the problem is that the states have to much power in relation to actors usch as the United Nations and to the rules of the Human Rights. This essay describe a possible way to strengthen the power of the Human Rights so that all humans can be guaranteed the fulfillment of the rights..
