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.

Questions about discipline have always been current within the Swedish school system, from the sixteenth century until today. The purpose of this study is to compare the discipline in two old-time elementary schools, located on Gotland, with each other.This study will compare an old-time elementary school from the countryside with an old-time elementary school from a town to show the differences in discipline between the coun-tryside and a town. This study will also focus on how questions about discipline changes from 1847 to 1937/1941. In order to do so I have studied the regulations from the two schools and compared them with each other. When I discuss discipline I will use Michel Foucault?s theory concerning the development of power and discipline in modern society.My study shows that it did not differ much in questions of discipline between the two ex-amined old-time elementary schools.

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.

Mitt syfte är att visa att känslan av trygghet spelar större roll för undervisningsklimatet i klassrummet än disciplin. Vi bombarderas dagligen i media från olika tyckare som har åsikter om hur skolan skall skötas för att den ska bli bättre och hur misskött den är nu idag. Det är nästintill omöjligt att sålla i det stora informationsflödet och avgöra vad som är relevant för att ge eleverna bästa möjliga inlärningsklimat i skolan. Kan det vara så att en skola som ger eleverna en känsla av trygghet är den som ger bästa inlärningsklimatet? Genom att besöka några klassrum, studera hur lektionerna fungerade i verkligheten och sedan intervjua de berörda lärarna om deras syn på trygghet i klassrummet, fick jag bekräftelse på att så kunde vara fallet.

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..

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.

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.

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.

Abstract Arbetet, som är skrivet av Martina Filling och Therese Rasmusson, handlar om synen på lärarens förändrade fostransroll mellan 1946 och 1962. Titeln på arbetet är En förändrad lärarroll och syftet är att undersöka vilka olika perspektiv som existerade i diskussionen om lärarrollens fostransuppdrag mellan 1946 och 1962. För att uppnå ett resultat och dra en slutsats har två tidskrifter använts som källor, vilka publicerades under den tidsperiod undersökningen ämnar undersöka. Utvalda artiklar ur tidskrifterna granskades och sammanfördes till en textanalys. Materialet för textanalysen består av lärartidningarna Skola och samhälle och Svensk lärartidning.

Skolverket har kommit med en ny läroplan Lgr 11, med förhoppning om att ändra utvecklingen i de svenska skolorna, angående elevernas svaga kunskaper i matematik. Det har debatterats och skrivits mycket om just de svenska elevernas svagheter i matematik både nationellt och internationellt. Mitt syfte med detta arbetet har varit att undersöka lärarnas erfarenheter (deras empirier) genom åren. Genom deras synpunkter och de gällande läroplanerna under åren, har min tanke varit att fånga upp deras åsikter om utveckling i matematik och varför det har gått åt detta håll. Besitter lärarna med kunskaper som är intressanta för vidare undersökning? Undersökningen har gjorts med en enkät, samt med möjlighet för lärarna att skriva egna kommentarer.

A new FPGA suitable for space applications has just reached the market. To investigate whether there are any possible flaws or limitations similar to those previously seen on FPGAs, an evaluation has to be done. This master thesis contains the evaluation of this new radhard FPGA with focus on possible design limitations and package related electrical phenomena.Areas evaluated: Ground-/VDD bounce, Cross talk, Rise time sensitivit, Power cycling, Power consumption, Place and route tool, Radiation hardnessThis report contains all steps in the evaluation. From method to measurements, comparisons, theory, results and conclusions. In the evaluation work, special effort has been made to develop designs that really stress the FPGA to find potential problems.

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..

During the last years commercial Wind Power Turbines (WPT) has become larger regardingto the generator sizes and hub heights. Available hub heights around 100 meters is nowcommon, which has led to profitability for WPT located in forests where there normally are tolow wind speeds. The current knowledgement regarding turbulence and the variation in thewind profile for the outcome of the power production for the WPT in forests is limited.In this Master of Science thesis an investigation concerning forest located wind power plantshas been made. The purpose has been to investigate if plants located in forest perform lesscompared to wind power turbines located at more common locations.The analyses are based on statically material for determining the availability,production/generator size, production/hub height, production/swept area and how thetopography affect the production results.The analyses show that the variation in production result for WPT located in forest comparedto turbines located at other locations is small. The availability is high and the productionresults are good..
