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..

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.

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.

Intervention med responsiva talakter inom AKK hos två deltagare med cerebral pares i Tanzania : en single subject design-studie

I många utvecklingsländer finns en begränsad tillgång på utvecklade AKK-system (Alant, 1999) och ofta även en okunskap kring möjligheterna att arbeta med kommunikationsproblem (Marshall, 1997). I föreliggande studie genomförs intervention i alternativ och kompletterande kommunikation (AKK) för två deltagare med cerebral pares på ett dagcenter i Kilimanjaroregionen, Tanzania. Syftet i föreliggande interventionsstudie är att genom intervention studera och utveckla de i mätsituationerna responsiva talakterna att påkalla uppmärksamhet för att inleda interaktion, acceptera och avfärda samt upprätthålla och avsluta interaktion. Detta sker med hjälp av begreppen ja och nej för att acceptera och avfärda, liksom mer och mindre för att upprätthålla och avsluta interaktion. Studien följer en single subjekt design och insatsen utgörs av två interventionsperioder, bestående av direkt intervention med deltagarna samt utbildning och fortlöpande handledning av personal.

Utvärdering av en FPGA för rymdbruk

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.

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.

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..

"Det krävs en by för att fostra ett barn" : En undersökning av sex- och samlevnadsundervisningen i mellanstadiet.

The purpose of this paper is to investigate how gender and sexuality are made in the videogames Prince of Persia and Fable II, and more specifically to look at possibilities and limitations for the construction of gender and sexuality in these games. I understand videogames as an interactive media form that differs from other types of media like film and literature. It is a media form that depends on a player to be played. At the same time it is constituted by rules of how it can be played. I have analyzed my material by a method called close-playing.

Utvärdering av svensk vindkraft : Skillnaden mellan skogs- och traditionella placeringar

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..

Interleukin-1s roll vid osteoarthrit hos häst

Osteoartrit är en progressiv sjukdom med inslag av låggradig inflammation som leder till degeneration av ledens alla strukturer. Många hästar drabbas och sjukdomen är en vanlig orsak till hältor vilket leder till stora problem, exempelvis förlorad träningstid, sämre prestation och i värsta fall avlivning. Osteoartrit drabbar synovialleder, som är uppbyggda av följande strukturer: ledkapsel, ledvätska, ledbrosk, subkondralt ben samt omkringliggande senor och ligament. Ledbrosket består av kondrocyter och extracellulärt matrix. I normalt ledbrosk sker lika stor nedbrytning som nybildning av de ingående matrixkomponenterna.

Vem får höras? : En undersökning av lokalpress kring makt och kön i fyra Landsortstidningar

2 (45)AbstractAuthors: Gunnel Forssell Ehrlich & Alexandra WinbergTitle: Gender in local press ? a quantitative study of four local newspapers Level: BA Thesis in Media and Communication StudiesLocation: Linnaeus UniversityLanguage: SwedishNumber of pages: 50The report shows a quantitative study of balance in gender and position of power in the local press. The study aimed to shed light on the distribution of space in the newspaper between men and women, those within power and those without in Swedish local press. The study was conducted with four newspapers, during a month of time with local editorial news material. In our study, we have assumed Lippmann?s and Strömbäck?s theories of pseudo-reality and distribution of gender and position of power in Sahlstrand and Jarlbro.
