Tidssynkroniserade mätningar i vattenkraftstationer

Vattenfall and Svenska Kraftnät perform start-up tests, where hydropower generators are used to power up the electrical grid in case of a blackout. To monitor the electrical grid, Phasor Measurement Units (PMU) are used. Each PMU is individually equipped with a GPS-receiver to precisely timestamp the data relative to the official time UTC. During the test, it is also of interest to timestamp the measurement signals from individual hydropower generators to later compare with PMU-data, and thus study the power grids impact on the generator. The aim is to work out an appropriate method to make these measurements and to build a data acquisition system, capable of timestamp data relative to UTC, from a generator in one of Vattenfalls hydroelectric power stations. The problem is that the generator is located in an underground station which hampers the reception of GPS-signals and wiring should be avoided if possible. Time synchronization has been solved by using Vattenfalls network, which is synchronized by the network protocol NTP.

Vad det nu hette...Jämställdhet...? : Ett utredningsarbete på en klinik

The aim of this investigation work " What was it called...Equality...? is to study a clinics current gender equailty plan from a gender approach and by a field survey see if, and in that case, how it can be improved. A connection between existing gender norms and gender power strukctures is applied in the results of this survey in order to illustrate their significance from an individual as well as a structural perspektive.The survey has been carried through by a field survey as well as a discourse analysis as method. Yvonne Hirdmans gender power system is on of the main theoretical points of departure.The results that I have achieved in this essay is that gender can be looked at in different ways within the labour market where women have the main responsibility over the family and are considered more nursing then men. Men on the other hand are thinking of their carriers and have higher salary requirements.

"Vi pratar aldrig om makt" - en studie om förskolepersonals föreställningar, intentioner och former för makt och motstånd i konstruktionen av det professionella subjektet

Sammanfattning Studiens syfte är att vidga förståelsen kring hur förskolepersonal konstruerar sitt professionella subjekt. Förskolepersonalens föreställningar om och intentioner i verksamheten visar på olika former för makt och motstånd i deras positionering som professionella. De centrala frågeställningarna för studien är: Vilka föreställningar, intentioner och former för makt och motstånd kan skönjas i förskolepersonalens samtal om förskolan och reflektioner kring egen praxis? Vad framträder som betydelsefulla delar i förskolepersonalens konstruktion av det professionella subjektet? Hur, i förhållande till dessa delar, positionerar sig deltagarna som professionella? Deltagarnas gemensamma samtal och enskilda reflektioner kring eget agerande står i fokus i studien. Förutom Foucaults teorier om makt används feministisk poststrukturalism i en strävan efter multipla förståelser av såväl subjektkonstruktionens processer som ställningstaganden och övervägande angående studiens utformning och innehåll. Intervjusamtal med respektive arbetslag och individuella reflektionssamtal utgör studiens empiriska material.

Energiewendes påverkan på det nordiska kraftsystemet

Both the German and the Nordic power markets are seeing dramatically changed conditions due to an ongoing process of expanding the share of renewable production in the systems. For the German part this comes from heavy subsidies which have led to an explosive development in installed capacity of photovoltaic and wind based production. After the Fukushima incident it has been decided to shut down all Germanys nuclear plants. This capacity drop is however not of the same magnitude as the increase in renewables, but will impact the stability of the power system. The Nordic power system which already has a surplus of power sees an even further increase, coming mainly from construction of new nuclear plants in Finland and a general increase in wind farms.

Purpose/Aim: To find power structures within the blog network.Material/Method: Using keywords to find all available blog posts about the National Defence Radio Establishment from the blog search engine Twingly, and thereafter using the same blog search engine to find inlinks from other blogs, to those posts. The data is set into the context of the small-world networks models of Duncan J. Watts and rich-club models of Sergi Valverde och Ricard V. Sole.Main results: 5183 unique blogs have written about the subject in 22779 blog posts to which 28128 inlinks from other blogposts are made.

A virtue is understood as a trait of character, manifested in habitual action, that it is good for person a to have. Virtues are interpreted as socially constructed. Empowerment is presented as a process toward self-confidence and self-determination where recourses and freedom propels the development toward power for the individual, the household and the community. Why does the concept of virtue deepen our understanding? It is argued that our theoretical perceptive of empowerment needs to better encompass values, norms and practise.

GPGPU : Bildbehandling på grafikkort

GPGPU is a collective term for research involving general computation on graphics cards. A modern graphics card typically provides more than ten times the computational power of an ordinary PC processor. This is a result of the high demands for speed and image quality in computer games.This thesis investigates the possibility of exploiting this computational power for image processing purposes. Three well known methods where implemented on a graphics card: FFT (Fast Fourier Transform), KLT (Kanade Lucas Tomasi point tracking) and the generation of scale pyramids. All algorithms where successfully implemented and they are tree to ten times faster than correspondning optimized CPU implementation..
