During the migration season in 2013 a study on spawning migrating salmon and the effect of water flow on the behavior was conducted of the salmon at the Forshaga hydropower station in the River Klarälven. The River Klarälven with its nine hydropower plants on the Swedish side, constituting migration obstacles for the migrating salmon. Fortum Generation AB has together with the County Administrative Board restored a salmon trap at the lowermost hydropower station in Forshaga, aiming at making it possible for the salmon to swim into the trap, and thereafter be transported by truck past the power plants and then continue their journey to the spawning grounds on their own. Unfortunately, it is believed that the trap does not work as well as it should. In this study, I focused on salmon position in relation to water flow and if the number of salmon that swam into the fish trap differed between salmon with previous experience of the trap (experienced) and salmon without experience (unexperienced).

Northeast Stockholm is a region developing fast. There is already a great need for new transport solutions for the people commuting to the city, since long queues slow down car traffic and the local railway, Roslagsbanan, needs to be upgraded to attract more travelers. The competitive advantage of rail?traffic over the car when it comes to greenhouse gases and air pollutants is another reason to develop Roslagsbanan.This report investigates the differences between car and train to create a basis for a proposed expansion of Roslagsbanan. Once the proposal is presented, costs, emissions reductions and public benefits are analyzed.

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.

A computer model based on minimization of the free energy, capable to predict contact angles and spreading transitions between Wenzel and Cassie mode for drops placed on surfaces with different topography were implemented in matlab. Simulations were compared with experiments documented in the literature. These showed that reported transitions between Cassie and Wenzel mode can be explained by minimization of the free energy. In this report, a study on the possibility of constructing water repellent paper surfaces with a combination of treatment with octadecyltrichlorosilane and topography changes, is included..

Bath has been a part of human history for a long time. Today bathing/swimming inmunicipal pools is for people of all ages and it is possible to take swimming courses,exercise or enjoy recreation. The municipal indoor pool of Hogdalen in Sweden wasbuild in the sixties and has had problems with high levels of heterotrophic bacteria. Thefacility has two larger pools, one adventure park for young kids, two smaller bath tubsand a jacuzzi. To improve water quality UV light and coal filter were installed inOctober 2009 to the already existing purification system.

This thesis takes its starting point in the humanistic cultural-geographical concept of place, with the aim of achieving a greater understanding of what constitutes the place Mon today. Mon is located in the northwestern part of Dalsland. Until 1879, the area was described as outlying land, but with the extension of the railway between V?nern and the Norwegian border, Mon's station community emerged. In the mid-20th century, all activities in Mon were phased out, and since then, the place has been inhabited by only about 10 year-round residents.

Abstract: The purpose with this study is to analyse the political debate about freedom of speech in Sweden and Denmark, after the caricatures of the Islamic Prophet Mohammed that the Danish newspaper Jyllandsposten published in September 2005. For this debate four political parties have been chosen. These are: Socialdemokratiska Partiet and Moderata Samlingspartiet in Sweden and Socialdemokraterne and Venstre in Denmark.An idea analysis has been chosen as method, and dimensions as an analysing tool. The overall result of the analysis is that right- and left political parties in Sweden and Denmark are more alike, than different in their political debate about free speech. They all wish for total freedom of speech, and see that as the foundation of the democratic society.

?Statistical Process Control? har för syfte att genom av statistiska metoder, mäta och analysera variation för att upptäcka särskilda orsaker till variation i processen och sedan genom eliminering av de orsakerna, förbättra processens kapabilitet.Inom SPC finns några begrepp som kräver lite förståelse, till exempel olika typer av variation, skapandet av styrdiagram och tolkning av detsamma för att hitta särskilda variationer. Till författarens kännedom finns idag inget spel som på ett enkelt och konkret sätt underlättar förståelse av dessa teorier.Inom område ?Lean Produktion? finns ett spel (?Lean-spelet?) som har för syfte att förklara begreppet slöseri, olika typer av slöseri i produktionsprocessen och hur man kan förbättra produktionen genom eliminering av de olika slöserierna inom produktionsprocessen. Syftet med detta examensarbete är att se på möjligheterna till ett liknande spel för SPC.Utgångspunkten för skapande av sådant spel var design av en monteringsprocess som färdiggör en produkt (i detta fall en traktor).

The quantity of methane emissions from sheep depend on several factors, for example, the composition of the diet, feed quality, the age of the animals, time of the day and maybe also breed and sex. A comprising literature review was made about which factors that affect the size of emissions. In addition, a questionnaire was sent to two farms, one with a more intensive production system and another with a more extensive system. Inventories of the two farms were made; the rest of the data needed to conduct the study was taken from literature and other sources. Meat produced at the more intensive farm caused emissions of 0.4 kg of methane per kg of bone free meat and the more extensive farm caused emissions of 0.9 kg methane per kg of bone free meat.

The objective of this study was to assess validity and reliability for five different owner-completed instruments evaluated to assess chronic musculoskeletal pain in cats. All of the instruments were questionnaires, three asking about behavioral changes, one about the degree of pain and one about quality of life. One of the instruments was written originally in Swedish, the other four instruments were translated into Swedish before use. Data available were records from 57 cats with no signs of pain and 11 cats with different pain-related diagnoses. The diagnoses were ensured by clinical examination including palpation and manipulation of joints, gait testing on a force-plate and X-ray scans. Instrument 1 was completed by 57 pain-free and 11 pain-affected cats.

I animation för film kan regissören ändra kameravinkel för att en karaktärs känslor ska förmedlas på ett tydligt. i ett spel har ofta spelaren kontroll över kamerans position men kan i vissa fall inte ändra kameravinkeln. I det här arbetet undersöks om en spelkaraktärs rörelser måste överdrivas mer i ett spel som använder Free Roaming Camera än i ett spel som använder First Person Perspective. En karaktär i ett tänkt spel animerades med olika grad av överdrift för att förmedla ilska. Animationerna visades sedan för ett antal informanter som fick bedöma hur trovärdiga de upplevde animationerna samt ange vilket sinnestillstånd de upplevde att karaktären hade.

Hydropower is the largest renewable energy source available in today's society. Operation and production is handled by high-tech electronics. This thesis is done on behalf of Statkraft Sweden AB who wants to explore the possibility of replacing the hydraulic cylinder with an electric actuator, generally as well as a case of a small power station on the river Nissan. Whether it is the chaplain or francis turbine vanes are actuated by hydraulic cylinders. Because of Gustavsberg hydropower is inconstant operation, this report is based on power calculations, which are read and computed according to the available hydraulic diagram.

FOU-stationen är en anläggning där man bedriver forskning och utveckling av LKAB'sprodukter. När den byggdes installerades även en dammutsugningsanläggning för att ta hand om damm som bildas vid krossning, siktning etc. Efter ett antal ombyggnationer och utbyten av utrustning fungerar nu denna dammutsugningsanläggning väldigt dåligt. Jag har gjort en utredning för att ta reda på varför det inte fungerar och vad man kan göra åt problemen..

This paper goes through solar energy and what uses it has. It is also a guide in the choice of solar collectors forthe real estate that I have drawn for the thesis work.Solar energy is a renewable source of energy from the Sun's light. Energy can be used to produce both heat andelectricity through solar collectors and solar cells. Some of the benefits of solar energy is that it is completely freeto extract, environmentally friendly and virtually maintenance-free. Disadvantages are that the technology isexpensive, does not cover the entire energy needs and takes a long time until it pays.
