Utredning av frekvensregleringens påverkan på mekanisk utrustning i en kaplanturbin

As a consequence of increasing wind power installations in the Nordic grid the last years, the need for regulating power has become larger. In the Nordic grid, regulating power is mainly provided by hydro power. One part of the regulating power is called frequency control, which ensures that the grid frequency is stable and close to 50 Hz.However, setting the turbine into frequency controlled operation may cause stress and wear of the components in the mechanical control system. Frequency controlling implies large and frequent servo forces and longer travelling distance of the sliding bearings in the Kaplan turbine.Based on one selected Kaplan turbine, Selsfors G1, measurements and MATLAB calculations have been performed in order to determine forces and movements of the linkage system. With these forces and movements as input, stresses and fatigue have been determined as well as sliding distances, bearing pressures and wear of bearings during a typical lifetime of 40 years.The results indicate that no severe wear exists on the bearings during 40 years of service.

A further aim was to investigate whether the intervention influenced health professionals' attitudes to breastfeeding.Method/Design: An experimental study with quantitative approach in the form of questionnaire survey was conducted.

Biological control of Fusarium wilt on tomatoes : use of Bacillus subtilis and interactions with the earthworm Pontoscolex corethrurus in a Kenyan highland soil

It is important to investigate the potential of biological control measures in agricul-ture, especially where economic issues restrict the use of expensive inputs or when there are environmental concerns about toxicity of agrochemicals. The bacterium Bacillus subtilis has proved promising as a biocontrol agent (BCA) in suppressing various plant diseases and it has also been shown to promote plant growth in certain cases. During this study, the effect of B. subtilis on Fusarium wilt (caused by the fungus Fusarium oxysporum) on tomatoes, as well as its effect on the earthworm species Pontoscolex corethrurus was investigated. Furthermore, the combined ef-fect of the BCA with P.

Ett kompatibelt control package? - en fallstudie av Metso Power AB

Bakgrund: Under senare år har många företag valt mer processorienterad inriktning påverksamheten, framförallt i syfte för att förbättra kundvärdet. Många företag har enmer hierarkisk struktur i utgångsläget, vilket innebär att vertikal och horisontellstruktur kombineras. Ett vanligt misstag är då att nya processorienterade styrmedelinförs, utan att existerande vertikalt orienterade styrmedel tas bort. Detta leder tillatt företagets styrmedel sänder ut motstridiga styrsignaler. För att öka företagetsmöjlighet att uppnå uppsatta mål, så krävs det att dess styrmedel är kompatibla.I sämre tider är det vanligt att företag formulerar mål med Net Working Capital somgrund.

Prestanda och precision pa? en enkortsdator i ett system med realtidskrav

The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.

Det kaotiska laboratoriet - En kvalitativ studie om organisationen i IT-startups under olika perioder

The great economic impact of startups on society has made these types of companies an increasingly popular subject for research. Though no single definition of the word startup currently exists, one could define it as a temporary organization in search of a scalable, repeatable, and profitable business model. Seen from a historic perspective, tech-startups in particular should be considered a new phenomenon and the topic is still relatively unexplored. This study investigates the structure in tech-startups during their first months of existence and compares it to the structure that prevails when the companies have recruited at least five additional employees. In addition, the study explains why these changes occur.

Livskvalitet och social livssituation hos patienter som genomgått Ö-cellstransplantation

Aim: To investigate the quality of life and the social life situation, with special focus on the consequenses of fear of hypoglycemia (FoH), in Islet transplanted patients.Method: 11 patients were included, four women and seven men, who have been Islet tranplanted at Uppsala University Hospital during the years 2001-2009. Two questionaires, Short Form 36 (SF-36) and the Swedish version Hypoglycemia Fear Survey (Swe-HFS) were used to investigate the quality of life, in relation to fear of hypoglycemia. Also, telephone interviews were conducted to investigate the patients social life situation in relation to FoH, after Islet transplantation and were analysed using content analysis method.Results: The mean value for quality of life was lower than that in the normal population. Three out of ten patients experienced FoH. Three predominant themes were revealed, one theme associated with pre- transplant, was ?Struggle for control of Social Life Situation? and two themes associated with post-transplant, were ?Regain power and controll of  Social Life Situation? and ?At Peace with the balance between the Present and the Future?.Conclusion: The patients experienced improved control over social life situation and quality of life in relation to FoH may been improved following islet tranplantation..
