Validering av glidande statorfötter på Hissmofors G6 och G7

Jämtkraft AB has recently modernized its hydropower station at Hissmofors by replacing four older worn out units with two new units. The generators uses a concept with sliding stator feet to deal with the thermal movements that occur in the stator during operation when the unit is operating intermittently. At other sites, this method revealed shortcomings in the reliability. This has made Jämtkraft AB feel uncertainty about its function and therefore want to investigate it during an early stage. The generators have a built-in monitoring system for the sliding stator feet and by using data from there the function of the sliding stator feet has been investigated. The study focused on how the different stator feet move relative to each other and how the eccentricity and deviation from roundness changed during operation. The results show that there are several indications that the function of the sliding stator feet is not satisfactory.

Hållfasthetsberäkning av handikapanpassad lyftanordning

Most major companies today have a visual identity. It answers questions like: which font do I use? and when can I use the logo or not? Westinghouse Nuclear Fuel in Västerås have a visual identity but no guidelines for the employees to follow. Further-more, rollups and rollup handouts produced by Westinghouse are not mentioned in the visual identity. ?erefore the external information from Westinghouse is someti-mes, both by employees and customers, perceived as not uniform.

Analys av designalternativ för snabbare dynamik i kolkraftverk med koldioxidavskiljning

Combustion of fossil fuels is today the dominating source of energy. During combustion,carbon dioxide is formed. The carbon dioxide accumulates in the atmosphere,which raises the global average temperature on earth through the so called greenhouseeffect. The only way to reduce the emissions of carbon dioxide from combustionin a coal fired power plant is through carbon capture and storage (CCS).Post-combustion capture is a technology to separate carbon dioxide from the uegas after the combustion for efficient transport and storage. The steady state operationof coal fired power plants with post combustion capture has already beenthoroughly investigated on a pilot scale, however much work remains to investigatethe plants dynamic operation.

Akuta effekter av assisterade hopp på kvinnliga idrottares hoppförmåga

Vertical jumping ability is an essential skill in many sports. The aim of this study wasto investigate the acute effects of assisted jumps on subsequent countermovementjump (CMJ) performance by female athletes. Nine healthy, trained female subjectsvolunteered to participate in the study. In a randomized order, they performed oneregular warm up protocol before testing their CMJ baseline value, and one warm upprotocol with an addition of five assisted jumps at 30% body weight reduction beforeanother CMJ test. Elastic cords attached to an overhead pulley system and to aharness around the subjects' upper body were used to reduce the body weight.Significant improvements were noted in jump height, 2.3 cm (7%), positive forceimpulse, 4.7 Ns (2%), vertical take off velocity, 0.1 m/s (3%), countermovement time,0.1 s (12%) and breaking time, 0.1 s (14%), p.

Sverigedemokraterna i Ronneby : Teorikonsumerande studie med fallet i centrum

With varied electoral success for anti-immigration parties across Western Europe, Sweden is often held as an example where anti-immigration parties have been less successful. This have caught the interest of many scientists around the world and have recently developed theories on a subnational level when testing Sweden?s municipalities, on why they have failed here but not in other countries. But in the election to 2010, Sweden now joins the rest of the Western-European countries in having an anti-immigrations party in the parliament.This paper has tested three theories on a Municipality that has shown evident support for the Sweden democrats, both in the local and the national election. This is done with a qualitative approach, made up from interviews with the local established parties.

By literature, pedagogue interviews, and interviews with pupils at the age of ten years old and by action research is the way that I have searched for an answer for my question. The main result is that fantasy, creativity, courage and lust are important parts to develop in the job of raising the self-image.

Avståndsvarnare till Mobiltelefon

This report describes a study, description and testing of parts to an application adapted to the operating system Android. The application is supposed to measure the distance to a car ahead. Apart from distance measurements the ability of the application to calculate its own speed with the help of GPS is tested. From these two parameters, speed, distance and some constants the theoretical stopping distance of the car will be calculated in order to warn the driver if the car is too close to the car ahead in relation to its own speed and stopping distance.Tests were conducted on the different applications that were programmed and the result showed that the camera technique in the mobile phone itself limits the maximum distance of the distance measurement application. The max distance the tests in this thesis revealed was approximately 5 meters.

Det avbrutna samtalet - reklamformatets betydelse i podcastmediet

Marketers are today confronted with new forms of media and tend to use different strategies to exploit these media. The podcast medium has emerged in a time of changes in terms of media planning.

Ett objekt : om arkitekturen i ett föremål för handling

This thesis is covering my design of an architectural object for the use in a pedagogical setting. The purpose is to create contextual premises for students, making possible the testing of designs, involving plants suitable for the urban environment. Hence, the main features in the object design is suggestive to the urban outdoor rooms - rooms that are formed amongst the city facades. The thesis is also about the design process set out from a technical reality, based on camera imagery. To a large extent, the thesis consists of reflections concerning the object's function towards pedagogy, perception and materials. Furthermore, the object claims to be a hybrid between architecture and landscape architecture.

Cementstabilisering av Biltemas andra lagerbyggnad i Halmstad

This is a technical report about cement stabilization in general and the stabilizationprocess during the construction of a warehouse in Halmstad, Sweden in particular and iswritten at the section for economy and technology at Halmstad University incollaboration with NCC Anläggning.NCC encountered variations in compression strength in the stabilized material on the firstwarehouse that they constructed for the company Biltema. In our report we used thestabilization process of the second warehouse for the same company as a reference todetermine what could be done to get a more homogeneous result for future projects.We also looked in to what testing method is the most suitable to determine the result ofthe stabilization.After interviews with people involved in the process and visits on the work site we havecome to the conclusion that the most probable cause to the variations in compressionstrength is segregation in the ballast material. This segregation can occur in severaldifferent occasions in the process such as during the production, transportation andhandling on the work site.Other causes for the variation can be improper compaction, overlapping stabilization insome places and different duration of hardening of the samples that are tested.The best way to do in situ test of the stabilized material is to do seismic investigations asthose are non-destructive tests in comparison to taking core samples and you can discoverany cracks or air bubbles in the material..
