After been told that an ordinary winter service for our combine should cost more than 20000 SEK, not included spare parts, I decided to write this paper about today?s requirement of the workshop on a farm. I think that the lack of proper premises is the reason way not more of the ordinary machinery maintenance or upkeep is performed on the farm. When I did my literature survey I found that the Swedish environmental code, set by the Swedish law regulate how drain or sewer should be built. The environmental code however leaves a lot for your own interpretation. It might not be so bad but it must be very hard for the local environmental office to interpretation the regulations, since they are the ones that gives permission for the sewer in your workshop.

Examensarbetet visar en selektivbedömning för lågspänningställverk T15 på SCA Edet bruk. Ställverket har ett 40 tal motordrifter och matas av en 690V transformator på 3,5MVA. Grundprinciper för de vanligaste lågspänningsskydden presenteras samt mer specifika detaljer om installerade skydd i aktuellt ställverk. Olika typer av selektivitet är kortfattat presenterat i rapporten. Vid beräkning och dokumentering med hjälp av datorprogrammet Febdok visade det sig att installerade skydd inte fanns med i programmets skyddsregister.

Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

IT (Informationsteknologi) används i dag mycket för att distribuera och förmedla information internt och externt. Ett bra verktyg för informationshantering är verksamhetens intranät. Arbetet handlar om användbarhet i små SharePoint-projekt. Med användbarhet omfattas faktorerna användarvänlighet, anpassning och användaracceptans. Små SharePoint-projekt (på under 300 timmar) innebär att det finns mindre resurser för att tillämpa användbarhet.Syftet med detta arbete är att undersöka utvecklare inom SharePoint sina åsikter och förhållningssätt kring användbarhet, samt hur användbarhet bäst kan uppnås i små projekt med begränsade resurser.

A Swedish company, company F, will establish a new factory in China. Company F is adivision within Company F. The factory in China will manufacture wire products. Thepurpose of this final thesis is to analyse which legal and practical measures the company hasto undertake during the process of localization to get approval from the Chineseenvironmental legislation.An analysis of the influencing factors on the environment from the production in theconstruction in Sweden was carried through. A material-balance was analysed according tothe flowchart of the production.

Den mekaniserade bataljonens främsta sensor att samla in underlag till underrättelsesektionen är spaningsplutonen. Spaningsplutonen på mekbataljon har bytt organisation över åren och gått från att vara ett terrängbils eller bandvagnsburet förband till sin nuvarande form med stridsfordon 90. Men har förbandet använts på rätt sätt sedan det tillfördes stridsfordon? Hur bör framtidens chefer nyttja plutonen för att maximera effekten?Arbetet baseras på de reglementen som finns idag samt intervjuer med personal tillhörande spaningsplutonerna och bataljonsstaber. Utöver det kommer en jämförelse med US Army Armored Cavalry göras..

Atlas Copco Tools develops and manufactures handheld industrial tools. Heat and surface treatments are used to provide the tools with certain properties. There are no routines for the choice of treatment or for how to specify treatment on drawings. Production documents that are sent for production abroad may not be clear enough. Some treatments are known as trademarks and there are no instructions for how to specify these on drawings and in CAD-models.The purpose of this master thesis work is to create recommendations for the procedure of choosing heat and surface treatment.

The project focus on combustion of softwood pellets and pellets in a 40 kW grate fire reactor at TEC-Lab. Dept Applied Physics and Electronics at Umeå University. Experiments were performed at four primary airs to fuel ratios (0.7 to 1.3), where aspects such as temperature profile, levels of gases (CO and NO), sintering-/-slagging and unburned fraction of the ashes were studied. Four different fuel loads were used for wood pellets (10, 20 and 30 kW) and one fuel load for straw (10 kW). Combustion of straw proved very difficult to ignite, and also led to other combustion-related technical problem such as slag formation due to the relatively low melting temperature-/-slag temperature of the straw.

Large areas of forests in the tropical region have during the last decades been lost and converted to new land uses while other areas have been degraded into secondary forests. These secondary forests need to be restored and rehabilitation through enrichment planting and liberation may help to speed up the recovery process. The objective of this thesis was to evaluate a rehabilitation method that includes enrichment planting, slashing of weeds and girdling of unwanted trees. The site for the project is situated in Sabah, Borneo in a secondary forest which had been logged and burnt by a wildfire. The project?s goal is to rehabilitate and increase biodiversity through enrichment planting of seedlings mainly belonging to the family Dipterocarpeaceae (dipterocarps).

A new type of device for measuring thev m& ?rate of fuel sprays from a diesel fuel injector has been developed and the various steps in the development are described. The device works by deflecting all of the sprays from the injector at the same time by using a bell shaped deflector. A load cell consisting of a machined steel part with strain gauges mounted on it measures the resulting force. The shape of the curvature in the deflector bell shape has been evaluated by photographing the flow in a 2D?version of the curve shape.
