Detta examensarbete har utförts vid Linköpings universitet i samarbete med Scania Transmission i Södertälje och behandlar kravsättning av ytstrukturer samt processer för hårdbearbetning av kugghjul och axlar. Aktuella artikelritningar innefattar endast krav för Ra-värde, den aritmetiska medelavvikelsen för ytjämnhetsprofilen (R-profilen). Förslag på nya parametrar enligt av Scania tillämpade SS-EN ISO standards har tagits fram, detta för att ge en noggrannare beskrivning av vilken ytstruktur som skall uppnås. Resultatet är generellt tillämpningsbart men fokuseras mot kugghjulens hål, plan och diametrar. Vidare presenteras en jämförelse mellan metoder så att transmissionsverkstäderna kan tillverka kugghjul/axlar på ett kostnadseffektivare sätt.

Land systems Hägglunds manufactures and sells different kinds of combat vehicles and terrain vehicles. Since the demands for bigger and stronger vehicles increases all the time, so are the demands on shafts, gears and other transmission details.

Japanese encephalitis virus (JEV) is one of the leading causes of acute encephalitis in humans. The virus is spread by mosquitoes, mainly belonging to the Culex species. The main reservoirs are considered to be birds and pigs, with pigs constituting the most important reservoir in regard to human infection. During the last few decades the production of pork has increased significantly in Vietnam. With 90% of pigs being kept in households owning 10 pigs or less, pigs are widely spread across most parts of the country.

The study aims to reduce energy consumption in apartment buildings where individual metering and charging of heat is applied. The aim is to develop planning and design for individual metering and charging in apartment buildings.The study is based on literature review, interviews and case study that include analysis of existing documents. Interviews were carried out with the property developer and the involved consultants who planned the apartment building Yasuragi. To investigate the differences the condominium association has noted in heat consumption between flats, the debit values of the heat were used to discern which houses that were furthest from the average consumption. On these flats there were temperature measurements and thermal photo shoots made for discriminating behavior and possible construction techniques which could be the explanation for the heat spread.Boverket shows that the consumption of heat can be reduced by 10-20% after insertion of individual metering and charging in an apartment block.

Sweden has long had access to low electricity prices due to the wide availability of hydro and nuclear power. This has now changed because of today's rising electricity rates resulting in increasing heating costs for properties, especially in the properties with electric heating systems."Ankaret" is a parish for "Svenska Alliansmissionen", which is located at "Gullbrannagården".The parish has installed electrical radiators and an exhaust ventilation system that makes the energy demand high due to the large ventilation flows. The building was built as the price of electricity was still low and would reduce energy use today by combining its heating system with an air/air heat pump. The heat pump delivers more heat into the room than the electrical energy that it uses. This lowers the electricity needs.

This diploma work project is a product development project which purpose is to redesign a braking system for a walking frame. The system that was developed diverges the force from the user to braking power, and includes a service brake as well as a parking brake. The most important components of the system are a grip handle on where the user holds on to and a braking handle on which the user operates the brake from. The system also includes a power transmission component, braking package and other mechanical components. All of the components wasn?t developed in this project, several off them has been reused from the existing system.This product has been developed to meet the requirements and standards presented from the principal, Ahlberg Leber.

SammandragProblematisering: Tilla?ter kvinnliga revisorer en la?gre ma?ngd av earnings management a?n sina manliga kollegor? En va?ldigt liten del av den befintliga kvantitativa forskningen inom earnings management har fokuserat pa? om det finns skillnader i hur kvinnliga respektive manliga revisorer va?ljer att begra?nsa earnings management i ett fo?retag. Dessa underso?kningar har gjorts i la?nder som enligt World Economic Forum (WEF, 2013) rankas bland de ho?gsta i va?rlden na?r det kom- mer till ja?msta?lldhet, och det finns da?rfo?r en osa?kerhet ifall deras empiriska resultat kan appliceras i andra la?nder. A? andra sidan finns det forskning som tyder pa? att sociala strukturer sa?som ja?m- sta?lldhet pa?verkar inte bara skillnaderna mellan kvinnor och ma?n utan ocksa? synen pa? resultat manipulering.

Vaccination of fish can be assumed to cause pain. This study was designed to see if we can minimize the suffering of fish following vaccination. Fishes are cold-blooded animals and thus more primitive than warm-blooded animals. Despite this, many organs, e.g. the nervous system, have the same basic structure as that of other vertebrates. The fibre system for conducting pain is more diffuse than in humans.

Företag och organisationer arbetar i dag i projekt. Att arbeta i projektform kan medföra både för- och nackdelar när det gäller kunskapsöverföring. Kunskapsöverföring är viktig eftersom den möjliggör för medarbetare att använda sig av gamla lösningar på nya problem. Syftet med uppsatsen är att titta på vilken kunskap som sprids och på vilket sätt det görs mellan ett mellankommunalt projekt Kompetensare 2.0 och dess föregångare Kompetensare. Kompetensare 2.0 är ett mellankommunalt projekt mellan 10 olika kommuner som ska implementera arbetssättet och arbetsmodellen från Kompetensare.

Syftet med detta examensarbete är att analysera och utvärdera olika material styrningsmetoder inom tillverkningsindustrin för att få konkurrensfördelar. Scania som var uppdragsgivare ville att vi konkret skulle titta på vad som kan främja deras produktion. Scanias motorproduktion står inför en stor omläggning av materialstyrningsmetoder i och med att man ska bygga om och förbereder en ny produktionsanläggning i befintliga lokaler. Denna undersökning görs innan omställning av verkstaden, delvis för att kunna vara en jämförelsestudie efter att förändringen är slutfördArbetet har fortskridit i följande steg; först har vi sökt finna en problemformulering och en vetenskaplig grund att arbeta utifrån. Därefter har vi gjort en omfattande litteraturstudie som följts av en noggrann kartläggning av nuläget på Scania motorverkstad.

The reason for performing an Environmental Impact Assessment (EIA) is to incorporate environmental concern in different kinds of plans and projects. The purpose of such an assessment is to identify and describe direct, indirect and cumulative environmental impacts.Geographical Information System (GIS) is a tool that can be used to combine spatial extension of both sensitive areas and different environmental impacts in a quick and easy way. Because of that, descriptions of environmental impacts and motivation of different standpoints on a specific issue can be more correct and easier to make if GIS is used as a tool.Hence, GIS can contribute to improve the quality of Environmental Impact Assessments. If the benefits of using GIS are to out weight the costs, geographical information of satisfactory detail, actuality and accuracy need to be available at reasonable prices.In this paper, case studies are carried out for three different geographical analyses to investigate the use of GIS as a tool in EIA. From these case studies, more general conclusions about the benefits and limitations of using GIS for Environmental Impact Assessments are also drawn.

Examensarbetet är utfört på Volvo Construction Equipment Components AB i Eskilstuna. Där tillverkas transmissioner och axlar till hjullastare och ramstyrda dumprar. Uppgiften har varit att ge förslag på en layout med bästa potentiella monteringsupplägg på transmissionsmonteringen, baserat på prognostiserad volym år 2006. Stationsmontering är det rådande produktionsupplägget. Det faktum att monteringstiden är lång och att det förekommer dolt montage gör det lätt att glömma detaljer.

Energy issues are constantly increasing attention in today's society. People's impact on Earth isentered in more contexts. Many discussions are about how the entire social structure needs to bestreamlined in order to achieve sustainability. The residential and service sector accounts for 39 % oftoday's total energy consumption in Sweden and the increasing electricity prices have made buyersmore interested in energy issues.There are many buildings in need of refurbishment today, including all the apartments that werebuilt in the 1970s to reduce the housing shortage at the time. 650 000 apartments of one millionapartments were built during the so-called the one million program and is currently in need ofrefurbishment.
