Konstruktionstudie av en ångexpander
This thesis applies to a novel steam expander, one part of a steam engine system, a wobble plateengine. The piston in the expander moves axially with the outgoing rotating shaft and is locatedon a plate, why the engine type is called axial engine. When steam is applied to the plungers theplate wobbles creating a rotation on the shaft going thru the wobble plate. The steam expander issupposed to be used in exhaust gas recovery (bottoming cycle) applications and small scaleenergy production. The commissioner is Ranotor Utveckling AB.

Vätedriven förbränningsmotor : Klarläggande av framtida hållbarhet
Today when new and harder demands on CO2 emissions are developed, vehicle manufacturers must work to develop new engine solutions to new kinds of fuels to replace fossil fuels. A fuel that could be applied is hydrogen. When hydrogen is combusted only water vapor occurs. Hydrogen is known to be explosive and flammable. These properties are both good and bad for combustion.
Zilent Ocean : EL-KONVERTERING AV INOMBORDSMOTORER TILL SEGELBÅTAR
Through extensive research it has shown that today?s sail boat owners are very frustrated concerning the limited choice of engine alternatives offered by today?s market. Besides rising fuel-costs, environmental awareness is very important in today?s society. Hence it is vital to find alternative environmental-friendly motors and replace combustion-engines. Zilent Ocean is an extensive project within Development engineering program at Halmstad University.
Sökmotoroptimering : Metoder för att förbättra sin placering i Googles sökresultat
This paper is a literature study on search engine optimization (SEO) considering the leader of the search engine market: Google. There´s an introductory background description of Google and its methods of crawling the Internet and indexing the web pages, along with a brief review of the famous PageRank algorithm. The purpose of this paper is to describe the major important methods for improved rankings on Google´s result lists. These methods could be categorized as on-page methods tied to the website to be optimized or off-page methods that are external to the website such as link development. Furthermore the most common unethical methods are described, known as ?black hat?, which is the secondary purpose of the text.
Regressionsmodellering av dynamiska råemissioner från statiska mätningar
By using steady-state measurements for predicting emissions under a dynamic drive cycle wouldsave a lot of time and money for the exhaust aftertreatment specialists at Volvo cars. The idea forthis thesis has been to investigate if statistical regression models can be used with good accuracy.Questions included are for example if common operating variables such as engine speed, air-fuelratio etc. is sufficient to predict engine-out emissions over the engine operating range with goodaccuracy. Focus was set on the modelling of warm engine, but also the more complex engineheat-up phase was investigated since it is a great contributor to total emissions. While NOxcouldnot be measured because of malfunctioning measurement equipment, only HC, CO andtemperature at inlet of first catalytic converter has been modelled.
Etik, moral och myndighetsutövande
Militär och polis har vid en hastig överblick en gemensam nämnare, nämligen legal våldsanvändning som en väg att lösa sina respektive uppgifter. Vad ställer detta för krav i fråga om etik och moral på respektive yrkesgrupp? Finns det fler likheter och vad finns det för skillnader, ur ett etiskt och moraliskt perspektiv? Syftet med denna uppsats är att identifiera vilka likheter och skillnader i krav på etik och moral det finns mellan officerare och poliser. Detta sker genom att beskriva vilka krav som ställs på en officer för att sedan beskriva vilka krav som ställs på en polis. Därefter sker en jämförelse och en analys i syfte att tydliggöra de likheter och skillnader som identifierats. Uppsatsen visar att likheter förekommer i fråga om krav på att behålla sin etik i perioder då den inte sätts på prov och efter långa tider av passivitet i verksamheten.
Alternativ motorinkapsling
The problems caused by the current engine casing in aluminum for Volvo Buses Corp. are the mainfoundation for this degree project. Lack of maintenance combined with a construction poorlyadjusted for assembly has resulted in the fact that the engine casings rarely get reassembled whenthe service is completed.The degree project has mainly been following ?Olssons.

Feldiagnos för RM12 baserad på identifierade modeller
The jetengines of today are growing in complexity. Reliability for aircraft engines are of extreme importance, mainly due to safety reasons but also economical ones. This master thesis deals with faultdiagnosis in the turbine section of RM12, the engine used in Saab/BAe's Gripen. Three different faults which can occur in the turbine section was studied. These faults are: clogged fuel nozzle, hole in outlet guide vane and sensor fault.
Konceptstudie av Waste Heat Recovery System på Tunga Fordon
In today?s fast growing and closely connected society, a reliable and energy efficient transportation system is more than ever desirable. Nowadays the significant part of the transportation sector?s energy demand is supplied by fossil fuels.Improving energy efficiency in combustion engines will result in reduction of fuel consumption and CO2 emissions. A modern internal combustion engine has an efficiency of 30-45 %, where the most energy loss occurs as result of heat losses in the exhaust and cooling systems.
Fysisk träning för ordningspoliser : Har fysisk träning någon betydelse för den stillasittande polisen?
Research shows that policing is mostly sedentary but physically and mentally demanding tasks occur and that policing includes factors like police inherent stress which may impair the health of police officers. Research has also found that physical exercise can play an important part for coping with these negative elements associated with policing. The overall purpose of this study is to contribute knowledge about the importance of physical exercise for policemen. The study is based on five semi-structured interviews with police officer?s working with emergency response.
Corporate Opportunity : Förbudet för styrelseledamot och verkställande direktör att utnyttja affärsmöjlighet som faller inom bolagets verksamhetsområde
The corporate opportunity doctrine constitutes a prohibition for the directors and officers of a company to pursue for themselves any opportunity which falls within the scope of the corporation?s business. In Swedish law the doctrine has not yet seemed to attract any greater attention. This doctrine has been the focus of a multitude of cases in a both American and English law, however mainly in the America law. Therefore, the American legal framework can serve as guidance in trying to define the doctrine as it has developed, or perhaps more correctly not developed, in national law.The perhaps most crucial question to be answered in the area of corporate opportunities is how the law indentify an opportunity as a ?corporate? one.
Områdets polis eller polisens område? En analys av hur områdespolisen i Bergsjön gör sig relevant för sitt område och sin organisation
The aim of the thesis is to illustrate how a group of community policing officers makes themselves relevant to their community, this in relation to wider organizational circumstances and exterior structures of society. Earlier research on the subject tells us that community policing can be proactive and crime preventing in such a way that the confidence and trust in the police is increased. Research is also making clear that proactive police work is hard to measure and evaluate, which is why my contribution to the field is to explore how this effects the way the police officers in Bergsjön, Gothenburg is making themselves relevant and the way that they see themselves as community policing officers. The relationship police ? community will be regarded as how someone treats their audience, attentive to its feedback, in order to get ones message out, in this case confidence and trust in the police, under influence of the audit society.To achieve the aim of the thesis, participating observation was chosen, to experience the police officers everyday work.
