VVA-strategier för avgastemperaturhöjning på en HD-Dieselmotor
Regulations on the exhaust emissions of HD-diesel engines are becoming more and more stringent, and therefore, emission after-treatment systems are commonly used. These systems rely on catalytic conversion of NOx,CO , and HC emissions, and are thus dependant on temperature. At low load of the engine, exhaust temperatures are not sufficient for the after-treatment components. Therefore, means to increase the exhaust temperature while maintaining low emissions and fuel consumption are needed.The focus of this project has been to develop strategies for the lift profiles of exhaust and intake valves in the engine, with the goal to raise exhaust temperature in combination with low emissions and fuel consumption. The strategies have been tested in a single-cylinder research engine equipped with a hydraulic variable valve actuation system.
Testmetodik för vintertestning av el- och hybridfordon
With gas prices persistently rising, electric and hybrid vehicles are getting more and more common and in recent years several new electric cars have evolved on the market. Although the energy consumption and low emissions are a huge benefit of the electric cars, they inevitably suffer from high prices, short range and time consuming recharging periods. To be able to withstand the competition it is important that electric vehicles not only can withstand general were and tare, but also the harsh conditions that ordinary cars is exposed to in daily usage. The purpose of this project is to develop a test methodology which replicate situations that could appear in daily usage of electric or hybrid cars and to understand the problems related to usage of electric cars in winter conditions. This paper also discusses the major differences between hybrid cars and electric cars.
NATO:s luftkrig i Kosovo utifrån Wardens teorier
John A. Warden III is one the most mentioned air power theoretic of his time.He has written a number of theories concerning air power and the best way to use this to win wars.The author of this paper gives a short resume of what he consider are the central thoughts in John Warden´s theories. These thoughts result in four factors; Enemy as a system, centre of gravity, parallel attack/concentration and finally air superiority. These factors are then being used to inves-tigate if NATO used Wardens theories during the Kosovo war in 1999.The reason for the author to choose the Kosovo war specifically is due to the fact that NATO during the war only used air power as an instrument to get Serbia´s president Milosevic to the negotiation table but also the fact that this would turn out to be quite a challenge for NATO.The conclusion is that out of the four factors only one is traceable throughout the entire operation, and that is air superiority. Regarding the other three factors they can only be found in parts of the operation..

Vegetationsutveckling och mänsklig aktivitet under äldre Stenålder vid Döudden, Arjeplog kommun :
The landscape in the interior of Norrland has undergone dramatic changes since the deglaciation as a consequence of faultings, earthquakes and tilting of the landscape westwards. Archaeological investigations along former shorelines by the use of models of isostatic land uplift, have revealed many Mesolitic settlements in northern Sweden. Döudden, in the county of Arjeplog, has been investigated by archaeologists that identified settlements from 5200 BC. The objective of this study was to analyse the history of the vegetation and if the vegetation showed traces of human activity during early Holocene, by pollen analysis. The results indicate that the area had an established vegetation c.
Second screen - För Tv-serier
Today it is not unusual to use a secondary screen to accompany a primary screen. The possibility to integrate these two in the form of an application for the secondary screen have long been possible but have not been developed to full potential. This thesis aims to study the use of the extra information and functions this type of application would make possible and how this type of application could be used.For this study a prototype-application including a real time newsfeed and a static menu for a specific episode of a Tv-series was created based on the information collected in an online survey. The application was tested on a number of people who got to evaluate the experience in short interviews and were given the possibility to recommend changes in the application.The result after the study showed the people where torn about what kind of information would best fit the application but showed over all that a dynamic newsfeed with information continuously updated with the episode where most appreciated. The problem with the difference in interest around the categories would be solved first and foremost by the application being configurable so that every single user has the possibility to choose which kind of information to be updated in the newsfeed.
Design och tillverkning av en stereoanläggning med aktivt delningsfilter
This thesis is the result of the author?s interest in music and electronics, namely the design and manufacturing of a stereo sound system with an active crossover. In short it can be stated that an active crossover has many advantages over its traditional passive counterpart. The active design naturally results in a more complex system comprised of a multiple number of components. This report deals with the theoretical aspects of preamplifiers, crossovers and power amplifiers as well as power supply and control.

När bonderörelsen skapade partipolitik : Idéer och politik i Bondeförbundet under perioden 1910-1959
The aim of this bachelor´s thesis ist to analyze the idea progress in the party programs in the swedish Centre-party during the time 1910-1959. The progress in the party program is compared with the evolution of society during the same period.The bachelor´s aim is also to analyze how each new program is described in newspapers, two newspapers were chosen to make the comparison; Arbetet (a social-democratic newspaper), and Skånska Dagbladet (a centre-party newspaper). The result shows that the party in the beginning was conservative and against both capitalism and socialism. The start of the party was a reaction against the new electionsystem which was introduced in Sweden in 1909.The party took a clear standpoint for the Swedish farmers, but after 1933, they were standing for the whole countryside. In the 1940´s and the 1950´s the party became more like a social liberal party rather than an agrarian party only for the farmers.The party programs are not given much space in the two newspapers.
Anestesisjuksköterskors strategier för att förebygga postoperativ smärta
Sammanfattning Postoperativ smärtbehandling är otillräcklig trots ökad kunskap i smärtfysiologi och utvecklandet av nya farmakologiska riktlinjer. Obehandlad postoperativ smärta kan leda till komplikationer som fördröjd mobilisering, djup ventrombos, lungemboli, hjärtinfarkt, stroke och lunginflammation, vilka leder till ett ökat lidande för patienten både fysiskt och psykiskt samt ökade kostnader för samhället. Anestesisjuksköterskan lägger grunden för den postoperativa smärtbehandlingen före och under anestesin och ska arbeta preventivt för att patientens smärtbehandling ska vara tillräcklig. Syftet med studien var att belysa anestesisjuksköterskans strategier för att förebygga patientens postoperativa smärta efter generell anestesi. Semistrukturerade intervjuer genomfördes med fyra anestesisjuksköterskor på ett västsvenskt sjukhus och analyserades med kvalitativ innehållsanalys.
Följsamhet i läkemedelsordination vid hypertoni : med koppling till Orems egenvårdteori ? en deskriptiv litteraturstudie
Introduktion: Hypertoni är ett stort och utbrett hälsoproblem världen över. Det krävs följsamhet i läkemedelsbehandlingen för att minska risk för hjärt- och kärlsjukdomar, stroke samt renala sjukdomar. Omvårdnadsteoretikern Orem har sin teoretiska grund i egenvården. Enligt Orem är relationen mellan sjuksköterskan och patienten avgörande om sjuksköterskan skall kunna hjälpa patienten. Syfte: Syftet är att med utgångspunkt från Orems egenvårdsteori sammanställa aktuell forskning rörande faktorer som förbättrar följsamhet till läkemedelsbehandling hos patienter med hypertoni.
