Mean value modelling of a poppet valve EGR-system

Because of new emission and on board diagnostics legislations, heavy truck manufacturers are facing new challenges when it comes to improving the engines and the control software. Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of this thesis is to create a mean value model for Scania's next generation EGR system consisting of a poppet valve and a two stage cooler. The model will be used to extend an existing mean value engine model.

We made an empirical study based on a questionnaire. Twenty-one registered nurses answered the questionnaire that consisted of mostly open questions. The result showed that almost everyone experienced that they gave dietcounselling and many nurses mentioned that dietcounselling was important. The majority of the nurses thought that they had enough knowledge to be able in order to deliver a fundamental dietcounselling but nobody considered that they knew much about vegetarian diet..

Utvärdering av Vissberga lakvattenbehandling

In connection with the admittance of the EC-directive (99/31/EC) in Swedish politic, through the constitution of waste depositing (2001:512) at year 2001, the rules about management the landfills and leachates tightened. At the landfill Vissberga in the municipality of Hallsberg, a leachate treatment plant was constructed just a year thereafter. This treatment plant consisted of an aerated pond with a following land treatment and a willow cultivation to replace the land treatment during the summer. In this case the parameters, which were estimated as the most important to reduce, were iron and nitrogen. The iron would react with the oxygen-rich water in the aerated pond and precipitate to ferric-hydroxide and than settle in a calm zone of the pond.

Betydelsen av skogens ålder och förekomst av lavar för renars val av vinterbetesområde :

This is a study on winter groups, ?siida?, of semi-domesticated mountain-migrating reindeers that move to lichen pastures in the lowland boreal forests during winter. The aim of the study was to determine reindeer habitat use in their winter ranges in a managed forest landscape. The reindeers use of three different types of forests was determined, 1) 100-130 year old, 2) 20-40 year old forest and 3) clear-cut areas. All sites were dominated by Scots pine, Pinus sylvestris, and had the same types of ground vegetation.

"Kränkningar går som i en cirkel hela tiden!" : Elever undersöker begreppet kränkningar i en fokusgrupp genom drama.

I mitt examensarbete har jag valt att försöka undersöka i vilken utsträckning det i en hemmastudio är möjligt att återskapa ett sound från en professionell inspelningsstudio. Denna fråga är intressant för mig då jag fastnade för hur en produktion lät i ljudbilden. Dels instrumentuppsättningen och deras rytmisering men främst soundet på helheten i mixen. Det kändes luftigt, stort och brett i lyssningsspektrat trots att det inte var så mycket instrument. Jag har alltid velat utveckla min förmåga att skapa och producera musik men har inte tillgång till så mycket kvalitativ utrustning.

Dialektanvändning hos barn med typisk utveckling : En jämförande studie mellan östgötska barn i olika åldergsgrupper

To explore how children use dialect, and whether the dialectal language develops during growth might be of interest from a speech language pathologist?s point of view as the dialect could influence the child?s speech. Previous research is often based on older material and/or examines the speech of adults.  In the present study, everyday language in groups of south- eastern Swedish speaking children was investigated. The aim of the present study was to examine to what extent typically developed children of the ages of  5, 8 and 11 years use dialectal language. A further purpose was to discover which dialectal characteristics that were present in the different age groups, and how they differed.

Torsby kommun kommunicerar för en yngre befolkning : En kvalitativ undersökning av en av kommunens målgrupper

AbstractThe purpose and vision for the municipality of Torsby are to connect with a younger population in the municipality by the year of 2012.This study is a qualitative survey of the target group ?the young ones? within the municipality of Torsby, which is the population between 17?35 years old.Because of the size and the different intrests between the individuals in this group it has been divided into three smaller groups.? High school students, 17-19 years old.? Returning seasonal workers, 20-26 years old.? People who has moved to Torsby and are now living in the municipality, 27-35 years old.The results of the study show that all the respondents believes that with the right communication channels a positive and strong communication between the municipality and the target groups can be reached. The message and the significance of the message are as important as the communication channels and all the target groups together would like to see a wider range of leisure pursuits that will suit the respective target group.The analysis and the results also show that the communication with the target groups should come about in different ways to be successful, both when it comes to fundemental reasons and choices of communication channels.The two youngest target groups has an adjacent and a similar need of well-founded and entertaining communication and information to rach a long-term result.The older group needs communication that will give them opportunity to reflect and concider the message, which means that the municipality of Torsby needs to adjust both the message and the communication channel for a quicker respons. This target group is also in need of further studies so the municipality of Torsby succesfully can plan a more detailed communication, this because the target group is a less homogeneous group than the two other target groups..

Topografins inverkan på markvattenhalten i ett jordbruksdominerat avrinningsområde

Topography is an important parameter for catchment hydrology, since it is a driver for water flow. Moreover, topography serves as a basis for hydrological models, e.g. ?Top-model?, which is based on a topographical wetness index (TWI). Few studies of TWI have been conducted on agricultural catchment scale. Four fields were studied in a Swedish drained agricultural catchment in order to evaluate the influence of topography on soil wetness.

Nollföljdsmodellering av transformator-Beräkningar av följdproblem vid ökad kablifiering på mellanspänningsnivå

Historically transformers with system earth equipment have been modeled as open circuits in zero sequence. This approximation has been satisfying, but lately it has been discovered that equipment on one side of the transformer have responded to faults that occurred at the other side. Most of these problems took place when the majority of the system on the secondary side of the transformer contained cables. These findings have led to questioning whether or not the former model of the transformer in zero sequence is correct. This report investigates if it is necessary to represent the transformer in zero sequence in another way than it is usually done today.

The value of an organization?s availability and transparency towards the public whenever and wherever it is necessary has increased.
