To design new and high tech products the engineers rely more and more on computer based simulations to investigate the properties and behavior for a component or system.To verify these computer based simulations the dynamic properties for the components of the drivetrain needs to be verified. Therefore measurements of the stiffness and vibrations for the rear axle has been performed. This report show how the measurements has been implemented and evaluated, along with some interesting results for the rear axles properties.The static stiffness for the drive shaft along with the axle-gear has been determined. It is found that the stiffness for the whole rear axle is near the stiffness for the drive shaft, which means that the drive shaft becomes the dominant component of the system and affects the rear axle stiffness the most. The measured stiffness of the driveshaft is close to its theoretical stiffness.The stiffness for solely the hypoid-gear have been calculated using the stiffness for the rear axle and driveshaft, and thus has a range for the stiffness of the hypoid gear been determined.The backlash for the whole rear axle and for some individual components has been determined, where the backlash between pinion and crown-wheel has negligible impact on the total backlash.Measurements of the crown-wheel and pinion movements have been conducted, where the direction of movement is consistent with the theoretical direction of the forces.The vibration measurements show that the vibrations are more severe at certain rotational speeds.

This thesis has been performed at Scania CV AB Technical Centre in Södertälje and its aim hasbeen to study the causes and effects of deformations in the interface between the rear axlehousing ADA1100 and the central gear house R780 during operation. Design changes that wouldincrease the sealing capability of the studied interface are also suggested. Finite element (FE)and CAD software have been the primary tools in this study.Finite element (FE) simulations are used in the industry to predict and develop engineeringdesigns. The main motive for FE simulations has traditionally been to identify weak spots in thedesign, regarding high tensions and large deformations.The FE model is an aggregation of submodels and interface models that represents the rear axlehousing, suspension, central gear, central gear housing, wheels, bolts and weldings, and theirinteractions. The submodels have different material properties and they are connected withcontact interface models.Boundary conditions are defined on the bushings in front of the rear axle and on the air bellowsbehind the rear axle.

Genom våra två fallstudier har vi undersökt formuleringsarenans intentioner vad gäller elevinflytande i förhållande till hur dessa tar sig uttryck i praktiken. För att finna formuleringsarenans intentioner har vi använt oss av Skolkommitténs tre utgångspunkter om varför elever skall ges inflytande i skolan. Skolkommittén har på ett konkret och förståeligt sätt redogjort för tre motiveringar till elevinflytande vilka benämns som: ?Mänsklig rättighet?, ?Demokratifostran? och ?Elevers inflytande över sitt lärande?.  I vår text har vi eftersträvat att ringa in ämnesområdet och ge läsaren en tillräcklig bakgrund för vidare läsning. För att vidga vår förståelse för elevdemokrati idag ser vi det med andra ord som angeläget att mer översiktligt och kort redogöra för en historisk tillbakablick.

Driving simulators are a very important part of the research that is done at VTI. Enhancing the realism and creating a better driving experience in the simulators are very important and an ongoing work process for the engineers and researchers who work with the simulators. This project has been done as a part of this developing process and the purpose is to enhance the realism of the rear-view mirrors.Simulating realistic rear-view mirrors has been demanded, not only from the researchers at VTI, but also from car and truck manufacturers. To achieve a realistic mirror view a method to measure and parameterize real mirrors has been developed. The code for the existing graphics system has also been redone to be able to handle the new types of mirrors introduced..

The purpose of the present study was to examine effects of driver, vehicle, and environment characteristics on Collision Warning System (CWS) design. One hypothesis was made that the capability of collision avoidance would not be same among a driver, vehicle, and environment group with different characteristics. Accident analysis and quantitative analysis was used to examine this hypothesis in terms of ?risk? and ?safety margin? respectively. Rear-end collision had a stronger focus in the present study.

Jönköping's municipality requested a diploma work witch would present the experiences, as arisen during the existence of the echo village Smeden.To recive information for the background, literature at the university library were searched at the database "Libris" with words like "echo village" and "ecological living".Data was retrieved from 28 questionnaires that were sent out to the inhabitants of the echo village Smeden. The questionnaires contained questions about experiences, opinions, ideas and thoughts about living in this echo village. The results were analyzed and presented by diagrams and tables and showed that the inhabitants where most unsatisfied with the sewer and the system of the toilet. In the opposite the inhabitants experienced that the remaining systems were in satisfactory and the majority of the inhabitants were very pleased with their living conditions.Conclusions of this study are that an echo village would be a suitable alternative to an ordinary living and that ecological living would be something that would work well even in the future. An important thing to remember is that the systems of the households must be easy for the inhabitants to maintain otherwise the environmental thinking would be in risk of failure if some don?t have the energy to manage this properly..

The purpose of this study is to explain if the existence of ethnic groups in Rwanda has complicated its democratization and explain what opportunities Rwanda has to be democratized. To fulfill the purpose of the study, I intend to answer two questions: 1) Does the existence of ethnic groups obstructed democratization in Rwanda? and 2) What opportunities has Rwanda to be democratized? To answer the first research question Dahl's theory of subcultures and democratization is used and to answer the second research question van de Walle's theory of democratization is used in the region of sub-Saharan Africa. Literature used in the study are Dahl's Polyarchy and van de Walle Africa?s range of regimes and Freedom House annual reports.

In this thesis, a transparent model of the human head has been constructed which was filled with a substance that represented the brain. This model was later crash tested. This was done in order to examine how a transparent model of the human head can be constructed to generate accurate data from crash tests. It was also done in order to examine how impacts on the front of the head can deform the rear of the brain. When a head is decelerating, the brain moves forward inside the skull and may hit the front of the skull.

When the producers? responsibility for packaging was introduced in Sweden in 1994 the industry set up public recycling stations to facilitate the collection of the waste material. In order to establish recycling stations at suitable locations the municipalities assist the industry?s service organization for operation of the recycling stations, the Package and Newspaper Collection Service (Förpacknings- och tidningsinsamlingen, FTI). The objectives of this thesis are to improve the service of the public recycling stations within Lidingö town and to increase the accessibility to these stations for the inhabitants of Lidingö.

Rapporten beskriver förslag på framtidens ?Rear Seat Entertainment? som baseras på användning av pekskärm, istället för de DVD-baserade TV-skärmar som finns i t ex Volvo S80 i dagsläget. Projektet utfördes som ett examensarbete inom integrerad produktutveckling vid Högskolan i Skövde. Syftet med arbetet var att hitta lösningar som möjliggör användning av ?touchteknik? som kräver armavstånd till displayen.

The purpose of this study is to illustrate if structural factors to welfare indicators and the internal organisation of handle social assistance in combination with dominating ways of living with their values and norms can be used to explain why the costs of social assistance are low in Säffle township. The character of this study is exploratory, though important aspects in this case was unknown. The empiricism come from descriptive secondary statistics and from qualitative interwievs with three inhabitants in Säffle, whom are experts which means they know the township of Säffle and it´s inhabitants well. Säffle has been studied from four perspectives, of which the first two have a top- or macroperspective. In the study appears two divergent pictures.

In recent years, the characterization of the Third World and its inhabitants in West-originated children?s books has been subject to debate. Media attention around a selection of books has generated discussions on how this relates and aligns with Sweden?s national teaching curriculum. The objective of this study is to explore how a selection of authors, born in Western countries, have characterized and presented the Third World and its inhabitants in its literature.
