This Master Thesis is a product development project that has been carried out in cooperation with Scania CV AB. The purpose has been to find the relationship between geometric parameters and the swirl number for an XPI- cylinder head in order to improve the design specification.The increased focus on environmental issues from society leads to tighter emission legislations for the truck manufactures. In order to drive the development forward considerable resources are spent on research and development on diesel engines and its combustion process. The inlet air has a significant impact on the formation of emissions and the flow that is desired is called swirl. Swirl is achieved by making the air rotate around the vertical axis of the cylinder.Earlier cylinder heads that has been developed at Scania CV AB have shown clear relationships between geometric parameters of the cylinder head and the swirl number.

Denna rapport beskriver ett examensarbete för högskoleingenjörsexamen i elektroteknik vid Växjö Universitet. Syftet är att konstruera ett styrsystem till en robotbil, ett program som hindrar bilen från att krocka med omgivningen. Roboten ska även kunna styras från en dator via ett grafiskt gränssnitt implementerat i Labview. Nödvändig hårdvara för styrning och kommunikation har konstruerats.Det har behövts tre olika programmeringsspråk för att nå de krav som har ställts på uppgiften, C, Perl och Labview. Microprocessorn i robotbilen har programmerats i C och gör bilen helt autonom, endast beroende av signaler från avståndssensorer.

There are no general working processes that can stand for how all the investment process is preceded in the organization of major Swedish banks. It is not a question of investment process but rather a question of, investment processes. How these investment processes operates depends totally on the type and size of the current investment, which unit that is operating the processes and what situation the bank currently finds itself in. There is a written form that describes how the different processes should be operated and which capital budget models that should be used but the usage of these forms can be questioned.

Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.

The purpose of this essay has been to investigate the research and national initiatives regarding film and Cineliteracy in the Swedish curriculum.The results show that, after all research, national initiatives and the continual clarification from the Swedish National Agency for Education concerning film's place in the Swedish subject, the vision of students cineliteracy not at all obtain an obvious place in the curriculum.The research points out the main causes behind this result to be teachers' lack of expertise and the fact that the formal education for future teachers in the subject still upholds traditional views on the subject of Swedish.The initiative presented in this essay also show lack of continuity, lack of adequate professional development opportunities for teachers and lack of practical guidance manuals to help teachers to develop and educate their pupils in line with current research and visions. .

Studie- och yrkesvägledning i lägre åldrar har blivit ett allt mer aktuellt ämne på senare tid. Ämnet utgör grunden för denna studie, som syftar till att visa små barns egna perspektiv när det gäller deras upplevelse av karriär. Studien består av tio intervjuer med barn i 4-6 års ålder och resultatet visar att barnen har stor medvetenhet när det gäller karriär. Barnen kan berätta om vad ett arbete är, hur man får ett jobb, vilka som arbetar m.m., vilket analyseras utifrån begreppen self-concept, circumscription och images of occupations samt utifrån tidigare forskning. Några slutsatser som dras är att barnen till övervägande del kopplar arbete till föräldrarna, att de inte ser några begränsningar vad gäller könsroller samt att alla barnen anger realistiska yrkesaspirationer..

For nearly twenty years people have been talking about Product models, but given that the building industry is so conservative, it is hard to implement new working methods. Product models are these days known as Building Information Modeling, BIM. People often say they work with BIM but they often forget the most important part, the information. A 3D model should be linked with characteristics and information. Information that can be invaluable for the facility manager.We have a vision that in the best of worlds the facility manager would be able to "walk" into the model and see what kind of installations are inside the wall or in the roof.

This report is the result of several interviews of employees within the field of pedagogy. The background behind this report is my period as a trainee in one of the daily activities in Malmo. In daily activities the employers gets training, education and guidance in Marte meo, which is funded by public finances. The method, which this study focuses upon is called Marte meo. It is a method of communicating and developing the means for the participants to evolve their skills in communicating and increase self esteem.

Concrete floors have traditionally had no problems with annoying vibrations. However with the demand for larger spans the floors need to be made more slender with a higher degree of utilization and lower mass. Therefore new floors may have problems with vibration serviceability. This thesis studies the vibration characteristics of hollow core slabs. The analysis was made in the finite element program Ansys. The hollow core slab was subjected to a varying force simulating one person walking across the slab.

Almost every company sooner or later ends up in a more or less difficult economical situation. The reason for the economical crisis varies for each individual case but common for them all is that it is the management group that has failed in their work to guide the organisation to avoid a negative result. The next common denominator is that it is the management group that has to handle the changes in the company's environment and lead the company out of the crisis. But how can they do this and take decisions in a rational and effective way and is there warnings signals that the management group missed before the crisis was a fact? This is some of the questions that this study is going to discuss and analyze. The aim of the study is from a management perspective chart the strategic work of the company's management work when handling an economical crisis.

This thesis examines the legal boundaries of third-party use of trademarks in the European customized clothing market. The purpose is to determine under what circumstances third parties may legally modify and sell trademarked apparel without infringing on trademark rights. The study employs a legal dogmatic method, analyzing EU trademark law, case law, and legal doctrine to clarify the scope of exclusive rights and their limitations. By analyzing key EU case law, the study further illustrates how the legal framework has been interpreted and applied in cases concerning third-party trademark use. Given the increasing demand for customized fashion and the rise of new business models in the clothing industry, this topic holds significant legal and economic relevance. Additionally, Schumpeter?s theory of creative destruction provides a theoretical perspective on how trademark restrictions impact innovation and market competition.

Our paper is targeting mainly students, but also all other people interested in social work with children. The purpose of our study was to investigate how the social workers experience and handle their work with children, who have been exposed to sexual abuse, and what kind of support and guidance the social workers are offered, in order to handle their working situation. We chose to perform a qualitative study, by the use of interviews, since we found it to be the most appropriate way to gather the information. Our conclusion is that the work with these issues is emotionally burdensome and requires a great commitment, however it is essential for the social workers to maintain a certain distance to their work, in order not to influence their personal lives. It is through experience and knowledge that the social workers learn how to handle their working situation.

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.

It is through experience and knowledge that the social workers learn how to handle their working situation. We also learned that although the work with sexual abuse against children gave birth to different emotions of the social worker, the social workers feel satisfaction with their work, by helping the exposed children. We hope that our paper will inspire and encourage to further studies in the area, since there is still much to be explored. .
