This project was led on behalf of Bombardier Transportation in Västerås, Sweden, incollaboration with KTH Stockholm and EPFL Lausanne. This project is connected to thedevelopment of a new and simplified tilt system for rail vehicles.Growing competition from other means of transportation has forced railway companiesthroughout the world to search for increased performances.Travelling time is the mostobvious performance indicator that may be improved by introducing high-speed trains.They require very large curve radii and long transitions curves not to impairridecomfort, another performance indicator. Building new tracks adapted to high speedtrains is very costly and can only be justified where the passenger base is large.Trains with the capability to tilt the carbodies inwards the curve is a more cost efficientalternative. The tilt inwards reduces thelateral force felt by the passengers allowing thetrain to pass curves at enhanced speed with maintained ride comfort but increases thefrequency ofmotion sickness.The benefits of tilting trains are improved speed capability in curves and enhancedpassengers comfort, but at higher buying and maintenance cost. As the conventionaltrains increase their speed in curves, the performance advantage of tilting trains isreduced while their prize is still kept significantly higher and constant.

In the last decades, high speed cutting has become an attractive technology in the wood industry. The possibility of reducing global costs in addiction with an increase in productivity, were the main reasons for the enlargement of the use of this technology. As usual, these advantages are accompanied by disadvantages that should be carefully analyzed. If on the one hand cutting forces are reduced with increasing cutting speeds, on the other hand, the centrifugal forces affecting the tool are higher. Exposed to such high loads, there is a considerable risk of tool failure that embeds hazards for both machine and workers.

The aim of this work is to take the first step into a development process, with the intention to find a way of making prehistoric soil fertility a variable in archaeological landscape analysis. A pilot study is performed on the Mälar basin area, where four topographical and geological factors are reclassified and then combined, resulting in a map which expresses a relative indication of agriculture potential. The map is then compared to the distribution of Migration Period graves and gold finds. This, however, does not mean that the technique is tied to a certain prehistoric period. Because the work is intrinsically experimental, the technique as a whole is finally discussed and evaluated, and suggestions of improvements and further studies are made..

In this study the semi structured interview method was used to explore what kind of knowledge one In State Authority: The Migration Board, and three Non Governmental Organisations: Red Cross, Save the Children and ISS- International Social Service have about the situation for separated children. Another purpose in this study was to explore if people who are close to the children are working for the best of the children and if their cases were treated with legal security. The result shows that the children?s cases are not treated with legal security and some of the children suffer psychologically from separations from the families and other children need new families because they were maltreated. The result also shows that there are signs that separated children are discriminated compared to children with a Swedish background..

Syftet med examensarbetet har varit att undersöka om Mt Memotekniks produkter uppfyller ISO/IEC 11801:2 standarden, eller om de med hjälp av kondensatorer kan klara kraven för överhörningar. Vi har även jämfört deras produkter med AMP?s Keystone jack som redan klarar kraven för Cat 6 standarden. Memoteknik tillverkar en kretskortsprodukt som består av nätverksmoduler för Ethernet. Dessa kabelsystem skall uppfylla en viss standard för kategori 6.

The population of seatrout and salmon are threatened by over-fishing in the sea and loss of spawning and growing habitats caused by logging activities in many swedish rivers. The knowledge of the spawning migration and the habitat use of the seatrouts and salmon are limited. This study analyse the upstream spawning migration of Atlantic salmon and sea-running brown trouts from the lower part of the rivers to their spawning sites in the rivers Vindelälven and Piteälven. A knowledge about the distribution of spawning sites in the rivers will help these fish population in future restoration programs. In the fishladder at Norrfors in the river Umeälven were 29 sea trout and 20 salmon radio tagged and subsequently released and followed during their spawning migration upstream Vindelälven. They were tracked on their position in the river once a week.

The aim for this bachelor thesis is to find an answer for the placement of Migration and Vendel period graves on preexisting house constructions in Sweden. The reason behind these graves being built on their respective places will be analyzed, discussed and compared with similar finds in Scandinavia, where a wide contact net had been established during this time. Different kinds of social and religious meanings and functions with the grave mounds will also be taken into consideration during the discussion and analysis. The actual findings in the graves will be not be a part of this thesis, as the aim is to focus more on the grave itself as a cultural and social symbol for the people, and the values it had, during the time period it was built..

Transmission of digital signals is today more frequently used than transmission of analog signals. One reason for this is that a digital signal is less sensitive to noise than an analog, another reason is that almost all signals today are handled in a digital format. This thesis describes the development of a system that receives digital video signals through FireWire. The standard for FireWire, which is a high performance serial bus, is under development. Today the standard of the bus supports transmission of data with a speed of up to 400 Mbit/s.

A new theory for predicting the windprofile over a canopy has been evaluated. The theory was first presented by Harman and Finnigan (2007). The theory relies on the forming of a mixing-layer above the canopy, due to different mean wind in and above the canopy. Characteristics from both mixing-layer and Monin Obukhov similarity theory have been used to develop the governingequations that give the wind profile. The theory has been used to calculate wind profiles for sixdifferent atmospheric stabilities.

Bakgrund: Migration är ett vanligt förekommande fenomen idag vare sig den är ofrivillig eller frivillig. Mycket forskning har gjorts om den ofrivilliga flyktingmigrationen men ytterst lite forskning har fokuserat på den frivilliga migrationen, då i synnerhet gällande högutbildade individer med special kompetens. Avgränsningar: Vi har begränsat oss till att studera de mer rationella orsakerna till inflödet av utländsk kompetens, vilka anses vara lättare för en stat att påverka. Vidare så har vi fokuserat oss mot de individer som anses vara högutbildade eller inneha en speciell eftertraktad kompetens. Studien är också begränsad till att studera migration av högutbildad arbetskraft mellan i-länder.

 The 1st of July 2006 Sweden made a change of authorities in the system concerning the reception of separated asylum seeking children. Prior to the change, the Swedish Board of Migration was held completely responsible for the reception of these children, who arrives in Sweden without their parents or any other relatives to care for them. Since the alteration of the law (1994:137) the responsibility for the housing of these children now lies within the Swedish municipalities, while the Board of Migration still handles their legal commissions. The change was intended to fundamentally improve the conditions under which these children were taken care of. However the implementation took a severe wrong turn when the municipalities weren't prepared for their new responsibilities and the immediate result was alarming. This qualitative study is based upon interviews with the people responsible for the reception of the separated asylum seeking children in the municipalities of Kronobergs County, as well as one of the two people in charge of the new system at the Swedish Board of Migration.

In this study the spawning migration activity, habitat choice (depth and temperature), foraging activity, duration of stay in the spawning site and homing-behavior was studied for anadromous pike (Esox lucius) in the wetland Österby myr, Gotland.The spawning migration was concentrated to dusk and dawn, a homing behavior was confirmed and there was no significant difference between sexes with respect to duration of stay. A difference in habitat choice and small variation in foraging activity between individuals was established..

This essay focuses on the Sweden Democrat?s migration policy and its evolution from 1989 up until today. The purpose of this study is to longitudinally examine the party's migration policy proposals to see if, and how, the political ideas have changed over time. Idea analysis has been used as method, and the texts have been analyzed by using three dimensions. Depending on the outcome in the three dimensions, one out of eight political types is possible.

During cold winter days it is likely that people in buildings with older windows or high glass facades experience thermal discomfort due to cold air down draughts. Earlier work has been aimed at finding analytical methods to predict the speed of the airflow in a room and in practice heating appliances are often placed beneath the windows to reduce the draught along the floor. In a study from 2012 Mohammad Parchami developed a method for estimating the required heating power to counteract the downdraught with such heating appliances. In this study, Computational Fluid Dynamics (CFD) was used to evaluate the usefulness of Parchami?s method and also to examine the potential of adapting the depth of the inward window sill as a means of decreasing the down draught.

The purpose of this study was to analyze the level of the uniform way of interpretation from the Swedish asylum officers at the Swedish Migration Board, of asylum investigations for asylum seekers who claim sexual orientation as reason of refuge. The interviews with the officers were analyzed in relation to the policy document with investigation- guidelines and methodology.The results of the study showed that there was a uniform way to conduct asylum investigations and interpret the policy document, this despite that the document was found to be ambiguous in certain aspects. The uniform interpretation of the asylum officers was explained by the knowledge and understanding that exists within institutional organizations. This because the asylum officers at the Swedish Migration Board might have similar experience, knowledge and also the demands related to asylum investigations.The uniform interpretation demonstrated a strong similar common understanding of investigative work within the agency. This suggests a certainty that the investigations are carried out in a similar way regardless of which asylum officer within the institution conducting the investigation which indicates a well-functioning ?rule of law? for the asylum seekers. .
