In recent years, the Swedish railway track system has been neglected in terms of capacity and maintenance. To adapt the existing system to current traffic load there is a great need for extensive improvement and maintenance. Shortcomings are especially occurring on older embankments running over soft subgrades. To select the most suitable method for reinforcement of the embankment, it is important to evaluate different solutions from a life cycle cost perspective. In long-term perspective, it is often shown that a method with low investment cost causes a higher maintenance cost and a shorter technical lifetime.

GE Healthcare wants to investigate whether additive manufacturing would be an alternative method in their workshops in the Umea? plant. Additive manufacturing is called 3D printing in everyday language and manufactures details by building them up layer by layer in an automated machine. The purpose of this work is therefore to investigate how mature additive manufacturing methods are and how they could be used at GE.The work has been divided into three parts. The first section investigates how additive manufacturing would work in the production workshop at GE.

Nowadays naval units are participating in international missions, where new and in many cases tougher conditions will affect their propulsion. This essay deals with some of the now developed nanostructure coatings and gives a presentation of how the coatings could function on some exposed parts of the naval powertrain. The essay investigates the possibility that the coatings can be used as a protective layer that will reduce or prevent wear on selected parts of the naval powertrains. As a basis for the essay, nanotechnology is described, as well as different reasons that wear occurs and application techniques for coatings The conclusion is that nanostructured coatings can be applied and provide a much better result on hardness and wear resistance as of naval powertrains compared to micro-structural coatings, both for manufacturing and renovation. The essay presents a few examples of the military utility of the nanostructure coatings as well as suggestions for further research..

?Are the headwaters streams at the right position in the map? is a study that has been performed on behalf of Holmen Forest, region Örnsköldsvik. This study will be the basis for deciding if the Hydrology Layer Property map or Holmen Forest map will be used for planning nitrogen fertilization in forestry. The background to this study is that nitrogen fertilization near water will increase the risk of nitrogen leaching out into the water systems, which has a negative impact on the environment. The headstreams positions have been recorded in the field with a GPS and the data analyzed in the geographic information system ArcMap.

Title: The process of gentrification ?the transformation of declined neighbourhoods into attractive ones Gentrification = ?A social process of change where people with high socioeconomic status move into neighbourhoods which traditionally has been dominated by people from the lower classes or from ethnical minorities.? (Nationalencyklopedin 2010).In many cities around the world, disinvested neighbourhoods become the place to be, where everything happens. This usually occurs when different social groups, such as bohemians, homosexuals and artists, move into a declined and disinvested neighbourhood. After a while, people from the middleclass move in to the area due to its increased attractiveness, and start to renovate their properties. This usually leads to higher rents, which force some of the original inhabitants to leave the neighbourhood.

This thesis presents the results from a osteological analysis and a GIS-study aimed to examinedifferences in the located animal bones in different areas of the excavation site of Ajvde.The osteological material came from five excavated square meters on the site and was comparedwith osteological results from other researchers from different areas to create overview and try tosee differences between the areas.The GIS-study took data from all animal bone material excavated on the site, a total of about 2300kilos, and presented them in maps of spatial distribution for each layer (pictures 4, 5, 6 & appendixpicture 1) to see if there were any clusters of activity and changes between the layers. The dating ofthe culture layer and the burial field (pictures 7 & 8) were presented in maps to see if they could becorrelated with what was seen with the animal bones. Pictures of different shorelines were alsopresented (picture 9) to compare with the results that were seen in the changes of animal bones fromdifferent layers.The results of the GIS-study have shown that the activity on the site have moved over time alongthe hight differences of the land. The earlier layers show activity only on the higher elevation butlater moves down, and in the upper layers activity have been all over the excavated area. Clusters ofanimal bones were seen in the so called ?black areas? of the sites (shown in picture 2) but also otherareas contained a lot of animal bones.The results of the osteological analysis have shown that there are differences in what species arefound in different areas.

A Social Enterprise is a business that features a mixture of characteristics that originates from the third and private sector. A general conception of Social Enterprises is that they aim to improve social welfare by the use of sustainable business models. The mixture of social and business features has created ambiguity about how to define Social Enterprises. The purpose of this study is to clarify Swedish Social Enterprises as a phenomenon and to examine antagonism that arises from mixing the two different sets of organisational characteristics. This is achieved by conducting a qualitative study of ten Swedish companies that the market considers to be Social Enterprises.

The high viscosity of barley material makes starch isolation problematical using regular methods established for cereals. An adjusted starch isolation method has been set up for barley, based on fractionation and purification. The focus is on attaining truly representative isolates of six flour samples selected for widely differing characteristics within the research program BarleyFunFood (BFF). Beside establishment of the method, this diploma work aspires to serve the BFF with isolated material of sufficient yield valid for further starch characterisation. A pre study was conducted evaluating available wet mixing equipment, experimental conditions and mode of procedure.

This master thesis deals with two case studies in environmental archaeology and battlefield archaeology focusing on two major events in the late history of the Swedish coastal town Umeå and its nearby village Sävar. Established in the early 1600's, Umeå was known for its export of timber and import of cereals. The town has suffered from numerous fires, the fire in 1888 being the most devastating. Few written records of the town remain from before the 1900's. The latest war in Sweden's history is documented in historical sources and took place at Krutbrånet, Sävar where the Swedish troops suffered defeat against the russian forces in 1809.

To be examined in hospitals can sometimes be perceived aspainful by children. Therefore there is a need for something,which can distract children?s attention from their perceivedpain. During my graduation project, I discovered a designopportunity to work with suspended ceiling systems inexamination rooms, as there is not much to look at whilebeing examined.The result, Twig Ceiling is an interactive nature-inspiredbacklit module with colored LEDs. Twig Ceiling has onelayer of pattern that is visible when the module is not litand the second layer of pattern appears when turning onthe light.

In this degree project we wanted to investigate if there are any possibilities to get a higher income from grain growing by giving the grain to hens instead of selling it. We were also wondering if the manure has any value or if it only cost the egg producer money. If the egg producer cultivate his own grain and is able to store it in layer is there quite much money to earn. Expensive pasture makes it profitability to pay up to 1,35 Swedish crowns for a kilo of wheat. In our calculating we?ve used calculation from the company Lantmännen.

Computer based information systems play an important role in modern military combat vehicles. The crew needs to be able to quickly get information about both the vehicle and its outer surroundings in order to quickly make the correct decisions. In this report, we describe the development of a prototype new information system for the BvS10 vehicle, manufactured by BAE System Hägglunds AB in Örnsköldsvik.An important aspect of the system is the time it takes from the point that the information is generated by the vehicle sensors until it is presented to the user. The system must be able to ensure that it never displays information that is out of date. Thus, it is important to create a layer and component based architecture for the solution, making it possible to control, in detail, the information?s age as it moves through the system.
