The problem of separating a non-rectangular foreground image from a background image is a classical problem in image processing and analysis, known as matting or keying. A common example is a film frame where an actor is extracted from the background to later be placed on a different background. Compositing of these objects against a new background is one of the most common operations in the creation of visual effects. When the original background is of non-constant color the matting becomes an under determined problem, for which a unique solution cannot be found. This thesis describes a framework for computing mattes from images with backgrounds of non-constant color, using Bayesian statistics.

The purpose with the study is to see how middle managers in communal elderly care looks at the implementation of the salutogenic way of working in their operations. And how it affects the middle managers working situation. We studied which scope of actions middle managers has in the salutogenic way of working. We had previous knowledge that the salutogenic working way is an ongoing work of development in several communes, and therefore we chose to study in a profound way how this work of development affects the middle managers working situation. To reach a deeper knowledge about how the salutogenic way of working affects the middle managers working situation we conducted a qualitative study with been seven semi-structured interviews with middle managers in different geographical communes.

Den tilltagande betydelsen av att skydda civilbefolkningen i fredsbevarande operationer har genomgått en påtaglig utveckling, följt av delade meningar om vad säkerhet innebär. Jag framhåller att utvecklingen skall förstås som specifikt problematisk i den meningen att kvinnor har blivit alltmer utsatta i konflikter, vilket samtidigt beskrivs som ett understuderat förhållande inom forskningsområdet. Med utgångspunkt i Feminist Security Theory syftar den här uppsatsen till att studera förekomsten av ett feministiskt perspektiv i internationell säkerhetspolitik. I samband med antagandet av UNSCR 1325 om kvinnor, fred och säkerhet år 2000 beskrevs för första gången kvinnorsställning i konflikter i form av en säkerhetsfråga och därmed inte längre enbart inkluderat i FN:s mänskliga rättigheter. Således bereddes utrymmeför nya möjligheter att hantera säkerhetsutmaningar på.

The development of farm-operated biogas plants in Sweden is increasing. This study investigates the process that firms go through in developing such ventures. The aim is to identify obstacles and opportunities that individual farmers have encountered during the implementation process, and through a comparative analysis find similarities and differences between cases. The overall goal is to increase understanding of the factors that influence farmers? development of farm-based biogas production, and more specifically, explore opportunities for support organizations to contribute to the innovation process. Findings indicate that the implementation process has changed over time.

In the summer of 2009 the High Line opened in New York, a park built on an out-of use elevated rail viaduct. The park meanders its way through the buildings and allows the visitor to see the city from a totally different perspecive than we are used to.I have made a Design proposal in Eriksdalslunden, Stockholm, with inspiration from the High Line. The proposal is based on design ideas of a park I logically call the Low Line, as the place isn't elevated as in New York, but lowered. The two places have some similarities, mainly the strong urban identity and the tracks crossing both areas. They also have very obvious differences, above all the fact that Eriksdalslunden is situated in a swale and is defined in a third dimension by the high bridges that crosses the area.The High Line is designed by James Corner Field Operations, and they have been working using their motto 'Keep it Simple, Keep it Wild, Keep it Quiet and Keep it Slow' during the whole process, words that normally aren't associated to Manhattan.

AbstractThis study aims to investigate the applicability of well-recognized supply chain strategies based on product characteristics. Choosing the right supply chain strategy can be the difference between winner and loser in today?s competitive climate and science offers several recommendations as to which aspects that should be considered. Fisher (1997) and Christopher and Towill (2002) suggest that supply chain strategies should be based on what kind of product the company is handling and that, in order to know which strategy is the most appropriate, the products must be categorized. Some criteria developed for the categorization are lead time, forecast in demand and profit margin.

The purpose of this study was to examine social workers working process in social assistance with focus on the child´s perspective. We were interested in learning about the existence of variations in approach and attitude between two municipalities. Question to be answered about what methods and approaches used by social workers to include the child´s perspective in the process of social assistance. Another question to be answered about what the manner in which social workers took into account the child´s perspective when the families apply for social assistance in relation to the operations and requirement. To fulfill the purpose, qualitative methods were used.

Throughout the history, the theories which have shaped our cities have varied from time to time. We have gone from a city development characterized by spontaneousness, where commerce and people side by side shared the space, into a function-based planning where people and functions are being increasingly separated. Regardless the forms of planning the city design causes implications for those who live there when the physical environment controls were we live, work and meet. In today's society where `sustainability ' has become a watchword the current community planning needs to be questioned so we, in the best possible way, can meet future changes. Searching for new planning strategies is part of this and in this essay the term `mixed-use´ will be investigated and analyzed in terms of its social aspects.

This bachelor thesis is about civilian marching bands in the province Värmland industrial communities, with a focus on Degerfors, Edsvalla, Gruvön, Nors, Slottsbron, and Vålberg bands. Degerfors, Gruvön, and Slottsbron bands are three corps that still operates concerts and performances. The other three unions are defunct.In Värmland, there were many mills that were operating well into the 1900s, roughly speaking there were about 25 mills in various industrial areas. These mills had operations in glass, iron, and paper, each user had a band at least a brass sextet and today there are only eight bands left in Värmland. Bofors in Karlskoga, Charlottenberg, Degerfors, Dejefors, Gruvöns in Grums, Hagfors, Skoghall, and Slottsbron bands.What is the reason that so many bands have disappeared? To answer the question I have investigated the importance of four factors have had for the unions: finance, recruitment collaboration with the music and arts, as well as cooperation with educational associations.The results show a marked reduction in civil bands, from about 25 corps to eight corps today.

Leverage buyout?s is an opportunity for companies, who can strengthen its market position by expanding its operations, and it add?s value to the company. At every LBO, copmanies make different values of the target company to finally come upp to a final bid. The final bid may in many cases be made of a surplus value, which is the differens between the value of the net-assets and the final bid. This we call goodwill and it has been a target in many discussions.

This project has as main goal to study the influence of the coating thickness, deposited by arc-PVD- technology, on the wear resistance of coated cemented carbide inserts in three different turning operations. An additional effort has also been made to develop a new test method for evaluating flank wear resistance. Three different coating types (Coating A, Coating B and Coating C) have been studied in three distinctive thicknesses (2, 4 and 6 µm) for each type. For two of the coating types (Coating A and B) special studies has been done with the thickest coating, creating two additional coating versions of the thickest coating, by changing various deposition parameters, with the aim to enhance the cohesive properties of the coating and lower the residual stresses at the cutting edge. The results show increased crater wear resistance with increased coating thickness for all coating types, but the amount of increase changes with coating type (Coating A>B>C).

Result: The core category ?From uncertainty to relief with newly acquired experience? could summarize the result of this interview study.

The environmental work in Sweden has developed a lot over the past fifty years. Today, most companies have some kind of environmental work. Environmental activities are regulated by the Environmental Code, which applies in parallel with other laws. This report is an environmental review for Bräcke Diakoni. The report aims to find out how much environmental impact Bräcke Diakoni has.

Free play is a term that often common in educational activities. The definition of the term is difficult, but it is about the children themselves decides the scope, content and process in their play. On an after-school, this may mean that it is the children are given the opportunity to freely choose their own activity in the leisure constraints. Free play can be an alternative to other, more controlled activities where adults control framework. The purpose of this study is to investigate the variations in how some children perceive and experience the phenomenon of free play in the after-school and how the children perceive the teacher´s role in the free game.

In Trollhättan municipality approximately 700 school bus stops are in service. To ensure high quality of the performance of school bus operations, with focus on traffic safety, it was decided to conduct a survey of bus stops including assessments of risks.This master thesis aims to identify the factors affecting road safety at bus stops and pedestrian connections, and to conduct an inventory and analysis of selected sites in Trollhättan municipality. The work also aims to show examples of how risk assessment should be performed in future studies. A risk analysis model provided by the Swedish Transport Administration is supplemented and used in a field study. The risk assessment is based on, inter alia, traffic flow, visibility distance, lighting, speed of traffic and the presence of bus shelter.
