The purpose of this thesis for Sapa Heat Transfer is to examine a furnace in which aluminium is pre-heated before hot rolling. The project is modeled in a computer environment in which the air flow in the furnace and the heat transfer to the aluminium solids are included. The computer environment and its governing equations, as well as boundary conditions and generalizations, are presented and explained.The simulations are based on two models. The first model has an asymmetric solid placement, which is how it looks in today's ovens. It is validated against collected data.

My aim is to find out about teachers? perceptions of methods concerning learning and assessment of oral proficiencies. My questions are: What perceptions are there among teachers concerning assessment of oral proficiencies? How do teachers describe their ways of promoting and assessing oral proficiency? In order to answer my questions and obtain data I have accomplished two focus groups interviews with seven language teachers. The result shows that teachers are concerned with several factors regarding assessment of oral proficiency.

This thesis raises the problem with acid mine drainage around the closed mine Finngruvan.The purpose of the investigation was to compare metal content in surface water in the areaand its catchments between year 2010 and 2003, also to make calculation of specific runoffand metal load, furthermore determine the recipients in the area. Surface water samplingwhere preformed at the same place as 2003 and also at a few other places of interest. Adigital elevation file were used in GIS to calculate the area of the watersheds in the region,observations in the field where also made. The collected data were used to make comparisons,calculations and conclusions. The result showed that the surface water 2010 had somewhatlower metal concentrations.

When developing software that is meant to be distributed over several different computers and several different networks while still working together against a common goal there is a challenge in testing how updates within a single component will affect the system as a whole. Even if the performance of that specific component increases that is no guarantee for the increased performance of the entire system. Traditional methods of testing software becomes both hard and tedious when several different machines has to be involved for a single test and all of those machines has to be synchronized as well.This thesis has resulted in an exemplary application suite for testing distributed software. The thesis describes the method used for implementation as well as a description of the actual application suite that was developed. During the development several important factors and improvements for such a system was identified, which are described at the end of the thesis even though some of them never made it into the actual implementation.

BackgroundToday a common approach to solve a complicated problem is to assemble a temporary workforce in order to solve the problem by working together within a project. One of the difficulties with working in projects is to maintain the planned budget. Working hours and costs are often exceeded. Many companies presume that any certain project will succeed, a presumption that leads companies not to anticipate risks involved in a project. In companies today there is seldom time for evaluation or moderation of a project, in order to have time for evaluation there is a great need for an adequate planning of the project.IntentThe intention with this study is to create a model for planning, budgeting and evaluation of projects within consultancy companies.MethodWith the help of interviews and discussions within the group Hamnar och Byggkonstruktioner at Sweco has evidence to present a proposal on planning, budgeting and monitoring been developed.ResultsA model has been developed to ease for consultancy companies to plan, budget, monitor and evaluate projects.

The purpose of this study is to examine the importance of a working laboratory in mathematics education, how it influences students? learning and the confidence the teacher has in the laboratory component. Focus has been placed upon the advantages and disadvantages that could follow in the working method.The method used in this essay is qualitative in order to answer all the questions that arise along the way, and in order to use this method in interviews. The interviews that has taken place has been with five class teachers that are currently teaching at a elementary school between the years of 1-5. The purpose of this study has been answered by using its literature and the qualitative method with the class teachers.The results of the research show that teachers express gratitude towards the method in use for mathematics studies.

AbstractThis study aims to describe and analyze how the 15 municipalities of Västerbotten County consider regional targets of development in their comprehensive plans. The study also investigate if there´s any need of improvements for the consideration of regional targets in comprehensive planning.This paper is based on studies of comprehensive plans in Västerbotten County and on three interviews with employers of different municipalities in the county. An thematic analysis were used to analyze documents and interviews.The result shows that a new comprehensive plan generally takes more consideration to regional targets of development than older plans. The consideration varies a lot between the municipalities of Västerbotten County and it can be explained by many reasons. The informant?s points out that lack of resources- and competence plus a deficient dialog between municipalities and regional organizations are the mainly causes.Keywords; regional development, comprehensive planning, strategy for regional development, regional development program, land-use planning.

The purpose of this examination is to identify how notions of Swedishness is created artistically, and from where these notions come. My method is to make a study on exhibition catalogues on the theme Swedishness/Nordism, with focus on the contemporary Swedish artist Peter Johansson. With a retrospect of his childhood in Dalecarlia, he investigates a Swedish iconography with it?s roots in national romanticism, which for more than one hundred years has been preserved and exploited of the tourist industry to market Sweden. It?s this monotonous iconography that Johansson deconstructs to make it appear like something else ? namely an iconography based on ethnic purity, which pushes away the foreign and protects the own.

This thesis studies path generation for industrial robots of six degrees of freedom. A path is defined by connection of simple geometrical objects like arcs and straight lines. About each point at which the objects connect, a region, henceforth called a zone, is defined in which deviation from the defined path is permitted. The zone allows the robot to follow the path at a constant speed, but the acceleration needed may vary. Some means of calculating the zone path as to make the acceleration continuous will be presented.

Background: At this present moment, one of the largest changes in the Swedish employment market is occurring, as the people born in the 1940's are retiring. The Generation Y, people born in the 1980's, will enter. Will this have an affect on motivation and leadership, and in that case, in what way Aim: The purpose of this essay is to investigate whether or not Generation Y (born in the 1980's) has an effect on the perceptions on how to lead and motivate employees. Based on research and our empirical results from qualitative interviews at one of Sweden's largest banks, our research questions are:1. Are executives' and employees' perceptions regarding Generation Y in line with previous research 2.

Modern air battles are very dynamic and fast, and put extreme pressure on pilots. In some unpredictable situations, like new discovered threats or mission plan deviation because of enemy aircraft, the pilots might need to replan their predefined flight route. This is very difficult, if not impossible, to do since numerous factors affect it. A system that can help the pilots to do such a thing is needed. Previous work in this field has involved methods from artificial intelligence like A*-search.

It often occurs that the spirit regarding the future as a conservator is rather pessimistic. Howcome that there are so few employed conservators, when the need for conservation obviouslyis big? What kind of changes is needed for a better status regarding the conservation?This thesis concerns the development of the field of conservation in Sweden. What havehappened, what will happen and, particularly, what should happen? The information wasgathered from literature studies and interviews during the spring of 2010.

Obesity and overweight is the worst public health related disease today, and it is a constantly increasing problem in societies all over the world. In Sweden the number of overweight persons has been doubled in the last 20 years. Today about 500 000 persons suffer from obesity and overweight.The aim of this study was to investigate obese and overweight people´s thoughts and wishes regarding what support they would like, in order to be able to successfully manage a weightreduction. The study is qualitative and conducted through six interviews, the material was analysed with content analysis. The result of the analysed interviews led to four categories:offered support, wished support, are you strong enough to find support by your own and mental wellbeing.The conclusion of this study is that overweight person?s biggest wish is to get continuous and personal support from the health care system.

The spatial population structure of the saprotrophic basidiomycete Tulostoma brumale was investigated at a site in south eastern Sweden. Sporocarps were mapped and collected, and somatic incompatibility tests between mycelial cultures cultivated from the sporocarps were used to identify genets. Calculations of the size and numbers of genets and their distribution were performed. The spatial distribution of the tested sporocarps and the identified genets are presented graphically in a grid. The total number of identified genets within the investigated area (1210 m2) was 27 based on 48 tested sporocarps.
