ABB Surge Arrestors in Ludvika have for a long time had a problem to keep the moisture at a steady state in the production of their ZnO-powder, that is used to produce varistors.Some black-box models of the spray drying process have been designed and evaluated to find a solution for the problem. After evaluating the collected data it has been found that variations in the supply voltage causes control difficulties for the operator. A cascade control system was designed, consisting of three PI control loops designed with lambda tuning. The disturbance in the supply voltagewas used as a feed forward in the control system.At the end of the project the control system was installed, and tests were made to verify the functionality of the regulator. It was shown that most of the variations in the moisture of the powder could be eliminated using small resources, through purchase of a process controller and four power meters.

My essay deals with a problem in our society which, in my opinion, has been neglected. Even today in 2011, the quality of schools and preschools is extremely varied. This has been a problem for a long time and not nearly enough attention has been paid to it.In my essay I have tried to understand what it is that causes these differences in quality between preschools. With help from literature and research studies I have examined what quality in preschool really means.My starting point is an account of my own experience at the preschool where I currently work and a description of a study visit I made to another preschool which operates in a very different way to the one where I work. I wanted to investigate what the consequences are for children who grow up attending preschools of different quality.

Introduktion: Trots att kompressionskläder (KK) används brett inom idrotten saknas det klara vetenskapliga belägg för att dessa faktiskt skulle ha en positiv effekt för vältränade idrottare. Det är relativt lite forskning gjord på hur användandet av KK påverkar prestationen vid aerobt arbete. Syfte: Att undersöka huruvida användandet av KK har en positiv inverkan på högintensivt aerobt arbete för idrottare. Metod: En randomiserad cross over design med placebo har använts och 6 vältränade (27 ± 5 år, längd, VO2max 59,0 ± 3,2 ml ? kg-1 min-1) har genomfört tre maximala tester till utmattning på löpband.

This paper studies the option market?s implied dividend as a predictor of future equity market returns. We introduce this variable in the simple total return framework and discuss some complications of using it as a proxy for the expected dividend. We construct some regressions using the price-dividend ratio and the implied dividend growth, and test them on six years worth of data on the EURO STOXX 50-index. The main result is that implied dividend growth exhibits some forecastability over two-year horizons, but that the dataset is too short to draw any definitive conclusions about long-horizon forecastability.

How can man´s place preferences be explained? What aspects influence our experience of place? This essay attempts to define a good place to be drawing from sources of environmental psychology as well as other landscape theories and relating these findings to the landscape architect?s field of work. Physical place properties, like physical elements and their juxtaposition in space are examined in relation to place preferences as well as psychological properties, such as place attachment and place identity due to cultural or social aspects.There are strong cross-cultural similarities in our place preferences but there are also some differences. Natural elements, like trees or water, are widely preferred over man-made ones, like buildings, roads or fences.Man seems to be sensitive for the balance between different place characteristics, like the balance between ?soft?, natural, elements and ?hard? man-made ones or the complexity versus the legibility of place.

Industrialisation, modernisation and urbanisation are common words used to describe an evolving community. General patterns are often linked to the meaning of the above words but can these patterns be applied to individual parishes on the agricultural countryside?The purpose of this study is to seek moving patterns and how they change during the 19th century in the parish of Västra Eneby, municipal of Kinda, Östergötland. The main thesis is that the study will show an increasing intensity of translocations over the parish border towards the end of the 19th century.The study is based on material from Västra Eneby?s church archives to establish statistical data beginning with 1809 and with a sample rate of 10 years, ending with 1909.

The purpose of this thesis was to create a strategic/tactical road access plan. This was done by designing an analytical method which gives the road manager a template to create long-term road access plans. The analytical method will help to identify and appraise roads to be upgraded and give information when it is time for building new roads. The study method involved developing an analytical method. The method was comprised of five main parts: the harvest plan, analysis of the road network, transport costs, quality and storage costs and finally, identification of investment alternatives.

Abstract Youths and adolescents have for a long period of time, and at a high degree, beenabsent from the party political stage. The causes for this have been discussed inthis essay through a quantitative survey made in an upper secondary school class,consisting of some 19 subjects in the municipality of Kalmar. Tied together withrelevant literature and discourse on the subject, the essay has dealt with thepossible societal-, system- and individual barriers for political interest andinvolvement. Central questions for this essay has been for instance; age, gender,social background, geographical domicile, as well as the decline of ideology, theforms of current party politics, political interest, political engagement and soforth. The concluding remarks contain not only a mix of these barriers existing,not exclusively, for young and adolescents but different ground for them as well.On the one hand, there exist barriers which exclude youth from the conventionalpolitical life, but on the other, the more individualised youth of today, prefer to agreater extent not to participate under the conventional circumstances that partypolitics has to offer.

The estimated number of people living in extreme poverty is 1.3 billion and 70% of those are women. The aim of this study is to explain in what ways and why women are regarded as poorer than men.The definition of poverty has expanded and is now multidimensional. In order to answer the aim of this thesis the following dimensions will be included and work as a theory in which the analysis will be structured after. Through a gender perspective, will the role of woman emerge through a multidimensional definition of poverty. If the balance is a negative in these dimensions, the situation for women will worsen and become permanent.

This essay sets out to compare political participation in two e-petition systems: The Malmö initiative in Malmö, Sweden, and Better Reykjavik in Reykjavik, Iceland. The main question of the essay concerns the aggregative and deliberative qualities of the Malmö initiative and Better Reykjavik, as well as the relationship between aggregation and deliberation. This main question is divided into four subqueries that lead the empirical analysis. These are: (1) Which similarities and differences in terms of design are there between the Malmö initiative and Better Reykjavik? (2) To what extent have these systems mobilized an aggregative political participation? (3) What similarities and differences are there concerning aspects of deliberation? and (4) What is the correlation between aggregation and deliberation like in the two e-petition systems?The method in use is a comparative cross-sectional study with a 'most similar research design'.

The purpose of the thesis was to map the hydraulic load on the Knivsta river from stormwater runoff, and build a platform for further studies of pollution loads on the rivers ecosystems. New residential areas are planned to be built in Knivsta municipality and it will have an impact on stormwater flows to Knivsta river. To examine the impact this will have, simulations were made in the area as it stands today and after expansion work. The work includes calculation of flows from the populated areas but also from the catchment area around it consisting of woodlands and fields. Because of expected climatic changes which may affect rainfall, the simulations have been performed with different return periods for rainfall data.

Sweden has a long and extensive wind band tradition. Today the interest for the traditional instruments is decreasing among children and teenagers. What can this be due to? Which conditions are needed for a functional wind band in the future? The purpose of this essay is to find answers to these questions and at the same time shed light on good examples, where the wind band activity works. To be able to answer the questions have I made four interviews with persons who have a big knowledge and interest about the subject.
