A wastewater treatment plant has the task to refine the wastewater from substances that should not be released into the environment. The decomposition process can, in a simple way, be described as follows: micro-organisms breathe oxygen and eat unwanted substances. The environment in which the micro-organism lives is known as sludge and the correct amount of oxygen available in the sludge is important for the decomposition to be effective. The oxygenation of the sludge alone stands for about 30% of the plant?s energy consumption.

The aim of this paper is to examine how confidence in co-operative behaviour of partner is reached in a relationship between an entrepreneur and a venture capitalist. A case study has been conducted on a Swedish football club that has involved venture capital in order to develop the organization. The paper presents a theoretical approach which draws on a control model of interorganizational relationships developed by Dekker (2004) and a model developed by Shepherd & Zacharakis (2001) illustrating how control, trust and confidence is reached in a venture capitalist-entrepreneur relationship. The relationship between the football club and the venture capitalist can simultaneously be seen as an interorganizational relationship and a relationship between an entrepreneur and a venture capitalist. Because of the complexity of the relationship, different control problems prevail.

The aim of this thesis is to find a statistical model that sort logs according to a predicted modulus of elasticity on the sawn boards. The input parameters for the model are X-ray variables from an X-ray scanner. For some of the log classes sawn at the sawmill it is desirable to have a narrow distribution of modulus of elasticity on the sawn boards. 250 pine logs from five different diameter classes were numbered and followed through the sawmill process. Log data were collected from X-ray and 3-D scanners in the log intake.

Teachers in social sciences have a broad subject field to base their education on. This term paper examines, thru interviews, which factors that have an influence on the subjects contents in the A course of Social Sciences at Swedish high schools. Having interviewed four active teachers at three different schools, it shows that control documents like subject- and national curricula have little to say about what kind of subject that should been taught. Teachers seem rather to rely on local collegiate consensus, the textbook, locally prepared control documents, and adjusting to program directions while choosing material. In the final discussion the risk of structuring the subject around the text book is being investigated, along the fact that new locally control documents need to be written even for basic planning structures.

Background: Sleep is the most important human recovery process and research supports assumptions that sleep is an important component in the healing process. Lack of sleep can be the onset of certain diseases such as diabetes, hypertension and cardiovascular disease. Sleep is an integral part of basic nursing. It is important for nurses in hospitals to form a correct understanding of the patients? sleep since they among other things are responsible for administering ad lib hypnotic medication.

Every tenth year a financial crisis tend to interfere with an economy. Price bubbles with an accompanying market plunge are therefore not a new phenomenon. Such market disruptions have been causing problems for centuries, as history has a tendency to repeat itself. The intention with this study is to learn more about the bubble phenomenon and increase the knowledge in this area in order to, if possible, prevent such a thing from happening again. The purpose of the essay is to identify factors that significantly affected the development of the so called IT-bubble in Sweden and Finland during the years of 1995-2000.

One of the main objectives of all food production is to produce foods that can safely beconsumed without fear of being sick. Despite this hundreds of people are affected in Sweden offood poisoning almost every day. Most cases are caused by a small group of so-called pathogenicmicroorganisms. The most frequently affected are the small children, the elderly, persons withreduced resistance and pregnant. The reasons behind the food poisoning are often ignorance andlack of food hygiene.

The goal of this project was to make the requirement process at the Swedish Coastguard more effective. The first step to achieve this was done by locating bottle necks in the process with value stream mapping method. The result of this study showed that the biggest restriction in the requirement process was while examining older requirement documents to understand what elements were suitable for the particular project. This was followed by a study of literature, interviews and theory of Lean Production with the ambition to investigate how the requirement process was handled on other companies and how to improve the process on the Swedish coast guard. This led to a number of potential enhancements of the process which later was evaluated. Requirements written by different people in different organizations were analyzed in order to sort out if there were some similarities? which could be used as standard elements in a future standardization of the process.

This essay discusses children?s rights and control and system of rules in HVB-homes that provide treatment for adolescences with drug abuse prob­lems or criminal behavior. The results of this study are based on interviews with four persons working in managerial positions on different HVB-homes and shows the difficulties of having a children?s rights perspective in a con­text where a higher level of control is necessary to protect the best interest of the child. The study suggests that the question of balance between children?s right and the need for controlling system of rules needs to be fur­ther dis­cussed to improve, and as far as possible guarantee that these adoles­cence receive best possible care and do not suffer unfair restrictions on liber­ties..

This report describes the manufacture and control of a flying platform. The report describes the basic and fundamental theories required to get the platform flying.

Here is presented the result and discussion of a survey concerning the psychosocial environment in a school in the vicinity of Stockholm. The theoretical background of this study was the model of demand-control by Theorell, and various aspects of stress by Frankenhauser and Ödman. The survey was constituted of an inquiry form which was handed out to six different classes at the school. A total of 86 students filled in the form, and their answers were treated with standard statistical procedures to reveal the results. The inquiry form was made up by five parts; one that concerned the background of the respondent, one that reflected the psychosocial health and stress level and three parts that concerned discrimination, victimization and school democracy.

This paper is a statistical examination about how the European Parliament views questions about equality between women and men. It focuses on how the members understand gender equality depending on ideological standpoint, nationality and gender. In other words, it focuses on whether the politicians have different point of views depending on which parliamentary political group they belong to, which member state they are coming from or which gender (man/woman) they have.Equality between women and men is a complex problem. This paper is concentrating on two questions; the problem about setting up a European gender institute and the problem about gender mainstreaming.The examination, which is a statistical examination about how politicians were voting in both questions, shows that all variables, ideological standpoint, nationality and gender, are determining factors for their voting behaviour in questions about gender equality. Ideological standpoint is the most important variable, second in place is gender and the least important factor is nationality..

This thesis is divided in to two different parts. The first part includes examination of the measurementsystem of an industrial robot using a resolver sensor. The main focus is on methods for suppressing noise in the angularvelocity signal without increasing timedelay. Five different methods are investigated. Three of these are based on oversampling: burstsamplingmethod, meanvaluemethod and correlationmethod.
