In this report presents a thesis by Frida Altskog performed in collaboration with Askersunds Kakelmakeri. The project?s goal has been to produce a ceramic ledge after the company?s specifications. The company?s desire and production facilities have been in focus.

Normally the operational amplifier is used as a component in active filter design. The goal for future components in filter design is large bandwith and the use of low supply voltages. The use of current-mode instead of voltage-mode circuits gets a step closer to the required performance. A component that use current as the signal conveying part is the current conveyor. In this report a comparative study between two current conveyor structures of second generation (CCII) is performed.

To enjoy the richness of the grazing cows and high yield during the summers, even during the winter, cheese has been the way to store milk for thousands of years. Nowadays yield is high all year around and the cheese production is possible during all seasons. The aim of this paper is to investi-gate how and why the seasons influence taste and texture of pressed and ripened cheese. Milk is composed of proteins, fat, lactose and water but contains also a lot of vitamins. The quality of milk is very important for the final constitution of cheese.

The Swedish school law says that students who need special education should have all the support they need to reach the qualification that is set up. The arrangements have to be written down in an Individual education plan (IEP). Before the IEP is set up there has to be an investigation about what kind of support and measures the student needs to reach the qualification that is set up. The aim of this study is to examine student?s participation in school and in the progress with their own IEP.I have accomplished a qualitative study by interviewing eight students during the letter part in the nine-year school.

The purpose of this study is to analyze and understand how music festivals in Sweden are marketed today and the changes that will and may occur in the future. Music festivals are a common phenomenon in Sweden today and since most of them only are arranged once a year it gives the marketing of them a special character. Therefore I find it interesting to look at how the development of the Internet will change the marketing of music festivals. This study is based on a qualitative method where I have performed eight interviews with people who have given me their thoughts about this subject. The gathered material and my conclusions of this study are presented in chapter 4 and 5 and for further knowledge about this I recommend you to take a closer look at those chapters..

On a request from the water sewage plant Gryaab in Gothenburg a power quality survey was performed. The voltages and currents have continuously been sampled in the incoming 10 kV substation HSP01 from April-August 2008. Power quality measurements were also performed in Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of the induction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps to the plant. The reason for the latter measurement was due to registered negative transients each time the motor was connected to the grid. The cause of the transients could be explained by the coupling in the substation, the ageing of the motor which could result in damage of the bearings or resonance in the motor circuit which amplifies high frequency harmonics.

The aim of this work is to take the first step into a development process, with the intention to find a way of making prehistoric soil fertility a variable in archaeological landscape analysis. A pilot study is performed on the Mälar basin area, where four topographical and geological factors are reclassified and then combined, resulting in a map which expresses a relative indication of agriculture potential. The map is then compared to the distribution of Migration Period graves and gold finds. This, however, does not mean that the technique is tied to a certain prehistoric period. Because the work is intrinsically experimental, the technique as a whole is finally discussed and evaluated, and suggestions of improvements and further studies are made..

A case study of professional interaction designers' usage of design materials was conducted. Five interviews were performed in order to gain insight in the systems used by designers, how these work, how they collaborate within them, and what they think of recent research about them. Design studios allow collaboration for several users at once. Digital material (mockups, pictures, etc.) are commonly used, but needs to be made analog, e.g. printed, to be usable in the design studio environment.

The purpose of this thesis is to highlight the work with line extensions by companies in the media industry. To obtain this purpose a case study was performed to learn about Norrbottens Media?s actions regarding their new launch of the magazine Extra. Information was gathered through an interview and media observations and was analyzed and compared to previous studies on the subject. Results of this case study show that the main reasons for the company?s line extension were new trends on the market and that the company had unexploited recourses to make use of.

In this essay, I explore the history of the ideas that have shaped the profession of landscape architecture, in a Swedish context. To this purpose, I have sampled the professional debate on landscape architecture at four points in time. These are the years around 1890, 1930, 1970 and 2010. Drawing on G N Brandt (1920), I make the distinction between two arguably crucial approaches, i . e., naturalism and formalism. By identifying these perspectives, and by dividing the arguments of each time period according to this classification, I am able to compare the course of the debate over time. I take on the task through hermeneutics.

A pupil with ADHD is constantly getting new impulses and is unable to focus and remain concentration on their task at school. When the pupil loses concentration he or she can often be loud and thereby disturbing all the other pupils in the classroom. One of the reasons for losing their concentration is that these pupils got poor working memory. A recently study shows that working memory can be improved by playing and practice music.A theory that all people have a multiple intelligence that emerges from learning is a part of this study because school should encourage all children and ensure their individual learning. Multiple intelligences means that each person learns in different ways, for example through the musical intelligence that this essay partly focuses on.

This study examines work relations on a real estate agency. My interest is to examine how real estate agents apprehend their work relations, and how a recession can affect these relations. Previous research shows that the occurrence of competition in groups decreases the motivation to cooperate. A different research illustrates that reward interdependence is important to performance, and that task interdependence drives observed cooperative behavior. The study contained six interviews with real estate agents working on commission.
