This thesis considers the development of the software for an, newly developed, embedded real-time control system, based on a Periferal Interface Controller (PIC). The control system is developed to be used for several different applications. In this thesis work, software for two different applications are developed. The first task is a time controlled system, while the other task is implementation of aPI-/PID-controller. A user interface is also developed and implemented.The time controlled system is an automatic horse feeder, which is used for feeding horses at certain predefined points in time.

What on earth do people see in camping? Why do they choose this compact living in their holiday? All that people in caravans who are put together in a camp site.The purpose of my study was to find out who and wy. My ethnographic study in a camp site with participation observations, interviews and analysis have results in facts that show why.The most common camper is the house owner with average income. And the choice of the camp site depend on the security and the service that the camp site offered. The camp site was controlled and the campers controlled each other.

This thesis includes a description of the project flow for our projects at Semcon. The emphasis is on designing a manual for elMaster Concept.The project flow provides several minor and major elements plotting schedules for this project and the establishment of a manual. When a schedule is drawn, lists and tables with components and connections can be created. This is done to better manage drawings and make changes. These diagrams and tables are used in product manufacturing, testings, controls.

A controlled recording in a studio is the basis of all voice treatment. However, this controlled way of recording voice patients' voices can be questioned. The voice use may be different in a natural environment. In children noise related voice problems are investigated in a study about voice and its development (BUG ? Child voice and noise).

This thesis is a part of the project "Sustainable harvesting and storage of sugar beets, more sugar to practice". The work has included a large part of practical experimental work with weight measurement, graduation and storage planning. The aim of the project is to be able to see whether the cultivars react differently in different storage conditions. The project has included storage under controlled conditions to give as accurate results as possible. To be able to mimic the farmers own preconditions the samples was harvested with a conventional Holmer.This project has two parts, one concerning the nature, time and temperature on storage where a number of different cultivars where investigated during three different recording times, two different temperatures and controlled in a controlled environment.

In Sweden the latest curriculum, Lpo 94 was released in 1994. This document revolutionized the teaching profession. The school system was changed from a governmental control into a communal control. The earlier curriculums were controlled by rules; Lpo 94 is controlled by aims. This has led to a big spectrum of teaching styles which all of them agrees with the Lpo 94.Our purpose with this report is to illustrate two different leadershipstyles regarding the subject Swedish.

The aim of this thesis is to investigate indexing consistency in LIBRIS, a Swedish national union catalogue, where searches can be carried out among almost five million titles. To calculate consistency, indexing terms of translations and indexing terms of documents in their original language have been compared. I have used a total of 100 such pairs in the study. There is a lot of different methods that can be used when consistency is calculated, in this study Hoopers and Rollings methods have been used since they are two of the most commonly methods used and also have the advantage of being fairly simple to use and understand. In the thesis, differences in consistency between indexing terms consisting of names and general indexing terms and differences in consistency between controlled indexing terms and uncontrolled indexing terms are also compared.

The non-governmental organization Gram Vikas primary concern is to establish clean water in remote areas inhabited by often aggrieved tribals and low caste communities. Gram Vikas? slogan is Water for dignity. It refers to that everybody, regardless whereupon the social ladder you are, are entitled to the most fundamental elements for a dignified life. The purpose of this essay is to highlight the factors that are important for a shift to a more equal and sustainable living.

This project is part of the course MF10YX, introductory mechatronics. The purpose of theproject is to integrate modules from the group members previous specializations into amechatronic system in the form of a self-balancing robot. The prototype ?Charlie? should be ableto race along a 10 - 30 m line. It should be able to start manually and autonomously detect andstop after the finishing line.

This report discusses the development of an autonomous system that can travel a distance of atleast 30 meters on two wheels. The system, the robot, detects black lines and stops if one isdetected. A remote control can be used to start and stop the robot. The robot is constructed ofmainly steel with smaller, more detailed, parts in plastic. A significant amout of time has beenused to enable the robot to balance on its own.

The system tungsten-oxygen has potential of being suitable for decorative coatings since ceramic coatings are often hard and wear resistant, and since modulations in oxygen content or incorporation of small ions could give bright colours. The aim of this report was to investigate the relationship between process parameters and  the properties of the films, with the wear resistance being of special interest.Samples with tungsten to oxygen ratios in the range of 100:0 to 25:75 at% were made using reactive sputter deposition, either with constant gas flow, or gas flow controlled by optical emission of the plasma. The hysteresis of the system, which means that a certain gas flow will cause different pressure and/or target voltage depending on in what way the flow is reached, makes it interesting to control the process where the system makes the steep change from metallic tungsten to ceramic tungsten oxide. This is difficult and thus requires precise control equipment.The samples were analysed using X-ray diffraction, X-ray photoelectron spectroscopy and an empirical wear test suitable for small components like cell phone cover for example, in order to characterize the structure, composition and wear resistance of the coatings. The results could be divided into three groups: (I) tungsten-like, with very low oxygen content; (II) mixed phase and (III) tungsten oxide like, with oxygen content close to 75 at%.

This master thesis in energy optimization was made during the autumn of 2006 at Käppala wastewater treatment plant in Lidingö, Stockholm. A preceding thesis, where all electricity consumption was mapped, showed that the aeration in the biological treatment is the single largest consumer in the plant, and it is therefore of interest to reduce this cost. The oxygen control strategy used at Käppala WWTP is working well from a nutrient removal point of view, but not from an economic one. The last aerobic zones have a very low oxygen consumption during low loading periods which give rise to enhanced dissolved oxygen concentrations with excessive costs and reduced denitrification as a result. But also during periods of normal loading unnecessary high oxygen concentration are sometimes given.By modifying the aeration control strategy three full-scale experiments have been made, with the intention to reduce the air consumption.

This thesis is about a part of the marquetrytechnique, scorching. Scorching is made by heating up something, put a veneer into the heated substance and make a controlled burning. This technique is old but still used today and have according to me great potential for development. In my work I wanted to give the scorching greater room then I earlier have seen. I wanted the scorching to be the dominant ingredient for a decorative element in a piece of furniture or an interior.

Dagkirurgi verksamheten ökar och det pågår en debatt om vilken anestesiform som är mest lämpad för denna verksamhet. Snabb återhämtning, god kvalitet, kostnadseffektivitet och få biverkningar är målen för att få patienten att kunna gå hem samma dag. En kvantitativ studie med en enkät framkonstruerad för studiens syfte utfördes. Syftet med studien var att undersöka vad om avgör om en patient skrivs ut tidigt eller sent vid dagkirurgi med övningsmetod intravenös anestesi Target Controlled Infusion TCI eller Total Intraveös Anestesi TIVA. 20 stycken patienter på en dagkirurgisk avdelning observerades postoperativt av ansvarig sjuksköterska, som fyllde i frågorna i enkäten.

The aim of this paper is to compare subject headings by the authors of the work and those administrated by professional indexers. The empirical setting for the study lies within the sociological discipline. The questions asked are:? What overall similarities and differences between subject headings administrated by authors versus indexers can we find?? What qualitative advantages and disadvantages can we establish between subject headings generated by natural language versus controlled vocabularies?Subject headings in the Swedish national library catalogue Libris and in five Swedish universities platforms for academic publishing are studied and compared. Today it is praxis at Swedish universities that administration of subject headings is done by authors and not by professional indexers.
