Embedded Systems Lab at Umeå University is currently part of a research project with the purpose to examine the behavior of dairy cows inside a barn. Each cow needs to be tracked with a precision of 50 cm, and since GPS-technique has poor functionality at indoor environments, an indoor positioning system needs to be developed.Embedded Systems Lab has already developed an indoor positioning system using IR-light and radio, but since this system demands extensive infrastructure and is rather expensive, an alternate positioning system using ultrasonic pulses and radio is being examined.In this report the range, beam angle and current consumption of ultrasonic transmitters- and receivers are investigated. Three different driver stages for the transmitter is tested, and two amplifier solutions for the receiver. The report also describes how the length of the transmitted ultrasonic pulse affects the received signal, accessibility of a ?shadowed? signal, and the effect of different sound frequency..

The purpose of the paper is to explore of what importance network relations are to the small fashion company Clemens en August. Clemens en August is a new German fashion label, which has the goal to become established in the high-end segment. The company uses an innovative sales strategy, directly distributing its products to the end costumer. The theories used will serve as a tool to analyze Clemens en August 's strategy from a network perspective. As the Bachelors thesis nr: 12464 ?Clemens en August ? A Network Perspective?, authors; Malin Elmlid, Biancastella De Angelis and Carsten Juldorf, date of approval 2006-01-11, contains delicate data about the studied company we have decided to classify it as secret.

This scientific essay is based on four self-perceived situations that all takes place in an outdoor environment. The children are aged seven to nine years. At least one of the children in the groups has some type of concentration difficulties. I have combined my practical experience with literature and previous research regarding outdoor education and children with concentration difficulties. Based on this I have tried to interpret and reflect on the opportunities and problems with outdoor education for children with concentration difficulties, especially so called situational concentration difficulties.

According to the study [1] several firefighters are killed in action each year. This happens naturally in various ways. One of the major factors is that firefighters often do not know how the environment looks like, for example that a building in an industrial area contains hazardous gas cylinders. Without a solution, fire-fighters will continue to die in duty. It is therefore important to solve this problem so that we can minimize the risks and save lives.The goal of this project was a control system for pneumatic artificial muscles.

The aim of the present study is to describe and analyse how an inter-cultural perspective presents itself in the didactic considerations and in the practice of preschool teachers on a multiethnic preschool.The theoretical perspective upon which the study is founded is social constructivism, but in addition to this Ingegerd Municio?s idea of two existing discourses present within the institutions in the Swedish educational system, as well as René León?s concept of a diversified normality, has been used as theoretical tools and points of departure.The empirical investigation consists of a qualitative field study at a multi-ethnic preschool, where participating observation and group interviews have been used to collect data. In these teachers from the preschool have participated.The results and the analysis of the data show that an inter-cultural perspective surfaces in the didactic considerations and in the practice of the preschool teachers in their construction of a diversified normality. The diversified normality thus constructed is constituted through different social processes. I have here identified the following ones: the preschool teachers emphasize differences among the children in general, they allow that the children behave differently and they allow them to be different; they recognize ?cultural? differences, differences in origin, and frames of reference, and they recognize that the children at the preschool are bilingual..

AbstractThis report is about the creation of a test system for development of a control system for a off the shelf RC-helicopter, which can be bought for about two thousand SEK. The test system consists of both electronics for controlling the helicopter and mechanical constrainer. The constrainer is used for mounting the helicopter so that it won´t crash.A circuit board including processor and sensors was manufactured. This was used for doing test of the different control algorithms. In this way were we able to analyze the quality of the sensors chosen, and what other sensors that could contribute to the control of the system.Basic helicopter control have been studied and presented in the report.

The European Union's work on equal opportunities for women and men can be described historically in three eras; equal treatment, positive action and, most recently, the gender perspective. In accordance with the latter, gender mainstreaming is the latest method in dealing with these issues. Its aim is the implementation of the gender perspective in all policy processes and to challenge the male norm that permeates all decision making. EU:s work on equal opportunities, though, persists not only of gender mainstreaming but has a double approach also including special actions.This thesis bases its argumentation on discourse analysis of communications from the Commission regarding employment and social affairs. It argues that the two components of the double approach; gender mainstreaming and special actions, are incompatible and even becomes contra productive put together.

The purpose of this study was to examine social worker?s own experiences of dealing with gender perspectives in child welfare cases. With a constructionist perspective, this study is based on a qualitative approach with semi-structured interviews. Six social workers were asked to reflect on their work and their methodology, and how it relates to gender perspectives when assessing children and adolescents in child welfare services.The result shows that there is a lack of control and review that children are given a gender neutral treatment. It also shows that there was no explicit protocol for how to take a gender perspective into account when assessing children and adolescents needs of welfare services.

Access to correct and updated intelligence about our environment is in an increasingly degree considered important in the private as well as in the public sector. At Mälardalens University, competitive intelligence as an area of research is closely related to Information Design - a multidisciplinary consideration which goal is to improve the receiver´s understanding of intended messages. This study was conducted in order to find out how Information Design was representedin different kinds of literature regarding Competitive Intelligence. Also, it describes the main focus areas concerning Competitive Intelligence in the same literature. Through an explorative "pearl-growing" method combined with searches through referrals, 60 different sources provide a broad basis for analysis.

This project started when LIC Audio AB wanted help with development of a hearing aid for public rooms. The problem is that a lot of people suffer from some sort of hearing impairment. In places with a lot of people and background noise the problem becomes bigger and the sound seems to flow together. During the project we found the solution for the problem in the shape of a headphone. The headphone receives a signal from a preinstalled hearing loop.

Political realism is a general theory within political science focusing on the principle interest defined as power. The theory?s mutual standpoint is that states are inspired by power politics meaning that military and economic power or security stands in the centre while moral and ethics are placed in the periphery. This essay?s purpose is to analyze realism which helps to understand the development and change of the perspective.

This masters thesis takes the providers perspective on public library story times for children. The main questions are: What perspectives can the providers have? How does the perspective affect the content and how is the story time drawn up? Five story time providers were interviewed about the purpose of their story times, the methods they used and the content they chose. A model with four criteria was used to analyze the result of the interviews. The criteria were: adult criteria, consideration of the childrens view, pedagogical criteria and literary/story time criteria.

A question that is asked far to seldom is what it means to be a good leader. The answer is not all that simple. It is a comlex and multi-faceted question that varies between the values and what ethical perspective you choose to have. As the title indicates, this essay has one particular ethical-theoretical perspective in focus, virtue ethics. According to the virtue ethics perspective a good political leader is a virtuous leader.

AbstractSchool is taking on a great responsibility in mediating knowledge of mathematics as technology is assuming greater importance in our everyday life. The aim of this study is to examine how the teachers in year F and 1 view their teaching of mathematics from an individually adapted perspective. I have based my research on different factual study books within the education for younger children?s learning of mathematics, and have from an individually adapted perspective made a comparison between theory and practice. The empirical data has been obtained through interviews with six teachers, three pre-school teachers and three teachers, working with pupils in year F and 1.
