This report is made as a literature review, focusing on the work done to increase understanding of efficiency in the categories of substations and secondary heating systems, with respect to the deviation from the theoretically possible cooling off in the distribution network as well as the economic benefit that appear. The main purpose of a considerable part of the literature used in this report addresses the issue of identifying individual causes of reduced cooling in district heating systems. These literature resources have been compiled and summarized as part of the report.The technology of district heating is associated with benefits such as better use of the energy in a fuel. This is the case of cogeneration plants where serial generation of electricity and thermal energy increases efficiency compared with the parallel generation where heat is generated locally and electricity is generated centrally. Serial generation thus allows for lower primary energy demand.

The Swedish preschool combines both education and care from a holistic point of view. This makes it even harder for both parents and the educators to make an objective evaluation on their own preschool. In Sweden we are proud to have one of the world?s best preschools. It is regulated by the government and is obligated to undertake critical evaluation from the state and the parents that are the consumers of these services.

Wireless communication is becoming more common, a relatively new technology within the area is Bluetooth Low Energy. It?s been developed to be energy efficient and in regard to compatibility. Alongside the growth of wireless technology, scientists and companies are looking for new areas of use. One of these is localization, which means to determine the position of a moving device with the use of stationary devices, an example of this would be GPS.This report means to evaluate indoor localization using Bluetooth Low Energy and was made for Combitech AB in Jönköping.

This paper analyzes Allt, Martina Lowden's novel from 2006, from a media discursive perspective. The theoretical framework consists of Michel Foucault's discourse analysis, Friedrich Kittler's research on hermeneutic reading, and N. Katherine Hayles's studies of pattern?randomness controlled meaning production. Various examples on how communication technology influences the narrator?s act of writing illustrate the medial discourse surrounding the body of Allt.

This report describes the development and implementation of a system for transmitting digital information at high speeds from a miniaturized submersible developed by the Ångström Space Technology Centre at Uppsala University. For instance, the vehicle shall transmit image data ? even stream live video - through an optical fibre to a monitor in a ground station. Hence, the system shall be used both to convert the image data to make it transmittable, and to recreate it at the receiver.The work includes a pre-study of the programming language and the technology used. A concept for the solution is presented together with main components later broken down into internal functions.

In this work we?ve been focusing on how to adjust educational computer games in order to make them suited for the educational context of upper secondary school. Our opinion and entrance to the study is that the related developers of the subject, in some ways, have failed to successfully combine and find the balance between the entertaining and pedagogical aspects in the games. Our main questions is which aspects in the games game developers need to take in consideration to satisfy the pupils, but also what qualities that is needed for them to function in their educational context. In order to do that we had to investigate the people of the target groups own perspective on what technological and social aspects in the computer games they assess as important.

The use of Web applications is a growing area. While the possibilities and functionalities are increasing, so is the complexity of them, together with the threats against them because the complexity also opens up the application to vulnerabilities. It is therefore important for developers to know how a web application can be developed with security in mind.This study?s intention has been to create an introductory documentation of what kind of techniques that exists which can produce higher security, which methods there can be within the development process and what to think about when programming secure web applications. In this paper we have investigated how theoretical manuals in the IT security department handles that area, and interviewed two developers from two different companies to see how they use security in their web applications.The study has an exploratory technical perspective and does not explain how to practically use and interconnecting different security-enhancing technologies, but is more suppose to give a first glance at what is available and sow a seed for those interested to continue reading further about the subject.

This thesis has its focuson media portrayal of a large political institution; the European Union. Articles from two nations daily newspapers have been analyzed in order to examine how the European Union is described and framed for their readers. The newspapers that was chosen for this study and from which the material was collected, were the Swedish newspaper Svenska Dagbladet the American newspaper The New York Times. The material was taken from three periods of time, and by this the results did not only serve a presentiment on how the media reports about the subject, but also an idea over the media?s coverage character over time.

The purpose of this study is to chart and describe which content and different models that teachers use when teaching English as a foreign language at upper secondary school in Sweden. The study was performed through a phenomenonographic point of view, where the aim is to present and compare different understandings within a certain area. Our study emanates in Lars-Göran Malmberg?s theories about different teaching models used when teaching Swedish, which have been transferred and modified by Bo Lundahl into teaching English as foreign language. On the basis of this theory, six individual interviews with different teachers at upper secondary school were carried out with concern of discussing the content and aim of English teaching.

Internet and information technology today has a rather obvious role in the activities of companies and organizations. All cash transactions within and between companies is digitized, communication within the company is done via e-mail, sales and marketing is done largely with marketing and ads on the Internet. This has resulted in economic benefits for companies and organizations, and facilitated the work for them. However, this has also led to new threats have emerged. Companies and organizations is well aware that there are numerous threats that comes with using the Internet and Information Technologies but exactly what those threats are for a mid-sized company in Sweden is not clarified anywhere.

Birgitta Stenberg?s autobiographical novel Kärlek i Europa was published in 1981. It takes placein the fifties and is written in a genre popular in Sweden during the seventies, the feministconfession novel. The genre had a strong political purpose, by way of sharing experiences ofliving as a woman in a patriarchal society the aim was to raise consciousness of oppression andmake way for liberation and sisterhood. But there was not room for everyone in the feministstruggle.

This bachelor thesis is about an ultrasonic sensor, implemented in a bubble chamber in Artis. The sensor consists of the piezoelectric sensor and an electronic control circuit. The control circuit consists of a programmable microprocessor, PIC18F2420 and a circuit, which sends the excitation signal to the piezoelectric sensor, and later receives the echo. This bachelor thesis consists also of a theoretical study, which examines different techniques of liquid level sensing in a chamber. The study discusses which factors are important in liquid level sensing and examine accepted methods.

I will in this paper give an introduction to the subject fields systemdevelopment, groupdynamic, conflicts and kommunication. The paper will fokus on what systemdevelopmentgroups can do before and during a project to support the teamwork and what systemdevelopmentgroups kan do to overbuild destruktive conflicts..

Detta arbete har två olika delar som behandlats på olika sätt. Inledningsvis har dagssituationen för teknikämnet i grundskolan kartlagts. Bland resultaten återfinns ett samband mellan behöriga tekniklärare samt de lärare som själva valt att undervisa i teknik, och intresset för ämnet teknik. De behöriga tekniklärarna återfinner vi framförallt i de större städerna. I den största gruppen lärare som undervisar i teknik, No lärarna, har endast tio procent valt att undervisa i ämnet själv.

This study is conducted with a focus on managers and its different forms as found in a nation wide Swedish bedroom specialist-organisation, Sängjätten. Leadership is perceived in many forms and depends on a large variety of factors within and outside the organisation. One of these factors is ownership and the characteristics these imply on the forms in which the manager works. Within the studied organisation there were two distinctive forms of ownership regarding to the stores we studied; such as franchising compared to the franchiser owned through a national headquarter, so-called ?self-proprietary stores?.
