The Work has been performed to, and in cooperation with Vetlanda Energi och teknik AB.District heating for commercial purpose started in the USA in 1877. Today the network has grown into big and complex systems, which demand maintenance and service to keep up the security of the delivery. When a district heating network expand, it becomes difficult to perform reliable calculations. For this purposes there are a few suppliers who design and deliver systems for documentation and calculation of district heating networks.Vetlanda Energi och Teknik AB is in the position where they must get a system for documentation and calculation for district heating, and therefore they need a basis to get a system. The target is to write a requirement specification that will follow the basis.The Swedish market has been inventoried, and suitable systems have been selected.

The Swedish building stock accounts for nearly 40 percent of the total energyconsumption in the country. Properties built today are likely to last for 100 years orlonger. This places high demands on long-term and smart energy solutions that willkeep the future Swedish building stock energy consumption at low levels. This thesishas focused on examining how the energy performance of buildings is affected bydifferent choices of window types in different cardinal directions. The objective wasto obtain a basis for recommendations on how window properties can be optimizedfor different types of buildings and orientations.

sustainable development by reducing the energy use by EU:s directive of energy efficiency and the UN Convention. The second purpose is to present the technical solutions regarding ventilation and heating system that is being used in passive houses. This was done using 8 passive houses, 4 germany and 4 swedish passive houses. Even the international and Swedish system requirements for passive houses have been addressed in this project. The goal was also to explain how and why the mechanical system in passive houses has developed to the technology used today.

By using industrialized building, pre-installed modules can be delivered to the construction site where they are easily mounted. This method has many advantages compared to on-site manufacturing, for example, the precision during the production process should be much higher than building each wall and floor on site. Furthermore, the quick erection procedure when using prefabricated elements and the possibility to use weather protection has the advantage of not being dependent on weather conditions, and many other factors.Masonite Beams AB is a Swedish company (a member of the Norwegian company, Byggma ASA) with a relatively new technology using light weight beams as bearing elements in the walls and a certain stiff board lamella slap which is mounted on the top of the floor structure creating an integrated stiff beam / board floor structure. The elements are flat which make it much easier to transport the elements from the factory to the building site where the building parts are easily mounted with special mounting stud.One of the main drawbacks of lightweight structure is the sound transmission. The main topic is low frequency annoyance, however the complex structural elements and their mutual sensitive connections other acoustical problems might appear.

In this paper my aim is to understand the trance movement from within as a collective phenomenon. I went to Turkey with my boyfriend David on a trance gathering, a festival called A Total Solar Eclipse Festival. There I did participant observations and interviews.Can Collins theory about interaction ritual be useful to raise the understanding? And is it fruitful to apply the term collective identity?The collective identity is build up by the festival as interaction ritual. It generates solidarity, emotional energy and a sense of belonging.In this paper I discuss different categories and symbols that the collective identity contains of.

The fishing port of Bläsinge is located on the east coast of Öland, Sweden?s second largest island. Today the port has a limited supply of freshwater. The economic association of the fishing port wants to expand their business, so that they will also include tourist services. To do this the harbor will need a more independant source of freshwater, with a higher quality than the present well.

In electricity markets evolving towards liberalisation and internationalisation, green certificates are seen as an important tool to promote production of renewable energy. In a green certificate market producers sell certificates received per unit of electricity generated from renewable energy. Trade in renewability is thereby decoupled from the the physical electricity trade. Tradable green certificates in combination with renewables obligation are implemented or planned in several EU member states. Integration at EU leveland the creation of a common certificate market seem like a possible next step.

This report is a result of a bachelor thesis at the school of Architecture and the Built environment (corresponding to 15 HP) and is written during spring 2012 at the Royal Institute of Technology (KTH) in Stockholm. The Bachelor's essay is based on the design and dimensioning of a house which is located at a predetermined site in Malmo, Sweden.The idea is to construct a house that is appropriate to use for an average Swedish family of four family members. The house is designed in a modern way with respect to ease of access and disabled facilities. The installation that have been considered are heating, ventilation, sanitation and electricity. Construction calculations and material selection are also discussed.Furthermore, a study about photovoltaic cells has been done.

The Republic of Moldova, situated in eastern Europe and a former part of the Soviet Union, is now experiencing a phase of transition in both society and landscape. They have hardly any fossil depots and are currently dependent on Russian gas, with 97% of their energy needs imported. The new elected government wants to move towards the EU and this is generally seen as the way to grow and reduce poverty. Security in the energy sector is important and one tool is to increase the use of renewable energy sources. Through interviews, texts, and visits I have studied the implementation of renewable energies (RE) in Moldova through a society development perspective. The study has aimed to investigate the sociotechnical complexity of this subject and to discuss the potentials and way of dealing with the subject in the specific cultural context of Moldova.

Climate change is the modern society?s common issue. The developed countries areconsuming more than what is sustainable, and the climate change due to the use offossil fuels can be seen clearly. EU has specified goals, in order to stop furtherdamage, which demand that every member state have to reduce its energyconsumption by 20 % before 2020 and 50 % before 2050, relative to 1995.The Swedish government uses a number of instruments to encourage reduction in theusage of energy, but every individual has to contribute to reach the goals.With increasing energy price the cost of living is going up. A lot of people are lookingfor ways to save energy and not be affected as much by the increasing price.Investments for insulation, replacement of windows and replacing old heating systemfor a new efficient heat pump is getting more and more common.This thesis is about investigating the possibilities in becoming independent from buyingenergy for households.

This essay attempts to examine the discourse of the Sweden democrats in relation to thevalue system of the Swedish national school.To analyse the political texts I use discourse analysis and especially the method and approachconducted by Judith Lee Bacchi. Bacchi focuses on the construction of a problem in variouspolitical discourses. When performing this kind of analysis the main question is (accordingto Bacchi): ?What is the problem represented to be??I find that the Sweden democrats construct the ?migration politics? and the ?multiculturalpolitics? that is guiding the society as the cause of most problems in our society. To solvethe ?problems? they promote a nationalistic and a cultural racist discourse especiallypinpointing the ?Muslims? as being a problem.Since the Sweden democrats are striving to implement their discourse in the society andschool, and since their discourse already are reproduced by solar students in the classroom,I find it important to examine the essence of their particular discourse and contrast it withthe current value system of the Swedish schools.I don´t find the nationalistic and racist discourse of the Sweden democrats to correspond tothe value system of the Swedish school, mainly due to their strive to create alienation, andby labeling individuals in a reductive manner, instead of using apparent differences as asource for democratic discussions in the classroom.

Abstract The purpose of this project is to develop a modular processor card which is intended to work as a platform for Kitron Development Karlskoga. The modular processor card is meant to be used as a control system in development projects, mainly in medical and industrial products. The processor card will consist of a central unit with the basic functions for a control system. Furthermore there will be complete modules with machine commodity and programming, to pick exactly the necessary functions for a specific application. With consideration to the specification of the development and the main unit, I chose an adequate microprocessor (AT90CAN32) as core and interface circuits to stated border areas. The construction is first completed in the program MultiSim and then remade in the program OrCAD Capture. The programming language C was used in the software model.

Rising complexity in the development of real-time systems has made it crucial to have reusable components and a more flexible way of configuring these components into a coherent system. Aspect-oriented system development (AOSD) is a technique that allows one to put a system?s crosscutting concerns into"modules"that are called aspects. Applying AOSD in real-time and embedded system development one can expect reductions in the complexity of the system design and development. A problem with AOSD in its current form is that it does not support predictability in the time domain.
