In this project a simulator has been developed (in C++) with the purpose of illustrating how changes in environmental regulations, tax levels and other policy measures affect the composition of an energy system. The aim of the project was to investigate how energy companies? investment strategies are affected when changes in economic and environmental conditions occur. A standard scenario has been created based on current Swedish conditions, but the user can create new scenarios and set parameters freely. The user is tasked with building power plants to supply the city/region with district heating and electricity during a pre-set number of years. When the simulation is finished the result is graded in the following categories: economy, environment and quality. To evaluate the simulator three scenarios were created (?early 20th century?, ?reduced environmental control? and ?future?) in addition to the standard scenario and these were compared with each other by examining how a select group of power plants perform under the given conditions.

Background: The demand for sending letters, in the traditional aspect, has decreased because of electronic sources which have replaced a big part of letter communication. The Postal Service constantly strives for lowering costs and due to the changeable demand, a greater awareness is required regarding recourses and their usage. The previously mentioned measures in combination with commonly occurring quality issues during the collective process at the letter terminal in Alvesta would be improved by applying a lean-perspective to the process. A first step towards saving of time is to apply the ?value stream mapping?-method on the collective process for small and large letters.Purpose: To map the process of collection for small and large letters to be able to identify waste of recourses and furthermore give suggestions on how the Postal Service would be able to reduce the waste of recourses identified.

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.

This report will examine various solar energy technologies in order to decide if they could be applied in the Royal Seaport. The Royal Seaport is a Swedish urban district under development in Stockholm, with the goal of becoming a sustainable district. Two main techniques, solar collectors and solar cells, including sub-categories, are addressed in this report. Another sub-category, a hybrid system, will also be mentioned. The main difference between solar collectors and solar cells is the type of energy produced by the system.

In connection with the property crises in many countries, caused by the financial crises, people are now more aware of the risks involved in poor property-investments. The unusually cold winters along with extreme prices of electricity in Sweden in recent years has also contributed to increased interest in energy-efficient buildings.The process of developing a modern family home in Kiruna, Sweden is presented the first part of this paper. The house has been designed to withstand very high stresses from snow, low energy consumption as well as a high standard of living comfort. Aspects of the house covered here involves everything from construction, heating and ventilation to sanitation. Each of these areas is presented based on their underlying, scientific methods or theories.

The heating of companies premises is today functional with electrical heating and heating offossil fuel. The energy cost for these kinds of heating in buildings has heavily increased duringthe last years and the influence on the environment has become more visual. This leads to thatenterprises today become more anxious to render energy more effective and find alternativesolutions to their ancient heating systems. This is something that Skandinaviska kraftprodukterAB in Halmstad has become aware of.The purpose with this examination is to find the most cost-efficient and environmental measuresfor the office and workshop premises of SKP AB. Where one of the bigger things is to find agood alternative for their current oil furnace, which was heating the workshop.

This thesis has identified and studied measures to allow for reduced use of electricity in a waste incineration plant in western Sweden. The energy extracted from the waste at the powerplant is utilized and sold in form of electricity and heat. Technical and environmentally the combined heat and power plant is by today's standards among the leading waste incineration plants in the world. The owners are constantly striving to improve the efficiency of the waste incineration plant. They have seen the opportunities for savings in reducing internal usage of electricity.

In this report a study is carried out with the aim to identify added values of EPC projects implemented in schools in order to increase the interest of EPC projects on the market. The report examines how the planned maintenance, supervision, maintenance and corrective maintenance is affected, how insurance premiums and terms are affected, the indoor environment and how the tasks of the operating staff is changing. A literature study of energy savings, energy use in schools, maintenance and insurance as well as how energy efficiency improvements are related to the Swedish environmental objectives has been made. Visits were carried out in Ludvika, interviews were also carried out with operation technicians and local strategists in Ludvika as well as employees of insurance companies.Schools often have neglected maintenance and problems with ventilation and indoor environment. Schools also have a large energy saving potential due to their low utilization, mainly because they are empty parts of the year.

This master?s thesis was performed during the fall of 2006 at Cloetta Fazer AB in Ljungsbro. Cloetta Fazer is the market leader in Scandinavia of manufacturing confectionary and chocolates. The purpose of the project has been to identify causes that impact the quantity of waste in production as well as a cost/benefit analysis of the solutions that can reduce the problem of production waste.The work includes four production lines that are individually designed depending on what kind of product that are produced on the line. By using qualitative and quantitative methods such as focus groups, interviews and observations data has been collected.

Knowledge is today one of the most important resources for an organization to handle. But knowledge can also be difficult for organizations to manage. The internet is still growing and new tools take form that allows users to effectively share information. The purpose of this report was to describe how organizations can make use out of internal social media to facilitate knowledge management processes. Three issues involving mapping, coding and dissemination of knowledge to were produced to answer the thesis. The study was limited to examining the identification, coding and dissemination of knowledge through the internal social media plattformen, IBM Connections. The theoretical framework emphasizes how social networks can promote knowledge sharing, how a knowledge mapping can promote knowledge dissemination and sharing, how knowledge can be stored in data sources and how important interaction is to spread awareness. The theory has been supplemented by descriptions of how the system IBM Connections works. Surveys were conducted on four companies that use IBM Connections as an internal communication plattformen. The four companies were selected to illustrate how they use the plattformen of knowledge management processes and we chose to interview the people who were responsible for the introduction of the plattformen. The study identified several similarities between the different companies and that although there were some technical and cultural recalcitrant units against this new type of system within the organization so favored IBM Connections knowledge in several ways. The built-in search automatic created a map of knowledge through the plattform's user profiles. Saved files and documents could be found even after the employees left the company, which encodes knowledge into the company knowledge resources. The opportunity to interact with one another, often over great distances, favored the sharing of knowledge. A comparison with the theoretical framework provided us with the conclusion that internal social media can be used in several ways to Knowledge management through automated knowledge maps, the ability to store knowledge within the company and to communicate knowledge across functional and geographical boundaries in interactive discussions..

We have the tradition in Sweden to build villas and houses with a wooden framework. It has become natural for us because we have so much forest in our country. Building with wood has advantages, it is easy to process, but also disadvantages, as it is sensitive to moisture.Finland has long made use of the thermal blocks to build villas. It is a type of bricks that are a bit like a sandwich element, with a core of EPS and concrete on both sides of the core material. The concrete is hollow, so that after the walls has been bricked up you pour concrete into the hollow bricks.The issue of this report is to find out if concrete can be an alternative to wood as framework material in villas.

A district heating plant has the advantage that it can take advantage of the waste heat from industries and use of cheap fuels to produce heat. But for the long term is competitive requires that energy is also saved in district heating plants. One way to save energy in a district heating system is to increasing cooling to the return temperature. This leads to less power needed to drive the distribution pumps,  and that more energy could be extracted from the same amount of fuel by an improved flue gas condensation.In Karlskoga the return temperature into the district heating plant is high. They would therefore reduce the return temperature in order to extract more energy from the flue gases.

This essay describes my work as a director in a specialized orientation within psychodrama, surrealistic psychodrama. Using the language and performance techniques of theater and under the guidance of a director, psychodrama creates an improvised narrative or story. The essay describes several dramas I have directed, reflecting on my actions and choices as a director and group leader. I examine whether my working method has allowed me to be spontaneous and creative, which I believe the example of "The dangerous bear" demonstrates. The process enabled me to establish trust and receptivity so that a newly constituted group dared to investigate conflicts in symbolic ways associated with illness and death.

Music today is a big part of a person's everyday life and can influence emotions as wellas initiative and motivation. This effect together with development in technology hasled to that music today is accessible and can be played from a large amount of differentkinds of products. This in turn has meant that the demand for smaller audio playbackdevices is greater than ever.The goal of this project is to develop a concept for energy-efficient speakers withwireless communication that has the ability to obtain and play high quality music. Thespeakers will use the latest available technology and at the same time, using digitalsignal processing, have a low environmental impact through high energy efficiencyand low power consumption. Parallel to this work a pilot study will be conducted tosee trends in listener preference of sound.The result achieves the goals pledged while power consumption in sleep mode is solow that they meet the demands of tomorrow.
