District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

The purpose of this thesis is to study whether there is a demand for sawn wood products of large dimensions and planed goods among Wallnäs AB:s customers. The thesis consist of two main parts, one survey among Wallnäs present customers and another one which purpose is to increase Wallnäs customer base. Finally there is a chapter that describes what properties the raw material has to have in order to produce the demanded products. The survey to the present customers was conducted through a questioner. A sample of those who stated an interest for either sawn wood products of large dimensions or planed goods, were later contacted for a telephone interview. To reach out to new customers, relevant companies has been identified through the Swedish Trade Councils data base and through the member list of the Timber Trade Federation.

When the Swedish Forestry Act was changed in 1994, brushing of young stands became non mandatory. Since then the annual need for brushing in the country has increased by about 100 000 hectares per year. In later years the price for biomass energy has increased to the same level as pulp wood. The high price on biomass energy and the large areas of stands in the need of brushing has created a new market with its own technical, economical and environmental conditions. There is a development of various techniques to manage the forestry stands with late brushing.

The purpose of this thesis is to give an understanding of how grocery stores relate to local foods. Through a case study representatives for two groceries in Norrbotten have been interviewed regarding why they supply local foods, how they try to influence customers to buy this, and how they decide upon the assortment of local foods. The result shows that groceries supply local foods in order to supply a wide range of products and to mediate social responsibility, in order to create customer loyalty. Concerning how the groceries try to influence customers to buy local foods the result cannot give any clear-cut view. Instead it shows that a grocery that actively works to influence customers to buy local foods markets them in specific ways, while the opposite applies to a grocery that does not actively work for this.

This thesis has been done in order to ease the process of drawing schematics ofelectrical wiring. The need arose after demand from the government due to a seriesof incidents that took place during the revision of the nuclear power plant in year2009.The task of the project has been to create a computer program that can generate agraphical representation of the electrical components relations. The basis for theprogram has been an example of how the client wants the graphical representation tolook. During the course of the project weekly meetings have occured in which theclient has reviewed the work.The result of the project is a program written in Visual Basic Applications that can berun in Microsoft Excel. The program is capable of generating graphics for a majority ofthe cases.

The demands of environmental effects in today?s companies have been increasing more andmore. To be able to withstand customers, cooperatives and government demands the ISO14001 certification should not be neglected.In January 2007 the general management of SAS decided to introduce an environmentalmanagement system for SAS Tech. The work which has been carried out is a part of thecertification process of ISO 14001 which will be completed by the end of year 2009.The aim is to create auditroutines for the company in order to be able audit ISO 14001standard internally which is a demand to get certified and to keep the certification in thefuture. A schedule has been done which audits different part of the standard at every auditduring one year.

The purpose of this thesis was to make an energy survey and quantify energy flows of individual unit operations associated with the biogas production in Uppsala Vatten och Avfall AB:s biogas plant, located at Kungsängens gård. Moreover, large consumers of energy would be identified and analyzed. The objective of this energy survey was to obtain a detailed understanding of the energy use in the biogas production. The energy survey was divided into two parts: electricity and heat. Each part was treated separately and with somewhat different approach. To estimate the electricity usage during the projcet the rated power of each selected unit operation was noted and multplied with the measured time of usage.

The aim of this study is to illuminate and discuss a case of political steering, specifically Managment-By-Objectives (MBO) in Swedish municipalities, from a democratic perspective. The essay examines a discrepancy between MBO in the Swedish municipalities and democratic theory.To fulfil the aim of the study one leading politician and one leading civil servant from five municipalities have been interviewed on this matter. This material is discussed in the light of a democratic theory constructed specifically for this essay. The democratic theory consists of three main democratic values in the democratic process: debate, transparence and the ability to demand political accountability.The main conclusion is that there is a contradiction in the use of MBO and the democratic values of debate, transparence and the ability to demand political accountability. MBO has resulted in a lack of debate and transparency and furthermore, it has made it increasingly more difficult to demand political accountability..

The purpose of this master?s thesis is to contribute to the development of business relationships between a supplier and its customers. The research area and research problem was further developed into three research questions. The research questions concerns the following subjects: the substance of business relationships and dimensions within relationships management that can be used in order to contribute to the development of a company?s business relationships.

The purpose of the project is to determine the impact of solar cells and electrical vehicles on the future electricity grid and distribution network. Future electricity grids will be affected differently than it does today. Therefore, it is important to determine the impacts so that the current electricity distribution system can be developed and redesign to achieve the future demand. In Sweden, government has changed rules and laws in order to make it easier for private sector to invest in renewable energy sources. Our project focused on the impact of the solar cells and electric vehicles on the low voltage electricity distribution.

Background: Increasing globalization has changed the business environment and also resulted in increased awareness of the consumers and demand for higher standards of social responsibility. The companies brand strategies has gain in importance in order to strengthen their brands. A part of a company's CSR, CRM, cause-related marketing, which is a relatively new marketing strategy and created when companies choose to partner with charities and market it. Garment/clothing industry has as many others come to be shaped by the effects of globalization, but has also endured heavy criticism over the years. This criticism is largely because of the outside world's reaction to the exploitation of developing countries.

This essay focuses on strategies for acquisitions in Swedish publiclibraries. The topic has been occuring in the public debate off andon since the70s. The dominant view has been that librarians haveallowed demand direct the purchases of media and thus haveignored quality literature.This debate has caused me to reflect on the librarians constantdilemma when purchasing media. Are they supposed to chooseliterature that are in demand, or should an evaluation made bylibrarians be the decisive?The previous research has shown that the library profession istraditionally characterized by a non-judgmental approach.

This report describes the development of a high-voltage connector at the request of Scandinova Systems AB in Uppsala. The development process is described from the making of a customer demand specification, to the making of drawings for the manufacturing of prototypes. Scandinova develops high-voltage modulators, hence the need for connectors that can handle very large power pulses. Their current connector has several weaknesses that may cause the connector to melt or catch fire. The development began with a number of studies that included the modulator structure and the current connector structure and functions.

Environmental destruction is a growing problem in our world. Almost every day there are new reports concerning that we have to do something about the greenhouse gasses. Simultaneously is the human constantly more eager to have a life with higher standards and therefore uses more energy. The environment is a question that is highly up-to-date and more people try to find solutions on how to save our planet. One way to decrease the energy demand is to build passive houses, where the houses don?t have any active heating.
