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.

This thesis was performed at Scania?s purchasing department of non-automotive products inSödertälje, Sweden during spring 2007. The management of the purchasing department ofnon-automotive products believe that their internal customers might not have fullunderstanding of what the purchasing department does. This is a problem because the internalcustomers might not use the contracts negotiated by the purchasing department or they mightnot involve the purchasing department when making purchases.The purpose of this thesis is to examine if and how the internal customers? perception deviatesfrom the purchasing department?s perception regarding the task of the purchasing department.And also to create a communication package with the purpose of increasing the internalcustomers understanding of what the purchasing department does.

The division of Electricity at Uppsala University runs a project called Lysekil project, they have designed a buoy that uses the waves to create electric power from a generator attached to the bottom of the sea.Uppsala University is closely connected with the company Seabased and the university makes use of their facilities in Lysekil. When they designed the buoy issues occurred, the geometric design was flawed, brackets with a short shelf life and it is generally uneconomic.A study visit was done in Lysekil on Seabased facility. With this visit the project started, which is to improve the design of the buoy and the attachment of wires leading to the generator. In this project we have chosen to use a beam system with three beams that are attached to the buoy. Then a wire attached to a plate that sits between the beams will be leading to the generator. Two proposals for construction are created, what distinguishes them are the brackets between the beams and the buoy.From these constructions, the design that is considered most optimal for our project is chosen.All parts of the buoy have been modeled and the drawings are designed in ProEngineer software.The two constructions are compared with each other, but the whole focus is on the second and final structure. The report begins with an introduction describing Lysekil project, and a task description of our project.The project aims to produce an optimal buoy that will be easy to design, materials restrictive with good durability and an economical solution.Wave power true function has been studied, mechanical and finite element analysis of beams, buoy and plate design.This has been presented in this report, where in the various chapters can read more about the processes. Although the relevant facts and information on this project and buoy development is included.

Purpose: To explore how the changes in work life, here represented and depicted through the concepts of knowledge work and knowledge worker, have been incorporated in the official psychosocial work environment discourse in Sweden. Methodology: Critical discourse analysis, contrasting the official psychosocial work environment discourse to literature on knowledge work and knowledge worker, to explore how employees, employers and their relations are constructed within these two discourses; focusing identity, autonomy and power. Using the constructions to make visible how they are articulated, used and dealt with in a real life case from the Work Environment Authority. Theoretical perspectives: Our social world is socially constructed and language is the main tool for constructing it. Discourse analysis is thus not just a tool for deconstructing texts but also for enhanced understanding of our construction of the world and our ability to communicate about it.

Övertoner orsakade av varvtalsstyrda motordrifter ger problem i industrisystem. Syftet med studien är att identifiera problemen och ge rekommendationer för att undvika dem. Studien utfördes som examensjobb på KTH för konsultföretaget Ramböll. En litteraturstudie i ämnet kombinerades med elkvalitémätningar på drifter hos Sandvik Mining.Elkvalitéproblem orsakade av varvtalsstyrda motordrifter kommer till stor del av att frekvensstyrningen ger olinjärt strömuttag som, om nätet inte är tillräckligt starkt, påverkar spänningskvalitén. Problemen kan vara driftstopp, störd utrustning och ökat slitage på utrustning för att nämna några.Denna studie visar att vid ändringar i system innehållande övertoner kan framtida övertonshalter approximeras för vissa fall.

AbstractElectricity consumption is a globally increasing problem caused by the high share of electricity produced in coal power plants. These contribute to high carbon emissions when only about 1/3 of the heat generate electricity and the remaining 2/3 of the heat cools off. Combined heat and power plants (CHP) have high efficiency because they use the residual heat for domestic heating. The CHP plant often use fuels from renewable resources, giving them a lower carbon footprint, but are also depending on the heat demand. If electric powered products such as drying cabinets convert to heat powered products more environmentally friendly electricity will be produced by CHP plants, which can supplant electricity, produced from coal power plants and reduce carbon emissions.

This thesis work has been performed at the department of diagnosis and dependability at Volvo Car Company, Torslanda. The background of this project is based on interest in ascertaining how different factors possibly can affect a diagnosis method, which has been developed to find leaks in the fuel tank and evaporation system. According to the OBD II requirements leaks with an orifice diameter larger or equal to 0,5 mm, must be detected. The idea of the diagnosis method is to create an over pressure in the system with an air-pump. The current through the pump is measured and correlates to the power consumed by the pump.

In order to facilitate design and maintenance of such a large and complex site as a nuclear power plant, all system functions must be described in a stringent way. In the past, these descriptions consisted of text documents and logical diagrams, but today there are an increasing number of object-oriented programs available on the market which might be used for this purpose. This Master Thesis has made a closer study of one of these programs named Rational Rose. The principal of the program is to facilitate software design and development, not to create models of plants. However, using the program the same way as developing software, specifying actors then gradually extend the model with use cases, use cases diagrams etc, the same methods can be used when modelling plants.

The purpose of my study is to find out how preschool teachers reason concerning their work withgender equality from outside of the curriculum. I propose the following questions: If there is apositive view over the relevance of gender equality from outside of the curriculum? Does thepreschool teachers think themselves to work with gender equality from outside of the curriculum?Does the preschool teachers have any thoughts on whether working with gender equality will have apositive or negative effect on the children? In what way does the preschool teachers reason on theirown meetings with boys and girls? The method chose to use is a qualitative study that is based oninterviews. I have interviewed four preschool teachers in a small society called Katrineholm. Afterthe interviews I have analyzed the material and split it into themes that has been processed.

The purpose of the paper is through a touristic view to see how the zoos have developed to modern zoss and interview Djurens Rätt and Skansen to see their view on "animal welfare". Another part of the paper is to see what the public thinks of animal welfare and if it's crucial when they choose a destination. We used a survey to see if the public has been influenced by any media in the aspect of their view of zoos. By seeing the evolution of zoos to the modern zoo, we can see how society had the power to influence. .

Popular culture is a phenomenon of growing importance in the society today. Children and teenagers are increasingly using popular culture in their everyday life to reflect and answer questions about their identities and the meaning of life. Swedish primary and upper secondary schools are expected to prepare their students for adulthood and to provide them with tools to explain understand and problematize contemporary society. From this perspective it is relevant to question whether the schools achieve this and whether the instruction given there represents the contemporary society. For the purpose of knowing more about how popular culture is perceived and dealt with in the Swedish education system, this study examines how eight textbooks in Religious Education (RE) and the national curriculum for upper secondary school discuss and treat popular culture.  The study focuses on when and in what ways the textbooks mention popular culture and if the curriculum provides any supportive base for including popular culture in religious education.

Which expectations did leading debaters place on fiction as an instrument in achieving societal changes hoped for by introducing the Public library? How can the value of fiction be described in relation to the mission of the Public library, according to these moulders of public opinion? Place and timeframe for this thesis is Sweden around the years 1905-1912 (period of formation of the Public library here according to the Anglo-American model). Starting point is the assumption that the Public library as a political institution is characterized by an ideological function. It produces meaning and norms, it sets standards of value. Method used is based on close reading and comparison.

The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.

The recent globalization has to some extent reduced the importance of specific cultures and instead creates a focus on the variation these different cultures provide. Under these circumstances the leader must adapt his leadership to face these new circumstances. The organisations today have to face these new leadership challenges which the global expansion brings. This is a prerequisite for organizations if they want to succeed and be more competitive in a more demanding environment.There are still big differences between the business cultures. There are also differences in the companies? home arena, between groups in the society and all the way down on a family level.

Numerical simulations play a vital role in both static and dynamic stability assessment of electric power systems and the foreseeing of voltage collapse. Simulations performed by Svenska Kraftnät(SvK) are mainly done in the specialized voltage collapse predicting software tool, SPICA and the more all?purpose software tool, ARISTO.The grid operators at SvK use SPICA to predict the maximum transfer limit at specified sections (in this report the section in concerns is the southern part of Sweden i.e. interface1 4). SPICA is mainly used as an online application by using actual states from the grid, these states update every quarter of an hour.This thesis is a continuation of the master thesis SPICA ? ARISTO JÄMFÖRELSE by Jakob Katzman and Johan Fält.
