This report consists of two parts, out of which the first deals with the planning and designing ofa small house in the Swedish city of Huddinge, using the weather conditions of the Swedish cityof Malmö. The house has to be in accordance with the Swedish building- and constructionregulations, as well as with the limitations in energy consumption given.The house itself has to consist of at least two bedrooms, and blueprints of the house, variousconstructional elements, ventilation, sanitation and electricity have to be drawn. Calculations ofthese aspects also have to be made, to ascertain that the different parts function as they should,and that the dimensions are sufficient.The second part is called ?Allergy free home?, and investigates how indoor climate affects us,and whether it has changed during the last few decades. It also makes an effort to see whetherthe increase of allergies and asthma is correlated with possible changes in indoor climate, andwhether technical solutions might help to handle or even decrease the issues arisen.

Ocean Thermal Energy Conversion (OTEC) is a technology that utilizes the temperaturedifference in oceans between the warm surface water and the cold water at 1000 m depthto produce electricity. The purpose of this report is to investigate if OTEC with its synergiescould become a commercially feasible energy solution for a small island. A literature reviewis conducted to explore the different OTEC technologies and to what extent the threesynergies; fresh water, air conditioning and aquaculture, could be used. In order to calculatethe profitability of these synergies there is also a study conducted on the conventionalmethods and cost of fresh water production, aquaculture and air conditioning. A model is setup using a scenario of a small tropical Island with population of 100 000 people.

The aim was to explore how the first page of a student newspaper has been changed over time since it was founded in the 1960´s.This thesis explores how the front page of the student newspaper Lösnummer has been changed since it was founded in 1966. It concerns the location and frequency of elements and it is based on theories of layout, the first page and visual communicationIn addition, the thesis develops a new kind of method for determining the location of elements on the type area. The method is based on the hexadecimal number system. It is formed as a grid which is placed on the first page to determine the location of the elements.It concludes that the frequency of elements had its peak during the 1970´s and has ever since decreased gradually. Image placement has gone from being scattered all over the front page to be centered and increase in size. .

Purpose: The purpose of the study is to find out what mathematical content primary school children encounter in their free options at school.Through observation, the study defines mathematical areas that primary school students encounter in their free options at school. We want the study to show the reader the mathematics that students continuously meet without associating it with regular mathematics as taught in school.A number of mathematical areas have been defined in the analysis of the observations. These areas have subsequently been discussed more thoroughly. Finally, the areas have been arranged in a grid system to clarify the results.In our study, we have discovered that mathematics exists in all the observed situations the students participated in.We believe that observation as a method can give teachers a tool for helping students associate practical actions during their free options with the more theoretical aspects of formal teaching of mathematics. We discuss this further in the study..

Samhället och skolan följer varandra, de utvecklas hela tiden åt olika håll med olika pedagogik i grunden och olika politiker som styr. Däremot, det som följer med hela tiden, oavsett förändringar, och trots alla olika betygssystem, är att eleverna ska bedömas av sina lärare.  Bedömning och betygsättning är en viktig del i lärarens arbete och vikten av att det görs rätt och rättvist är i hög grad viktigt då det också kan sätta elevernas framtid på spel. Eleverna ska senare, efter grundskola och gymnasium, kunna söka sig vidare på sina betyg till högskola eller universitet. Det är viktigt att eleverna har fått rätt betyg, varken för höga eller för låga.

At the Division of Electricity at Uppsala University there is an experimental rig forhydroelectric generators. The experimental rig?s vital part is a 12-pole synchronousmachine, whose electrical characterizing parameters (resistances, inductances andtime constants) are unknown. The aim of this thesis is to characterize the machine inits current state by perform a Standstill Frequency Response (SSFR) test. From theanalysis of the measurement data, which is a part of the test, a set of basic parametershave been received.

The purpose of this thesis was to examine how locally produced bioenergy may contribute to meet the climate target year 2050 in the municipality of Uppsala. The goal of reduced GHG-emissions from current 6,8 ton CO2-equivalents to 0,5 ton CO2-equivalents per capita and year, year 2050 is based on avoiding harmful penalties of an increased level of GHG in the atmosphere. By estimating available biomass in the county together with examining future technologies and emission factors for the substrates used, four possible future scenarios has been developed focusing either on electricity generation or production of biofuels. GHG-emissions of year 2050 have been calculated using the software LEAP. The conclusion is that bioenergy, depending on how it is integrated in the energy system, may reduce greenhouse gas emissions between 0.6 ton CO2-equivalents and 1.4 ton CO2-equivalents per capita or 12% to 25% compared to 5.5 ton CO2-equivalents in the reference scenario 2050. The greatest reduction is obtained if biofuels are produced in combination with energy efficient heat requirements in buildings..

In this thesis proposals for different designs of a borehole thermal energy storage (BTES) have been developed for the building DN-huset in Stockholm, Sweden. To build a BTES results in savings in energy costs by approximately 44 %, i.e. 2 million Swedish crowns annually. Furthermore, a BTES would reduce the annual environmental impact with roughly 75-157 tonnes of CO2 equivalents per year, depending on how the electricity consumption?s environmental impact is estimated.

Denna studie har syftat till att undersöka serieentreprenörers kognitiva kunskapsstrukturer för att identifiera centrala faktorer vid affärsmodellering. Intervjuer har, med hjälp av intervjutekniken repertory grid, genomförts med tio serieentreprenörer runt om i Norrbotten. I denna studie har serieentreprenörernas affärsmodeller delats upp efter tillväxtgrad för att möjliggöra jämförelser av företag med olika tillväxtgrader. Jämförelserna visar hur serieentreprenörers kognitiva kunskapsstrukturer tar sig uttryck vid affärsmodellering i företag med olika tillväxtgrad. Data från intervjuerna har utmynnat i en medelvärdesanalys, en klusteranalys och en principalkomponentanalys som presenterats och analyserats med inspiration från studiens teoretiska referensram.

The background for my thesis is the fact that with rising electricity and oil prices it becomes interesting to calculate on alternative heating systems. I have chosen to calculate upon my parents? farm, which today heats the dwelling house with wood. This is very time-consuming work, time which could be spent on other work. The main objective for this study is to compare three different heating systems to decide how they differ considering effort and cost. The result from the calculations was that grain-heating system demanded the least amount of work, but the total cost was a little higher compared to chips heating. Chips heating required half as much work as today?s wood heating and had a little lower total costs compared with the corn heating. Which system to choose largely depends on how the own work is valued.

The aim of this thesis is to investigate the procurement of maintenance at SvK. Byunderstanding the process that has led to the current procurement strategy; providesuggestions to how the procurement of maintenance can be improved to ensure thequality of future maintenance of the national grid.A god client can be associated with a number of qualities, ?acquisition competence?.Vinnova describes acquisition competence as the ability to plan, formulate,communicate and monitor. Different businesses and industries have different needsand opportunities and operate in different economic structures which requireadjustments in their acquisition competence. A number of areas have been identified,called areas of focus, where clients can adjust their competences to their markets.The areas of focus are competition, competence/quality, control and communication.By defining the need of acquisition competence for SvK and identifying problems, anumber of suggested strategies have been proposed.
