IVL Svenska Miljöinstitutet utvecklade år 2001 ? 2002 i projektet ?Klimat.nu ? Den stora miljöutmaningen?, ett webbaserat verktyg för att upplysa och vägleda individen i klimatfrågan. Verktygets syfte är att kvantifiera fossila koldioxidutsläpp som en konsekvens av individens energikonsumtion; hushållsel, drivmedel m.m. Syftet är även att individen ges råd om hur man minskar CO2-utsläpp genom att förändra sitt leverne. IVL Svenska Miljöinstitutet vill utöka beräkningsverktygets innehåll till att även omfatta konsumentvaror.

The aim of this study is to examine the word acquisition, focusing on the nouns and word exercises, in two Swedish textbooks for German in the upper secondary school. The chosen method for investigating the nouns was corpus analysis. The noun frequency and distribution in the textbooks were analysed and discussed in relation to research in second language acquisition. The Involvement Load Hypothesis by Batia Laufer and Jan Hulstijn was used to examine the exercises in the textbooks. The study showed that most nouns only occurred once in the textbooks, but the most frequent nouns were well spread in the textbooks.

The aim of this thesis is to investigate how Bahamas, a magazine belonging to the antideutsche current in German left-wing politics, acted during a two year period between the summer 2001 and 2003. When explaining the anti-deutsche phenomena and the editors? politics it is common to take the currents own history-writing as a fact, thus presenting the development of the current as a reaction to outside factors and impulses outside. In this thesis it is stressed that the editors are far from only passively reacting, rather the opposite is true. I claim that the editors have a fixed ideology that they strive to implant in to certain parts of the radical left.

Civil society is facing many challenges in modern society and there is a lot of debate about where it is heading - is volunteer work declining or just taking a new form Whichever hypothesis will prove correct in the future, organizations that are dependent on volunteers will need to adapt to the new circumstances. This study aims to examine what forces drive voluntary work at Rädda Barnen (Save the Children Sweden) and Hungerprojektet (The Hunger Project Sweden). Through interviews with employees and volunteers at the two organizations, this study finds that volunteers at Rädda Barnen are primarily driven by values and understanding, and that the volunteers at Hungerprojektet are primarily driven by career and to some extent by values, enhancement and social factors. Understanding these driving forces allow the organizations to adapt to the new circumstances by matching the volunteers interests with the organizations' needs..

In this paper I study how the repeal of the Swedish wealth tax (1 of January 2007) has affected people´s labour supply behaviour. This particular issue is relevant because it may help us understand some of the effects of the earnings tax changes that have taken place in Sweden. Accoring to standard economic theory a repealed wealth tax is similar to an income effect for the persons who previously paid the tax. That means that they theoretically will want to consume more leisure, that is decrease their labour supply. The method I am using to test this hypothesis is a difference-in-difference approach where the treatment group consists of persons who previously paid the tax and the control group of comparable persons who did not pay the tax.

The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.

Cache simulator is a tool to increase the understanding of a cache memory. Therefore cache memory simulation is included in the course Computer Engineering IS1200 at the Royal Institution of Technology. The purpose of this project is to develop a cache memory simulator for education. The existing MipsIt and Mips Simulator which is currently used in IS1200 has been the main source of inspiration. This resulted in the development of the cache memory simulator LMSim.

With today´s power uprates in BWR reactors the bundle lift force has become aproblem. The lift force is calculated using a best estimate approach and the resultfrom the calculation should pass the existing lift force margin. Lift force margin isdefined so that the lift force may not exceed 80 % of the fuel weight. The margin issupposed to cover all the uncertainties that exist in the lift force calculations.However, no uncertainty analysis has been conducted to quantify the uncertainties.In this report the uncertainties in the lift force model have been quantified. Each inputparameter to the lift force model which has been assumed to have an uncertainty isassigned a probability distribution.

These studies are done in behalf of Saab AB AVITRONICS in Järfälla in the form of a thesis atthe Royal Institute of Technology in Stockholm.The task was to examine the parameters that plays a role in the construction of modern radomesoperating in broadband applications.This was interesting for Saab to get an indication of which way they should go at the newdevelopment of radomes for the next generation of equipment for electronic warfare.After a thorough analysis of the influencing parameters, a optimization application was made toget a automated way to get a radome design by specifying data on the radome size, airloads,materials, etc.This is to minimise the time of the laborious work that radome development.inply.This was solved by letting ANSYS calculate the strength of the radome structure and MATLABcalculate electromagnetic data and cost models of different sizes and materials.All these parameters woven together with the optimization tool modeFrontier picks data from therespective program and perform an optimization algorithm and then iterate a step and sends thisdata to calculation programs for the new input data. In the end, we have received a convergedpoint with our optimal solution.For the presumptions and limitations for which applied for this thesis, the result was prettyintuitive. That is to say that the smaller radome - the less materal is needed and lowermanufacturing costs results in the cheapest solution possible. The reality is not so simple. Whereyou have to take more of the electrical details such as the effect on the transmitter as a majorfactor..

Marinediesel has, to meet there customers needs for a suitable sterndrive to powerboats, developed a prototype. The prototype is currently in the testing phase. The opportunity to test the sterndrive under load inside the workshop has not previously been possible. Until now the drive has been tested in a test bench without any load on the propeller axle. The prototype has also been tested under real conditions mounted on a boat.The idea with my thesis was to create a test bench that can run around the clock in order to be able to test things like wear and service intervals and other things that require that the test interval is long.

Through interviews with children of ages 4-5 years old and by observing children children at play at three preschools with different types of outdoor surroundings, I have investigated if the preschools outdoor surroundings have any influences on the children´ choice of play. The hypothesis was that natural surroundings can entice children´s interest in nature being in it and play. I have also investigated if the children know why it is important to be outdoors and if they know it has a positive influence on their health.The result of my investigation is that the children play about the same games at the three different preschool gardens, but at the preschool with more natural surroundings, the children have more contact with plants and animals, and could learn of the different phenomena of nature by the preschool teacher answering their questions. Most of the children in the interviews know it´s useful to be outdoors and be on the move and get fresh air, but many of them thought it was most important to play. By being outdoors the children get exercise, fresh air, play and at the same time they establish an understanding of the nature and a healthier life..

The purpose of our essay is to study the institutional-, demographic and accounting theoretical factors that influence an organisations actuarial commitment.The research was performed through a web based survey, with complimentary telephone interviews, directed to companies listed on Stockholm Stock Exchange A- and O-list on the 30 of November, 2003.Our data was analysed with a Median test, Kolomogorov-Smirnov test, T-test and a Mann-Whitney test. The purpose of the Mann-Whitney test was the low number of respondents that took part in the research. The Kolomogorov-Smirnov test was done to determine whether the population variances was equal or not. The data showed that organisations with a majority of female employees assume a lower salary increase, and a higher average age than other companies with a male majority. Only 2 of 11 hypothesis can be accepted as temporary truths but several other visible relations are indicated in our research, but can not be statistically proved.We think that the major problem with our is the time it was performed.

A new phenomenon on the Internet is the online audience response. Mentimeter is a web-based tool where you can create online polls. The users can then cast a vote and the result is shown in real time. We want to test the information visualization in Mentimeter and we base our hypothesis, that a better graph design is possible, on the work of Edward Tufte and Stephen Few. Edward Tufte is an emeritus at Yale University, where he held courses in statistical evidence and information design and has created theories about how visual information should be designed.
