Empirical research shows that a possible reason why Swedish students mathematical knowledge deteriorates can be a too big focus on imitative reasoning, i.e. recalling solutions or follow algorithms, and a lack of creative mathematical reasoning, i.e. when a student construct his/her own solution and motivates its plausibility with mathematically well-founded arguments. The purpose of this study is therefore to examine if, and in what way, lecturers can provide students an opportunity to learn creative reasoning by simulating creativity in their presentations of examples. Six lectures were observed and 22 task situations were analyzed with respect to three aspects; reflection, plausibility and mathematical foundation, which are to be present in the situation if the reasoning will be seen as simulated creative.

The aim of this report was to investigate the hypothesis that Norway spruce (Picea abies L. Karst), planted on poor ?Scots pine? stands will not have sustained growth during the whole rotation, due to water deficit in the closed stands. In order to investigate this hypothesis, data from 10 Norway spruce stands in southern-eastern Sweden were collected. In 10 plots in each stand, diameter and breast heights were measured on every tree.

Contents:The evolution of today?s computer influenced society has taken giant steps towards virtual reality, game addictions and the possibility of not having to meet the people we communicate with. What is a reality today?To give a more concrete image of our question we?ve chosen the online game World of Warcraft as an example and to describe our connection to an alternative reality. We have performed different investigations, interviewed both gamers and non gamers, all this to give us the opportunity to see if the term reality has started to change in a direction that will allow us to call this alternative world a reality, or if it?s just a world wide phenomena of for example gaming addiction.

The purpose of this study is to investigate whether the new Swedish curriculum, GY11 brought with it changes to how non-religious world-views are presented in five different books in religious education, RE. The method used to analyze the material was a qualitative content analysis as well as counting the pages that dealt with secular world-views. This was later analyzed using philosopher Charles Taylors description and theory on secularization. This was used to identify secular processes as well as to define wether the books definition and description of secular world-views using Taylors concept of ?exclusive humanism?.The research questions are:? What are the authors writing about when describing the secular world- views?? What differences and similarities are there between the different editions prior and after the implementation of the new curriculum, GY11?? Are the secular world-views presented in a way that is compatible with Taylors concept of ?exclusive humanism??The results that are being presented are, first of all that the change between the different editions are not big.

To measure losses in a transformer with today?s methods is either slow or insecure. There s a new method developed by Alstom that hasn't been actualize in to a test-system and that has been the assignment in this project. The idea is built on a switched system and a CLR- circuit in the resonant frequency. The test-system has a calculated power-loss that make the efficiency to be as high as 99,8% and in reality over 95%.

The county of Dalarna is at present carrying through a process of digitalization where traditional x-ray film is being replaced with digital detectors. Earlier used methods for dose optimization turned out not being sufficient. This report presents a method to harmonize dose levels between x- ray sites equipped with Fujifilm imaging plate systems. An exposure index, S, related to the dose level of the examination is computed to every x-ray image. S turned out to be inversely proportional to the detector dose used at the examination.

AbstractThe background to this essay is previous experience in working in a preschool abroad. The teachers I met there did not relate to the children in the same way that I?m used to in Sweden. In my view, different expectations on the children, made them not make use of the children?s full potential to develop.The starting-point for this essay is the?life world perspective?.

I denna studie så kommer jag att analysera MMORPG-spelet World of Warcraft genom att utföra en analys i hopp om att isolera spelmekanismer och element som kan anses vara välfungerande och väldesignade. Jag kommer dessutom att bryta ner World of Warcraft till dess kärnkomponenter med hjälp av Interaction Centric Framework modellen som ett komplement till denna studie. Resultaten visar att World of Warcraft använder sig av många slags egenskaper och designval som skiljer sig själv från andra spel, som att dra ner på story element och att destillera spelets kärna till en väldigt grundlig ?morot-och-piska? formel som låter spelaren kunna spela oavbrutet utan att känna något skäl att sluta spela. .

With knowledge of how the southern Swedish forests have been affected by storms the past years, this study intended to find out which factors affect the storm firmness of a stand the most. The study was based on data from stands in the, by the storm Gudrun, affected area. The results of the analyses that tested the stand factors that influence the amount of storm damage to the greatest extent showed that the storm sensitivity of Norway spruce stands were largely due to previous management actions. The factors that could be controlled by thinning and had relevance of storm damage standpoint, according to the results were; the dominant height, volume, basal area weighted mean diameter and stand age at last thinning. In this study, these results are not as clear for Scots pine.

The aim of this study is to find a method to incorporate the energydemand of a building in the investment cost estimate.The study is based on an actual apartment block. The significant energyaspects are identified, and changed to more energy efficient options.These are then simulated using the energy calculation program VIP+.The calculated energy need is used in the investment cost estimate, andthe simulated alternatives are compared in regards to their economicalprofitability.Depending on the focus, different alternatives are the most advantageous.Since this study aims to show which alternative is the mosteconomically profitable, the annual profit is the parameter of mostimportance. This means that individual measuring of heating and hotwater use is the recommended change of the original house. A changeof the windows to new ones with a U-value of 1,0 as well as 0,8W/m2K also results in a positive change of the annual profit comparedto the original house..

This report is an attempt to clarify how religious and non-religious views-of-life [livsåskådningar] are created through the collaboration and opposition of religious and scientific elements/ideas. This with the hope of reaching a fruitful result related to the solution of world-view related conflicts, such as the ones existing between science and religion, on an individual and societal level.This is accomplished with the help of two assertions: (1) Mankind has a need to explain its existence and surroundings. (2) Religion and science has their origins in the same seed and aim to serve the same purpose, or function. Together these two assertions lay the theoretical foundations of this report which implies that all humans have an innate need of sustaining a stable world-view.The result of this report is that a final solution to world-view related conflicts are beyond reach as our mental and physical nature limits us. However there are strategies for minimizing world-view related conflicts effect on society..

The aim of the study was to analyse relations between the school and the surrounding world and how these relations affects the schools? work for sustainable development. This was mainly an interview study but teachers? self-valuations have also been used. Totally six teachers at two primary schools has been interwied.

This report intends to analyze the difference between the original rules and a modification of the rules for the Scandinavian version of the world famous dice game yatzy (yahtzee). Several works are made previously existing strategies for yatzy and Yahtzee.The study was conducted using the optimal strategy calculated and implemented in the programming language Java. The execution of the application to create the file containing the optimal strategy was running on leased powerful servers from Amazon and took just over six hours each.A simulated player played 100,000 games based on the strategy, to obtain data which then was used to plot graphs and analyze the expected score and its standard deviation. The expected value (mean) and standard deviation of the score for the possibility of three or four throws were 233.00 ± 44.82 and 280.07 ± 41.25.In view of the results drawn the expected conclusion that the four possible throws provides increased probability of getting a high score, unlike the case where the player may only be able to throw the dice three times. The fact that the variance is lower in the case of four throw session is equivalent to that the likelihood to get close to the expected value increases..
