Since the 1990?s the Swedish school system has undergone major and recurring structural reforms. Two of the most comprehensive changes has been the shift of primary schools as an integral part of the welfare state to the responsibility of the municipalities as well as the introduction of free school choice for the students. Through two months of participant observations and semi-structured interviews this thesis seeks to answer the question of how these reforms has come to effect the work of teachers in a medium sized public school in a small municipality in the outskirts of Stockholm. Earlier research has shown that public schools in socio-economically vulnerable areas are disadvantaged due to the reformation of the school system (Beach & Sernhede, 2011; Östh, Andersson, & Malmberg, 2013).

A new material model, for the FE-program ADINA, has been verified against twoexperiments. One unreinforced concrete beam and one reinforced concrete beam.The model, DF-concrete, has the possibility to estimate true concrete. However theresults indicate that in order to be sure that the estimations are true, there ought tobe data from the true concrete to verify against.Two FE-models have simulated the behavior of a ring-shaped part of the nuclearcontainment vessel. The results from the first, frictionless, model agree with similarsimulations and hand calculations for high pressures in the containment vessel. Thesimulations of the nuclear containment vessel show cracking in the concrete after10-11 bars of over pressurization.

The purpose behind this work was to investigate whether I could from a practical approach to create desire for mathematics among students in primary schools. I wanted also to find out how students feel about their current mathematics teaching. By introducing an equation game, and interviewing students to find out their perception of their mathematics teaching, I was able to answer my questions. What I came to was that through a practical and laboratory work, I could create an enjoyable educational opportunity in mathematics. Then during the interviews I also learned that students had not a pre-determined negative attitude towards mathematics.

The following essay aims to determine what textbooks and teaching media educators in the county of Västerbotten use when teaching the relation between religion and science. Based on educational science theory and through analyzes of factual texts, the teaching materials was examined to determine how much focus they put on the thematic of religion and science. The result shows how the different teaching materials affect this thematic differently. The main conclusion is therefore that students in Sweden could, depending on the teaching materials used in their education, be taught by different standards to reach the same requirements..

The project Design analysis and proposals of plastic screw caps in Australia was performed at Högskolan Dalarna incooperation with University of Western Sydney, Australia. The Swedish company Tetra Pak, in Lund, were assigner forthe project that was performed 2006-2007. The commission was to do a survey about the packages for non-carbonateddrinks in Australia. The bottles had to be plastic, able to open in one step and with focus on the caps.The project has result in design analysis and a new proposal of a plastic screw cap for the Australian market. Sixbottles were choosen and they were all testet on 20 consumers each with a Likert-scale test.

During the work at Gateway Security AB in Motala I began examining available antenna models to get a wider perspective, this have given knowledge of their structure, and an understanding of their function. All my necessary fact is based on my observations and notes of these measurings. New antenna models, and available models were examined where measurements at different heights and different distances on the antenna were performed with the help of an oscilloscope and a measure probe, peak ? to - peak was brought on the signal. The measurements are presented in a line diagram.

This thesis describes a system for dealing with free surface fluid simulations, and the components needed in order to construct such a system. It builds upon recent research, but in a computer graphics context the amount of available literature is limited and difficult to implement. Because of this, the text aims at providing a solid foundation of the mathematics needed, at explaining in greater detail the steps needed to solve the problem, and lastly at improving some aspects of the animation process as it has been described in earlier works. The aim of the system itself is to provide visually plausible renditions of animated fluids in three dimensions in a manner that allows it to be usable in a visual effects production context. The novel features described include a generalized interaction layer providing greater control to artists, a new way of dealing with moving objects that interact with the fluid and a method for adding source and drain capabilities..

Electronic article surveillance (EAS) is widely used in shops and libraries together with an RF-tag attached to the goods or books in order to prevent shoplifting. By implementing the addition of a moisture sensor to the RF-tag, other functions become possible, including the ability to use as an alarm with regards to frozen goods, which have been shipped but which have melted and have, subsequently, refrozen. In- relation to care for the elderly, one time-consuming step involves checking whether there is the necessity for a change of diaper and this can, instead, be based on an RF-tag with an EAS-system alarm. A preliminary investigation was made using the moisture sensors, which involved how the resistance changes when liquid and/or heat is applied. A simulation of the LCCR circuit (RF-tag with the sensor) was conducted in order to determine how the resonance frequency changes for different resistances levels.

The focus of this project has been on the drainage tank of the reheater on Ringhals 1. This tank has on two previous occasions received such a high water level that the system automatically emergency stopped. For this reason, events and various readings from these two occasions has been specifically studied and analyzed. In order to prove theories about what causes these problems a model of the system was created in the program Dymola. Using simulation results from the model, we have been able to demonstrate how the system's measured values should look likeunder normal conditions with respect to flows, pressures, temperatures, valve positions and water level in the drainage tank.

Wireless sensor networks have the potential for becoming a huge market. Ericsson predicts 50 billion devices interconnected to the Internet by the year 2020. Before that, the devices must be made to be able to withstand years of usage without having to change power source as that would be too costly. These devices are typically small, inexpensive and severally resource constrained. Communication is mainly wireless, and the wireless transceiver on the node is typically the most power hungry component.

The objective of this thesis was to get more knowledge before an alternation of generations. In theses I have chose to make two drawings, one for dairy cows and one for cattle rearing. The drawings are made for a future alternation of generations at my parental home in the province Dalarna. The results are made out of educational visits at different farms and literature investigations. Those dairy farms who I visited had different milking system at each farm and the cattle farm I visited had beef production. The farms are placed in the middle and south of Sweden. At 1998 the Swedish Board of Agriculture decided to change the stall breadth and stall length and the result of this is that many farmers had to rebuild their cattle- and dairy buildings or end farming..

Syftet med denna undersökning har varit att ta reda på vilket sätt förskollärare använder dans som ett pedagogiskt verktyg med barn i åldern 1-3år. Jag använde mig av en kvalitativ metod och undersökningen genomfördes med hjälp av intervjuer av fyra förskollärare som var slumpmässigt utvalda. Därefter drogs det paralleller mellan intervjuernas svar och den valda litteraturen.Resultatet visade att samtliga förskollärare ansåg att dans var mycket viktigt för barnens utveckling. De använde sig av dans på något sätt i sin verksamhet men det var inte alla som ansåg att de använde dansen som ett pedagogiskt verktyg..

This thesis is commissioned by the Swedish electricity trading company GodEl with the purpose of evaluate solar electricity in multi-family buildings in the Stockholm region. The prices of solar panels have dropped recently due to the advances in technology, but the installation rate in Sweden remains low. It is therefore interesting to study the  profitability of solar electricity today, and if it is profitable enough to install based on profitability alone and not simply due to environmental considerations. Therefore this thesis first studies the profitability of solar panels based on a simulation of electricity production and consumption for multi-family buildings this region. The study concludes that solar electricity can be profitable in the Stockholm region under certain conditions; all of which have to be favourable for profitable solar electricity.The thesis also studies the opinion of the company's costumers concerning solar electricity.
