Storing kinetic energy in a flywheel allows for more efficient driving of electricvehicles. Research in this area is in progress at Uppsala University, where a flywheelwith magnetic bearings encased in a vacuum chamber is being constructed. To makethis possible methods for measuring the current through the electromagnets in thebearings and temperatures in the flywheel need to be developed. This has been thepurpose of this report. The current measurement resulted in a resistive method, andthe implementation of eight measurement circuits in the system.

Our work is based on a mathematics test which the students accomplished, interviews with student and teachers who are working on this program and the current literatures. The purposes of this work are to search the importance and the effect of the languages understanding in students learning of mathematic in the Individual high school curriculum. In total, sex students and three teachers took part in our study. Tow of the students is mother tongue language student and the remains are second language student. Our study should answer tow important questions:? Do the student in the Individual high school curriculum have the fundamental knowledge in mathematic?? How does the understanding of Swedish language effect in the understanding of the mathematic problems and in the students results in mathematic test?In order to answer those questions, the students have to complete a mathematic test that consists of four parts.

This is a diploma thesis executed as a part of the examination of the educationalprogram Building engineer ? Construction management at Halmstad University. The aim of the thesis is to compare and evaluate conventional open-cut pipe-laying withhorizontal directional drilling. The thesis includes a comparison of the economic,environmental and time-based aspects of both methods and discusses which factorsthat determine the optimal choice of method.The study is mainly based on previous studies regarding the subject and oninterviews with professionals from the industry.A fictional project with five realistic cases of pipe-laying scenarios was compiled,sent to different companies for calculation, evaluated and compared. Our conclusionregarding when it?s suitable to use which method is entirely dependent on thespecific project.

The company Microshop is interested in implementing new features in their product-website, and would like to examine the possibility and usefulness of introducing such functionality. When designing interaction for commercial websites, it is important to make the menus easy to use, and refrain from using deep hierarchies in order to avoid causing unnecessary burden for the users. There is an interest among users for adaptive functionality, but this requires great amounts of trust in the website from the user. Something which can be created by refraining from using implicit information, and provide detailed explanations throughout the website. A usability test was conducted in order to complement the data gathered from the theoretical study, the interviews and the expert evaluations.

Detta examensarbete har gjorts på uppdrag av Compare Testlab på Sätterstrand, Hammarö. Målet med arbetet var att de?nera en uppsättning frågor och punkter som ska vara med i ett lättviktstest med inriktning på säkerhet. Efter mycket studier av böcker och webbsidor kom vi fram till att det inte var så lätt som vi trodde att de?nera ett allmänt säkerhetstest för mjukvaror eller applikationer.

Background and problem: In the last few years the threat against the environment and especially the emissions of carbon dioxide has become increasingly debated. The government have set up a goal to lower the emissions of carbon dioxide with 40 percent until 2020 compared to the level in 1990. The emissions in the transportation sector have, in contrast to the total emissions, increased since 1990 and will continue to increase unless powerful control measures are implemented. The lorry centres have to use strategies to answer to these external threats which lead us to the two questions of this thesis: - What methods do the lorry centres use actively and which do they consider as the most important methods for fuel saving? - Are there any differences which methods small, medium and large centres considers as important? Purpose: The main purpose of this thesis is to examine which methods lorry centres use actively and which they consider as important for fuel saving.

There are several methods and models within the areas of software engineering on how to proceed during a software development process. For each of these methods and models there are benefits and drawbacks, depending on how you choose to look at them. A difference of principle between the different models is that they either advocate iterative development or not. In parts of software engineering one makes use of different methods depending on which is most fitting in a specific situation. There are several methods on how to recieve more qualitative data from the end-users during the requirement collection, but the reappearing pattern is still user centric participation, which means that the user participates more actively in part of or the entire development process.

AbstractThe present thesis examines reading acquisition. The aim of the study is to gain a deepened understanding of various methods used for reading acquisition, how teachers? are dealing with these methods and what aspects require special attention. The overall research question of the thesis is: How can one assess children?s future reading ability and identify a method that is appropriate to this ability? The overall aim leads to several more specifically addressed issues.In the theoretical part, different perspectives and theories about reading acquisition are presented along with different methods for how to work in order to facilitate reading.

Two different methods for measuring biogas production were used, gas meter and gasbags. The gas meters were electronic and counted each time a certain gasvolume passed through them. The gasbags collected the gas that hade passed through the gas meter until a manual measuring could be done. The two different methods gave the same result for a volume at three liters but for a volume around 0,2 liters they did not. Accuracy and precision for the gasbags was more exact than for the gas meters even if the method was difficult with a lot of different elements that could affect the result.

Today, pigs are moved on farm, between farms, between countries and to abattoirs. This movement of live pigs requires handling practices that are designed for the purpose. The objective of this study was to research the use of paddle in moving pigs, to investigate if there were different methods of paddle practice, explore the time efficiency of different kinds of paddle use and if there were any time variations in methods that varied in intensity of touch. This study was done on two Swedish abattoirs for a total of five weeks. A total of 22 transporters working at two different abattoirs where studied during unloading of pigs at the abattoirs.

The report presents a thesis carried out on behalf of the company SAAB Training and Simulation which is situated in Huskvarna. The authors of this report are going to graduate as mechanical engineers focusing on product development and design, and this thesis should reflect the knowledge obtained during the education. The assignment, given from the company was to develop a concept of a stand that will constitute as a part of a mobile system for target practice. The reader get to follow throughout the project and can hopefully learn from the smart solutions and approaches that have arisen during the process.Today SAAB doesn?t have a mobile application in their portfolio that utilizes the benefits of their sensor measuring system, also called the LOMAH-bar.

Value-at-Risk (VaR) is among financial institutions a commonly used tool for measuring market risk. Several methods to calculate VaR exists and different implementations often results in different VaR forecasts. An interesting implementation is historical simulation, and the purpose of this thesis is to examine whether historical simulation with dynamic volatility updating is useful as a model to calculate VaR and how this differs in regard to type of asset or instrument. To carry out the investigation six different models are implemented, which then are tested for statistical accuracy through Christoffersens test. We find that incorporation of volatility updating into the historical simulation method in many cases improves the model.

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.

Syftet med föreliggande uppsats var dels att psykometriskt utpröva en svensk översatt självskattningsskala för bland annat skam, Test of Self-Conscious Affect (TOSCA) och dels att undersöka i vilken grad patienter, som får korttidsbehandling av social fobi med hjälp av kognitiv beteendeterapi upplevelse av skam förändras. För den psykometriska utprövningen utgjordes jämförelsegruppen av 72 st psykologstuderande vid psykologiska institutionen, Stockholms universitet. Den kliniska gruppen utgjordes av 8 st behandlingsdeltagare. Resultaten visar att TOSCA har en god intern konsistens och en hög test-retest relia¬bilitet. Dock kunde ej testets samtidiga validitet påvisas i denna studie.

The main purpose of this study was to collect norm data for thegrammatical receptive language test Test for Reception of Grammar - Version 2(TROG-2), from 144 Swedish children, aged 8:0-9:11 years. Another aim was toinvestigate whether a change in the order of the blocks was needed in the Swedishversion of TROG-2 to keep an increasing level of difficulty. Other aims included toinvestigate the relationship between receptive grammar and word decoding, andbetween parents ratings of their children?s language comprehension and readingabilities and the children?s results on the TROG-2 and a word decoding test. Theresults showed that the order of the blocks needs to be changed and that there wasno significant relationship between language comprehension and word decoding.Parents were better at rating their children?s reading than language comprehension..
