Ragdolls : En verletimplementation

Det huvudsakliga syftet med denna rapport är att genomföra och testa en implementationsteknik för ragdolls ämnade användas i spelsammanhang. Implementationen sker genom en kombination av en verletimplementering tillsammans med en fördefinierad bone-hierarki i meshen som skall användas. Verletimplementeringen programmerades som en grund till en enklare fysikmotor och parsningen och struktureringen av meshen sköttes parallellt utanför fysikmotorn. Rotationsmatriser för samtliga större kroppsdelar, såsom över- och underarmar, överkropp, huvud etc. beräknas sedan i fysikmotorn och används för att vrida mesh-kroppen rätt.

Högfrekventa tryckvariationer under de senaste århundradena

Long time-series of pressure measurements often have high quality because the early instrumentsare more or less the same as the modern ones. A time-series from Lund consisting of three dailymeasurements from 1780-1997 has been homogenised and is therefore suitable for analysingpossible influences of the enhanced greenhouse effect. According to a two-layer model of theatmosphere one finds a shift in the frequency of baroclinic instability due to an increasedtemperature gradient caused by the increasing CO2. Baroclinic instability over the Atlantic Oceanis the main cause for frontal zone production, causing cyclonic activity over the southern part ofScandinavia. Changes to the baroclinic instability would therefore be traceable in the time seriesfrom Lund.

Nationella prov i NO : Verktyg för likvärdig bedömning eller dolda svenskaprov som diskriminerar?

This study is focusing on students at compulsory level and their performance in national exam tests when the students first language is taken into account. Students in Swedish schools with non-Swedish speaking parents commonly follow language classes for limited Swedish proficient students. How does this affect their results when tested in other subjects as physics,biology and chemistry? A general claim is that national tests can provide data for balancedand fair grades. This view is challenged in this paper, through Principal Component Analysisof test results that shows a difference between schools when the schools social position and share of limited Swedish proficient students are measured.

Från föhn till feu! : Esrange och den norrländska rymdverksamhetens tillkomsthistoria från sekelskiftet 1900 till 1966

This essay is about the origin, planning and establishment of the European Space Research Organisation's (ESRO) sounding rocket base Esrange outside Kiruna in Northern Sweden. Three main questions are examined. First I show there were not just scientific and technical but also political, economical as well as military reasons to build a European rocket base. Second, I scrutinize the reasons to choose Northern Sweden as the location for the rocket base. As it turns out, the main reasons were the favourable location of Northern Sweden within the aurora oval zone, the proximity of the Kiruna Geophysical Observatory, and the possibility to use a large, although not quite uninhabited, area where the launched rockets could crash.

Hur kan intresse utvecklas för fysik och kemi i grundskolans tidigare år : - En analys av tidigare forskning

I den senaste PISA undersökningen från 2012 testades elevernas kunskaper i matematik, läsning och naturvetenskap hos femtonåringar runt om i landet. Sverige var det land som försämrat sina resultat mest av alla deltagande länder inom samtliga områden. Detta tyder på att något måste göras. Vi har studerat hur man kan väcka intresse för ämnena fysik och kemi inom naturvetenskapen. Detta för att öka de naturvetenskapliga kunskaperna hos eleverna i skolan.

NTA i förskola : En studie i hur förskollärare upplever att arbeta med NTA

AbstractThis study deals with NTA in preschool and the purpose of the study is to find out how the NTA project works out in practice. In the empirical study I have used questionnaires as a research method (Trost2001). Questionnaires have been sent to preschool teachers in the whole of Sweden to get as good a selection as possible. The responses received have been processed and analyzed. The results are reported below.The majority of the teachers thought it worked well to work with the NTA.

Ambulanspersonals uppfattning om fysiska tester och fysisk träning inom ambulanssjukvården

There is no standardized test to control the appropriate physical ability in the Swedish ambulance service. The county in question does not perform annual physical tests. A project has been going to develop science-based physical tests, designed for the ambulance service. The research has resulted in the Aasa-test.Objective: The aims of this study were to examine the ambulance staff perception of the Aasa-test relevance, introduction of annual tests and the importance of their own physical training in relation to ambulance work.Method: A quasi-experimental study with a comparative design has been conducted. Aasa-tests were conducted in 41 randomly selected staff at an ambulance station in central Sweden.

Fisk- och fågelpredations påverkan på den bentiska makroevertebratfaunans sammansättning under tidig vår i Tåkern

Predation is one of many factors that form the structure of the macroinvertebrate community in lakes, wetlands and watercourses. Earlier studies lack an examination concerning how fish- and waterfowl predation affect macroinvertebrates during shorter periods in the spring. I performed an exclosure study in the shallow eutrophic Lake Tåkern which is located in the western part of Östergötland County, Sweden. The experiment was performed during a three week period (1-21 April 2012) when the water temperature was low and the density of migrating diving ducks was high. The experimental cages used included three out of four different treatments; general predation (open cages), bird exclusion (net with mesh size 90*45mm) and no predation (net with mesh size 1*1mm).

Doktorander i fysik söker information : en intervjuundersökning av forskarens första tid som informationssökare

The aim of this Master's thesis is to examine difficulties concerning information acquisition, use, and management experienced by graduate students in physics during their first years of research work. Semi-structured, qualitative interviews were carried out with nine doctoral students. The theoretical background for analysis of the material is based on the work of Patrick Wilson, with particular focus on the concept of cognitive authority, and on that of Lars Seldén, who has proposed the idea of an information seeking career running parallel to the academic career of the researcher. Results from the interviews indicate that most of the students, in the early stages of their information seeking careers, rely to a great extent on supervisors and more experienced colleagues when identifying material needed for the research project. In a situation where information of potential relevance is abundant and where experience and focus are not yet fully developed, senior researchers function as cognitive authorities and as guides to other cognitive authorities.

Paul Tillich och Verkligheten : Är Bibelberättelserna "bara" symboler

In this essay I have aimed to examine how the theology of Paul Tillich relate to modern views of reality, both the way it was expressed in his contemporary time and the way I see it today. Reality I have defined as an entirety of the physic- and metaphysic reality. A so called panentism where God is reality and the world is a part of this reality.With Tillichs Systematic Theology as my principal material, I have first made a brief presentation of his theology, of its construction and main concepts. Then I have chosen to further examine the way he describes being, reason and revelation to see how this particular concepts of Tillich agree with my definition of reality. In this I have consulted the books Tillich in Dialogue by Mackenzie-Brown and Natural Theology Versus Theology of Nature, a book edited after the forth international Tillich symposium 1992, which had "Tillichs thinking as impetus for a discourse among theology, philosophy and natural sciences" as a theme.I have tried to point out the possibilities opened up by the ontology and epistemology of Tillich for the dialogue between theology and natural sciences.

Bilder av fysik : En studie om fysik på gymnasiet

I detta arbete sa? vill jag studera hur praktisk fysikundervisning och bedo?mning i na?grasvenska gymnasieskolor o?verenssta?mmer med modern forskning om fysikpedagogik.Denna forskning spa?nner o?ver ett brett spektrum av metoder och teorier, varav jag harfokuserat pa? om la?rarnas undervisning kan beskrivas som-elevaktiv eller inte,-mer eller mindre baserad pa? bokstudier,-inriktad pa? konceptuell fo?rsta?else eller mer fo?rma?gan att ra?kna specifika uppgifter.Dessa aspekter diskuteras a?ven i relation till de inblandade la?rarnas utbildning.Fo?r att kunna ja?mfo?ra de olika klasserna och la?rarna har jag anva?nt ett test avkonceptuell fo?rsta?else (FCI, se sektion 3.2) samt enka?ter till la?rare och elever.

Lärande och Utomhuspedagogik i Fysik på högstadiet (Learning and Outdoor Education in Physics at high school)

Skolverket redogör i Läroplan för grundskolan, förskoleklassen och fritidshemmet 2011 för att undervisning i skolan ska innehålla olika arbetsformer och varierande arbetssätt för eleverna att nå samma mål. Ett sätt att variera klassrumsundervisning är genom utomhuspedagogik. Utomhuspedagogik är ett komplement till traditionell undervisning och handlar om att undervisning och lärande sker genom upplevelser i utemiljön. Utomhuspedagogik kräver ett växelspel mellan teori, upplevelse och reflektion. Syftet med denna studie var att utreda huruvida utomhuspedagogik i fysikundervisningen på högstadiet var ett väl motiverat sätt att variera undervisningen, med avseende på hur elever påverkas av utomhuspedagogik utifrån ett såväl lärar- som elevperspektiv. För studien utfördes semistrukturerade intervjuer med två lärare och sex elever från två olika skolor i Skåne.

Individuation : Ontogenes : Prolegomena till Gilbert Simondons genetiska ontologi

The following text constitutes an attempt to present the French philosopher Gilbert Simondon's genetic ontology through an account of his reconfiguration of the problem of individuation in his doctoral thesis from 1958, L'individuation à la lumière des notions de forme, information, potentiel, métastabilité. The intention is to show how Simondon through this reconfiguration of a classical philosophical problem ? in which concepts and schemas from contemporary physics and technology is utilised in a critique of the bi-polar hylomorphic schema as its traditional, substantialistic solution ? becomes able to articulate an anti-substantialistic and anti-reductionistic ontogenesis as first philosophy. A systematic philosophical conception that according to Simondon precedes every critical investigation of the subject as well as every scientific ontology ? not by establishing a pre-critical position, but by exceeding Kant's critical position: that is, through a displacement toward a conception of the transcendental conditions for the genesis of being and thought as real conditions, rather than conditions of mere possibility.

Undersökning av förskolan Temmelburken certifierad enligt Miljöbyggnad : Termiskt klimat, energianvändning och höjning av certifieringsnivån

WSP building physics in Stockholm has certified the preschool Temmelburken in Bromma with the system of certification Miljöbyggnad. The rating of the building became BRONZE. In this thesis the preschool has been investigated with respect to the three areas: thermal climate, use of energy and improving of the level of certification. The thermal climate at the preschool has been investigated by a questionnaire survey and by measurements in order to do comparisons between the results from the two investigations as well as with the results of the simulations that WSP has done at the certification of the preschool. The differences between the results from the simulations and the questionnaire survey for winter as well as from the measurement performed with a comfort meter the 19th of March are concidered to be reasonably small since they give rise to the same rating according to Miljöbyggnad.   Operational data for the use of energy for the preschool have been obtained in order to do comparisons with simulations performed by WSP and Svenska Besiktningar AB. The comparison shows that the simulated values for the specific use of energy are lower than what the real specific use of energy would be for the preschool, since just the operational data for the heat energy is higher than the simulated values. At the investigation of the possibility of improving the level of certification it was found that the rating of the preschool can be raised from BRONZE to SILVER by improving the ratings of the ?thermal climate summer? and the ?daylight?.
