Möglichkeiten der TexMind Software für die Generierung von textilen Strukturen für FEM Simulationen und CAD Anwendungen / Possibilities of the TexMind software for generation of textile structures for FEM simulations and CAD applicationsKyosev, Yordan 07 June 2017 (has links) (PDF)
Objekte der Simulation sind textile Strukturen - Geflechte, Maschenwaren und Gewebe. Diese können als Seile, tragende und deckende Strukturen in der Architektur, Bekleidung, im Medizinbereich usw. verwendet werden. TexMind Software beinhaltet mehrere Tools für die Generierung der Geometrie von textilen Strukturen und die Durchführung von einzelnen Berechnungen und Simulationen. Beispiele aus den Bereichen Flechten und Maschenware werden gezeigt. Neben den Vorteilen und der Möglichkeiten wird auch eine kritische Übersicht der offenen Punkte dargestellt. Möglichkeiten für Export zu FEM, CFD und CAD Software und solcher für Computer-Animationen werden demonstriert.

Reconstruction tridimensionnelle en vision par ordinateur : cas des cameras non etalonneesBoufama, Boubakeur 16 December 1994 (has links) (PDF)
Cette these concerne principalement la reconstruction tridimensionnelle a partir d'images issues de cameras non etalonnees. Deux autres sujets lies a la reconstruction ont ete traites : le calcul de la geometrie epipolaire et la mise en correspondance des points dans les images. Nous nous placons dans le cas general d'une sequence d'images obtenues avec une ou plusieurs cameras de carateristiques inconnues. Quand seuls les points observes dans les images sont utilisees la seule reconstruction possible est de type projective. Nous proposons d'abord une methode pour calculer la reconstruction projective, ensuite, montrons comment passer d'une telle reconstruction a une reconstruction euclidienne. Ce passage utilise des contraintes euclidiennes issues de connaissances a priori sur la scene tridimensionnelle. Enfin, nous proposons une methode de reconstruction euclidienne lorsque les parametres intrinseques des cameras sont approximativement connus. Cette methode utilise un parametrage permettant une grande stabilite dans les calculs Toutes les methodes proposees sont validees avec des exemples d'images reelles ou simulees.

Návrh metodické příručky ke geometrickému náčrtníku Geonext / Creating a methodical paper for using GeonextKUBŮ, Lucie January 2009 (has links)
The diploma thesis consists of four parts. The first part is theoretical and focuses on the use of PC in Math lessons, generally lessons in PC laboratory and the PC facilities of Czech schools. The second part of the thesis focuses on the Geonext programme which I have selected for its lucidity and simplicity in using the programme. Third part of the thesis describes a microexperiment, which I have conducted in 6th class of Grammar school. Exercises produced in the Geonext programme were used in this microexperiment. Exercises, which I have worked up in the Geonext programme, but did not use in the microexperiment, are described in the last part of the thesis.

LDPC kódy / LDPC codesHrouza, Ondřej January 2012 (has links)
The aim of this thesis are problematics about LDPC codes. There are described metods to create parity check matrix, where are important structured metods using finite geometry: Euclidean geometry and projectice geometry. Next area in this thesis is decoding LDPC codes. There are presented four metods: Hard-Decision algorithm, Bit-Flipping algorithm, The Sum-Product algorithm and Log Likelihood algorithm, where is mainly focused on iterative decoding methods. Practical output of this work is program LDPC codes created in environment Matlab. The program is divided to two parts -- Practise LDPC codes and Simulation LDPC codes. The result reached by program Simulation LDPC codes is used to create a comparison of creating and decoding methods LDPC codes. For comparison of decoding methods LDPC codes were used BER characteristics and time dependence each method on various parameters LDPC code (number of iteration or size of parity matrix).

A Study On Problem Posing-Solving in the Taxicab Geometry and Applying Simcity Computer GameAda, Tuba, Kurtulus, Aytaç 10 April 2012 (has links) (PDF)
Problem-posing is recognized as an important component in the nature of mathematical thinking
(Kilpatrick, 1987). More recently, there is an increased emphasis on giving students opportunities with
problem posing in mathematics classroom (English& Grove, 1998). These research has shown that
instructional activities as having students generate problems as a means of improving ability of
problem solving and their attitude toward mathematics (Winograd, 1991). In this study, teaching
Taxicab Geometry which is a non-Euclidean geometry is aimed to mathematics teacher candidates by
means of computer game-Simcity- using real life problems posing. This studies’ participants are forty
mathematics teacher candidates taking geometry course. Because of using Simcity computer game,
this game is based on Taxicab Geometry. Firstly, students had been given Taxicab geometry theory
for two weeks and then seperated six each of groups. Each of groups is wanted to posing problem and
solving from real life problems at Taxicab geometry. In addition to, students applied to problem
solving at Simcity computer game. Studens were model into Simcity game. They founded ideal city,
healty village, university campus, holiday village, etc. interesting of each others.

Modelling Geometric Concepts Via Pop-Up EngineeringMohan-Ram, Vivekanand 07 May 2012 (has links) (PDF)
The main purpose of this workshop is to focus upon a complementary approach to the study of, and the investigation into, concepts related to Geometry- Space Strand. It ought to benefit educators especially those who prepare teachers for the primary/elementary schools. Participants in this workshop will initially learn the skills needed in Pop-Up Engineering to produce ‘hole’ 3- D paper models which illustrate some particular geometric concepts. The process of the
construction of these models allows for building imagery, testing predictions, arousing and satisfying curiosity, connecting to Geometric concepts and most of all motivating and holding interest. It is envisaged that this approach to the teaching and learning of geometric concepts will provide grounds for discussion, enrichment, exploration, clarification of and ownership of ideas, and cross curriculum integration. It has the potential to reduce the apparent difficulty students experience with the study of geometric concepts.
