Codes de Gray généralisés à l'énumération des objets d'une structure combinatoire sous contrainte / Generalised Gray codes for the enumeration of the objects of a combinatorial structure under certain restrictions.

Castro Trejo, Aline 15 October 2012 (has links)
Le cube de Fibonacci est un sous-graphe isométrique de l'hyper- cube ayant un nombre de Fibonacci de sommets. Le cube de Fibonacci a été initialement introduit par W-J. Hsu comme un réseau d'interconnexion et, comme l'hypercube, il a des propriétés topologiques très attractives, mais avec une croissance plus modérée. Parmi ces propriétés, nous discutons de l'hamiltonicité dans le cube de Fibonacci et aussi dans le cube de Lucas qui est obtenu à partir du cube de Fibonacci en supprimant toutes les chaînes qui commencent et nissent avec 1. Nous trouvons également le nombre de som- mets des cubes de Fibonacci et Lucas ayant une certaine excentricité. En n, nous présentons une étude de deux cubes du point de vue de la domination et du 2-packing. / The Fibonacci cube is an isometric subgraph of the hypercube having a Fibonacci number of vertices. The Fibonacci cube was originally proposed by W-J. Hsu as an interconnection network and like the hypercube it has very attractive topological properties but with a more moderated growth. Among these properties, we discuss the hamiltonicity in the Fibonacci cube and also in the Lucas cube which is obtained by removing all the strings that begin and end with 1 from the Fibonacci cube. We give also the eccentricity sequences of the Fibonacci and the Lucas cubes. Finally, we present a study of both cubes from the domination and the 2-packing points of view.

Analýza a vizualizace statistických Linkded Data / Analysing and Visualizing Statistical Linked Data

Helmich, Jiří January 2013 (has links)
The thesis describes several means of processing statistical data in the ambience of Linked Data and is in particular focused on the utilization of Data Cube Vocabulary metaformat. Its content offers a description of tools related to analysis and visualization of RDF data not only from the statistical view. An indivisible part of this work is the depiction of the Payola tool on whose development is the author still working on. The outcome of this thesis is mainly proposal and consequential implementation of the system that enables a conversion of RDF data in compliance with the DCV vocabularies. The designed system was implemented and integrated to the Payola application. Several other extensions of the system were also implemented by the author. Within the scope of the implementation process there are mentioned also limitations arising from the integration with Payola. In the conclusion the writer describes a few experiments where some of the chosen datasets were applied to the implemented system. Powered by TCPDF (www.tcpdf.org)

Cubes Émergents pour l'analyse des renversements de tendances dans les bases de données multidimensionnelles

Nedjar, Sébastien 23 November 2009 (has links) (PDF)
Découvrir des renversements de tendances entre deux cubes de données offre aux utilisateurs une connaissance nouvelle et intéressante lors des fluctuations de l'univers réel modélisé : quelles sont les nouveautés ? Quelle tendance apparaît ou disparaît ? Nous introduisons le nouveau concept de Cube Émergent. Il capture les renversements de tendances en mettant en œuvre une contrainte d'émergence (conjonction de contrainte monotones et antimonotones). Les bordures, classiques en fouille de données, sont reprises pour le Cube Émergent. Dans un second temps, nous proposons un nouveau couple de bordures pour optimiser à la fois l'espace de stockage et le temps de calcul. Cette nouvelle représentation fournit une caractérisation simple de la taille du Cube Émergent aussi bien que des outils de classification et de navigation dans les cubes. La connexion entre les bordures classiques et celles proposées est formellement établie en utilisant le concept de cube transversal. Connaître la taille du Cube Émergent est d'un grand intérêt, en particulier pour ajuster au mieux la contrainte d'émergence sous-jacente. Cette problématique est traitée en étudiant une borne supérieure et en caractérisant la taille exacte du Cube Émergent. Deux stratégies sont proposées pour estimer rapidement cette taille : la première est basée sur une estimation analytique, sans accès à la base de données, la seconde s'appuie sur un comptage probabiliste utilisant les bordures proposées comme entrée de l'algorithme proche de l'optimal HYPERLOGLOG. Grâce à la particulière efficacité de cet algorithme, plusieurs itérations peuvent être réalisées pour calibrer au mieux la contrainte d'émergence. De plus, des nouvelles représentations réduites et sans perte d'information du Cube Émergent sont proposées en utilisant le concept de fermeture cubique.

A Study on Conformal Antenna Solutions for Cube Satellites

Jamali, Maryam 01 August 2012 (has links)
This master's thesis presents a study on a slot and microstrip patch as the two main types of antennas for the use on Cube Satellite (CubeSat). A study on the fundamentals of the slot antenna is researched and a circularly polarized (CPd) cavity-backed cross slot antenna and its two-element array for the CubeSat are designed and fabricated. Fabricated two-element phased array cross slot antenna has higher radiation gain and steered radiation pattern compared to the fabricated single cross slot antenna. A CPd square microstrip patch antenna for the application of the CubeSat is designed and compared with a commercial CPd microstrip patch antenna. It is concluded that our designed microstrip patch antenna has a better performance compared to the commercial one. The last part of the research focuses on the design of miniaturized slot antennas for the CubeSat working at an ultra high frequency (UHF) band. The different techniques and challenges that we face through the miniaturization are articulated throughout the research and expanded upon in this thesis. The antenna simulations were performed using Ansoft High Frequency System Simula- tor (HFSS) and the final designs for the CPd cavity-backed single and two-element cross slot antennas and CPd microstrip patch antenna were fabricated using a circuit board milling machine. These were then measured inside an anechoic chamber for the radiation pattern. Both antennas had high radiation gain and good CPd radiation quality.

The Generalized Rubik’s Cube: Combinatorial Insights Through Group Theory

Helmersson, Calle January 2024 (has links)
This thesis examines the algebraic structure of the Rubik’s Cube—focusing on both the classic 3×3×3 model and its generalization to an n×n×n model—through the application of group theory. It delineates the fundamental group-theoretic characterizations of the Rubik’s Cube and establishes necessary and sufficient conditions for its solvability. Utilizing these conditions, formulas are derived for the number of solvable configurations of the Rubik’s Cube across all sizes.
