Extension des méthodes de géométrie algorithmique aux structures fractales
2013
Defining shapes by iteration allows us to generate new structures with specific properties (roughness,lacunarity), which cannot be achieved with classic modelling.For developing an iterative modeller to design fractals described by a BCIFS, we developed a set oftools and algorithms that permits one to evaluate, to characterize and to analyse different geometricproperties (localisation, convex hull, volume, fractal dimension) of fractals. We identified properties ofstandard CAD operations (intersection, union, offset, . . . ) allowing us to approximate them for fractalsand also to optimize these approximation algorithms.In some cases, it is possible to construct a CIFS with generalised HUTCH…
SUPER-RESOLUTION IMAGES ON MOBILE SMARTPHONE AIMED AT 3D MODELING
2022
Abstract. In these last years have been calculated several general algorithms to process the images acquired by mobile devices. Nevertheless, they don't always work at their full effectiveness due the numerous constraints and external issues. The latest generation smartphones, pushed by higher user expectations, have increasingly performing camera functions, in particular way, about the always increasing resolution, with a large number of pixels to process or two cameras for stereo view. Considering that pixels in an image sensor synthetizes the number of incoming photons, taking a photograph with a digital camera means to applying a low-pass filter to a scene where the tiny textures, such …
Una política juvenil para promover el desarrollo local: un estudio de caso
2019
El artículo presenta un estudio de caso de una política juvenil realizada en la última década en una región del Sur de Italia. Su interés reside en la versatilidad, el enfoque multidimensional y en el hecho de haber actuado como un óptimo instrumento de desarrollo local. El estudio de caso se ha realizado a través del análisis documental de las evaluaciones ex -ante, durante y ex – post que se hicieron para valorar el impacto de la política. La reflexión que el caso propone se enfoca en cómo se puede promover eficazmente el desarrollo local a través de políticas más trasversales.
The Norwegian Motion-Laboratory
2018
This paper contains an overview of the equipment currently available in the Norwegian Motion Laboratory, a description of the IT networking infrastructure in the laboratory, a GitHub link to open source code developed, description of the PyQt-based graphical user interface, presentation of robot forward and inverse kinematics, presentation of equations of motion for the suspended load motion and a description of the full system kinematics. The paper ends with a list of research experiments and publications from the laboratory to date.
Expression Therapies Through Installation
2017
La instalación como vía de expresión híbrida en la que se contempla la utilización del espacio con un sentido de intervención creativa, - arquitectura, pintura, escultura, fotografía, vídeo, performance, danza, dramatización y música- entre otras disciplinas implicadas, proporciona al campo de la terapia un universo sensorial y proposicional que puede tomarse como base conceptual en el proceso terapéutico mediante las artes.Partiendo del análisis sobre aspectos conceptuales y artistas de referencia de la instalación y tomando en consideración aspectos pertenecientes a terapias de expresión artística, se plantean sesiones arteterapéuticas fundamentadas en el uso de la instalación. The hybrid…
Cluny: de la gestion de données à la réalité augmentée
2007
Cluny III was the greatest abbey of the Christendom until the construction of Saint-Peters of Roma in the 17th century. Unfortunately, the Order of Cluny was broke up with the French revolution, and the church became a stone pit carry. Until 2010, for the commemoration of the Cluny foundation, a great restoration yard has begun. It is composed of two parts: Hézelon which is the restoration and development program for the patrimony of Cluny; and Gunzo, which is a research assembly on new image technologies, for knowledge and valorisation of the site. To facilitate the comprehension of this patrimony, and to allow the public to access its past, augmented reality features had been developed.
Multiverse Ethnography: A Qualitative Method for Gaming and Technology Use Research
2021
This article introduces multiverse ethnography as a systematic team-based qualitative method for studying the mechanical, structural and experiential properties of video games and other technological artefacts. Instead of applying the ethnographic method to produce a single in-depth account, multiverse ethnography includes multiple researchers carrying out coordinated synergetic ethnographic work on the same research object, thus producing a multiverse of interpretations and perspectives. To test the method, 41 scholars carried out a multiverse ethnography on two video games, Cyberpunk 2077 and Among Us. Explorative thematic findings regarding both titles are reported and methodological imp…
Константин Великий и св. Елена на фресках Яна Кубена в Воздвиженском костеле в Бжеге
2020
The paper introduces the splendid representations of Emperor Constantine the Great and Saint Helena in Jan Kuben’s frescos in the church under invocation of the Triumph of the Cross in Brzeg. They testify strongly of the incessant presence of the creative reflection over the Christian ancient times in the area of Opole Silesia in the period of the Catholic reform in the 18th century. Kuben’s trompe-l’oeil constitutes a wonderful combination of deeply experienced Catholic spirituality with the genius of the artist – a visionary.
Geometry control of the junction between two fractal curves
2012
International audience; The general objective of our work is to create a geometric modeller based on iterative processes. With this objective in mind, we have to provide tools that work with fractal objects in the same manner as with objects of classical topology. In this article we focus on the constructing of an intermediate curve between two other curves defined by different iterative construction processes. A similar problem often arises with subdivision surfaces, when the goal is to connect two surfaces with different subdivision masks. We start by dealing with curves, willing to later generalise our approach to surfaces. We formalise the problem with the Boundary Controlled Iterated F…
Fast 3D Ray Tracing for Indoor Coverage Solutions
2016
Optimal wireless indoor network planning requires huge number of iterations and evaluations of indoor coverage for each antenna location until an optimal solution is reached. Consequently, accurate and scalable calculation of power strength for indoor scenarios becomes necessary. The contribution in this paper is to reduce the complexity of 3D ray tracing for deterministic indoor power prediction. In order to achieve that while preserving the accuracy, image theory with feasible reflection volume as preprocessing approach is introduced. This proposed algorithm stores the image, its feasible reflection volume and valid area of receiving points. Significant complexity reduction is achieved by…
