Abstract (sommario):

The virtual fields method is a tool dedicated to the identification of the mechanical properties of materials from full-field deformation measurements. It is now validated in elasticity and plasticity but one of the remaining problems is the fact that researchers wanting to use the method must invest significant time in order to programme the routines. To help them, a software called CamFit has been developed. The purpose of this paper is to present this software. It is based on MATLAB® and uses a graphical pre-processing interface to produce the geometry, the conditions on the virtual fields, to choose the type of behaviour etc... Then, series of displacement maps are uploaded and the identification is launched. Since no iterative solution of the direct problem is required, computation times are very small compared to updating techniques. An important step in the procedure is the smoothing of the displacement measurements to produce strains. FE based approximations are presently available in the software. The final purpose is to introduce the software onto the market. This will be done in the very near future.

Abstract (sommario):

This thesis presents novel techniques for the generation and real-time rendering of globally illuminated environments with surfaces described by arbitrary materials. Real-time rendering of globally illuminated virtual environments has for a long time been an elusive goal. Many techniques have been developed which can compute still images with full global illumination and this is still an area of active flourishing research. Other techniques have only dealt with certain aspects of global illumination in order to speed up computation and thus rendering. These include radiosity, ray-tracing and hybrid methods. Radiosity due to its view independent nature can easily be rendered in real-time after pre-computing and storing the energy equilibrium. Ray-tracing however is view-dependent and requires substantial computational resources in order to run in real-time. Attempts at providing full global illumination at interactive rates include caching methods, fast rendering from photon maps, light fields, brute force ray-tracing and GPU accelerated methods. Currently, these methods either only apply to special cases, are incomplete exhibiting poor image quality and/or scale badly such that only modest scenes can be rendered in real-time with current hardware. The techniques developed in this thesis extend upon earlier research and provide a novel, comprehensive framework for storing global illumination in a data structure - the Virtual Light Field - that is suitable for real-time rendering. The techniques trade off rapid rendering for memory usage and precompute time. The main weaknesses of the VLF method are targeted in this thesis. It is the expensive pre-compute stage with best-case O(N^2) performance, where N is the number of faces, which make the light propagation unpractical for all but simple scenes. This is analysed and greatly superior alternatives are presented and evaluated in terms of efficiency and error. Several orders of magnitude improvement in computational efficiency is achieved over the original VLF method. A novel propagation algorithm running entirely on the Graphics Processing Unit (GPU) is presented. It is incremental in that it can resolve visibility along a set of parallel rays in O(N) time and can produce a virtual light field for a moderately complex scene (tens of thousands of faces), with complex illumination stored in millions of elements, in minutes and for simple scenes in seconds. It is approximate but gracefully converges to a correct solution; a linear increase in resolution results in a linear increase in computation time. Finally a GPU rendering technique is presented which can render from Virtual Light Fields at real-time frame rates in high resolution VR presentation devices such as the CAVETM.

Abstract (sommario):

La thèse est consacrée aux méthodes scientifiques de visualisation des champs électromagnétiques dans un environnement tridimensionnel. Les méthodes élaborées concernent trois domaines : la représentation graphique de données scientifiques, l'interaction avec l'utilisateur, la réalisation de la visualisation stéréoscopique. Des méthodes de navigation dans l'espace, de manipulation des objets et du contrôle de l'application stéréoscopique par menus ont été développés. Un scenarii d'interaction et de synchronisation des tâches est également décrit. L'extraction de valeur locales en un point quelconque de la représentation graphique constitue un point fort de la thèse. Cette opération est rendue possible par l'utilisation d'une structure de données originale. Un chapitre est entièrement consacré aux méthode de réalisation d'images stéréoscopiques et à leur recomposition pour obtenir une perception en relief. Les principaux paramètres sont déterminés par une procédure automatique
The thesis is devoted to the methods of electromagnetic fields' scientific visualization set in multidimensional virtual reality environment which gives spatial image and interaction with data space. Developed methods concern three domains: graphical methods of scientific data presentation, human-machine communication and realization of stereoscopy. In order to present volumetric and vector features the standard methods were adopted: colored maps (interactively cutting data set), isosurfaces and cones (vectors). The method of navigation within data space, objects' manipulation and control of application using menu system were developed. The most interesting method is numerical data querying directly from graphical objects realized based on the author's data structures. Much attention was devoted to stereo image creation and its influence on the space perception improvement. The result is the method of stereo parameters' automatic calculation

Abstract (sommario):

Ce travail se concentre sur le développement d'une procédure expérimentale d’essai mécanique à haute vitesse de déformation de matériaux. La nouveauté de ce travail est l'utilisation de champs d’accélération mesurés comme cellule de force, évitant la nécessité des mesures des forces externes. Pour identifier les paramètres constitutifs des matériaux testés à partir des mesures de champs, la méthode champs virtuels (MCV) basé sur le principe des puissances virtuelles (PPV) est utilisée. En dynamique, avec la MCV, il est possible de définir des champs virtuels qui mettent à zéro les puissances virtuelles des forces externes. Au lieu de cela, l'accélération obtenue grâce à une double dérivation temporelle des déplacements peut être utilisée comme une cellule de force. Enfin, les paramètres élastiques peuvent être identifiés directement à partir d’un système linéaire qui se construit en réécrivant le PPV avec autant de champs virtuels indépendants que d’inconnues à identifier. Cette procédure est d'abord validée numériquement par des simulations éléments finis puis mise en œuvre expérimentalement en utilisant deux configurations d’impact différentes. Les résultats confirment que effets inertiels peuvent être utilisés pour identifier les paramètres des matériaux sans la nécessité de mesurer la force d’impact, et sans exigence de déformations uniformes comme dans les procédures actuelles basées sur le montage de barres d’Hopkinson. Ces nouveaux développement ont le potentiel de mener à de nouveaux essais standards en dynamique rapide
This work focuses on the development of a novel experimental procedure for high strain rate testing of materials. The underpinning novelty of this work is the use of the full-field acceleration maps as a volume distributed load cell, avoiding the need for impact force measurement. To identify the constitutive parameters of materials from the full-field data, the Virtual Fields Method (VFM) based on the principle of virtual work is used here. In dynamics, using the VFM, it is possible to define particular virtual fields which can zero out the virtual work of the external forces. Instead, the acceleration obtained through second order temporal differentiation from displacement can be used as a load cell. Finally, the elastic parameters can be identified directly from a linear system which is built up through rewriting the principle of virtual work with as many independent virtual fields as unknowns. Thus, external force measurement is avoided, which is highly beneficial as it is difficult to measure in dynamics. This procedure is first numerically validated through finite element simulations and then experimentally implemented using different impact setups. Both results confirm that inertial effects can be used to identify the material parameters without the need for impact force measurements, also relieving the usual requirements for uniform/uniaxial stress in SHPB like test configurations. This exciting development has the potential to lead to new standard testing techniques at high strain rates

Abstract (sommario):

Experimental techniques for measuring the mechanical response of rubbers under dynamic loading are developed utilising the virtual fields method (VFM), to inversely identify constitutive behaviour from experimental observations. Rubbers and other 'soft' materials are difficult to characterize using traditional dynamic techniques such as the split Hopkinson bar: the low sound speed makes it difficult to achieve static equilibrium and the small supported forces give low signal-to-noise ratios in the experimental data. In this research, the dynamic VFM with the aid of high-speed imaging is applied to dynamic tensile experiments to resolve these difficulties. The VFM is a mathematical technique that makes use of the principle of virtual work. Manipulation of this equation enables us to remove the need for traditional force measurement, instead exploiting acceleration full-field data as a virtual load cell. Thus, the aforementioned difficulties are no longer of concern: the technique requires that the specimen is not in static equilibrium and that inertial forces are significant compared to material forces. Two dynamic tests and dynamic VFMs are developed and applied to tensile drop-weight and gas-gun driven experiments. The first uses small amplitude dynamic deformation superposed on static pre-stretching. Dynamic identifications at a number of pre-strains are collated to identify the complete nonlinear behaviour. The second utilizes a large strain amplitude of dynamic loading: one experiment characterizes the full response. Further applications of the dynamic VFM are explored in order to improve the first method and to extend the identification capability, and experiments performed at non-ambient temperatures allow a preliminary exploration of time-temperature superposition.

Abstract (sommario):

In this thesis I cover the theoretical framework and the practice based implications of bringing the fundamental principles of a cybernetic art educational strategy, the Groundcourse, which was developed and taught during the 1960’s in England by Roy Ascott, into the virtual, three dimensional builder’s world of the metaverse; to be implemented there as a non-institutional, voluntary, self-directed, adult oriented learning system for avatars – one which is expected to be taught by avatar instructors who will formulate the specifics of their curriculum and their methods based upon the cardinal tenets of the Groundcourse, which have been summarized by Roy Ascott as a flexible structure, “within which everything can find its place, and every individual his way,” which would give dimension and substance to the will to create and to change. In order to be able to set the groundwork for the adaptation of the Groundcourse’s principles to my model I have conducted literature reviews in experiential learning theories, with an emphasis on self-directed learning; as well as cybernetic learning. These I have combined with a survey of play theory and virtual world studies, particularly those focusing upon the avatar and metaverse creativity. From all of these I have woven together a foundation which I have combined with a visual documentation which may serve as case studies for my proposal. The new knowledge embodied through this thesis is a learning system for the creative fields that is designed specifically for the residents of online virtual worlds, and yet has its foundations in an earlier, well established and well regarded model.

Abstract (sommario):

Using theoretical and empirical methods, this paper proves that the modern mediaenvironment is a complex configuration made by the material and the virtual components and is reflected in the language in various ways. Innovative lexis with the component media and its systematization has become the key to understanding the mediareality, in particular, detecting the constituent elements of the structure of the mediatized environment. In total, 455 lexemes chosen from the Ukrainian dictionaries, academic publications, and the results provided by Google search engine have been analyzed. The systematization of the lexical units have been done according to the principle of the lexical and semantic field, and as the result macro-, midi-, and mini-fields have been allocated with the subsequent ranging of the lexis into the core, the centre, and the periphery. Within the macro-field MEDIAENVIRONMENT, the midi-fields have been located – TECHNICAL, TECHNOLOGICAL, and SOCIO-COMMUNICATIVE. The conceptual core of the macro-field MEDIAENVIRONMENT has been shown to form lexemes signifying space specified from the point of view of temporality, structuredness, contextuality, and evaluation. TECHNICAL midi-field is represented by the names of media equipment; TECHNOLOGICAL midi-field – by the names of methods, processes, and ways of using media equipment. The structural and semantic framework of the SOCIO-COMMUNICATIVE concentre is represented by mini-fields: WHO – FOR WHAT PURPOSE – WHAT – CHANNEL – TO WHOM – EFFECTS. The senders of information are shown as social institutions, groups, and individuals. The nominations of the addressee reflect the transformation of the passive information consumer to the user. The informational object has been specified according to its form, meaning, and the virtual «shell». The wide array of names for communication channels shows the link between the social field with the technical and technological ones, with their relative autonomy. The effects of consuming the information are verbalized by a smaller number of lexemes, largely of behavioral and evaluative nature. To sum up, the specified groups of neolexemes with the component media create a qualitative-quantitative hierarchical structure, the most numerous parts of which serve as the indicators of the most media-determined spheres of socioenvironment. Key words: mediaenvironment, structure, verbalization, neolexemes with the component media, lexical-semantical field.

Abstract (sommario):

Currently, museum pedagogy is a very promising area, covering all types of interactions between the museum and its audience. Museum pedagogy is an interdisciplinary field of scientific knowledge, “formed at the intersection of pedagogy, psychology, museology and the relevant discipline of the museum and built on its basis specific practical activities focused on the transfer of cultural (artistic) experience in a museum environment”. The rapid development of technology has led to the so-called modification of this scientific field, we mean a new branch of pedagogical knowledge is emerging - virtual museum pedagogy. VR technologies are beginning to occupy leading positions, but it is important to note that today in art pedagogy there is no idea how to build the educational process in such a context. Thus, this area of pedagogy today requires a deep and comprehensive study. This has determined the purpose of this study. The objectives of the study follow from the goal: 1) To reveal the specifics of virtual museum pedagogy 2) To develop basic pedagogical recommendations for conducting virtual excursions using VR technologies Materials and methods. The methods of this study were analysis and synthesis. Results and discussion. The results of the study consist in the VR technologies usage in art pedagogy features identification.
