Full textNetwork science has emerged as a fundamental field of study to model many physicaland real world systems around us. The discovery of small world and scale free propertiesof these real world networks has revolutionized the way we study, analyze, model andprocess these networks. In this thesis, we are interested in the study of networks havingthese properties often termed as complex networks. In our opinion, research conducted inthis field can be grouped into four categories, Analysis, Structure, Processes-Organizationand Visualization. We address problems pertaining to each of these categories throughoutthis thesis. (...)

Full texts attempts to implement Brechtian methods of Verfremdungseffekt with the same artistic intent of social change in their plays, Mad Forest and Red, Black and Ignorant. In order to provoke critical and objective thinking, and action for positive change, both of the playwrights make use of Brechtian Verfremdungseffekt techniques of characterization, open-endedness, episodic structure, and audio-visual aids. These techniques let the playwrights present familiar situations, actions and attitudes as if they were unfamiliar so that they could be alienated and evaluated with a critical eye by the audience and the reader. In addition to studying the Brechtian elements in these two plays, this thesis argues that there is a point which drifts Bond&rsquo

the point is that Red, Black and Ignorant includes non-Brechtian character design aspects and lack of Brechtian audio-visual aids.

Full textThe identification and exploitation of some of the audio-visual languages fundamental elements, by studying its origins, will allow us to suggest that these same remains are still present in the so-called Western cultural mode of news production nowadays. Probably, since the silent motion pictures, some visual imagery have been created and, therefore, in the 1930s, when finally there were technical possibilities to film a motion-picture, synchronize it with a sound stripe and exhibit it to large audiences, these patterns have been consolidated as audio-visual structures, which still endure, in essence, in news programming production at the beginning of this century. The analysis of a movie from 1930s golden period, when the filmic narrative had already solidified the use of sounds and images as commodities of its own language the western Stagecoach(1939) , it will function as a basis for the research carried out, later on, with Fox News Live, which is broadcasted by Fox News Channel; this investigation will permit the verification of some audio-visual constructions in cinema, besides its resulting permanence as sound-imagery structures in television, consequently, unconscious structures of discourse.

Full textIn the context of Advanced Driver Assistance Systems (ADAS) and Autonomous Vehicles, scene understanding is a fundamental inference process in which several servoing and decision making functions depends on. Such a process is intended to retrieve reliable information about the vehicle's surroundings including static and dynamic objects (e.g. obstacles, pedestrians, vehicles), the scene structure (e.g. road, navigable space, lane markings) and ego-localization (e.g. odometry). All this information is essential to make crucial decisions in autonomous navigation and assistance maneuvers. To this end, single or multiple perception systems are designed to provide redundant and reliable observations of the scene. This thesis is devoted and focused on image-based multi-body motion segmentation of dynamic scenes using monocular vision systems. The conducted research starts by surveying methods of the state-of-the-art and contrasting their advantages and drawbacks in terms of performance indicators and computation time. After identifying a recent vision-based methodology, sparse optical flow required pre-processes are studied. As a concept-proof, an algorithm implementation shows, in practice, limits of the addressed approach leading to envision and formalize our contributions. Detecting and tracking objects in a classic processing chain may lead to low-performance and time-consuming solutions. Instead of segmenting moving objects and tracking them independently, a Track-before-Detect framework for a multi-body motion segmentation (namely TbD-SfM) was proposed. This method relies detection and tracking on a tightly coupled strategy intended to reduce the complexity of an existing Multi-body Structure from Motion approach. Efforts were also devoted for reducing the computational cost without introducing any kinematic model constraints and for preserving features density on observed motions. Further, an accelerated implementation variant of TbD (namely ETbD-SfM) was also proposed in order to limit the complexity increasing with respect to the number of observed motions. The proposed methods were extensively tested with different publicly available datasets such as Hopkins155 and KITTI. Hopkins dataset allows a comparison under feature-tracking ideal conditions since the dataset includes referenced optical flow. KITTI provides image sequences under real conditions in order to evaluate robustness of the method. Results on scenarios including the presence of multiple and simultaneous moving objects observed from a moving camera are analyzed and discussed. In conclusion, the obtained results show that TbD-SfM and ETbD-SfM methods can segment dynamic objects using a 6DoF motion model, achieving a low image segmentation error without increasing of computational cost and preserving the density of the feature points. Additionally, the 3D scene geometry and trajectories are provided by estimating scale on the monocular system and comparing these results to referenced object trajectories

"This little chicken went to Africa : a historical survey into the development of narrative structures within relief printmaking in community centres in South Africa and a formal analysis of the relevance of the medium in contemporary children's picture book illustration."

Full textWhen dealing with emergent literacy in South Africa, the didactic aspects of picture books are often privileged over their aesthetic quality and the idea of reading for pleasure. The themes of the books are not always locally relevant and for economic reasons, they often fail to reach the communities that need them the most. By looking at the history of relief printing within a community environment, I hope to highlight how communities themselves may be able to develop locally relevant children’s picture books, instituting a ‘grassroots’ approach rather than the paternalistic ‘top down’ approach of the past. I will also be looking at the narrative and stylistic elements of relief printing that are complimentary to the picture book genre and how these can be utilised for a pleasurable rather than didactic approach to the narratives.
Heulot, Nicolas. "Etude des projections de données comme support interactif de l’analyse visuelle de la structure de données de grande dimension." Thesis, Paris 11, 2014. http://www.theses.fr/2014PA112127.
Full textThe cost of data acquisition and processing has radically decreased in both material and time. But we also need to analyze and interpret the large amounts of complex data that are stored. Dimensionality is one aspect of their intrinsic complexity. Visualization is essential during the analysis process to help interpreting and understanding these data. Projection represents data as a 2D scatterplot, regardless the amount of dimensions. However, this visualization technique suffers from artifacts due to the dimensionality reduction. Its lack of reliability implies issues of interpretation and trust. Few studies have been devoted to the consideration of the impact of these artifacts, and especially to give feedbacks on how non-expert users can visually analyze projections. The main approach of this thesis relies on an taking these artifacts into account using interactive techniques, in order to allow data scientists or non-expert users to perform a trustworthy visual analysis of projections. The interactive visualization of the proximities applies a coloring of the original proximities relatives to a reference in the data-space. This interactive technique allows revealing projection artifacts in order to help grasping details of the underlying data-structure. In this thesis, we redesign this technique and we demonstrate its potential by presenting two controlled experiments studying the impact of artifacts on the visual analysis of projections. We also present a design-space based on the lens metaphor, in order to improve this technique and to locally visualize a projection free of artifacts issues

Full textIn structural biology, the theoretical study of molecular structures has four main activities organized in the following scenario: collection of experimental and theoretical data, visualization of 3D structures, molecular simulation, analysis and interpretation of results. This pipeline allows the expert to develop new hypotheses, to verify them experimentally and to produce new data as a starting point for a new scenario.The explosion in the amount of data to handle in this loop has two problems. Firstly, the resources and time dedicated to the tasks of transfer and conversion of data between each of these four activities increases significantly. Secondly, the complexity of molecular data generated by new experimental methodologies greatly increases the difficulty to properly collect, visualize and analyze the data.Immersive environments are often proposed to address the quantity and the increasing complexity of the modeled phenomena, especially during the viewing activity. Indeed, virtual reality offers a high quality stereoscopic perception, useful for a better understanding of inherently three-dimensional molecular data. It also displays a large amount of information thanks to the large display surfaces, but also to complete the immersive feeling with other sensorimotor channels (3D audio, haptic feedbacks,...).However, two major factors hindering the use of virtual reality in the field of structural biology. On one hand, although there are literature on navigation and environmental realistic virtual scenes, navigating abstract science is still very little studied. The understanding of complex 3D phenomena is however particularly conditioned by the subject’s ability to identify themselves in a complex 3D phenomenon. The first objective of this thesis work is then to propose 3D navigation paradigms adapted to the molecular structures of increasing complexity. On the other hand, the interactive context of immersive environments encourages direct interaction with the objects of interest. But the activities of: results collection, simulation and analysis, assume a working environment based on command-line inputs or through specific scripts associated to the tools. Usually, the use of virtual reality is therefore restricted to molecular structures exploration and visualization. The second thesis objective is then to bring all these activities, previously carried out in independent and interactive application contexts, within a homogeneous and unique interactive context. In addition to minimizing the time spent in data management between different work contexts, the aim is also to present, in a joint and simultaneous way, molecular structures and analyses, and allow their manipulation through direct interaction.Our contribution meets these objectives by building on an approach guided by both the content and the task. More precisely, navigation paradigms have been designed taking into account the molecular content, especially geometric properties, and tasks of the expert, to facilitate spatial referencing in molecular complexes and make the exploration of these structures more efficient. In addition, formalizing the nature of molecular data, their analysis and their visual representations, allows to interactively propose analyzes adapted to the nature of the data and create links between the molecular components and associated analyzes. These features go through the construction of a unified and powerful semantic representation making possible the integration of these activities in a unique interactive context

This thesis addresses this issue from the perspective of Interactive Data Exploration and Analytics. We take advantage of the similarity-based image collection browsing paradigm and aim at meeting simultaneously the three following constraints: (i) handling large image collections, up to millions of images, (ii) handling dynamic image collections, to deal with ever-growing image collections, and (iii) providing interactive means to explore image collections. To do so, we jointly study the indexing and the interactive visualisation of large and ever-growing image collections

Structural analysis is quite an important job for the structure in its administration and maintenance. It’s a preventive measure that should never be ignored. In the past, we utilized software analysis to estimate the safety status of a building. These analyses were based on numerical values. However, their results were always enormous and overly complicated, and then confused the non-professionals. Obstacles were produced by such unreliable information transfer. In order to present the relevant numerical values in a detailed and visualized manner, we establish a 3D virtual interaction based on the results of analysis. After a few easy steps of menu selection, we can be on the scene with definitions and navigation. In this study, we are going to discuss the visual models of campus buildings and their damage analysis. A virtual reality model will be established and put into use. This study tries to discuss the visual simulation of architecture’s damage analysis. The damage analysis is based on the results of Nonlinear Static Pushover Analysis, which are generated by SAP2000. A system called Virtools is developed to produce the virtual reality in order to simulate the positions being damaged and warnings. Intuitional graphical user interface associates the users with the 3D space by visual simulation. A variety of virtual reality models can be presented to share the experience of highly interactive 3D content. It’s real time and beyond any limit of space. Reading, sharing, and utilizing these data are quite easy. If we utilize the models of this study as preventive measures in administration and maintenance, it’s possible for us to monitor the status of damage during the disasters and determine its safety class. Based on the simulations, we can also construct a learning system for the structural damage analysis.

The primary goal of this research is to develop a visual post-processor for inelastic static and dynamic structural analysis of three dimension systems. This program is entitled Visualization of Inelastic Structural Analysis for 3D Systems or VISA3D. The VISA3D program assists users in visualizing the structural responses obtained from a general purpose structural analysis program entitled Platform of Inelastic Structural Analysis for 3D Systems (PISA3D). The VISA3D program has been designed and developed using the object-oriented and three dimension computer graphics techniques in the Microsoft/Windows environment. The VISA3D is implemented using Visual C++. And MFC library is used to construct Windows program. Furthermore, by taking advantage of the Multiple Document Interface (MDI) supported by Windows, VISA3D allows users to concurrently work on multiple application examples and windows. It also supports various user-interfaces, such as pull-down menus, pop-up menus, tool bar, accelerators and mouse, to facilitate various kinds of post-processing tasks. In addition to display the structural model, including the nodes, elements and boundary conditions, VISA3D is capable of statically or dynamically displaying the mode shapes, deformations, extents and locations of plastic hinges of the structure in various colors and icons. The nodal velocity, acceleration and system energy distribution time histories can also be displayed.

Full textDans le cadre du droit d'accès à la justice, le phénomène de l'autoreprésentation est en train de devenir un élément structurel de la pratique judiciaire des procédures judiciaires civiles de première instance. Dans le contexte de l'autoreprésentation, l'élaboration d'une requête initiale cohérente et la prédominance de la forme de communication verbale sont deux variables qui conditionnent l'interaction des plaideurs, en autoreprésentation, avec le système judiciaire. Cette recherche porte sur la construction de formes alternatives de la représentation verbale de la requête initiale dans des procédures judiciaires peu complexes, en supposant qu'il soit possible, par un récit visuel, de décrire un conflit de manière cohérente, sans préjudice de la précision et de la rigueur, des garanties fondamentales dans les procédures judiciaires. De cette façon, et en supposant que le plaideur en autoreprésentation ne possède pas les connaissances techniques nécessaires pour préparer une requête initiale cohérente, on propose un modèle de cohérence structurelle d'une requête visuelle – afin de faciliter l'élaboration d'une description cohérente de la requête initiale, sous forme visuelle, pour les procédures civils peu complexes – et une méthode d'analyse de la cohérence d'une requête visuelle. Afin d'évaluer le modèle de cohérence structurelle et la méthode d'analyse correspondante, une procédure détaillée et systématique a été développée en utilisant une approche expérimentale. L'ensemble des résultats empiriques obtenus montre, avec une assurance, qu'un plaideur en autoreprésentation, ne disposant pas de connaissance spécifique lors de l'élaboration d'une requête initiale, est en mesure de créer une requête initiale cohérente à travers un récit visuel basé sur le modèle de cohérence structurelle proposé.
In the scope of the right of access to justice, the phenomenon of self-representation is becoming an important element in civil judicial processes presented to courts of first instance. The preparation of a coherent statement of claim is a critical element in the support to self-representation in the judicial system. This research explores the construction of coherent statements of claim, for low complexity judicial processes, based on visual narrative theory. Assuming that self-represented litigants may not have the technical knowledge needed to prepare statements of claim, we develop a model for representing statements of claim using visual narrative and propose a method for analyzing the coherence of statements of claim. Both model and method are evaluated using the experimental approach. The empirical results suggest the model and method support the construction of coherent statements of claim. These results contribute to promote self-representation and visual narrative in judicial systems.

Not only is billboard a significant feature in a great deal of Asia’s urban landscapes, it is to be observed everywhere and hardly undetected.Influenced by the activities of commercial behaviors, billboards of urban landscape tend to have different appearances. Spread out in tight squeezes, they are no longer single elements on a single building facade, but sequential disperse, or a spatial distribution, like a layer of skin lying on top of the building facade that creates a new street façade. In previous studies of billboards, researchers tend to concentrate more on subjective depiction with more sentimental statements than scientific analyses. Furthermore, previous studies narrow down the research scope by discussing the billboards per se, which trapped the studies in trivial details rather than broaden the complete picture that billboards bring to the urban landscape.The thesis attempts to observe urban characteristics that are shadowed by billboards via analyzing their visual structures. Another target intention of the thesis is to establish an analytical approach which is universally applicable in discussing and documenting billboards objectively without leaning toward subjective depiction. 1. Establish an approach that document and investigate billboards with universally applicable quality. 2. Reveal the composing structures of billboards in urban areas and to discuss the urban characteristics. 3. Disclose the possibilities of combining previous methods of urban analysis and the target approach which the thesis aims to establish. Compare and discuss the similarities and differences between the two approaches.
Bair, Wyeth. "Analysis of temporal structure in spike trains of visual cortical area MT." Thesis, 1996. https://thesis.library.caltech.edu/7600/2/Bair%201996.pdf.
Full textThe temporal structure of neuronal spike trains in the visual cortex can provide detailed information about the stimulus and about the neuronal implementation of visual processing. Spike trains recorded from the macaque motion area MT in previous studies (Newsome et al., 1989a; Britten et al., 1992; Zohary et al., 1994) are analyzed here in the context of the dynamic random dot stimulus which was used to evoke them. If the stimulus is incoherent, the spike trains can be highly modulated and precisely locked in time to the stimulus. In contrast, the coherent motion stimulus creates little or no temporal modulation and allows us to study patterns in the spike train that may be intrinsic to the cortical circuitry in area MT. Long gaps in the spike train evoked by the preferred direction motion stimulus are found, and they appear to be symmetrical to bursts in the response to the anti-preferred direction of motion. A novel cross-correlation technique is used to establish that the gaps are correlated between pairs of neurons. Temporal modulation is also found in psychophysical experiments using a modified stimulus. A model is made that can account for the temporal modulation in terms of the computational theory of biological image motion processing. A frequency domain analysis of the stimulus reveals that it contains a repeated power spectrum that may account for psychophysical and electrophysiological observations.
Some neurons tend to fire bursts of action potentials while others avoid burst firing. Using numerical and analytical models of spike trains as Poisson processes with the addition of refractory periods and bursting, we are able to account for peaks in the power spectrum near 40 Hz without assuming the existence of an underlying oscillatory signal. A preliminary examination of the local field potential reveals that stimulus-locked oscillation appears briefly at the beginning of the trial.

Full textA revolução da informação está abranger todas as organizações da sociedade moderna, forçando os especialistas na área de Tecnologias de Informação (TI) a transformar os seus processos de aprendizagem para a criação de valor. As tecnologias produzem e armazenam uma grande quantidade de dados para posteriormente serem produzidas informações. Entender o conjunto heterogéneo de dados e passar a reconhecer dados com significado é o grande objetivo do conceito Big Data. A necessidade de compreender e extrair conhecimento a partir do grande conjunto de dados é um processo difícil mas essencial para as organizações que lidam com informação. Neste contexto é necessário aplicar um processo de análise, limpeza e transformação de dados, denominado de Data Analysis. Este processo conduz o utilizador à escolha da técnica mais adequada perante objetivo da sua análise. A técnica estudada nesta dissertação será a Visualização de Informação (VI). A VI nesta dissertação é estudada com o principal objetivo de se transmitir informação de uma forma clara e efetiva através da utilização de representações gráficas. A mapificação de dados em estruturas visuais (representações gráficas) possibilitam uma vista detalhada sobre o contexto de dados e das suas relações. Os métodos e técnicas de Visualização de Informação evoluíram nas últimas décadas, em consonância com o avanço tecnológico galopante, daqui surge a necessidade de reformular o Modelo do Processo de Visualização, para facilitar a criação de uma representação visual. O objetivo principal centra-se na otimização dos métodos de Visualização – produzir uma representação clara e eficiente tem como principal finalidade potencializar a apropriação de dados por meio de representações gráficas. Para este objetivo foi formulado uma Classificação: “Representação Visual: o que pretendo transmitir”, que contempla o estudo de gráficos e das análises que surgem quando se pretende descobrir ou comunicar padrões e tendências nos dados. A Classificação foi construída como artefacto, com o propósito específico de ajudar o utilizador a decidir qual o gráfico mais adequado para evidenciar um tipo de análise. Para o estudo desta dissertação optou-se por aplicar como abordagem metodológica o Design Science Research, para a classificação sistemática de conceitos e construção da classificação. O utilizador como agente crucial durante o Método de Processo de Visualização: deve ser capaz de perceber qual é a análise mais apropriada para os seus dados e qual o tipo de gráfico mais rentável para o seu trabalho.
The revolution of information reaches all organizations of modern society, forcing experts in the field of Information Technology (IT) to transform their learning processes to create more value. Technology produces and stores a large quantity of data to be able to produce information afterwards. To understand the heretogeneous data and recognize data that matters is the ultimate goal of the concept of Big Data. The need to understand and extract information from a large group of data is a hard but essential process for organizations that deal with information. In this context comes the need analyze, clean and transform data. This process is called Data Analysis. The process guides the user to use the most suitable technique depending on the purpose of his analysis. The technique studied in this thesis will be Information Visualization (IV). The IV in this thesis is studied with the main purpose of transmitting information in a clear and effective way through the use of graphic representations. The mapification of data into visual structures (graphic representations) provide a detailed view of the data context and their relations. The methods and techniques of IV have evolved in the last decades, in line with the rampant technological progress, hence there is the need to redesign the Model of Visualization Process, to further the making of a visual representation. The main goal focus on the optimization of Visualization methods - the main purpose of producing a clear and efficient representation is to enhance the appropriation of data via graphic representations. To attain this purpose was formulated a classification: "Visual Representation: what I intend to transmit", which comtemplates the study of graphics and the analysis that arises when one wants to find or communicate patterns and trends in data. The classification was built as an artefact, with the specific purpose of helping the user to decide which graphic is the most suitable for a certain type of analysis. For the study of this thesis it was chosen Design Science Research to apply as methodological approach, for the systematic classification of concepts and the construction of classification. The user, as a key agent during the Visualization Process Method: should be able to acknowledge which is the most appropriate analysis for his data and what type of graphic is the most profitable for his work.

Full text(en) The teaching methods of quantum physics modern concept studying under conditions of credit-module system in High Pedagogical Universities are worked out. The content and structure of the part of «Quantum Physics» are investigated from the point of scientific and visual principles realization on the basis of system approach and technology of structure-logical analysis of educational material. It’s construction is explained on the basis of content logical consequence round the fundamental and through concepts and addition by modern concepts consideration. Methods, modes, forms and devices of teaching activity with structure-logical and emotional-valuable consideration of educational and cognitive activity are defined. It is set out that the addition to the course of general physics by modern contents and pointing out the ways of science and visual principles realization in experimental reflection of physical notions promote better studying of educational material and personal development of future teacher of physics. Efficiency of theoretical and didactics principles of the worked out teaching methodology for quantum physics knowledge forming under conditions of creditmodule system is experimentally proved.
