Choo, Jae gul. "Integration of computational methods and visual analytics for large-scale high-dimensional data." Diss., Georgia Institute of Technology, 2013. http://hdl.handle.net/1853/49121.
Full textAbstract:
With the increasing amount of collected data, large-scale high-dimensional data analysis is becoming essential in many areas. These data can be analyzed either by using fully computational methods or by leveraging human capabilities via interactive visualization. However, each method has its drawbacks. While a fully computational method can deal with large amounts of data, it lacks depth in its understanding of the data, which is critical to the analysis. With the interactive visualization method, the user can give a deeper insight on the data but suffers when large amounts of data need to be analyzed.
Even with an apparent need for these two approaches to be integrated, little progress has been made. As ways to tackle this problem, computational methods have to be re-designed both theoretically and algorithmically, and the visual analytics system has to expose these computational methods to users so that they can choose the proper algorithms and settings. To achieve an appropriate integration between computational methods and visual analytics, the thesis focuses on essential computational methods for visualization, such as dimension reduction and clustering, and it presents fundamental development of computational methods as well as visual analytic systems involving newly developed methods.
The contributions of the thesis include (1) the two-stage dimension reduction framework that better handles significant information loss in visualization of high-dimensional data, (2) efficient parametric updating of computational methods for fast and smooth user interactions, and (3) an iteration-wise integration framework of computational methods in real-time visual analytics. The latter parts of the thesis focus on the development of visual analytics systems involving the presented computational methods, such as (1) Testbed: an interactive visual testbed system for various dimension reduction and clustering methods, (2) iVisClassifier: an interactive visual classification system using supervised dimension reduction, and (3) VisIRR: an interactive visual information retrieval and recommender system for large-scale document data.

Full textAbstract:
Communication is an essential component of animal social systems and a diverse suite of signals can be found in the natural environment. An area of animal communication that, for technical reasons, we know very little about is the field of movement-based or dynamic visual signals. In this thesis, I make use of recent advances in measurement and analysis techniques, including digital video and image motion processing tools, to improve our understanding of how movement-based signals are adjusted according to signalling context. I measured and characterised the flamboyant claw-waving displays of male fiddler crabs (Genus Uca) and made use of their transparent lifestyle to record the behavioural contexts in which these signals are produced.¶
The claw-waving displays of seven Australian species of fiddler crab are compared and contrasted to show that these signals are species-specific, but also vary within and between individuals. I show that the species Uca perplexa produces different types of signal in different behavioural contexts, a lateral wave for courtship, and a vertical wave during short-range agonistic and courtship interactions. The structure of the lateral courtship waves of Uca perplexa vary according to the distance of signal receivers, the first time this kind of relationship has been shown in a dynamic visual signal. Finally, I describe and analyse the signalling and orientation behaviour of U. elegans during courtship herding, an unusual mating system that uses the claw-waving display in a novel way.¶
The adjustments made by fiddler crabs to their displays during changes in behavioural contexts suggest that the fine-scale context-sensitivity of animal signals may be far more widespread in communication than hitherto recognised.

Full textAbstract:
This project seeks to understand the relationship between visual rhetoric and power structure between FEMA’s Earthquake publications and their audience. Research shows images leave a longer impression on readers than text, causing more studies to focus on visuals rather than just text in technical communication. Author uses Critical Discourse Analysis to analyze the images in relation to text, design, and intended audience to determine what information is being privileged. It is determined that homeowners are being privileged with information over non-homeowners, established through a collection of images and image types. The lack of information for non-homeowners could result in injury or death of potential disaster victims, making it crucial for technical document revision.

Full textAbstract:
This thesis is primarily concerned with Caryl Churchill and Edward Bond&rsquos 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
s Red, Black and Ignorant from Brechtian dramaturgy and Churchill&rsquo
s Mad Forest
the point is that Red, Black and Ignorant includes non-Brechtian character design aspects and lack of Brechtian audio-visual aids.

Monahan, Richard. "Drawing perception : an analysis of the tectonics of drawing process and their influence on the structure of visual perception." Thesis, University of Wales Trinity Saint David, 2016. http://repository.uwtsd.ac.uk/729/.
Full textAbstract:
Since childhood, drawing has been a constant method and medium of enquiry for me, a medium that is beyond the term ‘art’, that is an instinctive physical and perceptual response to phenomena. As such, it is a natural development for me to desire to understand this phenomenon, to question the act of drawing as a mode of communication that appears to be so suitable to my understanding. This has led to a period of research into the formal structures of drawing, to ask how abstract marks on a ground can be of use to our understanding. Developed to question the universal relevance of drawing, this study is a practice-led investigation into the formal tectonics of drawing practice. As such it charts a period of research that comprises a re-learning of the building blocks of drawing practice in an effort to better understand how drawing influences how we encounter the world or, how drawing structures visual perception. Part I begins by outlining the historical lineage of which this thesis is a continuance, positioning the research as a non-essentialist, moderate manifestation of the formalist position. Part I proceeds to employ drawing as an analytical tool, to compartmentalise a past drawing into seven distinct components, identified as united within the diversity of the drawing process. The seven components are not original in their connection to drawing, and therefore do not, by their mere presence, comprise an original contribution to knowledge. In fact it is the universal acceptance of the components as the formal scaffold on which most drawings are built, that enables a rigorous interrogation of their properties to be undertaken, further explored and developed so that an understanding of how these components structure the visual perception of the drawer can be reached. Adopting the seven components as seven separate lines of inquiry, Part II establishes the Components of Drawing. Each is subsequently analysed and extended through my practice, theory and pedagogy. Within this process drawing operates as the principal originator, developer and vector of the hypothesis, the core of the investigation being a heuristic analysis of the structure of drawing that mobilises the components of drawing from a subconscious by-product of process, to a conscious understanding of the purposiveness of each mark made. The study concludes with a reflection on the research period in response to the hypothesis outlining the original contribution to knowledge, before positing possible future areas for further research.

Full textAbstract:
Humans are very effective at evaluating information visually. Scientific visualization is concerned with the process of presenting complex data in visual form to exploit this capability. A large array of tools is currently available for visual presentation. This research attempts to evaluate the effectiveness of three different presentation models that could be used for scientific visualization. The presentation models studied were, two-dimensional perspective rendering, field sequential stereoscopic three dimensional rendering and immersive virtual reality rendering. A large section of a three dimensional sub surface seismic survey was modeled as four-dimensional data by including a value for seismic reflectivity at each point in the survey. An artificial structure was randomly inserted into this data model and subjects were asked to locate and identify the structures. A group of seventeen volunteers from the University of Houston student body served as subjects for the study. Detection time, discrimination time and discrimination accuracy were recorded. The results showed large inter subject variation in presentation model preference. In addition the data suggest a possible gender effect. Female subjects had better overall performance on the task as well as better task acquisition.

Full textAbstract:
The advances in technology for creation, storage and dissemination of data have dramatically increased the need for tools that effectively provide users with means of identifying and understanding relevant information. Despite the great computing opportunities distributed frameworks such as Hadoop provide, it has only increased the need for means of identifying and understanding relevant information. Formal Concept Analysis (FCA) may play an important role in this context, by employing more intelligent means in the analysis process. FCA provides an intuitive understanding of generalization and specialization relationships among objects and their attributes in a structure known as a concept lattice. The present thesis addresses the problem of mining and visualising concepts over a data stream. The proposed approach is comprised of several distributed components that carry the computation of concepts from a basic transaction, filter and transforms data, stores and provides analytic features to visually explore data. The novelty of our work consists of: (i) a distributed processing and analysis architecture for mining concepts in real-time; (ii) the combination of FCA with visual analytics visualisation and exploration techniques, including association rules analytics; (iii) new algorithms for condensing and filtering conceptual data and (iv) a system that implements all proposed techniques, called Cubix, and its use cases in Biology, Complex System Design and Space Applications.

Full textAbstract:
In modern society, cancer has become one of the most terrifying diseases because of its high and increasing death rate. The disease's deep impact demands extensive research to detect and eradicate it in all its forms. Breast cancer is one of the most common forms of cancer, and approximately one in nine women in the Western world will develop it over the course of their lives. Screening programmes have been shown to reduce the mortality rate, but they introduce an enormous amount of information that must be processed by radiologists on a daily basis. Computer Aided Diagnosis (CAD) systems aim to assist clinicians in their decision-making process, by acting as a second opinion and helping improve the detection and classification ratios by spotting very difficult and subtle cases. Although the field of cancer detection is rapidly developing and crosses over imaging modalities, X-ray mammography remains the principal tool to detect the first signs of breast cancer in population screening. The advantages and disadvantages of other imaging modalities for breast cancer detection are discussed along with the improvements and difficulties encountered in screening programmes. Remarkable achievements to date in breast CAD are equally presented. This thesis introduces original results for the detection of features from mammographic image analysis to improve the effectiveness of early cancer screening programmes. The detection of early signs of breast cancer is vital in managing such a fast developing disease with poor survival rates. Some of the earliest signs of cancer in the breast are the clusters of microcalcifications. The proposed method is based on image filtering comprising partial differential equations (PDE) for image enhancement. Subsequently, microcalcifications are segmented using characteristics of the human visual system, based on the superior qualities of the human eye to depict localised changes of intensity and appearance in an image. Parameters are set according to the image characteristics, which makes the method fully automated. The detection of breast masses in temporal mammographic pairs is also investigated as part of the development of a complete breast cancer detection tool. The design of this latter algorithm is based on the detection sequence used by radiologists in clinical routine. To support the classification of masses into benign or malignant, novel tumour features are introduced. Image normalisation is another key concept discussed in this thesis along with its benefits for cancer detection.

A identificação e a exploração de alguns dos elementos fundamentais da linguagem audiovisual, ainda em seus primórdios, permitem sugerir que esses mesmos traços estejam presentes no chamado modo cultural ocidental de produção telejornalística da atualidade. É provável que, a partir do cinema mudo, certos padrões imagéticos tenham sido criados e que, nos anos 30, quando finalmente houve a possibilidade técnica de se fazer um filme, sincronizá-lo com uma banda sonora e exibi-lo para grandes platéias, elas tenham se cristalizado como estruturas audiovisuais, as quais permanecem, em sua essência, na produção dos programas jornalísticos do início deste século. A análise de uma obra cinematográfica do período áureo dos anos 30, quando a narrativa fílmica já tinha consolidado o uso do som e da imagem como matérias-primas de sua linguagem o western No Tempo das Diligências (Stagecoach, 1939) , servirá como base para a pesquisa realizada posteriormente com o telejornal Fox News Live, do canal de televisão Fox News Channel; isto possibilitará a verificação das construções audiovisuais do cinema e sua conseqüente permanência como estruturas sonoro-imagéticas na televisão, portanto, estruturas discursivas inconscientes.The 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 textAbstract:
Dans le contexte applicatif des Systèmes d'Aide à la Conduite et des Véhicules Autonomes (anglais ADAS), l'analyse de scène est un processus fondamental d'inférence duquel dépendent multiples fonctions d'asservissement et de prise de décision. Le résultat issu de l'analyse de scène permet une description fiable de l'environnement aux alentours du véhicule composée des objets statiques et dynamiques ainsi que des éléments de structure de la scène (e.g. route, espace navigable, marquage routier) et de la localisation du véhicule observateur (e.g. odométrie). Ces informations supportent les décisions et l'engagement d'actions des systèmes automatiques dans la navigation autonome et les manœuvres d'assistance à la conduite. Pour ce faire, les systèmes de perception sont conçus afin de fournir des observations de la scène redondantes et fiables. Dans le cadre de cette thèse nous nous intéressons à la segmentation d'une scène dynamique en utilisant des images issues d'un système de vision monoculaire. Dans un premier temps, une étude bibliographique des approches de l'état de l'art est présentée en contrastant les avantages et les limites des méthodes suivant des indicateurs de performance et de temps de calcul. Cela a permis la sélection d'une méthodologie récente basée vision servant de référence pour la segmentation de mouvement. Parallèlement, une étude approfondie des pré-traitements nécessaires à l'estimation du flot optique a aussi été menée. Cette première étape est clore par une implantation algorithmique pour la l'identification et la formalisation des contributions adressant les limites de l'état de l'art. Dans la deuxième étape de ce travail, nous proposons un algorithme de segmentation de mouvement basée image. Les notions et les méthodes introduites font appel à la technique du Suivi-avant-Detection (anglais Track-before-Detect) en couplage serré aux méthodes de calcul de la structure et du mouvement (anglais Structure from Motion). La méthode dénommée TbD-SfM a pour objectif la réduction de la complexité dans l'analyse de la scène intégrant un modèle de mouvement générique à 6 dégrées de liberté. Et cela en préservant la densité de caractéristiques suivies sur les mouvements observés. Plus tard, nous proposons une variante accélérée de l'algorithme TbD-SfM dénommée ETbD-SfM qui limite efficacement la complexité de la segmentation par rapport au nombre de mouvements observés dans la scène. L'ensemble des contributions a été évalué en utilisant différentes bases de données publiques reconnues dans le domaine des Transports Intelligents. Nous avons étudié les algorithmes TbD-SfM et ETbD-SfM avec le dataset Hopkins dans de conditions idéales : sans erreurs de suivi de caractéristiques et faible vitesse. Le dataset KITTI permit de vérifier la robustesse de l'approche et d'évaluer leur performance dans des scénarios incluant multiples objets en mouvement. Pour conclure, les résultats expérimentaux démontrent que les méthodes TbD-SfM et ETbD-SfM effectuent la segmentation d'une scène dynamique en utilisant un modèle à 6 dégrés de liberté obtenant une faible erreur de ré-projection tout en préservant la densité de caractéristiques essentiel au suivi de mouvement. La géométrie de la scène 3D calculée en estimant le facteur d'échelle est comparée et analysée aux trajectoires 3D des objets référencés dans la scèneIn 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

Thesis (MPhil (Visual Arts. Illustration))--University of Stellenbosch, 2009.When 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.

Full textAbstract:
Acquérir et traiter des données est de moins en moins coûteux, à la fois en matériel et en temps, mais encore faut-il pouvoir les analyser et les interpréter malgré leur complexité. La dimensionnalité est un des aspects de cette complexité intrinsèque. Pour aider à interpréter et à appréhender ces données le recours à la visualisation est indispensable au cours du processus d’analyse. La projection représente les données sous forme d’un nuage de points 2D, indépendamment du nombre de dimensions. Cependant cette technique de visualisation souffre de distorsions dues à la réduction de dimension, ce qui pose des problèmes d’interprétation et de confiance. Peu d’études ont été consacrées à la considération de l’impact de ces artefacts, ainsi qu’à la façon dont des utilisateurs non-familiers de ces techniques peuvent analyser visuellement une projection. L’approche soutenue dans cette thèse repose sur la prise en compte interactive des artefacts, afin de permettre à des analystes de données ou des non-experts de réaliser de manière fiable les tâches d’analyse visuelle des projections. La visualisation interactive des proximités colore la projection en fonction des proximités d’origine par rapport à une donnée de référence dans l’espace des données. Cette technique permet interactivement de révéler les artefacts de projection pour aider à appréhender les détails de la structure sous-jacente aux données. Dans cette thèse, nous revisitons la conception de cette technique et présentons ses apports au travers de deux expérimentations contrôlées qui étudient l’impact des artefacts sur l’analyse visuelle des projections. Nous présentons également une étude de l’espace de conception d’une technique basée sur la métaphore de lentille et visant à s’affranchir localement des problématiques d’artefacts de projectionThe 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 textAbstract:
En biologie structurale, l’étude théorique de structures moléculaires comporte quatre activités principales organisées selon le processus séquentiel suivant : la collecte de données expérimentales/théoriques, la visualisation des structures 3d, la simulation moléculaire, l’analyse et l’interprétation des résultats. Cet enchaînement permet à l’expert d’élaborer de nouvelles hypothèses, de les vérifier de manière expérimentale et de produire de nouvelles données comme point de départ d’un nouveau processus.L’explosion de la quantité de données à manipuler au sein de cette boucle pose désormais deux problèmes. Premièrement, les ressources et le temps relatifs aux tâches de transfert et de conversion de données entre chacune de ces activités augmentent considérablement. Deuxièmement, la complexité des données moléculaires générées par les nouvelles méthodologies expérimentales accroît fortement la difficulté pour correctement percevoir, visualiser et analyser ces données.Les environnements immersifs sont souvent proposés pour aborder le problème de la quantité et de la complexité croissante des phénomènes modélisés, en particulier durant l’activité de visualisation. En effet, la Réalité Virtuelle offre entre autre une perception stéréoscopique de haute qualité utile à une meilleure compréhension de données moléculaires intrinsèquement tridimensionnelles. Elle permet également d’afficher une quantité d’information importante grâce aux grandes surfaces d’affichage, mais aussi de compléter la sensation d’immersion par d’autres canaux sensorimoteurs.Cependant, deux facteurs majeurs freinent l’usage de la Réalité Virtuelle dans le domaine de la biologie structurale. D’une part, même s’il existe une littérature fournie sur la navigation dans les scènes virtuelles réalistes et écologiques, celle-ci est très peu étudiée sur la navigation sur des données scientifiques abstraites. La compréhension de phénomènes 3d complexes est pourtant particulièrement conditionnée par la capacité du sujet à se repérer dans l’espace. Le premier objectif de ce travail de doctorat a donc été de proposer des paradigmes navigation 3d adaptés aux structures moléculaires complexes. D’autre part, le contexte interactif des environnements immersif favorise l’interaction directe avec les objets d’intérêt. Or les activités de collecte et d’analyse des résultats supposent un contexte de travail en "ligne de commande" ou basé sur des scripts spécifiques aux outils d’analyse. Il en résulte que l’usage de la Réalité Virtuelle se limite souvent à l’activité d’exploration et de visualisation des structures moléculaires. C’est pourquoi le second objectif de thèse est de rapprocher ces différentes activités, jusqu’alors réalisées dans des contextes interactifs et applicatifs indépendants, au sein d’un contexte interactif homogène et unique. Outre le fait de minimiser le temps passé dans la gestion des données entre les différents contextes de travail, il s’agit également de présenter de manière conjointe et simultanée les structures moléculaires et leurs analyses et de permettre leur manipulation par des interactions directes.Notre contribution répond à ces objectifs en s’appuyant sur une approche guidée à la fois par le contenu et la tâche. Des paradigmes de navigation ont été conçus en tenant compte du contenu moléculaire, en particulier des propriétés géométriques, et des tâches de l’expert, afin de faciliter le repérage spatial et de rendre plus performante l’activité d’exploration. Par ailleurs, formaliser la nature des données moléculaires, leurs analyses et leurs représentations visuelles, permettent notamment de proposer à la demande et interactivement des analyses adaptées à la nature des données et de créer des liens entre les composants moléculaires et les analyses associées. Ces fonctionnalités passent par la construction d’une représentation sémantique unifiée et performante rendant possible l’intégration de ces activités dans un contexte interactif uniqueIn 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

Full textAbstract:
In this work, our goal is to track visual targets using residual vector quantization (RVQ). We compare our results with principal components analysis (PCA) and tree structured vector quantization (TSVQ) based tracking.
This work is significant since PCA is commonly used in the Pattern Recognition, Machine Learning and Computer Vision communities. On the other hand, TSVQ is commonly used in the Signal Processing and data compression communities. RVQ with more than two stages has not received much attention due to the difficulty in producing stable designs. In this work, we bring together these different approaches into an integrated tracking framework and show that RVQ tracking performs best according to multiple criteria on publicly available datasets. Moreover, an advantage of our approach is a learning-based tracker that builds the target model while it tracks, thus avoiding the costly step of building target models prior to tracking.

Full textAbstract:
The main goal of this research is to design an efficient compression al~
gorithm for fingerprint images. The wavelet transform technique is the
principal tool used to reduce interpixel redundancies and to obtain a parsimonious
representation for these images. A specific fixed decomposition
structure is designed to be used by the wavelet packet in order to save on the
computation, transmission, and storage costs. This decomposition structure
is based on analysis of information packing performance of several decompositions,
two-dimensional power spectral density, effect of each frequency
band on the reconstructed image, and the human visual sensitivities. This
fixed structure is found to provide the "most" suitable representation for
fingerprints, according to the chosen criteria.
Different compression techniques are used for different subbands, based
on their observed statistics. The decision is based on the effect of each subband
on the reconstructed image according to the mean square criteria as
well as the sensitivities in human vision. To design an efficient quantization
algorithm, a precise model for distribution of the wavelet coefficients is developed.
The model is based on the generalized Gaussian distribution. A least
squares algorithm on a nonlinear function of the distribution model shape
parameter is formulated to estimate the model parameters. A noise shaping
bit allocation procedure is then used to assign the bit rate among subbands.
To obtain high compression ratios, vector quantization is used. In this
work, the lattice vector quantization (LVQ) is chosen because of its superior
performance over other types of vector quantizers. The structure of a lattice
quantizer is determined by its parameters known as truncation level and scaling
factor. In lattice-based compression algorithms reported in the literature
the lattice structure is commonly predetermined leading to a nonoptimized
quantization approach. In this research, a new technique for determining the
lattice parameters is proposed. In the lattice structure design, no assumption
about the lattice parameters is made and no training and multi-quantizing
is required. The design is based on minimizing the quantization distortion
by adapting to the statistical characteristics of the source in each subimage.

Abstract Abstract
Since LVQ is a multidimensional generalization of uniform quantizers, it
produces minimum distortion for inputs with uniform distributions. In order
to take advantage of the properties of LVQ and its fast implementation,
while considering the i.i.d. nonuniform distribution of wavelet coefficients,
the piecewise-uniform pyramid LVQ algorithm is proposed. The proposed
algorithm quantizes almost all of source vectors without the need to project
these on the lattice outermost shell, while it properly maintains a small codebook
size. It also resolves the wedge region problem commonly encountered
with sharply distributed random sources. These represent some of the drawbacks
of the algorithm proposed by Barlaud [26). The proposed algorithm
handles all types of lattices, not only the cubic lattices, as opposed to the algorithms
developed by Fischer [29) and Jeong [42). Furthermore, no training
and multiquantizing (to determine lattice parameters) is required, as opposed
to Powell's algorithm [78).
For coefficients with high-frequency content, the positive-negative mean
algorithm is proposed to improve the resolution of reconstructed images.
For coefficients with low-frequency content, a lossless predictive compression
scheme is used to preserve the quality of reconstructed images. A method
to reduce bit requirements of necessary side information is also introduced.
Lossless entropy coding techniques are subsequently used to remove coding
redundancy.
The algorithms result in high quality reconstructed images with better
compression ratios than other available algorithms. To evaluate the proposed
algorithms their objective and subjective performance comparisons
with other available techniques are presented.
The quality of the reconstructed images is important for a reliable identification.
Enhancement and feature extraction on the reconstructed images
are also investigated in this research. A structural-based feature extraction
algorithm is proposed in which the unique properties of fingerprint textures
are used to enhance the images and improve the fidelity of their characteristic
features. The ridges are extracted from enhanced grey-level foreground areas
based on the local ridge dominant directions. The proposed ridge extraction
algorithm, properly preserves the natural shape of grey-level ridges as well as
precise locations of the features, as opposed to the ridge extraction algorithm
in [81). Furthermore, it is fast and operates only on foreground regions, as
opposed to the adaptive floating average thresholding process in [68). Spurious
features are subsequently eliminated using the proposed post-processing
scheme.

More specifically, we aim at providing one the possibility to explore such image collections, either to extract some kind of information and knowledge, or to wander in the collections. 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

Full textAbstract:
This biomedical engineering thesis explores the opportunities and challenges of 2D+t contrast echocardiography for left ventricle functional analysis, both clinically and within a computer vision atlas-based deformable template model framework. A database was created for the experiments in this thesis, with 21 studies of contrast Dobutamine Stress Echo, in all 4 principal planes. The database includes clinical variables, human expert hand-traced myocardial contours and visual scoring. First the problem is studied from a clinical perspective. Quantification of endocardial global and local function using standard measures shows expected values and agreement with human expert visual scoring, but the results are less reliable for myocardial thickening. Next, the problem of segmenting the endocardium with a computer is posed in a standard landmark and atlas-based deformable template model framework. The underlying assumption is that these models can emulate human experts in terms of integrating previous knowledge about the anatomy and physiology with three sources of information from the image: texture, geometry and kinetics. Probabilistic atlases of contrast echocardiography are computed, while noting from histograms at selected anatomical locations that modelling texture with just mean intensity values may be too naive. Intensity analysis together with the clinical results above suggest that lack of external boundary definition may preclude this imaging technique for appropriate measuring of myocardial thickening, while endocardial boundary definition is appropriate for evaluation of wall motion. Geometry is presented in a Principal Component Analysis (PCA) context, highlighting issues about Gaussianity, the correlation and covariance matrices with respect to physiology, and analysing different measures of dimensionality. A popular extension of deformable models ---Active Appearance Models (AAMs)--- is then studied in depth. Contrary to common wisdom, it is contended that using a PCA texture space instead of a fixed atlas is detrimental to segmentation, and that PCA models are not convenient for texture modelling. To integrate kinetics, a novel spatio-temporal model of cardiac contours is proposed. The new explicit model does not require frame interpolation, and it is compared to previous implicit models in terms of approximation error when the shape vector changes from frame to frame or remains constant throughout the cardiac cycle. Finally, the 2D+t atlas-based deformable model segmentation problem is formulated and solved with a gradient descent approach. Experiments using the similarity transformation suggest that segmentation of the whole cardiac volume outperforms segmentation of individual frames. A relatively new approach ---the inverse compositional algorithm--- is shown to decrease running times of the classic Lucas-Kanade algorithm by a factor of 20 to 25, to values that are within real-time processing reach.

The aim of the doctoral thesis focuses on the static and dynamic analysis of a plan curved cable stayed and suspension pedestrian bridges suspended on a single-side of their deck. The first part of this thesis deals with an analysis of the equilibrium in the transversal direction of a deck cross section suspended on a single-side. The section and its arrangement should be designed so that the torsion caused by the deck self-weight and dead load would be minimal. This theory was verified on a simple study of a single-sided suspended section with and without prestressing. Second part of the thesis deals with the design of a study of a plan curved cable stayed pedestrian bridge. The study describes in detail a finding of an initial state of the structure and the static and dynamic analysis performed by software ANSYS. The static analysis describes the response of the structure on the most frequent variable loads only, but not design of dimensioning according to the valid codes. The dynamic analysis verifies a predisposition of the structure to the vibrations and others harmful oscillation effects. The next objective of the thesis was to design a study of a plan curved suspension pedestrian bridge suspended on a single-side. A process of an analysis of these structures has not found in any available references. Especially, the finding of an initial state of a suspension cable has not been documented anywhere and by anybody. The study was analyzed with the same geometry as the cable stayed variation in order to compare both structures. The static and dynamic analysis was performed, too. The last part of the thesis describes the verification of structural solution on a fully functional model in a 1:10 scale, proposed process of the initial state finding, response of the structures on the loading and ultimate load test. The important step is the comparison of the results of the completed physical model and the calculation model.

Full textAbstract:
This work presents four new methods for the analysis and visualization of tensor fields. The focus is on tensor fields which arise in the context of structural mechanics simulations.
The first method deals with the design of components made of short fiber reinforced polymers using injection molding. The stability of such components depends on the fiber orientations, which are affected by the production process. For this reason, the stresses under load as well as the fiber orientations are analyzed. The stresses and fiber orientations are each given as tensor fields. For the analysis four features are defined. The features indicate if the component will resist the load or not, and if the respective behavior depends on the fiber orientation or not. For an in depth analysis a glyph was developed, which shows the admissible fiber orientations as well as the given fiber orientation. With these visualizations the engineer can rate a given fiber orientation and gets hints for improving the fiber orientation.
The second method depicts gradients of stress tensors using glyphs. A thorough understanding of the stress gradient is desirable, since there is some evidence that not only the stress but also its gradient influences the stability of a material. Gradients of stress tensors are third order tensors, the visualization is therefore a great challenge and there is very little research on this subject so far.
The objective of the third method is to analyse the complete invariant part of the tensor field. Scalar invariants play an important role in many applications, but proper selection of such invariants is often difficult. For the analysis of the complete invariant part the notion of 'extremal point' is introduced. An extremal point is characterized by the fact that there is a scalar invariant which has a critical point at this position. Moreover it will be shown that the extrema of several common invariants are contained in the set of critical points.
The fourth method presented in this work uses the Heat Kernel Signature (HKS) for the visualization of tensor fields. The HKS is computed from the heat kernel and was originally developed for surfaces. It characterizes the metric of the surface under weak assumptions. i.e. the shape of the surfaces is determined up to isometric deformations. The fact that every positive definite tensor field can be considered as the metric of a Riemannian manifold allows to apply the HKS on tensor fields.

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 pictorial elements of the first six books of the
Aeneid can be evidenced through an examination of its
structural components. With commentaries on such
literary devices as parallels and antipodes, interwoven
themes, cyclic patterns, and strategic placement of words
in the text, three genres of painting are treated
individually in Chapter 1 to illustrate the poet's
consistency of design and to prove him a craftsman of the
visual arts.
In the first division, "Cinematic progression," attention
is directed to the language which conveys movement and
frequentative action, with special emphasis placed on
specific passages whose verbal components possess
sculptural or third-dimensional traits and contribute to
the "spiral" and "circle" motifs, the appropriate visual
agents for animation.
Depiction of mythological subjects comprises the second
division entitled "Cameos and snapshots." Three
selections, dubbed monstra, are explicated with such
cross references as to illustrate the poet's use of
epithets which he distributes passim to elicit verbal
echoes of other passages.
The final division, "The Vergilian landscape," addresses
two major themes, antithetical in nature, the martial and
the pastoral. Their sequential juxtaposition in the text
renders a marked contrast in mood which is manifested
pictorially in the transition from darkness to light. A
panoramic chiaroscuro emerges which is the tapestry
against which Aeneas makes his sojourn through the
Underworld. It is the perfect backdrop to accompany the
overriding theme of "things hidden," res latentes, which
encompasses a greater part of the epic and becomes the
culminant motif of the paintings which comprise the
visual presentation.
Chapter 2 functions as a catalogue raisonne for art
inspired by the Aeneid from early antiquity up to the
present day. Such examples of artistic expression
provide a continuum with which to appropriate Horace's
maxim, ut pictura poesis, in their evaluation.
The verbal exegeses in Chapter 1 have been programmed to
comport with the thematic content of the visual
presentation in Chapter 3, a critique exemplifying the
transposition of the verbal to the pictorial. With these
canvases I have attempted to render a new perspective of
Vergil's epic in the genre of abstract expressionism.Art

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.

Visual perception is a psychological construct that describes the awareness of visual sensations and arise from the interactions of the individual or observer in the external environment together with the physiology of the observer’s visual system. A variety of theories of the development of visual perception have led to the development of different psychometric measures aimed at quantifying the cognitive construct. The Visual Perceptual Aspects Test was developed by Clutten (2009) to measure nine different constructs of visual perception. The original VPAT was validated using content and construct validity based on a Western Cape sample. However, to the researcher’s knowledge, a factor analysis had not yet been conducted on the VPAT to determine the factor validity of the test. Furthermore, no measures of validity or reliability had been conducted on the VPAT using a sample outside of the Western Cape. The aim of this research is to validate the hypothesised nine factor structure of the Visual Perceptual Aspects Test, using a confirmatory factor analysis, exploratory structural equation model, a bifactor confirmatory factor analysis and a bifactor exploratory structural equation model. The results of the analysis showed marginal model fit of the VPAT with the sample data, with sufficient levels of reliability for certain sub-tests. However, the VPAT did not meet significant levels of validity or reliability of the proposed model structure of the VPAT for the sample group of learners based in the Eastern Cape.Psychology

Adjacent precast,
prestressed box beam bridges have a history of poor performance and have been
observed to exhibit common types of deterioration including longitudinal
cracking, concrete spalling, and deterioration of the concrete top flange. The nature of these types of deterioration
leads to uncertainty of the extent and effect of deterioration on structural
behavior. Due to limitations in previous
research and understanding of the strength of deteriorated box beam bridges,
conservative assumptions are being made for the assessment and load rating of
these bridges. Furthermore, the design
of new box beam bridges, which can offer an efficient and economical solution,
is often discouraged due to poor past performance. Therefore, the objective of this research is
to develop improved recommendations for the inspection, load rating, and design
of adjacent box beam bridges. Through a
series of bridge inspections, deteriorated box beams were identified and
acquired for experimental testing. The
extent of corrosion was determined through visual inspection, non-destructive
evaluation, and destructive evaluation.
Non-destructive tests (NDT) included the use of connectionless
electrical pulse response analysis (CEPRA), ground penetrating radar (GPR), and
half-cell potentials. The deteriorated
capacity was determined through structural testing, and an analysis procedure
was developed to estimate deteriorated behavior. A rehabilitation procedure was also developed
to restore load transfer of adjacent beams in cases where shear key failures
are suspected. Based on the
understanding of deterioration developed through study of deteriorated adjacent
box beam bridges, improved inspection and load rating procedure are provided along
with design recommendations for the next generation of box beam bridges.

Full textAbstract:
abstract: Texture analysis plays an important role in applications like automated pattern inspection, image and video compression, content-based image retrieval, remote-sensing, medical imaging and document processing, to name a few. Texture Structure Analysis is the process of studying the structure present in the textures. This structure can be expressed in terms of perceived regularity. Our human visual system (HVS) uses the perceived regularity as one of the important pre-attentive cues in low-level image understanding. Similar to the HVS, image processing and computer vision systems can make fast and efficient decisions if they can quantify this regularity automatically. In this work, the problem of quantifying the degree of perceived regularity when looking at an arbitrary texture is introduced and addressed. One key contribution of this work is in proposing an objective no-reference perceptual texture regularity metric based on visual saliency. Other key contributions include an adaptive texture synthesis method based on texture regularity, and a low-complexity reduced-reference visual quality metric for assessing the quality of synthesized textures. In order to use the best performing visual attention model on textures, the performance of the most popular visual attention models to predict the visual saliency on textures is evaluated. Since there is no publicly available database with ground-truth saliency maps on images with exclusive texture content, a new eye-tracking database is systematically built. Using the Visual Saliency Map (VSM) generated by the best visual attention model, the proposed texture regularity metric is computed. The proposed metric is based on the observation that VSM characteristics differ between textures of differing regularity. The proposed texture regularity metric is based on two texture regularity scores, namely a textural similarity score and a spatial distribution score. In order to evaluate the performance of the proposed regularity metric, a texture regularity database called RegTEX, is built as a part of this work. It is shown through subjective testing that the proposed metric has a strong correlation with the Mean Opinion Score (MOS) for the perceived regularity of textures. The proposed method is also shown to be robust to geometric and photometric transformations and outperforms some of the popular texture regularity metrics in predicting the perceived regularity. The impact of the proposed metric to improve the performance of many image-processing applications is also presented. The influence of the perceived texture regularity on the perceptual quality of synthesized textures is demonstrated through building a synthesized textures database named SynTEX. It is shown through subjective testing that textures with different degrees of perceived regularities exhibit different degrees of vulnerability to artifacts resulting from different texture synthesis approaches. This work also proposes an algorithm for adaptively selecting the appropriate texture synthesis method based on the perceived regularity of the original texture. A reduced-reference texture quality metric for texture synthesis is also proposed as part of this work. The metric is based on the change in perceived regularity and the change in perceived granularity between the original and the synthesized textures. The perceived granularity is quantified through a new granularity metric that is proposed in this work. It is shown through subjective testing that the proposed quality metric, using just 2 parameters, has a strong correlation with the MOS for the fidelity of synthesized textures and outperforms the state-of-the-art full-reference quality metrics on 3 different texture databases. Finally, the ability of the proposed regularity metric in predicting the perceived degradation of textures due to compression and blur artifacts is also established.Dissertation/Thesis

No âmbito do direito de acesso à justiça, o fenómeno da autorrepresentação está a tornar-se um elemento estrutural na prática judiciária dos processos judiciais cíveis de primeira instância. No contexto da autorrepresentação, a elaboração de uma petição inicial coerente e a predominância da forma de comunicação verbal são duas variáveis que condicionam a interação dos litigantes, em autorrepresentação, com o sistema judicial.
Esta investigação incide na construção de formas alternativas à representação verbal da petição inicial em processos judiciais de baixa complexidade, tendo por hipótese que é possível descrever um conflito através duma narrativa visual, de forma coerente, sem prejuízo da precisão e do rigor, garantias fundamentais no processo judicial.
Deste modo, e assumindo que o litigante autorrepresentado não tem os conhecimentos técnicos necessários para elaborar uma petição inicial coerente, nesta investigação são propostos um modelo de coerência estrutural de uma petição visual – que facilite a elaboração de uma descrição coerente da petição inicial, na forma visual, para processos cíveis de baixa complexidade – e um método de análise da coerência de uma petição visual.
Para avaliar o modelo de coerência estrutural e o correspondente método de análise, foi desenvolvido um procedimento pormenorizado e sistemático, através de uma abordagem experimental. O conjunto de resultados empíricos obtidos mostra, com alguma evidência, que um litigante em autorrepresentação, sem conhecimentos específicos na elaboração de uma petição inicial, consegue construir uma petição inicial coerente através de uma narrativa visual baseada no modelo de coerência estrutural proposto.Dans 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.

Full textAbstract:
The 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 textAbstract:
Very large graphs are difficult for a person to browse and edit on a computer screen. This thesis introduces a visual formalism, structured graphs, which supports the scalable browsing and editing of very large graphs. This approach is relevant to a given application when it incorporates a large graph which is composed of named nodes and links, and abstraction hierarchies which can be defined on these nodes and links. A typical browsing operation is the selection of an arbitrary group of nodes and the display of the network of nodes and links for these nodes. Typical editing operations is: adding a new link between two nodes, adding a new node in the hierarchy, and moving sub-graphs to a new position in the node hierarchy. These operations are scalable when the number of user steps involved remains constant regardless of how large the graph is. This thesis shows that with structured graphs, these operations typically take one user step. We demonstrate the utility of structured graph formalism in an application setting. Computer aided software engineering tools, and in particular, structured analysis tools, are the chosen application area for this thesis, as they are graph based, and existing tools, though adequate for medium sized systems, lack scalability. In this thesis examples of an improved design for a structured analysis tool, based on structured graphs, is given. These improvements include scalable browsing and editing operations to support an individual software analyst, and component composition operations to support the construction of large models by a group of software analysts. Finally, we include proofs of key properties and descriptions of two text based implementations.

Full textAbstract:
Communication is an essential component of animal social systems and a diverse suite of signals can be found in the natural environment. An area of animal communication that, for technical reasons, we know very little about is the field of ‘movement-based’ or ‘dynamic’ visual signals. In this thesis, I make use of recent advances in measurement and analysis techniques, including digital video and image motion processing tools, to improve our understanding of how movement-based signals are adjusted according to signalling context. I measured and characterised the flamboyant claw-waving displays of male fiddler crabs (Genus Uca) and made use of their transparent lifestyle to record the behavioural contexts in which these signals are produced.
The claw-waving displays of seven Australian species of fiddler crab are compared and contrasted to show that these signals are species-specific, but also vary within and between individuals. I show that the species Uca perplexa produces different types of signal in different behavioural contexts, a lateral wave for courtship, and a vertical wave during short-range agonistic and courtship interactions. The structure of the lateral courtship waves of Uca perplexa vary according to the distance of signal receivers, the first time this kind of relationship has been shown in a dynamic visual signal. Finally, I describe and analyse the signalling and orientation behaviour of U. elegans during courtship herding, an unusual mating system that uses the claw-waving display in a novel way.¶
The adjustments made by fiddler crabs to their displays during changes in behavioural contexts suggest that the fine-scale context-sensitivity of animal signals may be far more widespread in communication than hitherto recognised.

Dissertação de mestrado integrado em Engenharia e Gestão de Sistemas de InformaçãoA 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 textAbstract:
During the past several decades, earthquakes have caused extensive damage to
buildings, including wood-frame, single-family dwellings, in the United States. In
order to mitigate future losses, existing buildings in earthquake prone areas should be
evaluated for their seismic safety. This is also an important issue for buildings in
Oregon due to the Cascadia subduction zone along its west coast.
One seismically vulnerable element observed in wood-frame, single-family dwellings
is the shear walls. In general, assessment of shear wall seismic performance can be
accomplished by a building-specific engineering calculation. Extra effort is required if
the effects of plan irregularity are a concern. This project aims to facilitate seismic
evaluation of wood-frame dwellings by proposing a new engineering-based rapid
visual screening method to examine the expected performance level of the structure's
exterior shear walls to resist lateral forces from ground motions, including torsional
forces induced from plan irregularity.
In order to achieve the objective, SAPWood software was used to perform a series of
nonlinear time-history analyses for 480 representative models, covering different
combinations of shape parameters and shear wall opening-related parameters. The evolutionary parameter hysteresis model was used to represent the load-displacement
relationship of structural panel-sheathed shear walls and a ten parameter CUREE
hysteresis model for gypsum wallboard sheathed walls. The calculated maximum
lateral drifts were used as basic information for the development of the new method.
Through the development process, the significance of both plan configuration and
shear wall openings were emphasized as they affect the overall seismic performance
of a building through building mass, lateral stiffnesses, and eccentricities. Within the
study range, single-family dwellings with two stories, a larger percentage of openings,
and having a garage door were shown to be more vulnerable to seismic events. Plan
configuration and shear wall openings were important features especially in houses
located in high 1 (0.5g ≤ S[subscript a] < 1.0g) and high 2 (1.0g ≤ S[subscript a] < 1.5g) seismicity regions, as
they could potentially lead to severe damage. For low and moderate seismicity, the
performance ranges from satisfying the collapse prevention limit to the immediate
occupancy limit.
The developed piRVS (plan irregularity Rapid Visual Screening) takes into
consideration the shape of the floor plan, number of stories, base rectangular area,
percent cutoff, and openings from doors/windows and garage doors, and supports
evaluation at the immediate occupancy (IO), life safety (LS), and collapse prevention
(CP) performance levels. The piRVS provides relatively more conservative
assessment results than FEMA 154 and ASCE 31 Tier 1. Its prediction for the two
applicable Northridge earthquake damage samples is reasonable. This method will
help architects, engineers, building officials, and trained inspectors in examining the
expected seismic performance of shear walls, considering the effects of plan
irregularity in wood-frame, single-family dwellingsGraduation date: 2012

The master's thesis deals with the citizen photojournalism and the citizen videojournalism in the Czech media landscape. It focuses on the frequency of the amateur photographs and videos published on the selected news web sites and also on the gatekeeping process. This master's thesis also reflects the editor's opinions on the citizen photojournalism and the citizen videojournalism. The citizen journalism is usually viewed from the perspective of the citizen journalists, but this master's thesis brings the view from the second side, from the media professionals. The thesis uses the combination of the quantitative and qualitative methods. Firstly, there was conducted the quantitative content analysis. Secondly, there were interviewed the media professionals. The conclusions of the master's thesis indicate that the citizen photojournalism and the citizen videojournalism is rarely used on the Czech web sites. The media professionals evaluate this phenomenon positively, find its contributions to the news flow but only under the certain conditions. On the other hand, they do not find the citizen photojournalism and videojournalism absolutely necessary element for the news service.
