Deep Learning of Neuromuscular Control for Biomechanical Human Animation
Deep Learning of Neuromuscular Control For Biomechanical Human Animation Masaki Nakada? and Demetri Terzopoulos Computer Science Department University of California, Los Angeles Abstract. Increasingly complex physics-based models enhance the real- ism of character animation in computer graphics, but they pose difficult motor control challenges. This is especially the case when controlling a biomechanically simulated virtual human with an anatomically real- istic structure that is actuated in a natural manner by a multitude of contractile muscles. Graphics researchers have pursued machine learn- ing approaches to neuromuscular control, but traditional neural network learning methods suffer limitations when applied to complex biomechan- ical models and their associated high-dimensional training datasets. We demonstrate that \deep learning" is a useful approach to training neu- romuscular controllers for biomechanical character animation. In par- ticular, we propose a deep neural network architecture that can effec- tively and efficiently control (online) a dynamic musculoskeletal model of the human neck-head-face complex after having learned (offline) a high-dimensional map relating head orientation changes to neck muscle activations. To our knowledge, this is the first application of deep learn- ing to biomechanical human animation with a muscle-driven model. 1 Introduction The modeling of graphical characters based on human anatomy is becoming increasingly important in the field of computer animation. Progressive fidelity in biomechanical modeling should, in principle, result in more realistic human animation. Given realistic biomechanical models, however, we must confront a variety of difficult motor control problems due to the complexity of human anatomy. In conjunction with the modeling of skeletal muscle [1,2], existing work in biomechanical human modeling has addressed the hand [3,4,5], torso [6,7,8], face [9,10,11], neck [12], etc. -
Novels of Return
Novels of Return: Ethnic Space in Contemporary Greek-American and Italian-American Literature by Theodora D. Patrona A dissertation submitted to the Department of American Literature and Culture, School of English, Faculty of Philosophy, In fulfilment of the requirements for the degree of Doctor of Philosophy Aristotle University of Thessaloniki, Greece February 2011 i στην οικογένειά μου, Ελισάβετ, Δημήτρη και Λεωνίδα που ενθάρρυνε και υποστήριξε αυτό το «ταξίδι» με όλους τους πιθανούς τρόπους… και στον Μάνο μου, που ήταν πάντα εκεί ξεπερνώντας τις δυσκολίες… ii Acknowledgements This thesis would not have been possible without the inspiration, support and kind help of numerous people. Firstly, my advisor, mentor, and, I dare say, friend, Professor Yiorgos Kalogeras who has always been my most enthusiastic supporter, guiding me with his depths of knowledge in ethnic literature, unfailingly encouraging me to keep going, and consoling me whenever I was disappointed. He has opened his home, his family and circle of scholarly friends, which I appreciate immensely. I would also like to warmly thank the other two members of my committee, Drs. Yiouli Theodosiadou and Nikolaos Kontos for their patience, feedback, thoroughness, and encouraging comments on my work. Moreover, I am indebted to Professor Fred Gardaphé who has welcomed me in the Italian-American literature and scholarship, pointing out new creative paths and outlets. All these years of research, I have been constantly assisted, advised and reassured by my Italian mentor and true friend, Professor Stefano Luconi without whom this dissertation would lack its Italian-American part, and would have probably been left incomplete every time I lost hope. -

We introduce tiny- graphics.js, a new software library for implementing educational WebGL projects in the classroom. To mitigate the difficulty of creating graphics-enabled websites and online games, we furthermore introduce the Encyclopedia of Code|a world wide web framework that encourages visitors to learn graphics, build educational graphical demos and articles, host them online, and organize them by topic. We provide our own examples that include custom educational games and tutorial articles, which are already being successfully employed to ease our undergraduate graphics students into the course material. Some of our modules expose students to new graphics techniques, while others are prototypes for new modes of online learning, collaboration, and computing. These include our \Active Textbooks" (educational 3D demos or games embedded in literate-programming-like articles). -
The Representation of Suicide in the Cinema
The Representation of Suicide in the Cinema John Saddington Submitted for the degree of PhD University of York Department of Sociology September 2010 Abstract This study examines representations of suicide in film. Based upon original research cataloguing 350 films it considers the ways in which suicide is portrayed and considers this in relation to gender conventions and cinematic traditions. The thesis is split into two sections, one which considers wider themes relating to suicide and film and a second which considers a number of exemplary films. Part I discusses the wider literature associated with scholarly approaches to the study of both suicide and gender. This is followed by quantitative analysis of the representation of suicide in films, allowing important trends to be identified, especially in relation to gender, changes over time and the method of suicide. In Part II, themes identified within the literature review and the data are explored further in relation to detailed exemplary film analyses. Six films have been chosen: Le Feu Fol/et (1963), Leaving Las Vegas (1995), The Killers (1946 and 1964), The Hustler (1961) and The Virgin Suicides (1999). These films are considered in three chapters which exemplify different ways that suicide is constructed. Chapters 4 and 5 explore the two categories that I have developed to differentiate the reasons why film characters commit suicide. These are Melancholic Suicide, which focuses on a fundamentally "internal" and often iII understood motivation, for example depression or long term illness; and Occasioned Suicide, where there is an "external" motivation for which the narrative provides apparently intelligible explanations, for instance where a character is seen to be in danger or to be suffering from feelings of guilt. -
Snakes: Active Contour Models
International Journal of Computer Vision, 321-331 (1988) o 1987 KIuwer Academic Publishers, Boston, Manufactured in The Netherlands Snakes: Active Contour Models MICHAEL KASS, ANDREW WITKIN, and DEMETRI TERZOPOULOS Schlumberger Palo Alto Research, 3340 Hillview Ave., Palo Alto, CA 94304 Abstract A snake is an energy-minimizing spline guided by external constraint forces and influenced by image forces that pull it toward features such as lines and edges. Snakes are active contour models: they lock onto nearby edges, localizing them accurately. Scale-space continuation can be used to enlarge the cap- ture region surrounding a feature. Snakes provide a unified account of a number of visual problems, in- cluding detection of edges, lines, and subjective contours; motion tracking; and stereo matching. We have used snakes successfully for interactive interpretation, in which user-imposed constraint forces guide the snake near features of interest. 1 Introduction organizations.

American Book Awards 2004
BEFORE COLUMBUS FOUNDATION PRESENTS THE AMERICAN BOOK AWARDS 2004 America was intended to be a place where freedom from discrimination was the means by which equality was achieved. Today, American culture THE is the most diverse ever on the face of this earth. Recognizing literary excel- lence demands a panoramic perspective. A narrow view strictly to the mainstream ignores all the tributaries that feed it. American literature is AMERICAN not one tradition but all traditions. From those who have been here for thousands of years to the most recent immigrants, we are all contributing to American culture. We are all being translated into a new language. BOOK Everyone should know by now that Columbus did not “discover” America. Rather, we are all still discovering America—and we must continue to do AWARDS so. The Before Columbus Foundation was founded in 1976 as a nonprofit educational and service organization dedicated to the promotion and dissemination of contemporary American multicultural literature. The goals of BCF are to provide recognition and a wider audience for the wealth of cultural and ethnic diversity that constitutes American writing. BCF has always employed the term “multicultural” not as a description of an aspect of American literature, but as a definition of all American litera- ture. BCF believes that the ingredients of America’s so-called “melting pot” are not only distinct, but integral to the unique constitution of American Culture—the whole comprises the parts. In 1978, the Board of Directors of BCF (authors, editors, and publishers representing the multicultural diversity of American Literature) decided that one of its programs should be a book award that would, for the first time, respect and honor excellence in American literature without restric- tion or bias with regard to race, sex, creed, cultural origin, size of press or ad budget, or even genre. -
