FaceEngine a 3D facial animation engine for real time applications

Abstract: This article describes a real time facial animation engine conceived to run on common personal computers with a graphic accelerator board. The ultimate aim is to play several faces on the same computer with an acceptable frame rate. The animation engine has been implemented with both aTTS and a voice segmentation module.

Improving Generalization Level in UML Models Iterative Cross Generalization in Practice

Abstract: FCA has been successfully applied to software engineering tasks such as source code analysis and class hierarchy re-organization. Most notably, FCA puts mathematics behind the mechanism of abstracting from a set of concrete software artifacts. A key limitation of current FCA-based methods is the lack of support for relational information (e.g., associations between classes of a hierarchy): the focus is exclusively on artifact properties whereas inter-artifact relationships may encode crucial information. Consequently, feeding-in relations into the abstraction process may substantially improve its precision and thus open the access to qualitatively new generalizations. In this paper, we elaborate on ICG, an FCA-based methodology for extracting generic parts out of software models that are described as UML class diagrams. The components of ICG are located within the wider map of an FCA framework for relational data. A few experimental results drawn from an industrial project are also reflected on.

Laser component having a bragg reflector of organic material, and a method of making it

Abstract: A laser component having a Bragg reflector, the component comprising a substrate carrying firstly an active emission section of semiconductor materials and secondly a Bragg reflector waveguide extending said active section, means enabling the refractive index of the waveguide to be varied so as to control the wavelength tuning of said laser component, wherein said waveguide is made of organic material(s).

Relation between quantum and geometric dimensionalities in molecular nonlinear optics: beyond the two-level model for anisotropic systems

Abstract: The nonlinear optical susceptibilities of two- or three-dimensional molecular systems exhibit variable anisotropic features depending on their structure and substitution pattern. We show that appropriate geometric (e.g. tensorial) considerations combined with an n-level quantum model (n≥3) are able to account for such nonlinear anisotropy as rigorously defined in an invariant spherical formalism by extension of classical linear anisotropy. We call on two kinds of experiments to investigate these properties: firstly, variation of the incident polarization (VIP) in harmonic light scattering (HLS) experiments is being performed to sort out individual tensorial components of the quadratic hyperpolarizability β tensor; secondly, wavelength dependence studies in coherent second harmonic generation (SHG) from poled thin film media are shown at a preliminary stage to be able to designate those excited states responsible for the nonlinear anisotropy.

Mobile Camera Phones: A New Form of “Being Together” in Daily Interpersonal Communication

Abstract: Roland Barthes concludes his essay “La chambre claire” by stating that “what characterizes so-called advanced societies is the fact that Society consumes images now instead of beliefs.” He writes, “Pleasure is experienced via the image: this is the great difference” (Barthes, 1980). In analyses of the transition from modernism to post-modernism, society’s saturation by images and their increasing impact on relationships between people, things, knowledge, imagination, events and information is essential to understanding cultural and social changes. The “image” industries have been the subject of close examination and endless interpretation. Attention has focused on industries, such as the television industry, advertising and the cinema, and their mass effect. The more intimate role of the image in interpersonal relationships has remained marginal. Put simply, we could say that two key issues in the social sciences are involved here: first, the analysis and study of specular (mirror) images and their imaginary role in the development of the self and the identification process; and second, sociology and ethnography with studies on the social and family-related function of photography following Bourdieu’s definitive study on “the average art” (Garrigues, 1996). However, even in the second domain, there are still very few sociological studies on photography as a social, domestic or everyday practice, possibly because of its status as an artistic practice and as a stylistic and singular representation of the world.
