CEDRIC Research Report n◦ CEDRIC-14-2906 A new description for scalable 3D partial object retrieval

This paper presents an approach for 3D object retrieval, dedicated to partial shape retrieval in large datasets. A Bag-of-Words representation is employed, based on the extraction of 3D Harris points and on a local description involving local Fourier descriptors. By adding ∆-TSR, a triangular spatial information between words, the richness and robustness of this representation is reinforced. Th...

Electrostatics in Stueckelberg-Horwitz electrodynamics

In this paper, we study fundamental aspects of electrostatics as a special case in Stueckelberg-Horwitz electromagnetic theory. In this theory, spacetime events xμ(τ) evolve in an unconstrained 8-dimensional phase space, interacting through five τ-dependent gauge fields induced by the current densities associated with their evolutions. The chronological time τ was introduced as an independent e...

Computer Interpretable Guidelines (CIG) have largely contributed to the simplification and dissemination of clinical guidelines. However, the formalization of CIG contents, especially care actions, is still an open issue. Actually, this information, which is the heart of the guideline, is still expressed as free text and therefore prevents the development of intelligent tools for assisting phys...

Rick Horwitz: Words do not suffice

Around the turn of the century, the advent of large-scale, collaborative genomic se-quencing efforts greatly accelerated the pace of biomedical research. Genomic data allowed biologists to single out genes and proteins and probe their functional and structural activities. However, scientists still don't have a very good understanding of how different proteins work together in functional complex...
