In this paper we present a study of the algorithmic and architectural exploration methodology for a parallelism of the 3D reconstructing algorithm (Marching Cubes) and its optimized implementation on FPGA. We aim at defining a parallel multiprocessor architecture implementing this algorithm in an optimal way and Elementary Processor (EP) architecture dedicated to this algorithm. We use the SynD...

In this paper, we present the “Mobile Device Marching Band” (MDMB) as a new mode of musical performance with mobile computing devices. We define an MDMB to be, at its most general, any ensemble utilizing mobile computation that can travel as it performs, with the performance being independent of its location. We will discuss the affordances and limitations of mobile-based instrument design and ...

Proper characterization of uncertainty is a challenging task. Depending on the sources of uncertainty, various uncertainty modeling frameworks have been proposed and studied in the uncertainty quantification literature. This paper applies various uncertainty modeling frameworks, namely possibility theory, Dempster-Shafer theory and probability theory to isosurface extraction from uncertain scal...

We derive a Godunov-type numerical flux for the class of strictly convex, homogeneous Hamiltonians that includes H(p; q) = pap2 + bq2 2 pq; 2 < ab: We combine our Godunov numerical fluxes with a simple GaussSeidel type iterations for solving the corresponding Hamilton-Jacobi Equations. The resulting algorithm is fast since it does not require a sorting strategy as does the fast marching method....

We join the camp of mathematics educators who claim that children should receive early training in stochastic thinking, although their training – at such stage – may only be based on a heuristic understanding of stochastic phenomena. The term “heuristic” is to be taken in the sense propagated by scientists like Einstein and Polya, which is not as “a rule of thumb” but as a correct yet partial a...

Chondrons form the fundamental biomechanical and metabolic unit of articular cartilage. But there is no accurate description of chondron volume which is known to change when articular cartilage is functionally loaded. This report discusses the 3D feature analysis of the confocal microscopy images of chondrons. The basic principle of confocal microscopy is described. The segmentation problem of ...

Digital inpainting provides a means for reconstruction of small damaged portions of an image. Although the inpainting basics are straightforward, most inpainting techniques published in the literature are complex to understand and implement. We present here a new algorithm for digital inpainting based on the fast marching method for level set applications. Our algorithm is very simple to implem...
