A new method is described for determining the values of the level function from a given interface that is to be represented exactly as the zero level set. The level function is linear on boundary segments of the grid cells, which precludes the definition of the level function on the grid nodes as the signed distance from the interface. Instead, the values of the level function on a strip along ...

We construct a novel fully-decoupled and second-order accurate time marching numerical scheme with unconditional energy stability for the Cahn–Hilliard–Darcy phase-field model of two-phase Hele–Shaw flow, in which, key idea to realize full decoupling structure is use so-called “zero-energy-contribution” function design special ordinary differential equation deal nonlinear coupling terms between...

We present an in-depth analysis of the sources variance in state-of-the-art unbiased volumetric transmittance estimators, and propose several new methods for improving their efficiency. These combine to produce a single estimator that is universally optimal relative prior work, with up orders magnitude lower at same cost, has zero any ray non-varying extinction. first reduce truncated power-ser...

objective: the aim of this study was to examine the differences between adhd subtypes in executive function tasks compared to themselves and normal controls. method: in this study, 45 school aged children with attention deficit hyperactivity disorder (adhd) and 30 normal children who were matched based on age and iq score in wechsler intelligence scale for children-revised (wisc-r) were compare...

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 ...
