We propose an efficient model for the description of three-dimensional (3-D) evolution breaking water waves in nearshore region. A fundamental property is its intrinsic ability to account 3-D dynamics vorticity and energy dissipation induced by wave breaking. In particular, achieved through use mollified operators, approach similar spirit that adopted smoothed particle hydrodynamics. Further, s...

The present work solves two-dimensional Advection-Dispersion Equation (ADE) in a semi-infinite domain. A variable source concentration is regarded as the monotonic decreasing function at the source boundary (x=0). Depth-dependent variables are considered to incorporate real life situations in this modeling study, with zero flux condition assumed to occur at the exit boundary of the domain, i.e....

We present a combination of techniques to implement a feature-rich ray tracer that applies adaptive sampling to optimize performance. We build these features upon existing methods in which we experiment with techniques to optimally combine them in a ray tracer.

The depth hierarchy results for monotone circuits of Raz and McKenzie [5] are extended to the case of monotone circuits of semiunbounded fan-in. It follows that the inclusions NC ⊆ SAC ⊆ AC are proper in the monotone setting, for every i ≥ 1. Mathematics Subject Classification. 68Q17, 68Q15.

Microblogging services have brought users to a new era of knowledge dissemination and information seeking. However, the large volume and multi-aspect of messages hinder the ability of users to conveniently locate the specific messages that they are interested in. While many researchers wish to employ traditional text classification approaches to effectively understand messages on microblogging ...

In this paper, we study efficient closed pattern mining in a general framework of set systems, which are families of subsets ordered by set-inclusion with a certain structure, proposed by Boley, Horváth, Poigné, Wrobel (PKDD’07 and MLG’07). By modeling semi-structured data such as sequences, graphs, and pictures in a set system, we systematically study efficient mining of closed patterns. For a...

High-quality depth map generation is a key component of free-viewpoint video (FVV), because the virtual view-point images used for FVV are synthesized from real multi-view images and their depth maps. However, synthesized images do not guarantee good quality if the depth maps are inaccurate. Many studies have been conducted to develop methods for generating accurate depth maps. A semi-automatic...
