A two-step interface capturing scheme, implemented within the framework of conservative level set method, is developed in this study to simulate the gas/water two-phase fluid flow. In addition to solving the pure advection equation, which is used to advect the level set function for tracking interface, both nonlinear and stabilized features are taken into account for the level set function so t...

The rapid progress in Virtual Reality technology has demanded more natural and effective human-computer interaction (HCI) for tasks such as display control, navigation and virtual object manipulation. Conventional interface devices such as keyboards and mice are cumbersome to use in Virtual Environments (VE). Bare hand gesturing (especially in combination with speech) is a leading candidate for...

In this paper, the modeling of phase change in an incompressible two-phase flow solver is detailed without restricting numerical methods to a specific interface capturing method. Starting from existing methodologies literature, present work gives step-by-step investigation each aspect obtain accurate and consistent solver. The main challenge when including phase-change handling flux discontinui...

This paper proposes a comparison of four popular interface capturing methods : the volume fluid (VOF), standard level set (SLS), accurate conservative (ACLS) and coupled (CLSVOF). All are embedded into unified low-Mach framework based on Cartesian-grid finite-volume discretization. includes sharp transport interface, well-balanced surface tension discretization consistent mass momentum which al...

Semantic role labels are the representation of the grammatically relevant aspects of a sentence meaning. Capturing the nature and the number of semantic roles in a sentence is therefore fundamental to correctly describing the interface between grammar and meaning. In this paper, we compare two annotation schemes, PropBank and VerbNet, in a task-independent, general way, analysing how well they ...

This paper presents a novel real-time palmprint recognition system for cooperative user applications. This system is the first one achieving noncontact capturing and recognizing palmprint images under unconstrained scenes. Its novelties can be described in two aspects. The first is a novel design of image capturing device. The hardware can reduce influences of background objects and segment out...

In our previous studies into web design, we found that pens, paper, walls, and tables were often used for explaining, developing, and communicating ideas during the early phases of design. These wall-scale paper-based design practices inspired The Designers’ Outpost, a tangible user interface that combines the affordances of paper and large physical workspaces with the advantages of electronic ...
