Many methods have been proposed that model the characteristics of light for producing realistic computer generated images in recent years. However, these aproaches are not adapted to take into account the typical properties of "any" light source and material. In order to generate simulations for industrial applications, as in the lighting industry, these emittance and reeectance properties have...

This paper proposes a state-of-the-art method of digital-audio watermarking, based on the properties of the human cochlear. It is based on the concept of embedding inaudible watermarks (e.g., copyright data) into an original sound by controlling the phase characteristics of the sound in relation to the characteristics of cochlear delay. The method involves two processes, i.e., embedding and det...

A new kind of comprehensive evaluation method is proposed through analyzing the characteristics of the source of information. We use of three kinds of information transmission network performance report of the son from a source for information. Exploring the effective information diffusion characteristics, we analyzed the characteristics. The results in these characteristics have different char...

In previous work, a new adaptive meshfree advection scheme for numerically solving linear transport equations has been proposed. The scheme, being a combination of an adaptive semi-Lagrangian method and local radial basis function interpolation, is essentially a method of backward characteristics. The adaptivity of the meshfree advection scheme relies on customized rules for the refinement and ...

Neighbourhood interactions between land use types are often included in the spatially explicit analysis of land use change. Especially in the context of urban growth, neighbourhood interactions are often addressed both in theories for urban development and in dynamic models of (urban) land use change. Neighbourhood interactions are one of the main driving factors in a large group of land use ch...

JOHN WRIGHT This has been evolved with a modified pulse duplicator and the use of a hot film probe for measuring velocity, direction, and turbulence. Many of the commercially available mitral valve prostheses are being investigated for their flow characteristics. In addition, efficiency is being examined and some unusual findings point to the possibility of a hydraulic ram effect in the normal ...

Turbulent flows are the most applicable cases that in recent years the researches have been focused on developing of solution methods. Incompressible turbulent flow is one of these cases which need to be taken in account. Solving the incompressible Navier-stokes equation because of elliptical characteristics has been led to some researches in this field recently. The ACM of Chorin [1] as a pre-...

Understanding the dynamics and the stabilisation of flames is important for practical applications and for theoretical research. Here, to investigate the time-evolution of a Bunsen flame in a Poiseuille flow, we extend a G-equation-based kinematic model by accounting for flame stabilisation. The nonlinear G-equation is solved analytically using the methods of characteristics. The solution is th...
