In this paper, a two-dimensional (2D) rate model is proposed considering the joint impact of spatial (i.e., the frame size) and SNR (i.e., the quantization step) resolutions on the overall rate-distortion performance. A related 2D quality model is then pr... see more

A reliability approach referred to as the point estimate method (PEM) is presented to assess the uncertainty of a two-dimensional hydraulic model. PEM is a special case of numerical quadrature based on orthogonal polynomials, which evaluates the statistic... see more

Bacias hidrográficas montanhosas são mais propensas aos perigos naturais, devido à ocorrência de eventos hidrológicos de alta intensidade e às características geomorfológicas destes locais, como o relevo declivoso e a presença de leques aluviais. O presen... see more

According to the different research platforms of PEMFC (Proton Exchange Membrane Fuel Cell) faults diagnosis, experimental diagnostics and mathematical modeling are employed in the characterization and determination of fuel cell performance. The methods b... see more

The outcome of radio frequency thermal ablation (RFTA) is significantly affected by the tissue electrical conductivity; thus, understanding the changes of this property during heating is fundamental to suitably model the medical procedure. In this work a ... see more

We investigate the effects of non-uniform distribution of constitutive parameters on the dynamic propagation ofan earthquake rupture. We use a 2D finite difference numerical method and we assume that the dynamic rupturepropagation is governed by a rate- a... see more

ABSTRACT: This study is conducted to investigate turbulent natural convection flow in an enclosure with thermal sources using the low-Reynolds number (LRN) k-? model. This enclosure has a cold source with temperature Tc and a hot source with temperature T... see more

This paper discusses numerical methodologies to simulate micro vibrations on a nontrivial torsionally oscillating structure. The torsional structure is the tip of a viscosity-density sensor using micro vibrations to measure the fluid properties. A 2D tran... see more

Most glaciers in China lie in high mountainous environments and have relatively large surface slopes. Common analyses consider glaciers’ projected areas (2D Area) in a two-dimensional plane, which are much smaller than glacier’s topographic surface extent... see more
