Numerical Analysis of the Behavior of Compacted and Natural Unsaturated Tropical Soils
(Ios Press, 2019-01-01)
Several regions of countries with tropical climate exhibit alternation between dry and rainy seasons and, these countries also exhibit geological processes that create ideal conditions for the formation of thick layers of ...
Numerical Studies of Premixed and Diffusion Meso/Micro-Scale Flames
(2017-01-01)
This work reports a numerical investigation of premixed and diffusion meso/micro-scale flames, with homogeneous reactions, for two different cases involving CH4/air premixed dynamics flames and co-flow diffusion flame with ...
Transmission lines model with different basic structures applied to transient electromagnetic simulations
(2016-01-01)
Models based on lumped elements are simple ones to represent systems composed by distributed parameters when models with lumped elements use a lot of these elements. However, such mentioned models usually present numerical ...
Disconnected Handwritten Numeral Image Recognition
(IEEE, Los Alamitos, CA, United States, 1997)
A new implementation of Population Based Incremental Learning method for optimization studies in electromagnetics
(2006-11-21)
To enhance the global search ability of Population Based Incremental Learning (PBIL) methods, It Is proposed that multiple probability vectors are to be Included on available PBIL algorithms. As a result, the strategy for ...
EVALUATION OF NUMERICAL METHODS APPLIED IN THE ANALYSIS OF THE TRANSIENT FLOW OF PIPELINE SYSTEMS
(Amer Soc Mechanical Engineers, 2013-01-01)
Brazilian subsea exploration is increasing specially after the post salt petroleum field discovery. Several challenges have been imposed for the production of those fields. In this scenery, the transport of oil and gas ...

(2012-12-01)
Brazilian subsea exploration is increasing specially after the post salt petroleum field discovery. Several challenges have been imposed for the production of those fields. In this scenery, the transport of oil and gas ...
Numerical and experimental analysis of natural convection in a cavity heated from below
(Taylor & Francis Ltd, 1998-01-01)
In this work, an analysis of the natural convection flow caused by heat sources dissipating energy at a constant rate simulating electronic components mounted at the bottom surface of a cavity symmetrically cooled from the ...
Numerical analysis of roll waves generation on non-Newtonian fluids flowing down an inclined plane
(2014-01-01)
This article aims to determine roll waves generation criteria for mudflow events. A representative system of equations to mudflows is reached through Cauchy's equations (mass and momentum conservation) with proper stress ...
Another prefiltering algorithm for adaptive IIR filtering
(1995-12-01)
An algorithm for adaptive IIR filtering that uses prefiltering structure in direct form is presented. This structure has an estimation error that is a linear function of the coefficients. This property greatly simplifies ...
