ENO adaptive method for solving one-dimensional conservation laws
(ELSEVIER SCIENCE BV, 2009)
In this work an efficient third order non-linear finite difference scheme for solving adaptively hyperbolic systems of one-dimensional conservation laws is developed. The method is based oil applying to the solution of the ...
Optimization in ultrasonic imaging systems: Use of metaheuristics to design sparse arrays and a heuristic to create an acquisiton system
(Universidade Estadual Paulista (Unesp), 2022-09-02)
Ultrasonic images have an important contribution to medical diagnosis and nondestructive testing. One strategy to generate an image is to use an array, which is a transducer composed of a set of piezoelectric elements, ...
Algoritmo genético acoplado a um método multi-grid e a teoria dos grafos para determinação da estrutura de equilíbrio de aglomerados atômicos
(Universidade Federal de Santa MariaBRFísicaUFSMPrograma de Pós-Graduação em Física, 2012-12-14)
In this work we present a proposal to improve Genetic Algorithm method by coupling
it to the techniques of discretization of the configurational space via the multi-grid
methodology, and by employing a topological selection ...
Iterative method for detecting and localizing islands within sparse matrixes using DSSim-RT
(2015-07-30)
Nowadays, simulation for power flow analysis of
distribution systems must consider their separation in several
islands. This separation is the result of management activities
such as reconfiguration, fault detection and ...
Optimal demand side management for the sparse scheduling of smart charge of EVs.
(IEEE, 2020)
In this article, we provide a proof of concept realization of a demand response scheme modelling an EV-aggregator offering smart charging 1 coordination services to several Electric Vehicles (EV). The aggregator model ...
Recognition of Faces and Facial Attributes Using Accumulative Local Sparse Representations
(IEEE, 2018)
This paper addresses the problem of automated recognition of faces and facial attributes by proposing a new general approach called Accumulative Local Sparse Representation (ALSR). In the learning stage, we build a general ...
Spatial functional data analysis for regionalizing precipitation seasonality and intensity in a sparsely monitored region: Unveiling the spatio‐temporal dependencies of precipitation in Ecuador
(2018)
The identification of area‐wise homogeneous precipitation regions helps to unveil similar precipitation patterns and amounts, where similar atmospheric processes at diverse temporal scales are likely to occur. However, ...
A fully adaptive multiresolution scheme for shock computations
(Kluwer Academic/plenum Publ, 2001-01-01)
The scheme is based on Ami Harten's ideas (Harten, 1994), the main tools coming from wavelet theory, in the framework of multiresolution analysis for cell averages. But instead of evolving cell averages on the finest uniform ...
