An Efficient Galerkin BEM to Compute High Acoustic Eigenfrequencies
(ASME-AMER SOC MECHANICAL ENG, 2009)
An efficient numerical method, using integral equations, is developed to calculate precisely the acoustic eigenfrequencies and their associated eigenvectors, located in a given high frequency interval. It is currently known ...
Harmonics Measurement With a Modulated Sliding Discrete Fourier Transform Algorithm
(Institute of Electrical and Electronics Engineers, 2014-04)
Accurate harmonics estimation has become a key issue in power quality assessment. This paper deals with a discrete Fourier transform (DFT)-based measurement technique,which can be easily employed to accurately determine ...
An adversarial model for paraphrase generation
(Universidad Católica San PabloPE, 2020)
Paraphrasing is the action of expressing the idea of a sentence using
different words. Paraphrase generation is an interesting and challenging
task due mainly to three reasons: (1) The nature of the text is discrete, ...
Proposta de uma abordagem para modelagem e simulação de eventos discretos integrada com simulação baseada em agentes : aplicação em uma linha de montagem
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia de Produção - PPGEPCâmpus São Carlos, 2017-12-19)
In this research we propose an approach for the construction of Discrete Event Simulation (DES) models integrated with Agent Based Simulation (ABS) to improve the representation of production systems in a simulation ...
Estructuras localmente conformes Kähler y localmente conformes simplécticas en solvariedades compacta
(2017-03)
En esta tesis estudiamos las estructuras localmente conformes Kähler (LCK) y localmente conformes simplécticas (LCS) invariantes a izquierda en grupos de Lie, o equivalentemente tales estructuras en álgebras de Lie.
Luego ...
H-2 control of discrete-time Markov jump linear systems with uncertain transition probability matrix: improved linear matrix inequality relaxations and multi-simplex modelling
(Inst Engineering Technology-ietHertfordInglaterra, 2013)
Solução do fluxo de potência ótimo reativo com variáveis discretas utilizando um método de pontos interiores e exteriores com estratégia de correção de inércia
(Universidade Estadual Paulista (Unesp), 2017-06-02)
O problema de Fluxo de Potência Ótimo Reativo (FPOR) tem como objetivo otimizar um critério associado a potência reativa do sistema elétrico, levando em conta os limites físicos e técnicos-operacionais do mesmo. O problema ...
Evaluation of the proper coherence representation in random flow generation based methods
(Elsevier Science, 2017-09)
The interest in synthetic methods relies in the fact that reliability of methodologies such as large eddy simulations (LES) or direct numerical simulations strongly depends on how well the developed turbulence is characterized, ...
Continuous random field representation of stochastic moving loads
(2022)
While the problem of random loads moving across a beam has been studied extensively, the existing methods are limited in terms of their applicability. The most common approach uses modal superposition, which requires that ...
