Função Penalidade Baseada na Função Onda Triangular para Tratar Variáveis Discretas do Problema de FPOR
(Sociedade Brasileira de Matemática Aplicada e Computacional, 2016-08-01)
ABSTRACT The Optimal Power Flow problem (OPF) is an important problem of electrical engineering investigated since the 60s. The aim of the OPF problem is to determine theoperation point of a electricity transmission system ...
Discharge Coefficient Analysis for Triangular Sharp-Crested Weirs Using Low-Speed Photographic Technique
(ASCE, 2014)
Abstract
Triangular weirs are commonly used to measure discharge in open channel flow, representing an inexpensive, reliable methodology to monitor water allocation. In this work, a low-speed photographic technique was ...

RESUMEN
En el presente trabajo de investigación se evaluaron los coeficientes de gasto en vertederos de sección triangular de pared delgada, con diferentes ángulos, caudales y pendientes, comparándolas con fórmulas ...
Triangular/trapezoidal current mode for high step ratio modular multilevel dc-dc converter
(2022)
Recent developments in dc powered technologies have increased interest in highly efficient dc-dc converters, especially at high voltage and high-step voltage ratios. Modular multilevel converters (MMCs) are an attractive ...
Modeling the Pathophysiology of Phonotraumatic Vocal Hyperfunction With a Triangular Glottal Model of the Vocal Folds
(2017)
Purpose: Our goal was to test prevailing assumptions about the underlying biomechanical and aeroacoustic mechanisms associated with phonotraumatic lesions of the vocal folds using a numerical lumped-element model of voice ...
