Accurate and efficient implementation of the time–frequency matched filter
( Institution of Engineering and Technology , 2010 , Article)The discrete time-frequency matched filter should replicate the continuoustime-frequency matched filter, but the methods differ. To avoid aliasing, thediscrete method transforms the real-valued signal to the complex-valued ... -
Accurate Classification of Partial Discharge Phenomena in Power Transformers in the Presence of Noise
(2017 , Master Thesis)The objective of this research is to accurately classify different types of Partial Discharge (PD) phenomenon that occurs in transformers in the presence of noise. A PD is an electrical discharge or spark that bridges a ... -
Accurate fault location algorithm for shunt-compensated double circuit transmission lines using single end data
( Elsevier , 2020 , Article)This paper introduces an accurate fault location algorithm for double-circuit transmission lines compensated by Static Var Compensator (SVC). The proposed algorithm is based on the negative-sequence circuit of the transmission ... -
Accurate fault location element for series compensated double-circuit transmission lines utilizing negative-sequence phasors
( Elsevier , 2021 , Article)Obtaining the accurate fault location in the series compensated double-circuit transmission lines (SCDCTL) is a challenge due to the presence of series compensator, fault resistance, and mutual the coupling between parallel ... -
An accurate finite volume method using fourth order Adams scheme on triangular grids for the Saint-Venant System
(2013 , Conference Paper)In this study, a new finite volume method is developed for shallow water equations on a rotating frame. Most upwind methods, which perform well for gravity waves, lead to large oscillations and/or numerical damping for ... -
Accurate Fundamental Harmonic Modeling of Inductive Power Transfer Battery Chargers
( Institute of Electrical and Electronics Engineers Inc. , 2022 , Article)This article presents a precise fundamental harmonic approximation (FHA) for modeling series-series compensated inductive power transfer (IPT) systems with constant voltage load, e.g., with battery load.

(2013 , Conference Paper)Accurate partial discharge (PD) classification provides significant information to asses power transformers' insulation condition. The work presented in this paper aims to improve classification from acoustic emission ... -
Accurate PpT Data for Methane from (300 to 450) K up to 180 MPa
( American Chemical Society , 2010 , Article)This paper reports PFT data measured with a high-pressure, single-sinker, magnetic-suspension densimeter (MSD) from (300 to 450) K up to 180 MPa. Our MSD technique yields accurate data, with less than 0.05 % relative u ... -
Accurate prediction of dynamic viscosity of polyalpha-olefin boron nitride nanofluids using machine learning
( Elsevier , 2023 , Article)This study focuses on predicting the dynamic viscosity of nanofluids, specifically Polyalpha-Olefin-hexagonal boron nitride (PAO-hBN) using machine learning models. The primary goal of this research is to assess and contrast ... -
Ace2 is an adjacent element of atherosclerosis and covid-19 pathogenesis
( MDPI , 2021 , Article Review)COVID-19 is a highly contagious new infection caused by the single-stranded RNA SarsCoV-2 virus. For the first time, this infection was recorded in December 2019 in the Chinese province of Wuhan. The virus presumably crossed ... -
Acetylcholinesterase inhibitors and risk of bleeding and acute ischemic events in non-hypertensive Alzheimer's patients
( John Wiley and Sons Inc , 2021 , Article)Introduction Acetylcholinesterase inhibitors (AChEIs) are commonly used to treat mild to moderate cases of Alzheimer disease (AD). To the best of our knowledge, there has been no study estimating the risk of bleeding and ... -
