Investigation of the effect of roughness value on the wettability behavior under electric field in XLPE materials used in medium and high voltage applications
(Springer Science and Business Media Deutschland GmbH, 2021)
XLPE material, which is widely used as a polymeric insulator in medium and high voltage applications, plays an active and important role in electricity transmission and distribution. The aging of XLPE materials due to ...
A Novel Voice Activity Detection for Multi-Channel Noise Reduction
(Ieee-Inst Electrical Electronics Engineers Inc, 2021)
In this study, a voice activity detection technique is designed using features such as short-term energy, periodicity and spectral flatness. The desired results are obtained by using these three features, even at low signal ...
Speech enhancement using adaptive thresholding based on gamma distribution of Teager energy operated intrinsic mode functions
(Turkiye Klinikleri, 2019)
This paper introduces a new speech enhancement algorithm based on the adaptive threshold of intrinsic mode functions (IMFs) of noisy signal frames extracted by empirical mode decomposition. Adaptive threshold values are ...
Kinetic modelling and determination of octylphenol ethoxylate (OPE) and bisphenol A (BPA) (used as plastic additives) inhibition constants for nitrogen conversion
(Global Network Environmental Science & Technology, 2021)
Conversion of ammonia to nitrate is sensitive to a number of inhibitors. There is limited information on the nitrification inhibition coefficient and kinetic model in the current literature. Octyl Phenol Ethoxylate (OPE) ...
DTMOS based low-voltage low-power all-pass filter
(Springer, 2021)
In this paper, a voltage mode all-pass filter design employing floating current sources (FCS) is proposed. The presented all-pass filter circuit contains two floating current sources, one grounded resistor and one floating ...
Characterization of CdS films and CdS/Si heterojunctions prepared by ultrasonic spray pyrolysis and their response to light
(Elsevier B.V., 2020)
In this work CdS thin films were deposited onto glass and p-Si substrates by ultrasonically spraying of precursor solutions prepared in molarity ranging from 0.025 M, to 0.1 M. Structural investigations revealed that all ...
Determination of current transport characteristics in Au-Cu/CuO/n-Si Schottky diodes
