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 ...
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 ...
A new approach for computer-aided detection of coronavirus (COVID-19) from CT and X-ray images using machine learning methods
(Elsevier Ltd, 2021)
The COVID-19 outbreak has been causing a global health crisis since December 2019. Due to this virus declared by the World Health Organization as a pandemic, the health authorities of the countries are constantly trying ...
Forecasting fully vaccinated people against COVID-19 and examining future vaccination rate for herd immunity in the US, Asia, Europe, Africa, South America, and the World
(Elsevier Ltd, 2021)
Coronavirus disease 2019 (COVID-2019) has spread rapidly all over the world and it is known that the most effective way to eliminate the disease is vaccination. Although the traditional vaccine development process is quite ...
A mathematical model for through-air drying process of yarn bobbins
(Taylor and Francis Ltd., 2021)
In this study, a mathematical model has been developed to simulate the through-air drying process of yarn bobbins. For this purpose, experimental data was obtained in a prototype experimental set up by passing pressurized ...
The effect of collector parameters on nanofiber yarns produced by electro yarn spinning machine with conical collector
(Taylor and Francis Ltd., 2021)
In this work, electrospun yarns were produced by a nanofiber yarn spinning machine with a conical collector. In the first part, two different polymers (PAN and PVDF-HFP) were used in nanofiber yarn spinning with two different ...
Estimation of power output and thermodynamic analysis of standard and finned photovoltaic panels
(Bellwether Publishing, Ltd., 2021)
This study deals with the estimation of power output and also thermodynamic analysis of two different photovoltaic panels. One of the panels is a standard photovoltaic module without fins (SPV), and the other one is a ...
Analysis of polyacrylonitrile nanofiber yarn formation in electrospinning by using a conical collector and two oppositely charged nozzles
(Taylor and Francis Ltd., 2021)
Nanofiber production by electrospinning has become a common production method as it is an easy and flexible system producing nanofibrous webs. However, direct spinning of nanofibers into a yarn would lead to conversion of ...
