The Investigation of Rayleigh Backscattered Signal Statistics in a phi-OTDR System Incorporating Optical Pre-Amplifier
(IEEE, 345 E 47TH ST, NEW YORK, NY 10017 USA, 2020)
We theoretically model and experimentally demonstrate the photon statistics of Rayleigh backscattered signal in a phi-OTDR based distributed fiber optical sensor in the presence of amplified spontaneous emission noise ...
Improving performance and stability in quantum dot-sensitized solar cell through single layer graphene/Cu2S nanocomposite counter electrode
(PERGAMON-ELSEVIER SCIENCE LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2020)
In this work, we presented an effective nanocomposite to modify the Cu2S film by employing single layer graphene (SLG) frameworks via chemical vapor deposition, and utilized this nanocomposite as counter electrode (CE) ...
Machine Learning Assisted Particle Size and Type Classification Using Wavelength-Dependent Scattering Patterns
(Wroclaw University of Science and Technology (WUST), 2021)
The presence of microplastics in oceans and water supplies have increased to critical levels within the last
decade [1]. In addition to the huge mass of plastics in the seas, additional contribution to water pollution ...
Microgrid environmental impact
(Institute of Electrical and Electronics Engineers Inc., 2020)
Power plants have bad impacts on the environment. One of these impacts is Carbon Dioxide (CO2) emission resulted from power plants that depend on fossil fuel, oil and natural gas. Renewable energy is considered as an ...
PCB component recognition with semi-supervised image clustering [Yari-gözetimli görüntü kümeleme ile baskili devre karti bileşeni tanima]
(Institute of Electrical and Electronics Engineers Inc., 2021)
Classification of surface mounted devices plays an important role on automated inspection systems of printed component board production. Limited number of publicly available datasets which the components are labeled and ...
Investigation of the Effects of Multi-Layer Winding Structures in Two Pole Synchronous Reluctance Machines
(Institute of Electrical and Electronics Engineers Inc., 2021)
In this paper, a comparative study is performed between single, various double, and triple-layer winding structures to investigate the effects of the winding MMF harmonics and end winding length on the two-pole synchronous ...
Sensorless Position and Speed Control of IPMSM with Sliding Mode Observer and Voltage Signal Injection
(Institute of Electrical and Electronics Engineers Inc., 2021)
A sensorless control approach based on a sliding mode observer for predicting the rotor position and speed is studied in this work. For predicting the motor speed and position, the sliding mode observer followed by a phase ...
Effects of curved-beam heights to harvested energy in a blanaced comb-drive configuration
(Institute of Electrical and Electronics Engineers Inc., 2021)
Energy harvesting devices have been gaining increasing interests, especially in the areas of internet of things (IoTs) and sensor networks. Due to the broadband and random nature of typical vibration energy sources available ...
Data-driven discovery and DFT modeling of Fe4H on the atomistic level
(ELSEVIER, 2024)
Since their discovery, iron and hydrogen have been two of the most interesting elements in scientific research, with a variety of
known and postulated compounds and applications. Of special interest in materials engineering ...
Estimation of cohesion for intact rock materials using regression and soft computing analyses
(Institute of Physics, 2024)
Shear strength parameters such as cohesion (c) and internal friction angle (.) are among the most critical rock properties used in the geotechnical design of most engineering projects. However, the determination of these ...
