Compressive-Sensing-Based Reflectometer for Sparse-Fault Detection in Elevator Belts
(Institute of Electrical and Electronics Engineers (IEEE), 2020-04)
This article presents a design approach to the early detection of elevator-belt failures. The proposed system is based on the time-domain reflectometer (TDR) techniques with the objective to detect the presence and location ...

Analyzing and Characterizing Common Mode Chokes for Three Phase Systems
(IEEE, 2024-05)
Common mode chokes (CMCs) are widely employed to reduce common mode emissions of three phase systems. This work presents an advanced technique for analyzing and characterizing CMCs with three or four windings. The central ...

Winding Optimization for Reducing Parasitic Capacitances of Common-Mode Chokes
(IEEE, 2024-05)
Parasitic capacitances typically undermine the filtering performance of common mode chokes at high frequencies. This work demonstrates that these parasitic capacitances can be reduced by using a wise winding strategy that ...

Artificial Intelligence Approach in Aerospace for Error Mitigation
(MDPI, 2024)
Many of the reports created at assembly lines, where all components of an aircraft are installed, frequently indicate that errors threaten safety. The proposed methodology in this study evaluates error prediction and risk ...

A short-term evaluation of foot pronation tendency in healthy recreational runners
(MDPI, 2023-11-12)
Running is a highly physical activity, and it is related to injuries when there is an excessive pronation of the foot. This study evaluates, from a sample group of healthy recreational runners, if the foot tends to pronate ...

Chirped Integrated Bragg Grating Design
(MDPI, 2024-05)
We analyze the two classic methods for chirped Integrated Bragg Gratings (IBGs) in Silicon- on-Insulator technology using the transfer matrix method based on the effective refractive index (neff) technique, which translates ...

Predictive Stator Current Control of a Five-Phase Motor Using a Hybrid Control Set
(Institute of Electrical and Electronics Engineers, 2023-04)
Finite state model predictive control (FSMPC) of multiphase drives can use an extra number of inverter configurations compared with the three-phase case. This, however, requires more computing power for the optimization ...

Time-interleaving design of error-feedback sigma-delta modulators with infinite impulse response noise transfer function
(John Wiley and Sons Inc, 2021)
Transceivers built to modern communication standards tend to be as digital as possible, including the radio-frequency stages. This forces the digital-to-analogue converters (DACs) in the transmitter section to have a large ...

Development of an Emergency Radio Beacon for Small Unmanned Aerial Vehicles
(Institute of Electrical and Electronics Engineers Inc., 2018-05)
Emergency locator transmitters (ELTs) used to locate manned aircrafts are not well suited to find and recover small crashed unmanned aerial vehicles (UAVs). ELTs utilize an international satellite system for search and ...
