What are the early trends we should look for to identify a stock that could multiply in value over the long term?
The aim of this work was to develop an efficient algorithm for evaluation mutual shift of signals obtained during ultrasonic SHM by UGW method. Principle The method used is based on the identification ...
Damage detection in structures and systems is essential for monitoring parameters that can affect their integrity. This paper evaluates the efficiency of four damage indices (DIs) commonly used with ...
Abstract: This article proposes hybrid selective harmonic mitigation (SHM)-pulsewidth modulation (PWM) that is characterized by both features harmonic mitigation and elimination aimed to reduce the ...
Abstract: In this paper, selective harmonic mitigation (SHM) and selective harmonic elimination (SHE) modulation techniques have been combined to produce appropriate pulses for a four-leg three-level ...
