The Prairie Dog Optimization Algorithm (PDOA) is a novel metaheuristic algorithm that takes its inspiration from foraging behavior, burrow building activities and communication alarm of Prairie Dog. PDOA has gained extensive popularity among the research community and is now utilized to tackle a variety of optimization challenges. However, the algo...

The most often used motor in commercial drives is the induction motor. While the induction motor is operating, electrical, thermal, mechanical, magnetic, and environmental stresses can result in defects. Therefore, many researchers who are involved in condition monitoring have been interested in the development of reliable and efficient fault diagn...

This paper introduces a reliable approach based on start-up transient analysis using continuous wavelet transform (CWT) and ridges (local maxima in spectrogram) for early detection of a broken rotor bar fault in an induction motor. The main goal is to track the evolution of the fault frequency components related to rotor bar breakage in the startin...

This paper proposes a new broken rotor bar (BRB) finding technique based on a novel hybrid algorithm, namely the Enhanced Pathfinder Algorithm (EPFA). Compared to existing optimization algorithms, this proposed approach provides more balanced exploration and exploitation. The main task regarding rotor fault detection is to identify sideband frequen...

This paper introduces a reliable approach based on start-up transient analysis using inverse thresholding to spectrogram for early detection of a broken rotor bar fault in an induction motor. The investigation has been done in the time-frequency plane since it is based on the non-stationarity assessment of fault frequencies. Typically, time-frequen...

The squarer or squaring circuit is extensively used in communication systems as a mathematical function with applications of frequency doublers, Finite Impulse Response (FIR) filters, peak amplitude detectors, digital processors and analog multipliers, etc. and especially for square law detection circuits. Vedic multipliers are popular mainly for t...

An efficient and cost effective room heating system using intelligent controller has been designed in this paper. The purpose of the proposed controller is to sense the temperature of a room and actuate the heater to hold the temperature to a fixed desired value in a well-organized way. Firstly conventional Proportional Integral (PI) controller has...
