Accurate classification of power load is the premise demand-side response capability evaluation, which great significance for management. Therefore, this study proposes a selection method joint characteristics in time domain and frequency based on whale optimization algorithm. The electrical measurement data six typical equipment are selected to form original identification dataset. Firstly, fe...

In this article, a pitch tracking algorithm [named discrete logarithmic Fourier transformation-pitch detection algorithm (DLFT-PDA)], originally designed for human telephone speech, was modified for killer whale vocalizations. The multiple frequency components of some of these vocalizations demand a spectral (rather than temporal) approach to pitch tracking. The DLFT-PDA algorithm derives relia...

To facilitate cost-effective and elastic computing benefits to the cloud users, energy-efficient secure allocation of virtual machines (VMs) plays a significant role at data centre. The inefficient VM Placement (VMP) sharing common physical among multiple users leads resource wastage, excessive power consumption, increased inter-communication cost security breaches. address aforementioned chall...

This paper introduces a novel methodology for the optimum design of linear tuned mass dampers (TMDs) to improve seismic safety structures through Whale Optimization Algorithm (WOA). The algorithm is aimed reduce maximum horizontal peak displacement structure, and root mean square (RMS) response displacements as well. Furthermore, four additional objective functions, derived from multiple weight...

Reflective Fourier ptychographic microscopy has much potential for industrial surface inspection due to the ability overcome physical limits of numerical aperture optical microscopy. However, time cost misalignment calibration and ptychography (FP) recovery been a big issue applications which require fast output. Here, we introduce estimation method is accelerated through whale optimization alg...
