The Jiles-Atherton model is key to researching the hysteresis loop. focus of scholars across various countries has always been parameter identification model. This paper on Levy whale optimization algorithm (LWOA), based (WOA), proposes overcome disadvantage that WOA tends involve local optimum. recommended uses flight strategy instead encircling prey policy since former improves global search....

The construction of low-cost nanogrids could help speed up the electrification rate in remote communities sub-Saharan Africa. One challenges nanogrid design for these is uncertainty future load demand profiles impacting cabling topology. We propose two new wiring approaches radial direct current power distribution systems. first one a modified minimum spanning tree (MST) algorithm and second an...

Multicast device-to-device (D2D) communication technology is considered as one of the new technologies in fifth generation (5G) networks that directly addresses need for content sharing among internet users. In fact, when direct available between devices, spectral efficiency improved by reusing licensed cellular spectrum. The current studies show D2D increases network capacity and reduces laten...

An effective hybrid cuckoo search algorithm (CS) with improved shuffled frog-leaping algorithm (ISFLA) is put forward for solving 0-1 knapsack problem. First of all, with the framework of SFLA, an improved frog-leap operator is designed with the effect of the global optimal information on the frog leaping and information exchange between frog individuals combined with genetic mutation with a sm...

this paper presents a new modified shuffled frog leaping algorithm (msfla) applied to design simultaneous coordinated tuning of damping controllers to damp the power system low frequency oscillations. for this, a new frog leaping rule is proposed to improve the local exploration and performance of the original sfla and the genetic mutation operator is employed for new frog generation instead of...

Abstract Evolutionary algorithms (EAs) are proficient in solving the controlled, nonlinear multimodal, non-convex problems that limit use of deterministic approaches. The competencies EA have been applied various environmental and water resources problems. In this study, storm management model (SWMM) was set up to authenticate capability for simulating catchment response upper Damodar River bas...

The fault diagnosis of rolling element bearing is great significance to avoid serious accidents and huge economic losses. However, the characteristics nonlinear, non-stationary vibration signals make feature extraction signal become a challenging work. This paper proposes an improved variational mode decomposition (IVMD) algorithm for bearing, which has advantages extracting optimal from decomp...

This study aimed to determine the integrated freshness index (IFI) of eggs using Vis-NIR spectroscopy and optimized support vector regression, which gave first insight into quality from biochemical essence changes. In this work, transmission spectra brown-shell pink-shell egg samples were analyzed between 500 nm 900 nm. Standard normal variables (SNV) used normalize spectral data, Shuffled Frog...

Congestion pricing strategy has been recognized as an effective countermeasure in the practical field of urban traffic congestion mitigation. In this paper, a bi-level programming model considering carbon dioxide emission is proposed to mitigate traffic congestion and reduce carbon dioxide emissions. The objective function of the upper level model is to minimize the sum of travel costs and the ...
