In the last decades, helicopter-borne electromagnetic (HEM) method became a focus of interest in the fields of mineral exploration, geological mapping, groundwater resource investigation and environmental monitoring. As a standard approach, researchers use 1-D inversion of the acquired HEM data to recover the conductivity/resistivity-depth models. Since the relation between HEM data and model ...

There are possible non-convergence problems at load power critical value while using conventional continuous flow methods. Generally, the step control method is used in calculation to perform small steps convergence value, and this sacrifices speed of although accuracy high. In paper, Levenberg-Marquardt algorithm search for firstly, after that designed fast finding with known which takes into ...

Calibration-free wavelength modulation spectroscopy (WMS) is an efficient technique for trace gas monitoring. It widely used due to its resistance light intensity fluctuations, strong suppression of low-frequency noise, fast response time, and excellent environmental adaptability. The calibration-free WMS often employs the Levenberg–Marquardt algorithm spectral fitting retrieve characteristics....

This paper presents a novel training algorithm for fuzzy inference systems. The algorithm combines the Levenberg-Marquardt algorithm with variable structure systems approach. The combination is performed by expressing the parameter update rule in continuous time and application of sliding mode control method to the gradient based training procedure. The proposed combination therefore exhibits a...

This study presents a new strategy for the identification of material parameters in the case of restricted or redundant data, based on a hybrid approach combining a genetic algorithm and the Levenberg-Marquardt method. The proposed methodology consists essentially in a statistically based topological analysis of the search domain, after this one has been reduced by the analysis of the parameter...

Rivers are dynamic geological agents on the earth which transport weathered materials of continent to sea. Estimation suspended sediment yield (SSY) is essential for management, planning, and designing in any river basin system. SSY critical due its complex nonlinear processes, not captured by conventional regression methods. Rainfall, temperature, water discharge, SSY, rock type, relief, catch...
