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....

A new, to my knowledge, procedure for retrieving the wave aberration from the point-spread function is presented. It uses the Levenberg-Marquardt optimization algorithm in a mutiresolution pyramidal scheme. The method, tested with simulated large aberrations without initial estimates, accelerates convergence and avoids stagnation in local minima.

This paper presents an improved calibration method of a rotating two-dimensional light detection and ranging (R2D-LIDAR) system, which can obtain the 3D scanning map of the surroundings. The proposed R2D-LIDAR system, composed of a 2D LIDAR and a rotating unit, is pervasively used in the field of robotics owing to its low cost and dense scanning data. Nevertheless, the R2D-LIDAR system must be ...

In order to effectively implement a good model based control strategy, the combination of different linear models working at various operating regions are mostly utilised since a single model that can operate in that fashion is always a difficult task to develop. This work presents the use of soft computing approaches such as evolutional algorithm called simulated annealing (SA), a genetic algo...

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...

This research presents a distributed and formula-based bilateration algorithm that can be used to provide initial set of locations. In this scheme each node uses distance estimates to anchors to solve a set of circle-circle intersection (CCI) problems, solved through a purely geometric formulation. The resulting CCIs are processed to pick those that cluster together and then take the average to...
