Regularized long wave equations and diffusion equation using Tantawy least square method

open access: yesBoundary Value Problems
This paper presents a new semi-analytical method, the Tantawy Least Squares Method (TLSM), to solve fractional-order regularised long wave (RLW) equation, diffusion equations, and Rosenau-Hyman (RH) equation.

Improved Early-Stage Maize Row Detection Using Unmanned Aerial Vehicle Imagery

open access: yesISPRS International Journal of Geo-Information
Monitoring row centerlines during early growth stages is essential for effective production management. However, detection becomes more challenging due to weed interference and crop row intersection in images.

NONLINEAR FILTERING OF RANDOM SEQUENCES WITH EXTENDED LEAST-SQUARE METHOD 1

open access: yesInformatika, 2018
For nonlinear random sequences filtering the extended least-square method is proposed. The received suboptimal filter equations include linearization for nonlinear measurement function only.

A Study on Optimal Strategy in Relative Radiometric Calibration for Optical Sensors

open access: yesSensors, 2017
Based on the analysis of three main factors involved in the relative radiometric calibration for optical sensors, namely: the number of radiance level; the number of measurements at each level; and the radiance level grouping method, an optimal strategy ...

Comparison between Linear Regression and Robust Regression Models by Using Error Criteria and Information Criteria Applied to Human Sample

open access: yesZanco Journal of Humanity Sciences
Hypertension is a common and serious disease, and for this reason, a sample of patients was chosen from Azadi Teaching Hospital in Duhok. In this study a comparison was made between Ordinary Least Squares (OLS) with two robust methods Least Trimmed ...

A modification of He’s variational approach using the least square method to nonlinear oscillators

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2019
In this paper, we apply the global error minimization method to nonlinear oscillators with fractional terms for determining the first- and second-order approximate frequencies and solutions.

LINEAR FILTRATION OF RANDOM SEQUENCES USING A LEAST SQUARE METHOD WITH REGULARIZATION

open access: yesInformatika, 2017
At high problem dimension the Kalman filter becomes difficult to realize in real time due to the high computational costs. Alternatively, a technique of filter synthesis on the basis of the extended least square method with extended square discrepancy is
