Unified Filtered Operator Analysis of Experimental Chaos in Optically Injected Solid State Laser Systems

We apply the unified filtered operator to real experimental time series data obtained from optically injected solid state laser systems. Unlike classical differentiation, which is highly sensitive to noise and rapid chaotic transitions, the unified operator computes meaningful derivatives only within physically relevant, slow-varying regions.

Fractional Moment Theory for Anomalous Transport: A Unified Framework for Lévy Flights, Fractals, and Complex Dynamical Systems

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We develop a unified mathematical framework extending classical moment theory from discrete integer orders to a continuous spectrum of real orders f>0$$ f>0 $$, providing a systematic statistical characterization of complex systems exhibiting power‐law behavior.

Improvement of Water Allocation Planning and Practical Operation in the Upper East Bank of the Chao Phraya Delta - Activities under the Modernization of Water Management System Project in Thailand -
Agriculture is one of the main industries in Thailand. The Thai Government clearly stated in the Eighth Agricultural Development Plan(MOAC, 1998) that strengthening Thailand's international competitive position through production of high valued and diversified products and effective utilization of natural resources for sustainable agriculture were the ...

Robust Position Control of an Electro‐Hydraulic Actuator via Metaheuristic Optimization of a Fractional‐Order PID Controller

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In this study, a robust position control strategy is presented for a two‐stage electro‐hydraulic actuator system using a fractional‐order proportional–integral–derivative (FOPID) controller tuned by Kirchhoff's law algorithm (KLA). Electro‐hydraulic systems exhibit strong nonlinearities, parameter uncertainties, and external disturbances ...
