Backward problem for a nonlinear fractional bi-parabolic equation with Gaussian white noise

Tu Tran Quoc, Thanh-Trung Le, Phong Luu Hong

In this paper, we investigate an approach for regularizing the inverse problem associated with the nonlinear bi-parabolic equation involving the fractional Laplacian. Moreover, we consider the source function satisfying locally Lipschitz condition and the input data are perturbed by Gaussian white noise. …

Automated Interactance Near-Infrared Spectral Acquisition System for Mandarin Quality Assessment

Van-Linh Lam, Dinh-Tri Nguyen, Thanh-Trung Le, Hoang-Tien Nguyen et autres

Intelligent fruit grading systems require automated sensing solutions capable of rapid and reliable non-destructive internal quality assessment. While near-infrared spectroscopy has been widely used for soluble solids content (SSC) prediction, most existing studies rely on manually acquired spectra, limiting scalability in smart …

A BACKWARD PROBLEM FOR THE NONLINEAR FRACTIONAL HELMHOLTZ EQUATION WITH GAUSSIAN WHITE NOISE ON THE MEASUREMENT

Phong Luu Hong, Quan Pham Hoang, Thanh-Trung Le

We consider a backward problem for the nonlinear fractional Helmholtz equation with Gaussian white noise, a problem that is severely ill-posed in Hadamard’s sense. We propose the Fourier truncation method to regularize the problem. With different assumptions on the exact solution, the …

Applying DDPG Algorithm to Swing-Up and Balance Control for a Double Inverted Pendulum on a Cart

T.T. Ho, Thanh-Sang Tat, Hoang-Anh Ngo, Truong-Son Nguyen et autres

In this study, we apply the Deep Deterministic Policy Gradient (DDPG) algorithm in reinforcement learning to control a double inverted pendulum on a cart (DIPC)- a high order single input-multi output (SIMO) system . The simulation results demonstrate DDPG's stability and effectiveness …
