A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems
International Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.

Finite Element Analysis for Upper Molar Distalization
Romanian Journal of Oral Rehabilitation, 2012 Orthodontic literature indicates that upper molar distalisation is a tipping and extrusion movement, combined with mesio-buccal rotation and buccaly-crown torque, depending on the distalisers used.

Crownwall Failure Analysis through Finite Element Method
Journal of Marine Science and Engineering, 2020 Several failures of recurved concrete crownwalls have been observed in recent years. This work aims to get a better insight within the processes underlying the loading phase of these structures due to non-breaking wave impulsive loading conditions and to

De Rham Complexes for Weak Galerkin Finite Element Spaces [PDF]
arXiv, 2020 Two de Rham complex sequences of the finite element spaces are introduced for weak finite element functions and weak derivatives developed in the weak Galerkin (WG) finite element methods on general polyhedral elements. One of the sequences uses polynomials of equal order for all the finite element spaces involved in the sequence and the other one uses

Finite Element Fatigue Analysis of Unsupported Crane
Polish Maritime Research, 2021 The presented strength and fatigue calculations refer to an unsupported deck crane and its three distinct parts: housing, jib and column. Static loads applied to the structure were due to the crane’s own weight and a maximum working load, corresponding ...
