A novel third order integrator using polynomial–exponential–trigonometric basis functions for solving the Omicron virus model: South Africa as a case study

Results in Control and Optimization
This study introduces and analyzes a third-order integrator method that combines polynomial–exponential terms with specific trigonometric basis functions, referred to as the Novel Third-Order Integrator (NTOI) method. The proposed method was assessed for

Symplectic Integrators for Systems of Rigid Bodies

, 1996
Recent work reported in the literature suggest that for the long-term integration of Hamiltonian dynamical systems one should use methods that preserve the symplectic structure of the flow.

Solving initial value problem by different numerical methods [PDF]

Our aim was to study what kind of bases can be provided to understand the basic terms of differential equation through teaching mathematical material in secondary school and to what extent this basis has to be expanded so that we can help the ...

Optimization Of Automotive Valve Train Components With Implict Filtering

, 1998
. In this paper we show how the implicit filtering algorithm can be parallelized and applied to problems in parameter identification and optimization in automotive valve train design. We extend our previous work by using a more refined model of the valve

Failure-informed PINNs for a multi-strain SVEIR epidemic model

Discover Applied Sciences
Tightly coupled multi-compartment epidemic models tend to expose a weakness of standard Physics-Informed Neural Networks (PINNs). When collocation points are placed uniformly, the network spends much of its capacity on smooth regions while leaving the ...
