Photokinetics of Photothermal Reactions by Mounir Maafi

“…The validity of the model equation was established against simulated data obtained by a fourth-order Runge–Kutta method. It was then used to describe and quantify several situations of photothermal reactions, such as the effects of initial concentration, spectator molecules, and incident radiation intensity, and the impact of the latter on the photonic yield. …”

Mixed Convection Squeezing Flow of Nanofluids in a Rotating Channel with Thermal Radiation by Wankui Bu, Hui Xu, Ilyas Khan, Sheikh Irfan Ullah Khan, Anwar Zeb

“…Then, the explanation was obtained numerically by the Runge–Kutta–Fehlberg (RKF) method. The emerging parameters such as quotient of the electric magnetic field to viscous forces (M), Prandtl number (Pr), and Reynolds number (Re), along with physical parameters such as the Nusselt number and skin friction coefficient, will be integrated graphically. …”

A Mathematical Model of Tumor-Immune and Host Cells Interactions with Chemotherapy and Optimal Control by Tarekegn Dinku, Boka Kumsa, Jyotirmoy Rana, Aiyappan Srinivasan

“…The optimal system is solved using the forward-backward sweep method with fourth-order Runge–Kutta approximation. Reduction in tumor cell growth has been observed due to the increase in recruitment of immune cells activated by tumor cell antigenicity and the rate of conversion of resting immune cells into active immune cells. …”

Swarming Computational Procedures for the Coronavirus-Based Mathematical SEIR-NDC Model by Suthep Suantai, Zulqurnain Sabir, Muhammad Asif Zahoor Raja, Watcharaporn Cholamjiak

“…The correctness of the stochastic computing scheme performances is verified by using the comparison of the obtained performances of the mathematical SEIR-NDC system and the reference Runge–Kutta scheme. Furthermore, the graphical illustrations of the performance indices, absolute error, and convergence curves are derived to validate the robustness of the proposed ANN-PSOSQP approach for the mathematical SEIR-NDC system.…”
