Optimal control of a social epidemic model with media coverage
Journal of Biological Dynamics, 2017 A new social epidemic model to depict alcoholism with media coverage is proposed in this paper. Some fundamental properties of the model including existence and positivity as well as boundedness of equilibria are investigated. Stability of all equilibria

A Dynamic Model for Fishery Resource with Reserve Area and Taxation
Journal of Applied Mathematics, 2012 The present paper deals with a dynamic reaction model of a fishery. The dynamics of a fishery resource system in an aquatic environment consists of two zones: a free fishing zone and a reserve zone.

Discrete Dynamics in Nature and Society, 2016 This paper presents a singular prey-predator fishery model, where maturation delay for prey and gestation delay for predator are considered. Fishing efforts are introduced to harvest prey and predator population, which are developed as control ...

Geometry of Optimal Control for Control-Affine Systems
Symmetry, Integrability and Geometry: Methods and Applications, 2013 Motivated by the ubiquity of control-affine systems in optimal control theory, we investigate the geometry of point-affine control systems with metric structures in dimensions two and three.

Optimal control of Cocoa Black pod disease: A multi-pronged approach
Franklin OpenThis study presents a novel approach to controlling cocoa black pod disease, caused by Phytophthora megakarya. Unlike previous methods, we employ a mathematical modeling framework based on Pontryagin’s Maximum Principle to optimize control strategies ...

Nonlinear Analysis, 2013 A dynamical model is proposed and analyzed to discuss the effect of population on a resource biomass by taking into account the crowding effect. It is assumed that the resource biomass, which has commercial importance, is subjected to harvesting.

Frontiers in Quantum Science and TechnologyWe numerically study the optimal control of an atomic Bose-Einstein condensate in an optical lattice. We present two generalizations of the gradient-based algorithm, GRAPE, in the non-linear case and for a two-dimensional lattice.
