New results for time reversed symplectic dynamic systems and quadratic functionals

Electronic Journal of Qualitative Theory of Differential Equations, 2012
In this paper, we examine time scale symplectic (or Hamiltonian) systems and the associated quadratic functionals which contain a forward shift in the time variable.

Geometric Modeling for Control of Thermodynamic Systems

Entropy, 2023
This paper discusses the way that energy and entropy can be regarded as storage functions with respect to supply rates corresponding to the power and thermal ports of the thermodynamic system. Then, this research demonstrates how the factorization of the
