Abstracts of Current Research:
- Light-dark cycles in algae cultivation: The statistical characteristics of light-dark cycles in algal biotechnology reactors are analyzed using methodsof the theory of stochasticprocesses
- Spontaneous waves in perturbed integrable nonlinear evolution equations: Physically meaningful perturbations that are added to integrable nonlinear evolution equations generate spontaneously waves that are different from the solution one is seeking. The coupling between the solution and the spontaneous wave is the source of the loss of integrability of the perturbed equation. The cases of the Burgers and KdV equations has been studied.
- Nonlinear dynamics: The method of normal forms is employed in the analysisof perturbed integrable nonlinear systems. The freedom in the expansion of the
