some scientists are interesting to study in area of harvested ecological modelling. the harvested population dynamics is more realistic than other ecological models. in the present paper, some of the lotka-volterra predator-prey models have been considered. in the said models, existing species are harvested by constant or variable growth rates. the behavior of their solutions has been analyzed ...

In this paper, a prey-predator system that called human immunodeficiency virus (HIV) models is considered, and sliding mode control (SMC) is used to stabilize this system. The basic model is a 3-dimensional nonlinear ODEs that describes the interaction of the HIV with target cell, cell and macrophage. Lyapunove function is constructed to establish the global asymptotic stability of the uninfect...

We will discuss localized measures related to the concepts of dimension, Lyapunove exponents (entropy), and recurrence diagrams. We stress the relevance of localized events and coincidences in physiological time series that often are lost when statistical averaging methods are applied. We suggest event-based statistics as an alternative to spectral or averaged-based statistics. The use of wavel...
