We consider the oscillations of numerical solutions for the nonlinear delay differential equations in the control of erythropoiesis.The exponential θ-method is constructed and some conditions under which the numerical solutions oscillate are presented.Moreover, it is proven that every nonoscillatory numerical solution tends to the equilibriumpoint of the continuous system.Numerical examples are...

TCP Vegas has been introduced in an attempt to improve the performance of TCP Reno and reduce the oscillation e ects. TCP Vegas is, however, criticized for penalizing the users using it in the presence of other users using TCP Reno. In this paper, we model the problem of congestion control as both a single shot game and a repeated game, using a game theoretic approach. We rst show that in the s...

The spatiotemporal dynamics of a phytoplankton-zooplanktonmodelwith an alternative prey and refuge effect is investigatedmathematically and numerically.The stability of the equilibriumpoint and the travelingwave solution of the phytoplankton-zooplankton model are described based on theoretical mathematical work, which provides the basis of the numerical simulation.The numerical analysis shows t...

In this paper, we have proposed a study on controllability and optimal harvestingof a prey predator model and mathematical non linear formation of the equation equilibriumpoint of Routh harvest stability analysis. The problem of determining the optimal harvestpolicy is solved by invoking Pontryagin0s maximum principle dynamic optimization of theharvest policy is studied by taking the combined h...

This thesis presents a hierarchical control algorithm for quadrupedal locomotion. We address three challenges in developing a controller for high-speed running: locomotion stability, control of ground reaction force, and coordination of four limbs. To tackle these challenges, the proposed algorithm employs three strategies. Leg impedance control provides programmable virtual compliance of each ...

A decoupled sliding-mode neural network variable-bound control system (DSMNNVB) is proposed to control rotating stall and surge in jet engine compression systems in presence of disturbance and uncertainty. The control objective is to drive the systemstate to the original equilibriumpoint and it proves that ccepted 7 February 2010 vailable online 11 February 2010 eywords: xial compressors liding...
