The UNCCD has been ratified by over 190 countries. It is the attempt by nations, both rich and poor to control the scourge of desertification. The definition of which is “land degradation in arid, semiarid, and dry subhumid areas resulting from various factors, including climatic variations and human activities. It is now widely accepted that desertification is not the relentless advance of des...

Application to Adaptive Control to Synchronous Machine Excitation

Self-tuning adaptive control technique has the advantage of being able to track the system operating conditions so that satisfactory control action can always be produced. Self-tuning algorithms can be implemented easily. Because the power systems are usually time varying non-linear systems and their parameters vary, adaptive controllers are very suitable for power systems. Characteristics of a...

Addiction to Internet, Modeling and Control

In this paper, we propose a  mathematical model of addiction to Internet. We investigate the effect of educational programs on the control of the addiction. We compute basic reproduction number. By using Chavez-Song theorem, we show the occurrence of backward bifurcation. We prove the global stability of the equilibrium points using geometric stability method and Lyapunov function.
