Development of a Robust Observer for General Form Nonlinear System: Theory, Design and Implementation

The problem of observer design for nonlinear systems has got great attention in the recent literature. The nonlinear observer has been a topic of interest in control theory. In this research, a modified robust sliding-mode observer (SMO) is designed to accurately estimate the state variables of nonlinear systems in the presence of disturbances and model uncertainties. The observer has a simple ...

Changing Trends in General Paresis

King (1958), in deploring the conmmonly held view that venereology is in decline as a specialty, suggests that the proportion of late syphilis may well have increased to-day since treatment has become easier to administer, and less systemuatic therapy is given in the early stages.
