This paper addresses the problem of designing robust tracking controls for nonlinear chaotic Chua’s circuits involving plant uncertainties and external disturbances. A hybrid adaptive-robust tracking control scheme which is based upon a combination of the tracking theory, variable structure system (VSS) control algorithm, and adaptive fuzzy control is developed such that all the states and sign...

Real-time traffic flow operation condition of freeway gradually becomes the critical information for the freeway users and managers. In fact, electronic toll collection (ETC) transaction data effectively records operational information of vehicles on freeway, which provides a new method to estimate the travel speed of freeway. First, the paper analyzed the structure of ETC transaction data and ...

Due to the exponential growth of Internet users and traffic, information seekers depend highly on search engines extract relevant information. accessibility a large amount textual, audio, video etc., contents, responsibility has increased. The engine provides concerning their query, based content, link structure, etc. However, it does not guarantee correctness performance is dependent upon rank...

The Ontology for Biomedical Investigations (OBI), written in OWL DL, is being developed by a large consortium seeking to provide a crossdomain, shared framework for representing investigations in the biological and biomedical sciences. In this paper we report our experiences and describe our development process as it pertains to OWL, which includes a number of elements that might inform tool de...

Bulging of a hemicranium and thinning of the temporal bone are encountered in some space-occupying processes, of neoplastic, or parasitic origin, in subdural hygromas, in infantile encephalopathies, etc., and always require supplementary investigations for their discovery and adequate surgical solution. In hygromas, there is a scarcity of neurological signs, and a slightly delayed psychical dev...

Considerable interest has recently been expressed in (static spherically symmetric) blackholes in interaction with various classical matter fields (such as electromagnetic fields, dilaton fields, axion fields, Abelian Higgs fields, non–Abelian gauge fields, etc). A common feature of these investigations that has not previously been remarked upon is that the Hawking temperature of such systems a...

The usefulness of the radiomicrometer in the study of reactions involving a marked color change was indicated in a previous paper (1). It was there shown that the starch-iodine reaction could be investigated in this way. The present paper reports further observations on the reaction, which bear upon the problem of the chemical specificity of some starches and upon the nature of starch-iodide. T...

WITHDRAWN AR IES ACKNOWLEDGEMENTS I would like to thank my two advisors, Professors Shapiro and Counselman, for their assistance in choosing and in carrying out this thesis research. I would also like to thank my wife, but this is impossible, as I am single. ABSTRACT Previous investigations of the evolution of the 3:2 spin-orbit resonance state of the planet Mercury have used simplified mathema...
