Global regulation of uncertain manipulators using bounded controls
TLDR
This paper considers the position regulation problem for uncertain robot manipulators in the presence of constraints on the available actuator torques, and proposes two new controllers as solutions to this problem. Expand

Detecting the symmetry of attractors
Abstract This paper addresses the issue of how to determine numerically the symmetry of an attractor for dynamical systems. (The symmetries of attractors in phase space are related to patterns in theExpand

Adaptive control of nonholonomic mechanical systems
TLDR
This paper considers the problem of controlling nonholonomic mechanical systems in the presence of incomplete information concerning the system model and state, and presents a class of adaptive controllers as a solution to this problem. Expand

The relation between the ciliary muscle and the trabecular meshwork and its importance for the effect of miotics on aqueous outflow resistance
Despite the successful clinical use of miotics in chronic simple glaucoma, the exact mechanism of their therapeutic action is not known. I t is not clear whether their primary point of attack is onlyExpand

Identification in the presence of symmetry: oscillator networks
TLDR
We investigate the role that structural properties such as symmetry play in the problem of system identification, that is, determining the values of the parameters in the model using measurements of inputs and outputs. Expand

Bifurcations with local gauge symmetries in the Ginzburg-Landau equations
Abstract An interesting class of physical systems are those that exhibit local gauge symmetries: internal invariances that can be implemented independently at any space-time point. Systems in whichExpand

A NOTE ON THE DYNAMICS OF AN SAIQR INFLUENZA MODEL
There is an extensive literature on the modications of classi- cal Susceptible-Infected-Recovered (SIR) models, the bread and butter in the study of disease dynamics, that support the concept ofExpand
