Sufficient criteria are necessary for monotone control volume methods

Border Disease Control Checkpoints: Are They Sufficient for Disease Control? The Present Situation in Thailand

Sufficient and necessary causation are dual

Causation has been the issue of philosophic debate since Hippocrates. Recent work defines actual causation in terms of Pearl/Halpern’s causality framework, formalizing necessary causes (IJCAI’15). This has inspired causality notions in the security domain (CSF’15), which, perhaps surprisingly, formalize sufficient causes instead. We provide an explicit relation between necessary and sufficient ...

Necessary Optimality Conditions for Control of Strongly Monotone Variational Inequalities

In this paper we derive necessary optimality conditions involving Mordukhovich coderivatives for optimal control problems of strongly monotone variational inequalities.

Necessary and Sufficient Conditions for H-∞ Static Output-Feedback Control

Necessary and sufficient conditions are presented for static output-feedback control of linear time-invariant systems using the H∞ approach. Simplified conditions are derived which only require the solution of two coupled matrix design equations. It is shown that the static output-feedback H∞ solution does not generally yield a welldefined saddle point for the zero-sum differential game; condit...

Necessary and sufficient conditions for parameter convergence in adaptive control

-Using Generalized Harmonic Analysis, a complete description of parameter convergence in Model Reference Adaptive Control (MRAC) is given in terms of the spectrum of the exogenous reference input signal. Roughly speaking, if the reference signal "contains enough frequencies" then the parameter vector converges to its correct value. If not, it converges to an easily characterizable subspace in p...
