On Boundary Null Controllability of Strongly Degenerate Hyperbolic Systems on Star-Shaped Planar Network

Journal of Optimization, Differential Equations and Their Applications, 2021
In this paper we discuss the problem of boundary exact null controllability for weakly and strongly degenerate linear wave equation defined on star-shaped planar network. The network is represented by a singular measure in a bounded planar domain.

Analysis and control of polling systems [PDF]

, 2005
We present methods for analyzing continuous-time multi-channel queueing systems with Gated, Exhaustive, or Globally-Gated service regimes, and with Cyclic, Hamiltonian or Elevator-type polling mechanisms. We discuss issues of dynamically controlling the server's order of visits to the channels, and derive easily implementable index-type rules that ...

CONTROLLABILITY ANALYSIS OF SISO SYSTEMS

IFAC Proceedings Volumes, 1994
Abstract The objective of this paper is to derive some fundamental results for controllability analysis of scalar systems. The effects of disturbances, delays, constraints and RHP-zeros are quantified. These results are applied to a neutralization process where it is shown that the process must be modified to get acceptable controllability.

A nonlinear control system with a Hilfer derivative and its optimization

, 2019
In this work, we consider a fractional optimal control problem (FOCP) containing a nonlinear control system, described by a differential equation involving a Hilfer derivative, and an integral cost functional.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
