ROBUST NONLINEAR SYNCHRONOUS GENERATOR EXCITATION SYSTEM: INTEGRAL ADAPTATION
Advanced Engineering Research, 2014 The application of a new system - cybernetic approach to the power system synchronous generator control with r egard to their nonlinearity, multidimensionality, and multicoupling, is shown.

On the Contraction of Excitable Systems
CoRRWe study the contraction of Hodgkin-Huxley model and its role in the reliability of spike timings. Without input, the model is contractive in the region of physiological interest. With impulsive synaptic inputs, contraction is retained provided that the input events are sparse enough. Contraction is lost when the input firing rate is too high.

Power Compatibility of Induction Motors in Industrial Grids Containing Synchronous Generators
EnergiesStarting an induction motor causes voltage sag in the industrial grid that may disturb the operation of grid equipment. Direct-on-line starting is the simplest and most cost-effective method for starting induction motors, but also the most problematic ...

Excited States of the Helium-Antihydrogen System [PDF]
Physical Review Letters, 2007 Potential energy curves for excited leptonic states of the helium-antihydrogen system are calculated within Ritz' variational approach. An explicitly correlated ansatz for the leptonic wave function is employed describing accurately the motion of the leptons (two electrons and positron) in the field of the helium nucleus and of the antiproton with ...

Control Systems with Almost Periodic Excitations [PDF]
SIAM Journal on Control and Optimization, 2009 For control systems described by ordinary differential equations subject to almost periodic excitations the controllability properties depend on the specific excitation. Here these properties and, in particular, control sets and chain control sets are discussed for all excitations in the closure of all time shifts of a given almost periodic function ...

On the Stabilization of Persistently Excited Linear Systems [PDF]
SIAM Journal on Control and Optimization, 2010 We consider control systems of the type $\dot x = A x +α(t)bu$, where $u\in\R$, $(A,b)$ is a controllable pair and $α$ is an unknown time-varying signal with values in $[0,1]$ satisfying a persistent excitation condition i.e., $\int_t^{t+T}\al(s)ds\geq μ$ for every $t\geq 0$, with ...

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 ...
