Time-Frequency Analysis of Systems with Changing Dynamic Properties [PDF]

open access: yes, 2006
The Wigner-Ville Distribution, and related refinements, represent a class of advanced time-frequency analysis tools that are distinguished from Fourier and wavelet methods by an increase in resolution in the time frequency plane. Time-frequency analysis

Adaptive Under Frequency Load Shedding Scheme Using Genetic Algorithm Based Artificial Neural Network [PDF]

open access: yesJournal of Electrical and Electronics Engineering, 2019
This paper presents two schemes of UFLS to keep the system frequency within safe limits. GA-based scheme is introduced as an offline method to get the proper amount of shed load achieving the minimum and steady state frequency within permissible limits ...

Frequency dependence of CA3 spike phase response arising from h-current properties [PDF]

open access: yes, 2013
The phase of firing of hippocampal neurons during theta oscillations encodes spatial information. Moreover, the spike phase response to synaptic inputs in individual cells depends on the expression of the hyperpolarization-activated mixed cation current (

FREQUENCY RESPONSE IN REACTING SYSTEMS

open access: yesJOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 1971
For a packed bed of spherical catalyst pellets, where the intraparticle diffusion resistance is negligible at steady-state operation, frequency transfer function for concentration perturbation of reactant for n-th order reaction kinetics is derived in view of the effects of longitudinal dispersion in moving phase, resistance to diffusion in film on ...

Inertia emulation control of VSC-HVDC transmission system [PDF]

open access: yes, 2011
The increasing penetration of power electronics interfaced renewable generation (e.g. offshore wind) has been leading to a reduction in conventional synchronous-machine based generation.

Natural Scene Derived Camera Edge Spatial Frequency Response for Autonomous Vision Systems [PDF]

open access: yes, 2021
The edge Spatial Frequency Response (eSFR) is an established measure for camera system quality performance, traditionally measured under laboratory conditions. With the increasing use of Deep Neural Networks (DNNs) in autonomous vision systems, the input

Numerical Simulation Investigations of the Dynamic Control Process and Frequency Response Characteristics in an Adaptive Optics System [PDF]

open access: yes, 2002
The dynamic control process in an adaptive optics (AO) system is the third important factor to affect the performances of the AO system. A numerical simulation of the dynamic control process in an AO system is carried out for the first time to complete a

Capacitor virtual inertia control and equivalent inertia analysis for a grid-forming wind generation system

open access: yesFrontiers in Energy Research
A grid-forming wind generation system exhibits exceptional grid frequency support abilities. The DC capacitor of the grid-forming wind generation system, which is characterized by rapid response and high sensitivity to minor disturbances, can provide ...

The phase response of primary auditory afferents in a songbird (Sturnus vulgaris L.) [PDF]

open access: yes, 1988
The effects of stimulus frequency and intensity on phase-locking characteristics of cochlear ganglion cells were studied in the starling. All cells showed phase-locking to tone stimuli within their response area. Phase-locking at CF is found on average 9

The frequency response of networks as open systems

open access: yesNature Communications
Abstract Many biological, technological, and social systems can be effectively described as networks of interacting subsystems. Typically, these networks are not isolated objects, but interact with their environment through both signals and information that are received by specific nodes with an input function or ...
