Frequency resolved spectroscopy of Cyg X-1: fast variability of the reflected emission in the soft state [PDF]
, 2000 Using the RXTE/PCA data we study the fast variability of the reflected emission in the soft spectral state of Cyg X-1 by means of Fourier frequency resolved spectroscopy. We find that the rms amplitude of variations of the reflected emission has the same

Cyberattacks on Primary Frequency Response Mechanisms in Power Grids
Computer, 2018 Primary frequency response (PFR) is an important mechanism for making power grids resilient to faults that could lead to outages. We present the first study of cyberattacks that could cause power outages by infiltrating operational technology networks in generation control systems to inhibit the PFR.

Energy Reports, 2022 In this paper, we study the optimal configuration problem of battery energy storage (BES) for multi-energy microgrid (MEMG) in two typical modes, which considers demand response in grid-connected mode and primary frequency regulation in islanding mode ...

Optimizing DER Participation in Inertial and Primary-Frequency Response
2019 IEEE Power & Energy Society General Meeting (PESGM), 2018 This paper develops an approach to enable the optimal participation of distributed energy resources (DERs) in inertial- and primary-frequency response alongside conventional synchronous generators. Leveraging a reduced-order model description of frequency dynamics, DERs’ synthetic inertias and droop coefficients are designed to meet time-domain ...

Excitation of multiple 2-mode parametric resonances by a single driven mode
, 2017 We demonstrate autoparametric excitation of two distinct sub-harmonic mechanical modes by the same driven mechanical mode corresponding to different drive frequencies within its resonance dispersion band. This experimental observation is used to motivate

Diversity of intrinsic frequency encoding patterns in rat cortical neurons : mechanisms and possible functions [PDF]
, 2010 Extracellular recordings of single neurons in primary and secondary somatosensory cortices of monkeys in vivo have shown that their firing rate can increase, decrease, or remain constant in different cells, as the external stimulus frequency increases ...

Analytical Approach for Novel Temporary Frequency Support Control of VSC HVDC
IEEE AccessThe grid support function by DC devices such as static synchronous compensator (STATCOM) or high-voltage direct current (HVDC) systems is becoming more important owing to renewable energy integration.

Frequency Analysis of Atrial Fibrillation From the Surface Electrocardiogram [PDF]
, 2004 Atrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice. Neither the natural history of AF nor its response to therapy are sufficiently predictable by clinical and echocardiographic parameters.

Combining frequency and time domain approaches to systems with multiple spike train input and output [PDF]
, 2009 A frequency domain approach and a time domain approach have been combined in an investigation of the behaviour of the primary and secondary endings of an isolated muscle spindle in response to the activity of two static fusimotor axons when the parent ...
