Analysis of double-parallel amplified recirculating optical-delay lines [PDF]

, 1994
A novel method of analysis of double-parallel amplified recirculating optical-delay lines (DPAROD) is presented. The location of the maxima and the minima of the transfer function for this configuration is calculated and experimentally demonstrated.

Technical note: Estimating unbiased transfer-function performances in spatially structured environments

, 2015
. Conventional cross validation schemes for assessing transfer-function performance assume that observations are independent. In spatially structured environments this assumption is violated, resulting in over-optimistic estimates of transfer-function ...

Ivabradine increases the high frequency gain ratio in the vagal heart rate transfer function via an interaction with muscarinic potassium channels

Physiological Reports, 2021
Muscarinic potassium channels (IK,ACh) are thought to contribute to the high frequency (HF) dynamic heart rate (HR) response to vagal nerve stimulation (VNS) because they act faster than the pathway mediated by hyperpolarization‐activated cyclic ...

Formulation and experimental validation of a frequency transfer function of a rotor system with both an open crack and anisotropic support stiffness

Nihon Kikai Gakkai ronbunshu, 2018
This paper proposes a transfer function of rotating shaft system considering both an open crack and anisotropy in bearing support stiffness, which are both fundamental characteristics often observed in the rotating machinery.

Limits on the amplification of evanescent waves of left-handed materials

, 2005
We investigate the transfer function of the discretized perfect lens in finite-difference time-domain (FDTD) and transfer matrix (TMM) simulations; the latter allow to eliminate the problems associated with the explicit time dependence in FDTD ...
