Comments on "increasing the natural frequencies of circular disks using internal channels"
(Academic Press Ltd - Elsevier Science Ltd, 2001-03-08)
An investigation on a novel design of computer disk drive disks that raises their natural frequencies was presented. Natural frequencies were raised by adequately subtracting mass from the structural element under ...
The effect of actuator and sensor placement on the active control of rotor unbalance
(2003-07-01)
This paper investigates both theoretically and experimentally the effect of the location and number of sensors and magnetic bearing actuators on both global and local vibration reduction along a rotor using a feedforward ...
Cross-frequency interaction of the eye-movement related LFP signals in V1 of freely viewing monkeys
(2013)
Recent studies have emphasized the functional role of neuronal activity underlying oscillatory local field potential (LFP) signals during visual processing in natural conditions. While functionally relevant components in ...
On the harmonic response of plates with the shear deformation effect using the elastodynamic solution in the boundary element method
(Elsevier Sci LtdOxfordInglaterra, 2007)
Arbitrary precision frequencies of a free rectangular thin plate
(Elsevier, 2000-02)
A variational method developed by the authors and named whole element
method (WEM) is used to find the arbitrary precision frequencies of a rectangular thin plate (within the Germain}Lagrange theory) having its four borders ...
Modulation of frequency preference in heterogeneous populations of theta-resonant neurons
(Pergamon-Elsevier, 2020)
Neurons from several brain regions resonate in the theta frequency range (4-12 Hz), displaying a higher voltage response to oscillatory currents at a preferred 'resonant' frequency (f(R)). Subthreshold resonance could ...
Instantaneous frequencies in the Kuramoto model
(2020-11-23)
Using the main results of the Kuramoto theory of globally coupled phase oscillators combined with methods from probability and generalized function theory in a geometric analysis, we extend Kuramoto's results and obtain a ...
Dynamic analysis of a new piezoelectric flextensional actuator using the J1-J4 optical interferometric method
(2005-12-01)
Piezoelectric actuators are widely used in positioning systems which demand high resolution such as scanning microscopy, fast mirror scanners, vibration cancellation, cell manipulation, etc. In this work a piezoelectric ...
The effect of actuator and sensor placement on the active control of rotor unbalance
(2003-07-01)
This paper investigates both theoretically and experimentally the effect of the location and number of sensors and magnetic bearing actuators on both global and local vibration reduction along a rotor using a feedforward ...
Análisis del deslizamiento y de la frecuencia natural de las bandas trapezoidales en función del pretensado con diferentes longitudes del tramo libre
(Escuela Superior Politécnica de Chimborazo, 2021-12-12)
The objective of this study was to analyze the slip and the natural frequency of the trapezoidal belts as a function of the prestress with different lengths of the free section through the design and implementation of a ...
