A theory of memory retrieval
- PSYCHOL. REV
, 1978
"... A theory of memory retrieval is developed and is shown to apply over a range of experimental paradigms. Access to memory traces is viewed in terms of a resonance metaphor. The probe item evokes the search set on the basis of probe-memory item relatedness, just as a ringing tuning fork evokes sympath ..."

RESONANCE TUNING IN SINGING
, 2007
"... Near its resonances, the vocal tract matches the high acoustic impedance at the vocal folds to the radiation impedance at the mouth. The first two or three frequency bands of high radiated power (formants) determine the vowel produced. By measuring these resonances directly during singing, we previo ..."

previously confirmed a suggestion by Sundberg that, in their high range, sopranos tune the first tract resonance to or slightly above the frequency of the note sung, thereby increasing power and timbral homogeneity. For male voices, the fundamental (f0) would exceed the normal value of the first resonance (R
Extended Frequency Bandwidth and Electrical Resonance Tuning
- in Hybrid Terfenol-D/PMN-PT Transducers in Mechanical Series Configuration
, 2005
"... ABSTRACT: This article addresses the modeling and characterization of hybrid transducers incorporating both ferroelectric and ferromagnetic elements. The complementary electrical and mechanical properties of the two classes of materials can yield transducers with higher performance or enhanced funct ..."

functionality relative to single-element devices. As a template for studying the properties of hybrid architectures, a transducer is considered which consists of a mechanical series arrangement of a PMN-PT stack and a Terfenol-D rod. This configuration exhibits a double resonant frequency response that can
An Electronically Tunable Resonator for Noise Control
, 2001
"... Many engineering systems create unwanted noise that can be reduced by the careful application of engineering noise controls. When this noise travels down tubes and pipes, a tuned resonator can be used to muffle noise escaping from the tube. The classical examples are automobile exhaust and ventilati ..."

within the tuned resonator frequency range, the device is effective. However, if the frequency of the unwanted sound changes to a frequency that does not match the tuned resonator frequency, the device is no longer effective. Conventional resonators have fixed tuning and cannot effectively muffle tonal
Frequency Response Range of Semiactive Magnetorheological Tuned Mass Dampers
"... The effective frequency range of a controlled semiactive tuned mass damper equipped with a magnetorheological variable damping device is assessed. The phenomenological model for the magnetorheological damper and a sliding mode controller with a clipped-optimal control algorithm are used to simulate ..."

HIGH-SPEED AND WIDE-TUNING-RANGE LC FREQUENCY DIVIDERS
"... Wide tuning-range frequency dividers based on an LC resonator are proposed for high-speed transceivers. The proposed circuit is fabricated using a two-metal and 0.5-µm-gate CMOS process and realizes the minimum and the maximum frequencies of 7.74 GHz and 8.16 GHz, respectively, with the power consum ..."

Whole body L-Band Resonator with a wide range frequency tuning using piezo actuator
"... Measurements by present in vivo L-band EPR often are enhanced by using whole body resonators, but use of such resonators are connected with several challenging problems. One is the relatively large change in the resonator fre-quency caused by voluntary and involuntary movements of the animal. To ove ..."

to change the resonant frequency by about 15 MHz. With the use of an automatic frequency control (AFC) system, this tuning range is sufficient to keep the resonant frequency constant and to compensate for the effects caused by the movements of the investigated object. A step motor is used as the base
Location-Dependent Frequency Tuning of Vibrating Micromechanical Resonators Via Laser Trimming
"... Abstract—Location-dependent, bidirectional laser trimming of the resonance frequencies of vibrating micromechanical resonators is demonstrated in steps as small as 21 ppm over a range of 20,200 ppm, and with targeting measures that suppress unwanted variations in Q and series motional resistance.

Contrary to a simple and inaccurate cut-off circular collision model that is commonly used, we employ a more accurate collision model to realistically simulate MAC schemes i ..."

in ad hoc networks. We argue that the carrier sensing range is a tunable parameter that can significantly affect the MAC performance in multihop ad hoc networks. An optimal carrier sensing range should balance the trade-off between the amount of spatial frequency reuse and the possibility of packet
