Figure 1.An atomic clock has three basic components: an atomic resonance, an oscillator to probe and lock to the atomic resonance, and a counter that records the number of oscillations and thus displays the time interval since some chosen starting time. ...
with the advent of hypermobility materials (Pfeiffer et al., 1989), many new effects such as NDC, material for nonlinear optics (Tsu and Esaki, 1971), parametric light amplifier (Monsivais et al., 1990; Tsu, 1990), and ultimately a terahertz Bloch oscillator, are experimentally realizable ...
Part 1: Free oscillations Free oscillations of an elasto-plastic oscillator with kinematic hardening are analyzed in this paper. A bilinear hysteretic model is used to represent the... R Pratap,S Mukherjee,FC Moon - 《Journal of Sound & Vibration》 被引量: 74发表: 1994年 Dynamical Friction ...
Any small antenna tuned to a resonance can be described as an oscillator with radiative losses and the effect of the environment on its radiation can be modeled and measured in terms of the antenna radiation resistance, similar to a quantum emitter. We exploit this analogue behavior to develop ...
Brain oscillations have classically been considered as purely dependent on the physical and functional contacts between the neurons involved in the ensemble. Non-neuronal contributions have been largely overlooked until recently, but they are starting to be the subject of comprehensive reviews [152]. Gl...
In some cases, where it is not possible or at all practical to use a contactor or switch, a vacuum tube oscillator has been proposed, by means of which Io the grid of the glow tube or discharge device is raised to proper potential to cause a breakdown, or discharge, of the discharge ...
The oscillator produces an excitation torque supplied to the blade together with the soil cutting torque. The advantage of the vibrating blade is a reduction in the cutting torque of up to 70%. However, to correctly design the oscillator, we need to investigate the link between the maximum ...
Limitations of the commutation frequency produces undesired oscillations around the operation point and effectively increases the settling times. Additional controllers, such as P or PIs in the high frequency steady operation, can be used in order to better handle undesired oscillations and/or reject ...
The voltage rejection making the LED current almost oscillator produces pulses at regular intervals. These insensitive to input voltage variations. But, it leads to pulses set the SR flip-flop in the An9910B which variable frequency operation and the frequency range causes the GATE driver to turn...
