Control of Oscillation Amplitude of Oscillating Motors
Elektronika ir Elektrotechnika, 2010 The problem of increasing of performance parameters and efficiency of oscillating motors with hyperbolical dependence of permeance is analyzed in this paper. For this purpose it is used sharp rise part of dependence of permeance on coordinate of pendulum λ(h) approaching pendulum to the stator at most.

Advanced Materials, EarlyView.Hydration‐induced symmetry breaking transforms layered LiInP2S6${\rm LiInP}_2{\rm S}_6$ from a nonpolar to a chiral‐polar phase, producing a giant enhancement of non‐resonant second‐harmonic generation. The reversible tuning of polar order through molecular intercalation establishes a strategy for dynamically controlling nonlinear optical ...

Controlling Radiative Phonons in the van der Waals Ferroelectric NbOI2
Advanced Materials, EarlyView.Using a simple mirror geometry, this work demonstrates local‐density‐of‐optical‐states control of THz phonon emission in van der Waals ferroelectric NbOI2. By engineering the photonic environment, the phonon Q‐factor, linewidth, peak frequency, and emission intensity are reversibly tuned by over an order of magnitude, revealing radiative phonons as ...

Advanced Materials Interfaces, EarlyView.Supramolecular aggregation governs the interfacial adsorption, diffusion, and fixation of anthraquinone‐based vat dyes in meta‐aramid fibers. By correlating reduction chemistry, aggregate formation, and fiber microstructure, a multiscale mechanism for aggregation‐controlled dyeing is established, providing an effective strategy to suppress surface dye ...

Bursting Behavior in the System of Coupled Oscillators with Delay and its Statistical Analysis
Моделирование и анализ информационных систем, 2015 The statistical analysis of random quantities derived from the dynamics of interaction of a pair of neuron-type oscillators are presented. It is shown that computation of some statistical characteristics of the process allows, with enough precision, to ...

Spurious oscillations in IMPATT oscillators
Electronics Letters, 1975 Incorrect circuit design of cavity-controlled IMPATT oscillators may cause low-frequency instabilities and frequency jumping, which are simply avoidable. A simple technique for identifying the avalanche resonance frequency of packaged IMPATT oscillators is also described.
