On the tracking of resonance and antiresonance of a piezoelectric resonator
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1991A quantitative analysis of the tracking of the zero-phase resonance frequency, f(r), and antiresonance frequency, f(a), of a piezoelectric resonator reported previously by the author (1990) is presented. Integral and integrodifferential equations for the system angular frequency omega( t) are derived, and numerical calculations are carried out for a ...

The Limitations of “Resonance”
Journal of Ancient Judaism, 2013In 2011, Joshua Berman published a contribution to the ongoing scholarly debate over the sources and dating of Deuteronomy: 'CTH 133 and the Hittite Provenance of Deuteronomy 13.' Berman asserted that a Hittite treaty text from the fifteenth century B. C. E.

Progress in Nuclear Magnetic Resonance Spectroscopy, 2014
Cavity resonators are widely used in electron paramagnetic resonance, very high field magnetic resonance microimaging and also in high field human imaging. The basic principles and designs of different forms of cavity resonators including rectangular, cylindrical, re-entrant, cavity magnetrons, toroidal cavities and dielectric resonators are reviewed ...

Resonances in scattering by a resonator
Let \(\Omega\) be an exterior of a bounded domain. The self-adjoint operator \(H=-\Delta\) with Dirichlet boundary conditions on \(\partial \Omega\) is studied in \(L^ 2(\Omega)\). A resonance \(\phi\in L^ 2(\Omega)\) is defined as a vector which is concentrated in some bounded domain \(B\subset \Omega\) and such that the spectral measure \((E_ H ...openaire +2 more sources
Surface Science Letters, 1982
Abstract Localized electron states in oxides adjacent to metals hybridize with conduction electron states forming interface states, which at the localized site have an amplitude resonantly enhanced over the amplitude of the conduction electron states.

Anti-Resonance — Velocity Resonance
Mekhatronika, Avtomatizatsiya, Upravlenie, 2019The task of the study is to establish the nature of mechanical resonance, namely, it is a resonance of forces or speeds. Two definitions are introduced. Definition 1. Resonance of forces is a resonance arising at a frequency ω = (k/m)0,5 in a mechanical system including an inert body and an elastic element, at which the reactive forces developed by ...

Resonance—Nuclear Magnetic Resonance
2019In this chapter, we will consider the principles of nuclear magnetic resonance to see how it can be exploited to generate signals from within the body related to the presence and properties of water within tissues. We will explore how radiofrequency waves can be used to exploit resonance phenomenon of protons placed within a magnetic field and the ...
