Investigation into the integration of a resonant tunnelling diode and an optical communications laser: model and experiment [PDF]
, 2007 A resonant tunnelling diode has been monolithically integrated with an optical communications laser [the resonant tunnelling diode (RTD-LD)] to form a simple optoelectronic integrated circuit (OEIC) that is a novel bistable device suitable for an optical

Characteristics of a 9mm triple-beam tuning fork resonant sensor [PDF]
, 2007 This paper describes the design and testing of the first miniaturised metallic triple-beam tuning fork resonant sensors for use in force, pressure and torque measurement applications. The new devices with 9mm length vibrating tines have resulted in over

The Modified “Stiffened” Drnevich Resonant Column Apparatus
Soils and Foundations, 1990 The original Drnevich Resonant Column apparatus has been designed for testing cylindrical soil specimens with maximum longitudinal and torsional stiffnesses corresponding to approximate resonant frequencies 285 Hz and 318 Hz, respectively. This apparatus has been modified successfully and its stiffness has been increased to over threefold in the ...

Two-to-one resonant multi-modal dynamics of horizontal/inclined cables. Part II : internal resonance activation, reduced-order models and nonlinear normal modes [PDF]
, 2007 Resonant multi-modal dynamics due to planar 2:1 internal resonances in the nonlinear, finite-amplitude, free vibrations of horizontal/inclined cables are parametrically investigated based on the second-order multiple scales solution in Part I [1].

MODELING OF RESONANCE EFFECTS IN SPINE WITH ADDITIONAL FIXING ELEMENTS [PDF]
Научно-технический вестник информационных технологий, механики и оптики, 2019 Subject of Research. We study the procedure of natural frequencies calculation for a system consisting of a human spine with fixing elements. Resonant effects can occur in the vicinity of such system leading to stability violation or structure ...

Calibration and limitations of a fixed-partly fixed resonant column apparatus [PDF]
E3S Web of ConferencesThe small-strain shear modulus of soils and rocks is an important input parameter in geotechnical analyses. Its estimation using the resonant column apparatus relies on accurate knowledge of the rotational inertia of the apparatus’s active end.

Parametric resonance in concrete beam-columns [PDF]
Latin American Journal of Solids and Structures, 2014 A dynamic instability, called parametric resonance, is exhibited by undampedelastic beam-columns when under the action of pulsating axial force. The scope of the existing theory of parametric resonance is restricted to physically linear beam-columns undergoing finite lateral displacements.
