Linewidth and frequency jitter measurement of an erbium-doped fiber ring laser by using a loss-compensated, delayed self-heterodyne interferometer [PDF]
, 1992 The single-mode line width of erbium-doped, single-frequency, fiber ring laser has been measured by using a newly developed loss-compensated delayed self-heterodyne interferometer that has a resolution of less than 600 Hz.

Natural Frequency Prediction Method for 6R Machining Industrial Robot
Applied Sciences, 2020 The industrial robot machining performance is highly dependent on dynamic behavior of the robot, especially the natural frequency. This paper aims at introducing a method to predict the natural frequency of a 6R industrial robot at random configuration ...

Evaluation of sand p–y curves by predicting both monopile lateral response and OWT natural frequency
Studia Geotechnica et Mechanica, 2022 Extending the use of the p–y curves included in the regulation codes API and DNV to design large-diameter monopiles supporting offshore wind turbines (OWTs) was unsuccessful as it resulted in an inaccurate estimation of the monopile behavior.

Frequency shifts in natural vibrations in pantographic metamaterials under biaxial tests [PDF]
, 2017 In this paper a 2D continuum model, thought as the homogenized limit of a microstructured pantographic sheet, is studied. The microstructure is characterized by two families of parallel fibers, whose deformation measures account for bending, elongation ...

Frequency and phase modulation performance of an injection-locked CW magnetron. [PDF]
, 2006 It is demonstrated that the output of a 2.45-GHz magnetron operated as a current-controlled oscillator through its pushing characteristic can lock to injection signals in times of the order of 100-500 ns depending on injection power, magnetron heater ...

Weakly nonlinear nonaxisymmetric oscillations of capillary bridges at small viscosity [PDF]
, 2002 Weakly nonlinear nonaxisymmetric oscillations of a capillary bridge are considered in the limit of small viscosity. The supporting disks of the liquid bridge are subjected to small amplitude mechanical vibrations with a frequency that is close to a ...
