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.

Effect of Damping on the Natural Frequencies of Linear Dynamic Systems [PDF]
, 1961 An analysis is presented of the effect of weak damping on the natural frequencies of linear dynamic systems. It is shown that the highest natural frequency is always decreased by damping, but the lower natural frequencies may either increase or decrease,

Quantum communication in the presence of a horizon [PDF]
, 2014 Based on homodyne detection, we discuss how the presence of an event horizon affects quantum communication between an inertial partner, Alice, and a uniformly accelerated partner, Rob.

Frequency of metamerism in natural scenes [PDF]
Journal of the Optical Society of America A, 2006 Estimates of the frequency of metameric surfaces, which appear the same to the eye under one illuminant but different under another, were obtained from 50 hyperspectral images of natural scenes. The degree of metamerism was specified with respect to a color-difference measure after allowing for full chromatic adaptation.

Simplified analysis of structures using applied element method [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2021 The Applied Element Method (AEM) is a numerical method of structural analysis. The degrees of freedom are located at the centroid of an element, which is rigid. In AEM, many pairs of springs are provided on the faces of the element. Although the AEM is

Improved two-dimensional cracked finite element for crack fault diagnosis
Computer Assisted Methods in Engineering and Science, 2017 In this paper the two-dimensional finite element with an embedded edge crack proposed by Potirniche et al. (2008) is improved further for crack depth ratios ranging up to 0.9 and for predicting the natural frequency of a cracked beam more accurately ...
