In particular, the temperature increase caused by the superposition of any two waves is not the sum of temperature increases caused by each of the waves separately, which is to say that the principle of superposition, a signature of linear systems, is clearly violated. Consideration of the ...
The improved QCD light-cone sum rule (LCSR) provides an effective way to dealwith the heavy-to-light transition form factors (TFFs). Firstly, we adopt thei... HB Fu,XG Wu,HY Han,... - 《Nuclear Physics B》 被引量: 18发表: 2013年 ...
To assess how well these microscopic calculations compare with our measured data, Fig.6ashows the experimental ring-down times for the monolithic MoS2cavities described earlier (see Fig.1). The sum of the anharmonic and surface roughness losses are in very good agreement with experiment for the ...
and the term y(n)∙ x/|x|2 in brackets can be ignored, unless, as will be shown below, the sum of the source amplitudes is zero. However, the dependence on y(n) in the complex exponential cannot be ignored because it can dominate the result if some phase cancelation occurs in the...
Position calibration in the deep sea is typically done by means of acoustic multilateration using three or more acoustic emitters installed at known positions. Rather than using hydrophones as receivers that are exposed to the ambient pressure, the sound signals can be coupled to piezo ceramics glue...
(4), in which \({\sum }_{i=1}^{N}{a}_{i}^{(L)}=1\). The system determines the final prediction based on the decision rule described by Eq. (5) which returns the class associated with the highest probability. $$y \approx \hat{y} = g\left( {\user2{X}\left| \theta \...
(1seach) and loudspeaker excitation measurements (3seach) were performed using allnomicrophones at once. Subsequently, the cross-correlation between allnirecorded channels was evaluated according to therule of two[69]. Based on the measured sweep signals and the noise signal, the rule of two ...
(g\)with respect to the network parameters\({{{\boldsymbol{\theta }}}\)and then use of these derivatives to update the network parameters in the direction that reduces the overall loss\(g\), i.e., the negative gradient direction. The standard gradient-descent update rule for the weights...
Therefore, the precision defined as the ratio of true positives to the total of false and true positives (Knight et al., 2017) was the main selection criterion for an optimized threshold rule. We only considered threshold rules leading to the terminal node of a model that provided the ...
If we observe our H ≥ 10λ rule of thumb, we see that frequencies as low as 75 Hz in 200 m of water (the shelf break) and 15 kHz at 1 m depth (the surf zone) are reasonably amenable to a ray theory description. This is a pretty useful range of frequencies for applied systems...
