Non-uniform Euler-Bernoulli beams’ natural frequencies [PDF]
Ingeniería e Investigación, 2011 This paper has studied the problem of natural frequencies for Euler-Bernoulli beams having non-uniform cross-section. The numerically-obtained solutions were compared to asymptotic solutions obtained by the Wentzel-Kramers-Brillouin (WKB) method.

Why frequencies are natural [PDF]
Behavioral and Brain Sciences, 2007 AbstractResearch in mathematical cognition has shown that rates, and other interpretations of x/y, are hard to learn and understand. On the other hand, there is extensive evidence that the brain is endowed with a specialized mechanism for representing and manipulating the numerosities of sets – that is, frequencies.

Nested Sets and Natural Frequencies. [PDF]
, 2019 Is the nested sets approach to improving accuracy on Bayesian word problems simply a way of prompting a natural frequencies solution, as its critics claim? Conversely, is it in fact, as its advocates claim, a more fundamental explanation of why the natural frequency approach itself works?

Axisymmetric Natural Frequencies of Statically Loaded Annular Plates [PDF]
Shock and Vibration, 2003 We present a numerical procedure to solve the axisymmetric vibration problem of statically loaded annular plates. We use the von Kármán nonlinear plate model to account for large deformations and study the effect of static deflections on the natural ...
