The

fundamental frequencies of pre-stressed concrete beams for three different distances were computed.

Comparing the spectrums of a rotor system with pedestal looseness in the literature [3, 4], the spectrum not only contains the

fundamental frequencies of inner and outer rotor, 1/2 fractional harmonic components, but also contains sum frequency and difference frequency of two rotors'

fundamental frequencies, and superharmonic frequencies (such as 2X, 3X, and 4X) are presented.

The primary focus of this article is to compare the

fundamental frequencies between specimens with the subflooring attached to joists using 8d common nails, TetraGrip subfloor fasteners, and 8d common nails with an adhesive.

The use of microtremors was later extended to the study of dynamic parameters of buildings, for instance for identification of their

fundamental frequencies and of the possible danger of soil-structure resonance (Mucciarelli et al.

The next novelty is to explore

fundamental frequencies of speakers, i.

Initially, the two-tone input was producing two tones of amplitude A at

fundamental frequencies [alpha] and [beta] and two IM products of amplitude C at frequencies (2[alpha]-[beta]) and (2[beta]-[alpha].

The

fundamental frequencies of the two voices were very similar in Experiment 2, thus we can draw a preliminary conclusion that the differences shown between male and female voices are attributed to their differences in frequency that, in natural speaking, are usually greater than the differences between the two artificial voices used here.

He excites one note electromagnetically at one of its

fundamental frequencies, then uses the interferometer to visualize which areas of the playing surface reverberate.

Within a natural population, the

fundamental frequencies (F0s) of individual hums differ within a range of about 10 Hz.

The first is a Voice Range Profile (VRP), which provides the singer with his/her range of dynamics over a full range of

fundamental frequencies.

After evaluating the equipment at the

fundamental frequencies, the range is expanded to include frequencies from 0.
