The dynamics of an experimental electrodynamic loudspeaker is studied by using the tools of chaos theory and time series analysis. Delay time, embedding dimension, fractal dimension, and other empirical quantities are determined from experimental data. Particular attention is paid to issues of stationarity in a system in order to identify sources of by: 3. Stamenphone is a musical sculpture that sounds like an ethereal Chinese instrument.

Before acoustic telemetry, the oil rig industry has relied on low rate transmission methods such as mud pulse telemetry, which can only support less than bps even on real drill pipes.

Therefore, this project demonstrates the feasibility of faster transmission rate through drill Author: Leong Chee Ho. designed to receive or transmit radio signals.

For over a decade, the application of acoustic radiation force (ARF) has been proposed as a mechanism to increase ultrasonic molecular imaging (MI) sensitivity in ted herein is the first noninvasive in vivo validation of ARF-enhanced MI with an unmodified clinical system.

Portraying a wide range of genres (rock, dance, TV soundtracks, country, pop, soul, easy listening, Turkish Arabesk), the essays cover methodology, modernism, postmodernism, Marxism and communication.

The main contribution of this work was to use Pitot-tube probe, hot-wire anemometry and far-field acoustic measurements to perform an experimental characterization of velocity and acoustic fields of single-stream subsonic jets operating at Machand Cited by: 4.

by:   A single beam acoustic device, with its relatively simple scheme and low intensity, can trap a single lipid droplet in a manner similar to optical tweezers.

Forces in the order of hundreds of nanonewtons direct the droplet toward the beam focus, within the range of hundreds of micrometers.

This trapping method, therefore, can be a useful tool Cited by: Data from experimental and simulated data were obtained and normalized to the maximum value found for each case in order to performa quantitative comparison.

Both acoustic fields show the acoustic pressure distribution in water. Figure 5 shows the same acoustic field characterized and simulated over three different planes in the space. Microphone arrays are useful for measuring acoustic energy quantities (e.g. acoustic intensity) in the near-field of a full-scale solid rocket motor.

According to FAA Advisory Circular C and 14 CFR Part 36 Amendment issued inentities seeking changes to original type certificates or new supplemental type certificates for most helicopters must demonstrate compliance with either Stage 1 or Stage 2 noise limits.

In music, an aria is a violin solo. Is it true or false. Check Your Knowledge at   The air chamber is treated as a boundary value problem which results in the solution of the wave equation for the general case in which the horn throat enters the air chamber in any circumferentially symmetrical manner.

The following specific cases are analyzed: (1) the case in which the horn throat enters the air chamber by means of a single orifice, (2) the horn throat enters the air Cited by: 8. In signal detection theory it is advantageous to get a noise profile because most signals are made up of the signal plus noise.

Profiling the noise helps identify the background noise that needs to be filtered out and to also detect false alarms. In contrast to Crookes’ radiometer, which rotates due to electromagnetic radiation, the analogous acoustic radiometer demonstrates radiation pressure.

The apparatus consists of two panes attached to opposite ends of a horizontal arm that is pivoted at its center. One side of either pane is acoustically reflective and the other absorptive. The apparatus rotates when placed in an enclosure of Cited by: 4.

A primary source is a work that is being studied, or that provides first-hand or direct evidence on a topic.

Common types of primary sources include works of literature, historical documents, original philosophical writings, and religious texts. Comparing the energy spectrum between the magnetosphere and the ionosphere for the period with the pulsating aurora, the electron fluxes from a few keV up to keV are almost same between them.

This means that the pitch angle scattering occurred in the strong diffusion [ Kennel, ] in which the flux between inside/outside the loss cone.

We don’t create electric violins to replace acoustic violins. Of course, electric violins create a small sound without amplifier, and you can use it to tune your electric violin. voltage between those two points. A neon circuit tester is a little neon light bulb that glows orange when it's touched to a point in the circuit where the voltage is above the ignition voltage of the neon, typically something like 70 volts, I think.

But it can't tell you how MUCH above that voltage. A COUSTICAL EXAMINATIONS of the violin family extend over of its more than years but the instruments still defy analysis and complete understanding.

Imagine a glowing greenish-white sheet that keeps on changing its shape, just like a shimmering curtain gently blown by the. The formation of signals in the receiving channel of the recording system is assumed to be described by the linear procedure of convolution (Duhamel’s integral) in the first approximation.

The design of the noisy version of the Numbers corpus was heavily influenced by Aurora 2. However, we believe that the Numbers corpus makes it easier than Aurora 2 to make a distinction between development data used to make design choices or adjust system parameters and evaluation data used to report final results.
