Each dual tone is composed of a low frequency (697, 770, 852, or 941 hertz) and a high frequency (1,209, 1,336, or 1,477 hertz), which are sensed and decoded at the switching office.
This paper is devoted to a theory of gas solubility in highly asymmetrical mixed solvents composed of a low molecular weight (such as water, alcohol, etc).
The science instrument is composed of a low frequency radiometer, including electrically-short, tapered, bi-conical dipole antennas, a receiver, and a digital spectrometer.
The system is composed of a low power visible laser (semiconductor or He Ne), focusing system, rotating mirror scanner, detection optics and amplifier, control unit for signal processing, speed control and data delivery to the process control unit.
Composite TBC microstructures composed of a low thermal conductivity/high temperature stable cubic Low-k matrix phase and a durable t′ Low-k secondary phase were deposited via APS.
A floor piece, dated 1990-2003, is composed of a low steel trough, into which melted candle wax was poured; there, the wax hardened around the bases of nine tiny sculptures, in unfired clay, of indistinct figures and faces that are reminiscent of the sorts of prehistoric totem that archeologists, in despair, assign to "ceremonial use".
A 3D printing method was developed based on the extrusion of bio-inks composed of a low-methoxylated pectin gel and embedded lettuce leaf cells.
The two-stage design is composed of a low-noise common-gate stage and a gain-boosting cascode block with an integrated output buffer for measurement.
In the present study, we developed a novel virus-like particulate peptide nucleotide dual vaccine (PNDV) of hTERT, which was composed of a low-affinity epitope variant with encoding full-length gene in the same virus-size particulate.
Aside from the performance comparison between the multi-high-frequency controller and traditional control methods for FIV, detailed experiment has also been carried out to study the effects of some key parameters of the proposed controller, which is composed of a low-frequency active resonator and a hard limiter.
Figure 2 shows the result of level DWT, which is composed of a low-resolution image of level and a set of wavelet coefficients from level to level.
