	DRAFT
		The purpose of an air admittance valve is to provide a method of allowing air to enter the plumbing drainage system without the use of a vent extended to open air and to prevent sewer gases from escaping into a building.
		The air admittance valve shall be rated for the size of the vent to which the valve is connected.
		The air admittance valve shall only vent fixtures that are on the same floor level and connect to a horizontal branch drain with a maximum of four branch intervals.

	Parallel Resonant Circuits
		The general case is rather complex, but the special case where the resistances of the inductor and capacitor are negligible can be handled readily by using the concept of admittance.
		The admittance has its most obvious utility in dealing with parallel AC circuits where there are no series elements.
		The equivalent admittance of parallel elements is the sum of the admittances of the components.

	Admittance (Site not responding. Last check: )
		The SI unit of admittance is the siemens.
		Admittance, just like Impedance, is therefore a complex number, made up of a real part (the conductance, G), and an imaginary part (the susceptance, B), shown by the equation:
		Similar to the electrical meanings of admittance and impedance, an impedance in the mechanical sense can be thought of as the "inverse" of admittance.

	Admittance - Deeds in Depth - Skills Resources - Manuscripts & Special Collections- The University of Nottingham
		The technically correct legal term is 'admittance', although by the nineteenth century the word 'admission' was often used in its place, even by stewards of the courts.
		Admittances begin by stating the type of court, the name of the Lord of the Manor, and the date.
		The record of their admittance was often followed immediately by a surrender of the land back to the Lord of the Manor, to the use of a purchaser, trustee or mortgagee.

	Admittance Matrix of Asymmetric Piezoelectric Bimorph with Two Separate Electrical Ports Under General Distributed Loads (Site not responding. Last check: )
		ABSTRACT The dynamic admittance matrix of the asymmetric triple-layer piezoelectric bimorph subjected to the general distributed harmonic loads as well as the flexural moments and the vertical loads at the tip are presented.
		The derived admittance matrix under the cantilevered condition is presented by a five-by-five matrix, each row representing the relationships of the displacement and rotation at the tip, the volume averaged displacement, the separate electrical charges with the flexural moment and vertical load at the tip, the magnitude of the distributed load, and the voltages.
		It is shown that the derived admittance matrix covers the various boundary conditions, the electrical parallel and series connections, and the arbitrary lay-up, including the unimorph, used as both sensors and actuators.

	Building a Synthetic Guitar Bridge Admittance
		Each peak in the admittance curve corresponds to a resonance in the guitar body that is well coupled to the strings via the bridge.
		Thus, a complete bridge model requires not only a synthetic bridge admittance which determines the reflectance ``seen'' on the string, but also a separate filter which models the transmittance from the bridge to the outside air; the transmittance filter normally contains the same poles as the reflectance filter, but the zeros are different.
		The frequency, complex amplitude, and width of each peak in the measured admittance of a guitar bridge can be used to determine the parameters of a second-order digital resonator in a parallel bank of such resonators being used to model the bridge impedance.

	Science Fair Projects - Admittance
		In electrical engineering, the admittance (Y) is the inverse or reciprocal of the impedance (Z).
		Just as impedance is complex resistance, and the conductance G is the inverse G = 1/R of resistance R, admittance is also complex conductance.
		Likewise, admittance is made up of a real part (the conductance), and an imaginary part (the susceptance B), shown by the equation

	Chapter Administrate <i>to</i> Adnominal of A by Webster's Dictionary (1913 Edition)
		Admittance is now chiefly confined to its primary sense of access into some locality or building.
		Thus we see on the doors of factories, shops, etc. "No admittance." Its secondary or moral sense, as "admittance to the church," is almost entirely laid aside.
		So, when we speak of admission to a concert or other public assembly, the meaning is not perhaps exactly that of admittance, viz., access within the walls of the building, but rather a reception into the audience, or access to the performances.

	Lightning ground system attachable admittance testing instrument - Patent 4142143
		(h) when said switch is closed directly coupling said reference winding to the input of said amplifier said averaging means indicates the resistive component of admittance and when said switch is open coupling said reference winding through said capacitor to the input of said operational amplifier said averaging means indicates the reactive component of admittance.
		The present invention overcomes these problems by providing an admittance measuring instrument that is particularly useful for testing lightning ground systems in that it provides reliable test information without interruption of the ground system.
		The ac signal is detected using a synchronous detector with reference derived from the transmitter, either in phase to measure the resistive component, or with a 90.degree.

	[No title]
		Commonly called Durgo valves air admittance valves are designed to decrease the number of pipes that need to penetrate the roof and walls of a property.
		Air admittance valves, when installed, must finish above the highest flood level of the space the valve is in...I.E. If the valve is in the same room as a wash hand basin, it must be higher than the overflow of that basin.
		The use of air admittance valves are governed by building regulations and cannot be used in all cases.

	Air Admittance Valves
		Air admittance valves (AAVs) are pressure-activated, one-way mechanical vents, used in a plumbing system to eliminate the need for conventional pipe venting and roof penetrations.
		Although this method is simple and reliable, it requires each plumbing fixture to have a lateral return vent that passes through wall studs to a central stack, or to have its own vertical vent that passes through the wall, ceiling, attic, and roof.
		Because air admittance valves eliminate the need for vent stack penetrations and flashing at wall assemblies, attics, and roof decks, they mitigate the potential for air and water leakage due to vent stack penetrations.

	ABLE level measurement using rf admittance probes.
		R.F. Admittance is a measurement technology used for determining level of liquids, granulars, slurries and interface in almost any containment and process environment.
		To draw an analogy, this would be similar to comparing a calculator with a PC, both the calculator and the PC will perform simple tasks but only the PC will provide an efficient solution to a complex problem.
		Despite coating build ups, changes in density or electrical properties, the R.F. Admittance level measurement will not be affected, even if all are acting at the same time.

	ISA \| Analysis of The Frequency Response Curve of A Differential-type Electrostatic Actuator - SICON 2002
		Also the admittance of the differential type actuator is derived taking the practical conditions into consideration, although it has no admittance in ideal case.
		IT is shown as a function of biasing error, driving error, and capacitive mismatch including parasitic capacitors The validity of the admittance model is proved by comparing the between the admittance model and the measured data.
		At the end, the distortion in the frequency response curve measured by a cap active sensor is analyzed and it is concluded that the admittance of the actuator is the main cause of this distortion.

		Admittance is measured in (guess what?) the unit of Siemens, and its symbol is "Y".
		Like impedance, admittance is a complex quantity rather than scalar.
		Again, we see a certain logic to the naming of this new term: while impedance is a measure of how much alternating current is impeded in a circuit, admittance is a measure of how much current is admitted.
