In this context of changing and challenging market requirements, Gas Insulated Substation GIS has found a broad range of applications in power systems for more than two decades because of its high reliability, easy maintenance and small ground space requirement etc. SF6 has been of considerable technological interest as an insulation medium in GIS because of its superior insulating properties, high dielectric strength at relatively low pressure and its thermal and chemical stability. SF6 is generally found to be very sensitive to field perturbations such as those caused by conductor surface imperfections and by conducting particle contaminants.
A-3 — the low- bit-rate codec used by Dolby Labs for the Dolby Digital video format. A — a standard method of tuning in which the note A above Middle C has a frequency of Hz cycles per second.
Previously, a variety of tuning methods were in existence, with A having frequencies ranging from Hz to Hz. ISO adopted this standard in Also called standard pitch or concert pitch. See bit-sliced arithmetic coding. See Advanced Audio Coding.
The underlying code designed by Avid that allows Pro Tools to communicate with computer hardware and software. Pro Tools is basically an user interface that tells the AAE which runs in the background what needs to be done. A and B rolls — the negative of an edited filmcut to correspond to a movieconsisting of two rolls, designated A and B, to allow for fades, dissolves, and other effects without using opticals.
The A roll has all the odd numbered shots, with black leader in place of the shots on the B roll, while the B roll has all the even numbered shots, with black leader in place of the shots on the A roll.
The negative is printed in three passes through the contact printer, one for each roll and another for the soundtrack. See also answer print. AAX comes in two versions: A-B — the procedure for comparing the sound of two different audio sources, by first listening to one source A and then quickly switching to the second B.
For the best accuracy, both sources should be at the same level. Ableton AG — a music software company based in Berlin, Germany, that produces and distributes the software program Ableton Liveas well as a collection of related instruments and sample libraries.
Ableton Live — a software music sequencer and digital audio workstation developed by Ableton. Unlike many other software sequencers, Live is designed to be an instrument that can be used in live performances, as well as a tool for composing, recordingarrangingmixingand mastering.
It is also used by deejayshaving controls for beatmatching, crossfading, and other effects. Abbey Road Studios is noted for its innovative recording techniques developed by its engineers in conjunction with the Beatles who recorded most of their albums and singles therePink Floyd, the Hollies, and other bands during the s.
The building began as a nine-bedroom townhouse built in the s, but was later converted to flats apartments. Inthe building was purchased by the Gramophone Company who converted it into recording studios. After the Beatles released their album entitled Abbey Road in Septemberthe studios received world-wide attention, and in the building was renamed Abbey Road Studios.
Inthe British government granted it historical status, preventing it from being sold to real estate developers. A-B powering — an essentially obsolete method of providing power for condenser microphonessimilar to phantom powerbut using the signal leads modulation leads.
As such it is incompatible with normal phantom power and potentially harmful to dynamic and ribbon microphones. It is also called Tonader powering, T-powering, parallel powering, and modulation lead powering. A-B recording — see A-B technique. See also relative grid mode.
For example, the measurment of a voltage is the number of volts above zero volts, while the height of a building is the distance from street level starting point to the top of the building.
In contract, a relative measurement is the measurement of a change in a quantity or in relation to another item or device. For example, the gain of an amplifier is the change in voltage from the input to output. In other words, a positive force on the microphone diaphragm will produces a positive force on the speaker conewhich means there must not be any change in polarity from the microphone signal, through the preamprecording mediumsignal processorsreproduction devices, amplifiersand speakers.
Real life sound never has inverted polarityit occurs only with reproduced sound. Many experts claim that inverted polarity sound introduces harsh sibilanceblurs preamp transients and fine details, and makes spoken words less intelligible.
Sometime called by the less technically correct term absolute phase.Figure Price and Average Cost at the Raspberry Farm In (a), price intersects marginal cost above the average cost curve.
Since price is greater than average cost, the firm is making a profit. 4) The average cost curves (AVC and ATC) should be minimized PLACE THIS ORDER OR A SIMILAR ORDER WITH LITE ESSAYS TODAY AND GET AN AMAZING DISCOUNT Share this.
Marginal cost, average variable cost and average fixed cost can be derived from a short-run production function subject to the law of diminishing returns.
From AFC and AVC to ATC. With the average variable cost, AVC (animate and pause) and average fixed cost, AFC (animate and pause), we can construct the average total cost, ATC.
Now, let’s put all of the average cost curves together N ti th f ll i C ATC AVC ATC = AFC + AVC Notice the following relationships between the average cost curves: 1 ATC > AVC B’ AFC AFC 1.
2. Minimum ATC is to the right (higher output) than minim m AVC AFC A’ than minimum AVC. A – a standard method of tuning in which the note A above Middle C has a frequency of Hz (cycles per second). In , ANSI adopted the standard establishing Hz for the pitch of A above Middle C.
Previously, a variety of tuning methods were in existence, with A having frequencies ranging from Hz to Hz.
ISO adopted this standard in International Journal of Engineering Research and Applications (IJERA) is an open access online peer reviewed international journal that publishes research.
