* Density altitude is the altitude corrected for non-ISA International Standard Atmosphere atmospheric conditions.

* Density altitude – the density of the air in terms of altitude in the International Standard Atmosphere

Density and pressure decrease smoothly with altitude, but temperature ( red ) does not.

* Density altitude

Density altitude is the altitude in the International Standard Atmosphere at which the air density would be equal to the actual air density at the place of observation, or, in other words, the height when measured in terms of the density of the air rather than the distance from the ground.

" Density Altitude " is the pressure altitude adjusted for non-standard temperature.

Density contrasts between different sedimentary layers, such as between sand and clay, can result in flame structures or load casts, formed by inverted diapirism.

Density contrasts can also cause small-scale faulting, even while sedimentation goes on ( syn-sedimentary faulting ).

In excited states, chemical reactions or when a more accurate representation is needed, electronic behavior can be obtained from first principles by using a quantum mechanical method, such as Density Functional Theory.

One can prove that this periodogram converges to the true PSD when the averaging time interval T goes to infinity ( Brown & Hwang ) to approach the Power Spectral Density ( PSD ).

All drives can read and write 1. 44 MB and 720 KiB MFM floppies, as used on PCs, Apple Macintoshes ( High Density format only, see below ), and many workstations.

Density can then be calculated according to a molar form of the original formula:

Density can also refer to:

Density functional theory simulations predict that depositing certain adatoms on graphene can render it piezoelectrically responsive to an electric field applied in the vertical ( i. e. out-of-plane ) direction.

Density matrices acting on H < sub > A </ sub > only constitute a proper subset of the operators on H < sub > A </ sub > and same can be said for system B.

Conversion of Cineon Printing Density ( CPD ) to Status-M can be estimated with a 3x3 matrix or by using tables contained in the Kodak " Digital LAD " document.

The most common reliability parameter is the mean time to failure ( MTTF ), which can also be specified as the failure rate ( this is expressed as a frequency or Conditional Probability Density Function ( PDF )) or the number of failures during a given period.

An optical jukebox is a robotic data storage device that can automatically load and unload optical discs, such as Compact Disc, DVD, Ultra Density Optical or Blu-ray disc and can provide terabytes ( TB ) and petabytes ( PB ) of tertiary storage.

Density functional theory ( DFT ) methods are often considered to be ab initio methods for determining the molecular electronic structure, even though many of the most common functionals use parameters derived from empirical data, or from more complex calculations.

By 1978 Parr had realized that Density Functional Theory ( DFT ) would be extremely useful in quantitative calculations of chemical and biological systems, especially those with high molecular weights.

In " Lisa's Date With Density ", Nelson kisses Lisa, only to be berated by Jimbo, Kearney, and Dolph, who believe that kissing girls is " gay " ( Despite the events that occurred revolving around Jimbo in " New Kid On The Block ").

At increased Density Altitude, for the same given indicated airspeed the aircraft's true airspeed ( TAS ) will be higher, but the same indicated airspeed limits ( IAS ) apply.

* Density: The media should be denser than the material being ground.

Density Separations may be created by printing three prints of the same picture, each at a different exposure time that will be combined for the final image.

Density, Bulk Density, or Wet Density,, are different names for the density of the mixture, i. e., the total mass of air, water, solids divided by the total volume of air water and solids ( the mass of air is assumed to be zero for practical purposes ):

These may be heuristics-based such as the Extended Kalman Filter or the Assumed Density Filters described in Peter S. Maybeck's book or more methodologically driven such as the projection filters introduced by Damiano Brigo, Bernard Hanzon and François Le Gland, some sub-families of which are shown to coincide with the Assumed Density Filters.

Density is desirable as weights must be as small as possible, in order to minimize visual cues which could drive fish away from a fishing operation.

C < sub > 60 </ sub > with isosurface of ground state electron density as calculated with Density functional theory | DFT

Density is not measured directly but is calculated from measurements of temperature, pressure and humidity using the equation of state for air ( a form of the ideal gas law ).

Density varies from 1 person per square kilometre ( 3 per sq.

Density of eastern towhees was found to decline with distance from the edge of a power line right-of-way and an oak-hickory forest in eastern Tennessee.

DE-15 is also conventionally called RGB connector, D-sub 15, mini sub D15, mini D15, DB-15, HDB-15, HD-15 or HD15 ( High Density, to distinguish it from the older and less flexible DE-9 connector used on some older VGA cards, which has the same shell size but only two rows of pins ).

Density ranges from 0. 917 g / cc to 0. 933 g / cc.

Allmusic's Sean Hickey says, " According to the composer, Density 21. 5 is based on two melodic ideas — one modal, one atonal — and all of the subsequent material is generated from these two themes.

* Stereophile magazine names the best recordings, including " EDGARD VARÈSE: The Varèse Record Ionisation, Density 21. 5, Interpolations from Déserts, Octandre, Intégrales "

Another form of light weight row cover is made from High Density Polyethylene ( HDPE ) and is a knitted fabric.

Population Density of Buildwas from 1880 to 1960.

For these reasons, the keraunic number has been replaced by more accurate Flash Density maps, which collect data from both ground-based and satellite lightning detectors.

Density of the tuff ranges from fine-grained to aphanitic and is densely welded.

Equivalent Circulating Density ( when forward circulating ) is defined as the apparent fluid density which results from adding annular friction to the actual fluid density in the well.
