Density: graphite's specific gravity is 2. 3, which makes it lighter than diamonds.

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 ).

In 2007 Vagrant formed another imprint label, Density Records, which will release heavier material than has traditionally been released on the label.

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.

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.

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.

Barangays Rosario, which includes contested areas between Municipality of Tagoloan and Municipality of Malitbog, Bukidnon and Sta Cruz, occupy relatively bigger areas ( 11. 2 %) than the other nine barangays. The Gross Population Density of Tagoloan in 2004 is 650 persons per square kilometer.

" Lisa's Date with Density " is the seventh episode of the animated television series The Simpsons < nowiki >'</ nowiki > eighth season, which originally aired December 15, 1996.

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.

For these reasons, the keraunic number has been replaced by more accurate Flash Density maps, which collect data from both ground-based and satellite lightning detectors.

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.

Video High Density ( VHD ) was a videodisc format which was marketed predominantly in Japan by JVC.

Density functional methods have been applied to investigate the transimination reaction, and the results have shown that the reaction involves three sequential steps: ( i ) formation of a tetrahedral intermediate with the active site lysine and the amino substrate bonded to the PLP cofactor ; ( ii ) nondirect proton transfer between the amino substrate and the lysine residue ; and ( iii ) formation of the external aldimine after the dissociation of the lysine residue.

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

Density of ice increases slightly with decreasing temperature and has a value of 0. 9340 g / cm³ at − 180 ° C ( 93 K ).

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.

Lisa has been friendly with several boys, including Ralph Wiggum in " I Love Lisa " ( season 4, 1993 ), Nelson Muntz in " Lisa's Date with Density " ( season 8, 1996 ) and Colin in The Simpsons Movie ( 2007 ).

Nelson shows the occasional glimpse of humanity, though, and other characters have occasionally warmed to him ; Lisa dates him briefly in " Lisa's Date With Density ", Marge informally adopts him in " Sleeping with the Enemy ," and Bart is shown as a friend to him several times, such as in " The Haw-Hawed Couple.

" Lisa's Date with Density " ( season eighth, 1996 ) was the first episode to center around Nelson and was used to explain why he acts the way he does.

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

Above the viewfinder is a filter bar used to slide a green or an orange filter in front of the lens ; starting with the BL, there is only a Neutral Density filter.

A book, ' The Fundamentals of Density Functional Theory ' written by H. Eschrig, contains detailed mathematical discussions on the DFT ; there is a difficulty for N-particle system with infinite volume ; however, we have no mathematical problems in finite periodic system ( torus ).

Density ( normalized to average density ) versus radius ( normalized to external radius ) for a polytrope with index n = 3.

It's Density is 770 kg / m³ and with color golden to dark brown.

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.

In August 1989, Apple introduced the Macintosh SE FDHD with the new SuperDrive, a floppy disk drive that could handle 1. 4 MB High Density ( HD ) floppy disks.

Originally marketed as FDHD ( Floppy Disk High Density "), later some Macintosh SE FDHDs were labeled Macintosh SE Superdrive, to conform to Apple's marketing change with respect to their new drive.

On the below half, rendered with Density Estimation, the noise is smoothed out without destroying the sharp edges.
