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 is related to pressure by the ideal gas laws.

* Densities of the elements ( data page ) — Density ( solid, liquid, gas )

Density is often expressed in grams per cubic centimeter ( g / cm < sup > 3 </ sup >).

Density is an intensive property in that increasing the amount of a substance does not increase its density ; rather it increases its mass.

Density is highest in the southwest where Colombo, the country's main port and industrial center, is located.

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

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.

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 ").

Whistling a bar of " Density 21. 5 " is a traditional musical quote.

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.

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.

" Just as the Power Spectral Density ( PSD ) is the Fourier transform of the auto-covariance function we may define the Cross Spectral Density ( CSD ) as the Fourier transform of the cross-covariance function.

Density functional theory ( DFT ) is a quantum mechanical modelling method used in physics and chemistry to investigate the electronic structure ( principally the ground state ) of many-body systems, in particular atoms, molecules, and the condensed phases.

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 of board when evaluated in relation to density of the fiber that goes in to making of the panel is important.

It is a hybrid of Philips and Sony's MM-CD ( Multi-Media Compact DIsc ) format and Toshiba's SD ( Super Density ) format.

Density tools also have an extendable caliper arm, which is used to measure the true width of the borehole.

This is a Pretty Cool Drink, giving you the errors compensated for between the speeds Position, Compression and Density

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

Density dependence is the regulator process that allows the population to return to equilibrium after a perturbation.

This spacing is called Normal Density.

Density remains important today, for smart phone apps and for Java apps downloaded into browsers over slow internet connections.

Delta-sigma modulation converts the analog voltage into a pulse frequency and is alternatively known as Pulse Density modulation or Pulse Frequency modulation.

Density of settlements in the central region decrease, as late Zarubintsy groups appear radially, especially southward into the forest-steppe regions of the middle Dnieper, Desna and southern Donets rivers.

* Density: 22. 798 Phones / 100 Hab

Most quantitative calculations in modern quantum chemistry use either valence bond or molecular orbital theory as a starting point, although a third approach, Density Functional Theory, has become increasingly popular in recent years.

Density functional methods and semi-empirical methods are variants on the major theme.

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.

So by reducing the number of tracks used and thus capacity, it was possible to further reduce cost-in contrast to Double Density drives used e. g. in IBM PC computers of the day which saved 180 kB on one side ( by using a 40 tracks format ).

* Electric Dipole Potential by Stephen Wolfram and Energy Density of a Magnetic Dipole by Franz Krafft.

Density of loading refers to the mass of an explosive per unit volume.

Density was checked as development was occurring.

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

Density and temperature of plasma in the magnetosphere and other areas of space.

Density increases upwards, temperature increases towards the right.

: Density operators are those that are in the closure of the convex hull of the one-dimensional orthogonal projectors.

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 1989 he and Yang published Density Functional Theory of Atoms and Molecules, now considered the basic textbook on DFT.
