An Introduction to Galaxies and Cosmology
The quantity pcnt(/) is known as the critical density at time /. Note that both pcnt(/)
and ff(t) vary with time, but, in the critical model. Equation 5.26 always relates
their variations. So, it is always possible to work out the current value of the
critical ...

The Origin and Evolution of the Universe
The critical density is very low — only 6 hydrogen atoms per cubic meter for Hu =
75 km/sec/Mpc. A very good laboratory vacuum (10~10 torr) has 4 x 1012 atoms
per cubic meter. While the critical density is low, the apparent density of the ...

Introduction to Modern Traffic Flow Theory and Control: The ...
The critical density and speed required for traffic breakdown are qualitatively
illustrated by dashed curves between states of free flow F and synchronized flow
S in the speed-density and flow-density planes shown in Fig. 3.9. These
definitions ...

This second way to write the cosmic evolution equation emphasizes the
importance of the critical density. If space has positive curvature, the actual
density of matter must be larger than the critical density. Likewise, a negative
curvature of ...

Chemical Thermodynamics
The experimental difficulty of determining critical behaviour from the shape of the
isotherm has led to a preference for determining the critical temperature and
pressure visually and the critical density by extrapolating liquid-vapour
equilibrium ...

Stellar Alchemy: The Celestial Origin of Atoms
summarised in the following way: • the critical density (T), i.e. that density which is
just sufficient to slow down the expansion of the Universe and bring it to a halt
after an infinite time, at least if the cosmological constant is zero: • the density of ...

Ad Hoc Networks: Third International ICST Conference, ...
In this paper, however, we conjecture that λ(1)c(dsup, r), defined by λ(1)c(dsup ,r)
def= p−11 (0.5;d sup ,r), (4) would yield a good estimate of the critical density.
Note that λ(1)c(dsup, r) ≤ λ(2)c(dsup ,r). We have found through simulation ...

Laser-Induced Breakdown Spectroscopy
With a p-polarized light obliquely incident on plasma surface, the radial
component of electric field resonates with plasma frequency and causes large
transfer of energy to electrons near critical density Nc surface. Critical density for
a given ...

FIGURE IT OUT 18.2 The “critical density,” pm, is defined to be that density of
matter that would allow the Universe to expand forever, but only just barely. lts
