con·duc·tance (G),

(kon-dŭk'tants),
1. A measure of conductivity; the ratio of the current flowing through a conductor to the difference in potential between the ends of the conductor; the conductance of a circuit is the reciprocal of its resistance.
2. The ease with which a fluid or gas enters and flows through a conduit, air passage, or respiratory tract; the flow per unit pressure difference.

In Figure 2 we show the behavior of the first three cumulants (denoted with double brackets) of the thermal conductance, as a function of the systems length, of both the WD (full line) and BdG classes DIII (dashed line) and CI (dotted line) for the case of a single channel in each lead.
where [U.sub.st] and [U.sub.meas] are the thermal conductances of the STPV window under standard conditions (e.g., NFRC 2014b) and test conditions, respectively, and [h.sub.o,st] and [h.sub.o,meas] are the exterior convective film coefficients under standard conditions and test conditions, respectively.
Here, Gs (T) is an augmented temperature-dependent thermal conductance matrix (contains thermal conductance in solids and HTCs between solids and fluids), T is a temperature profile vector of thermal grids, and P is the power profile vector in solids.
As compared to the density dependent thermal conductivity of typical silica aerogels prepared from TEOS, 18 x [10.sup.-3] W[m.sup.-1] [K.sup.-1] at 0.2g [cm.sup.-3] [7], coal gangue derived silica aerogel displays higher thermal conductance, which is close to the reported waterglass-based aerogels [31].
In Europe, it is common to describe the materials by their thermal conductance, or U-value, which is the thermal conductivity ([lambda] in units of W [m.sup.1] [K.sup.-1]) divided by the thickness (usually in units of W [m.sup.2] [K.sup.-1).
The thermal conductance for the topping slab was 1.4 W/mK (0.81 Btu/hFft).
In this equation, exponent n represents well-known heat transfer rates: the Newtonian heat transfer rate (n = 1), the radiative heat transfer rate (n = 4), and so on; [k.sub.h] is the thermal conductance at the hot side of the engine; [T.sub.H] is the temperature of the hot reservoir; and [T.sub.h] is the temperature of the working fluid at the hot side of the engine.
In addition to its low power requirements, the sensor does not require the frequent calibration used in conventional thermal conductance measurement techniques.
Contributions from the Aerospace Corporation present a universal bivariate Weibull model for reliability forecasting, a model for estimating separator forces during ball speed variation, a vacuum test rig for measuring thermal conductance, and a comparison of thermal conductance in spacecraft ball bearings.
In general, thermal conductance is the quantity of heat passing through the material of a unit area in a specified unit of time.
