UVM agent classes are implemented as subclasses of the uvm_agent class, which itself is a subclass of uvm_component. Much like uvm_scoreboard, uvm_agent is lightweight in terms of class methods. Its only class methods are the "new" constructor and the "get_is_active" method. If the agent is being used to drive ports, get_is_active returns UVM ...
For example, a capacitor is composed of two isolated conductors and is charged by applying a difference in electron chemical potential. Slow equilibration : In some quasi-equilibrium situations it is possible to have two distinct populations of the same kind of particle in the same location, which are each equilibrated internally but not with ...
The canonical ensemble is the ensemble that describes the possible states of a system that is in thermal equilibrium with a heat bath (the derivation of this fact can be found in Gibbs [1]).
Typical Interfacial Resistance of Liquid Helium with metals. Resistance has been multiplied by T 3 to remove the expected T −3 dependence. Adapted from [9]. The presence of thermal interface resistance, corresponding to a discontinuous temperature across an interface was first proposed from studies of liquid helium in 1936.
The rate of heat flow is the amount of heat that is transferred per unit of time in some material, usually measured in watts (joules per second). Heat is the flow of thermal energy driven by thermal non-equilibrium, so the term 'heat flow' is a redundancy (i.e. a pleonasm).
The number of transfer units (NTU) method is used to calculate the rate of heat transfer in heat exchangers (especially parallel flow, counter current, and cross-flow exchangers) when there is insufficient information to calculate the log mean temperature difference (LMTD). Alternatively, this method is useful for determining the expected heat ...

(2) The derivation is limited to the following cases: (a) Two heat transfer mediums in countercurrent flow are changing in temperature in such a way that the decrease in sensible heat of one is equal to the increase in sensible heat of the other; or (b) One heat transfer medium is at a constant temperature, such as a condensing vapor or boiling ...
