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 ...
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]).
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 ...
Absolute thermal resistance is the temperature difference across a structure when a unit of heat energy flows through it in unit time. It is the reciprocal of thermal conductance . The SI unit of absolute thermal resistance is kelvins per watt (K/W) or the equivalent degrees Celsius per watt (°C/W) – the two are the same since the intervals ...
The net flux is thus the difference of the energy fluxes: = , , Since both fluxes are dependent on T 1 and T 2, the relationship between the flux and the temperature difference can be used to determine the thermal interface resistance based on:

(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 ...
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 ...
