Augmented reality (AR) is a field of computer research which deals with the combination of real world and computer generated data. At present, most AR research is concerned with the use of live video imagery which is digitally processed and "augmented" by the addition of computer generated graphics. Advanced research includes the use of motion tracking data, fiducial marker recognition using machine vision, and the construction of controlled environments containing any number of sensors and actuators.


Momentum flux

Momentum flux, the rate of transfer of momentum across a unit area (N·s·m-2·s-1). (Newtonian fluid, viscous flow)
Heat flux, the rate of heat flow across a unit area (J·m-2·s-1). (Fourier's Law) [5] (This definition of heat flux fits Maxwell's original definition[4].)
Chemical flux, the rate of movement of molecules across a unit area (mol·m-2·s-1). (Fick's law of diffusion)
Volumetric flux, the rate of volume flow across a unit area (m3·m-2·s-1). (Darcy's law)
Mass flux, the rate of mass flow across a unit area (kg·m-2·s-1). (Either an alternate form of Fick's law that includes the molecular mass, or an alternate form of Darcy's law that includes the density)
