The first two equations give the value of the given flux through a closed surface, and the second two equations give the value of a line integral around a loop. In this notation, ∇=(∂/∂x, ∂/∂y, ∂/∂z) E is the electric vector, B is the magnetic induction, ...

The Arrhenius equation kA = Ae− E/Rt has found numerous applications throughout chemical kinetics for diverse rate processes. This equation involves the assumption that the pre-exponential factor, A, does not vary with temperature. For simple reactions, deviations from this equation are usually ...
studies, due to the difficulty in measuring the surface heat flux variation, a Heat Flux Ratio (HFR) equation originally derived by Mick and Mayle [1], has been widely employed to calculate the surface heat flux distribution using the measured adiabatic film effectiveness and surface temperature....
In addition the flux through the boundary surface is given. The right hand side is regarded as a function of time. The mentioned problem is reduced to an integral equation. For this, in a particular case, an existence and uniqueness theorem is proved and an explicit form of the solution ...
through which all these new quantities satisfy a fundamental continuity equation. We experimentally verify our theoretical predictions by studying a movable object embedded in a disordered environment and by measuring the corresponding Fisher information flux at microwave frequencies. Our results improve the...

The asymptotic behaviours for the solutions are also discussed. Through the concept of nonlinear self-adjointness, the conservation laws arising from the admitted point symmetries are listed. Keywords: time-fractional generalized porous media equation; symmetry group; conservation law; exact solutions MSC...
Magnetic flux is formally calculated as an integral, but the magnetic flux equation can also be calculated as the dot product of the magnitude of a magnetic field and an area, Φ=|B|Acos(θ), where Φ stands for the magnetic flux and θ is the angle between the magnetic field and the...
To drive an equation, a diffusion equation is considered for greater simplicity in just two dimensions. It is supposed that besides diffusion, there is a growth of the quantity of matter whose rate around a given point at the given time depends on the density already present, and an ...
