Webwhich is Fourier’s law of heat conduction for a one-dimensional steady system.. Thermal conductivity k is a thermophysical property and has the units W/(m·K). If the thermal conductivity does not change from point to point within the medium, then medium is named as a homogenous, and heterogeneous if there is a variation of the thermal conductivity.

Let's say that f ( t) and g ( t) have units of, say, meters and Hertz, respectively; and that t and τ are both time. What units does the convolution ( f ∗ g) ( t) have?

Unless you normalize it by something with a unit, like in 1 T ∫ e − 2 π j ⋅ x ( t) d t where to "average" over some period or time span T (in time units), and then the results would have the same units as x ( t) again.

Thus, using the chain rule reveals that the derivative in the direction tangent to the space curve is $$\frac{dT}{ds}=\nabla T\cdot \frac{d\vec r}{ds}$$ jordan malita rugby highlights
