Lecture 5: Diffusion Coefficient (Diffusivity)
inside spinodal is characterized by = < 0 since D A is always >0, then this means D A C <0 That is, if the original solution is cooled inside the spinodal, the chemical diffusion coefficient D A C is less than zero, i.e., a negative diffusion coefficient, as J A = - D A C · , it means the flux

A Guide to Debouncing
my.eng.utah.eduwandered in the hundreds of millivolts range for up to 8 msec. Then it suddenly snapped to a one. As the signal meandered up to near a volt the scope interpreted it as a one, but the analog’s continued uneasy rambles took it in and out of “one” territory. The MSO showered the screen with hash as it tried to interpret the data.
