A mass transfer model of ethanol recovery by pervaporation with polydimethylsiloxane (PDMS) membrane was developed based on solution-diffusion theory considering concentration polarization. The water/polymer interaction parameter, ethanol/polymer interaction parameter, the limiting diffusivity of ethanol and ...
spherical precipitate/ A6630D Theory of diffusion and ionic conduction in solids A8130M PrecipitationIn this note the authors consider the isotropic diffusion controlled growth of one spherical precipitate in an infinite matrix in the approximation of the so-called `stationary solution', i.e. ...
It is shown that with the appropriate choice of the interaction potential, Debye's expression for the association rate constant becomes identical to that obtained using the radiation boundary condition if k is evaluated using Kramers' theory of diffusive barrier crossing. Finally, the competitive ...

Toward a theory of relaxation in correlated systems: diffusion in the phase space of a chaotic Hamiltonian*1 Relaxation in correlated systems such as interacting ions, entangled polymer chains or viscous liquids requires a time-dependent relaxation rate for a full... KL Ngai,RW Rendell - Journal...
We analyzed the convergence of approximate solutions to the accurate solution by utilizing the theory of module of continuity and a normed space of polynomials. We presented two main theorem related to feasibility of obtained estimate solutions and their convergence. We solved some numerical examples ...

Abstract: We argue that the theory and practice of diffusion-based generative models are currently unnecessarily convoluted and seek to remedy the situation by presenting a design space that clearly separates the concrete design choices. This lets us identify several changes to both the sampling and ...
