Experimental investigation and ReaxFF simulation on pore structure evolution mechanism during coalification of coal macromolecules in different ranks

Scientific Reports
This analysis revealed the alterations in the pore structure of large organic molecules in coal during the process of coal pyrolysis. Nine models of macromolecular structures in coals, representing distinct coal ranks, have been built.

Constructive Alignment in Process Mining

Abstract Constructive alignment is a well-established concept in education that helps teachers design courses and modules. When we look at constructive alignment as engineers, we can interpret it as a set of axioms for setting up successful process mining projects. While in process mining we have several useful methodologies (e.g.

On the mining of artful processes.

, 2013
Artful processes are those processes in which the experience, intuition, and knowledge of the actors are the key factors in determining the decision making. These knowledge-intensive processes are typically carried out by the “knowledge workers”, such as professors, managers, researchers.
