TL;DR: In this paper, the authors used direct Monte Carlo techniques to simulate drug delivery from compacts of complex composition, taking into consideration the special features of the in vitro dissolution environment, such as local interactions of the dissolving components, development of wall roughness at the solid-liquid interface, moving concentration boundary layer and mass transport by advection.

TL;DR: A program to simulate the ring spinning process was developed using MATLAB, which can predict yarn tension under given spinning conditions, and results were verified with experimental results obtained from ring spinning cotton and wool yarns.

TL;DR: This conjecture is that in cases where an agent-based simulation is affected by the temporal communication locality between agents, and there is complex agent–environment interaction, the two services will considerably improve the overall performance of a simulation.
