This is the Second Year Progress Report for the “Algorithms for Packing and Scheduling” Ph.D. project. In this report, we give the aims of the project, a summary of the current results obtained, we address the questions raised in the Postgraduate Workshop, and we conclude with possible future work and a timetabled research plan. The project is concerned with the study, design, and analysis, of ...

We investigate dynamical heterogeneities in the collective relaxation of a concentrated microgel system, for which the packing fraction can be conveniently varied by changing the temperature. The packing fraction-dependent mechanical properties are characterized by a fluid-solid transition, where the system properties switch from a viscous to an elastic low-frequency behaviour. Approaching this...

Particles in a packing will rotate when the is deformed. We find that rotations display diffusive dynamics set by particle friction and fraction. Rotations are spatially anticorrelated directly indicative of system pressure.

Due to the generality and flexibility of Monte Carlo method in geometric modeling, plays an important role accurate simulation random media. At present, rand om sequential addition (RSA) distinct element (DEM) are more mature explicit modeling methods. The former approach has problem upper limit packing fraction, which is suitable for stochastic geometry with lower filling rate. DEM can fill me...

This paper aims to numerically predict the capacitance of electric double layer capacitors (EDLCs) made of mesoporous electrodes consisting of closely packed monodispersed mesoporous carbon spheres in (C2H5)4NBF4/propylene carbonate electrolyte. The model faithfully accounts for the electrode packing morphology and the dependency of electrolyte dielectric permittivity on local electric field. T...

The local structure of disordered jammed packings of monodisperse spheres without friction, generated by the Lubachevsky-Stillinger algorithm, is studied for packing fractions above and below 64%. The structural similarity of the particle environments to fcc or hcp crystalline packings (local crystallinity) is quantified by order metrics based on rank-four Minkowski tensors. We find a critical ...

Recently the conventional notion of random close packing has been supplanted by the more appropriate concept of the maximally random jammed (MRJ) state. This inevitably leads to the necessity of distinguishing the MRJ state among the entire collection of jammed packings. While the ideal method of addressing this question would be to enumerate and classify all possible jammed hard-sphere configu...
