Recent approximation algorithms (e.g., CounterStacks, SHARDS and AET) make lightweight, continuouslyupdated miss ratio curves (MRCs) practical for online modeling and control of LRU caches. For more complex cache-replacement policies, scaled-down simulation, introduced with SHARDS, offers a general method for emulating a given cache size by using a miniature cache processing a small spatially-h...

In France, recent mathematics curricula reinforce the teaching of statistics and probability. They recommend starting with an experimental approach introducing the observation of sampling fluctuations and the construction of random experiment simulations in order to prepare students for theory. This approach raises the problem of the didactical practice of random experiment modeling and simulat...

The research work outlined in the present note highlights the essential role played by the simulation procedures implemented by us on CINECA supercomputers to complement the mathematical investigations carried within our group over the past several years. The ultimate target of our research is the understanding of certain crucial features of the information processing and transmission by single...

During the last years, we have developed nonadiabatic excited state dynamics methods based on Trajectory Surface Hopping/Linear Response Time-Dependent Density Functional Theory (TSH/LRTDDFT) and real time propagation TDDFT (PT-TDDFT) based Ehrenfest dynamics and have combined them with mixed quantum mechanical/ molecular mechanical (QM/MM) simulations to study nonadiabatic processes in complex...

discrete element method (dem) is extensively used for mathematical modeling and simulating the behavior of discrete discs and discrete spheres in two and three dimensional space, respectively. prediction of particles flow regime, power draw and kinetic energy for a laboratory or an industrial mill is possible by dem simulation. in this article, a new approach was used to assess the main paramet...

background: the characteristics of secondary neutrons in a high energy radiation therapy room were studied using the mcnpx monte carlo (mc) code. materials and methods: two mc models including a model with full description of head components and a simplified model used in previous studies were implemented for mc simulations. results: results showed 4-53% difference between full and with the sim...
