We propose an efficient Monte Carlo algorithm for the off-lattice simulation of dense hard sphere polymer melts using cluster moves, called event chains, which allow for a rejection-free treatment of the excluded volume. Event chains also allow for an efficient preparation of initial configurations in polymer melts. We parallelize the event chain Monte Carlo algorithm to further increase simula...

abstract background: accurate methods of radiation therapy dose calculation. there are different monte carlo codesfor simulation of photons, electrons and the coupled transport of electrons and photons. mcnpis a general purpose monte carlo code that can be used for electron, photon and coupledphoton-electron transport.monte carlo simulation of radiation transport is considered to be one of the ...

Introduction: Monte Carlo calculation method is considered to be the most accurate method for dose calculation in radiotherapy. The purpose of this research is comparison between 6 MV Primus LINAC simulation output with commissioning data using EGSnrc and build a Monte Carlo geometry of 6 MV Primus LINAC as realistically as possible. The BEAMnrc and DOSXYZnrc (EGSnrc package) M...

of the Dissertation Performance Evaluation Under Modeling Uncertainty: A Unified Approach Using Spherically Invariant Random Process by Cheng-An Yang Doctor of Philosophy in Electrical Engineering University of California, Los Angeles, 2015 Professor Kung Yao, Chair In this dissertation, we considered the exceedingly general spherically invariant random process (SIRP) as a unifying framework fo...

The performance of a CMOS circuit depends heavily on its transistor sizes. We have tested a standard optimizer, a Monte Carlo scheme and a method based on Genetic Algorithms combined with very accurate SPICE simulations to automatically optimize transistor sizes of three diierent digital CMOS circuits. While the standard optimizer and the Monte Carlo scheme are advantageous for small circuits, ...

we compare two approaches for a markovian model in flexible manufacturing systems (fmss) using monte carlo simulation. the model which is a development of fazlollahtabar and saidi-mehrabad (2013), considers two features of automated flexible manufacturing systems equipped with automated guided vehicle (agv) namely, the reliability of machines and the reliability of agvs in a multiple agv jobsho...

background: iodine brachytherapy sources with low photon energies have been widely used in treating cancerous tumors. dosimetric parameters of brachytherapy sources should be determined according to aapm tg-43u1 recommendations before clinical use. monte carlo codes are reliable tools in calculation of these parameters for brachytherapy sources. materials and methods: dosimetric parameters (dos...
