An Overview of the Probability Density Evolution Method in Stochastic MechanicsJianbing Chen
Ph.D., Associate Professor, School of Civil Engineering, Tongji University
Visiting Scholar, USC.AbstractStochastic mechanics has gained increasing interests. In the past decades, extensive investigations have been made in the discipline, leading to a variety of approaches. The presentation will deal with a newly developed probability density evolution method, which starts from revisiting the principle of preservation of probability. Based on the random event description (Lagrange description), a partial differential equation governing evolution of the one- or any arbitrary- dimensional joint probability density function could be set up. This equation could be conveniently numerically solved through combining the deterministic dynamic analysis and the finite difference method. The probability density evolution method could be applied to static/dynamic stochastic response analysis of linear/nonlinear structures, dynamic reliability evaluation and system reliability evaluation. Some key problems need further investigations are discussed.Location: Kaprielian Hall (KAP) - 415

Photodetection and Locality

SPEAKER: Prof. Ian Percival, University of LondonABSTRACT: Locality follows from classical relativistic dynamics. Nonlocality
follows from quantum theory with ideal quantum measurements, but
has never been demonstrated experimentally without a further
assumption. For the experiment of Zeilinger, Weihs and their collaborators
(ZW), this was 'fair sampling'. We investigate this assumption and
conclude that further experiments and theory are needed.Joint work with Barry Garraway.BIO: Ian Percival is Professor of Physics at Queen Mary, University of
London. He has worked on theoretical atomic physics, chaos theory, quantum state diffusion, and his main interest at present is in theoretical and experimental aspects of Bell inequalities.Host: Prof. Todd Brun, tbrun@usc.eduLocation: Seaver Science Library (SSL) - 150
