Analytical and Numerical Models of Sandwich Panel taking into Account Wrinkling Phenomenon

BLASZCZUK, Jolanta; POZORSKI, Zbigniew - In: Romanian Statistical Review Supplement 60 (2012) 4, pp. 238-244

The problem of local instability of the compressed facing of a sandwich panel is discussed in this paper. Proper estimation of wrinkling stress has become a challenging issue because of a strong tendency to optimize technical parameters and costs. The aim of the study is numerical and analytical...

Molecular phase space transport in water: Non-stationary random walk model

Nerukh, Dmitry; Ryabov, Vladimir; Taiji, Makoto - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 22, pp. 4719-4726

Molecular transport in phase space is crucial for chemical reactions because it defines how pre-reactive molecular configurations are found during the time evolution of the system. Using Molecular Dynamics (MD) simulated atomistic trajectories we test the assumption of the normal diffusion in...

Complexity analysis of the stock market

Park, Joongwoo Brian; Won Lee, Jeong; Yang, Jae-Suk; … - In: Physica A: Statistical Mechanics and its Applications 379 (2007) 1, pp. 179-187

We study the complexity of the stock market by constructing ε-machines of Standard and Poor's 500 index from February 1983 to April 2006 and by measuring the statistical complexities. It is found that both the statistical complexity and the number of causal states of constructed ε-machines...

Mechanisms of Emergent Computation in Cellular Automata

Hordijk, Wim; Crutchfield, James P.; Mitchell, Melanie - Santa Fe Institute - 1998

We introduce a class of embedded-particle models for describing the emergent computational strategies observed in cellular automata (CAs) that were evolved for performing certain computational tasks. The models are evaluated by comparing their estimated performances with the actual performances...
