    This special issue of CiSE highlights various aspects of and outstanding problems in stochastic modeling of complex systems. The techniques covered include stochastic spectral methods, the information-theoretic approach, and sensitivity analysis for uncertainty quantification. Two application articles-one in the field of ecology and the other in the field of manufacturing design-emphasize the dive... View full abstract»

    Predictive modeling's effectiveness is hindered by inherent uncertainties in the input parameters. Sensitivity and uncertainty analysis quantify these uncertainties and identify the relationships between input and output variations, leading to the construction of a more accurate model. This survey introduces the application, implementation, and underlying principles of sensitivity and uncertainty ... View full abstract»

  • An Information-Theoretic Approach to Stochastic Materials Modeling

    Publication Year: 2007, Page(s):30 - 39

    An approach derived from information-theoretic principles can help researchers build stochastic microstructural models. This approach involves extracting topological information from microstructural samples and using this information to build a stochastic model. To generate huge databases of stochastic material models, the authors thus propose using an information-learning algorithm to train a net... View full abstract»

    A supply chain is a network of facilities and activities that procure, produce, and distribute goods to customers. Many uncertainties within a supply chain can substantially affect its performance. The author discusses how to model these uncertainties in integrated supply-chain design models and studies their impacts on optimal supply-chain decisions View full abstract»

    Quantum computing, say its champions, promises prodigious power. its basic currency, the qubit, exists in an on/off limbo until it's read out, so if you could operate on kqubits, a potentially vast space of 2 k values opens up for computation. the fundamental operation on qubits is a rotation. Combine the rotations, and you have logic gates. Combine the logic gates, and you have algorit... View full abstract»
