• The Wigner Distribution of Gaussian Weakly Harmonizable Stochastic Processes

  سند علمی۲۰۰۵Patrik Wahlberg, P. Wahlberg

  The paper treats theWigner distribution of scalar-valued stochastic processes defined on R. We show that if the process is Gaussian and weakly harmonizable then a stochastic Wigner distribution is well defined. The special case of stationary processes is studied, in which case th

• On Weakly Measurable Stochastic Processes and Absolutely Summing Operators

  سند علمی۲۰۰۶V. Marraffa

  A linear and continuous operator between Banach spaces is said to be absolutely summing if it maps unconditionally convergent series into absolutely convergent series. Moreover, it improves properties of stochastic processes. Indeed, N.Ghoussoub in [7] proved that an operator is

• A representation theorem for stochastic processes with separable covariance functions, and its implications for emulation

  سند علمی۲۰۱۱Jonathan Rougier

  Many applications require stochastic processes specified on twoor higherdimensional domains; spatial or spatial-temporal modelling, for example. In these applications it is attractive, for conceptual simplicity and computational tractability, to propose a covariance function that

• Optimal Representations of Sparse Stochastic Processes with Applications in Image Processing

  سند علمی۲۰۱۷Pedram Pad, Pascal Frossard

  We establish in the world of stochastic processes a theoretical relation between sparsity and wavelets. The underlying principle is to treat stochastic processes as generalized functions, which facilitates the study of their properties in a transform domain. We focus on symmetric

• Persistence of a continuous stochastic process with discrete-time sampling.

  سند علمی۲۰۰۱Physical review. E, Statistical, nonlinear, and soft matter physicsS N Majumdar, A J Bray, G C Ehrhardt

  We introduce the concept of "discrete-time persistence," which deals with zero-crossings of a continuous stochastic process, X(T), measured at discrete times, T=n Delta T. For a Gaussian Markov process with relaxation rate mu, we show that the persistence (no crossing) probabilit
