On spherical averages of radial basis functions [PDF]
, 2008 A radial basis function (RBF) has the general form $$s(x)=\sum_{k=1}^{n}a_{k}\phi(x-b_{k}),\quad x\in\mathbb{R}^{d},$$ where the coefficients a 1,…,a n are real numbers, the points, or centres, b 1,…,b n lie in ℝ d , and φ:ℝ d →ℝ is a radially symmetric

CT&F Ciencia, Tecnología & Futuro, 2006 Because of fluvial deposition or faulting, many reservoirs around the world may possess a long and narrow geometry in which linear flow is expected to take place once radial flow vanishes, if existed.

CT&F Ciencia, Tecnología & Futuro, 2009 It is expected for naturally occurring formations that the transition period of flow from fissures to matrix takes place during the radial flow regime. However, depending upon the value of the interporosity flow parameter, this transition period can show

ESTRUCTURAS DE RECIRCULACIÓN EN UN CONTENEDOR CILÍNDRICO
Anales (Asociación Física Argentina), 2013 El campo de velocidades de un filamento vorticoso (o vórtice) se puede modelizar considerando los mecanismos de difusión de la vorticidad y conservación del momento angular. Según este esquema el flujo producido por la componente axial de la velocidad es

Radial evolution of cross helicity in high-latitude solar wind [PDF]
, 2005 We employ a turbulence transport theory to explain the high-latitude radial evolution of cross helicity, or Alfvénicity, observed by the Ulysses spacecraft.

Practical identification of NARMAX models using radial basis functions [PDF]
, 1990 A wide class of discrete time non-linear systems can be represented by the non-linear autoregressive moving average model with exogenous inputs or NARMAX model. This paper develops a practical algorithm for identifying NARMAX models based on radial basis
