Parsimonious Var Models For Air Pollution Dynamic Analysis

Abstract

Abstract:We discuss a framework to obtain temporal predictions for an evolving spatial field regularly sampled in time at arbitrary spatial locations. Difficulties caused by large data sets and the modelling of complicated spatio-temporal interactions limit the effectiveness of traditional space-time statistical models. In this study, we propose the use of a flexible approach to deal with large and small time-scale variability of the observed data. The temporal model is applied with respect to both the observed data domain and the common component domain, to achieve a dimensionality reduction.

A Note on the Numerical Solution for Fredholm Integral Equation of the Second Kind with Cauchy kernel

“…The integral equations with Cauchy kernel have been widely used in solving problems associated with aerodynamic, hydrodynamic and elasticity (Lifanov, 1996;Ladopoulos, 2000;Abdou and Naser, 2003;Mohankumar and Natarajan, 2008;Lara and Mariagrazia, 2005;Kasozi and Paulsen, 2005a;Kasozi and Paulsen, 2005b;Ganji et al, 2008;Thukral, 2005).…”
