The FN method for solving atmospheric radiative-transfer problems is reviewed. In particular, a new choice of basis functions and collocation points that was found to perform very well for a class of problems characterized by highly anisotropic scattering (a standing challenge to the method) is reported, along with some improved computational techniques. # 1998 Elsevier Science Ltd.

one of the most important and brilliant aspects in each language is the collocation that finally add up to lexical coherence . coming together in semantics considers as one of the semantic relationships at lexical level that appears at all languages , and doesnt specialize for a certain language . mean while .the study of pre-islamic period poem about coming together is a significant affair . t...

This article studies the formation mission design problem for commercial aircraft in presence of uncertainties. Specifically, it considers uncertainties departure times and fuel burn savings trailing aircraft. Given several flights, consists arranging them or solo flights finding trajectories that minimize expected value DOC flights. The is formulated as an optimal control a stochastic switched...

− Just by adjusting the control points iteratively, progressive iterative approximation (PIA) presents an intuitive and straightforward scheme such that the resulting limit curve (surface) can interpolate the original data points. In order to obtain more flexibility, adjusting only a subset of the control points, a new method called local progressive iterative approximation (LPIA) has also been...

abstractthe present study explores the impact of corpus-based collocation instruction on intermediate iranian efl learners' writing ability. for this study, 84 iranian learners, studying english as a foreign language in bayan institute, iran, were selected and were randomly divided into two groups, experimental and control. conventional methods of writing instruction were taught to the control ...

This paper aims to compare three collocation point methods associated with the odd order stochastic response surface method (SRSM) in a systematical and quantitative way. The SRSM with the Hermite polynomial chaos is briefly introduced first. Then, three collocation point methods, namely the point method, the root method and the without origin method underlying the odd order SRSMs are highlight...

In this work, we analyse new robust spline approximation methods for mth order boundary value problems described by nonlinear ordinary diierential and integro-diierential equations with m linear boundary conditions. Our main aim is to introduce a cost-eeective alternative to the highly successful orthogonal col-location method, and to prove stability and convergence properties similar to the or...
