Transition of thermally induced flow in a square cavity using Spectral Method [PDF]
E3S Web of ConferencesThis study presents a novel mesh-free method for simulating natural convection in a square cavity filled with Newtonian fluid. The proposed algorithm integrates mesh-free Spectral methods with the Moving Collocation Element (MCOE) technique and employs a

A spectral multi-domain technique with application to generalized curvilinear coordinates [PDF]
Spectral collocation methods have proven to be efficient discretization schemes for many aerodynamic and fluid mechanic problems. The high order accuracy and resolution shown by these methods allows one to obtain engineering accuracy solutions on coarse ...

Assessing the impact of model biases on subseasonal forecast skill
Quarterly Journal of the Royal Meteorological Society, EarlyView.Relaxation experiments where the nudging was performed towards bias‐corrected integrations of the same model display significantly improved skill at weeks 3 and 4, particularly in the northern extratropics. This indicates that there is a large potential for improving dynamical subseasonal forecasting skill by improved treatment of model biases.

Determining the level of damping vibration in bridges and footbridges
Budownictwo i Architektura, 2016 While designing slim and slender structures such as cable-stayed, suspended and arch bridges and footbridges, data on the dynamic behavior of structure are required.

Quarterly Journal of the Royal Meteorological Society, EarlyView.Key Findings: An assimilation methodology is established for the Tomorrow.io microwave sounder (TMS) flying on CubeSats in sun‐synchronous and inclined orbits, and in all cloud scenes. The TMS has a significant impact on weather forecast lead times up to 3 days in the Tropics in a research‐quality numerical weather prediction setting, and yields water ...

, 2004 We present a Chebyshev collocation method for linear ODE and DDE problems. We first give a posteriori estimates for the accuracy of the approximate solution of a scalar ODE initial value problem. Examples of the success of the estimate are given.

Spectral Collocation Method for Generalized Abel’s Integral Equations
International Journal of Latest Technology in Engineering Management & Applied ScienceAbstract: This paper is devoted to the spectral collocation method using Jacobi polynomials for Generalized Abel’s integral equations (GAIEs). Jacobi polynomials are used to approximate the solution which reduces GAIEs to a system of algebraic equations. To show the theoretical accuracy of the proposed method, convergence analysis has been proved. Also,

Moisture inversions in the central Arctic: Product assessment and long‐wave radiative effect
Quarterly Journal of the Royal Meteorological Society, EarlyView.This study evaluates the integrated water vapour and the vertical distribution of water vapour of state‐of‐the‐art reanalyses, weather forecast models, and ground‐ and space‐based remote‐sensing products in the central Arctic. A particular focus lies on the representation of humidity inversions and the quantification of the long‐wave radiative effect ...

Accurate Chebyshev collocation solutions for the biharmonic eigenproblem on a rectangle
Journal of Numerical Analysis and Approximation Theory, 2017 We are concerned with accurate Chebyshev collocation (ChC) solutions to fourth order eigenvalue problems. We consider the 1D case as well as the 2D case.
