JAWRA Journal of the American Water Resources Association, Volume 61, Issue 3, June 2025.ABSTRACT Farm ponds are a common feature of agricultural landscapes for irrigation of crops. Yet small water bodies have been ignored as reservoirs and carbon balance features despite their ubiquity in the global landscape. These ponds contain surface water from precipitation and runoff, but in South Georgia, USA, groundwater supplementation is ...

Bivariate High‐Accuracy Hermite‐Type Multiquadric Quasi‐Interpolation Operators
Journal of Mathematics, Volume 2025, Issue 1, 2025.In this paper, a kind of Hermite‐type multiquadric quasi‐interpolation operator is constructed by combining an extended univariate multiquadric quasi‐interpolation operator with a bivariate Hermite interpolation polynomial. Some error bounds in terms of the modulus of continuity of high order and Peano representations for the error are given. Numerical

Journal of Mathematics, Volume 2025, Issue 1, 2025.We aim to introduce a numerical method to solve a system of two‐dimensional nonlinear integral equations of Volterra–Fredholm type with the second kind on nonrectangular domains. The method estimates the solutions of the system by a discrete collocation method based on radial basis functions constructed on scattered points.

Anisotropic Radial Basis Function Methods for Continental Size Ice Sheet Simulations
, 2017 In this paper we develop and implement anisotropic radial basis function methods for simulating the dynamics of ice sheets and glaciers. We test the methods on two problems: the well-known benchmark ISMIP-HOM B that corresponds to a glacier size ice and ...

Remeshing in the finite cell method for different types of geometry descriptions
Proceedings in Applied Mathematics and Mechanics, Volume 24, Issue 4, December 2024.Abstract The numerical structural analysis of problems with complex geometries can be challenging, especially if standard finite elements are used. In contrast, immersed methods, such as the finite cell method, relieve the mesh generation such that simply shaped elements/cells can be used.

A shape optimization pipeline for marine propellers by means of reduced order modeling techniques
International Journal for Numerical Methods in Engineering, Volume 125, Issue 7, 15 April 2024.Abstract In this article, we propose a shape optimization pipeline for propeller blades, applied to naval applications. The geometrical features of a blade are exploited to parametrize it, allowing to obtain deformed blades by perturbating their parameters. The optimization is performed using a genetic algorithm that exploits the computational speed‐up
