Relief well pumping strategy for levee safety based on multivariate adaptive regression splines (MARS) and Non-dominated Sorting Genetic Algorithm II (NSGA-II) [PDF]

open access: yesScientific Reports
Relief wells’ performance gradually decreases over time due to physical and chemical clogging during the operations. Pumping at relief wells is an economic and feasible method to improve the performance of relief wells instead of installing new wells ...

Computational modeling of the Balitsky–Kovchegov equation and its numerical solution using hybrid B-spline collocation technique

open access: yesPartial Differential Equations in Applied Mathematics, 2022
The dynamics of high-energy scattering of hadrons are governed by Quantum Chromodynamics (QCD). In the parton model of QCD, scattering can be represented as a kind of reaction–diffusion process and consequently can be included in the category of the Fisher–Kolmogorov–Petrovsky–Piscounov (FKPP) equation.

Successive dynamic programming and subsequent spline optimization for smooth time optimal robot path tracking [PDF]

open access: yesMechanical Sciences, 2015
The time optimal path tracking for industrial robots regards the problem of generating trajectories that follow predefined end-effector (EE) paths in shortest time possible taking into account kinematic and dynamic constraints. The complicated tasks used

Approximation and geometric modeling with simplex B-splines associated with irregular triangles [PDF]

open access: yes, 1990
Bivariate quadratic simplical B-splines defined by their corresponding set of knots derived from a (suboptimal) constrained Delaunay triangulation of the domain are employed to obtain a C1-smooth surface.

B-Spline Finite Elements and their Efficiency in Solving Relativistic Mean Field Equations [PDF]

open access: yes, 1997
A finite element method using B-splines is presented and compared with a conventional finite element method of Lagrangian type. The efficiency of both methods has been investigated at the example of a coupled non-linear system of Dirac eigenvalue ...

Smoothing under Diffeomorphic Constraints with Homeomorphic Splines [PDF]

open access: yes, 2010
In this paper we introduce a new class of diffeomorphic smoothers based on general spline smoothing techniques and on the use of some tools that have been recently developed in the context of image warping to compute smooth diffeomorphisms.
