The Discretization‐Corrected Particle Strength Method for the Barotropic Vorticity Equations

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
Numerical solution for the barotropic vorticity equation in complex geometry using the meshless point collocation method. The spatial domain is represented by a set of nodes. The collocation method numerically solves the strong form governing equations.

Comparison of two infiltration equations with three‐terms expansions consistent with the approach of Philip theory

open access: yesIrrigation and Drainage, EarlyView.
Abstract In this study, the approximate three‐term (3 T) one‐dimensional (1D) vertical infiltration equation by Valiantzas (3 T‐V) and the 3 T approximate infiltration equation of the quasi‐exact implicit (QEI) Haverkamp equation (3T‐R) by Rahmati et al. for both direct and inverse modelling of water infiltration into soils were evaluated.

Analysis of image formation in optical palpation

open access: yesJournal of Biophotonics, EarlyView.
Optical palpation is an emerging elastography technique that generates images of mechanical stress at the tissue surface, with applications in intraoperative cancer detection. Image formation is simulated using finite element analysis and validated with experiments on silicone phantoms, providing an analysis of trends in detectability, feature ...

The Parallel Tiled WZ Factorization Algorithm for Multicore Architectures

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2019
The aim of this paper is to investigate dense linear algebra algorithms on shared memory multicore architectures. The design and implementation of a parallel tiled WZ factorization algorithm which can fully exploit such architectures are presented. Three

Strong External Difference Families and Classification of α $\alpha $‐Valuations

open access: yesJournal of Combinatorial Designs, EarlyView.
ABSTRACT One method of constructing (a2+1,2,a,1) $({a}^{2}+1,2,a,1)$‐SEDFs (i.e., strong external difference families) in Za2+1 ${{\mathbb{Z}}}_{{a}^{2}+1}$ makes use of α $\alpha $‐valuations of complete bipartite graphs Ka,a ${K}_{a,a}$. We explore this approach and we provide a classification theorem which shows that all such α $\alpha $‐valuations ...

Enumeration and Construction of Row‐Column Designs

open access: yesJournal of Combinatorial Designs, EarlyView.
ABSTRACT We computationally completely enumerate a number of types of row‐column designs up to isotopism, including double, sesqui, and triple arrays as known from the literature, and two newly introduced types that we call mono arrays and AO‐arrays. We calculate autotopism group sizes for the designs we generate.
