Approaches to enthalpy approximation in numerical simulation of two-component alloy solidification
Computer Assisted Methods in Engineering and Science, 2023 The paper deals with the numerical modelling of solidification of two- component metal alloys. The numerical model was worked out using the enthalpy formulation of solidification and the finite element method.

Numerical approximation of the integral fractional Laplacian [PDF]
Numerische Mathematik, 2019 We propose a new nonconforming finite element algorithm to approximate the solution to the elliptic problem involving the fractional Laplacian. We first derive an integral representation of the bilinear form corresponding to the variational problem. The numerical approximation of the action of the corresponding stiffness matrix consists of three steps:

Numerical approximation of the spectrum of the curl operator [PDF]
Mathematics of Computation, 2013 For bounded, simply-connected domains, an eigenvalue problem for the curl operator with divergence-free eigensolutions is investigated. Two different weak formulations are presented and discretized by finite elements. The first one directly delivers the eigenvalues and eigensolutions of the original problem, but its discretization leads to a degenerate

Novel Approximations to the (Un)forced Pendulum–Cart System: Ansatz and KBM Methods
Mathematics, 2022 In the present investigation, some novel analytical approximations to both unforced and forced pendulum–cart system oscillators are obtained. In our investigation, two accurate and effective approaches, namely, the ansatz method with equilibrium point ...

Are approximate number system representations numerical?
Journal of Numerical Cognition, 2023 Previous research suggests that the Approximate Number System (ANS) allows people to approximate the cardinality of a set. This ability to discern numerical quantities may explain how meaning becomes associated with number symbols. However, recently it has been argued that ANS representations are not directly numerical, but rather are formed by ...

Central Nervous System Tumors Among Infants in Canada: A Report From CYP‐C
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Central nervous system (CNS) tumors in infants are rare, pose unique clinical challenges, and lack large‐scale evidence‐based data to guide management. This study seeks to describe CNS tumors in Canadian infants and to compare their outcomes with those of older children.
