Asymptotic expansion for the trapezoidal Nyström method of linear Volterra—Fredholm equations

, 1994
Integral equations of mixed Volterra—Fredholm type arise in various physical and biological problems. In the present paper, we study the particular trapezoidal Nyström method and we obtain the asymptotic error expansion for the trapezoidal Nyström ...

Efficient Nyström-Based Unitary Single-Tone 2D DOA Estimation for URA Signals

Mathematics
We propose an efficient Nyström-based unitary subspace method for low-complexity two-dimensional (2D) direction-of-arrival (DOA) estimation in uniform rectangular array (URA) signal processing systems.

Clinical Heterogeneity Among Preschoolers Recruited as Infants Due to Elevated Likelihood of Autism: A Sibling Study

Scandinavian Journal of Psychology, EarlyView.
ABSTRACT Autism spectrum disorder (ASD), attention‐deficit/hyperactivity disorder (ADHD), and developmental language disorder (DLD) are neurodevelopmental conditions (NDCs) that share etiological factors and frequently co‐occur. Despite this, they have rarely been studied together—particularly in relation to functional outcomes.

Solving Boundary Value Problems Via the Nyström Method Using Spline Gauss Rules [PDF]

, 2022
We propose to use spline Gauss quadrature rules for solving boundary value problems (BVPs) using the Nyström method. When solving BVPs, one converts the corresponding partial differential equation inside a domain into the Fredholm integral equation of ...

Mathematical model of non-stationary temperature distribution in the metal body produced by induction heating process

EPJ Web of Conferences, 2016
An induction heating problem can be described by a parabolic differential equation. For this equation, specific Joule looses must be computed. It can be done by solving the Fredholm Integral Equation of the second kind for the eddy current of density ...

Physical Activity and Metabolic Alterations in Children and Adolescents Across Different Weight Groups: A Systematic Review

European Journal of Sport Science, Volume 26, Issue 7, July 2026.
ABSTRACT Inadequate physical activity (PA) and increased sedentary time are key drivers of cardiometabolic disorders related to being overweight, and metabolomics offers a promising novel approach to study their associations. The aim of this systematic review was to assess the evidence on metabolites associated with PA and/or sedentary time among ...

Exponentially-fitted Runge-Kutta-Nyström method for the numerical solution of initial-value problems with oscillating solutions

, 2002
A new approach for constructing efficient Runge-Kutta-Nyström methods is introduced in this paper. Based on this new approach a new exponentially-fitted Runge-Kutta-Nyström fourth-algebraic-order method is obtained for the numerical solution of initial ...

A five-stage singly diagonally implicit Runge-Kutta-Nyström method with reduced phase-lag [PDF]

, 2012
In this paper, a singly diagonally implicit Runge-Kutta-Nyström (RKN) method is constructed for solving second-order ordinary differential equations (ODE) with oscillatory solutions. The produced method is 5-stage, algebraic order five, and phase-lag (or

Servingness fractured and labored: A Latina's journey of negotiating belongingness under the guise of a Hispanic‐Serving Institution

Journal of Engineering Education, Volume 115, Issue 3, July 2026.
Abstract Background Students who perceive a mismatch between their disciplinary environment and their values, beliefs, and “fit” may lead them to consider other fields that better align with their ways of being and sense of belonging. Purpose The purpose of this study was to demonstrate the complexities of establishing a sense of belonging for a Latina
