Numerical Modeling of an Optical Beam-Splitter by the Time-Domain Wavelet-Collocation Technique

open access: yes, 2002
Biorthogonal interpolating functions have been applied to electromagnetic field modeling through the wavelet-collocation technique in the time domain, yielding a versatile first-principle algorithm for the solution of time dependent Maxwell's equations ...

The difficult discussion on the deactivation of implantable cardioverter devices at the end of life: a systematic review

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 733-760, April 2025.
Abstract Implantable cardioverter defibrillators (ICDs) reliably prevent death due to life‐threatening arrhythmias; this may become less relevant in people with more severe heart failure who are reaching the end of life (EOL). This review aimed to explore the ICD deactivation process and identify ethical issues, especially around the initiation of ...

Stability Evaluation and Parametric Optimization of Coal‐Concrete Composite Bearing Systems Under Mine‐Water‐Induced Deterioration: Experiments and FEINN Analysis

open access: yesEnergy Science &Engineering, EarlyView.
Mine‐water immersion tests reveal pronounced coal weakening (vs. minor concrete degradation), identifying coal pillars as the stability‐limiting component in composite dams. A coupled FEINN framework quantifies extreme‐pressure stability and ranks multi‐parameter designs via a normalized multi‐indicator scheme, enabling optimized dam configuration for ...

An Orthogonal Collocation Technique for Rapid Thermal Processing System Discretization [PDF]

open access: yes, 1997
A model of a multiple heating zone Rapid Thermal Processing (RTP) system is developed to study wafer thermal dynamics during a processing cycle. The system is discretized with trial functions generated from the linearized wafer energy balance equation ...

Recovery Factor of Pure Helium Injection in Depleted Gas Reservoirs and Its Influencing Factors

open access: yesEnergy Science &Engineering, EarlyView.
This study employs compositional numerical simulation to systematically investigate the effects of injection rate, production rate, storage duration, and injection‐production scheme on pure helium recovery in depleted gas reservoirs. Low injection rates reduce viscous fingering while high production rates maximize near‐wellbore helium extraction ...

A novel node collocation technique in radial basis function collocation method applied to neutron diffusion equations

open access: yesAnnals of Nuclear Energy
A novel node collocation approach for the application of radial basis function meshless methods in neutron diffusion equations is presented in this paper. By introducing ghost nodes, the number and position of external nodes can be flexibly controlled to investigate their impact on the ill-conditioning of the coefficient matrix and the solution ...

The influence of baffle fairings on the acoustic performance of rectangular splitter silencers

open access: yes, 2005
A numerical model based on the finite element method is developed for a finite length, HVAC splitter silencer. The model includes an arbitrary number of bulk-reacting splitters separated from the airway by a thin perforated metal sheet and accommodates ...

The Learning Function of Evaluation: A Conceptual Framing

open access: yesNew Directions for Evaluation, EarlyView.
ABSTRACT In this article, we set out a conceptual overview of what we call learning in the evaluation ecosystem to depict the interplay between external influences, organizational and community factors, and learning levers (e.g. capacity building, systems thinking).
