Desenvolupament de models per elements finits de barreres per a tests d'impactes de vehicles

, 2020
Per tal d’avaluar el nivell de seguretat que tenen els vehicles i realitzar la seva homologació, es realitzen un seguit d’assajos d’impactes regulats que pretenen replicar les condicions en diferents escenaris d’accidents de trànsit. Per la realització d’

A New Incremental Cycling Cognitive‐Motor Dual‐Task Test to Assess Simultaneous Sustained Attention and Neuromuscular Fatigue in Trained Athletes

Scandinavian Journal of Medicine &Science in Sports, Volume 35, Issue 9, September 2025.
ABSTRACT Cognitive performance during cognitive‐motor dual‐task (CMDT) varies with exercise intensity. According to the inverted‐U theory, low‐to‐moderate intensity enhances cognition, but this remains unexplored in trained individuals who may better sustain cognitive performance at high intensities due to improved prefrontal cortex (PFC) homeostasis ...

Adaptive finite element methods

Acta Numerica
This is a survey of the theory of adaptive finite element methods (AFEMs), which are fundamental to modern computational science and engineering but whose mathematical assessment is a formidable challenge. We present a self-contained and up-to-date discussion of AFEMs for linear second-order elliptic PDEs and dimension d > 1, with emphasis on ...

Verbesserter Stofftransport und Ladungstransfer in COF‐basierten Photokatalysatoren mit dreidimensional geordneten Makroporen für die Benzylaminoxidation und Wasserstoffentwicklung

Angewandte Chemie, Volume 137, Issue 34, August 18, 2025.
Ein einstufiges, selbstopferndes Templating ermöglicht die Synthese von 3DOM‐COFs mit geordneten Makroporen. In Kombination mit ZnCdS katalysiert das daraus resultierende S‐Schema‐Heterojunktion effizient die Oxidation von Benzylamin und die H₂‐Entwicklung.

Modelització del deflectòmetre d'impacte amb el mètode dels elements finits i les partícules [PDF]

, 2011
El deflectòmetre d’impacte segurament és l’aparell més utilitzat per realitzar assaigs no destructius dels ferms. Els enginyers utilitzen el deflectròmetre d’impacte per estimar els mòduls elàstics de les diferents capes que conformen el ferm assumint ...

The tempered finite element method

Journal of Computational Physics
In this paper, we propose a new approach -- the Tempered Finite Element Method (TFEM) -- that extends the Finite Element Method (FEM) to classes of meshes that include zero-measure or nearly degenerate elements for which standard FEM approaches do not allow convergence.

Arithmetical pluralism and the objectivity of syntax

Noûs, Volume 59, Issue 2, Page 372-391, June 2025.
Abstract Arithmetical pluralism is the view that there is not one true arithmetic but rather many apparently conflicting arithmetical theories, each true in its own language. While pluralism has recently attracted considerable interest, it has also faced significant criticism.

Fluorescent Probe for δ‐Cyclodextrin Enables Guest Encapsulation Studies via an Indicator Displacement Assay

ChemistryEurope, Volume 3, Issue 3, May 2025.
A molecular probe that partially unfolds and exhibits fluorescence enhancement upon binding to δ‐cyclodextrin (δ‐CD) is presented. Its implementation in a fluorescence indicator displacement assay to test the binding of various guest to δ‐CD is demonstrated.
