Exponential integrators for parabolic problems with non-homogeneous boundary conditions

Carlos Arranz-Simón · Alexander Ostermann

Exponential Runge-Kutta methods are a well-established tool for the numerical integration of parabolic evolution equations. However, these schemes are typically developed under the assumption of homogeneous boundary conditions. In this paper, we extend classical convergence results to the case of non-homogeneous bounda...

A structuration approach to theorizing cybersecurity practice: The STARC model

Md Aktaruzzaman · Atif Ahmad · Sean B. Maynard

The problem: Cybersecurity practice runs simultaneously across analysts, teams, organizations, sectors, and regulators, co-evolves with adversaries, and increasingly blends human and algorithmic decision-making. The theories applied to it operate at single organizational levels and cannot explain why organizations with...

Temperature tuning of structural and mechanical properties of high-entropy carbides

Samuel GALLEGO PARRA · Miguel PAUL · Ernesto CHICARDI AUGUSTO · Andy FITCH · y 1 más

This proposal focuses on the study of High Entropy Carbides (HECs), a class of advanced ceramics with expected unique properties under high-temperature (HT) conditions. Six HECs with five equimolar transition metals from IVB (Ti, Zr, Hf) and VB (V, Nb, Ta) groups will be investigated using High-Resolution Powder X-Ray...

Following structural modifications of thermoresponsive hybrid hydrogels under temperature sweep or magnetic field by in-situ SAXS experiment

Lucie DIEVAL · Gilbert CHAHINE · Isabelle MORFIN · Claire HOTTON · y 2 más

The aim is to follow the microstructure of novel thermoresponsive hydrogels made of magnetic nanoparticles (akaganeite or nontronite) and Pluronic PF127 copolymer in order to develop cost-effective, and biocompatible hydrogels with multiple stimuli-responsive characteristics. Preliminary rheological experiments reveal...

Human Butyrylcholinesterase in complex with ligands

Sylvain ENGILBERGE · Antoine ROYANT · Xavier BRAZZOLOTTO

Human butyrylcholinesterase (BChE) has long been studied as a potential scavenger of nerve agents. Upon inhibition, the enzyme is covalently modified and the nerve agent is completely destroyed. Recently, human BChE has been the target of the development of new molecules for the treatment of the late stage of Alzheimer...

Neural network-assisted model predictive control for implicit balancing

Seyed Soroush Karimi Madahi · Kenneth Bruninx · Bert Claessens · Chris Develder

In Europe, balance responsible parties can deliberately take out-of-balance positions to support transmission system operators (TSOs) in maintaining grid stability and earn profit, a practice called implicit balancing. Model predictive control (MPC) is widely adopted as an effective approach for implicit balancing. The...

Bioaerosolization across 15 wastewater treatment plants: Decoupling between airborne and wastewater microbial concentrations

A. Ouradou · S. Khaddouma · E. Lachance · M. Veillette · y 2 más

Wastewater treatment plants (WWTPs) are recognized sources of bioaerosol emissions, however the roles of process configuration, wastewater quality, and environmental conditions in shaping airborne microbial loads remain poorly documented. This study aimed to relate airborne bacterial concentrations to WWTP configuratio...

Self-catalysed frontal polymerisation of structural composites through a gelated resin layer: Proof of concept and energy demand

Jeroen Staal · Lea Damiano · Noah Studer · Véronique Michaud

Frontal polymerisation (FP) has been demonstrated as a promising method for fast and energy-efficient composite manufacturing but suffers from limitations in fibre content (V f ), unless additional heaters, or a resin rich channel, are used to sustain the front. In this work, we propose a novel process configuration us...

CHRONOS

Benoît CORDONNIER

Many fundamental processes evolve over months and years, including 1) the strengthening of fault zones in the interseismic period between earthquakes, 2) the sequestration of carbon-bearing minerals in subsurface geologic reservoirs, 3) charge cycling in batteries, 4) the reactions between mixing magmas preceding volca...

A multimodal perspective on adaptive communication: Extending the hyper- and hypo-articulation theory
