Exploration of Half‐Cycle Length of Converging Circular Wavy Duct with Diverging‐Outlet: Turbulent Water Dynamics

open access: yesAdvanced Theory and Simulations, EarlyView.
Increasing half‐cycles intensifies turbulence due to enhanced vortex interactions and flow separation at the diverged‐outlets. Longer wavy ducts are shown to increase flow acceleration, resulting in greater output velocities and more turbulent‐kinetic‐energy production. Wave‐period plays a crucial role in determining turbulent intensity, with amplitude

Post‐earthquake estimates of different ground motion intensity measures for the 2012 Emilia earthquake

open access: yesEarthquake Engineering &Structural Dynamics, Volume 52, Issue 1, Page 183-203, January 2023., 2023
Abstract Estimates of the earthquake ground motion intensity over a geographical area have multiple uses, that is, emergency management, civil protection and seismic fragility assessment. In particular, with reference to fragility assessment, it is of interest to have estimates of the values of different ground‐motion intensity measures in order to ...

Blow-Up and Global Existence Analysis for the Viscoelastic Wave Equation with a Frictional and a Kelvin-Voigt Damping

open access: yesAdvances in Mathematical Physics, 2018
We are concerned in this paper with the initial boundary value problem for a quasilinear viscoelastic wave equation which is subject to a nonlinear action, to a nonlinear frictional damping, and to a Kelvin-Voigt damping, simultaneously.

Behaviors of the energy of solutions of two coupled wave equations with nonlinear damping on a compact manifold with boundary [PDF]

open access: yesarXiv, 2017
In this paper we study the behaviors of the the energy of solutions of coupled wave equations on a compact manifold with boundary in the case of indirect nonlinear damping . Only one of the two equations is directly damped by a localized nonlinear damping term.

FMint: Bridging Human Designed and Data Pretrained Models for Differential Equation Foundation Model for Dynamical Simulation

open access: yesAdvanced Theory and Simulations, EarlyView.
FMint is introduced as a multi‐modal foundation model that integrates human‐designed solvers and data‐driven methods for fast, accurate simulation of dynamical systems. FMint leverages in‐context learning within a transformer‐based framework to refine coarse numerical solutions.

Seismic fragility models for base‐isolated unreinforced masonry buildings with fibre‐reinforced elastomeric isolators

open access: yesEarthquake Engineering &Structural Dynamics, Volume 52, Issue 2, Page 308-334, February 2023., 2023
Abstract Unreinforced masonry (URM) buildings are highly vulnerable to seismic ground motion, calling for quantitative risk assessment and mitigation programmes in different earthquake‐prone countries to reduce future losses. Despite the effectiveness of base isolation technology in reducing seismic response of buildings, the high costs of conventional

Controlled nonlinear magnetic damping in spin-Hall nano-devices

open access: yesNature Communications, 2019
Nonlinear damping enhancement imposes strict limitations on the operation and efficiency of magnetic nano-devices. Here the authors show that nonlinear damping can be controlled by the ellipticity of magnetization precession, which provides a route for ...
