A Biophysical Approach to the Design of Networks of Communication Systems

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT Inspired by the growth dynamics of the protist Physarum polycephalum, we employ a formalism that describes adaptive, incompressible Hagen‐Poiseuille flows on channel networks to identify graphs connecting different nodes within Euclidean space. These graphs are either suboptimal or optimal relative to their length.

Interaction Between Vortex‐Induced Vibrations and Base Vibrations in Piezoelectric Harvesters

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In the present era, powering sensors using green energy is a significant challenge. One promising solution for the power supply of small sensors relies on piezoelectric energy harvesters excited by vortex‐induced vibrations (VIVs) generated by wind.

Numerical Investigation of Bored Tunnelling Effects on Pile‐Supported Superstructures

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Tunnelling in urban environments can significantly affect existing buried structures such as pile foundations. However, the current understanding of how tunnelling‐induced ground movements influence the stability and serviceability of piles remains limited. This knowledge gap presents potential risks that must be addressed during tunnel design
