An automatic tree search algorithm for the Tisserand graph

open access: yesAlexandria Engineering Journal, 2021
The Tisserand graph (TG) is a graphical tool commonly employed in the preliminary design of gravity-assisted trajectories. The TG is a two-dimensional map showing essential orbital information regarding the Keplerian orbits resulting from the close ...

Management of invasive alien plants in forests: A global perspective

open access: yesJournal of Applied Ecology, Volume 63, Issue 7, July 2026.
This review exposes urgent and critical knowledge gaps in forest IAP management, which need addressing to meet global targets for biodiversity and forest health. These gaps include highly uneven global research effort, narrow species focus, limited method replication, overlooked seasonal effects, and inconsistent cost reporting.

Deep Neural Networks for the Estimation of Masonry Structures Failures under Rockfalls

open access: yesGeosciences, 2023
Although the principal aim of the rockfall management is to prevent rock boulders from reaching the buildings instead of the buildings resisting the boulder impacts, there usually exists a residual risk that has to be assessed, even when structural ...

Seeing herbaria in a new light: leaf reflectance spectroscopy unlocks trait and classification modeling in plant biodiversity collections

open access: yesNew Phytologist, Volume 251, Issue 2, Page 811-829, July 2026.
Summary Reflectance spectroscopy is a rapid method for estimating traits and discriminating species. Spectral libraries from herbarium specimens represent an untapped resource for generating broad phenomic datasets across space, time, and taxa. We conducted a proof‐of‐concept study using trait data and spectra from herbarium specimens up to 179 yr old,

Digital twin adoption in port authorities: a structured framework for use case assessment

open access: yesJournal of Shipping and Trade
Digital Twin (DT) technology has considerable potential to transform port operations, yet high implementation costs and uncertain benefits have constrained its adoption.

Adaptive Warning Thresholds for Dam Safety: A KDE-Based Approach

open access: yesInfrastructures
Dams are critical infrastructures that provide essential services such as water supply, hydroelectric power generation, and flood control. As many dams age, the risk of structural failure increases, making safety assurance more urgent than ever ...

Reduced order models for thermally coupled low Mach flows

open access: yesAdvanced Modeling and Simulation in Engineering Sciences, 2018
In this paper we present a collection of techniques used to formulate a projection-based reduced order model (ROM) for zero Mach limit thermally coupled Navier–Stokes equations. The formulation derives from a standard proper orthogonal decomposition (POD)
