Sliding Mode Control in Aerospace Applications: A Survey

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Insights From the Alphasat Aldo Paraboni Experiment at Tito Scalo and Spino d'Adda: Characterizing Scintillation and Rain Attenuation at Ka‐ and Q‐Band Frequencies

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT We present experimental results on the relationship between rain attenuation and simultaneous scintillation during rain events, based on beacon signal measurements at 19.7 (Ka‐band) and 39.4 GHz (Q‐band) from the geosynchronous Alphasat satellite (25° E), received at two Italian ground stations, Spino d'Adda (42.1° slant path) and Tito Scalo ...

From Innovation to Sustainability: Integrating Fintech, Green Trade and Knowledge Systems for Circular Growth in Sub‐Saharan Africa

open access: yesSustainable Development, EarlyView.
ABSTRACT The transition toward circular and sustainable growth remains a major challenge in Sub‐Saharan Africa (SSA), where resource constraints, limited recycling capacity, and infrastructure deficits constrain environmental performance. Drawing on circular economy and innovation systems perspectives, this study examines how financial technology ...

AI Vibrancy and Renewable Energy Consumption: A Cross‐Country Analysis

open access: yesSustainable Development, EarlyView.
ABSTRACT This study examines the association between artificial intelligence vibrancy and renewable energy consumption across 36 countries from 2017 to 2023. Using a reduced‐form panel framework with Driscoll–Kraay standard errors, the results show that income per capita and government effectiveness are the dominant drivers of renewable energy ...
