Application of Cooperative Control of Discrete‐Time Nonlinear Multi‐Agent Systems Based on Extended Kalman Unknown Input Observer

Vector: The Journal of Engineering, Volume 2027, Issue 1, January/December 2027.
This study is concerned with the application of consensus control to a class of discrete‐time nonlinear multi‐agent systems with unknown inputs and additive noise. The aim is to design an extended Kalman unknown input observer (EKUIO) such that the state vector of a discrete‐time nonlinear system can be estimated, additive noise can be mitigated, and ...

Estimation of Error Margin in the Quantification of Large Wood Volumes in River From In Situ and UAV Measurements

Earth Surface Processes and Landforms, Volume 51, Issue 10, October 2026.
Large wood (LW) plays a key role in river dynamics and biodiversity, but quantifying its volume and budget remains challenging. This study compared in situ and UAV‐based measurements of LW jams in two Gaspé Peninsula rivers (Québec, Canada), highlighting strong variability mainly due to operator bias. A new methodology reduced this variability, leading

Laser‐Induced Graphene‐Based Resistive Leaf Wetness Sensors for Pesticide Spray Deposition

Global Challenges, Volume 10, Issue 10, October 2026.
A laser‐induced graphene leaf wetness sensor is fabricated by CO2 laser‐patterning interdigitated electrodes on flexible polyimide and adding silver‐paste contacts through a shadow mask. Calibration with multiple pesticide formulations and tap water shows decreasing resistance with increasing deposited volume, while spray tests demonstrate close ...

Unmanned Aerial Systems for Corrosion Detection: Multi‐Sensor Technologies, Challenges, and Opportunities for Next‐Generation Inspection

Quality and Reliability Engineering International, Volume 42, Issue 6, Page 3565-3583, October 2026.
ABSTRACT Corrosion remains a critical threat to the integrity and service life of infrastructure in industries such as oil, gas, construction, renewable energy, and transportation. Traditional inspection methods, being labor‐intensive, hazardous, and often subjective, fall short in addressing modern inspection demands.
