Dynamic Performance Enhancement of a High‐Agility Hypersonic Mechanical System via a Learning‐Augmented Robust Control Architecture

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The design of control systems for high‐agility mechanical systems operating in extreme environments is a significant challenge in nonlinear dynamics. This paper addresses the complex dynamic control problem of a hypersonic interceptor, modeled as a multi‐input multi‐output (MIMO) mechanical system characterized by strong aerodynamic cross ...

Degradation of Crystalline Si‐Based Solar Modules With Varying Material Combinations—Part I: Encapsulant Degradation

Progress in Photovoltaics: Research and Applications, EarlyView.
This work deals with the degradation of solar modules with varying material combinations under accelerated aging conditions. By in situ moisture measurements and simulations of oxygen ingress, the consumption of stabilizing additives and polymer degradation can be correlated spatially resolved with the penetrating stressors.

Prevalence and drivers of ectoparasite abundance on Norway rats (Rattus norvegicus) in New York City residential complexes

Pest Management Science, EarlyView.
Norway rat ectoparasite burden varied by residential microhabitat, host traits, and trap type, showing that urban rodent management should address both rat burden and ectoparasite persistence in residential buildings. Abstract BACKGROUND Norway rats, Rattus norvegicus (Berkenhout), can carry ectoparasites of public health importance.

Multi‐scale flow analysis for scale‐aware urban canopy models

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We found that scale‐aware models are necessary when numerical weather prediction models approach hectometric resolution, which is associated with a characteristic length‐scale of morphological heterogeneity. This morphology‐dependent length‐scale indicates that resolved and unresolved heterogeneity are equally important.

Design of a Novel Gripping Mechanism and Dual Manipulator Robotic System for Apple Harvesting Using Tractor

Journal of Field Robotics, EarlyView.
ABSTRACT The architecture of apple orchards can be converted to easier operation by implementing the use of a low‐cost, tractor‐mounted, dual manipulator based on a robotic harvesting system with lower degrees of freedom (DoF). To accurately avoid injuries by detecting apples, an efferent, real‐time vision system that includes a new gripping mechanism ...
