Aerodynamic Characteristics Optimization Design of the HALE Joined‐Wing Configuration UAV

International Journal of Aerospace Engineering, Volume 2026, Issue 1, 2026.
This study investigates the factors influencing the aerodynamic performance enhancement of the rear wing of the joined‐wing configuration UAVs by analyzing the flow field structure and flow mechanisms before and after airfoil optimization. Correspondingly, an optimization design concept tailored to joined‐wing aircraft is proposed. Focusing on the rear

Generalized Rational B‐Spline Bases via Homographic Parametrization and Applications

International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.
A new class of rational parametrization has been developed and was used to generate a new family of rational B‐splines, αGiki=0k, which depend on a parameter α ∈ (−∞, 0) ∪ (1, +∞). This family of functions satisfies, among other properties, positivity and the partition of unity.

Proposal of a Parameterized Methodology for the Hydrodynamic Design of High‐Efficiency Pelton Rotors Validated by Multiphase CFD Simulations

International Journal of Rotating Machinery, Volume 2026, Issue 1, 2026.
This work presents and validates a direct analytical methodology for the parametric hydrodynamic design of Pelton rotors. The proposed approach combines a one‐dimensional theoretical framework for defining global geometric rotor parameters with an inductive method for generating bucket geometry, formalized from a comprehensive mapping of a high ...

Comparing cranial biomechanics between Barbourofelis fricki and Smilodon fatalis: Is there a universal killing‐bite among saber‐toothed predators?

The Anatomical Record, Volume 308, Issue 11, Page 2962-2975, November 2025.
Abstract Saber‐tooths, extinct apex predators with long and blade‐like upper canines, have appeared iteratively at least five times in the evolutionary history of vertebrates. Although saber‐tooths exhibit a relatively diverse range of morphologies, it is widely accepted that all killed their prey using the same predatory behavior. In this study, we CT‐

Domain‐adaptive self‐supervised learning for corrosion detection and 3D building information model mapping in steel tunnels

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 26, Page 4425-4447, 7 November 2025.
Abstract Accurate detection and localization of steel corrosion in tunnel infrastructure remains a major challenge, particularly under conditions of variable lighting, limited accessibility, and visual domain shifts common in real‐world inspection scenarios.
