The Challenges and Achievements of Experimental Implementation of an Active Transfemoral Prosthesis Based on Biological Quasi-Stiffness: The CYBERLEGs Beta-Prosthesis

open access: yesFrontiers in Neurorobotics, 2018
The CYBERLEGs Beta-Prosthesis is an active transfemoral prosthesis that can provide the full torque required for reproducing average level ground walking at both the knee and ankle in the sagittal plane. The prosthesis attempts to produce a natural level

On validation of multibody musculoskeletal models [PDF]

open access: yesProceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 2012
We review the opportunities to validate multibody musculoskeletal models in view of the current transition of musculoskeletal modelling from a research topic to a practical simulation tool in product design, healthcare and other important applications. This transition creates a new need for justification that the models are adequate representations of ...

APTNet: A Condition‐Sensitive Modulation Framework for Surface Pressure Prediction on Supersonic Aircraft

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Accurate surface‐pressure prediction over broad operating envelopes is critical for supersonic aerodynamic analysis and design. To overcome the bottlenecks of traditional computational fluid dynamics (CFD) in real‐time performance and computational efficiency, data‐driven deep learning methods have emerged. However, existing data‐driven models

Unraveling authoritarian reform decision‐making: A metacognitive–subcognitive model

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract Recent research indicates that state reforms in East and Southeast Asia have been predominantly top‐down and authoritarian‐led. However, this significant observation implicitly relies on important assumptions about authoritarian decision‐making behavior and psychology that remains understudied.

Analyzing and Optimizing Multibody Systems [PDF]

open access: yesMechanics of Structures and Machines, 1992
Optimization of holonomic as well as non-holonomic multibody systems is presented as a nonlinear programming problem that can be solved with general-purpose optimization codes. The adjoint variable approach is used for calculating design derivatives of a rather general integral type performance measure with respect to design parameters.

Standing on a common ground: a comparison of static stability approaches for pallet loading

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract At the practical level, the static stability constraint is one of the most important constraints in practical pallet loading problems, such as air cargo palletizing. Approaches to modeling static stability, which range from base support and mechanical equilibrium calculations to physical simulation, differ in workflow, focus, and assumptions ...

Multipoint Aerostructural Optimization of Wind Turbine Rotors Using a Coupled Blade‐Resolved Aerostructural Solver

open access: yesWind Energy, Volume 29, Issue 7, July 2026.
ABSTRACT Physics‐based design optimization workflows thread the needle between computational cost limitations and simulation complexity, often compromising between modeling detail and the range of operating design conditions. Multipoint aerostructural optimization of wind turbine rotors has so far been confined to low‐fidelity analyses or to high ...
