Deflection‐based assessment of residual prestress in simply‐supported bridges accounting for creep variability

open access: yesStructural Concrete, EarlyView.
Abstract Several test methods have been proposed in the literature for measuring the level of residual prestress, most of them involving either semi‐ or fully destructive techniques for local measurements which could be highly sensitive to boundary conditions and execution details.

Quantifying and Tracking Flexibility of System Elements to Support (Re)Design Decision‐Making

open access: yesSystems Engineering, EarlyView.
ABSTRACT Evolving objectives and requirements, risk management processes, and external disruptions frequently drive change in engineered systems. Due to these pressures, system architects must anticipate and manage change throughout a system's lifecycle. Yet, managing change is challenging due to the risk of change propagation.

Understanding STEM Coursetaking Among English Learner Subgroups: Longitudinal Evidence From Four State Policy Contexts

open access: yesTESOL Quarterly, EarlyView.
Abstract Although a substantial body of research documents the problem of course tracking for students classified as English learners (ELs), very little work has addressed the notably different challenges that subgroups of ELs face across different state policy contexts.

Enhancing generalized spectral clustering with embedding Laplacian graph regularization

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
Abstract An enhanced generalised spectral clustering framework that addresses the limitations of existing methods by incorporating the Laplacian graph and group effect into a regularisation term is presented. By doing so, the framework significantly enhances discrimination power and proves highly effective in handling noisy data.

Robotic Hand‐Arm Coordinated Skill Learning for Tool Manipulation Tasks

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT This paper focuses on the specific scenario of tool manipulation and presents a novel framework enabling robots to acquire tool manipulation skills through learning from human demonstrations. While there have been numerous studies on robotic manipulation skill learning, most of them fail to fully leverage the combined advantages of coordinated
