Design of experiment for the pilot evaluation of an airborne runway incursion alerting system [PDF]

, 2008
Runway incursions pose a significant threat to the continued safety of commercial aviation. In response, the Runway Collision Avoidance Function (RCAF) was developed by the University of Malta and evaluated at Cranfield University as part of the European

Crash Behavior of DP800–DP1000 Advanced High‐Strength Steel’s Dissimilar Resistance Spot Welded Joints Under Quasi‐static and High Strain Rates

steel research international, EarlyView.
The high‐strain‐rate behavior of resistance spot‐welded DP800–DP1000 joints is investigated. Results show that microstructural gradients across BM–HAZ–FZ govern hardness, strain rate sensitivity, and failure modes. While strength increases with strain rate, energy absorption is controlled by ductility, with DP800–DP800 joints showing superior ...

Multi‐level fatigue reliability assessment of reinforced concrete railway bridges

Structural Concrete, EarlyView.
Abstract This paper presents a multi‐level reliability framework for assessing the fatigue life of reinforced concrete (RC) railway trough bridges subjected to cyclic loading. The framework incorporates increasing levels of analytical complexity and real‐world data in four steps. First, an analytical model applies S–N curves and the Palmgren–Miner rule

Explainable friction-based modeling of winter runway contaminants for GRF-compliant decision support

Transportation Engineering
Runway contamination in winter conditions remains a major safety concern for aircraft ground operations, and the implementation of the Global Reporting Format (GRF) has increased the need for objective tools to complement visual runway surface assessment.

The “We” and “Me” of Identity in Hazardous Industry Organizations: Face Work Tactics Among Practicing Engineers

Symbolic Interaction, EarlyView.
In this paper, we use Goffman's notion of “face work” to examine how pipeline engineers perform and present their working selves as competent experts. Our analysis identifies various faces and face work tactics, including a focus on professional judgment, actively selling one's expertise relative to others, protective self‐deprecatory strategies, and ...

Systematic Learning and Pedagogy Through a Modular, Progressive‐Based Simulation Modeling Framework for Complex Systems

Systems Engineering, EarlyView.
ABSTRACT Smart Transportation Systems (SmTS) will exceed complex systems with their classification as complex, sociotechnical, and AI‐based systems. Possessing a toolkit that helps systemically understand, analyze, and assess these systems will be advantageous in the early stages of the systems engineering (SE) lifecycle, and Agent Based Models (ABMs ...
