Deep Reinforcement Learning‐Based Control for Real‐Time Hybrid Simulation of Civil Structures

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Real‐time Hybrid Simulation (RTHS) is a cyber‐physical technique that studies the dynamic behavior of a system by combining physical and numerical components that are coupled through a boundary condition enforcer. In structural engineering, the numerical components are subjected to environmental loads that become dynamic displacements of the ...

Economic problems of aircraft equipment recovery

, 2016
The formation of effects of different order in the process of aircraft equipment recovery is investigated. Changes of idle time of aviation equipment, depending on the cost of its recovery and maintenance are estimated. Economic problems of reasonable implementation of qualitative aircraft recovery are considered.

Designing for unanticipated uses: How product attributes shape community‐led exaptation

Strategic Management Journal, EarlyView.
Abstract Research Summary Users often discover new uses for products that firms may later commercialize, which we call community‐led exaptation. We examine how product attributes shape users' discovery of new functions versus new functionalities. Using 1925 IKEA product hacks, we find that modularity increases the likelihood of new functions.

Landing scheduling for carrier aircraft fleet considering bolting probability and aerial refueling

Defence Technology
Recovery is a crucial supporting process for carrier aircraft, where a reasonable landing scheduling is expected to guide the fleet landing safely and quickly. Currently, there is little research on this topic, and most of it neglects potential influence

A Preliminary Exploratory Measurement Model for Systems Thinking in Defence and Aerospace Engineering: A Bifurcated Framework Developed via Multiple Correspondence Analysis

Systems Research and Behavioral Science, EarlyView.
ABSTRACT Modern engineering faces a ‘complexity crisis’ characterized by interlinked, multidisciplinary ‘wicked problems’, particularly within the defence and aerospace sectors. Although systems thinking is recognized as a critical competency for navigating this environment, empirical quantitative frameworks for its measurement remain limited.
