AI-Enabled Performance-Based Procurement and Life-Cycle Maintenance of Highway Bridges: Integrating Single-Bid Risk Analytics and PPP Payment Optimization

Abstract Aging bridges, tight budgets, and procurement inefficiencies require a data-driven approach to maintenance contracts. Existing evidence shows that information and communication technology (ICT)–based construction management improves site productivity but remains unevenly...

Game-Theoretic Design of International Construction Contracts: Integrating Liquidated Damages, Consortium Structures, and Performance Guarantees

Abstract Delays and cost overruns remain endemic in international infrastructure projects. This study develops a unified game-theoretic for contractor schedule incentives under liquidated damages (LDs), extensions of time (EOTs), and multicontractor or consortium structures. We m...

RL-Augmented Dual Robust Adaptive Propagated Interval Observer for Actuator and Residual-Framed Sensor Fault Detection and Isolation in Underactuated AUVs

Reliable fault detection and isolation (FDI) for actuators and sensors in underactuated autonomous underwater vehicles (AUVs) is challenging because nonlinear hydrodynamic coupling redistributes fault signatures, and persistent ocean currents can trigger false alarms. This paper...

Institutional quality, financial development, and the circular economy in Europe

The importance of financial development is widely recognized due to its positive impacts on the investment, innovation, poverty reduction, entrepreneurship and sustainable economic performance. Similarly, an efficient circular economy brings multiple benefits including the conser...
