ESG-4D Valuation with Modern Parametric Formulas: A Quantitative Model for Integrating Environmental, Social and Governance Criteria into Construction Project Valuation in Peru

This study introduces and validates the ESG-4D model, a quantitative framework that integrates Environmental, Social, and Governance criteria directly into parametric construction cost formulas within Peru's regulatory context, demonstrating that this approach reduces financial uncertainty by 12–18% and optimizes decision-making compared to traditional valuation methods.

From Linear Waste to Closed-Loop Value: A Digital Twin-Enabled Parametric Cost Architecture for Circular Construction in Peru

This study proposes a digital twin-enabled parametric cost architecture that integrates circular economy principles to quantify potential waste valorization and lifecycle cost reductions for Peru's construction sector, while emphasizing that its simulated projections require field validation before regulatory or investment application.

Evidence-Weighted Mission Suitability Assessment of Water-Based Small-Spacecraft Propulsion Architectures

This paper introduces the Evidence-Weighted Mission Suitability Index (EW-MASI) to evaluate and rank various water-based propulsion architectures for small spacecraft, concluding that electrothermal resistojets are the most suitable near-term option for conservative maneuvers while other water-based systems offer specific advantages for impulsive, long-duration, or deep-space missions.

RL-Based Delay Minimization for Computation Offloading in IRS- and RHS-Enhanced MEC Systems

This paper proposes a Deep Deterministic Policy Gradient (DDPG)-based reinforcement learning framework to jointly optimize IRS phase shifts, RHS antenna amplitudes, and task offloading decisions in an IRS- and RHS-enhanced mobile edge computing system, thereby significantly minimizing overall task execution delay compared to conventional approaches.

Active Steering of Material Flow in Large-Scale Bellows Roll Forming via Spatially Modulated Die Friction

This paper proposes and validates a novel hybrid laser surface texturing strategy that spatially modulates die friction to actively steer material flow from the root to the crest, thereby significantly reducing wall thinning and improving structural integrity in large-scale bellows roll forming.

Force–vibration coupling and vibration suppression in band sawing using bio-inspired continuous curved tooth geometry​

This study demonstrates that implementing bio-inspired continuous curved tooth geometry in band sawing effectively suppresses cutting vibrations by redistributing stress and smoothing force fluctuations, thereby establishing a direct link between tooth design and excitation-regulated dynamic stability without requiring additional structural stiffness or active control.
