Multi-Fidelity Surrogate Modelling for Uncertainty-Aware Prediction of Disturbed Velocity Fields in Virtual Flow Metering

This paper presents an auto-regressive multi-fidelity Gaussian process regression framework that fuses sparse, high-fidelity LDV measurements with abundant, biased CFD simulations to create a real-time, uncertainty-aware surrogate model for predicting disturbed velocity fields in virtual flow metering, achieving significant error reduction and reliable 95% prediction intervals.

Effect of the placement of mechanically shredded denim fabric within three-layer particleboards on their mechanical properties and internal structure

This study demonstrates that placing mechanically shredded denim fabric in the face layers of three-layer particleboards preserves mechanical performance and meets industry standards, whereas core-layer incorporation significantly reduces strength, highlighting that maintaining the board's characteristic density gradient is more critical for performance than local material densification.

Strategic retirement enhances electric vehicle battery circularity

This study demonstrates that strategically retiring electric vehicle batteries 1–2 years earlier can transform 40–50% of currently unreusable units into valuable second-life energy storage resources, significantly enhancing circularity and environmental sustainability through a proposed dynamic trade-in framework.

Feasibility of Mobile Point-to-Point Speed Enforcement: Real-World Evidence from Urban and Rural Queensland

This study demonstrates that mobile point-to-point speed enforcement is operationally feasible in Queensland, revealing that vehicle re-identification rates are primarily constrained by the number of road exits rather than camera separation distance, while also highlighting significant discrepancies between spot and average speed measurements.

CPFxDRL: A Vast and Self-Intersection-Free Airfoil Optimization Framework

This paper introduces CPFxDRL, a novel airfoil optimization framework that couples Deep Reinforcement Learning with Constructive Piecewise Functions to create a self-intersection-free, low-dimensional search space that outperforms traditional CST methods in convergence speed and geometric fidelity while highlighting the critical need for high-fidelity CFD validation to prevent reward hacking.

BanglaVowelDataset: True AC and Synthetic BC Bangla Vowel Datasets in Speech Information System

This paper introduces the BanglaVowelDataset, comprising 120 recorded air-conducted (AC) and 120 synthetic bone-conducted (BC) Bangla vowels from ten speakers, to address the lack of such resources and facilitate research in noise-robust speech processing, recognition, and speaker identification.

Towards Cooperative Mid-Course Guidance for Air-Defense: A Continuous Weapon Target Assignment Perspective

This paper proposes a continuous mid-course Weapon Target Assignment framework that integrates dynamic reassignment with trajectory guidance to enhance the autonomy, reactivity, and robustness of air-defense systems against coordinated swarm attacks, utilizing the Hungarian method for efficient real-time optimization in many-on-many scenarios.
