This study presents a patient-specific, one-way coupled CFD–DEM framework to demonstrate that LDL-surrogate deposition in a middle cerebral artery bifurcation is governed by the combined influence of local geometry and hemodynamic conditions, revealing deposition asymmetries that surface-based hemodynamic descriptors alone cannot predict.
This paper presents the design, implementation, and validation of an open-source, low-cost educational testbed within a Learning Factory that integrates cooperative mobile robots, collaborative arms, and AI-driven vision to effectively teach Industry 4.0 principles through project-based learning.
This paper presents a quasi-optic, multi-receiver radio frequency system that simultaneously delivers wireless power to remote devices and enables machine learning-based environmental sensing, such as breathing detection and people localization, by analyzing power output fluctuations without requiring dedicated active receivers or additional transceiver chains.
This paper introduces NEC Hands, a low-cost (approximately USD 30) wearable VR glove that delivers accurate five-degree-of-freedom finger tracking and proportional kinesthetic force feedback with low latency, significantly enhancing user presence compared to bare-hand tracking while overcoming the high cost barriers of existing commercial haptic solutions.
This paper proposes a crack detection method for metal plates that converts multi-channel acoustic signals into time-series acoustic images and utilizes a lightweight transformer model to achieve highly accurate and efficient detection of cracks with varying positions and lengths.
This study utilizes a calibrated PFC2D numerical model to investigate the mechanical response and mesoscopic bond-break evolution of layered cemented tailings backfill under biaxial confinement, revealing that peak deviatoric stress does not increase monotonically with confinement, tensile bond breaks dominate failure, and reversing the layer order yields no reproducible strength advantage.
This paper introduces a new adaptive and accuracy-aware method, ES-MDA-A2, within a three-step framework that effectively balances the trade-off between accuracy and computational efficiency in ensemble-based inverse problems by dynamically adjusting update sizes based on a targeted accuracy and maximum assimilation limit.
This study demonstrates that a fourth-order brittle phase-field model can effectively predict the crack patterns and peak loads of ductile EN AW-6060 aluminum alloy specimens with non-aligned pre-notches within 3.5% of experimental results, validating its utility as a conservative design tool without explicitly modeling plastic dissipation.
This study experimentally investigates the smoke temperature distribution in longitudinally ventilated mountain tunnels with lateral-opening vertical shafts under varying fire sizes and ventilation conditions, ultimately developing empirical correlations to predict maximum excess and longitudinal temperatures for improved fire safety system design.
This paper proposes a spectral clustering-based transmission expansion plan for Nigeria's 330 kV grid that restructures the network into six viable islands aligned with geopolitical zones, thereby transforming a collapse-prone single synchronous area into a resilient system capable of preventing nationwide blackouts while significantly reducing losses and critical contingencies.
