This paper presents "Spectral Doughnut," a compact, metasurface-enabled snapshot hyperspectral imager that maps wavelength onto the azimuthal coordinate of a ring-shaped point-spread function to enable efficient spectral characterization of unresolved resident space objects, validated through a SWIR proof-of-concept design and calibration.
This study investigates the mechanical behavior and dual-peak strength evolution of a coal pillar–granular backfill composite body in highwall mining, revealing how pillar width and granular material height influence strength through established models to support green and safe resource recovery.
This paper introduces Generative Topology Optimization (GenTO), a unified framework that leverages a diffusion model trained on a large topology dataset to steer topology distributions toward high-performing, task-specific solutions for diverse architected metamaterial design problems, thereby enabling the reuse of learned topology knowledge across heterogeneous objectives and constraints.
This paper presents "MOM's Care," a proof-of-concept wearable IoT framework integrated with an Android application that continuously monitors maternal and fetal vital signs via a smart belt to provide real-time risk alerts and data visualization, aiming to enhance prenatal care accessibility in resource-constrained settings.
This study evaluates the performance and sustainability of M35 concrete incorporating nano titanium dioxide and coal bottom ash as a fine aggregate substitute, demonstrating that this combination enhances mechanical strength, durability, and microstructural integrity while reducing environmental impact and reliance on natural sand.
This paper presents a low-cost, embedded real-time prototype using Arduino and ultrasonic sensors to detect blind-spot pedestrians and wirelessly alert both drivers and pedestrians, demonstrating reliable detection within 1.5 meters and rapid response times suitable for enhancing school bus safety.
This paper proposes and validates a "University Living Lab" framework at the University of Debrecen that integrates human-centered automation and circular engineering within a Quadruple Helix ecosystem to bridge the gap between academic research and industrial application, thereby accelerating the Industry 5.0 twin transition through multi-disciplinary innovation and scalable regulatory support.
This paper presents a state-of-the-art review of 97 studies on bus bridging in urban rail systems, categorizing existing research into nominal, disruption-response, and robust operations to identify current challenges and propose future directions for transforming bus bridging from a reactive emergency measure into a proactive, data-driven component of resilient urban transport.
This paper presents an open-source, self-configurable IoT gateway utilizing an ESP32 microcontroller and cellular modules without native library support, featuring a dual-core architecture with a web-based interface, AT command-driven connectivity, and optimized data transmission to the TagoIO cloud for remote monitoring applications.
This study demonstrates that conventional scalar porosity models fail to explain the disproportionate strength loss in aluminum-aerated dense concrete, revealing instead that pore morphology characteristics—specifically increased pore density, reduced circularity, and bubble coalescence—govern mechanical performance more critically than total porosity alone.
