This study presents an untethered, insect-scale amphibious microrobot that utilizes a single set of actuators to generate an asymmetric vibration pattern, enabling ultrafast, controlled locomotion and seamless transitions between terrestrial and aquatic environments.
The Metal Plasma Ion Thruster (MPIT) is a novel, compact propulsion system for small satellites that utilizes a cathodic arc source to accelerate various metal ions to high specific impulses (3,900–10,300 s) with ~50% efficiency, offering thrust comparable to Hall Effect Thrusters while overcoming the low thrust-to-power limitations of previous metal plasma designs.
Despite employing a hybrid ensemble approach to address severe class imbalance in predicting rainfall-induced landslides in Rwanda, this study found that a Random Forest model performed comparably to the ensemble while both struggled with low recall and poor probability calibration, leading to a recommendation for Random Forest deployment with adjusted thresholds and further multi-district validation.
This paper introduces a Decision-Dependent Adversarial Bayesian Optimization (DD-ABO) framework that integrates full-year simulations and candidate-specific attack evaluations to optimize solar and battery storage planning, demonstrating that strategically diversifying deployment structures significantly enhances cyber resilience against worst-case attacks without requiring substantial additional capital investment.
This paper presents a hardware Trojan-resilient FPGA framework that utilizes adaptive runtime reconfiguration with Evolvable Hardware and an enhanced CFG-LUT architecture, combined with an optimized Genetic Algorithm, to rapidly restore circuit functionality while minimizing hardware overhead and recovery latency.
This study utilizes 2D CFD simulations with the SST turbulence model to systematically redesign and evaluate a scramjet intake at Mach 4, demonstrating how specific geometric modifications optimize supersonic compression and minimize total-pressure losses through controlled shock-wave interactions.
This paper presents a novel active perception controller that enhances the observation of space-bounded repetitive dynamic events by approximating the target's motion envelope and utilizing the null-space of the main task to autonomously adapt the viewpoint, thereby minimizing uncertainty and keeping the entire motion within the camera's field-of-view.
This study demonstrates through validated finite element simulations that a rhomboidal spacer geometry enhances the controlled deformation and dynamic response of steel guardrails during impact, while remaining compatible with industrial cold sheet metal manufacturing processes.
This paper proposes CLGDA-Net, a novel deep learning framework integrating cross-level gated context fusion, multi-dilation context attention, and multi-scale dual-attention fusion to overcome challenges like complex backgrounds and scale variations, thereby achieving state-of-the-art landslide segmentation performance on remote sensing imagery.
This study utilizes RANS simulations to demonstrate that decreasing the aspect ratio of a finite NACA 2412 wing significantly delays stall onset and alters spanwise separation topology through tip-vortex downwash, providing a validated reference dataset for low-aspect-ratio wing design.
