This study presents a novel method that uses advanced deep learning models, such as YOLOv8n-seg, YOLOv8x- seg, YOLOv9, and YOLOv10, for pothole recognition and distance calculation. The proposed technology locates potholes on the road (left, center, or right), measures their distances from the car, and classifies them. The proposed system then enhances road safety by alerting drivers in real-time using text-to-speech (TTS) technology. The proposed strategy improves the detection robustness and accuracy by integrating numerous models, unlike earlier approaches. The research findings show notable gains in detecting accuracy and speed, qualifying it for real-time applications. The findings of this study can greatly lower potholerelated traffic accidents and aid in the development of advanced driver assistance systems (ADAS).

We propose and experimentally demonstrate a simple directional bending sensor based on an in-line Mach-Zehnder interference structure of the single mode fiber (SMF)-multimode fiber (MMF)-asymmetrical twin-core fiber (ATCF)-MMF-SMF. Due to the asymmetric structure in twin-core fiber, this sensor can discriminate different bending directions. The interference spectrum shifts with the change of curvature. Furthermore, the sensor exhibits a linear response with a maximum bending sensitivity of 33.48 and -38.72 nm/m(-1) in the curvature range from 0 to 3.01 m(-1) for bending directions at -x (180 degrees) and +x (0 degrees) directions, respectively. The proposed fiber sensor has great potential in the future Internet of Things (IoT) due to its advantages, such as low cost, compactness, and high bending sensitivity.

Serverless workflow applications, composed of multiple serverless functions, are increasingly popular in production. However, inter-function communication and cold start latency remain key performance bottlenecks. This paper introduces AlloyStack, a library operating system (LibOS) tailored for serverless workflows. AlloyStack addresses two major challenges: (1) reducing cold start latency through on-demand OS component loading and (2) minimizing data transfer overhead by enabling functions within the same workflow to share a single address space, eliminating unnecessary data copying. To ensure secure isolation, AlloyStack uses Memory Protection Keys (MPK) to separate user functions from the LibOS while maintaining efficient data sharing. Our evaluation shows that AlloyStack reduces cold start times by 98.5% to just 1.3ms. Compared to SOTA systems, AlloyStack achieves a 7.3x to 38.7x speedup in Rust end-to-end latency and a 4.8x to 78.3x speedup in other languages for intermediate data-intensive workflows.

This study presents a methodology for synthesizing and analyzing Au:Pd nanoparticles, using the substrate removable technique, with a focus on their potential for catalytic gas sensing applications. The process begins with the deposition of NaCl onto a glass substrate via the evaporation technique. Subsequently, Au: Pd are sputtered onto the NaCl-coated substrate, with adjustments made to sputtering parameters such as time and current to finely tune composition and thickness. x-ray diffraction (xRD) is used to analyze the crystal structure of the resulting films. The optical properties of the synthesized nanoparticles are examined by analyzing the absorption spectra across a range of wavelengths from 200 to 900 nm. The Au:Pd nanoparticles are subsequently extracted from the substrate through dissolution using deionization of water. In addition, Dynamic Light Scattering (DLS) techniques are used to evaluate the distribution of particle sizes and the stability of colloidal systems. Analyzing the zeta potential of the nanoparticle solutions yields key insights into their surface charge. Demonstrating the catalytic potential of the Au:Pd nanoparticles, they are applied to a ZnO gas sensor, effectively detecting gas vapor. Remarkably, the sensor's sensitivity is enhanced and reveals efficacy across various gas concentrations. This novel approach holds great potential for the advancement of catalytic applications.
