This paper offers a formal data-driven scheme for constructing control barrier certificates (CBC) and synthesizing safety controllers for discrete-time control systems. Our framework accommodates scenarios where the mathematical model is unknown, while also considering the presence of wireless communication networks between sensor-controller and controller-actuator links. While existing literature extensively addresses the design of CBC, there has been a notable lack of attention in incorporating wireless communication networks to tackle potential packet losses. This gap poses a greater challenge when considering the absence of knowledge about the system's model, a crucial aspect in real-world applications. Given a particular rank condition for unknown wirelessly-connected systems, our method provides a linear matrix inequality, constructed based on two input-output trajectories of the system, offering a probabilistic safety assurance across an infinite time horizon. We showcase the efficacy of our data-driven approach over a wirelessly-connected synchronous motor with an unknown model.

In the realm of power systems engineering, heightened attention has been directed towards the concept of Transient State Estimation (TSE) due to its potential for enhancing system analysis within smart grids. This paper presents an efficient approach to address challenges in power grid monitoring by introducing adaptive architectures for real-time power system estimation, focusing on the pivotal role of TSE in enhancing grid resilience and efficiency. Leveraging the Vitis High-level Synthesis (HLS) tool and the Xilinx Zynq UltraScale+ MPSoC ZCU104 platform, the study proposes four distinct FPGA architectures. These architectures are systematically optimized for latency and resource utilization, emphasizing the delicate balance between these factors. The achieved goal through the paper is to demonstrate the feasibility of supporting real-time TSE for a representative network via an FPGA implementation.

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-timeapplications. The findings of this study can greatly lower potholerelated traffic accidents and aid in the development of advanced driver assistance systems (ADAS).

We introduce a simple yet effective approach for dense depth reconstruction that operates directly on raw disparity data, eliminating the need for additional disparity refinement stages. By leveraging disparity maps generated from conventional stereo methods, we train a U-Net-based model to directly map disparity to depth, bypassing complex feature engineering. Our method capitalizes on the robustness of traditional stereo matching techniques to varying scenes, focusing exclusively on dense depth reconstruction. This approach not only simplifies the training process but also significantly reduces the requirement for large-scale training datasets. Extensive evaluations demonstrate that our method surpasses classical stereo matching frameworks and state-of-the-art classical post-refinement techniques, achieving superior accuracy. Additionally, our approach offers competitive inference times, comparable to classical as well as end-to-end deep learning methods, making it highly suitable for real-time robotic applications.

Light detection and ranging (LiDAR) sensor has become one of the primary sensors in robotics and autonomous system for high-accuracy situational awareness. In recent years, multi-modal LiDAR systems emerged, and among them, LiDAR-as-a-camera sensors provide not only 3D point clouds but also fixed-resolution 360 degrees panoramic images by encoding either depth, reflectivity, or near-infrared light in the image pixels. This potentially brings computer vision capabilities on top of the potential of LiDAR itself. In this paper, we are specifically interested in utilizing LiDARs and LiDAR-generated images for tracking Unmanned Aerial Vehicles (UAVs) in real-time which can benefit applications including docking, remote identification, or counter-UAV systems, among others. This is, to the best of our knowledge, the first work that explores the possibility of fusing the images and point cloud generated by a single LiDAR sensor to track a UAV without a priori known initialized position. We trained a custom YOLOv5 model for detecting UAVs based on the panoramic images collected in an indoor experiment arena with a motion capture (MOCAP) system. By integrating with the point cloud, we are able to continuously provide the position of the UAV. Our experiment demonstrated the effectiveness of the proposed UAV tracking approach compared with methods based only on point clouds or images. Additionally, we evaluated the real-time performance of our approach on the Nvidia Jetson Nano, a popular mobile computing platform.
