The existing intelligent transportation system for device management and control may have some challenges, such as simplistic traffic device management, difficult traffic data storage and management, and difficult to guarantee traffic data security. These challenges all bring adverse effects to the smooth development of the work of the traffic department. To address the above problems, this paper designs a blockchain-based intelligent transportation device and data management method. The information of the devices connected to the system is anchored to the blockchain through the blockchain deposition technology, and the whole life cycle of the devices is managed. The data collection and distributed storage of the traffic devices are realized based on the smart contract technology. Combined with the tamper-evident and traceable characteristics of blockchain, this method provides scientific management of device and device data with high security and scalability, and provides ideas and methods for building a security management architecture for transportation device control system. © 2023 SPIE.

Augmented Reality (AR) technology has lately received considerable attention for its packages in diverse domains which includes gaming, education, and productivity tools. However, notwithstanding advances in AR input strategies, there remains an exceptional hole in the availability of cost-powerful and portable answers for fingers-unfastened typing in AR environments. Existing AR keyboards regularly depend upon steeply priced hardware or proprietary structures, restricting their accessibility and scalability. This research addresses these challenges by using developing an AR Keyboard the use of Raspberry Pi-a low-value, credit score-card-sized computer-coupled with OpenCV's Easy OCR model for actual-time optical person popularity (OCR). The AR Keyboard goals to improve consumer interplay and productivity with the aid of growing a digital keyboard projected onto actual-international surfaces, getting rid of the need for physical keyboards in certain contexts. The methodology involves putting in Raspberry Pi with crucial peripherals and integrating the Easy OCR (optical character recognition) version to correctly recognize textual content entered through the AR interface. The implementation covers data collection, pre-processing strategies, YOLO and OCR integration into the AR device. The overall performance of the device is evaluated based on accuracy, pace of recognition, and user delight through usability checking out. Results exhibit the feasibility and capability of the AR Keyboard, highlighting its potential for sensible use instances together with palms-free typing in augmented environments. This assignment contributes to the developing area of AR programs, supplying a value-effective and scalable answer for better human-pc interaction. © 2024 IEEE.

With the development and widespread application of Model-Based Systems Engineering (MBSE) in the aerospace domain continue to grow, System Modeling Language (SysML) has become increasingly important as the most popular modeling language in MBSE. It is crucial to provide developers with an efficient and secure SysML editing tool to enhance their productivity. However, our research has revealed issues with the existing SysML editing tools, particularly in terms of data storage, resulting in a decline in efficiency as project data grows. Therefore, this paper proposes a GEF-based SysML development tool that supports developers in creating, editing, and exporting graphics. This tool addresses the data storage issues, improving development efficiency. Additionally, we present a model validation approach and extend the existing validation rules to ensure the correctness, reliability, and security of graphical elements and diagrams. © 2023 SPIE.

The Machine-Learning-as-a-Service (MLaaS) framework allows one to grab low-hanging fruit of machine learning techniques and data science, without either much expertise for this sophisticated sphere or provision of specific infrastructures. However, the requirement of revealing all training data to the service provider raises new concerns in terms of privacy leakage, storage consumption, efficiency, bandwidth, etc. In this paper, we propose a lightweight privacy-preserving MLaaS framework by combining Compressive Sensing (CS) and Generative Networks. It's constructed on the favorable facts observed in recent works that general inference tasks could be fulfilled with generative networks and classifier trained on compressed measurements, since the generator could model the data distribution and capture discriminative information which are useful for classification. To improve the performance of the MLaaS framework, the supervised generative models of the server are trained and optimized with prior knowledge provided by the client. In order to prevent the service provider from recovering the original data as well as identifying the queried results, a noise-addition mechanism is designed and adopted into the compressed data domain. Empirical results confirmed its performance superiority in accuracy and resource consumption against state-of-the-art privacy-preserving MLaaS frameworks.

Detecting reading orders with block-based models for OCR for classical Chinese documents: concepts and demonstrations

Texts, printed or written, are the most important form of cultural preservation. This is true for Chinese studies and many cultures. For this reason, optical character recognition (OCR) is one of the most important tools for heritage preservation. With OCR and reading order detection (ROD), we convert the information in their hard-copy forms to digitized documents, allowing both lasting storage and further analysis. Given a page image, the step of ROD helps us determine the order of the texts on the page. An effective ROD reduces the cost of post-OCR human labor for correction. Rule-based and n-gram models are conceivable and popular techniques for implementing ROD, considering the coordinates and the alternative orders of the individually detected characters. In this paper, we report a block-based approach that does not rely on the n-gram techniques for ROD. Instead, we identified the text blocks, and ordered the blocks based on the ideas of learning-to-rank, and concatenated the texts within the blocks by their orders. We evaluated our approach on the MTHv2 dataset. Experimental results show that our approach achieved impressive results, reducing the position error rate (PER) to 5.4%, compared to 61.7% for heuristic methods and 56.5% for MLP, representing a significant improvement of 91.3% and 90.4%, respectively. Additional experiments show that we could have used less data than one might expect to achieve a satisfactory quality of ROD. We implemented and demonstrated a fully functioning prototype at a recent AAAI conference. ∗ The actual performance of the prototype provides solid evidence of the effectiveness and extensibility of our design to more general contexts, e.g., Japanese texts. © The Author(s) 2025.

The cold chain logistics of oysters starts from the moment they are harvested and ends when they reach the consumers' homes. The process includes various stages: pre-processing, packaging, pre-cooling, processing, cold storage, loading, transportation, and sales. Due to inadequate quality control in the logistics process, fresh oysters often experience a significant decline in quality during transportation and storage, resulting in substantial losses. To address this issue, this article presents a real-time, traceable, and visual quality monitoring system for oyster cold chain logistics. It combines RFID technology with the development of a unique binding technique for preservation boxes and utilizes a hybrid technology incorporating "RFID+4G+DTU+MQTT+cloud storage + Web" to enable real-time collection of oyster transportation environmental parameters and distributed, non-volatile, and cost-effective data storage. A supporting B-S mode system management platform was developed and deployed on a cloud server. The system, with the flow of information as its main focus, provides functions including personnel management, oyster identification and traceability, data visualization monitoring, and quality prediction. The online operation of this system has proven to be highly real-time and stable, effectively enhancing the quality monitoring capability throughout the entire oyster transportation process, and it has demonstrated significant economic and social benefits. © 2023 SPIE.
