This research is centered on the application of ultrasonic technology for the online monitoring of transformer oil storage tank levels, a critical aspect in ensuring the reliable operation of power systems. The oil level within a transformer's storage tank serves as a pivotal parameter, as deviations from the normal range can precipitate a cascade of operational anomalies and inflict severe damage upon the equipment infrastructure. Our proposed system, ingeniously engineered with ultrasonic techniques at its core, is meticulously designed to execute real-time, highly accurate monitoring of the oil level[3]. By virtue of providing meticulously precise and instantaneously updated oil-level monitoring data, this research assumes a profound significance in fortifying the operational safety and optimizing the efficiency of power systems. It not only enables the preemptive detection of potential oil level fluctuations but also facilitates the implementation of timely corrective measures, thereby effectively mitigating the risks of catastrophic failures and minimizing unplanned downtime. © 2025 SPIE.

Background: Diabetic retinopathy (DR) is a leading cause of vision impairment worldwide, affecting both retinal and choroidal vasculature. While advances in imaging technology, particularly optical coherence tomography angiography (OCTA), provide new opportunities to assess choroidal changes in diabetic patients, the role of OCTA in early diagnosis and monitoring of diabetic choroidopathy remains unclear. Objective: This review aims to evaluate the potential role of OCTA in diagnosing and monitoring diabetic choroidopathy. Methods: A systematic review was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. databases including PubMed, Embase, Cochrane Library, Google Scholar, ISI, and Scopus were searched for studies on diabetic choroidopathy assessed by OCTA. Studies included were peer-reviewed, published in English, and excluded case reports, conference proceedings, and studies on treated DR patients. Two independent reviewers screened articles for eligibility based on predefined criteria. Results: OCTA allows for non-invasive, high-resolution visualization of retinal and choroidal microvasculature, providing both qualitative and quantitative data. The majority of studies indicate a significant decrease in choroidal perfusion parameters in diabetic patients without DR compared to healthy controls. Conflicting evidence exists regarding the correlation between choriocapillaris flow reduction and DR severity. OCTA may also predict changes in visual function related to choroidal perfusion, though it cannot fully replace clinical examinations. Conclusions: OCTA is a valuable tool for early detection and monitoring of diabetic choroidopathy. However, its role is limited by variability in findings and its inability to detect certain features of diabetic microangiopathy. Further studies are needed to clarify its clinical utility and standardize assessment methods. © The Author(s) 2024.

With the continuous development of photovoltaic power generation and energy storage technology, microgrid systems in industrial parks have gradually become an important means to achieve efficient use of green energy. Aiming at the energy demand of industrial parks, this paper proposes a multi-objective optimization strategy based on the cooperative operation of photovoltaic power generation and energy storage. By analyzing the fluctuation of photovoltaic power generation and the charge-discharge characteristics of the energy storage system, a multi-objective optimization model which can achieve energy balance and maximize economic benefits under different working conditions is constructed. Optimization objectives cover many aspects such as maximizing photovoltaic utilization, minimizing energy storage costs, matching load demand and reducing environmental pollution. In order to solve the multi-objective optimization problem, the non-dominated sorting genetic algorithm (NSGA-II) was used to solve the optimization model, and the actual data of the industrial park was simulated and verified. The results show that the optimization strategy can effectively improve the photovoltaic consumption rate, reduce the operating cost of the system, and ensure the stable operation of important loads, which provides a new technical solution for energy management in industrial parks. © 2025 IEEE.

The growing ubiquity of autonomous vehicles (AVs) has introduced a new attack surface for malicious actors: the embedded systems that govern a vehicle's critical operations. Security breaches in these systems could have catastrophic consequences, potentially leading to loss of control, manipulation of sensor data, or even physical harm. To mitigate these risks, robust cybersecurity measures are paramount. This research delves into a specific threat - side-channel attacks - where attackers exploit data leakage through unintentional physical emanations, like power consumption or electromagnetic waves, to steal cryptographic keys or sensitive information. While various software and hardware countermeasures have been proposed, this study focuses on the implementation of masking techniques within the realm of embedded security. Masking techniques aim to obfuscate sensitive data during cryptographic operations, making it significantly harder for attackers to exploit side-channel vulnerabilities. This research explores the suitability of a Boolean masking approach within a high-level synthesis environment. This system-level approach offers several advantages over traditional design methodologies. It facilitates faster design processes by enabling early identification and rectification of errors. Additionally, it streamlines hardware-software co-design, allowing for a more integrated and efficient security architecture within the autonomous vehicle's embedded systems. Furthermore, the system-level approach enables the application of advanced validation strategies, ensuring the effectiveness of the implemented masking techniques. To evaluate the efficacy of the Boolean masking approach, the research investigates its application to three prominent block cipher algorithms - PRESENT, AES, and Serpent - all of which are based on substitution-permutation networks (SPNs). By implementing these masked algorithms in C and simulating their performance within an embedded system contex

The traditional CubeSats development model is a one-off build designed to accomplish a specific mission using proprietary hardware and software. The specific mission requirements and associated development costs result in a lack of reproducibility for CubeSats. The Naval Academy Standard Bus (NASB) advances the concept of CubeSat modularity with a design that physically separates a fully-functional standalone 1U bus from an independently-developed 1U or 2U customer payload module with a 10-pin wiring harness serving as the sole electrical interface between bus and payload modules. Residing within the standard bus module the main onboard computer (OBC) handles uplink and downlink communications and connects the NASB to the payload module through two interface boards: the Bus Board and the Payload Interface Board (PIB). Ground commands received by the NASB pass through the Bus Board to the PIB in the payload module, through which they are communicated to the payload via universal asynchronous receiver/transmitter (UART) protocol. Messages and stored data generated by the payloads are stored on a secure digital card within the PIB, to be passed on to NASB and downlinked to the ground station. This modular design allows for independent development of payloads, shortening CubeSat development timeline by eliminating the need for bus development in parallel with payload development. © 2025 The Authors.

In order to understand the digital management of carbon emissions in complex power systems, a research on digital management of carbon emissions in complex power systems based on big data has been proposed. This paper starts with the supply side emission reduction of the power sector in City A, and uses the LEAP model to set up four scenarios. It analyzes the medium and long-term emission reduction path planning of the power sector, and comprehensively evaluates each emission reduction path from the perspectives of emission reduction and cost. The experimental results show that: (1) due to the rapid growth of power demand, even under the extreme scenario assumption, there will be no peak carbon emissions in the power sector of City A by 2030;(2) The emission reductions of A city's power department in the planning scenario, positive scenario, and extreme scenario are 2.694 million tons, 7.984 million tons, and 10.939 million tons of CO, respectively, accounting for 4.8%, 14.4%, and 21.8% of the total carbon emissions in the reference scenario, indicating that A city's power department has significant room for emission reduction. © 2025 SPIE.

The pulse width parameter of integrated circuits is an important technical indicator for measuring the system's high-speed performance and rapid response capabilities, directly affecting the device's response speed and accuracy. Achieving traceability of integrated circuit time characteristic parameters is fundamental to ensuring the core performance of the system. The pulse width calibration device for integrated circuit testing systems calibrates the system by reproducing the behavior model of the parameters. Traditional waveform generation methods typically rely on cyclical reading of waveform memory, resulting in complex system designs, high storage resource usage, and lower waveform accuracy. To address these issues, a standard pulse width and rise/fall time waveform generation module based on an "FPGA + DAC" architecture has been designed. By directly utilizing the timing logic resources of the FPGA, multiple data modules are set up to generate waveform data in parallel, making waveform parameter adjustment more flexible and reducing waveform generation response time. Additionally, with the integration of an internal time parameter correction module, the accuracy and stability of the generated signal's time parameters are further improved, meeting the requirements for high-precision calibration. © 2025 SPIE.

The rapid growth of real-time data in power systems, driven by the integration of smart grid technologies and digitalization, presents significant challenges for efficient data processing and decision-making. Traditional batch processing methods are inadequate for handling the high velocity and large volume of streaming data, leading to latency and scalability issues. This paper proposes a real-time data processing and optimization scheduling scheme for power systems using Kafka and Storm technologies. Kafka efficiently collects and buffers streaming data from multiple sources, ensuring data integrity and low-latency communication, while Storm performs distributed real-time processing for complex event detection and rapid decision-making. The architecture also integrates HBase for scalable storage and fault-tolerant data management. Compared to traditional methods, the proposed solution demonstrates improved data processing speed, reduced system latency, and enhanced scalability. The results validate the effectiveness of this approach in supporting intelligent monitoring and operational optimization for modern power grids, paving the way for more reliable and efficient power system management. © 2025 SPIE.
