The wearable continuous ECG monitoring and cardiovascular disease detection system has the characteristics of strong noises and big continuous data. It puts forward higher requirements on the accuracy and efficiency of the QRS recognition algorithm. The currently used QRS detection algorithms still have the problem of missed detection and false detection for continuous ECG data. Therefore, a fast R-peak recognition method based on self-adaptive wavelet threshold and Hilbert transform is proposed for processing noisy continuous ECGs. First, wavelet self-adaptive threshold filter is used to denoise the dynamic ECGs, and then the first-order difference, Shannon energy envelope extraction, Hilbert transform and self-adaptive threshold back-check technology are employed for R-peak detection. Using the proposed method, experimental results show that the accuracy, sensitivity, and specificity of the MIT-BIH arrhythmia database are 99.79%, 99.92%, and 99.87%, respectively. Using the PhysioNet/CinC Challenge 2014 dynamic ECG database, the accuracy, sensitivity and specificity are 96.89%, 97.92% and 98.92%, respectively. Furthermore, the realtime ECGs collecting from the portable ECG detector mECG-101 are also used to evaluate the method. The experimental results show that the accuracy, sensitivity and specificity reach to 97.75%, 98.25% and 99.47%, respectively. Compared with Pan-Tompkins algorithm and wavelet transform algorithm, the proposed method has higher detection accuracy and generalization ability, especially for the wide and low-amplitude QRS complexes. © 2022 ACM.

With increasing the awareness of environmentally friendly, the ship-integrated energy system (S-IES) combined with power and heating networks has become an upcoming trend in the shipbuilding industry. It decreases the consumption of fuel-based resources by integrating renewable energy resources to replace traditional fossil-based generators partly. Meanwhile, with many intelligent devices, the S-IES performs partitioned and autonomous features because of the unique operational structure. Therefore, the normal operation of S-IES is highly vulnerable, which will be bothered by the infeasibility-driven attack for shipboard devices and influenced by the uncertainties of renewable energy resources. To this end, the energy management problem (EMP) under cyber attacks for S-IES is focused on ensuring secure and green sailing in this article. To balance the number of nods and decrease the communication resources among energy devices, a partitioning algorithm is designed to construct the energy router (ER)-based energy hub (EH) for S-IES. Meanwhile, considering the tradeoff relationship between the economy and carbon emission, a multiobjective energy management model with feasible sailing constraints is designed. Then, to ensure the information exchange among EHs using ERs, a distributed resilient energy management strategy with a detection mechanism is proposed to acquire the optimal solutions under cyber attack. Finally, the theoretical analysis verifies the effectiveness of the designed distributed resilient strategy. Simulation results of different scenarios prove the great performance on ensuring secure and green sailing for ships by the constructed energy management model and its distributed resilient strategy. © 2015 IEEE.

International Journal of High Speed Electronics and Systems 2024年第4期33卷

作者： Shur, Michael Department Of Electrical Computer And Systems Engineering Rensselaer Polytechnic Institute 110 8th Street TroyNY United States

Terahertz (THz) sensing technology enables 6G communication, detection of biological and chemical hazardous agents, cancer detection, monitoring of industrial processes and products, and detection of mines and explosives. THz sensors support security in buildings, airports, and other public spaces. They found important applications in radioastronomy and space research and, more recently, in Artificial Intelligence-driven THz sensing of MMICs and VLSI. Exploding demand for data transfers will require using the 300 GHz band after 2028 or even before and will make the deployment of THz sensing electronics inevitable. This paper discusses the new physics of THz sensing and THz sensing devices. It also reviews the THz sensing market, and key THz sensor companies. © 2024 World Scientific Publishing Company.

Improving Obstacles' Low Observability Using Multi-Static RCS: Case of OHW Detection in OCAS For Flying Vehicles

引用

IEEE Transactions on Antennas and Propagation 2025年

作者： Onana, Vincent-De-Paul Nehmetallah, George School of Engineering The Catholic University of America Department of Electrical Engineering and Computer Science 620 Michigan Avenue NE WashingtonDC20064 United States

Improving obstacles' low observability is critical in radar system performance. The present study concluded that, when applied to OverHead Wire (OHW) detection in Obstacle Collision Avoidance System (OCAS) for Flying Vehicles (FV), Multi-static Radar Cross Section (RCS) from a Multi-Input Multi-Output (MIMO) radar system seems to be a way to achieve that goal. Mono-static and multi-static RCSs are derived, highlighting the advantages of multi-static RCS. Complex envelope of signals received at individual antenna active elements as a function of aspect angle is determined from a multi-static RCS scenario. The stretch processing for complex range profiles from signals received by a radar after illuminating a target is examined. 2D Range Aspect Angles Intensity (RAAI) maps based on stretch processing using mono-static and multi-static RCS of Perfect Electric Conductor (PEC) OHW and circular cylinder cable obstacles are generated. Multi-static RCS improvements relative to the normal incidence are in the order of 1.5dB, 6dB, and 7dB for the PEC circular cylinder cable P.O. theoretical model, the Feko™PEC twisted wire, and the Feko™PEC circular cylinder cable respectively. Multi-static RCS exhibits superior SNR detection differential over all aspect angles, in the order greater than 18dB for simulation cases, and in the order of 15dB for experimental cases analyzed in this study, hence the multi-static RCS is more suitable for low observable obstacles' detection, e.g. the detection of OHW obstacles for FVs' OCAS. Detection behavior from both our experimental measurement collections using a TIDEP-01012™radar and simulation results agree. © 2025 IEEE.

The latest improvements in artificial intelligence (AI) and predictive analytics have furnished new possibilities to increase the performance of choice-making techniques. Self-sustaining predictive analytics, which can rely upon the energy of AI technologies, which include natural language processing (NLP) and deep learning, has the potential to automate the complex procedure of information analysis and generate predictions with minimum human intervention. This method can allow records-pushed decision-makers to make selections faster and more appropriately and gain deeper insights into business problems. This paper overviews the opportunities for self-reliant predictive analytics powered by AI. The report will mainly discuss how AI-primarily based predictive analytics can enhance the accuracy and velocity of decision-making approaches and provide insights into client conduct and market trends, which could help inform business techniques. Moreover, the paper may also discover the security dangers posed through self-reliant predictive analytics structures and discuss capacity countermeasures to mitigate those dangers. © 2023 IEEE.

A large number of metaheuristics have been proposed and shown high performance in solving complex optimization problems. While most variation operators in existing metaheuristics are empirically designed,new operators are automatically designed in this work,which are expected to be search space independent and thus exhibit robust performance on different *** work first investigates the influence of translation invariance, scale invariance, and rotation invariance on the search behavior and performance of some representative operators. This work then deduces the generic form of translation, scale, and rotation invariant operators, and proposes a principled approach for the automated design of operators, which searches for high-performance operators based on the deduced generic form. The experimental results demonstrate that the operators generated by the proposed approach outperform state-of-the-art ones on a variety of problems with complex landscapes and up to 1000decision variables.

Modern developments in computing and electronics have made intelligent systems suitable for use in the mechanization of agricultural processes. This proposed used multilayered perceptron and radial basis function networks to forecast the temperature shifts in the mushroom cultivation chamber based on independent variables including water temperature, ambient temperature, water tap, fresh air and circulation air dampers, and water tap. Preprocessing, feature extraction, and training the model are the three phases that comprise this proposed method. Reflectance calibration, normalization, and spectral smoothing are the steps involved in data preprocessing. Feature extraction made quick work of extracting information from mushroom photos by employing the SIFT algorithm. The proposed model was trained using an IAN-Bidirectional GRU. When compared to more conventional approaches, the proposed methodology is superior. The method's application resulted in a 93.75% improvement in accuracy. © 2024 IEEE.

SiC MOSFET Solid-State Circuit Breaker-Based Motor Control Center: Design Analysis, Novel Soft Start and Soft Turn-off Strategies

引用

IEEE Journal of Emerging and Selected Topics in Power Electronics 2024年

Solid-State Circuit Breaker (SSCB) has been identified as a potential game-changing technology for DC distribution systems. However, fewer SSCB research and applications have been reported in AC due to direct competition with mechanical circuit breaker (MCB), which has a proven record as AC circuit protection device. The proposed three-phase SSCB integrates application-specific functions of soft starters, contactors, circuit breakers, and thermal relays commonly present in motor control centers (MCCs). This article primarily discusses the current protection, soft start, and contactor functions of the proposed SSCB. Key design considerations for a 380 VAC/63 A three-phase SSCB are introduced, covering semiconductor device, metal oxide varistor (MOV), snubber, and heatsink selections, as well as MOV lifetime analysis. The current fault protection of the SSCB is verified at 200 A. Furthermore, novel soft start and soft turn-off strategies are proposed. The turn-off time of both strategies is determined by a grid voltage phase-locked loop (PLL) angle instead of current sensors. Finally, both simulation and experimental results using open-loop and closed-loop soft start strategies validate a significant reduction in motor inrush current. Additionally, experimental results confirm that employing the novel soft turn-off strategy extends the lifetime of the SSCB when used as a contactor, as it does not activate MOVs. By combining the contactor, circuit breaker, and soft starter functions into one, SSCB can offer competitive advantages in MCC applications. © 2024 IEEE.

Cerberus: The Power of Choices in Datacenter Topology Design

The bandwidth and latency requirements of modern datacenter applications have led researchers to propose various topology designs using static, dynamic demand-oblivious (rotor), and/or dynamic demand-aware switches. However, given the diverse nature of datacenter traffic, there is little consensus about how these designs would fare against each other. In this work, we analyze the throughput of existing topology designs under different traffic patterns and study their unique advantages and potential costs in terms of bandwidth and latency "tax". To overcome the identified inefficiencies, we propose Cerberus, a unified, two-layer leaf-spine optical datacenter design with three topology types. Cerberus systematically matches different traffic patterns with their most suitable topology type: E.g., latency-sensitive flows are transmitted via a static topology, all-to-all traffic via a rotor topology, and elephant flows via a demand-aware topology. We show analytically and in simulations that Cerberus can improve throughput significantly compared to alternative approaches and operate datacenters at higher loads while being throughput-proportional. © 2022 Owner/Author.

Wireless Power Week (WPW)

作者： Shanti M. Garman Vanessa Affandy Joshua R. Smith Department of Electrical & Computer Engineering University of Washington Seattle USA Department of Electrical & Computer Engineering Allen School of Computer Science & Engineering University of Washington Seattle USA

Harvesting higher levels of ambient RF energy emitted by existing infrastructure has the potential to enable new charging scenarios. However, current device limitations make harvesting at high frequencies and high power levels a challenging problem to solve. In this work we present a prototype energy harvester which delivers up to 2.9 W of DC power to a resistive load and 1.6 W to a battery load, many orders of magnitude more than has traditionally been provided by RF energy harvesters. Our solution uses an array of harvesters operating in parallel and in the ultra-high frequency (UHF) band at a local cellular carrier frequency of 749 MHz. This paper presents an overview of the design, implementation, and test results of a UHF harvester array prototype and introduces potential future applications.
