In the past a few years, underwater acoustic networks have developed as a powerful technique used for variety of applications. Ad-Hoc On-Demand Distance Vector (AODV) is a popular and effective routing protocol, while it is not suitable for underwater usage due to the features of underwater acoustic channel such as low data rate, long delay, limited bandwidth and energy. In this paper, we propose an improved AODV based on implicit acknowledgement which employs broadcast features of nodes to overhear packets and retransmit those that fail to be transmitted. In addition, residual energy is considerded for energy balancing. Finally, the in-field experiment results shows that our proposed protocol can select the route with more residual energy for energy balancing. And our proposed protocol also outperforms AODV in terms of throughput and packet discovery ratio. So it is more suitable for underwater scenarios that require high transmission reliability.

It is of great importance to rationally design and fabricate electrode materials with high utilization and unexceptionable re-cycling performance in energy storage device including supercapacitors (SCs). Herein, Mn-doped Ni(OH)2 nanosheets with oxygen vacancies in-situ grow on the Co3O4 nanobelts on carbon cloth (CC) to form a core-shell heterostructure (Co3O4@Mn-Ni(OH)2/CC). The obtained Co3O4@Mn-Ni(OH)2/CC electrode has an outstanding specific capacity of 313.4 mA h g–1 (1128.4 C g–1 or 2051.6 F g–1) at 1 A g–1, ca. 6.4 times that of the Ni(OH)2/CC electrode (48.9 mA h g–1). The hybrid supercapacitor (HSC) constructed by activated carbon (AC) and Co3O4@Mn-Ni(OH)2/CC displays a marvelous energy density of 65.5 W h kg−1 at 800 W kg−1, and 93.0% of the capacity retention over 10000 repeated charging/discharging cycles at 5 A g–1, superior to the Co3O4@Ni(OH)2/CC//AC HSC (36.5%) and Mn-Ni(OH)2/CC//AC HSC (53.9%). The results of the characterizations and density functional theory (DFT) calculation show that the Mn-doping and subsequent induced oxygen vacancies promote the conductivity, and inhibit the irreversible phase transition of Ni(OH)2 during the charging/discharging process which contributes to the long-time cycling stability of the electrode. Moreover, the core-shell heterostructure fosters the exposure of active sites and reduces the charge transfer resistance due to the interfacial interaction. This work provides some insight into the rational design and fabrication of electrode materials with high utilization in SCs. © 2023, The Authors. All rights reserved.

Convolutional Neural Network-Based Machine Vision for Non-Destructive Detection of Flooding in Packed Columns

Sensors 2023年第5期23卷 2658-2658页

作者： Liu, Yi Jiang, Yuxin Gao, Zengliang Liu, Kaixin Yao, Yuan Institute of Process Equipment and Control Engineering Zhejiang University of Technology Hangzhou310023 China Shanxi Key Laboratory of Signal Capturing & Processing North University of China Taiyuan030051 China Department of Chemical Engineering National Tsing Hua University Hsinchu300044 Taiwan

In chemical processes, packed columns are frequently employed in various unit operations. However, the flow rates of gas and liquid in these columns are often constrained by the risk of flooding. To ensure the safe and efficient operation of packed columns, it is crucial to detect flooding in real time. Conventional flooding monitoring methods rely heavily on manual visual inspections or indirect information from process variables, which limit the real-time accuracy of results. To address this challenge, we proposed a convolutional neural network (CNN)-based machine vision approach for non-destructive detection of flooding in packed columns. Real-time images of the packed column were captured using a digital camera and analyzed with a CNN model, which was been trained on a dataset of recorded images to identify flooding. The proposed approach was compared with deep belief networks and an integrated approach of principal component analysis and support vector machines. The feasibility and advantages of the proposed method were demonstrated through experiments on a real packed column. The results showed that the proposed method provides a real-time pre-alarm approach for detecting flooding, enabling process engineers to quickly respond to potential flooding events. © 2023 by the authors.

Ltd Ningbo Joyson Advanced Energy Research Institute Co. Ltd Northwestern Polytechnical University Ningbo China Ningbo Joyson Advanced Energy Research Institute Co. Ltd Ningbo China

This paper focuses on voltage control for a dynamic wireless charging system of electric vehicles based on an extended state observer. Each dynamic wireless charging system will suffer from complex disturbances, leading to the challenge of output voltage control. To address this issue, we propose a disturbance rejection control scheme that utilizes an extended state observer to estimate the unknown disturbances. A dynamic sliding-mode surface is designed to suppress estimation error, and a sliding mode control law based on the estimated information and sliding-mode surface is proposed to accurately track the expected voltage. We prove the stability of the closed-loop system, and simulation results confirm the effectiveness of the proposed disturbance rejection control scheme for dynamic wireless charging systems based on the extended state observer.

Background::Streptococcus suis ( S. suis) can be transmitted to humans through exposure to pigs or consumption of raw pork and causes serious diseases. Although infection through skin abrasions is considered an important route of transmission, few studies have reported skin injuries in patients during exposure or before infection. This study explored a rare instance of intraocular infection and bilateral deafness caused by S. suis and emphasized the importance of timely diagnosis and treatment to prevent disease progression. Methods::The diagnosis was made on the basis of clinical symptoms, imaging, molecular detection, and isolated culture methods. Drug susceptibility testing was conducted to determine the effectiveness of antibiotics. Whole-genome sequencing was used to identify the strain’s sequence type and serotype as well as the presence of pathogenicity islands (PAIs).Results::A patient with intraocular infection and bilateral deafness was diagnosed with an S. suis infection. The infection was hypothesized to result from interspecies transmission due to the patient’s occupation and recent skin damage. The isolated strain was sensitive to ampicillin, ceftriaxone, vancomycin, linezolid, levofloxacin, and meropenem. Whole-genome sequencing revealed that the strain belonged to sequence type 353 and serotype 2, showing close similarity to strains isolated from wild boars in Chinese provinces. The strain lacked the 89 complete kb PAI but had a 33 kb PAI with high similarity, potentially indicating variable virulence. Conclusion::This study highlights the importance of employing multiple diagnostic strategies for the timely identification and treatment of S. suis infections. The presence of a potentially less virulent strain emphasizes the need for continuous surveillance and monitoring of emerging S. suis infections, particularly in Asian countries with high-risk populations associated with the pig farming industry.
