Since the global spread of COVID-19 began in November 2019, it has become a widely searched term online. COVID-19 remains a severe public health issue requiring ongoing efforts until a permanent solution is established. Asymptomatic individuals pose a significant risk as they can unknowingly transmit the disease and may suffer from severe lung damage. To combat the disease and save lives, accurately predicting and monitoring asymptomatic patients is crucial. This research introduces a machine learning model to detect symptomatic patients based on data such as fever, blood oxygen levels, heart rate, cough intensity, and motion activities. A deep dense neural network (DNN) model was developed to identify COVID-19 infections, achieving high performance with 98% accuracy and a loss value of 0.1 on both training and validation datasets. Additional improvements could be attained by extending training duration or adjusting the learning rate. This AI-based solution demonstrates promise in accurately and efficiently detecting COVID-19 infection using input data such as fever, SpO2 percentage, cough intensity, and heart rate. The proposed model can be particularly beneficial in hospital settings, especially during quarantine periods. © 2024 IEEE.

The study investigates the challenges posed by' partial shading conditions' (PSCs) on a performance and efficiency of solar photovoltaic (PV) systems. The primary goal is to find the best photovoltaic array setup to optimize power output while reducing efficiency losses caused by mismatching. The researchers evaluate various PV configurations such as Series (S), Series-Parallel (SP), Total Cross Tied (TCT), Bridge Linked (BL), Honey Comb (HC), and a hybrid of TCT and BL called TCT-BL, focusing on a 4x4 array layout. Six different shading patterns are examined, including diagonal, 'short and narrow', 'short and wide', 'long and narrow', 'long and wide', and random. Based on simulations using Matlab/Simulink and a 130W PV module model, the study suggests that the TCT-BL configuration offers superior power generation, efficiency, and reduced mismatching loss compared to other configurations under most PSCs examined. © 2023 IEEE.

The number of mobile devices accessing wireless networks isskyrocketing due to the rapid advancement of sensors and wireless communicationtechnology. In the upcoming years, it is anticipated that mobile datatraffic would rise even more. The development of a new cellular networkparadigm is being driven by the Internet of Things, smart homes, and moresophisticated applications with greater data rates and latency *** are being used up quickly due to the steady growth of smartphonedevices andmultimedia apps. Computation offloading to either several distantclouds or close mobile devices has consistently improved the performance ofmobile devices. The computation latency can also be decreased by offloadingcomputing duties to edge servers with a specific level of computing ***-to-device (D2D) collaboration can assist in processing small-scaleactivities that are time-sensitive in order to further reduce task delays. The taskoffloading performance is drastically reduced due to the variation of differentperformance capabilities of edge nodes. Therefore, this paper addressed thisproblem and proposed a new method for D2D communication. In thismethod, the time delay is reduced by enabling the edge nodes to exchangedata samples. Simulation results show that the proposed algorithm has betterperformance than traditional algorithm.

Flue gas heat loss accounts for a significant component of theoverall heat loss for coal-fired boilers in power plants. The flue gas absorbsmore heat as the exhaust gas temperature rises, which reduces boiler efficiencyand raises coal consumption. Additionally, if the exhaust gas temperatureis too high, a lot of water must be used to cool the flue gas for the wetflue gas desulfurization system to function well, which has an impact onthe power plant’s ability to operate profitably. It is consequently vital totake steps to lower exhaust gas temperatures in order to increase boilerefficiency and decrease the amount of coal and water used. Desulfurizationperformance may be enhanced and water use can be decreased by reasonableflue gas characteristics at the entry. This study analyzed the unit’s energyconsumption, investment, and coal savings while proposing four couplingstrategies for regulating flue gas temperature and waste heat recovery. Agraded flue gas conditioning and waste heat recovery plan was presentedunder the condition of ensuring high desulfurization efficiency, along withthe notion of minimizing energy loss owing to energy inflow temperaturedifference. Numerical results show that the proposed methods improved thesystem performance and reduced the water consumption and regulated theboiler temperature.

The technology of reconfigurable optical networks (RONs) is growing to be a promising solution to effectively cater to the rapidly increasing traffic generated by the digital society. Optical technology emerges as a viable alternative because to its capacity to offer a substantial bandwidth, little latency, and enhanced overall performance. Nevertheless, it is imperative to effectively manage the physical resources comprising a data center. This study provides an experimental demonstration of the RONs, which is enhanced by a control plane. The implementation relies on the monitoring of real-time network statistics. This enables the execution of various activities, including as network slice provisioning and reconfiguration, assignment of packet priority classes, and dynamic operations. These actions are performed to ensure the attainment of the desired Quality of Service level. The experimental results show the successfully implementation of RONs using Mininet Emulator and sFlow traffic monitoring technology. The results approve that optical datacenter has minimum delay with low OSNR even with long distance and fast switching time. © 2023 IEEE.

Neural networks are more commonly used to identify systems for system diagnostics without fully implementing and building the system. The project aims to design and implement the neural network identification system and implement it based on a Field Programmable Gate Array (FPGA) by interfacing between MATLAB / Simulink and Xilinx programs. The work was done thanks to God through two methods: The first through the simulation method through the coupling between MATLAB and Xilinx. While the second method was practically done by loading the simulation designs onto the FPGA. Work performance is measured by subtracting the value resulting from the actual system operation of the identification signal system and the simplified system and the difference between the simulation result and practical result. The use of FPGA with system identification in this project gives us a big advantage that simulation results are equal to practical results (difference is zero). © 2024 IEEE.

The pantograph slide contact temperature and wear of contact surface are greatly affected the electric locomotive working condition under the rain. In this paper, a sliding electrical contact roughness surface model with high speed and different current under the rain is established, which effectiveness is verified by the high performance sliding electrical contact experiment system. Then, the correlation between contact temperature, average roughness slope and average roughness height under the rain is researched via the simulation model. The results show that the impact of rainfall on contact temperature is more pronounced than that of contact current. As the average roughness height increases in various rainfall scenarios, the contact temperature initially undergoes a decrease, followed by an increase, and ultimately returns to a decrease. The average roughness slope is negatively correlated with the contact temperature of slide under different rainfall. The above conclusion has great significance for effectively reducing t the temperature experienced by the pantograph slide at the contact interface within the sliding friction pair. © Beijing Paike Culture Commu.

Loose contact, insulation aging, damage and other reasons of electrical circuitry in power supply and distribution system or equipment will lead to the occurrence of arc fault, and arc fault is one of the main causes of electrical fire accidents. Arc fault detection device (AFDD) is a new type of protection device, which can detect the series arc fault in the line. When the series arc fault occurs, the fault current is usually lower than the threshold of the traditional protection device, and it is difficult to achieve timely protection. The research and development of AFDD has reduced the occurrence of fire accidents to a certain extent. The performance of AFDD on the market is uneven, and the detection accuracy of AFDD produced by different companies for different types of loads is different. In this paper, the performances of four AFDDs produced by different companies at home and abroad are compared, and four typical household load combinations are selected to carry out experiments. The experimental results show that AFDD4 without control function has the highest detection accuracy under all load conditions, with an average accuracy of 99.4% and the shortest response time. Among the three AFDDs with control functions, AFDD1 has the best overall performance and the highest average accuracy, reaching 87.2%. © Beijing Paike Culture Commu. Co., Ltd. 2024.
