In recent years, with the development of the Internet of Vehicles, a variety of novel in-vehicle application devices have surfaced, exhibiting increasingly stringent requirements for time delay. Vehicular edge networks (VEN) can fully use network edge devices, such as roadside units (RSUs), for collaborative processing, which can effectively reduce latency. In recent years, with the development of the field of internet of vehicles, a variety of novel in-vehicle application devices have surfaced, exhibiting increasingly stringent requirements for time delay. Vehicular edge network (VEN) can make full use of network edge devices, such as road side unit (RSU) for collaborative processing, which can effectively reduce the latency. Most extant studies, including patents, assume that RSU has sufficient computing resources to provide unlimited services. But in fact, its computing resources will be limited with the increase in processing tasks, which will restrict the delay-sensitive vehicular applications. To solve this problem, a vehicle-to-vehicle computing task offloading method based on deep reinforcement learning is proposed in this paper, which fully considers the remaining available computational resources of neighboring vehicles to minimize the total task processing latency and enhance the offloading success rate. A vehicle-to-vehicle computing task offloading method based on deep reinforce-ment learning is proposed in this paper, which fully considers the remaining available computa-tional resources of neighboring vehicles with the objective of minimizing the total task processing latency and enhancing the offloading success rate. In the multi-service vehicle scenario, the analytic hierarchy process (AHP) was first used to prioritize the computing tasks of user vehicles. Next, an improved sequence-to-sequence (Seq2Seq) computing task scheduling model combined with an attention mechanism was designed, and the model was trained by an actor-critic (AC) reinforcement learning algorithm with the optimization goal of reducing the processing delay of computing tasks and improving the success rate of offloading. A task offloading strategy optimization model based on AHP-AC was obtained on this basis. The average latency and execution success rate are used as performance metrics to compare the proposed method with three other task offloading methods: only-local processing, greedy strategy- based algorithm, and random algorithm. In addition, experimental validation in terms of CPU frequency and the number of SVs is carried out to demonstrate the excellent generalization ability of the proposed method.

To improve the accuracy of Chinese word splitting. With the development of Internet technology, people want to get some effective medical information from the Internet, but there are still technical difficulties for non-specialists. At the same time, the level of medical construction can not keep up with the demand of patients for medical treatment, the phenomenon of doctor-patient conflicts has not been fundamentally solved, and the problem of difficult consultation prevails. With the arrival of the era of big data and artificial intelligence, medical Q&A has been applied. In order to meet the user's need to get the correct answer as soon as possible, medical Q&A needs to have high execution efficiency. The accuracy of Chinese participle directly affects the execution efficiency of Q&A. Improving the accuracy of Chinese participle can fundamentally improve the accuracy of medical Q&A and shorten the answering time. Improvement of the Chinese Segmentation Algorithm based on BI-LSTM-CRF using natural language processing technology. Based on the same medical Q&A dataset, the medical Q&A is trained and tested under three commonly used segmentation algorithms and the segmentation algorithm designed in this paper. The experiments show that the Chinese Segmentation Algorithm studied in this paper improves the accuracy of medical Q&A and can improve the execution efficiency of medical Q&A. Based on the calculation and matching process of the same similar answers, different word-splitting methods directly affect the effect of medical Q&A in the later stage. The better the effect of segmentation, the higher the accuracy of the correct answers in medical Q&A. The improved LSTM-CRF split word accuracy designed in this paper achieves a good split word effect in the training process. Compared with the HMM segmentation algorithm, which has the best segmentation performance among the other three algorithms, the segmentation accuracy is improved, and the accuracy of the Q&A that delivers the correct answers is relatively high. Despite the improved accuracy in segmenting the medical dataset, the time complexity did not decrease much. The LSTMCRF combined network segmentation algorithm designed in this paper performs better in medical Q&A compared to other commonly used segmentation algorithms in terms of subject operating characteristics and larger regions surrounded by coordinate axes.

The increasing demand for electricity, coupled with an imbalanced supply and demand, population growth, and climate change, has prompted the shift from conventional to non-conventional energy systems. However, the unreliability and intermittency of the latter pose a challenge to their feasibility. To address this challenge, a proposal has been made to explore the combination of two renewable energy sources (RES) using a unique DC-DC converter topology, with the aim of meeting the load demand in a sustainable and efficient manner. The focus of this research was to explore solutions for the challenges associated with operating RES independently, including issues with intermittency, weather dependence, and meeting load demands. The proposed hybrid system features exclusively RES, offering a promising approach to reducing carbon footprint. Ultimately, we aimed to develop a CUK-SEPIC-based converter that can effectively integrate two independent RES to satisfy the load demand of a standalone application. Effective hybrid power generation through RES is a complex challenge, but it has been found that combining solar and biomass energy sources is one of the best options for achieving this goal. To tap into these sources, it is essential to have a suitable power electronic converter, and the CUK-SEPIC converter has been chosen for its many benefits. The features of this converter have been described in detail. The integration of solar and biomass energy sources is achieved using this converter, which has been designed and mathematically modeled in the MATLAB/Simulink environment to ensure optimal performance. To validate the effectiveness of the proposed converter, a comparison with existing power electronic converters has been done using the MATLAB/Simulink platform. The hybrid power generation system model has been comprehensively developed in this work using the sophisticated MATLAB/Simulink environment. The input and output parameters have been diligently estimated through an extensive simulation process. The research has yielded valuable insights, indicating that the CUK-SEPIC converter exhibits an impressive power conversion efficiency of 96.57%, along with an overall step-up ratio of 5.25 and significantly reduced ripple content. Upon conducting a comprehensive analysis of the CUK-SEPIC DC-DC converter, it has been observed that the proposed system exhibits significant promise in rectifying the reliability issues commonly associated with renewable energy power generation. Therefore, it is recommended that this system be considered for implementation in rural electrification initiatives. Furthermore, it is worth noting that this system represents one of the most recent developments in the field of renewable energy power generation technology.

Development of ionic membranes by using generic polymers polyvinyl alcohol (PVA) and Polystyrene sulfonic acid (PSSA), which have been implemented as sensing devices. Our health is directly influenced by wearable sensors therefore, we need to enhance its quality. Wearable sensors depend on the sensitivity of the material as well as the phase transition of ions. The phase transition of ion/charge is analyzed through percolation theory, which is based on the probability model. Percolation displays what are referred to as crucial phenomena. This typically indicates that the model contains a natural parameter at which the system's behaviour substantially alters. The PVA/PSSA(S2) membrane of 25% composition reveals the minimum percolation threshold of 0.20. Sample S1(10%), S2(25%), and S3(45%) possess phase transitions of 0.525,0.225, and 0.0343, respectively. The robustness of the phase transitions and the sensitivity were examined using the percolation theory. Out of five samples, the three samples have more feasible coordinates for building wearable sensors, which are sample S1(10%), S2(25%), and S3(45%). The analysis of the pure PSSA polymer research is expected to be done in the upcoming months in order for a patent.

Musculoskeletal disorders (MSDs) are a group of non-fatal injuries that can occur as a result of various repetitive workplace activities, mainly in unorganized sectors. Workers who engage in highly repetitive activities involving constant hand effort, localized mechanical pressure, and vibration are more prone to developing these disorders. The objective of this research was to determine the prevalence of MSDs among workers in various unorganized sectors in India who perform hand-intensive occupations. The purpose of current research was to determine the MSD prevalence among workers in various unorganized sectors of India, who perform a severe hand–intensive occupations. A cross-sectional study was conducted, involving 340 workers from diverse groups such as sugarcane farmers, footwear industry workers, and tarpaulin weavers, to accomplish this goal. Data for the survey was collected using a questionnaire. Additionally, a comprehensive time study and a deep learning-based posture detection study were conducted on the different activities performed during the workers' occupational tasks. The chi-square test was used to assess the relationship between discomfort and work repetitiveness. The data analysis revealed that the working activities (especially cutting/harvesting, rubber cutting, etc.) of unorganized sector workers were repetitive, with more than half of each activity’s work cycle involving a similar usage pattern. Furthermore, a significant association was observed between the level of discomfort and work repetitiveness among workers in different sectors (sugarcane farmers: p <0.01, footwear industry workers: p < 0.05, tarpaulin weavers: p < 0.05). Consequently, it can be concluded that prolonged occupational activities involving repetitive and prolonged standing may contribute to the occurrence of MSDs. As per the data analysis, all activities were repetitive with over half of each activity's work cycle involving a similar usage pattern. As a result, it can be stated that prolonged occupational activity in repetitive and prolonged standing mode may be considered contributory factors in the MSDs occurrence. Ergonomic interventions/modifications in the form of patent work will be necessary to prevent these issues in the near future.
