In today’s world, advanced internet technologies have significantly increased people’s affinity towards social networks to stay updated on current events and communicate with others residing in different cities. Social opinion analyses helped determine the optimal public health response during the COVID-19 pandemic. Analysis of articulating tweets from Twitter can reveal the public’s perceptions of social distance. Sentiment Analysis is used for classifying text data and analyzing people’s emotions. The proposed work uses LSTM-RNN with the SMOTE method for categorizing Twitter data. The suggested approach uses increased characteristics weighted by attention layers and an LSTM-RNN-based network as its foundation. This method computes the advantage of an improved information transformation framework through the attention mechanism compared to existing BI-LSTM and LSTM models. A combination of four publicly accessible class labels such as happy, sad, neutral, and angry, is analyzed. The message of tweets is analyzed for polarization and subjectivity using TextBlob, VADER (Valence Aware Dictionary for Sentiment Reasoning), and SentiWordNet. The model has been successfully built and evaluated using two feature extraction methods, TF-IDF (Term Frequency-Inverse Document Frequency) and Bag of Words (BoW). Compared to the previous methodologies, the suggested deep learning model improved considerably in performance measures, including accuracy, precision, and recall. This demonstrates how effective and practical the recommended deep learning strategy is and how simple it is to employ for sentiment categorization of COVID-19 reviews. The proposed method achieves 97% accuracy in classifying the text whereas, among existing Bi-LSTM, achieves 88% maximum in the text classification.

The emergence of the Internet of Things (IoT) accelerated the implementation of various smart city applications and initiatives. The rapid adoption of IoT-powered smart cities is faced by a number of security and privacy challenges that hindered their application in areas such as critical infrastructure. One of the most crucial elements of any smart city is safety. Without the right safeguards, bad actors can quickly exploit weak systems to access networks or sensitive data. Security issues are a big worry for smart cities in addition to safety issues. Smart cities become easy targets for attackers attempting to steal data or disrupt services if they are not adequately protected against cyberthreats like malware or distributed denial-of-service (DDoS) attacks. Therefore, in order to safeguard their systems from potential threats, businesses must employ strong security protocols including encryption, authentication, and access control measures. In order to ensure that their network traffic remains secure, organizations should implement powerful network firewalls and intrusion detection systems (IDS). This article proposes a blockchain-supported hybrid Convolutional Neural Network (CNN) with Kernel Principal Component Analysis (KPCA) to provide privacy and security for smart city users and systems. Blockchain is used to provide trust, and CNN enabled with KPCA is used for classifying threats. The proposed solution comprises three steps, preprocessing, feature selection, and classification. The standard features of the datasets used are converted to a numeric format during the preprocessing stage, and the result is sent to KPCA for feature extraction. Feature extraction reduces the dimensionality of relevant features before it passes the resulting dataset to the CNN to classify and detect malicious activities. Two prominent datasets namely ToN-IoT and BoT-IoT were used to measure the performance of this anticipated method compared to its best rivals in the literature. Experimental evaluation results show an improved performance in terms of threat prediction accuracy, and hence, increased security, privacy, and maintainability of IoT-enabled smart cities.
物联网(IoT)的出现加速了各种智慧城市应用和倡议的实施。物联网驱动的智慧城市的快速采用面临着许多安全和隐私挑战,这些挑战阻碍了它们在关键基础设施等领域的应用。任何智慧城市最重要的因素之一就是安全。如果没有正确的保护措施,不法分子可以迅速利用薄弱的系统访问网络或敏感数据。除了安全问题之外,安全问题也是智慧城市的一大担忧。如果智能城市没有充分防范恶意软件或分布式拒绝服务(DDoS)攻击等网络威胁,就很容易成为攻击者窃取数据或破坏服务的目标。因此,为了保护系统免受潜在威胁,企业必须采用强大的安全协议,包括加密、身份验证和访问控制措施。为了确保他们的网络通信保持安全,组织应该实现强大的网络防火墙和入侵检测系统(IDS)。本文提出了一种区块链支持的混合卷积神经网络(CNN)和核主成分分析(KPCA),为智慧城市用户和系统提供隐私和安全。区块链用于提供信任,CNN启用KPCA用于对威胁进行分类。该方案包括预处理、特征选择和分类三个步骤。在预处理阶段,使用的数据集的标准特征被转换为数字格式,并将结果发送给KPCA进行特征提取。特征提取在将得到的数据集传递给CNN进行分类和检测恶意活动之前,先降低相关特征的维数。两个突出的数据集,即ToN-IoT和BoT-IoT,被用来衡量与文献中最好的竞争对手相比,这种预期方法的性能。实验评估结果表明,在威胁预测精度方面的性能有所提高,从而提高了物联网智能城市的安全性、隐私性和可维护性。

The existing approach for monitoring the insulation state of photoelectric composite submarine cables primarily relies on detecting the current of the cable protection layer. However, this conventional method suffers from limited monitoring accuracy due to the absence of parameter identification processing for the cable. As a result, there is a need to improve the monitoring methodology by incorporating robust parameter identification techniques to enhance the accuracy of insulation state evaluation. In this regard, a real-time monitoring method based on thermoelectric coupling is proposed to monitor the insulation status of the photoelectric composite submarine cable. By constructing an equivalent composite circuit model and a thermodynamic function, a thermoelectric coupling model is constructed and used to identify the parameters of the submarine cable; by extracting the frequency extremes in the spectral values of the submarine cable current signal, an equivalent insulation characteristic function is constructed to realize the determination of the insulation state. The proposed method is verified for the insulation state monitoring effect in the experiment. The experimental results show that when the proposed method is used to monitor the insulation state of the photoelectric composite submarine cable, the calculated partial discharge quantity has a small error, and the monitoring accuracy is high.
现有的光电复合海底电缆绝缘状态监测方法主要依靠对电缆保护层电流的检测。然而,由于没有对电缆进行参数识别处理,这种传统方法的监测精度有限。因此,有必要通过结合鲁棒参数识别技术来改进监测方法,以提高绝缘状态评估的准确性。为此,提出了一种基于热电耦合的光电复合海底电缆绝缘状态实时监测方法。通过建立等效复合电路模型和热力学函数,建立了海底电缆的热电耦合模型并用于参数辨识;通过提取海缆电流信号频谱值中的频率极值,构造等效绝缘特征函数,实现绝缘状态的确定。实验验证了该方法的绝缘状态监测效果。实验结果表明,将该方法用于光电复合海缆绝缘状态监测时,计算的局部放电量误差小,监测精度高。

In the actual operation process of the conventional digital agricultural greenhouse monitoring system, there are problems such as limited monitoring scope and large deviation between the monitoring results and the actual situation of the greenhouse. To solve this problem, a new remote monitoring system is proposed by introducing the technology of the Internet of Things. On the basis of the completion of the hardware design of the remote monitoring system, the optimal fusion data value of the remote monitoring of the digital agricultural greenhouse is obtained by establishing the monitoring data fusion model. The particle swarm optimization fuzzy control algorithm is designed to optimize the adaptive remote monitoring process of the system dynamically. The Internet of Things technology is used to deploy the remote monitoring system of digital agricultural greenhouses online to fully ensure the quality and timeliness of the remote monitoring system. The test results show that the new system can significantly improve the greenhouse remote monitoring deviation, and the monitoring value is close to the actual value.

A visualization and interactive network topology model are studied based on real-time features generated during spaceflight. Start by establishing a consistent set of data and logical interaction interfaces. This paper presents a method of scenario model construction and application programming based on virtual reality technology. The scene elements are extracted into two types of primitives, namely logical type and simulated object type. This provides a unified architecture for the editing and processing of graphic elements. This system can realize the automatic creation of the scene. Then the point cloud data obtained by sparse reconstruction of SFM is reconstructed to the Poisson surface. You get a dense, uniform grid. Experiments show that the proposed algorithm can realize the 3D reconstruction of non-cooperative objects. The spatial feature points obtained in the spatial positioning of non-cooperative objects can provide necessary technical support for its orbit positioning. The model can quickly generate new model scenario pages according to the characteristics of the task. This method changes the display mode, which can only be static or limited dynamic before. It has also improved the efficiency of space mission preparation.

The article addresses the challenges modelled by the inadequacy of traditional detection methods in effectively handling the substantial volume of software behavior samples, particularly in big data. A novel approach is proposed for leveraging big data technology to detect malicious computer code signals. Additionally, it seeks to attack the issues associated with machine learning-based mobile malware detection, namely the presence of a large number of features, low accuracy in detection, and imbalanced data distribution. To resolve these challenges, this paper presents a multifaceted methodology. First, it introduces a feature selection technique based on mean and variance analysis to eliminate irrelevant features hindering classification accuracy. Next, a comprehensive classification method is implemented, utilizing various feature extraction techniques such as principal component analysis (PCA), Kaehunen-Loeve transform (KLT), and independent component analysis (ICA). These techniques collectively contribute to enhancing the Precision of the detection process. Recognizing the issue of unbalanced data distribution among software samples, the study proposes a multi-level classification integration model grounded in decision trees. In response, the research focuses on enhancing accuracy and mitigating the impact of data imbalance through a combination of feature selection, extraction techniques, and a multi-level classification model. The empirical results highlight the effectiveness of the proposed methodologies, showcasing notable accuracy improvements ranging from 3.36% to 6.41% across different detection methods on the Android platform. The introduced malware detection technology, grounded in source code analysis, demonstrates a promising capacity to identify Android malware effectively.

Sentiment analysis has gained increasing attention from an educational and social perspective with the huge expansion of user interactions due to the Web’s significant improvement. The connection between an opinion target’s polarity scores and other aspects of the content is defined by aspect-based sentiment analysis. Identifying aspects and determining their different polarities is quite complicated because they are frequently implicit. To overcome these difficulties, efficient hybrid methods are used in aspect-based text classification in sentiment analysis. The existing process evaluates the aspects of polarity by using a Convolutional neural network, and it does not work with Big data. In this work, aspect-based text classification and attention mechanisms are used to assist in filtering out irrelevant information and quickly locating the essential features in big data. Initially, the data is collected, and then the data is preprocessed by using Tokenization, Stop word removal, Stemming, and Lemmatization. After preprocessing, the features are vectorized and extracted using Bag-of-Words and TF-IDF. Then, the extracted features are given into word embeddings by GloVe and Word2vec. It uses Deep Recurrent based Bidirectional Long Short Term Memory (RUBiLSTM) for aspect-based sentiment analysis. The RU-Bi-LSTM method integrates aspect-based embeddings and an attention mechanism for text classification. The attention mechanism focuses on more crucial aspects and the bidirectional LSTM to maintain context in both ways. Finally, the binary and ternary classification outcomes are obtained using the final dense softmax output layer. The proposed RU-BiLSTM uses four reviews and two Twitter datasets. The results of the studies demonstrate the efficacy of the RU-BiLSTM model, which outperformed aspect-based classifications on lengthy reviews and short tweets in terms of evaluation.
随着网络的显著改进,用户交互的巨大扩展,情感分析从教育和社会的角度得到了越来越多的关注。意见目标的极性得分与内容的其他方面之间的联系是由基于方面的情感分析定义的。识别方面并确定它们的不同极性是相当复杂的,因为它们通常是隐含的。为了克服这些困难,情感分析中基于方面的文本分类采用了高效的混合方法。现有的方法是通过使用卷积神经网络来评估极性的各个方面,而且它不适用于大数据。在这项工作中,使用基于方面的文本分类和注意机制来帮助过滤掉不相关的信息,并快速定位大数据中的基本特征。首先收集数据,然后使用Tokenization、Stop word removal、词干化和词形化对数据进行预处理。预处理后,使用Bag-of-Words和TF-IDF对特征进行矢量化提取。然后,将提取的特征用GloVe和Word2vec进行词嵌入。它使用基于深度循环的双向长短期记忆(RUBiLSTM)进行基于方面的情感分析。RU-Bi-LSTM方法集成了基于方面的嵌入和文本分类的注意机制。注意机制关注更关键的方面,双向LSTM在两种方式下维持语境。最后,利用最终的密集softmax输出层得到二值和三值分类结果。提出的RU-BiLSTM使用四个评论和两个Twitter数据集。研究结果证明了RU-BiLSTM模型的有效性,在评估方面优于基于方面的分类,在长评论和短推文中。

The main dynamic truck routing problem also presents a significant difficulty in the logistics sector, which is an unavoidable development trend of the contemporary technological changing society. A dynamic vehicle routing problem with time window model is suggested by the study in order to establish an effective and low-energy dynamic response method. The fundamental concept is to disrupt the conventional strategy of static dynamic consumers responding in time slots by dividing the dynamic time window into a static time window with several time slice intervals. The study makes use of cutting-edge ideas including dynamic attitude, before-and-after time slicing, and continuous optimisation while proposing a new method for model solution to optimise dynamic vehicle route issues effectively and affordably. The study employs the Solomon optimisation dataset and runs simulation studies on the Java platform to confirm its efficacy. The experimental findings demonstrated that the optimisation technique employed in the study reduced the cost of travelling by 83.8 miles while also considerably increasing the average vehicle utilisation by 3.6%. Because driving distance cost and vehicle number cost are typically positively connected with dynamic attitude, the study employs solutions that can increase dynamic response efficiency and save money. As a result, their robustness is higher.
主要的动态卡车路线问题也是物流领域的一个重大难题,是当今技术变革社会不可避免的发展趋势。为了建立一种有效的、低耗能的动态响应方法,提出了一种带时间窗模型的动态车辆路径问题。其基本概念是通过将动态时间窗口划分为具有多个时间片间隔的静态时间窗口来打破静态动态消费者在时隙响应的传统策略。该研究利用动态姿态、前后时间切片、连续优化等前沿思想,提出了一种新的模型求解方法,有效且经济地优化动态车辆路径问题。该研究采用了Solomon优化数据集,并在Java平台上进行了模拟研究,以证实其有效性。实验结果表明,研究中采用的优化技术减少了83.8英里的旅行成本,同时也大大提高了3.6%的平均车辆利用率。由于行驶距离成本和车辆数量成本与动态态度呈正相关,本研究采用了既能提高动态响应效率又能节省资金的解决方案。因此,它们的稳健性更高。

Conventional online composite submarine cable monitoring data release mostly adopts the method and principle of blockchain dynamic zoning consensus. In the data release process, there are omissions, and it takes a long time to complete the task, which reduces the timeliness of online composite submarine cable monitoring data release. Based on this, a new data publishing method is proposed by introducing horizontal federation learning. First, the online monitoring data of composite submarine cables are collected and preprocessed to eliminate the high-frequency capacitive effect of submarine cables. Secondly, manage composite submarine cable data nodes, transform the status relationship of data nodes, and ensure the quality of subsequent data release. A horizontal federation learning model is established to design the online monitoring data release process. The experimental results show that the new data release method is highly feasible. With the increasing online monitoring data of composite submarine cables, the time required for data release is short, and the timeliness is high.
