The development of cloud platform and Internet of things technology has brought revolutionary impact on enterprise management mode, methods and means. Based on information reconstruction model and Internet of things technology, this paper constructs an enterprise integrated management system, in order to provide reference for the development of enterprises. Novelty of the paper is: (1) Infrastructure level. The comprehensive management informatization is very important to the enterprise management decision-making, which is the key to improve the management level of the enterprise, hence, we use the novel MIS model to make the system efficient. We improve the traditional MIS model to make it fit for the business analytic process. (2) Algorithm design level. The traditional genetic algorithm will converge to a point in the iterative solution, resulting in inbreeding and destroying the diversity of the population. Therefore, the algorithm can only get the internal optimal value and cannot get the global optimal solution. Hence, we consider the novel data analytic model to make the system efficient. We optimize the traditional GA to make it robust for the complex data scenarios. (3) Application level. The business intelligence scenario is considered as the applications.

Since the Y-axis is used to locate the micron-level cutting street, its servo positioning accuracy is required to be very high. In this paper, a variable forgetting factor fuzzy iterative learning control (VFF-FILC) with tracking differentiator is proposed for the high-precision localization of the Y-axis electromechanical servo system of the dual-axis wheel dicing saw model 8230 manufactured by Advanced Dicing Technologies. The method combines fuzzy control with iterative learning control to overcome the problem of poor anti-interference ability of traditional PID control. VFF-FILC reduces the overshoot and build-up time, and also improves the tracking performance by adaptively adjusting the learning rate of the ILC algorithm according to the tracking error of the system. To address the problem of noise interference with the Y-axis servo system, tracking differentiator is used to process the input position signal. In order to verify the superiority of the proposed design, it is compared with three conventional controllers in MATLAB/SIMULINK platform and anti-interference experiments are conducted. The results show that the VFF-FILC reduces the rise time by 28.57% and the overshoot by 88.23% compared to the PID controller, which proves the superiority of the proposed method in the Y-axis servo system of the wheel dicing saw.</p>","PeriodicalId":14463,"journal":{"name":"International Journal of System Assurance Engineering and Management","volume":"19 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140568840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Leveraging MDS for summarizing learning materials opens new avenues, offering students and teachers reference summaries for enhanced learning experiences. This paper introduces a concept-based Integer Linear Programming model for summarizing learning materials, leveraging a phrase embedding technique. Phrases are treated as fundamental and significant semantic building blocks of sentences, facilitating the comprehension and summarization of documents. Embedding techniques are employed to semantically identify related phrases, eliminate redundancy, and enhance coherence through vector representations. Summaries are generated using the ILP technique, selecting key sentences and reducing redundancy with phrase vectors. The paper proposes sentence reordering techniques based on phrases and sentences to further enhance coherence.

The clandestine tactics employed by malicious actors demand innovative solutions that transcend conventional approaches. In this context, this research present a groundbreaking research endeavor that redefines the frontiers of obfuscated malware detection using artificial intelligence. In this research, a comprehensive methodology is introduced that combines three pivotal feature selection techniques: correlation analysis, mutual information, and principal component analysis. This hybrid approach not only enhances the discrimination of meaningful features but also ensures the efficiency and effectiveness of the feature subset, thus mitigating the curse of dimensionality. To harness the full potential of these meticulously selected features, an array of ensemble-based machine learning algorithms, including AdaBoost, stacking, random forest, bagging, and voting, is deployed. Amongst these, our findings demonstrate that AdaBoost emerges as the preeminent choice, achieving unprecedented levels of performance. The outcomes underscore the profound impact of our research in the realm of obfuscated malware detection, a paradigm shift that reimagines the very essence of security.

However, devising an effective charging scheduling schemefor attaining optimal energy consumption still prevails as a complicated problem, particularly while considering the synchronized behavior of both charging stations as well as EVs. Here, a robust QoS-based charge scheduling approach was developed, which exploits the vehicular Adhoc networks (VANETs) with the improved functionalities for enabling communication between the vehicle-traffic server, road-side units (RSUs), and various EVs on roads. An optimal routing is performed by the Fractional-social sky driver (Fractional SSD), which is devised by the incorporation of the Fractional calculus (FC) and social sky driver (SSD) optimization. Here, the multi-objectives, namely, distance, battery power, and predicted traffic density are considered where the traffic density is effectively predicted using deep recurrent neural network (Deep RNN). Then, the charge scheduling process is executed by the utilization of the developed optimization technique called Fractional-social water cycle algorithm (Fractional SWCA)-based scheduling algorithm by taking into account the QoS-based fitness objective, likepriority, response time, and latency. Moreover, the proposed Fractional SWCA is developed by the integration of fractional SSD and water cycle algorithm (WCA).
