This paper proposes an application anomaly detection and bottleneck identification system (AAD-PSC) based on cloud platform service components. The system can monitor and analyze applications on multi-layered cloud platforms with customized index values. The embedded Ethernet interface is composed of MCU and Ethernet control chip W5500. The three-layer architecture of "cloud server, device, sensor and controller" is adopted to realize no difference monitoring at any time, place and terminal. The monitoring module dynamically adjusts the sampling period so that the sampling points are concentrated in the period when the resource usage of the application system fluctuates greatly. Use UDP/IP protocol to exchange information between the local and the cloud, and analyze and process the data in the cloud. The test results show that the system has the characteristics of low cost, small size, low power consumption and high data transmission accuracy.

In order to properly control rabbles, we shall investigate computervision and mechanical aid technologies with lending devices here. Machine intelligence, commonly referred to as AI, or algorithms, enables software to improve prediction performance while requiring a deliberate goal to do so. Machine-learning algorithms anticipate new output using historical data as their input. Since information is so crucial, creating novel approaches for effectively administering the neighbourhood, pervasive data gathering systems of today is a crucial next stage for actors and thus is entirely independent. Therefore, deep learning and its autonomous rabbel control support network will be discussed here. With the availability of information expanding through time, education for application in numerous sectors has become more widespread. Many fields have benefited from the use of machine vision, encompassing research and academia database and process visualisation, biomedical imaging, and more. These methods have been applied to safety, computer components, internet websites, and mobile applications. Thus, we can draw an opinion regarding an autonomous assistance system for effective kernel maintenance that is based upon deep ***, COVID-19 is causing mayhem throughout the world.

This paper builds a portable digital ion trap mass spectrometer prototype by designing the vacuum system, control circuit system, and host computer of the ion trap mass spectrometer. Dextromethorphan and ketamine samples were tested. At a scanning rate of 5000Th/s, the resolution of the dextromethorphan sample reached 0.26Th, and the resolution of the ketamine sample reached 0.33Th. The actual mass spectrum collected by the prototype is basically consistent with the theoretical mass spectrum.

The detection of weeds is an essential component of precision agriculture because it provides farmers with the tools necessary to efficiently manage and control weed infestation in agricultural areas. Manual work is laborious and error-prone in traditional weed-detecting methods. computervision and machine learning have shown promise in automating weed detection in recent years. This study introduces a hybrid model that combines AdaBoost and CNN to detect weeds. The hybrid model uses AdaBoost and CNN to boost weed detection accuracy. AdaBoost is used as a feature selector to identify input images with discriminative properties. CNNs, or convolutional neural networks, are popular deep learning models that can extract complex spatial features from images. This CNN receives the selected features. The CNN learns and improves features, enabling precise weed classification. A large dataset from Kaggle with crop field images of various weed species and backdrops is used to evaluate the hybrid model. The dataset is hand-annotated to provide ground truth labels for training and testing. The dataset trains the hybrid model, which is optimized for precision, recall, and F1 score. Experimental comparisons show that the proposed AdaBoost and CNN hybrid model outperforms individual models and other weed detection methods in accuracy and computing economy.

Understanding how measurement noise influences sloshing dynamics is required to comprehend how it affects space vehicles in proximity operations. Despite researchers’ interest in space vehicle dynamics in proximity operations, few studies have explored the implications of measurement noise on its dynamics. However, one key problem encountered is poor estimation of the system state variable, which leads to poor control of the system. As a result, this study attempts to solve this issue by offering a scheme for providing critical information on the optimal estimation of the unmeasured states of the fuel sloshing dynamics. The approach was primarily based on moving horizon estimator-based model predictive control. The results obtained demonstrated the efficiency of the moving-horizon estimator in estimating unmeasured state variables. Hence, when the effects of measurement noise are considered, the moving horizon estimator provides a good assessment of the unmeasured states in a proximity operation.

The Receiver Operator Characteristic (ROC) test is often used to evaluate classification performance. However, it calls for special consideration when applied to the class-imbalanced data. The Precision-Recall Curve (PRC) is dependent on the class imbalance ratio. It summarizes the trade-off between the true positive rate and the positive predictive value for a predictive model using different probability thresholds. In this work, PRC is used to enhance the precision and recall of the Classification And Regression Tree (CART) algorithm to diagnose breast cancer; this enhanced the CART recall’s capacity to predict wrongly classified samples by 10%, from 89% to 99%, when compared to the standard CART algorithm. On the other hand, when evaluating the performance of the improved CART on unseen data, it achieved a recall of 95%. Thus, the recall of the CART decreased by 4% from 99% to 95%. This drawback can be attributed to the small size of the training data, which has been labeled using one of the clustering methods, spectral clustering, which achieved the best Silhouette in separating data into two clustering with a score of 0.43.

With the rapid development of the national economy, the number of substations and the amount of substation information have doubled, but the monitoring information table of the station monitoring system, gateway computer, centralized control system and PMS3.0 management module has not yet established the functions of automatic verification, exception reminder and centralized management. There is a lack of automatic support means for the standardization and integrity verification of the information point table, and there are risks in the integrity and correctness of the monitoring information, It is not conducive to the daily work of equipment management discipline. Therefore, relying on the overall architecture of PMS3.0 and centralized control system, in accordance with the basic principle of "multi-level application and data penetration", through technical means and management methods, we can realize the automatic verification of the consistency of "four tables", strengthen the standardized management of the whole process, and improve the intrinsic safety of substation operation and maintenance monitoring.
