Unit 1 and unit 2 of a company tripped because the root switches of two units were connected. Due to the "BYPASS" function in the industrial intrusion detection system in the safety protection system, when the "BYPASS" function is activated in the state of power loss, the two network interfaces (No. 1 and No. 2) on the industrial intrusion detection system are physically connected, and the security switch in the safety protection system of unit 2 is not configured. At this time, the whole safety protection system becomes a conduction loop, the root switch of the DCS system of unit 1 and unit 2 is connected, and the SID address of some parameters in the DCS system of the two units is the same, resulting in data conflict in the DCS system of unit 1 and unit 2. As a result, the 0/1 state of switch measurement point of Unit 1 "backpressure overlimit jumper 1", "backpressure overlimit jumper 2" and Unit 2 "backpressure overlimit jumper 1" are flipped. Error signal command is issued, unit 1 and 2 trip out of column.

In OpenFlow networks, the controller configures the forwarding of packets and gets states and statistics of the network from operating on flow entries in flow tables of *** centralized controlling brings such a problem. If flow entries matching a wide range of packets is installed, the controller cannot get statistics of precise flows. If flow entries to match a precise range are used, lots of misses are happened, which invokes the controller frequently and affects the performance of packet forwarding. In this paper, we propose and implement a new Open Flow action: flow-split to solve this problem. This action can generate new flow entries in the switch according to its configurations and the header fields of the matched packets. By installing flows using flow-split action that match a wide range,the controller can still get the statistics of more precise flows from the generated precise flow entries, and reduce the invoking of the controller. Experiments on emulated networks shows that flow entries with flow-split action achieves a significant reduction on flow establish time and involvement of the controller.

Dunhuang mural images classification belongs to the research task in the field of image recognition. In this paper, the semi-supervised model is established with multidimensional features extracted by transfer learning. A small number of labeled samples were used to obtain a large number of unlabeled data, combined with Active Learning and iterative strategy for multiple rounds of label transfer of selected samples. After several rounds of iterations, we can get a more powerful classification learner. Experiments on the self-built Dunhuang mural dataset have shown that the results can approach or even exceed some supervised learning methods when the number of known label samples is less than 4%. Our research implements the cultural resource image classification algorithm based on small samples, which is conductive to improving the accuracy when label samples are scarce.

Based on the graph model algorithm, this paper proposes a management method for microservices to split the branch dependency relationship into no branch dependency relationship. Topological relationship is searched through the pointer of the index-free adjacent graph database, and the dependency edge is represented by nodes in the graph model to distinguish the position of the algorithm module in different task processes. The algorithm module that is multiplexed by multiple tasks is represented by only one algorithm module node in the graph, and finally it has obvious advantages through experiment.

In the current agricultural intelligence, the monitoring of plant growth environment parameters needs to use a variety of sensors which also leads to the existing intelligent control system being generally large. The electrical signal is another important signal in plants which contains abundant information besides hydraulic and chemical signals. Plant electrical signals can not only regulate plant growth but also reflect the environment to a certain extent. The collection of Aloe Vera electric signals at different temperatures (15, 19, 23, 27, 31, and 35 ℃) is accomplished by using LabVIEW software and hardware. The signal is denoised by using the module in the signal processing toolkit. The BP network is trained repeatedly by extracting the eigenvalues from the signal and the model with the smallest mean variance is selected as the optimal model. Deploy the model to the computer and use mixed programming with MATLAB to invoke the model. Use the powerful graphical programming and interface development capabilities of LabVIEW to ultimately build a monitoring system for plant growth environment temperature. Making the future agricultural intelligent control system lightweight and portable.

The transformation of operators' traffic management, the demand for refined management, and the improvement of users' satisfaction have put forward higher requirements for network maintenance. In order to better network fine operation and maintenance management around user perception, this paper analyzes the influence of quality of service (QoS) and quality of experience (QoE) on users' subjective feelings, establishes an evaluation model to quantify user experience quality, and lists a practical application scenario using this model.

This paper describes the performance evaluation of an SIMD system on a commonly encountered Standard Linear Equation problem. We introduce a prototype SIMD system, called the Systola 1024, whose parallel architecture is based upon the Instruction Systolic Array concept. To evaluate the performance of this architecture we have implemented an in-cache problem to measure its MFLOP by solving the Gaussian Elimination problem to obtain the LU factorization. We also examine the effects of increasing the array processors by a certain factor.
