However, while having capabilities to extract more contextual information, these detectors also capture redundant information, which will reduce the precision of detection. In this paper, we propose a novel and lightweight block based on spatial attention mechanism to solve this problem effectively. Compared with RFB, it can better capture effective contextual information in the feature map and suppress redundant information. Moreover, we propose a local enhancement strategy, which can sparsely locate regions that contains rich feature information and enhance them locally. Experimental results show that our proposed method gains 0.6% mAP improvement on the PSACAL VOC dataset and 0.5% mAP improvement on the COC02019 test-dev set.","PeriodicalId":6712,"journal":{"name":"2020 5th International Conference on Mechanical, Control and Computer Engineering (ICMCCE)","volume":"37 1","pages":"1655-1658"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84775093","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}

However, for the sake of security, important confidential units still disable all networks and use USB to transmit files, which wastes a lot of human resources and personnel energy. This paper constructs a small Zero Trust network model based on Elastic Stack, aiming to try to solve the problem of no network availability for important confidential units, and provide a method for solving the hidden danger of leakage. This model uses fingerprint as the user login credentials, and maps all operations to people accurately. Beats components running on the computer can collect and audit information such as user operation records. The information will be sent to Elasticsearch(ES), which will also be monitored by Kibana analysis. Users will be recorded and alerted if they overstep their authority or violate the rules. The security concept and effect of Zero-Trust network are very consistent with the work requirements of important confidential units. This paper proposed that important confidential units should try to build a zero-trust network, and use the network to improve work efficiency while ensuring confidentiality.","PeriodicalId":6712,"journal":{"name":"2020 5th International Conference on Mechanical, Control and Computer Engineering (ICMCCE)","volume":"34 1","pages":"1075-1078"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90557641","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}

This trajectory optimization method provides results of both morphing strategy and state variables regarding aerodynamic advantages of different aircraft geometries. And a traditional controller is designed to track the optimized trajectory during the entire morphing process.

In order to ensure a safe and stable operating environment for the equipment, it is necessary to inspect the computer room. The traditional manual inspection method has the disadvantages of low efficiency, poor quality, high cost and power consumption. In this paper, a kind of inspection robot is proposed, which can replace human to complete inspection task, so as to reduce cost and improve the reliability of inspection work. The robot chassis has omnidirectional movement feature in structure. In functionally, the robot adopts temperature humidity sensors DHT11, gas pressure sensor BMP180 and smoke sensor MQ-2 to inspection computer room environment. Furthermore, kinematics analysis and MATLAB simulation were carried out on the omnidirectional mobile chassis of the robot; the environmental detection function of the robot was tested by experiment. The results show that the robot can realize omnidirectional mobile and environment detection function.","PeriodicalId":6712,"journal":{"name":"2020 5th International Conference on Mechanical, Control and Computer Engineering (ICMCCE)","volume":"161 1","pages":"951-956"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80635545","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}

Firstly, the principle of repulsion mechanism and magnetic mechanism is introduced in this paper.

The dynamic characteristics of the mechanism are simulated and analyzed, and the corresponding optimal parameters are obtained. Finally, the action speed, the output force and the control circuit current of the repulsion mechanism and magnetic mechanism are compared. The simulation results show that the initial output of the repulsion mechanism is too large and the later output is insufficient, while the driving current of the magnetic mechanism is moderate and the output is uniform, so the magnetic mechanism is more suitable for long stroke bypass switch.","PeriodicalId":6712,"journal":{"name":"2020 5th International Conference on Mechanical, Control and Computer Engineering (ICMCCE)","volume":"3 1","pages":"438-441"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83642443","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}

Event detection is the first step of the event extraction task, which plays a decisive role in the subsequent event extraction work. The article adopts BERT for word vector training, joint lexical vector, named entity vector, and semantic dependency vector as the input of Bi-LSTM, and then input them into the CRF sequence tagging layer after acquiring the features of sentences to achieve the recognition of event trigger words and the classification of event categories.

It is deployed as heterogeneous accelerators on a large scale in cloud computing centers and research laboratories. Usually., developers operate directly on the physical machines and use the FPGA card exclusively. This leads to a bad utilization of FPGA resources. This paper proposes to virtualize and deploy FPGA resources as lightweight containers by using Docker and Kubernetes together. The Docker containers abstract FPGA resources and provide an isolated runtime environment for each application. The Kubernetes performs unified and automated scaling and scheduling of virtualized FPGA containers. Thus, FPGA resources can be safely and effectively shared among multiple local and remote applications. Experiments show that the utilization of FPGA resources has been improved.","PeriodicalId":6712,"journal":{"name":"2020 5th International Conference on Mechanical, Control and Computer Engineering (ICMCCE)","volume":"106 5 1","pages":"473-476"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89737908","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}
