For scanning-free liDAR, in the work of long-range non-cooperative target, 3D imaging and detection, the number of echo photons falling on the pixel of detector array is small because the echo is relatively weak. Therefore, on the basis of understanding the current research status of detection technology and system in recent years, combined with the principle of laser heterodyne detection and the statistical principle of photon counting detection, this paper constructed a system ranging accuracy model, and studied the signal-to-noise ratio of photon pulse heterodyne detection system by using random phase-amplitude vector theory. Finally, a photon pulse heterodyne detection system which combines photon technology detection module and pulsed laser heterodyne detection module is obtained.","PeriodicalId":202840,"journal":{"name":"International Conference on Mathematics, Modeling and Computer Science","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123437909","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}

Virtual energy hubs can connect multiple isolated energy hubs and expand the scale of energy Internet. However, the problem of optimal allocation of multiple energy sources considering uncertainty remains to be solved. This paper presents a stochastic programming method for device capacity and topology of multi-zone energy Internet. Firstly, based on the virtual energy hub, the integrated energy system with multi-area interconnection is modeled. Then, based on the extended energy transfer model and mixed power flow model, a multi-energy network association model considering virtual energy hub is established. A two-layer stochastic optimization algorithm for path planning is proposed. The outer layer determines the energy network candidate set, and the inner layer determines the cost optimal device capacity under uncertain scenarios. The simulation results show that the proposed method can give the installed capacity and topology structure of multi-area energy Internet, and the proposed planning algorithm greatly improves the planning efficiency. The relevant planning results are helpful to improve energy efficiency, reduce carbon emission, and improve the economic benefits of energy Internet.","PeriodicalId":202840,"journal":{"name":"International Conference on Mathematics, Modeling and Computer Science","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122294187","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}

Methods A total of 476 brain CT images of patients with spontaneous intracerebral hemorrhage were retrospectively included. The improved Unet network was used to identify and segment the hemorrhagic areas of the patients' brain CT images. Clinicians manually marked the image data of the hemorrhagic areas. 430 pieces of data from 106 patients were selected to enter the training set, and 46 pieces of data from 11 patients were entered into the test set. After the experimental data set was enhanced by data, it underwent network training and model testing to determine the virus cell spreading performance, and segmented the results. Comparison with Unet network, FCN-8s and Unet++ network. Results In the segmentation of the hemorrhagic region of brain CT images by the improved Unet network, the three evaluation indexes of similarity coefficient, forward prediction coefficient and sensitivity coefficient reached 0.8738, 0.901 1 and 0.864 8 respectively, which were improved respectively compared with FCN-8s network. 8.80%, 7.14% and 8.96%, which are 4.56%, 4.44% and 4.15% higher than the Unet network respectively.","PeriodicalId":202840,"journal":{"name":"International Conference on Mathematics, Modeling and Computer Science","volume":"72 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133136205","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}
