These ratios make it possible to model statistical mean of electronic parameters components (and in general, physical characteristics, on the basis of which sensor devices for generation and processing of selective information are designed) with partial distributions, such as Mersenne, Pella, Jacobstall distribution. The mean and variance of discrete random recurrence numbers are determined in the case $pgeq 1, qgeq 1$. It is shown that the mean and variance overestimate only on the parameters $p,q$ in the limit $nrightarrowinfty$. The practical implications of the research carried out consist in the possibility of calculating statistical parameters based on the formulas obtained in the article using other standard numbers of Mersenne, Jakobstal and Pella. In particular, for the number of Pella, the mean is equal to 1.71, variance is equal to 1.21 and mean square error (mse) is equal to 1.1. For the Jacobsthall numbers the mean is equal to 2, variance is equal to 2 and mse is equal to square root 2. For the Mersenne numbers the mean is equal to 1.4, variance is equal to 0.54 and mse is equal to square root 0.745.","PeriodicalId":196129,"journal":{"name":"2023 17th International Conference on the Experience of Designing and Application of CAD Systems (CADSM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129874333","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}

The main task of 5G-U is to operate in the highly congested 5 GHz bands while ensuring harmonious coexistence with other wireless technologies such as Wi-Fi. For this reason, we propose a method of adaptive use of unlicensed spectrum by Wi-Fi and 5G-U networks to ensure the required quality of service (QoS) and fair coexistence. Based on the users' QoS requirements, this method centrally takes reasonable decisions concerning the part of unlicensed radio resource use by 5G-U mobile operators, which allows increasing spectral efficiency in the integrated 5G-U networks with the avoidance of inter-system interference. Simulation results show that the proposed approach, unlike the traditional CSAT (Carrier Sensing Adaptive Transmission) for LTE-U, allocates throughput according to the QoS requirements of users for both Wi-Fi and 5G-U networks. A modified packet queue management algorithm at the data link layer is developed to overcome the consequences of short-term channel failures (interference, low signal strength). This algorithm can occur in Wi-Fi networks under conditions of mass 5G-U deployment. As a result of the simulation, it is proved that the proposed algorithm improved the quality of the video image from 5% to 45% according to the MSE (Mean Squared Error) criterion in the integrated 5G-U/Wi-Fi network.","PeriodicalId":196129,"journal":{"name":"2023 17th International Conference on the Experience of Designing and Application of CAD Systems (CADSM)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121295798","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}

At present, in clinical practice, the analysis and diagnosis of fundus retinal photos are mainly carried out by professional doctors, but this process is very dependent on the clinical experience of doctors, which is time-consuming and labor-intensive, misdiagnosis. Based on this, this paper proposes a DR automatic classification method that integrates attention mechanism and EfficientNet to improve the accuracy of classification and discrimination. In view of the problems in the DR data set, processing such as elimination, amplification and normalization is performed; The attention mechanism is integrated into the EfficientNet network, the DR data set is used to learn and train the improved EfficientNet., and the features are extracted. At the same time, the hole convolution is added to increase the receptive field, and the DR images are divided into 5 categories according to their levels. The method proposed in this paper achieves good results in the DR image classification task, with accuracy, precision, sensitivity and F1 score of 0.857, 0.838, 0.886 and 0.767, respectively. The results show that the DR classification algorithm proposed in this paper has good classification performance.","PeriodicalId":196129,"journal":{"name":"2023 17th International Conference on the Experience of Designing and Application of CAD Systems (CADSM)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125072248","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}
