The economic efficiency of “virtual” consumption in the tourism industry is substantiated referring to the contemporary profile of a common traveller, namely during the period of economic recession (as proved by the statistics of international tourism indicators – the number of visits, the GDP impact and employment rates). The statistics of browsers' use worldwide and in Ukraine is given; the advantages of the HTML5 platform are grounded compared with the retired Flash technology (still used with the obsolete equipment). The demand for pre-project estimation of hardware and data transmission channels in a target country is proved on the example of Ukraine.","PeriodicalId":391592,"journal":{"name":"2021 IEEE 8th International Conference on Problems of Infocommunications, Science and Technology (PIC S&T)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130896029","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 leads to qualitatively different systems of the G/G/1 type with completely different characteristics. The paper considers various queueing systems (QS) formed by such distributions as: exponential, hyperexponential, Erlang. In contrast to the classical theory, this article considers QS with distribution laws shifted to the right from the zero point. The article provides an overview of the author's results for the average waiting time in a queue in a closed form for systems with input distributions shifted to the right from the zero point. To obtain them, we used the method of spectral decomposition of the solution of the Lindley integral equation. The article presents the spectral decompositions of the solution of the Lindley integral equation for three systems out of sixteen possible and with their help formulas for calculating the average waiting time in the queue are derived. It is shown that in systems with delay, the average waiting time is much shorter than in conventional systems. The proposed approach makes it possible to calculate the average waiting time for these systems in mathematical packages for a wide range of changes in traffic parameters. Considering the fact that packet delay variation (jitter) in the telecommunications standard is defined as the spread of latency around its average value, then jitter can be determined through the variance of latency.","PeriodicalId":391592,"journal":{"name":"2021 IEEE 8th International Conference on Problems of Infocommunications, Science and Technology (PIC S&T)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131403583","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 evaluation based on the representation of interrogation radar systems for observing airspace in the form of two-channel systems for transmitting information of interrogation signals and response signals. It is shown that the use of interrogation signals and response signals in the form of an interval-time and positional code leads to the need for a significant receiving path bandwidth expansion of both the aircraft transponder and the interrogating radar system as a whole. This caused by the requirements for obtaining sharp edges of the received signals, which is necessary for decoding them and leads to a significant decrease in the frequency efficiency of the considered information systems and, as a consequence, to a decrease in the noise immunity of both the request channel and the response channel of the considered information systems.","PeriodicalId":391592,"journal":{"name":"2021 IEEE 8th International Conference on Problems of Infocommunications, Science and Technology (PIC S&T)","volume":"262 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115013218","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}

Data confidentiality ensuring by encryption has faced quantum computing threat, but this problem can be solved by using post-quantum cryptography and / or quantum cryptography (quantum key distribution). For cryptographic applications statistical properties of the generated pseudorandom sequences should not be differ from random sequences. To determine such properties a number of statistical testing methods are used, but they all are focused on the evaluation of binary sequences. In quantum cryptography there are some protocols with Q-trits (qutrits), but these sequences cannot be assessed effectively by binary statistic methods. From this position in the paper quality assessment approach for Q-trits pseudo random number generators and formed sequences was proposed. Also the experimental study of proposed approach (in comparison with NIST STS) was carried out. Given results show that NIST STS technique cannot be used to evaluate the quality of the Q-trit sequences and generators, but developed method is suitable to use in practice for evaluating Q-trit sequences (generators) quality.","PeriodicalId":391592,"journal":{"name":"2021 IEEE 8th International Conference on Problems of Infocommunications, Science and Technology (PIC S&T)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121212774","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}

On the basis of the conducted researches the basic parameters which can be parsed from the required site of online store, namely absence or presence of the corresponding information are defined. An intelligent method for detecting fraudulent online stores has been developed, which allows automating the process of detecting fraudulent sites only by entering a link to the site. The method is implemented on the basis of machine learning classification methods: Logistic Regression (LR), Random Forest (RF), KNN, Naive Bayes (NB), Support Vector (SVM) and DecisionTree (DT). Also, each method of classification is modeled by different approaches, namely: Imbalanced; Undersampling; Oversampling; SMOTE; ADASYN. The realization of method is implemented on the basis of sites operating in Ukraine. There are 67 sites in the dataset, 45% of which are fraudulent.according to the results it turned out that the best simulation estimates are based on the DecisionTree by the approach ADASYN and Random Forest by the approach Oversampling. It shows a 100% result of defining a fraudulent site.","PeriodicalId":391592,"journal":{"name":"2021 IEEE 8th International Conference on Problems of Infocommunications, Science and Technology (PIC S&T)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128297741","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}
