The translator of the visual programming language of Petri-object models is designed and built according to the defi ned formal grammar of the language and Petri-object model formalism. It performs the transformation of the visual representation of the model into the calculation of the simulation algorithm.

Two approaches to the generation of musical works are proposed and considered, namely using the method of notes and the method of chords. The research of both methods was carried out, and their advantages and disadvantages were formulated. As a result it was decided to use the method of notes as the main one for music generation. The process of searching and processing data for learning a music neural network is described in detail, the algorithm for converting data from MIDI format to your own text for use in a neural network is considered in detail. The learning process of the neural network was also described, and the learning speed was compared using GPUs and CPUs, as a result of which it was determined that learning takes place faster using a graphics processor, in some cases 5.5 times. As a result of testing the operation of the neural network, it was determined that the optimal characteristics of the recurrent neural network for music generation is a network consisting of 4 LSTM layers, each with a dimension of 600 neurons. As music generation cannot be assessed by objective characteristics, a special focus group survey was conducted to assess quality. It shows that music generated by a neural network received almost the same marks as music. written by a man. It should be considered as a great result. It was also determined that it was difficult for the survey participants to correctly identify the author of a musical work, since they correctly identified the authors in only 58% of cases. The proposed solution allows to easily generate musical compositions without human intervention.","PeriodicalId":313885,"journal":{"name":"PROBLEMS IN PROGRAMMING","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115622355","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}

Implemented authorization of system users using the open FirebaseAuth standard. Creating a single service for authorization and registration allows to make the system scalable. The system implements the search for goods by code, as well as viewing stocks in the warehouse with automatic price calculation. The main service of the database is a cloud database of the NoSQL class, which allows storing and synchronizing data between several clients, there is an API for data encryption. In addition, the database remains available only in the application to avoid unauthorized access and editing. While development, it was decided to make an automated control system on the Android OS device, because industrial digitalization (precisely because of the mass introduction of smart devices) requires mobility and accelerated processing of stocks at various stages of turnover.

A comparative analysis was conducted (mostly with SDLF, as its implementation is open, and the implementation by private companies is hidden). The advantages of the proposed concept over the existing ones are examined in detail. Recommendations on how to integrate the concept with data schema control applications are given. A service for streaming data using Apache Beam in Java has been developed. A repository architecture for analytics was designed and developed. A data schema management model was developed as well as a data schema management model and a model for secure access to data.

Virtual machines are used both to host application software and to implement container virtualization. Widespread use of virtual machines develops specialized software to determine the impact of model parameters on the quality of the consolidation process, which will prevent experimental research in production to evaluate new cloud data center resource management strategies. In recent years, there were many approaches in literature that offers various sets of software tools and frameworks for modeling data center processes, providing a platform and the necessary building blocks to optimize the process of consolidation of virtual machines. Models and software tools for modeling data center resource management processes are usually not exhaustive and solve a specific problem or management task. The specialized simulation software presented in the paper allows to investigate different control modes of virtual machines dynamic consolidation, provides a wide range of logging and debugging information using text and MS Excel files, such as performance indicators and workload diagrams, and allows to determine the optimal model parameters for various modes of data center operation, minimizing the number of active physical servers and reducing the number of SLA violations.","PeriodicalId":313885,"journal":{"name":"PROBLEMS IN PROGRAMMING","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127382825","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}
