Turbal, Serhii Babych","doi":"10.31891/csit-2022-4-14","DOIUrl":"https://doi.org/10.31891/csit-2022-4-14","url":null,"abstract":"To improve the information technology of drawing up class schedules, there is a need to develop methods that allow significantly reduce the number of combinatorial objects in the process of algorithms for generating schedules matrices. For example, the result of applying the method of permanent decomposition is a collection of combinatorial objects - permutations, combinations, and placements. For the task of drawing up lesson schedules in the part of forming timetable matrices, the method provides a memory-recorded set of all possible systems of various representatives of sets, which are the columns of the timetable matrices (SRPS). Since the algorithm of permanent decomposition gives all possible SRPS, it creates the problem of forming the final schedule based on SRPS or all possible variants of schedules and requires the development of special algorithms. Certain known approaches to solving such a problem are associated with significant computational complexity in the general case. This also applies to the approach based on the order relation of the set of decomposition matrices. \u0000The basis of the information technology proposed in the work is the further modification of the incidence matrices and, accordingly, such a modification of the permanent decomposition method, which allows generating ready versions of the schedule matrices at the output. This is achieved due to the introduction of a special algebra of additive-disjunctive forms and, accordingly, the possibility of generating such forms in the process of permanent decomposition. In fact, in this context, ADF is a formal representation of a ready-made version of an admissible schedule that satisfies some additional requirements.","PeriodicalId":353631,"journal":{"name":"Computer systems and information technologies","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127241680","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}

With the help of technology, the statistical characteristics of various segments of the web space and their cluster structure are studied. Two methods are used to find the optimal number of clusters and cluster centers: the well-known k-core decomposition algorithm and a new method developed by the authors. The new algorithm is based on the distribution of eigenvalues of the stochastic matrix, which describes the process of Markov transitions in the system. The clustering process is carried out using the Power iteration clustering algorithm. \u0000With the help of written software (crawler), information is collected on a given segment of the web space. For the studied area, there are statistical characteristics, namely: node degree, clustering coefficient, node probability distributions by input and output connections. Oriented and unoriented graphs of web pages of the studied zones are constructed. By combining the calculated dependencies for the input and output subnets, we can obtain the statistical characteristics of the undirected graphs of the web pages of the web space zones that we are investigating. \u0000For cluster analysis, the optimal number of clusters and cluster centers can be found in 2 ways: by the well-known k-core decomposition algorithm and by using a new method developed by the author. The new algorithm is based on the distribution of eigenvalues of the stochastic matrix, which describes the process of Markov transitions in the system. Using the Rower iteration clustering algorithm, the cluster structure of various segments of the web space is studied. \u0000The advantage of the developed information technology is that with its help one can work with large sets of data collected on the Internet, study their structure and statistical characteristics, and perform the clustering process.

The devised approach relies on the connection to the local area network (wired or wireless) of the university, making the board accessible to the internal users, and creation of a network tunnel between the remote user and connected parts. These actions are accompanied by assignments of necessary permissions to the users of the system. First, the requirements of each involved actor were considered and as a result of that further understanding of the network communication process, network management and administration, software requirements, etc. was acquired. According to these results, analysis of the capabilities of SBC in terms of its connectivity was performed and, finally, the architecture was realized on the available hardware with regard to the peculiarities of the specific subject. The article establishes all the necessary details on the implementation of the proposed architecture and discusses results of the testing performed as a part of the specific course. During the testing stage, the deployed system based on FriendlyARM Nano Pi allowed us to organize the course on Real-Time Embedded Computer Systems and successfully finish all related activities under circumstances of remote education. It was demonstrated that the proposed organization is reliable as demonstrates conceivable performance even under condition of multiple simultaneous connections to the target board. From the administrative point of view, the solution is highly configurable which is a huge advantage for the lecturer and for the administrator. The devised architecture has a potential in terms of improvement and scalability because it consumes relatively low network capacity and is easy to deploy under any circumstances.","PeriodicalId":353631,"journal":{"name":"Computer systems and information technologies","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125102647","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}

Therefore, when creating projects, there is a need for a well-founded choice of project management methodologies, which will allow to quickly solve problems that arise in the process of their creation and will provide an opportunity to ensure high efficiency of project-oriented activities of companies. \u0000The conducted analysis of the methodologies showed that today there are a sufficient number of them, among which there are rigid and flexible ones. Among the hard methodologies, as Waterfall model, V-model, Incremental model, Spiral model, and Iterative model are known. Among flexible methodologies, the Agile model, as well as Scrum and Kanban are most often used. The following flexible methodologies are also known: Lean, eXtreme Programming (XP), Rational Unified Process (RUP), Dynamic Systems Development Model (DSDM), Rapid Application Development (RAD), and Extreme Programming (XP). \u0000It has been determined that most researchers prove in their studies that agile methodologies are more widespread nowadays and are better adapted to the conditions of rapid changes in projects. The only exceptions are those methodologies that apply to certain industries, such as medical, aviation, and others. Such fields involve the use of only brutal methodologies. \u0000The article examines the modern Agile approach to project management, its difference from the traditional approach of the rigid Waterfall methodology or others; the scope of application of Agile; a short story; the advantages and disadvantages of implementation and its use. \u0000The article provides a comparative analysis of the most popular today's flexible Scrum and Kanban methodologies. The roles that are indicated in projects in Scrum and Kanban are considered. The events performed by the teams are also analyzed in more detail. \u0000The article elaborates a block diagram for a justified choice of Scrum or Kanban methodology. The article is based on research on the international and Ukrainian markets of IT companies. \u0000The direction of future research of the authors is to conduct a more detailed analysis and comparison of rigid and flexible methodologies with the aim of using combined forms of project management.","PeriodicalId":353631,"journal":{"name":"Computer systems and information technologies","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121157066","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 first and probably the most important step of the research is to collect, store and clean data, the whole result depends on the amount and quality of data. In the next step of research, datasets are analyzed. Lastly, complete report and visualizations are provided. In the study, we propose modern technics, mathematical algorithms, and machine learning approaches to analyze big amounts of data from the Twitter social network in order to forecast the 2022 French presidential election results. The determined outcome is compared with sociological polls and the real results of elections. \u0000In the conducted research modern types of media are compared to select the best one for election prediction. Selected Twitter social network as the one with the most appropriate data and availability to download big amounts of useful information. The approach based on the usage of Python programming language, Selenium browser emulation and MongoDB database was used to collect, store and clean data about the main French election candidates – Emmanuel Macron and Marine Le Pen. The research was made from August 2021 until the election itself in April 2022. The determined outcome is compared with sociological polls and the results of elections and showed that analysis of social network data could be a good alternative to traditional sociological polls as it shows the same trends month by month and well predicted the win of Emmanuel Macron in elections. Moreover, the proposed approach has its benefits compared to sociological polls such as always being fresh, and close to real-time information, the price of research is much lower and could be reused for the next parliamentary or presidential elections with a small modification. \u0000The research could be extended and adapted for other countries. Currently, the proposed algorithms and mathematical models showed good results in the French and Ukraine elections. It works well with English, French, Ukrainian and Russian languages. This allows us to claim that it will also work fine with other Latin or Cyrillic alphabets but for Asian or Arabic languages more research would be needed. Twitter is a good choice for European and American countries. In the future, other social networks should be considered for the countries in which it is not so popular.","PeriodicalId":353631,"journal":{"name":"Computer systems and information technologies","volume":"29 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120925731","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}

Optimizing MCU software in terms of energy consumption requires experimental studies of the energy consumption of the execution of instructions, commands and programs. Due to the lack of specialized measuring equipment that has sufficient accuracy (the error must be less than the difference in power consumption of instructions and commands) and immunity to interference, known models do not allow optimizing the software in terms of power consumption and thereby increasing the operating time of autonomously powered systems without recovery battery charge. And this is important for MCU and IoT modules operating in remote locations, dangerous for people, and critical infrastructure systems. However, a direct study of the energy consumption of MCU instructions, commands and programs as part of IoT modules is very time-consuming. RISC microcontrollers have few commands, but many modes of their execution, so it would be necessary to investigate 10-20 thousand options. It is proposed to use the methods of artificial intelligence for the classification of teams and the forecast of energy consumption of those teams that were not studied. \u0000The basis of the concept of a measuring system for the analysis of current consumption of smart devices and IoT modules can be the architecture developed in this paper.

Ontology population is automated in OpenRefine and INCEpTION based on texts and tables semantic annotation. Data extraction is done in Tabula for tabular data resources and FineReader for drawings. The ontological support was developed according to the model of multi-level concretization employing a distinction between data and rules modules. The ontology of resources is based on a tabular knowledge representation model. The usability of the proposed approach is experimentally evaluated on the example of the sections of the «Mariupol Port-Volnovakha» railway in Ukraine, «Plovdiv-Burgas» in Bulgaria and «Coswig-ESig G» in Germany and the corresponding regulations. The ontology can be used for conventional railways (e.g., 160 km/h), as well as further integration with the railway train model can be done. The ontology was evaluated by the domain expert and using the OntOlogy Pitfall Scanner. The scientific novelty of the work lies in the integration of heterogeneous resources of railway infrastructure characteristics by ontological means.
