Документ Laboratory workshop on the course "Computer Architecture"(Національний технічний університет "Харківський політехнічний інститут", 2024) Povoroznyuk, O. A.; Povoroznyuk, A. I.The laboratory workshop includes methodological instructions for 9 two-hour laboratory works, which include work on determining the PC configuration, controlling the timer and sound, the keyboard, drives on magnetic disks, and controlling the video system in text and graphic modes. Each laboratory work contains an individual task, control questions and the item "Peculiarities of programming" in one of the programming languages Turbo-C or Turbo-Pascal, taking into account the depth of knowledge of the students of a specific programming language. Intended for students of all undergraduate majors in Computer Engineering 123, it can also be useful for both beginners and experienced programmers in creating effective software.Документ Computer architecture(Національний технічний університет "Харківський політехнічний інститут", 2024) Povoroznyuk, A. I.; Povoroznyuk, O. A.; Filatova, G. E.Methodological instructions are intended for the implementation and design of a course project in the educational discipline "Computer Architecture". The purpose and tasks of the course project are the use of theoretical knowledge acquired by students during the study of the course to obtain practical skills in the creation of effective software, using the capabilities of controlling computer modules at the level of input/output control ports, as well as independent solution of a specific professional problem in the specified direction Since this course project is carried out by students of NTU "KhPI" bachelor's degree 123 "Computer engineering" in the 3rd semester, and is the first course project in the curriculum, the "Methodical instructions" also contain information on the basic requirements for the design of text documents, and provides a holistic view of the subject matter, the order of execution and scope of work, the content of the constituent parts of the documents of the course project on the educational discipline "Computer Architecture". Intended for full-time and part-time students of speciality 123 "Computer Engineering", it can also be useful for both beginners and experienced programmers in creating effective software.Документ Application of probabilistic-time graphs for evaluating the effectiveness of the electrocardiological study process(Одеський національний політехнічний університет, 2020) Filatova, A. E.; Povoroznyuk, A. I.; Fahs, MohamadThis work is devoted to the development of a structural model of the patient’s electrocardiological study process based on graph theory, probability theory and the method of generating functions. The developed structural model is presented in the form of a probabilistic-time graph, in which nine main states and an uncertainty state (a set of states that do not lead to the goal) are identified, as well as the probabilistic-time characteristics of the arcs of transitions from one graph state to another. The following are identified as the main states characterizing the process to complete an electrocardiological study: the beginning of the study; indications were defined; morphological analysis of biomedical signals with locally concentrated features was performed; pathological changes were identified; comparison with previous electrocardiological studies was performed; dynamics evaluation was completed; evaluation of treatment effectiveness was completed; diagnostic decision was made; recommendations were issued (the end of the electrocardiological study). For the proposed model of the electrocardiological study process by the Mason method, there are obtained analytical expressions for the generating functions of the entire graph, as well as the part of the graph that characterizes the successful completion of the electrocardiological study. Using the indicated generating functions, analytical expressions were obtained to calculate the average transit time of an electrocardiological study and the probability of successful completion of this process. To get all analytic expressions, a program was written in the Matlab language. The developed structural model of an electrocardiological study in the form of a probabilistic-time graph made it possible to identify the main states and determine the criteria for the effectiveness of the process in terms of average time and the probability of a successful study.
