Item Implications of University-Business Cooperation for Higher Education in a Time of Cybernetics: Emerging Trends and Dilemmas(Odesa National University of Technology, Ukraine, 2021) Tarasevich, I. G.; Tarasevich, A.ENG: Universities and business collaborate for their own ends that do not necessarily match. While the industry is always profit-driven and practice-oriented with primarily short-term goals in mind, the university focuses on strategic planning, theory development, and long-term goals. University-business collaboration (UBC) has diverse modes or activities among which the most common are: 1) research and development (R&D); 2) mobility of academic staff; 3) student mobility; 4) curriculum development and delivery; 5) lifelong learning. While the focus of UBC is on conducting practice-oriented research, each university and enterprise have their own unique combinations of activities that reflect their goals and needs. All the five collaborative research activities demonstrate different effects with UBC drivers, barriers, and organizational characteristics that are further explored in the article. Similar to automation, higher education is in many ways a stochastic adaptive control system, the behaviour of which depends on parameters with unknown values. The system has to perform in order to collect specific values of these parameters. The values are crucial as, once collected, they can be used to alter the system’s performance. Following this logic, we consider the five modes specified above as key UBC parameters, put in their emerging trends as parameters’ values, and consider emerging dilemmas and implications for higher education. The key challenge nowadays is around the adaptability of higher education. More than ever before, educators around the world grapple with the idea of whether and how adaptive the modern university should be to the business world needs in the context of global automation. This article is our attempt to add to a meaningful debate around this topic.Item Major Lessons Learnt from an Online Teaching of Automation and Control Courses during the Pandemic and the Way ahead: A Critical Interpretative Synthesis(Public Organization "Ukrainian Assembly of Doctors of Sciences in Public Administration", Kyiv, Ukraine, 2023) Таrasevich, Iryna G.; Tarasevich, Alena V.; Foris, Svitlana M.; Kuzmenko, Mykhailo Y.ENG: Covid-19 brought in adapted frameworks, concepts, and tools into the design and delivery of automation courses at technical universities. Although university digitalization has been around for a while, it has been used primarily for the administrative purpose rather than for teaching and learning. A natural, powerful stimulator, the pandemic pushed the universities to explore new avenues in further digitalization of education. The goal of this critical interpretive synthesis is to make a summary of the major lessons learnt from the online teaching of automation courses during the pandemic and their further implementation. It is also aimed at exploring major tensions and barriers that users (teaching faculty, students, and administrative personnel) have been grappling with. The tensions and barriers are presented in this paper from three distinct perspectives – from the perspectives of students, teaching faculty, and university administrators. Whether students thrive or survive, the faculty rethink and upskill their teaching, and the institution is capable of meeting multiple, often competing needs and shifting priorities of the market – warrants further research on the topic. An important question to be addressed in future inquiries is whether the stakeholders that are engaged in the process of developing, teaching, and taking an automation course, are able to reconceptualize their roles and continue to grow professionally.Item A Model to Control the Formation of Multi-Component Charge Portions on a Blast Furnace Conveyor(National Academy of Sciences of Ukraine, Kyiv, Ukraine, 2020) Rybalchenko, Maria O.; Selegej, Andriy M.; Golovko, Vjacheslav I.; Selegej, S. M.; Mirgorodskaya, O. S.ENG: Introduction. Bell-less tops used in the charging area give significantly wider opportunities for regulating and distributing the charge material along the furnace top radius. Moreover, it becomes feasible to develop the methods for gas flow control and these methods shall differ from the conventional ones. One of such methods is introduction of multi-component portions of the charge with a technology based component ratio. Problem Statement. The bell-less top charging device is not designed for that type of portioning when the charge material mixing is accompanied with a simultaneous shift of one component with respect to other one for a certain set value, while charging. These portions can be formed with the use of computer-aided stock-conveying system, while discharging the material from weighing hoppers into the blast furnace conveyor. Purpose. This research aims at the development of the structure, the functioning algorithms and the mathematical model for the system to control the formation of multi-component mixed charge batches in order to increase the blast furnace productivity and to reduce the specific coke consumption. Materials and Methods. In this research, the methods of automatic control theory and artificial intellect for the synthesis of weight neuro-fuzzy controllers within the automatic control system of charge dosage have been used. The developed system designed to control multi-component charge portioning via PC has been tested by means of simulation modelling methods. Results. There has been developed an algorithm for operating the system for controlling the multi-component mixed charge preparation on the conveyor, given the arrangement of the specified components, their ratios in portions, total volumetric productivity of the conveyor, the variable geometry of the unloaded material, in the connection with the on-line information on the mixing process. The feasibility of the system has been verified by its simulation with the use of standard application tools. Conclusions. It has been established that the designed control system allows the formation of mixed portions of any composition defined by an operator at a given maximum output of the conveyor and prevents its overload in terms of mass or volume.
