Institute of Applied Mathematics and Communications Technology Held a Seminar on ‘Mathematical modeling of Queuing systems using Markov counting chains and the presence of a small parameter’
Speaker: Galina Tsareva, post-graduate student of the Department of Applied Computer Science and Probability Theory.
The report examined Queuing systems that consist of an infinite number of identical FCFS servers with a buffer that can store a queue of infinite length, with a Poisson incoming flow of requests to the Queuing system at a constant intensity.
A question of great interest was when each request received by a Queuing system randomly selects and queries two arbitrary servers of this system, and then immediately sends it to one of them, where the queue is shorter. It was discussed in detail that the dynamics of changes in the share of servers in the system can be described using an infinite system of differential equations. For this system of differential equations, a singularly perturbed Cauchy problem of Tychon type with a small parameter is posed. It was emphasized that the presence of a small parameter in the system of differential equations allows describing rapidly changing processes in large-scale Queuing systems, which makes it possible to analyze transients in systems of this type.ф
Alena Devyaterikova is the first in our country to study the features of the development of cognitive and visual-motor functions in preschool children who have had oncology. For this research, a researcher at the Laboratory of Neuropsychology of the Research Institute for Brain Development and Higher Achievements of the Peoples’ Friendship University of Russia became a laureate of the Medal of the Russian Academy of Education “Young Scientist for Success in Science”. The award ceremony took place on November 24 at the press center of the Russia Today media group.
RUDN University took part in the exposition of the Moscow NAUKA 0+ Festival at the Expocentre, the largest popular science platform in 2022 in terms of the number of activities. The University was represented by the Faculty of Science, the Agrarian and Techological Institute, the Institute of Ecology, the Institute of Biochemical Technology and Nanotechnology, the Medical Institute, the Higher School of Industrial Policy and Entrepreneurship, and the university admissions team.
October 8, RUDN University students and 800 schoolchildren set off on a journey through the diverse world of university science. 2 halls, 11 classrooms and a co-working zone — the Science Festival was all over the main building. In addition to the traditional interactive exhibition, RUDN researchers held 26 new format events: short half-hour non-stop master classes.
