Abstract: We consider a multi-server vacation queueing system that operates in the modified multiple vacation policy related to the number of busy servers. The condition for the transition to vacation mode at the time of the release of the server is the lack of customers in the queue and the implementation of one of the restrictions

Abstract: The social systems of many countries are under stress due to longevity and low birth rates. Healthcare has evolved from a treatment orientation to a prophylactic stance. Therefore, greater consideration must be given to lifestyle behaviour and life satisfaction. This has been recently further deepened by the COVID-19 pandem

Abstract: The possibilities of using the Kalman filter for cleaning (filtering) signals from gy-roscopes and accelerometers of a strapdown inertial navigation system (SINS) with a rough initial alighnment on a fixed base are considered. For this, algorithms for averaging filters with forward and backward computations (forward and bac

Abstract: Accelerating deep convolutional networks has recently attracted a great deal of attention due to the demand of real-time applications. SegNet is a typical deep convolution network in the field of semantic segmentation, and also is a smaller and more memory, time efficient model. In this paper, we focus on accelerating the S

Abstract: A Rubik’s Snake is a toy that has been around for 40 years. It is a system of serial chain. It traditionally only allows rotations of its pieces in 90 degree increments. In this paper we are not going to restrict ourselves to these limited number of incremental rotations. We prove a theorem about the sum of rotations of a R

Abstract: Man atempts to know and see what is not visible with the naked eye goes back to the far past. By the combination of concave and convex lenses, in the 16th century, Dutchman Janssen made the first ever-increasing instrument. Robert Hooke was first used to illuminate objects using artificial light and gave a first description

Abstract: The physical-chemical model describing the formation of nonmetal inclusions in welded metal of mild and low alloyed steels was developed. Thermomechanical calculations of reactions, which took place in a welding pool and determined the structure of nonmetal inclusions, were fulfilled. On a basis of the simulation the hypoth

Abstract: In this article I will show quantum qubit information transmission is as elusive as Schrodinger ‘s cat. Since there are two types of information transmission; namely Wiener and Shannon, I will start from mutual information to show that quantum qubit information-transmission is virtual as mathematics is, which is not existed
