Recurrent estimation of Hidden Markov Model transition probabilities using aggregate data is considered. The problem reduced to equivalent identification for discrete stochastic dynamical system under constraints. Using a combination the regularized method penalty functions and Lagrange multipliers method, an estimate matrix was obtained from as well recurrent algorithms which used sequence observations providing real-time estimates. efficiency proposed illustrated by numerical examples.

The problem of irregular electricity consumption during 24 hours is considered. In the process production, transmission and electricity, losses occur. It should be noted that all types losses, other than on lines, are in no way related to nature distribution among consumers. This circumstance makes rational total generated actual. Due need store large volumes workplace, storage facilities have been used. As a result, three-index linear programming with intermediate centers obtained. paper...

The problem of random time delay probability distribution estimation in networked control systems is considered. An identification approach proposed based on system model with equivalent disturbance includes parametric uncertainty determined by unknown distribution. Recurrent algorithms for real are developed. Algorithms the delays, described Markov chain an transition matrix, were also obtained.

Atrial fibrillation (AF) is the most common arrhythmia. Currently, it makes up about 1.5-2% of total population (average age 75-85 years), and expected that by 2050 will be 30 million people in North America Europe. This associated with a five-fold risk stroke, triple increase heart failure, increased mortality hospitalization. methods non-linear analysis rate variability, which are successfully used many scientific studies, becoming more common. In practice, for detecting AF, graphical...
