Non-anticipative strategies in guarantee optimization problems under functional constraints on disturbances

For a dynamical system controlled under conditions of disturbances, a problem of optimizing the guaranteed result is considered. A feature of the problem is the presence of functional constraints on disturbances, under which, in general, the set of admissible disturbances is not closed with respect to the operation of "gluing up" of two of its elements. This circumstance does not allow to apply directly the methods developed within the differential games theory for studying the problem and, thus, leads to the necessity of modifying them appropriately. The paper provides a new notion of a non-anticipative control strategy. It is proved that the corresponding functional of the optimal guaranteed result satisfies the dynamic programming principle. As a consequence, so-called properties of u- and v-stability of this functional are established, which may allow, in the future, to obtain a constructive solution of the problem in the form of feedback (positional) controls. © 2020 Udmurt State University.

On the Stability of a Solution of a Guarantee Optimization Problem under a Functional Constraint on the Disturbance

The paper deals with a control problem for a dynamical system under disturbances. In addition to geometric constraints on the disturbance, it is supposed that all disturbance realizations belong to some unknown L1-compact set. The control is aimed at minimization of a given quality index. Within the game-theoretical approach, the problem of optimizing the guaranteed result is studied. For solving this problem, we use a control procedure with a guide. The paper is focused on the questions of stability of this control procedure with respect to informational and computational errors. The results are illustrated by numerical simulation. © 201

Dynamic monitoring of HbA1c in Russian regions: data comparison of mobile medical center (Diamodul) and national diabetes register of Russian Federation

BACKGROUND: Glikogemoglobin (HbA1c) is a key clinical marker for evaluating the effectiveness of glucose-lowering therapy for patients with diabetes mellitus (DM) and the quality of diabetic care. AIMS: to conduct dynamic monitoring of the quality of glycemic control in DM patients based on a comprehensive examination in mobile medical center (Diamodul) during repeated visits to the regions in 2019 compared with visits of Based Federal program “Diabetes Mellitus” (2005–2010) and data of the National diabetes register (NDR). MATERIALS AND METHODS: The object of the study: patients with T1DM and T2DM examined in Diamodul in 2019 in Voronezh region (Vr), Krasnodar region (Kr) (n = 600), there were “dynamic” group of re-examined (Vr n = 224; Kr n = 113), “random” group of new patients (Vr n = 72; Kr n = 191); group of adult patients from NDR with indicated HbA1c in 2019 (n = 2410067). RESULTS: According to Diamodul, the HbA1c levels are significantly worse than they were reported to NDR: the proportion of patients achieved HbA1c <7% for T1DM is 13.3% and 11.7%; T2DM – 25.1% and 28.6%, in Kr and Vr, respectively; in NDR: T1DM – 37.4%, T2DM – 52.2%. The average HbA1c values in the Diamodul are higher than in NDR by 0.95% for T1DM, 1.41% for T2DM patients. The proportion of patients with HbA1c≥9% decrease in dynamic of examinations through years in T1: in Vr from 53.1% in 2005 and 55.8% in 2010 to 42.9% in 2019, in Kr from 53.2% in 2006 to 43.8% in 2019; also there were decreases in the average HbA1c values in Vr from 9.3% in 2005 and 9.4% in 2010 to 8.8% in 2019; in Kr from 9.1% in 2006 to 8.7% in 2019. In T2DM patients with the best parameters of DM control in a whole, the positive trends were less pronounced and are assessed as non-deterioration: the proportion of HbA1c≥9 % in Vr: 34.7%–34.7%–36.4%, in Kr 40.1%–28.4%; average values of HbA1c: 8.2%–8.4%–8.5% and 8.6%–8.4%, respectively. CONCLUSIONS: The data of the research clearly indicates the need for 100% inclusion of HbA1c in the examination standards in all DM patients at the primary level at least 1 time per year, in order to monitor the real clinical situation, the effectiveness of glucose-lowering therapy and its timely intensification to prevent development of complications

DEVELOPMENT OF THE SOFTWARE FOR THE ANALYSIS AND CALCULATION OF TELERENTHENOGRAMM BY DOCTORS-ORTHODONTS

In the framework of this study, software was developed for the analysis and calculation of TRG. Software development was carried out jointly with the Ural State Medical University (UGMU), the Department of Children's Dentistry and Orthodontics. The software calculates the TRG by its own methods of UGMU, and also has the opportunity to create its own methods for calculating the TRG. In the software, it is planned to use the technology of machine learning (Neural networks). This will help make the process of calculating the TWG easier, since the points from the methodology will be placed automatically
