INFORMATION TECHNOLOGY FOR FORMING A PERSONAL MOVEMENT REHABILITATION PLAN AFTER A STROKE

Introduction. Stroke ranks second in the list of major causes of death and is the leading cause of disability in Ukraine. Synthesis of innovative technologies that help to movement restoration after stroke is an urgent scientific and practical task.

The purpose of the article is to synthesize the information technology for forming a personal movement rehabilitation plan after a stroke on the basis of quantitative assessment of movement deficit according to the evidence criteria.

Results. The technology for information support for forming a movement training personal plan to restore movements after a stroke has been developed. This technology is implemented by the specialized software module “MovementRehabStroke 1.0” for information and consulting support to the physician in determining the plan: movements, programs, movements training duration based on electromyostimulation and / or biofeedback.

The structural and functional model of the operator (physician) and software module “MovementRehabStroke 1.0” interaction has been developed. This module consists of a graphical interface and basic information modules: Database, Module “MovementTestStroke 1.1” for quantitative assessment of movement deficit and Module for forming the personal movement training plan. The interface provides the interactive mode of work with information modules for operator.

An algorithm has been developed for the operation of specialized software module “MovementRehabStroke 1.0” in researching on the formation of a personal training plan for patient movements based on indicators of quantitative assessment of movement deficit, which is provided by the information module “MovementTestStroke 1.1” and information received from a personal electronic medical record (EMR) of the patient: indicators of neurological status, concomitant diseases etc.

Conclusions. The obtained results will contribute to the creation of a new class of mobile means of digital medicine — mobile applications installed in the structure of the smartphones for movements assessment after a stroke, forming the personal rehabilitation plan, and assessment of rehabilitation results.

Keywords: information technology, digital medicine, software modules, stroke, movements, diagnostics, rehabilitation, personal plan, structural and functional model, algorithm, electrical stimulation, biofeedback.

HIERARCHICAL SIMULATION. ALGORITHM FOR PREDICTION OF GLYCEMIC PROFILE FOR DIABETES

Introduction. Diabetes mellitus, a common chronic disease, requires lifelong treatment and, like any chronic disease, requires regular monitoring and self-control at home. Revolutionary changes in glycemic control in diabetic therapy have occurred thanks to the development of sensors for continuous glucose monitoring (CGM), which can, almost continuously, measure the concentration of glucose in the subcutaneous tissue. The most common barriers to CGM use are related to high device costs and lack of insurance coverage for their purchase, alleged sensor inaccuracy, anxiety, which is associated with dislike of wearing the device. Thus, sensors are good but expensive, not affordable for everybody and could be uncomfortable. Therefore, the constant search for alternative solutions remains an important challenge.

The purpose of the article is to show the possibility of using hierarchical modeling technology to develop and study glycemic profile prediction algorithm as, to some extent, alternative to continuous monitoring sensors in a context of limited irregular measurements.

Results. The program-algorithmic structure for realization of the concept of hierarchical simulation is developed. The possibility of conducting research on models of varying complexity is shown. An algorithm for insulin-glucose tolerance test was synthesized. A procedure for predicting the daily glycemic profile by analytical formulas has been developed, which provides an opportunity to assess the trend of glycemic dynamics as an addition to the irregular glucose measurements with a glucometer. A simulation study, the result of which is the visualization of glycemic profile in a context of expected food intake schedule and compensating insulin doses obtained by the analytical algorithm, was conducted.

Conclusions. The proposed hierarchical modeling technology, based on the use of mathematical models of varying complexity, allows to conduct a complex of simulation studies to correct glycemia in diabetes at the preclinical and pre-ambulatory stages. During the simulation of forecasting procedure, configuration discrepancies of the glycemic profile obtained from different models were detected, but they are within the margin of error and reproduce the main trend in the dynamics of glycemia during meals and insulin injections. The calculated bolus doses of insulin are almost identical to those used by insulin-dependent patients. The simplicity of calculations using analytical formulas can be a prerequisite for the implementation of the algorithm in a special-purpose portable autonomous devices or in applications for Android OS.

Keywords: hierarchical simulation, glycemic control system, identification algorithms control forecasting, simulation preclinical trials.

COMPLEX FOR MODELING AIRCRAFTS’ DYNAMIC CONFLICT SITUATIONS IN REAL-TIME

Introduction. Aircraft flight simulation has many solved and open tasks. The development of modern aviation is impossible without high-quality modeling tools, and every new proposed development must be thoroughly tested. Real-time aircraft conflict prevention is one of the key tasks in aviation, and therefore requires solutions and tools for modeling and testing.

The purpose of the article is to provide brief information on identifying and resolving aircraft conflict situations methods, to develop a software package for modeling dynamic conflict situations in real-time.

Methods. Software development of complex is based on the statistical and simulation computer modeling, computational geometry and mathematical analysis methods. The theory of automatic control, navigation and intelligent control methods are used to identify and resolve conflict situations.

Results. The developed modeling complex allows evaluating the quantitative indicators of aircraft simulation in the generated space and examination the features of conflict situations resolution. Modeling of movement, interaction and maneuvering of the aircraft is carried out. In conflict resolution, the experimental system was more efficient than the current TCAS II system.

Testing the developed modeling complex, detecting and resolving conflict situations algorithms was performed using typical research scenarios, ranging from simple conflicts between two aircraft to extremely complex, involving a significant number of aircrafts in a single conflict. The main indicators for the optimal resolution of conflicts are the number and length of maneuvers to avoid a conflict situation with different airspace congestion, with different types of conflict situations associated with violations of the separation rules.

Conclusions. The proposed complex can be used to research the interaction of numerous aircrafts in a dynamic environment, the development and testing of conflict situations resolving methods. The modular structure of the complex allows performing simulations of other elements, such as data transmission systems.

CONTROL OF A NONSQUARE MULTIVARIABLE SYSTEM USING PSEUDOINVERSE MODEL-BASED STATIC OUTPUT FEEDBACK

Introduction. The paper deals with nonzero set-point regulating the first-order linear discrete-time multivariable system. The case where the number of outputs exceeds the number of control inputs is considered. It is assumed that arbitrary but bounded unmeasurable disturbances are present. The assumption that the elements of the matricies arising in the system equation are unknown. However, their bounds are assumed to be known a priori. From practical point of view, it is important to design a simple controller similar to reduced-order or static output feedback (SOF) controllers. A difficulty associated with this problem is in establishing the existence of SOF control to be able to cope with a given system. The three different problems concerning the optimality, ultimate boundedness and robustness features are stated and solved.

The purpose of the paper is to answer the question: is there the SOF control based on the pseudoinverse concept to stabilize some first-order multivariable system with nonsquare gain matrix?

Methods. The methods based on the theory of matricies are utilized.

Results. The pseudoinverse model-based control leading to static output feedback is proposed to reject unmeasured disturbances. The optimality and robustness properties of such controller are established. Numerical examples and simulation results are presented to support theoretical study.

Conclusion. The paper shed some light on the existence of the pseudoinverse static output feedback controllers which can either be optimal (in the absence of any uncertainty) or be robust stable against parameter uncertainties dealing with the linear multivariable first-order discrete-time system in a hard case when its gain matrix is nonsquare (in contrast to the known results).

Keywords: discrete time, feedback control methods, pseudoinversion, multivariable control systems, robustness.

CRITICAL PROPERTIES OF MODERN GEOGRAPHIC INFORMATION SYSTEMS FOR TERRITORIAL MANAGEMENT

Introduction. The issue of the “geographic information system” (GIS) definition is important both for the theory and practice of creating modern GIS of large territories. An analysis of modern studies has shown that most of the currently publicly available GIS definitions don’t meet the needs of modern territorial GIS.

The purpose of the article is to prove the claim that for the management of territories in modern conditions should be used not GIS in the “narrow” sense, but GIS of the new generation, in particular GIS in the “broader” (extended) sense, for example Atlas Geoinformation Systems (AGIS), which correspond to a predetermined structure – Conceptual framework of Atlas Systems of Relational Cartography.

Results. The term Atlas Geoinformation System is defined as GIS of large territories of a new generation. The concept of Atlas Geoinformation System (AGIS) is described. An example of AGIS of a certain class is given. We believe that it is important and useful for practitioners to use the results of this article in the creation of GIS of large territories. Theorists will get a better understanding of the field of geoinformatics research of the next generation, which would satisfy the requirements of modern times.

Conclusions. Inductive and/or deductive inferences on the fairness of main critical properties in modern GIS of large territories are given. In the absence of one of the properties, we can say that there is a corresponding critical disadvantage of the GIS project of a large territory. The criticality is that in the absence of an appropriate property, the GIS project is likely to fail.

Keywords: Atlas geoinformation system, territory management, Conceptual framework, Solutions frameworks, critical property.
