You should not think about HOW to format. You should only think about WHAT to write. LaTeX will do the layout for you, and it will always be perfect.

Semushin over the last 10 years. Discrete filtering, identification and disturbance detection for adaptive multidimensional systems are discussed. An overview of identification approaches and detection methods is given and then some new methods, called active methods, are developed.

Any adaptive scheme allows for simultaneous state and parameter estimation of the dynamic model examined. The HBDTD belongs to the class of systems whose state process is unobtainable for any practical use. Hence, the Minimum Prediction Error (MPE) identification methods are hardly applicable because the process to be predicted by the MPE methods can be only the output (measured) process and not the inner state. Recently, a novel methodology, termed the Active Principle of Adaptation (APA), has been developed for time-variant system identification. In contrast to the MPE estimation, the APA-based approach considers Exact System Models (ESMs), rather than Approximate System Models (ASMs) and, hence, yields the new Minimum State Prediction Error method. Here, we demonstrate that modern adaptive estimators, such as the Minimum State Prediction Error methods, can identify the HBDTD models and estimate the hidden biomedical signal.

classes is impairing student striving for individual prominence, one-
upmanship, and hopes for originality. Intending to converting these
drawbacks into benefits, a Project-Centred Education Model (PCEM) has
been introduced to deliver Computational Mathematics and Information
Science courses. The model combines a Frontal Competitive Approach
and a Project-Driven Learning (PDL) framework. The PDL framework has
been developed by stating and solving three design problems: (i)
enhance the diversity of project assignments on specific computation
methods algorithmic approaches, (ii) balance similarity and dissimilarity
of the project assignments, and (iii) develop a software assessment tool
suitable for evaluating the technological maturity of students’ project
deliverables and thus reducing instructor’s workload and possible
overlook. The positive experience accumulated over 15 years shows that
implementing the PCEM keeps students motivated to strive for success
in rising to higher levels of their computational and software
engineering skills.

The article characterizes the state of research and practical developments in this area. It is shown that the adaptor of estimation and control systems should provide a coordinated solution of three tasks: (i) early detection of possible model violations relative to the former model; (ii) unbiased and sufficiently fast convergent identification of the current model; and (iii) computationally efficient modification of feedback in the main control loop. The available advances in solving these problems are characterized separately for many publications and some author's developments. Among the latter is an active adaptation principle for the problem of model identification in a class of linear time invariant (LTI) control systems.

Эта же проблема рассматривается <<в динамике>> с точки зрения системного анализа сложных кибернетических систем. Дается краткое описание новой образовательной платформы под названием SCALE: Skills Countertransference Alternative in Learning Extension - Альтернатива контрпереноса навыков в расширении обучения. Эффективность методологии <<Flipped Learning - Перевернутое обучение>> продемонстрирована результатами социологического опроса студентов. Объективное понимание цифровизации образования в России достигается после анализа компонентов типичной системы <<Адаптивного обучения (США)>>. Гуманитарный аспект дискуссии предупреждает об опасности потери эффективности образовательного процесса из-за принижения роли личности преподавателя при чрезмерном акценте на цифровые технологии адаптивного обучения.
The introduction of digital technologies in modern higher education is discussed statically from the standpoint of multicriteria optimization problem in the conditions of conflict of interests of the four parties involved in the educational process. The same problem is treated <<in dynamics>> in terms of system analysis of complex cybernetic systems. A brief description of a new educational platform called SCALE: Skills Countertransference Alternative in Learning Extension is given. The effectiveness of the <<Flipped Learning>> methodology is demonstrated by the results of a sociological survey of students. An objective understanding of the digitalization of education in Russia is achieved after analyzing the components of a typical <<Adaptive Learning (USA)>> system. The humanitarian aspect of this discussion warns of the danger of losing the effectiveness of the educational process due to the downplaying of the role of the teacher's personality with excessive emphasis on digital technologies of adaptive learning.

The article is concerned with a further development of the Active Principle of parametric system identification in the class of linear, time-invariant, completely observable models. As the identification target model, the optimal Kalman filter (OKF) is designated that is present, no more than conceptually, in the system’s discretely observed response to a training excitation of the white noise type. By modifying the physically given structure into the standard observable model in both the observed response and the Adaptive Kalman Filter (AKF), a so-called Generalized Residual (GR) is constructed equaling the mismatch between the adaptive and the optimal filter state estimates plus an AKF-independent noise component. By virtue of this modification, the GR mean square becomes a new model proximity criterion for these filters. Minimizing this criterion via conventional practical optimization methods produces exactly the same result (AKF = OKF) as would be obtained by minimizing the theoretical criterion being, unfortunately, inaccesible to any AKF numerical optimization methods.
The article presents a detailed step-by-step procedure explaining the above solution in terms of a parameterized transfer function. For the sake of clarity and for stimulating real world applications of the approach, the article employs the transfer function model of a twisted-pair line in a typical xDSL system. The implementation challenges of theoretical provisions of the method are discussed. The issue of extending the proposed approach to the problems of identifying linear models for nonlinear systems is outlined in the directions for further research.
Keywords: LTI model, complete observability, Kalman filter, adaptive fil-
ter, indirect performance index, implementation challenges.

In contrast to the Minimum Prediction Error identification methods, the APA based methods allow for consideration the Exact System Models (ESMs), rather than Approximate System Models (ASMs). This results in a development of a new class of Minimum State Prediction Error Methods.
