Nowadays, new approaches have been proposed to overcome the imminent Moore's law failure. The approaches are based on nonlinear or chaos computing and try to reduce the number of transistors to get more computing power. Nonlinear dynamics is an essential source of various patterns that can represent natural systems or perform computational tasks. This work presents a simple hardware architecture to generate different logic gates changing an input voltage. The proposed reconfigurable logic gate is based on the plane equation. This is achieved using two variables of the plane equation as inputs and the other as output. Experimental results are shown to verify the behavior of the proposed voltage reconfigurable logic gate. © 2023 IEEE.

Abstract: We have studied adaptive changes in the circulatory and respiratory systems under the influence of winter soccer training. We examined 50 men, aged 21–25 years (3rd–4th year students): control group—25 people specializing in “soccer” (S), main group—25 people specializing in “winter soccer” (WS). The examination was performed twice, before and after physical activity. Running (average pace, 180 steps/min) for 15 min was used as moderate physical activity. The loads were performed either indoors at a temperature of plus 22–24°C, or in winter outside at a temperature of minus 18–20°C. Indoor and outdoor surveys were carried out on different days. Assessment of peripheral blood flow in the lower extremities was performed using rheography;to assess the main blood flow in the femoral artery, Doppler ultrasound was used. The study of external respiration functions was carried out using pneumotachography. The lactate concentration in capillary blood was determined photometrically. It has been shown that physical activity performed in the cold in adapted athletes (WS group) promotes increased integration between the respiratory and circulatory systems, ensuring the formation of a functional system characterized by stronger connections for optimal adaptation to the combined effects of physical activity and cold. In athletes training indoors (S group) under conditions of physical activity combined with cold, on the contrary, desynchronization of the interaction of the respiratory and circulatory systems occurs, which leads to a decrease in adaptive reserves. Thus, sports training in winter soccer triggers phenotypic adaptive changes and creates a number of physiological mechanisms that promote increased integration between the respiratory and circulatory systems, providing optimal adaptation to the combined effects of physical activity and cold. The obtained facts will be useful for the development of special training programs aimed at increasing the functional rese

The article proposes two algorithmic methods for stabilizing the constant component of the output signal of the measuring circuit with single-coil sensitive elements which are used in sensors for monitoring the metal wear particles in the power plants' lubrication systems. The first algorithm is based on the statistical processing of digital codes obtained as a result of analog-to-digital conversion of voltages at the output of the measuring circuit. The second algorithm involves the implementation of the simplest digital FIR filter "moving average". The efficiency of the algorithms is investigated, and the limits of their applicability are defined. The choice of the "moving average"algorithm as an optimal according to the criteria of accuracy and performance for the correction of the constant component of the signal on the MC outputs in the system for debris monitoring is substantiated. © 2022 IEEE.

In this prezented work paper, on a rectangular , a contact-boundary problem is justificated in a nonclassical interpretation for the Boussinesq-Love equation. Such a kontakt-boundary problem in a nonclassical interpretation has a number of advantages: in this formulation, no additional conditions of agreement are required;this problem can be regarded as a boundary problem formulated by traces in the Lebeg space. It is proved that such a nonclassical contact-boundary problem is everywhere correctly solvable. The work establishes a representation of the solution of the memory problem. In addition, we note that the Boussinesq-Love equation is one of the main model differential equations of mathematical biology. © 2023 IEEE.

The problem of high-precision attitude tracking is studied in this paper under model uncertainty and external disturbance risk. First of all, the kinematics and dynamics model of rigid body is derived based on the quaternion theory. Then, a standard logarithmic sliding-mode function is constructed using the attitude quaternion and its derivatives of the rigid spacecraft, and the corresponding logarithmic sliding-mode controller is also derived. Finally, the stability of the controlled closed-loop system is demonstrated. Consistenting with theoretical proof, the numerical simulation results showed that the controlled rigid body can quickly track its desired attitude command, even if there are model uncertainty and external disturbance risks. © 2023 IEEE.

The paper considers the problem of building a semantic model of the object under study, which determines its attributes, *** composition of the properties inherent in the object. The set of these attributes is a subset of all measured (in a broad sense) properties of the object under study. Processing the results of such multidimensional measurements, observations, registration of expert opinions, etc. gives the initial empirical material in the form of generally logically many-valued assessments of judgments truth of the form 'the property x is inherent in the object g'. On the other hand, the subject may have a priori knowledge about the coexistence variants of various attributes in the object under study. For such circumstances, a method is proposed for identifying all admissible sets of object attributes, including a logical-combinatorial method for choosing the 'best' of these sets, which is taken as a semantic model of the object. The paper considers examples of applications of the developed models and methods, indicates the tasks of additional research of the problem to substantiate the proposed methodology for the semantic identification of an object based on empirical data. © 2022 IEEE.

Identification of the type of combustion-supporting agents (CSAs) by an electronic nose (e-nose) is severely limited due to the absence of untested gas concentration in the e-nose training set. In order to solve this problem, this study designs an e-nose for classifying four CSAs (Diesel, Gasoline, Ethanol and Thinner), and builds cross-concentrations data set. This study uses Gramian Angular Field method that converts one-dimensional time series data to two-dimensional data, and proposes an algorithm named the Multi-Branch Feature Fusion Network (M-BFFNet). This algorithm passes the one-dimensional and two-dimensional data through two different networks and obtains two types of features. First, the algorithm can strength the one-dimensional raw data, integrate the advantages of different networks, and fuse the characteristics of different networks. Second, it can learn the characteristics of volatile gas with specific concentrations to identify the unknown concentrations. Last, a feature fusion module is designed to improve the algorithm ability of learning odor fingerprint. In order to verify the superiority of the algorithm, this study tests the recognition performance of the e-nose based systems and compares the proposed M-BFFNet with traditional algorithms. The results show that the proposed M-BFFNet improves the identification accuracy compared to other algorithms. According to the analysis of this work, the M-BFFNet can be used to identify CSAs with unknown concentrations. © 2023 Technical Committee on control Theory, Chinese Association of Automation.

A policy gradient algorithm integrating long and short-term rewards for soft continuum arm control

The soft continuum arm has extensive application in industrial production and human life due to its superior safety and flexibility. Reinforcement learning is a powerful technique for solving soft arm continuous control problems, which can learn an effective control policy with an unknown system model. However, it is often affected by the high sample complexity and requires huge amounts of data to train, which limits its effectiveness in soft arm control. An improved policy gradient method, policy gradient integrating long and short-term rewards denoted as PGLS, is proposed in this paper to overcome this issue. The shortterm rewards provide more dynamic-aware exploration directions for policy learning and improve the exploration efficiency of the algorithm. PGLS can be integrated into current policy gradient algorithms, such as deep deterministic policy gradient(DDPG). The overall control framework is realized and demonstrated in a dynamics simulation environment. Simulation results show that this approach can effectively control the soft arm to reach and track the targets. Compared with DDPG and other model-free reinforcement learning algorithms, the proposed PGLS algorithm has a great improvement in convergence speed and performance. In addition, a fluid-driven soft manipulator is designed and fabricated in this paper, which can verify the proposed PGLS algorithm in real experiments in the future.
