Deploying Binary Neural Networks (BNNs) presents significant challenges, particularly in selecting suitable hardware to achieve desired performance levels and accurately estimating computational costs. To address these issues, a novel metric named "XNOROP" was recently introduced, offering a simplified approach for estimating the computational cost of BNNs and introducing a method for compressing binary filters. This paper leverages " XNOROP" to define and solve two critical tasks in BNNs. The first task, referred to as the "Forward Task", involves estimating the inference rate of a given model M when deployed on a specific target device T. The second task, known as the "Inverse Task", outlines a systematic procedure to identify a set of target devices T capable of achieving a required inference rate M when deploying the model . Additionally, we extend the foundational formula of "XNOROP" and introduce “LXNOROP” which incorporates considerations for memory access time, enhancing its applicability for real-world deployment scenarios.

A single-axis ground wheeled gyrostabilizer (GWG) with gravity-flywheel control of its two-stage platform, which is understood as a carrier of equipment for optical monitoring of defects in the lower part of the outer surface of an aircraft (AC) at its parking lot, is considered. The purpose of the study is to develop a method for forming the GWG motion trajectory, algorithms for controlling this motion and the angular orientation of the GWG platform during monitoring. The design scheme of a two-wheeled GWG, on the platform of which a camera with an optical axis passing through the center of the wheelset axis is installed, is analyzed. The motion trajectory of the GWG wheelset axis center is formed in a horizontal plane parallel to the plane of the underlying surface of the AC parking lot. Based on the use of a modified dynamic model of GWG motion, an algorithm for its trajectory control of moments developed by the motor-wheel engines as a function of the control linear and angular velocities of GWG motion is considered. An algorithm for controlling the angular orientation of the NCG platform relative to the horizon plane is developed using flywheels as sources of control reactive, gyroscopic, and gravitational moments. The results of simulation modeling confirmed the effectiveness of the decisions made.

Primary transducers of pressure sensors included in the air signal system and whose operation is based on the optical method of data conversion, are considered. The key feature of these primary transducers, emphasizing the significance of this study, is the use of an innovative elastic system consisting of an elastic membrane and a manometric box and possessing a given variable stiffness, which allows linearizing the characteristic of the elastic system as a function of the aircraft flight altitude. Mutually counter, acting at different time intervals, movement of the membrane and the manometric box during pressure measurement reduces the effect of the total elastic hysteresis. A technique for mathematical modeling of the system elastic characteristics, which takes into account the mutual movement of the elastic membrane and the membranes that make up the manometric box, is presented. A generalized algorithm for calculating the elastic characteristics of the system is been developed. Using the ANSYS software package, the strength characteristics of the elastic sensitive elements are determined. A comparative analysis of the system elastic properties obtained using an analytical method, finite element modeling, and experiment, are performed.

A method for remote measurement of resistance of resistive sensors with their two-wire connection in monitoring systems is considered. The method allows to reduce significantly the influence of line resistance and is based on processing the results of integration of the transient process of discharge of a storage capacitor shunting the sensor. Results of experimental studies of the influence of the integration time and the resistance value of resistive sensors on the measurement error are presented. Based on the research results, a model for managing the integration time is constructed, which ensures a minimum range of resistance measurement errors. The error in measuring the resistance of resistive sensors is estimated. It is shown that the presented solution is more efficient than the alternative option for processing measurement results. The advantage of the proposed solution is simplification of communications and switches with a measurement error comparable to the error of systems with three- and four-wire sensor connections. The proposed measurement method can be used in multichannel systems for measuring parameters of objects and environments, in particular, temperature.

Two methods of determining navigation parameters using an astronavigation system with a star tracker, which is a digital camera with a wide field of view, are considered. The first method used in marine astronomy is a traditional difference-altitude-azimuth method for solving the navigation problem of observing a group of stars and the visible horizon. The second method, used in, is based on measuring the orientation of a star tracker in an inertial (equatorial) coordinate system and its relationship to geocentric and local geographic coordinate systems. It is noted that the use of a high-resolution digital camera as a star sensor for astroinertial navigation systems makes it possible to implement both methods for determining navigation parameters. It is emphasized that the nature of the errors in determining orientation by the two methods under consideration is different, so that their combined application increases the accuracy of solving the navigation problem. A scheme of an algorithm for the integrated application of orientation data relative to the horizon based on the readings of inertial sensors and a visible horizon sensor is presented. Results of digital simulation.

Alternative glasses adapt to various surfaces and show high efficiency in a wide range of wavelengths. This solution allows reducing the cost of producing thermal imaging systems without losing quality. The studies were conducted in the process of developing our own thermal imaging lens, the economic assessment was carried out on a wide list of manufacturers and suppliers of materials. The result, confirming the relevance of the work, is the transition to a similar lens using chalcogenide glass.

The features of sheet stamping production are discussed. The technology is characterized by the speed and stability of the manufacturing process of parts with high shape repeatability, and therefore it is widely used in mass production. Due to the appearance of a large number of experimental design works, sheet stamping is increasingly used for the manufacture of small series of products. The duration of the technological preparation of production exceeds the duration of the stamping process itself, which necessitates the use of methods to increase production efficiency, reduce time and financial costs, as well as one of the most important indicators of competitive stamping production is its flexibility - the speed of changeover. The use of modern additive technologies is supposed to bring the changeover speed of stamping equipment to a new level. An overview of publications on the assessment of the possibility of using additive technologies in the manufacture of screw tooling is presented, as well as an analysis of the advantages and disadvantages of using tooling.

The issue of designing polymer parts of the laser head body is being considered in order to ensure its compactness and taking into account the capabilities of additive equipment. The manufacture of such a laser head housing from plastic makes it possible to reduce its material consumption compared to a housing made of aluminum alloy, and it is also proposed to further reduce the material consumption of the plastic housing by introducing special samples and stiffeners into its design. Using the CAE module of the CAD/CAM system of SolidWorks, a comparative analysis of the strength and rigidity of the body parts design options has been carried out before and after their modification; the results demonstrate the possibility to replace the material of the body parts from aluminum alloy to plastic and show that reducing the material consumption and changing the design of the body and its parts does not lead to a loss of its strength and the stiffness, and does not affect the laser head operation. Based on the analysis of the design of polymer parts of laser head housings made on a 3D printer, measures to eliminate the identified deficiencies and the requirement to preserve the optical circuit, a design methodology for nuclear heads is developed.
