Automated classification of search objects in a multichannel magnetometric system based on neural network algorithms

The paper presents the main results of experimental studies of the possibility of classifying explosive device (EOD) when performing search tasks using ferrosonde magnetometers. The characteristic features of the EOD in ferromagnetic shells have been determined, for which there are differences in the magnetic moments of large objects, for example, bombs or land mines, from small ones. Each EOD has certain geometric shape parameters and, as a rule, lies at a certain typical depth. A method of conducting a search by an operator in the decision support mode provided by automated classification of search objects in a magnetometric system based on neural network algorithms is proposed. The advantage of using a multichannel magnetometric system for the purposes of classification of the EOD according to the parameters of the magnetic moment, geometric shape and depth is shown. Variants of neural network construction are considered and an algorithm for automated classification of search objects by a self-learning neural network in a multichannel magnetometric system is proposed.

Keywords: magnetometry, magnetometer, neural network.

Innovative technologies and equipment for monitoring the geodynamic stability of critical construction objects

The development results of precision digital graviseismometric equipment for automated monitoring of geodynamic stability and safety of responsible construction facilities. It is a multi-channel measuring complex with a network architecture and identical peripheral digital measuring modules. Each of these modules actually combines the capabilities of three-component measurement and registration of ultra-low-frequency lunar-solar variations of the gravitational field, as well as seismic accelerations in the frequency band of the main geodynamic and structural resonances of buildings and structures. The main digital and measuring structural elements of the equipment describes. It also presents aggregation schemes based on this equipment and a local Ethernet network (or Internet network) of a multi-channel geophysical station. The main purpose of such a station is to monitor the seismic stability of building systems of the object-base type. The terms and definitions and representations used in the article correspond to similar classical terms and representations used in metrology, gravimetry and seismometry, as well as in technical cybernetics and in technical physics.

Keywords: digital graviseismometric equipment, building structures, object-base type system, own geodynamic resonances, geodynamic stability, monitoring, software and measurement complex.

The concept of the multichannel system of registration and analysis of acoustic emission signals

Acoustic emission method is used as a means of analysis of materials, constructions, productions control and diagnosis during operating time. It's important advantages over other control methods are that it only reacts upon upcoming really dangerous defects and its ability to scan large areas or the whole of product without scanning it by a transducer. In the article there are the results of program development for Emiss-2 system communication and acoustic emission signals analyzing which is based on the earlier experimental data. The correlation and signal to noise ratio were evaluated by the algorithm based on frequency spectrum.

Keywords: non-destructive testing, acoustic emission, spectral analysis, the energy of the acoustic signal.

Method of measurement of mass, mass center coordinates and inertia moments of modular design special measurement standards during their verification

A measurement method has been developed that allows for the transfer of units of mass, length in the field of measurements of the coordinates of the center of mass and the moment of inertia from the state primary standards of mass and length to a special standard of modular design through indirect measurements. The mathematical model of measurements of mass, coordinates of the center of mass and moments of inertia reproduced by special standards is analyzed, the main sources of measurement errors are identified and investigated. Estimates of the instrumental error of indirect measurements and methodological errors caused by deviations in the shape and location of the reference measures, external influencing factors (conditions of verification and application of standards, the ejecting force of air), design features, the material used and the method of processing the surfaces of standards, rounding during calculations, basing standards on the verifiable measuring instrument are obtained. The developed method of measuring the mass, coordinates of the center of mass and moments of inertia of special standards of modular design during their verification is certified. The results of experimental testing of the proposed method confirmed its adequacy and the possibility of using special standards for verification. Tests were carried out in order to approve the type of two standards of modular design, the methods of their verification were tested and approved by Rosstandart.

Keywords: mass center coordinate, inertia moment, mass, measurement standard, verification, error.

We chose the theme of Albrecht Durer's work because he was a mathematician and an engineer...

The article describes the experience of introducing elements of problem-based learning into the standard course of the academic discipline Metrology, Standardization and Certification (MSS), read at the Bauman Moscow State Technical University by the Department of MT-4. The use of this practice was caused by the need to strengthen the interest and motivation of students to the subject of study, when, due to the self-isolation regime during the pandemic, lectures were held in a remote (remote) format, and also designed to popularize science and scientific activities in the direction related to measurements and metrological support, using humanitarian techniques in teaching technical sciences.

Keywords: distance education, historical metrology, history of metrology, number system, measure, unit of measurement, history of machines and mechanisms, mechanics in museology, interdisciplinary relations, humanization of education, visibility.
