The optical-acoustic effect, which leads to the excitation of acoustic waves upon absorption of a variable light flux, is considered. A model is proposed for calculating the acoustic field generated by a laser study in a liquid when it hits a spherical object in savagery. Spherical objects can serve as special nanomaterials added to the liquid. The results of an experiment on the excitation of an optoacoustic signal in a liquid by means of a laser for laser flow diagnostics are presented. Since the laser beam is characterized by a set of parameters: power, polarization, wavelength, frequency, phase and direction of propagation, then by changing these parameters one can judge the processes occurring in the investigated stream.

This paper offers an improvement for machine vision based tracking algorithm using NARX neural network. This is achieved by predicting the next position of a mobile agent based on previous movement described by time-series functions. The algorithm remains passive and does not interfere with the quadrotr flight path until detection of multiple agent-candidates, when the tracking algorithm is not able to identify or locate the assigned agent. Meanwhile the NARX training set are updated in parallel with each successful tracking cycle. This process is done to eliminate the overfitting problem of BPTT training.

In modern industry, welding plays an important role for jointing materials and arc welding has been the dominant process for many years. In general, in order to produce a high-quality weld, the system should have two main functionalities. First, it should have the capacity of directing the welding torch based on the detection of the joint location and geometry, namely “seam tracking”. Second, the system should be able to adjust the welding parameters, namely “adaptive control of the welding condition". Both functionalities heavily rely on the sensor systems. The analysis of welding technological processes, adaptive control and intelligent  systems proved the  opportunity of utilization artificial neural networks in the procedure of  weld seam tracking and weld head movement control. Welding process engineering and adaptive correction with artificial neural networks  are considered in the paper both with the computer vision system based on video monitoring and laser profilоmetry.  The paper is focused on the development of a proper sensor system to facilitate the arc welding automation and neural network-based control to provide precise seam tracking and high-quality joints.

A stability problem of milling process is under consideration. A novel analytical tool is presented to assess the optimal cutting parameters which provide a chatter free machining. Chatter instability is broadly studied in the literature. However, the problem of simultaneous optimization of radial and axial depths of cut is kept out of scope. To describe the optimization method a single-degree-of-freedom model of milling process is investigated as well as corresponding equation of motion and function of cutting force. A unified delay-differential equation is proposed. A theorem of asymptotic stability is suggested. Suggested optimization technique allows to create a diagram of radial and axial depth-of-cut dependence.  As shown, there exists an extremum of function of axial and radial depth-of-cut dependence.

Одним из важнейших факторов, исключающих возникновение дефектов типа пор, расслоений, участков с неполной полимеризацией связующего в формуемой высоконагруженной полимерной композитной конструкции, является управляемость процесса во всем объеме композита. Для обеспечения однородности процесса полимеризации связующего предложен метод многокритериальной оптимизации процесса на основе математической модели, связывающей процессы распространения тепла и кинетики полимеризации. Система связанных уравнений процесса, учитывающая экзотермическое тепло, выделяемое при полимеризации термореактивного связующего, изменение теплоемкости и теплопроводности композита при фазовых переходах от жидкого к гелеобразному и, далее, к твердому состоянию, точную геометрию технологической системы, включая прессформу, а также интенсивность тепловыделения независимо управляемых нагревателей, реализована в виде конечноэлементной модели. Предложенный метод синтеза закона оптимального управления нагревателями, использующий метод множеств Парето, проиллюстрирован на примере полимеризации разностенной композитной конструкции, формуемой из стеклопластика.
