NONEQUILIBRIUM THERMODYNAMICS. FIELD THEORY AND VARIATIONAL PRINCIPLES

Posted in 2020, ENGINEERING, Issue № 03(93) March 2020 | 0 comments

The article offers a general theoretical review of the concepts of nonequilibrium thermodynamics from the basic postulates of the classical field theory and its variational principles. Onsager’s linear thermodynamics and its principle of least energy dissipation are considered in the paper. Particular attention is paid to another formulation of this principle, formulated by I. Gyarmati, in the space of forces with constant flows for a local functional. The authors also focus on the principle of minimum production of Prigogin’s entropy.

PRELIMINARY PROCESSING OF SCENE IMAGES TO DETECT SEARCHED OBJECTS

Posted in 2020, ENGINEERING, Issue № 03(93) March 2020 | 0 comments

The paper formulates the problem of preliminary processing of scene images to detect specific objects – route vehicle number on color images obtained by shooting on mobile devices. Otsu method is considered as the available high-speed preprocessing methods for obtaining the optimal approximation of a grayscale (gray) image, as well as a number of standard local processing methods in a sliding window. The authors propose two heuristic pre-processing methods:

Non-adaptive conversion of color images to gray (sharpness predictor);
Gray image blurring method (ROS method), used to detect the contours on it.
The test images demonstrate the effect of applying various methods to highlight the contours and localize the area where route vehicle number is located in the images. These methods were comparised on other data – color photos and a three-color cartographic images.

SOFTWARE PACKAGE FOR MODELING DYNAMICS OF CYCLIC AUTOMATION MECHANISMS

Posted in 2020, ENGINEERING, Issue № 03(93) March 2020 | 0 comments

Products of modern technology, which include mechanisms and mechanical subsystems of cyclic automation, are complex technical objects. Effective development of such objects under the conditions of fierce competition (tight deadlines, high characteristics required, the need to minimize material costs for design and debugging) is impossible without the use of design automation.

The problem of constructing mathematical models of designed products and their subsystems is central to the implementation of CAD since the success of design results depends primarily on the quality of the models.

The article discusses the software package for modeling the dynamics of cyclic automation mechanisms using the software in the SolidWorks software package and the subsequent analysis of the dynamics of both individual nodes and the entire system in the MatLab software environment.
