Sagaing Technological University is located in Sagaing, Myanmar. It was initially established as Technical High School on 17 September 1990. On 1 December 1998, it was upgraded to a Government Technical Institute. It became a Government Technological College on 20 January 2007 and a Technological University on 23 February 2012..
The prospects for using microservice architecture in the development of flexible automated production control systems at mechanical engineering enterprises are considered. Methods for designing and implementing automated production control systems based on microservice architecture are discussed, and the advantages and disadvantages of this approach are shown. A prototype of a flexible automated system, developed using the Java language and the Spring framework, was proposed for the butt welding section of a metal disc production plant. The developed concept is a set of software modules in the form of microservices for independent data processing at each stage of the production process, which increases the fault tolerance and reliability of the entire system.
Using machine vision technology to manage assembly kits in a warehouse allows for automated inventory control and management, improving the accuracy and speed of data processing. The implementation of such systems reduces the influence of the human factor, minimizes errors during inventory, and ensures prompt updating of information in the accounting system. This article discusses methods for recognizing objects using computer vision, including image processing, marker or barcode detection, and the use of neural network algorithms for component classification. The advantages and limitations of different approaches are analyzed. The results of this study demonstrate the effectiveness of using machine vision for automated inventory control of assembly kits, which helps optimize logistics processes and reduce warehousing costs.
The article presents a thermoconvective three-dimensional spherical model of the modern Earth geodynamics constructed by the authors, based on the SMEAN2 global seismic tomography model with plate rheology on the surface. The fundamental result is that the numerical three-dimansional model of flows in the spherical mantle layer produces an image of horizontal movements of lithospheric plates on the Earth’s surface that agrees with the modern kinematic plate tectonics model, as well as with satellite observations of horizontal displacements on the Earth’s surface. This agreement allows us to reasonably assert that the three-dimensional model of modern material flows for a spherical Earth is a generalization of the plate tectonics concept, which has been developed for half a century within the framework of kinematic theory using mainly two-dimensional convective models of mantle flows, which can describe only regional processes. We consider application of the model to explain some features of regional tectonics.
Capillary waves on the sea surface strongly influence scattering of both optical and microwave radiation. Although the amplitude of capillary waves is fractions of a millimeter, the slopes formed on capillary waves often exceed 30°, which leads to a strong change in the effective reflection coefficient, absorption, and backscattering cross section. Capillary waves are studied in detail in pools, but they have not been measured in natural marine conditions. In this paper, a remote method for measuring slopes, amplitude, direction of the wave vector, and structure of capillary waves in natural conditions is proposed. The method is based on recording the distortion of laser beams incident from top to bottom on the sea surface with a video camera. The authors managed to solve the inverse problem of calculating all the parameters of a capillary wave based on the shape of a capillary lattice in video frames. The sensitivity of the method for measuring the wave amplitude is 30 µm at a distance to the surface of over 4 m.
The colloid-chemical properties of water-soluble and poorly soluble poly(ethylene oxide) and poly(propylene oxide) block copolymers (pluronics), as well as the rheological properties of interfacial adsorption layers (IALs) formed by them and the polymer generated during polymerization initiation on the particle surface, were studied. The temperature, surfactant concentration, and polymer effects on the effective elastic modulus, determined during the lateral deformation of IALs, were evaluated. The strongest interfacial layers are formed by the poorly water-soluble pluronic, which contains a hydrophilic polyoxyethylene block surrounded by two hydrophobic polyoxypropylene blocks. The high strength of the interfacial adsorption layer on the particle surface affords polymer suspensions with high (up to 33
