DESIGN OF THE CONTEMPORARY GARMENTS ON THE BASIS OF THE TRANSFORMATION OF STYLISTIC AND ARTISTIC-COMPOSITIONAL CHARACTERISTICS OF TRADITIONAL DECORATIVE ART

The purpose. This research aims to analyze artistic-compositional characteristics of Ukrainian traditional embroidery and decorative-applied art (using the example of M. Prymachenko’s art) used in the decoration of the actual ethno-styled garments. Methodology. A systematic approach was used in this research to project authorial contemporary garments: literary-analytical, morphological, and comparative analysis of the creative primary source, associative means of its adaptation to the actual fashion trends. The methodology of the research is based on the systematic analysis of the design projects using elements of the cultural heritage of Ukraine. Systematic-informational and visual-analytical methods were used in this research. Systematic-structural analysis was used to analyze the transformation of artistic-compositional elements in the process of shaping contemporary costumes based on associative transformations. Results. In the process of design project of the authorial collection of female Ethno-style clothes, it was found that decorative art and national garments have a high level of authentic symbolism if used for the actual projection image in conditions of contemporary design activity. Characterizations were given to some principles of implementation of the national image in contemporary trends of fashion industry development. Symbolic image of the floral ornament adapted from Prymachenko’s works as well as stylization of her works in ornamental motifs of the collection were used. Based on pre-project analysis and customer survey it was defined that there is significant interest in national motifs. A collection of female clothes targeted at a wide group of customers was designed. Scientific novelty. Principles of design-project of the collection of contemporary garments with authorial embroidery were proposed using an adaptation of national traditions of female clothes embroidery and folk-art decoration as a basis. Usage of different floral motifs and geometric ornament in ethno-style and implementation of this image as popular among contemporary women in their everyday life were justified. Practical significance lies in the development of principles of formation of authorial costume collection project-image, in justification of principles of ethnographically oriented prints and embroidery and the choice of decoration methods of contemporary female clothes.

Dynamic Autonomous Identification and Intelligent Lighting of Moving Objects with Discomfort Glare Limitation

The importance of reducing discomfort glare during the dynamic development of high luminance LEDs is growing fast. Smart control systems also offer great opportunities to reduce electricity consumption for lighting purposes. Currently, dynamic “intelligent” lighting systems are a rapidly developing field. These systems, consisting of cameras and lighting units, such as moving heads or multimedia projectors, are powerful tools that provide a lot of opportunities. The aim of this research is to demonstrate the possibilities of using the projection light in dynamic lighting systems that enable the reduction of discomfort glare and the light pollution phenomenon. The proposed system allows darkening or reducing the luminance of some sensitive zones, such as the eyes or the head, in real-time. This paper explores the development of the markerless object tracking system. The precise identification of the position and geometry of objects and the human figure is used for dynamic lighting and mapping with any graphic content. Time measurements for downloading the depth maps, as well as for identifying the human body’s position and pose, have been performed. The analyses of the image transformation times have been carried out in relation to the resolution of the images displayed by the projector. The total computation time related to object detection and image display translates directly into the precision of fitting the projection image to a moving object and has been shown.

English Classroom Immersive Teaching Based on Digital Twin Technology

In order to improve the effect of English classroom teaching, this paper builds an immersive teaching model of English classroom based on digital twin technology. Moreover, in order to reduce the cost of the system, simplify the system structure, and enable learners to observe the stereoscopic display image with the naked eye, this paper builds an immersive hemispherical projection teaching system, designs the overall structure of the system and various components of the hardware, and studies the projection image predistortion algorithm. In addition, this paper uses the immersive experience between virtual reality technology and immersive teaching as a connection point to design an immersive teaching based on VR and apply it to teaching practice to test the effect of immersive teaching, and perfect the immersive teaching design model based on VR. Finally, this paper designs an experiment to verify and analyze the performance of the system. From the experimental results, it can be seen that the English classroom immersive teaching model based on digital twin technology constructed in this paper is effective.

SPIRE, Surface Projection Image Recognition Environment for bicontinuous phases: application for plastid cubic membranes

Bicontinuous membranes in cell organelles epitomise nature’s ability to create complex functional nanostructures. Like their synthetic counterparts, these membranes are characterised by continuous membrane sheets draped onto topologically complex saddle-shaped surfaces with a periodic network-like structure. In cell organelles, their structure sizes around 50–500 nm and fluid nature make Transmission Electron Microscopy (TEM) the analysis method of choice to decipher nanostructural features. Here we present a tool to identify bicontinuous structures from TEM sections by comparison to mathematical “nodal surface” models, including the hexagonal lonsdaleite geometry. Our approach, following pioneering work by Deng and Mieczkowski (1998), creates synthetic TEM images of known bicontinuous geometries for interactive structure identification. We apply the method to the inner membrane network in plant cell chloroplast precursors and achieve a robust identification of the bicontinuous diamond surface as the dominant geometry in several plant species. This represents an important step in understanding their as yet elusive structure-function relationship.

An application of filtered back projection method for computed tomography images

Mathematical methods take an important part in reconstruction technologies of radiographic image. Back projection, iterative, and analytical (Two-dimensional Fourier, Filtered Back Projection) methods are the most important procedures for image reconstruction. Whenever there exists numerous projections, analytical methods have a great performance in speed and accuracy and due to these advantages they are comprehensively used for X-ray imaging. One of the widespread used methods in tomographic image reconstruction is Filtered Back Projection (FBP) algorithm. This paper presents an application of this reconstruction algorithm for a generated image of the object. Shepp-Logan filter is used to form the filtered back projection image and performance improvement is investigated. The obtained images indicate that FBP algorithm can be substantial for various applications in the field of medicine and industry.
