Modern facial recognition algorithms make it possible to identify system users by their appearance with a high level of accuracy. In such cases, an image of the user’s face is converted to parameters that later are used in a recognition process. On the other hand, the obtained parameters can be used as data for pseudo-random number generators. However, the closeness of the sequence generated by such a generator to a truly random one is questionable. This paper proposes a system which is able to authenticate users by their face, and generate pseudo-random values based on the facial image that will later serve to generate an encryption key. The generator of a random value was tested with the NIST Statistical Test Suite. The subsystem of image recognition was also tested under various conditions of taking the image. The test results of the random value generator show a satisfactory level of randomness, i.e., an average of 0.47 random generation (NIST test), with 95% accuracy of the system as a whole.

AbstractAmong 2D materials, MXenes (especially their most studied member, titanium carbide) present a unique opportunity for application via colloidal processing, as they are electrically conductive and chemically active, whilst still being easily dispersed in water. And since the first systematic study of colloidal MXene rheology was published in 2018 (Rheological Characteristics of 2D Titanium Carbide (MXene) Dispersions: A Guide for Processing MXenes by Akuzum, et al.), numerous works have presented small amounts of rheological data which together contribute to a deeper understanding of the topic. This work reviews the published rheological data on all MXene-containing formulations, including liquid crystals, mixtures and non-aqueous colloids, which have been used in processes such as stamping, patterning, 2D and 3D printing. An empirical model of aqueous titanium carbide viscosity has been developed, and recommendations are made to help researchers more effectively present their data for future rheological analysis.

Abstract Nowadays, the virtual technology is being widely applied in the area of clothing design and try-on. However, the possibilities of these technologies cover only the contemporary marketable clothes, while the insight in the aspect of historical costume is very limited. In this research, we developed the method that allows to reconstruct and do the virtual try-on of historical men’s suit consisting from four different garments—trousers, shirts, vest, and coat. The method includes, on one hand, the analysis of pattern drafting systems, patterns construction, special means of bespoke tailoring that were popular in the history and, on the other hand, the way of its adapting and preparing to contemporary technologies of 2D and 3D design. The exploration was done with men’s suit and the patterns from the nineteenth century. We studied how the tailors took all measurements, the content of size charts including divisional, direct measurements, and its combination. To parameterize the historical patterns of men’s clothes, we created the schedule of special indexes. We developed the method how to identify the means of garment shaping by steam pressing, which are hiding in the patterns, and how to perform ones by darts. The preparation of historical patterns to virtual try-on was done by CAD. As example, the reconstruction of full-dress suite painted on the Prince Albert of Saxe-Coburg and Gotha’ portrait (1840) was done, and high adequacy between the historical prototype and the virtual suit has been proved.

The main aim of the chapter is to describe how cognitive models, developed using the ACT-R cognitive architecture, can be integrated with the Unity game engine in order to support the intelligent control of virtual characters in both 2D and 3D virtual environments. ACT-R is a cognitive architecture that has been widely used to model various aspects of human cognition, such as learning, memory, problem-solving, reasoning and so on. Unity, on the other hand, is a very popular game engine that can be used to develop 2D and 3D environments for both game and non-game purposes. The ability to integrate ACT-R cognitive models with the Unity game engine thus supports the effort to create virtual characters that incorporate at least some of the capabilities and constraints of the human cognitive system.

Abstract Background To explore the mechanism of NRAGE enhancing radioresistance of ESCC in 2D and 3D levels. Methods Stably NRAGE-overexpressed ESCC cells and 3D-printing models for ESCC cells were established. Then, cellular malignancy indexes, such as cell morphology, proliferation, radioresistance, motility, apoptosis, cell cycle, and proteins of the Wnt/β-catenin pathway, were compared between radioresistant and its parental cells in 2D and 3D levels. Additionally, 44 paraffin ESCC specimens with radical radiotherapy were selected to examine NRAGE and β-catenin protein expression and analyze the clinical correlation. Results Experiments in 2D culture showed that Eca109/NRAGE cells’ morphology was more irregular, elongated spindle-shaped and disappeared polarity. It obtained faster growth ability, stronger resistance to irradiation, enhanced motility, reduced apoptosis ratio and cell cycle rearrangement. Moreover, Western blot results showed β-catenin, p-Gsk-3β and CyclinD1 expressions were induced, while p-β-catenin and Gsk-3β expressions decreased in Eca109/NRAGE cells. Experiments in the 3D-printing model showed Eca109/NRAGE cell-laden 3D scaffolds had the advantage on growth and spheroiding according to the brigbtfield observation, scanning electron microscopy and Ki-67 IHC staining, and higher expression at the β-catenin protein. Clinical analysis showed that NRAGE expression was higher in tumor tissues than in control tissues of ESCC patients from the Public DataBase. Compared with radiotherapy effective group, both NRAGE total and nuclear and β-catenin nuclear expressions were significantly upregulated from ESCC specimens in invalid group. Further analysis showed a positive and linear correlation between NRAGE nuclear and β-catenin nuclear expressions. Additionally, results from univariate and multivariate analyses revealed NRAGE nuclear expression could serve as a risk factor for ESCC patients receiving radical radiotherapy. Conclusion ESCC cells with NRAGE nuclear accumulation demonstrated greater radioresistance, which may be related to the activation of the Wnt/β-catenin signaling pathway. It indicated that NRAGE nuclear expression was a potential biomarker for monitoring radiotherapeutic response.

In many technologies, such as process industry or water supply, there is a need to measure fluid flowrates. Orifice plates are the most common instruments for measuring the fluid flowrate through pipelines due to their many advantages. On the other side, their use increases operating costs of industrial plants and pipelines. In this work, three new forms of orifice plates were designed and tested. These new forms and one standard, which served as a reference, were designed by using the SolidWorks software package. The aim of the new designs was energy savings, and consequently reduction of operating costs. Energy savings can be achieved by such a design, which decreases the orifice plate resistance an element of the pipeline. This was achieved by increasing the open part of the orifice plate permitting the fluid flow. CAD models of orifice plates were transferred to STL files that were further used for CFD simulation as well as 3D printing of experimental replicas. According to the proposed algorithm, the new designs were tested by CFD simulation performed in the COMSOL Multiphysics software package, by using a finite-difference method. Equations used were based on the Reynolds form of Navier-Stokes equations (RANS, Reynolds-averaged Navier-Stokes), and the continuity equation for incompressible fluids. Next, as we have proposed in our algorithm of development of new orifice plate designs, experimental orifice plates were made by using 3D printing technology and FDM (Fused Deposition Modeling) procedure and tested at laboratory conditions. The results of laboratory tests were compared with the results of CFD simulation. A considerable amount of energy saving was indicated, which was achieved already by the first of the three new orifice plate forms (V1) as compared to the reference (V0). For the other two proposed forms, the effect of energy savings was considerably lower. By using CFD simulation, data can be obtained based on which a decision can be made whether the new shape of the measuring device should be corrected or is appropriate for further laboratory tests. Based on the presented results it can be concluded that the proposed testing algorithm proved useful in designing new forms of orifice plates.

The article explores the development of art decoration tradition in Kyiv-Pechersk Lavra old-printed Akaphistus-books editions of 17-18th cc. The essential elements of art decoration in these Akaphisthus-books are gravures with iconographic images of prayer addressees, corresponding to certain parts of the akaphistus text. The prayer addressee engravings are located in two positions: before or inside of the akaphistus text part. Frontispiece engravings initiate each part of Akaphistus-book. Iconographic posture of prayer addressee in such gravures directs the reader’s attention to the main topic of preceding text – glorification of God, angels or a saint. The frontispiece engraving in Kyiv-Pechersk Akaphistus of the 17th c. are often accompanied with verbal inscriptions, i. e. citations from the well-known church hymns. Quite often baroque poetic texts, which belong to the genre of Ukrainian baroque descriptive poetry, are placed below the frontispiece engraving. Such verbal inscriptions describe images of the engraving, verbalizing the general features of prayer addressee image. The lack of verbal inscriptions on frontispiece engraving in Akaphistus-books of 18th century is compensated by higher quality of the engraving, due to the usage of xylography technique. The image of prayer addressee is frequently used in the center of headset engraving, which precedes the title of each akaphistus text part. The miniatures inside the text part of akaphistus provide visual enrichment of the prayer process. The tradition of small plot illustrations insertion, corresponding to each of the 12 kondaks and ikoses of akaphistus, was initiated by the first Akaphistus editions of 1625 and 1629. This tradition was quite productive during the 17th – early 18th cc. Since the Akaphistus edition of 1731, the miniatures were substituted by engraved initials. The other peculiarity of this edition, which emerged in the subsequent editions of the 18th c., was the usage of engraved frame on each page. Such elements of the artistic decoration enable simultaneous visual and mental perception of akaphistus, declared in introductions to the first Kyiv-Pechersk Akaphistos editions. This masterpiece contamination of verbal and graphic aids in book artistic decoration presents the distinctive feature of the baroque style that influenced the Ukrainian book culture of the 17-18th centuries.
