Authors: Ziubina Ruslana , Teliushchenko Valentyna , Veselska Olga , Petrenko Andrii
Published: November 2024

Despite advancements in encryption technology, the issue of covert data transmission remains relevant. Researchers are actively enhancing established methods of concealing information with software tools that utilize mathematical models and developing new data entry methods. Steganographic techniques can be used with cryptographic methods to enhance the confidentiality of information within a container or as a standalone software tool. This article examines the steganographic integrity of concealing confidential information within audio files. The steganographic technique was selected as the phase coding method, which involves substituting the audio element’s phase with the secret message’s relative phase. An implementation of the chosen method was developed for the experiment. During the experiment, secret data of varying lengths were used to assess the impact of the length of the concealed information on the distortion of the audio file that may be perceptible to the listener. The study also investigated the resilience of the concealed information to noise attacks, allowing for the determination of the threshold of its robustness. The findings provide insight into the reliability of this steganographic method for hiding classified information within media objects.

Published: November 2024

The study aimed to learn about the experiences and opinions of students and academic teachers regarding the use of artificial intelligence in higher education. The question was answered to what extent and in what way do students and academic teachers of APS use AI in their studies and work? A diagnostic survey method was used, and original survey questionnaires were used. The study involved 58 academic teachers and 139 students. A significant number of academic teachers do not use artificial intelligence, and some of them express open disapproval of its use in education. These concerns include the negative impact of AI on the teaching process and the risks associated with verifying knowledge. A small number of lecturers use AI mainly to search for or create teaching materials. They use AI to prepare lesson plans, generate images, or make classes more attractive. In turn, some of them fear that AI may encourage students to abuse technology in the educational process. Most students declare that they do not use AI, and some are afraid of its inaccuracy and the possibility of making mistakes. Of the students who use AI, they mainly use it to search for information, simplify and correct their work, and create new materials. There is a clear discrepancy between the needs and goals of lecturers and students in the context of AI use. Lecturers perceive AI as a tool to support teaching, but with concerns about its ethical and practical application, while students treat AI as a tool to facilitate everyday learning tasks. The results suggest the need to implement training on the ethical use of AI and its full potential for both lecturers and students to prepare them for the upcoming technological changes in education.

A computer scientist’s perspective on approximation of IFS invariant sets and measures with the random iteration algorithm
Authors: Martyn Tomasz
Published: November 2024

We study invariant sets and measures generated by iterated function systems defined on countable discrete spaces that are uniform grids of a finite dimension. The discrete spaces of this type can be considered as models of spaces in which actual numerical computation takes place. In this context, we investigate the possibility of the application of the random iteration algorithm to approximate these discrete IFS invariant sets and measures. The problems concerning a discretization of hyperbolic IFSs are considered as special cases of this more general setting.

Racial Trauma Unfolds: The Spectacle of Witnessing George Floyd`s Murder
Authors: RICHARDS DonnA , Adjei Paul Banahene
Published: November 2024

Abstract
In this article, we chart some of the detrimental emotional impacts of what we consider a human disaster: denying Black people’s humanity. We focus on the highly publicized and violent killing of George Floyd by Minneapolis police officers in 2020: 9 minutes and 29 seconds of state-sanctioned, anti-Black violence that was filmed and circulated globally and has sparked the largest racial justice protest and beyond since the civil rights movements of the 1960s. We consider the impacts of viewing this footage, this spectacle, on Black people, seeing this human disaster playing out in front of their eyes through the lens of anti-Black racism (ABR), which serves as an analytic lens to theorize this trauma within the context of visceral and ubiquitous anti-Black racism. We further contextualize these links between racism and trauma by drawing from our firsthand experience, as well as the stories, worries, and feelings shared with us by Black professionals, families, and members of the community. We focus specifically on that shared by Black youth, which has primarily been the focus of our professional work. We conclude by highlighting strategies of resistance to counteract these impacts, as well as shifts to clinical practice that might better address them and structural shifts towards social justice.
Keywords: Human-made disasters, mental health, trauma, anti-Black racism, resistance, resilience.

Wacana Tirta Selukat di Desa Adat Bayad
Authors: Dwitayasa I Made
Published: November 2024

Water is one of the means of offering. In Bali, until now, the worship of water is still very strong among the people. This is proven by the fact that there are still many holy places such as Tirta Empul, Mengening, and many other temples in Bali that have springs that are sacred to Hindus. However, not just any water can be used as an offering. To differentiate between ordinary water and holy water, several conditions are required, such as: place and purity. Ordinary water is water that is obtained from clean water places but is specifically used for prayer, such as the jun taneg water (ground water in temples/holy places) or specifically made in the temple area (utama mandala). This water is called toya anyar. Meanwhile, holy water, called ndenagn tirta, is water that has gone through a purification process either based on upacara/upakara or through a mantra process, meaning that the water has been asked before Ida Sanghyang Widhi Wasa so that it becomes tirta (holy water). One of the holy waters in Pakarman Bayad Village named Tirta Selukat. This holy water is located on a cliff surrounded by rice fields which is very sacred to the residents of Pakrman Bayad Village, as a means of purification during the Panca Yadnya ceremony

Humans' inability to understand God in metaphysical form often gives rise to the need to use symbolic or representational means in an effort to understand or describe a sublime and unattainable existence, one of which is a vital object as a symbol of God for the Balinese Hindu community is the existence of flowers in Every offering is considered as a condition that increases aesthetic passion or a condition within the spirit of human relationship with God of Flowers in Hindu religious practices in Bali. The research uses qualitative methods with a descriptive approach used to analyze and describe data from literature studies, strengthening understanding about the presence of flowers in rituals. The results of the research are divided into three discussion points (1) The Significance of Flowers in Hindu Religious Rites in Bali (2) Flowers as a Medium of Offerings (3) Spirit and Blessing: The Role of Flowers in Spirituality and the Human Environment, highlighting the importance of flowers in conveying the sincerity of the human heart in religious ceremonies, enrich spirituality, and deepen understanding of God's existence through religious symbols. Based on this, this research attempts to examine in depth the existence of flowers as a means of ritual through depiction or symbolization which allows humans to associate complex and abstract concepts such as God with something more concrete or visible, such as images, symbols, or rituals. This facilitates easier understanding and helps in forming an emotional, spiritual, or even intellectual bond with the concept of God.

Authors: YAKIMOVA O.P. , GORSHKOV V.G.
Published: November 2024

This paper puts forth a novel vector map descriptor, which is employed as a zero watermark for the purpose of safeguarding digital cartographic data from unauthorized reproduction and distribution. The descriptor is based on frequency analysis and comprises two variants: linear and matrix. This study investigates the stability of the proposed descriptor in the presence of various distortions to the vector map, including shifts, the addition of new objects, and the removal of points. In the course of the experimental studies, fragments of digital maps at three different scales (1:200,000, 1:50,000, and 1:100,000) were utilized. The two variants of the descriptor with different parameters were calculated for the aforementioned vector data, which was then subjected to an attack. Following this, the stability of the descriptor values was evaluated. The results of this research demonstrate that both variants of the proposed descriptor can be applied in practice for digital map copyright protection.

Published: November 2024

The paper presents theoretical and experimental studies of the analysis and processing of raster images with a complex structure. Images of nautical charts have been selected as a representative of such images. Taking into account the need for several stages of processing and evaluating quality criteria on each of them, as well as the difficulty of obtaining manually marked data, real images were replaced with plausible models in accordance with the current GOST R 58251-2018 "Paper navigation maps of inland waterways of the Russian Federation” using the diamond-square algorithm for getting pseudoplanetary relief. A generalized technique of processing of such charts for getting information about the seabed depth marks has been developed, consisting of preprocessing stages, multi-label segmentation, localization, two-stage recognition and data grouping. During the experimental studies, all the developed algorithms were investigated to determine the best set of filtering operations, the type of intelligent model and their hyperparameters according to the criteria of recall, accuracy and processing speed. The final accuracy is 89%, recall is 77%, and the time of processing is 4.3 seconds per megapixel. The obtained results indicate the possibility of using the developed technique for other complex structured images.

THE USE OF DISPLACEMENT OF THE CONTRACTION AXIS ALONG A LINEAR SURFACE LIMITING THE BODILY ANGLE OF SERVICE OF ANTHROPOMORPHIC ROBOTS TO OVERCOME DEADLOCKS
Authors: PRITYKIN F.N.
Published: November 2024

An algorithm for synthesizing hand movements of anthropomorphic robots by velocity vector during the installation of objects of manipulation given, in the form of rectangular prisms in a container, is proposed. The algorithm makes it possible to solve deadlock situations in computer simulation of movements. The essence of the method consists in the use of hand movements, at which the axis of the clash carrier moves and forms with some approximation a rule red surface, which specifies the body angle of service. For this purpose, it is proposed to use a database of configurations that specify certain positions of the output link center and of the accumulation carrier axes which coincide with the above-mentioned line surfaces. The results of calculations of intermediate configurations in computer modeling of movement of anthropomorphic robots in an organized environment using the developed algorithm are presented.
CUBIC FERGUSON CURVE ON A PLANE
Authors: KOROTKIY V.A. , USMANOVA E.A. , KHMAROVA L.I.
Published: November 2024

The paper proposes graph analytic algorithms for constructing a flat parameterized cubic curve passing through preset initial and end points R 1, R 2 with unit tangent vectors T1, T2 specified at these points. The tangent vectors and modules of the first vector derivatives w 1, w 2 at points R 1, R 2 are considered as control elements of the constructed curve shape. Incidence and tangency { R 1, R 2, T1, T2} conditions are supplemented by the condition of obtaining a preset curvature at the initial or end point of the curve. The paper solves two problems: 1) constructing the Ferguson curves with fixed curvature at the initial point R 1; 2) constructing the Ferguson curves with fixed curvature at the end point R 2. Such problems arise when forming a geometrically smooth compound curve with a continuous change in slope and curvature. The proposed algorithms are based on the graphical representation of the curvature vector as a vector product of some auxiliary vectors and the graphical determination of the signed areas of parallelograms constructed on these vectors. The presented examples of constructing Ferguson curves are transparent and can be used in the educational process.
OPTIMIZATION OF THE CREATION OF ASSEMBLY MODELS IN THE SARUS FULL LIFE CYCLE SYSTEM
Authors: RYZHOV A.M. , DENISOVA N.A.
Published: November 2024

One of the main tasks of modern design in many technical fields is assembly modeling. An assembly model is a three dimensional model, that combines models of parts, subassemblies and standard assembly component products, as well as information about the relative location and dependencies between component parameters. In modern manufacturing, it is often necessary to work with assemblies containing hundreds, thousands, or even tens of thousands of parts. Modern geometric modeling systems allow you to work with such volumetric assemblies. However, the process of creating an assembly model is quite long-term and time-consuming. The author participates in the versioned functional testing of the newly developed software package "Digital Enterprise Product Full Life Cycle System" ("SARUS"). The purpose of the study is to optimize the 3D assembly process in the CAD software module. When analyzing the experience of working in CAD, it was revealed, that the most effective way to connect elements in an assembly is to interface along planes, axes and points. It has also been revealed, that the possibility of using this method in SARUS is currently absent. Therefore, a proposal has been put forward to improve the functional part of this software to optimize the creation of assembly models.

The paper considers the "Construction of a coordinate system" (CS). As a result of an analytical comparison of the proposed algorithm of functions and the construction algorithm being performed, it was revealed, that all the CS, created in the process of working with the model, are available in the "Navigator" of the model. Each coordinate system can be accessed at any time to perform various modeling tasks. It is concluded, that accurate reference to a specific coordinate system at the initial stage of creating a 3D model, makes further work with the model using the principle of end-to-end design on the SARUS platform more convenient.

This work is devoted to a study aimed at the development and optimization of algorithms for building 3D models using Boolean operations using PM CAD tools of the newly developed program "Digital Enterprise Product Full Life Cycle System" ("SARUS"). Boolean operations (BO) are mathematical operations that are performing on geometric objects in CAD systems in order to create and modify shapes and structures by combining, subtracting, and intersecting. BO is one of the main tools used cyclically in the design process, which in turn imposes certain requirements on the results of BO execution. The result of performing a comparative analysis of construction algorithms using BO (PM CAD, Compass-3D) is the identification of differences, including certain limitations. Therefore, we have singled out the BO functionality as a separate research issue. This seemingly "simple" multiplication-theoretic operation in geometric modeling has shown the ambiguity of its application in the compared CAD systems.

Published: November 2024

The article presents a methodological approach to visualization of external factors influencing the geometric appearance of the designed helicopter. Visualization of various limitations determined by the operating conditions of the helicopter makes it possible to provide the necessary design solutions at the early stages of design and reduce the complexity of the maintenance work performed in isolated cases. This approach is also applicable to the layout of the crew cabin, passenger compartment and equipment compartments. The resulting system of geometric constraints forms additional requirements for the design of the helicopter fuselage, assemblies and systems, including geometric characteristics that require clarification based on the results of calculations and modeling. The unification of the requirements for the designed helicopters makes it possible to form a parametric model of external factors, which will significantly reduce the design time.

Computer modeling technologies dictate the need to involve related digital resources in the process of work. At the stage of product design development, it is important to prepare a color scheme and present it in electronic format. The rules and laws of color combinations applied in the drawing are transformed in the environment of graphic editors. The online color matching and color scheme generation tool ColorScheme allows you to immerse yourself in the digital space of color combinations, try out various combinations when developing a design project, and understand the logic of working with the classic color circle - the reference scheme of designers and artists. In the process of training students under the professional retraining program "Information Technologies in design", this resource is used for color analysis and the development of a coloristic solution for the interior of public transport.

The report is devoted to the issue of joint application of graphical and biomechanical interfaces of a collaborative robot. Based on the results of the review and analysis of the subject field, the need for a comprehensive intellectualization of the multimodal interface in areas related to the recognition of command information, adaptive adjustment of stored control procedures and integration of interface signals into the overall scheme of the technological process is justified. The structure of an information and control system with an intelligent two-modal interface is proposed, which allows to implement interaction with a collaborative robot. The results of experimental studies are described, revealing the features of the implementation of a visual-gestural interface for controlling an autonomous mobile robot when solving the problem of warehouse maintenance. The possibilities to enhance the developed algorithmic software are discussed.

The article describes a developed and tested methodology for conducting an experimental study of human perception of the graphical properties of a website interface. Studying the perception of information can make the interface more effective. The work used a stationary system that records oculomotor activity using eye tracking technology. With the help of an experimental setup, using eye tracking equipment, it is possible to fix the parameters of the viewing pattern. The article describes a method for preparing stimulus material. The methodology is aimed at studying various factors, such as color scheme, composition and menu layout. Two groups of subjects participated in the experiment: those with artistic training and technical students who did not have special artistic training. Methods of mathematical statistics are used to process the experimental results. The data obtained of the experiment revealed a statistically significant influence of the composition factor. For the group of subjects with artistic training, the influence of the color scheme factor was also revealed.

In order to ensure road safety, one of the most accident-prone areas of Nizhny Novgorod is being investigated. The site is characterized by large elevation differences and small turning radii. A three-dimensional model of this section was built and a VR simulator was developed for driver training. The ability to train drivers under different weather conditions and different road surface conditions has been implemented. To determine safe driving modes, a mathematical model was built that allows one to estimate the moment of skidding. Based on the mathematical model, the optimal speed for given meteorological conditions and the state of the roadway is determined. The data from the mathematical model is planned to be transferred to a dynamic display of variable information in order to inform drivers about safe driving modes, and also be used in a car simulator to prepare drivers for driving in difficult road and meteorological conditions.

Reverse engineering is used in a variety of applications. It can be roughly divided into three main areas: prototyping of new parts, modification of existing parts, and development of completely new components based on existing objects and concept. One of the most popular uses of this technology is the restoration of worn or damaged components that cannot be purchased from the original manufacturer or that lack the necessary documentation. This situation often arises when operating imported or old equipment. This paper discusses the process of obtaining geometric information about an object using reverse engineering techniques. Three-dimensional solid models of individual parts of the bathyscaphe, such as the hull, turbines, dome, pilot bowl, hatch, and technical compartment, were created based on laser scanning data. The possibility of automated creation of geometrically parameterised models of the bathyscaphe hull and other elements is being investigated. The obtained results demonstrate the potential of reverse engineering and rapid prototyping in the shipbuilding industry.
