Подход к твёрдотельному моделированию геометрических объектов в точечном исчислении

The development of computer-aided design systems involves a combination of fundamental and applied research. The conceptual foundation of the mathematical framework for such systems lies in the notion of a complete geometric body—a geometric set of points where the number of active parameters matches the dimensionality of the space, with the geometric body represented as a distinct part of that space. The analytical representation of these point sets is achieved through the mathematical apparatus of point calculus, which can be generalized to multidimensional spaces. The article compares this proposed approach to solid modeling of geometric objects with existing methods. Examples demonstrating the modeling of geometric bodies using the new approach are provided. The advantages of this ap-proach are emphasized, including the compactness of the analytical description, the elimination of transformation ma-trices, the facilitation of parallel computations within the mathematical framework, and more. Additionally, the article explores the capabilities of modeling geometric bodies in point calculus, such as the representation of isotropic and ani-sotropic bodies as solid geometric objects with a functionally controlled linear or nonlinear spatial structure.

Dynamic Envelope Optimization of Articulated Vehicles Based on Multi-Axle Steering Control Strategies

Steer-by-wire technology, critical for autonomous driving, enables full-wheel steering in articulated vehicles, significantly enhancing maneuverability in complex driving environments. This study investigates dynamic envelope optimization for articulated multi-body vehicles by integrating coordinated multi-axle steering control strategies with higher-order Bezier curve designs. Unlike traditional approaches that primarily focus on single-axle steering, this research emphasizes the advantages of multi-axle steering control, which significantly reduces the dynamic envelope and enhances maneuverability. To address the challenges posed by constrained road environments, a comparative analysis of Septimic Bezier curves under various control point configurations was conducted, demonstrating their effectiveness in achieving smoother curvature transitions and steering comfort. The results highlight the pivotal role of reducing curvature peaks and increasing curvature continuity in optimizing vehicle performance. Furthermore, advanced steering control strategies, such as Articulation Angle Reference (AAR) and Dual Ackermann Steering (DAS), were shown to outperform conventional methods by ensuring precise trajectory control and improved stability. This study provides actionable insights for enhancing vehicle handling and safety in complex driving scenarios, offering a framework for future road design and multi-axle steering system development.

Design and Implementation of Device Circuit of Microcontroller-Based Smart Traffic Light Control System

In this paper, the design and implementation of a microcontroller-based smart traffic light control system is presented. The proposed smart traffic light is meant to mitigate or entirely eliminate hassles encountered by road users, mostly at road intersections. The system is sensitive to road density and therefore operates in smart and normal modes, with normal mode as the default; however, it switches to smart whenever the need arises. The approach adopted includes; typical intersection design, circuit diagram design, circuit analysis and overall system development and implementation. The microcontroller, which serves as the overall system brain is programmed using proteus electronic software; and then interfaced with already calibrated ultrasound modules and other components. Afterwards, it is initiated to confirm that research objectives have been met. The design employs a crossbar to prevent drivers from using a lane when not supposed. The traffic light control system, if implemented would significantly minimize traffic frustrations and ugly experiences road users encounter daily on Nigeria roads. However, this work is centred more on circuit operation and design, circuit analysis and overall system development and implementation.

Evolutionary design features of virtual fashion brand collections: a three-year analysis in the Metaverse era

ABSTRACT This study aimed to investigate the evolutionary design features in recent virtual fashion brand collections, analysing 314 design images from leading brands, such as Auroboros, Tribute, Republiqe, The Fabricant, and RTFKT. The analysis classified key design elements–colour, silhouette, texture, and textile patterns – into three phases: embryonic, transitional, and expansion. Findings revealed that the embryonic phase prioritises symbolising brand identities and goals as main design elements. The transitional phase marked a shift toward increased collaboration and experimental designs in response to emerging trends. In the expansion phase, collections shifted away from foundational design elements, displaying mature aesthetics and greater collaboration. These findings identify the evolutionary design features of virtual fashion in the Metaverse era and highlight insights into its consistency with contemporary fashion sensibilities. This research contributes to establishing a crucial knowledge base for research into the development of affective design systems, addressing consumer emotional requirements in virtual fashion design.

Modeling the appearance of food technologies in the Sixth technological order

The article is devoted to some aspects of creating technologies for the future of the Russian agro-industrial complex. The focus is on the dialectical approach to developing complex agro-industrial complex technologies as a synergetic complex of processes for transforming agricultural raw materials into food products. The range of issues discussed includes: the possible appearance of agro-industrial complex technologies in the Sixth Technological Wave from the standpoint of applied philosophy; the dialectical inevitability of increasing complexity of agro-industrial complex technologies; development of automatic design systems and research automation systems; productive labor of a scientist and engineer of the agro-industrial complex in the Fifth, Sixth and Seventh Technological Waves; the condition for a technological breakthrough into the future of the Russian agro-industrial complex; the dialectic of revolutionary and evolutionary approaches to the development of food technologies. During a leap in the development of food technology, both a radical change in its structure and a surge in functional capabilities occur, as a result of which internal contradictions are weakened. Therefore, with the achievement of a new, higher level of technology organization, there are fewer contradictions with clearly expressed inhibiting factors. However, the contradictions do not disappear completely; instead of some, others appear, but, as a rule, less acute, i.e., characteristic of a higher level of organization. Further development of technology occurs in the form of evolutionary changes: improvement of processes and modernization of equipment. To create innovative technologies, it is necessary to: analyze modern technologies of the Russian agro-industrial complex and their technical support from the point of view of the possibility and expediency of creating in the future systemic technological complexes of industrial production and processing of agricultural products into food products; develop promising programs of search, fundamental, applied and experimental design work with state budget financing on end-to-end technologies of the systemic complex for the period up to the second half of the 21st century and beyond; organize the training of scientific and engineering personnel by combining universities of agricultural and food profiles.

Development of stealth design systems for advanced submarine hull forms to reduce underwater radiated noise and target strength

The stealth capability of a submarine is the key performance to be considered in submarine design since it is directly related to survivability and operational capability. In this study, a system that can be applied from the conceptual design stage for the submarine shape, including the hull forms and appendages, has been developed by considering the two key components that determine the stealth capability of underwater vessels: underwater radiated noise (URN) and target strength (TS). First, for submarine stealth design considering URN, a design optimization technique was developed that can reduce the high flow noise caused by the interaction between the propeller and the vortex generated in various parts of the hull and appendages. And for submarine stealth design considering TS, shape design technology that can minimize the reflections of active sonar was developed through an evaluation method with high adaptability to shape modifications. Finally, by developing the optimization design procedures that comprehensively cover URN and TS, the optimal shapes and arrangements of sail and rudders that can maximize stealth performance have been derived.

ANALYSIS OF THE PROBLEM OF CONSTRUCTING AN ELIPSE FROM TWO TANGENTS

This article discusses the problem of constructing an ellipse by two given tangents and the coordinates of the center of the ellipse, which arises in the development of CAD design systems. When analyzing the sufficiency of the completeness of the initial data, a symmetrical display of the given lines relative to the center of the ellipse is performed, which leads to a parallelogram with an ellipse inscribed in it. The subsequent affine transformation maps the parallelogram into a square with an ellipse inscribed in it. The analysis of the obtained results allows us to conclude that the initial data are incomplete and it is necessary to supplement the initial data with the coordinate of the point of contact of the ellipse with one of the straight lines. When constructing an ellipse from the supplemented initial data, using direct and inverse affine transformations, the points through which the ellipse must pass and the equations of tangents at these points are determined. This makes it possible to compose a system of linear equations in which the unknowns are the coefficients of the general equation of the second-order curve. The resulting solution is analyzed according to the classification of second-order curves for belonging to a real ellipse. The proposed method is compared with the well-known projective-graphical method for solving the same problem.
