Method for reconstructing the distribution of unknown spatio-temporal loads in a structure based on viscoelasticity in the Euler-Bernoulli beam coupling

Алемдар Хасанов — 2025-03-30

In this paper, a novel mathematical model and new approach is proposed for the inverse sourceproblem of recovering the unknown spatial-temporal load F(x,t) in the simply supported non-homogeneousEuler-Bernoulli beam governed by the equation p(x)u_tt + μ(x)u_t + (r(x)u_xx)_xx+k_Lu = F(x,t),(x,t)∈(0,ℓ) ×(0, T),resting on a viscoelastic foundation, is studied. It is assumed that the rotation at the left boundaryθ(t): = u_x(0, t), t∈ (0,T),and also the deflection (t):=u(x, T), x∈ (0, ℓ)at the final time T > 0, are givenas measured outputs. The Tikhonov functional is introduce to reformulate the inverse problem as a minimization problem for the Tikhonov functional. Anexplicit gradient formula for this functional is derived. Based on this formula a conjugate gradient algorithm isdeveloped for the considered inverse problem. This algorithm allows to recover the unknown spatial-temporalload with high accuracy, from noise free as well as from random noisy measured outputs.

An An Examination of Holbein Rugs in Restitution Studies

Omer Zaimoglu — 2025-03-30

One of the most important ancient arts of the Turks is the art of weaving. Under the influence of nomadic life, they created textile items that were easy to carry and helpful when needed by weaving. Examples of carpets that are in the pile weaving group from these weavings are today in museums, private collections, and homes.

Carpets woven using natural raw materials experience wear and tear over time due to external factors. Regular conservation and restoration methods can prevent this wear and tear. In addition to these measures, restitution studies are thought to help complete the missing parts in the weavings and determine the pattern, motif, and color information. With the restitution studies, it is possible to see the damaged carpets in their entirety.

The Holbein carpet samples that are the subject of the research have been included in the paintings of the painter Hans Holbein since the 16th century. In this research, the technical, motif, and compositional features of four Holbein carpet samples registered in the inventory of the Turkish and Islamic Arts Museum were analyzed. The missing, worn parts of the carpets and the whole were drawn digitally and restitution studies were carried out, and the images of the whole carpets were included.

Research of the methodology for the development and implementation of a teaching and methodological complex for graphic training

Ауез Байдабеков — 2024-03-30

Modern changes in the field of education are aimed at improving the quality of training engineering personnel. One of the key components of this process is the improvement of the methodological support of the educational process. The article discusses the importance of developing educational and methodological complexes (EMC) and their role in training students of technical universities, as well as the introduction of modern technologies into educational practice. Particular attention is paid to EMCs in engineering graphics disciplines such as "Descriptive Geometry" and "Engineering Graphics and Computer Design". The creation and use of EMCs helps to improve the quality of education, improve students' perception of complex theoretical materials, develop their spatial imagination, mathematical and computational skills. The article provides an example of a successful EMC developed at the Department of Engineering Graphics and Information Technology of the Tashkent Institute for Design, Construction and Operation of Highways, as well as the use of animation technologies to improve the perception of educational material. The presented results confirm the importance of introducing EMCs into the educational process to improve the effectiveness of education. The issue of improving educational and methodological complexes in disciplines is relevant from the point of view of the quality of mastering educational programs by future specialists and, as a consequence, achieving effective results in the training of highly qualified personnel. The article examines the problem of improving and developing a methodology for creating and using educational and methodological complexes that play a key role in the process of graphic training of engineering personnel.

Theoretical Foundations for Improving the Teaching of Engineering Graphics Disciplines Based on the Systematic Approach

Maral Yessekeshova — 2025-03-30

Modern engineering education requires the development of students’ spatial thinking, design skills, and ability to work with digital technologies. However, traditional teaching methods for engineering graphics disciplines do not always ensure a high level of material comprehension. This article examines the advantages of a systematic approach to teaching and its impact on the effectiveness of mastering engineering graphics subjects. The study includes a comparative analysis of traditional, interactive, and systematic teaching methodologies, as well as a pedagogical experiment to evaluate their effectiveness. The results indicate that the systematic approach not only facilitates a strong grasp of theoretical material but also contributes to the development of practical skills necessary for engineering practice. Based on the analysis, recommendations for implementing the systematic approach in the educational process are proposed. This methodology enhances the quality of student training, improves their professional competencies, and adapts the learning process to the modern requirements of engineering education. Additionally, the integration of traditional and digital teaching methods, the use of computer-aided design (CAD) systems, and interdisciplinary interaction are considered. Special attention is given to assessing student engagement in the learning process, as well as the impact of active learning methods on motivation and academic performance. The application of a systematic approach ensures comprehensive mastery of the subject, enhances students’ analytical skills, and facilitates their professional adaptation.

The article examines emotional design as a tool for preserving sacred symbols of Kazakh culture under globalization. The theoretical and practical aspects of integrating traditional symbolism into contemporary design are analyzed. The paper presents empirical research, including interviews with designers and a consumer survey. The role of emotional design in shaping national identity and promoting cultural heritage is demonstrated. Practical recommendations for adapting sacred symbols to modern visual formats without losing their cultural significance are provided.

Keywords: emotional design, sacred symbols, Kazakh culture, national identity, globalization, ornaments, visual communication.

The Concept of Surface Layer in Technical Aesthetics and its Properties

Baimakhan Nurmakhanov — 2025-03-30

The article discusses the concept of the surface layer in technical aesthetics and its role in the structure of finishing and facing materials. Functional, aesthetic and symbolic properties of the surface are determined on the basis of its categories. The surface layers of materials determine their structural characteristics and visual impact, which plays an important role in design and architecture. The article discusses the geometric classification of surfaces, their relationship with shape and the meaning of surface texture. A close relationship is established between the functional and aesthetic properties of the

surface, which take into account not only the technical characteristics of the material, but also the psycho physiological perception of a person. The article discusses the technology of using finishing and facing materials in various industries, which is associated with the technical design of materials, which have recently reached a new qualitative level. The introduction and development of surface design technologies in the construction industry opens up wide opportunities for the implementation of individual design projects. In recent years, a new market has emerged in the production of finishing and facing materials, new developments in surface finishing systems have emerged, differing in texture, texture and color. This study provides a deeper understanding of the conceptual meaning of the surface layer in technical aesthetics.
