Анотація: (English) Modern innovative technologies require new materials that combine high thermal conductivity and high electrical conductivity in order to significantly enhance technical performance. A new composite material has been invented and developed, which possesses both high thermal conductivity and high electrical conductivity. The new composite material is capable of absorbing and dissipating significant amounts of energy within very short time intervals. The material is capable of absorbing and transmitting significant amounts of energy over a distance while maintaining maximum mechanical strength. It demonstrates exceptional reliability in preserving precise geometric shapes under the influence of high concentrations of temperature, energy, and other harmful or extreme impacts. Formulation of the new composite material as a product: ● a composite material featuring an advanced three-dimensional (volumetric) structure composed of numerous identical multi-layered spherical shells encasing spherical cores; the cores with shells (capsules) are bonded together through a series of sequential technological processes and possess an equivalent contact structure form between all capsules. ● the composite material possesses properties of ultra-high thermal conductivity and ultra-high electrical conductivity; ● the composite material exhibits high mechanical strength, is resistant to the development of internal mechanical and thermal stresses, and consequently, to the occurrence of internal deformations; ● the composite material is capable of withstanding high pressures and, under the influence of these pressures, can cause at least some of its components to enter a state of cold-flow behavior. This allows for the calibration of the three-dimensional geometric shape of the structure and ensures very precise geometric dimensions of the structure with a high degree of repeatability.

Of particular importance for the progressive and fruitful development of the innovation process in general and especially the innovation process in the USA is the fact that a multidisciplinary specialist who has knowledge and skills in basic exact disciplines and in the Theory of Inventive Problem Solving and the Algorithm for Solving Inventive Problems must also know the specifics of technical standards and restrictions adopted in the USA in order to successfully adapt them for use in the conditions of each specific project. Numerous attempts to find a curriculum that would produce a well-rounded technical specialist have encountered many parallel problems. The Theory of Inventive Problem Solving and the Algorithm for Solving Inventive Problems are the most important complex analytical professional engineering tools for developing projects of any complexity in the innovation process For successful and effective application of the specified tools, it is necessary, in addition to comprehensive and deep engineering knowledge and skills, to have skills and positive experience in creatively adapting the laws and postulates of the theory and algorithm in a real innovation process.

The analysis covers technological and organizational aspects of transportation, logistics strategies, and supply chain management approaches in this field. Particular attention is given to the integration of digital technologies, such as IoT, ERP, and SCM systems, to optimize delivery processes, reduce costs, minimize losses, and enhance construction efficiency. Based on a literature review, the study formulates the hypothesis that implementing an integrated digital platform in the logistics of bulk materials can ensure the sustainability and quality of construction projects. The methodological framework includes a systematic analysis and a comparative literature review, allowing for the identification of a scientific gap. The findings of this study may be of interest to researchers and postgraduate students specializing in transport logistics, innovative construction technologies, and supply chain optimization, as it provides an in-depth analysis of uninterrupted bulk material delivery dynamics in the context of modern infrastructure projects. Additionally, the results may be useful for practicing engineers and experts in government regulatory bodies seeking to implement advanced methods to improve reliability and economic efficiency in large-scale road, overpass, and highway projects.

In conditions of limited access to qualified engineers, remote diagnostics via video communication is becoming a promising solution. This article examines the effectiveness of remote troubleshooting using video chats, analyzes factors affecting the accuracy of diagnostics, and proposes a standardized interaction protocol. The experiments included an assessment of various diagnostic scenarios, an analysis of communication quality requirements and the identification of types of breakdowns that can be eliminated without the physical presence of a specialist. The results showed that about 65% of faults can be correctly diagnosed remotely, provided that the conditions of a stable Internet connection and clear interaction with a technician on site are met. The developed technique allows to reduce equipment downtime and reduce service costs.
