MATHEMATICAL PHYSICS METHODS IN MODEL PROBLEMS OF RECEIVE AND TRANSMISSION BY SLOT BROADBAND ANTENNAS

2025-06-28T19:53:37+03:00

Electromagnetic rigorous formulation boundary problem for a semiinfinite slotted semitransparent cone is considered. Sources of electromagnetic field are radial electric or magnetic dipoles. Slots are periodically cut along the cone generatrices. The solution method combines the Kontorovich-Lebedev integral transformations and a singular integral equation (SIE) method. Analytical and numerical solutions are given. Semitransparent surface influence and a slot effect on basic electromagnetic characteristics are studied.

CIRCULAR ECONOMY AS THE ECONOMIC BASIS OF THE INDUSTRY 5.0 PARADIGM

2026-01-11T20:28:44+03:00

The article explores the role of the circular economy as the economic basis of the Industry 5.0 paradigm and justifies its importance for the implementation of the principles of human-centricity, sustainability and resilience of industrial development. It is shown that the integration of closed material and energy cycles allows to reconcile technological innovations with environmental responsibility and social value of production. The function of digital technologies of Industry 5.0 as tools for managing circular processes throughout the product life cycle is analyzed. The feasibility of considering the circular economy not as an auxiliary environmental practice, but as a systemic economic foundation of a new industrial paradigm is substantiated. The results obtained form the basis for further research in the field of digital transformation of sustainable production.

AN AUTOMATED SYSTEM FOR SORTING SMD COMPONENTS AS A TOOL TO SUPPORT THE CIRCULAR ECONOMY THROUGH THE REUSE OF RADIO COMPONENTS

2026-01-16T01:41:50+03:00

The paper describes an automated system for sorting SMD components. The architecture of the automated system is presented, the structure of the SMD component dosing module and their feeding to the conveyor line for sorting is proposed. A feature of the proposed solution is the use of instruments for measuring the nominal value of the radio component directly in the dosing module before entering the module for moving them to the robotic manipulator.

A functional diagram of the automated system and a sketch of the SMD component dosing module layout are presented. A description of the algorithm for the operation of the automated SMD component sorting system is given. The proposed solution will allow to increase production efficiency by reusing radio components.

The problem solved in this paper corresponds to the goals of sustainable development, namely the goal of sustainable development No. 12 "Responsible consumption and production".
