Functional Modeling of the Vector Image Creation Process

The article presents a systematic study of the process of creating vector images using the IDEF0 functional modeling methodology. A formalized representation of the stages of construction and processing of vector graphics is proposed, taking into account the sequence of information transformation from a conceptual sketch to a finalized digital object. The input, output, control, and mechanism variables that determine the efficiency of the system’s functioning are analyzed. The contextual diagram reflects the main objective of the process.

Research and Improvement of Financial Flows Modeling at Enterprise During the Implementation of Foreign Economic Activity

The article considers modern approaches to modeling financial flows of domestic enterprises engaged in foreign economic activity during the economic crisis caused by military actions in Ukraine. In wartime, enterprises face significant difficulties in managing financial flows due to the instability of the economic environment, and, accordingly, to overcome these challenges, it is necessary to develop adaptive strategies that will ensure the stability of financial flows.

Application of Pseudorandom Number Generators in Machine Learning

This paper presents a comprehensive study of methods for detecting and localizing electronic warfare (EW) sources under complex conditions, which include the influence of intensive intentional jamming, multipath signal propagation, time-varying emission parameters, and dynamic movement of the sources. The relevance of the research is driven by the growing role of EW means in modern armed conflicts and the need to ensure timely detection and neutralization of such threats.

Evaluating the efficiency of a parcel locker network: a case study of variable demand and storage duration in Pardubice city

Last-mile delivery is the last element of the supply chain. It plays a key role in urban logistics processes related to the efficient and environmentally friendly transportation of goods within an urban area. The growth of e-commerce, the need to minimize the environmental impact of transportation, and the increasing demand for efficient delivery services require alternatives to traditional home delivery. Numerous studies suggest that the use of parcel locker networks helps optimize transportation and reduce logistics costs.

MODELING OF PROPERTY EVALUATION OF SYSTEM-ORIENTED MEASURING INSTRUMENTS

The main purpose of system-oriented measuring instruments (MI) is to ensure automated collection, processing, analysis and transmission of measurement data as part of complex information and measurement systems. Such MI are used in automated production systems, intelligent measuring systems, in the control of technological processes and in conducting scientific research, etc. The main properties of system-oriented MI are provided by a combination of modern hardware, powerful digital processing algorithms and integration into automated systems.

Synthesis of a Macromodel for a Virtual Signal Simulator of Adaptive Acoustics

This work is dedicated to the development of a macromodel for the virtual signal simulator of adaptive acoustics, Data@Sim, based on the formal analogy method. The structure of modeling electro- acoustic processes in adaptive acoustics tasks and approaches to the unification of research on electrical and acoustic signals are presented. An algorithm for synthesizing virtual signals that accounts for temporal parameters of sound wave propagation and attenuation, as well as noise and interference effects, is proposed.

MODELING AND PROTOTYPING OF AN ACOUSTOFLUIDIC SYSTEM FOR MICROPARTICLE SEPARATION

This article presents the results of numerical modeling and experimental prototyping of an acoustofluidic microchannel structure for the separation of microparticles suspended in a liquid medium. A two-dimensional model was developed to analyze the influence of geometric and physical parameters on the formation of the acoustic field within the microchannel and the efficiency of particle separation.

STUDY OF RELIABILITY AND FAULT TOLERANCE MANAGEMENT IN INFORMATION AND COMMUNICATION NETWORKS: MODELING AND TESTING OF DEFAULT GATEWAY REDUNDANCY PROTOCOLS

The article is devoted to researching reliability and fault tolerance management mechanisms in infocommunication networks, focusing on modeling and testing of gateway redundancy protocols. The work considers the VRRP (Virtual Router Redundancy Protocol) and GLBP (Gateway Load Balancing Protocol) protocols, which ensure continuous network operation in the event of a primary gateway failure. The purpose of the study is to compare these protocols using the virtual environments EVE-NG and Containerlab, as well as to test them on physical and virtual devices.

DISCRETE APPROXIMATION IN THE PROBLEMS OF PLACING VECTOR GRAPHIC OBJECTS ON A PLANE

This article presents a new approach to finding possible placements of vector objects on a plane using discrete approximation. The proposed method significantly reduces the computational complexity of the problem by converting vector images into a discrete form represented by a pixel grid. This enables faster intersection checks between objects through the analysis of occupied grid elements, thus simplifying the process of modeling graphic placement.
