    There are numerous methodological approaches for modelling, numerical analysis and/or simulation of the behaviour of individual systems. However, modelling the interdependencies between task-oriented or dedicated systems (the so-called system of systems) and describing their complex behaviour, necessarily through simulation, is still an unsolved issue.

    This paper examines the integration of artificial intelligence (AI) in airport security, with a particular focus on Sofia Airport within Bulgaria’s critical infrastructure framework. It explores the growing significance of AI in enhancing security protocols at airports, which are critical nodes in national and international transportation networks. The case study highlights a collaborative effort between Sofia Airport and VIP Security, where the “VIP Eye” system was demonstrated to airport officials for testing and feedback. VIP Eye, an AI-driven solution, is designed to detect and mitigate security threats with high precision, featuring capabilities such as weapon detection, masked face recognition, and the identification of physical altercations. The collaboration aimed to refine the system based on insights from Sofia Airport’s security expertise, contributing to advancements in security technology. The study also discusses the broader implications of AI adoption for airport security in Bulgaria, considering both technical advancements and the challenges associated with integrating such technologies within the existing security infrastructure.

    The EU integrates new members through the enlargement process once they meet a number of political and economic conditions. The process encourages democratic and economic reforms in countries that want to become EU members and promotes greater stability and prosperity in Europe.
    Enlargement is the process whereby states join the European Union, after they have fulfilled a set of political and economic conditions. Any European state which respects EU democratic values and is committed to promoting them may apply for EU membership. The accession criteria, or Copenhagen criteria (named after the 1993 Copenhagen European Council meeting which defined them), are the essential conditions all candidate countries must satisfy to become an EU member state. These are: political criteria: stability of institutions guaranteeing democracy, the rule of law, human rights and respect for and protection of minorities; economic criteria: a functioning market economy and the capacity to cope with competition and market forces; administrative and institutional capacity to effectively implement the EU acquis (body of common rights) and ability to take on the obligations of EU membership. The EU’s capacity to take in new members, while maintaining the momentum of European integration, is also an important consideration.

    Security of confidential information has always been an important issue. The aim of this work is to present and discuss the main themes at a new level in steganography methods nowadays. This review paper introduces a comprehensive survey related to nowadays embedding techniques. Steganography is often used with cryptography so that the information is doubly protected, but the combination of these techniques ensures that even if the steganographic method is discovered, the encrypted data remains secure and unreadable without the proper decryption key. This dual-layered approach significantly enhances the overall security of the hidden information.

    New technological capabilities are becoming an increasingly important part of our daily lives. If we want to be sustainable and competitive, we as a society must take advantage of them. The huge volume of data cannot be used effectively without the implementation of artificial intelligence algorithms. And to be effective and useful, data must be protected and secure.

    The study of the acoustic properties of a pipeline section was conducted in accordance with standards regulating acoustic emission testing of pressure vessels and related activities. To achieve this objective, an experiment was performed to emit acoustic signals on the surface of the pipeline section. Based on the test results and assessment, corrective measures were prescribed to restore the pipeline to optimal operational condition. A multi-channel acoustic system was utilized to carry out the tests on the pipeline section.

    In constructing the modern sea bottom mines usually seek a compromise between tactical requirements for this type of weapon and requirements for high resistance against possible mine countermeasure-action e.g. make it a cylindrical shape when you need to put an item on the torpedo apparatus submarines, their shell is constructed in the so-called “stealth” technology and is made of non-metallic materials, increasing the quantity of the explosive when the depth of the region is greater, etc. The article proposes an approach that provides a common solution to all these requirements and allows the construction of a highly functional, versatile, high anti-mining resistance sea bottom mine that has no analogue in the naval practice.
