Annotation: The traditional response is almost always too late. The very nature of the crisis is changing. It’s faster now. More unpredictable. And our old tools simply can't keep up. When disaster hits, time is everything. And we lose it. Every single time. We lose it while rescue teams are stuck, fighting through ruined roads. And every minute wasted is a life. And here’s the paradox, the author argues. The very tech we associate with destruction — drones — is becoming our single most powerful tool for rescue. This article lays out a new playbook. It’s not just about tech, it’s a new way of thinking. A playbook where drones get there first. First eyes on the disaster. First hands delivering life-saving aid. The first signal reconnecting a world gone dark. The author's methodology isn't just about 'launching a drone.' No. It's about a complete, integrated architecture. This isn't about replacing people. It’s about empowering them. It ties together scouting, logistics, documentation... and—this is key—the ethical rules of the game. This isn't a theory. This system was born from real-world experience, where it's already proven its worth. So, how does it work? It's not magic, it's a clear structure. The author breaks it down into four key parts. Drones for initial assessment. Drones for evacuation and delivery. Drones as a tool for objective documentation. And finally, strict ethical standards to keep it all in check. Bottom line? This model isn't just a tech showcase. It's a shot at rewriting the first few, critical hours after a disaster hits. Turning to waiting and uncertainty... into active, smart, life-saving action. It's about giving people a chance. A chance they never had before.

Annotation: In today's energy system, where renewable energy is actively developing, Energy Storage Systems (ESS) are becoming particularly important. A promising direction for ensuring the reliable and uninterrupted operation of energy systems in the United States (US) is modern approaches to the integration of solar energy generation systems (PV generation) and pumped storage power plants. The study analyzed the technical characteristics of a strategic integration model, its advantages, and potential limitations using the example of Southern Nevada. The article presents key concepts of the economic rationale for integrating PV generation and pumped storage power plants for US energy security. It is argued that the combination of pumped storage and PV generation can effectively smooth out fluctuations in renewable energy generation and cover peak loads, increasing the flexibility and resilience of the power system.

Annotation: The article addresses the challenge of automating architectural quality control in microservice systems designed using Domain-Driven Design methodology. A comparative analysis of the effectiveness of deterministic methods and probabilistic methods was conducted. Using a simulated e-commerce system with a controlled set of defects, a quantitative assessment of Precision and Recall metrics was performed for both approaches. The experiment confirmed that deterministic methods ensure absolute precision in detecting structural boundary violations but exhibit "semantic blindness" regarding complex DDD patterns. Conversely, probabilistic methods demonstrated high effectiveness in identifying semantic defects, such as anemic domain models and context leakage, with an acceptable level of false positives. Based on the results, the necessity of implementing a hybrid verification strategy is substantiated, where static analysis acts as a rigid gatekeeper in CI/CD pipelines, while AI tools serve as an intelligent architect's assistant.

. Designing microgrids with renewable energy sources and energy storage systems//Science online: International Scientific e-zine - 2024. - №6. - https://nauka-online.com/en/publications/technical-sciences/2024/6/06-30/

Annotation: The article discusses the design of microgrids that use renewable energy sources and energy storage systems as a controlled local power system that operates in both grid-connected and island mode. The goal is to present an integrated approach that combines the choice of architectural design (AC/DC/hybrid), the selection of distributed energy resources (DER) and energy storage systems (ESS), and management requirements (power quality control, energy management system) within the framework of the IEEE 1547 and 2030 standards. Key methods for modeling and optimization, such as multicriteria and stochastic optimization, are described, as well as the main challenges to implementation, such as variability in generation, cyber resilience, and costs. Examples of successful projects demonstrate improvements in reliability, flexibility, and economic efficiency for local power systems.
