Marine oil spills pose a severe and persistent threat to ecosystems and coastal economies. Traditional manual or satellite detection is slow, laborious, and error-prone due to sensor limitations, noise, weather interference, small target sizes, and imbalanced datasets. To address these challenges, this paper proposes a novel, integrated framework for the rapid detection and monitoring of oil spills by using the Internet of Things, unmanned vehicles, and transfer learning. The proposed system uses a multi-layered architecture: a physical layer of visual, infrared, and acoustic sensors deployed on a network of Saildrone unmanned surface vehicles for real-time data acquisition; an edge layer for initial processing and low-latency response; and a cloud layer that uses deep transfer learning for accurate spill identification and classification. We fine-tuned pre-trained ResNet models using a Synthetic Aperture Radar oil spill dataset, achieving a peak accuracy of 97.89% with a three-layer transfer learning configuration, outperforming other tested configurations. The efficiency of the system in real-time data handling and leak localization was validated through a controlled experimental prototype. The results demonstrated a robust solution for minimizing response time and environmental impact. Our framework has been proven to gain about 98.3% model accuracy on drone images for oil spill detection.

In the process of train operation, the status information directly reflects the degree of safety of the operation. Online health monitoring and completion of train status assessment are important signs of train intelligent control. To obtain the stress field distribution of the support position (bearing area) of the train, proposed a EMU health monitoring and intelligent state assessment system based on fiber sensing internet of things (FS-IoT). The system adopts the method of combining multiple sensitized FBG sensors into a sensing network to obtain the stress field distribution at the measured location. When the train is faulty or the external environment affects the train’s operation, the stress field and vibration field on the train’s motion components will change significantly. Obtain real-time physical field information of sensitive locations through the FBG sensor array, which can realize online monitoring of train status. A distributed combinatorial optimization algorithm based on FS-IoT was designed, and the weight distribution of FBG test data at different locations on the inversion results was analyzed based on data mining. In the sensitization FBG testing experiment, under the same stress conditions, the sensitivity increased from 12.440 to49.935 pm/kN, and had good linearity. In dynamic testing, when the test carriage passes through the rail connection, there will be significant fluctuations in the center wavelength of the FBG, with a maximum wavelength offset of 2530.2 pm. The peak-to-peak values of the two test data are basically the same, indicating that stress changes can be inverted by the peak position. Finally, a trainstate inversion model based on FBG sensing network and a system framework for intelligent state evaluation are presented, providing new design ideas for train state monitoring.

EN
The article analyzes the role of artificial intelligence (AI) in the renewable energy sources (RES) sector, highlighting its importance in optimizing energy production, distribution, and storage processes. AI enables precise forecasting of energy production, minimizing the effects of weather instability and increasing the operational efficiency of renewable energy systems by up to 25%. AI-based tools also allow for dynamic adjustment of wind turbines and photovoltaic panels, which reduces energy losses and operating costs. An important application of AI is predictive maintenance, which reduces failures through early detection of faults. Smart grid management enables the optimal use of renewable energy sources by analyzing demand and supply and integrating different energy storage technologies. AI also supports the planning of renewable energy investments, helping to select optimal locations for wind and solar farms. However, the implementation of AI in the energy sector faces challenges, such as the need for access to large data sets, the cost of integration with existing systems, and cybersecurity issues. Despite these barriers, the future of AI in RES looks promising, especially in the context of its integration with IoT, big data and quantum technologies. With the right technological and regulatory support, AI can become a key element of the global energy transition, increasing the stability and profitability of renewables and supporting the fight against climate change.

Students attending the lecture on quantum information technology are mostly at the level of completing their master’s theses in the disciplines of AEEiTK or ITT. The task is to write a short essay by each student on the hypothetical addition of a narrowly applicable QIT layer to the actual implementation of the thesis, if possible. In most cases, this is possible because QITs cover a very wide range of potential technical applications. Where this is not possible, or in the case of an undefined thesis topic, students should write a more general essay or write their personal opinion on what they think about the future of QIT. The current article is another part of a series of works on this topic with subsequent student groups.

Content available Influence of IQT on research in ICT. Part 4
EN
The advanced Quantum Information Technologies subject for Ph.D. students in Electronics Engineering and ICT consists of three parts. A few review lectures concentrate on topics which may be of interest for the students due to their fields of research done individually in their theses. The lectures indicate the diversity of the QIT field, resting on physics and applied mathematics, but possessing wide application range in quantum computing, communications and metrology. The individual IQT seminars prepared by Ph.D. students are as closely related to their real theses as possible. Important part of the seminar is a discussion among the students. The task was to enrich, possibly with a quantum layer, the current research efforts in ICT. And to imagine, what value such a quantum enrichment adds to the research. The result is sometimes astonishing, especially in such cases when quantum layer may be functionally deeply embedded. The final part was to write a short paragraph to a common paper related to individual quantum layer addition to the own research. The paper presents some results of such experiment and is a continuation of previous papers of the same style.

Proliferation of Internet of Things (IoT) devices has introduced new and complex security challenges. Due to constrained-resources, IoT devices are vulnerable to a wide range of attacks; including code injection, identity spoofing, supply chain tampering and many more. This study explores how Trusted Computing Concepts can enhance security in IoT devices. We will also develop a detailed threat model using PASTA modelling framework illustrating the attack vectors through which adversaries may compromise IoT devices. In response to these threats, we will propose a lightweight trusted computing architecture tailored for IoT deployments. The architecture will enable device identity provisioning, boot-time integrity verification, and runtime remote attestation while remaining efficient enough for application in low power microcontroller devices. Our findings highlight both the feasibility and limitations of trusted computing in IoT. We also identified future open research areas including attestation scalability, post-quantum readiness, and secure device lifecycle management. This study contributes to a foundational model for embedding verifiable trust in future IoT ecosystems.

Rozpowszechnienie urządzeń Internetu rzeczy (IoT) wprowadziło nowe i złożone wyzwania bezpieczeństwa. Ze względu na ograniczone zasoby, urządzenia IoT są podatne na szeroki zakres ataków; w tym wstrzykiwanie kodu, podszywanie się pod tożsamość, manipulacje łańcuchem dostaw, i wiele innych. W artykule przedstawiono, w jaki sposób koncepcje Trusted Computing mogą zwiększyć bezpieczeństwo urządzeń IoT. Pokazano szczegółowy model zagrożeń przy użyciu struktury modelowania PASTA ilustrujący wektory ataków, za pomocą których przeciwnicy mogą naruszyć bezpieczeństwo urządzeń IoT. W odpowiedzi na te zagrożenia proponowana jest lekka architekturę Trusted Computing dostosowana do wdrożeń IoT. Architektura umożliwia dostarczanie tożsamości urządzeń, weryfikację integralności w czasie rozruchu i zdalne poświadczanie w czasie wykonywania, pozostając jednocześnie wystarczająco wydajną do zastosowań w urządzeniach mikrokontrolerów o niskim poborze mocy. Podane przykłady podkreślają zarówno wykonalność, jak i ograniczenia Trusted Computing w IoT. Zidentyfikowano również przyszłe otwarte obszary badawcze, w tym skalowalność poświadczeń, gotowość postkwantową i bezpieczne zarządzanie cyklem życia urządzenia. Przedstawione rozważania mogą przyczynić się do stworzenia modelu fundamentalnego, który umożliwia osadzenie weryfikowalnego zaufania w przyszłych ekosystemach IoT.

The article explores the concept of smart villages, emphasising the integration of information and communication technologies (ICT), blockchain, and decentralised autonomous organisations (DAO) to improve sustainable management in rural communes. It highlights blockchain's role in decentralisation and process automation via smart contracts, offering benefits like improved transparency and reduced administrative costs. A hybrid approach that merges these technologies with traditional methods is recommended to optimise management while valuing human capital. This approach also requires investments in infrastructure, education, and legal adjustments to facilitate integration. A case study of the Pałecznica commune illustrates the successful implementation of a modern energy security management system that can be integrated with blockchain technology. Ultimately, the hybrid model ensures an effective transformation of public administration, increasing transparency, efficiency, and sustainable development in smart villages, as well as improving security in energy management.
