- Tài liệuVirtual Reality and Metaverse: Impact on the Digital Transformation of Society Ii(MDPI, 2025) Vergara, DiegoVirtual reality, augmented reality, and the metaverse are no longer futuristic concepts—they are reshaping how society works, learns, and interacts. This Reprint compiles peer-reviewed studies exploring how diverse sectors such as healthcare, education, industry, and tourism are adapting to these immersive technologies. It offers a concise yet comprehensive view of the opportunities, challenges, and ethical considerations surrounding the digital transformation of society. This Reprint constitutes a significant resource for researchers, professionals, and curious minds interested in the future of human–technology interaction.
- Tài liệuTheoretical, Numerical and Experimental Studies on Clean Energy and Combustion(MDPI, 2025) Resende, Pedro; Ayoobi, Mohsen; Afonso, Alexandre M.This topic entitled “Theoretical, Numerical and Experimental Studies on Clean Energy and Combustion” addresses recent theoretical, numerical and experimental advances in clean-combustion-related applications to address climate change concerns while taking advantage of the higher energy density of hydrocarbon and other fossil fuels compared to batteries. With the recent advancements in computational capacities and the widespread applications of machine learning in engineering problems, the role of numerical methods is becoming more and more important to improve existing models or develop new models that can help researchers to better understand the underlying physics of combustion, their interaction with other physical phenomena such as turbulence, and their impacts on the performance of the related applications at both fundamental and practical levels. This topic aimed at highlighting the most recent advances in the development and application of such numerical methods, backed up with strong theories and/or experimental studies.
- Tài liệuAdvancements in Natural Language Processing, Semantic Networks, and Sentiment Analysis(MDPI, 2025) García-Méndez, Silvia; Costa-Montenegro, Enrique; Arriba-Pérez, Francisco DeThis Special Issue examines the intersection of NLP, semantic networks, and sentiment analysis, exploring how these technologies can contribute to more intelligent systems. The contributions gathered address, among other topics, the detection of irony and sarcasm, the generation of semantic explanations, the automatic construction of semantic graphs, the expansion of linguistic resources for underrepresented languages, and the use of large language models. Ultimately, this Special Issue aims not only to reflect the state of the art in the areas above but also to stimulate critical reflection on the methodological challenges, ethical implications, and interdisciplinary opportunities that arise at the intersection of computational linguistics and artificial intelligence.
- Tài liệuNonlinear Phenomena, Chaos, Control and Applications to Engineering and Science and Experimental Aspects of Complex Systems(MDPI, 2025) Balthazar, José Manoel; Tusset, Angelo Marcelo; Bueno, Átila Madureira; Colón, Diego; Varanis, MarcusThe aims of this Reprint are to publish theories and techniques in nonlinear systems, chaos and complexity to stimulate more interest in nonlinearity and complexity. This Reprint will focus on the recent developments, findings and progress in theories, principles, methodology and computational techniques in nonlinear systems and mathematics with engineering applications. This Reprint covers a broad scope of topics, including nonlinear dynamical systems and complex systems, and each one contributes theoretical analyses, practical applications, and numerical simulations to advance the understanding of complex nonlinear phenomena.
- Tài liệuModeling and Simulation in Engineering, 3rd Edition(MDPI, 2025) Petrescu, Camelia; David, ValeriuThe Special Issue, Modeling and Simulation in Engineering, belonging to the section Control Theory and Mechanics of the Journal Mathematics, publishes original research papers involving advanced simulation and modeling techniques. The present reprint, “Modeling and Simulation in Engineering, 3rd Edition” contains 8 papers accepted after peer review by recognized specialists in the field. The papers address different topics in engineering that use modeling and optimization as well as experimental and numerical methods based on state-of-the art devices and software. The subjects of the papers address technical problems such as error mitigation in ultra-wide-band range measurements, trajectory control of differential drive mobile robots, motion controllers for the trajectory of mobile robots, propellant distribution optimization in space exploration missions, modeling trafic flow as a tool for vehicle adaptive cruise control systems, monitoring vehicle convoys using a drone-based platooning system, communication and navigation systems for Earth-Moon communication and rover movement on the Moon’s surface and solving optimal control problems using a new state parametrization method. We hope that the papers selected for this issue will attract a significant audience in the scientific community and will further stimulate research involving modeling and simulation in mathematical physics and in engineering.
