Emerging Trends in Engineering and Technology (Volume - 6), edited by Mohit Bajpai, Dr. A.V. Sudhakara Reddy, and Dr. V. Lakshmi Devi, features six interdisciplinary chapters covering wireless communication, smart energy systems, urban history, machine learning, and medical imaging. Topics include Mobile Ad-hoc Networks (MANETs), cascaded asymmetric multilevel inverters, architectural and cultural study of Fatehpur Sikri, smart city planning using big data and ML, fake audio detection via machine learning, and classification of COVID-19 and pneumonia chest X-rays using CNNs. This volume blends technical, historical, and diagnostic perspectives, integrating MATLAB simulations, AI-based classification models, and sustainable urban computing. It is an essential resource for researchers, engineers, urban planners, and students seeking applications of embedded systems and AI in communication networks, medical diagnostics, historical analysis, and smart infrastructure.
