This book provides a concise and up-to-date overview of environmental noise control issues, utilizing specific case studies from India to help explore noise mapping and monitoring, impact analysis, and policy, among other relevant topics. The book provides an extensive review of recent studies, including references, and describes the latest noise monitoring structures. It also addresses heretofore under-emphasized topics, including but not limited to acoustic metrology, Multi Attribute Decision Making (MADM) techniques, and sound insulation utilizing passive control strategies.

In recent years, microfluidic devices with a large surface-to-volume ratio have witnessed rapid development, allowing them to be successfully utilized in many engineering applications. A smart control process has been proposed for many years, while many new innovations and enabling technologies have been developed for smart flow control, especially concerning “smart flow control” at the microscale. This Special Issue aims to highlight the current research trends related to this topic, presenting a collection of 33 papers from leading scholars in this field. Among these include studies and demonstrations of flow characteristics in pumps or valves as well as dynamic performance in roiling mill systems or jet systems to the optimal design of special components in smart control systems.
