Mechanical engineering is an incredibly broad field, and provides the engineer a number of different areas in which to work. Following areas included in mechanical engineering are Applied Mechanics, Fluids Engineering, Heat Transfer, Bioengineering, Tribology, Energy Conversion, Internal Combustion Engines, Fuels & Combustion Technologies, Energy Resources, Nuclear Engineering, Solar Engineering, etc. A process engineer changes materials from one form to another so that they can be used in new and interesting ways. A mechanical engineer will design and build the machines that heat, cool, liquefy, harden or soften substances. Dynamic systems need to be controlled. Typical applications of DSC include novel transducer designs, biomechanics at the cellular and human scale, dynamics and control of power and vehicle systems, and innovations in signal and information theory. These engineers are needed in a vast number of areas — aerospace and transportation, biomedical equipment, production machinery, energy and fluid power systems, expert systems and environmental systems. The journals provide forum and motivates scientists, researchers, academics, engineers, and practitioners in all aspects to share their professional and academic knowledge in the fields computing, engineering, humanities, economics, social sciences, management, medical science, and related disciplines. Online Journals also aims to reach a large number of readers worldwide with original and current research work completed on the vital issues of the above important disciplines. The journals permit all readers to read, view, download and print the full-text of all published articles without any subscription or restrictions.
