A fractional order PID control strategy in active magnetic bearing systems
Alexandria Engineering Journal, 2018 Active Magnetic Bearings (AMBs) are broadly utilized for high angular speed machines such as turbo-machinery, compressors and high speed motors. In AMBs, the rotating parts run without physical contacts with the moving parts.

Advanced Functional Materials, EarlyView.The layer‐by‐layer (LbL) assembly of coordination solids, enabled by the surface‐mounted metal‐organic framework (SURMOF) platform, is on the cusp of generating the organic counterpart of the epitaxy of inorganics. The programmable and sequential SURMOF protocol, optimized by machine learning (ML), is suited for accessing high‐quality thin films of ...

, 2013 Magnetism is a class of physical phenomena that includes forces exerted by magnets on other magnets. It has its origin in electric currents and the fundamental magnetic moments of elementary particles. A bearing is a machine element that constrains relative motion between moving parts to only the desired motion.
