Immobilization of stimulus-responsive systems on solid surfaces is beneficial for controlled signal transmission and adaptive behavior while allowing the characterization of the functional interface with high sensitivity and high spatial resolution. Positioning of the stimuli-responsive units with nanometer-scale precision across the adaptive surfa...
Electrical Submersible Pump (ESP) is one of the efficient lifting methods for oil, gas and water which is widespread around the world. ESP System (ESPS) consists of several components: surface components and underground components. The surface components include an electric power supply, a transformer, a control board, and a control valve. The unde...

The ability to use actuator and load models online in combination with experimental data becomes increasingly important in future electrical drives. Amongst the applications of such online model in torque and flux controllers, model predictive control (MPC) has gained increasing interest, allowing to deal in real time and in a suboptimal way with d...
In this article, a fault tolerant deadbeat controller is proposed, which is able to compensate for both partial and uniform demagnetization faults in axial flux permanent-magnet synchronous machines with double rotor, even with asymmetric defects in both rotors. For this purpose, the system model used by the deadbeat controller is equipped with a l...
Biohybrid microbots with small body size, have been integrated successfully into miniaturized system/process with confined geometry and/or closed environments. One such specific case is the construction of microbot, composed of microswimmer with other functional nanomaterials that allow non-conventional taxis-based strategy to guide the motion of t...

Flagella, the primary means of motility in bacteria, are helical filaments that function as microscopic propellers composed of thousands of copies of the protein flagellin. Here, we show that many bacteria encode “giant” flagellins, greater than a thousand amino acids in length, and that two species that encode giant flagellins, the marine γ-proteo...
As interturn short fault (ISF) in a permanent-magnet synchronous machine (PMSM) degrades its energy efficiency and may cause other problems, accurate fault diagnosis for the PMSMs is necessary. In this paper, we present a method that uses voltage and current residual components to diagnose the phase and the severity of the ISF in PMSMs. A faulty-wi...
Machines have greatly contributed to the human civilization, enabling tasks beyond our capacities for improved quality of life. Recently, the progress in nanotechnology has triggered to build a miniaturized machine of nanoscale. In this context, synthetic nanomotors have gained considerable interest because of their great promise for diverse applic...
