      Adaptive disturbance rejection for disk drives using neural networks 

      Levin, J.; Pérez Arancibia, N. O.; Ioannou, Petros A.; Tsao, T. -C (2008)
      This paper presents the experimental verification of an adaptive feedforward disturbance rejection scheme for hard disk drives. The control scheme is shown to reduce the error during track-following by as much as 11.8%. ...

      Adaptive notch filter using real-time parameter estimation 

      Levin, J.; Pérez-Arancibia, N. O.; Ioannou, Petros A. (2011)
      The control of flexible systems is often difficult due to the exact frequencies of the elastic modes being hard to identify. These flexible modes may change over time, or vary between units of the same system. The variation ...

      Wideband BPF using quadruple-mode ring resonator loaded with short-circuited stubs and Γ-shaped band-stop sections 

      Arain, S.; Vryonides, P.; Abbasi, M. A. B.; Quddious, A.; Antoniades, Marcos A.; Nikolaou, S. (2017)
      In this letter, a compact, wideband bandpass filter with 31% 3-dB bandwidth, with very sharp roll-off characteristics, low insertion loss of 0.45 dB, high return loss greater than 25 dB, and improved out-of-band performance, ...
