    Adaptive regional feedback control of robotic manipulator with uncertain kinematics and depth information by Li, X., Cheah, Chien Chern

    Published 2014
    “…While much progress has been achieved in taskspace control of robot, existing task-space sensory feedback control methods fail when the sensor is out of working range. In this paper, we propose an adaptive regional feedback control strategy that enables the robot to start from an initial position outside the field of view and leave the field of view during the movement. …”

    Erasure temperature measurements of heat assisted magnetic recording media by Chen, Y. J., Yang, H. Z., Leong, S. H., Cher, K. M., Hu, J. F., Sethi, P., Lew, Wen Siang

    Published 2015
    “…Magnetic force microscopy (MFM) and magnetic Kerr microscopy observations of the scanning laser induced degradation/erasure/demagnetization of the pre-recorded magnetic patterns on disk media (over a wide area of a few hundreds of μm2) show that the magnetic (MFM and Kerr signal) amplitude of the pre-recorded magnetic patterns decreases slowly with increasing laser power (Pw) (/temperature rise) for Pw ≲ 66 mW and then drops sharply to nearly zero for Pw ≥ ∼72 mW (the laser power corresponding to complete thermal erasure when the media temperature is ∼Te). It was further found that this trend of magnetic amplitude reduction with increased Pw is similar to that from magnetic amplitude decrease of pre-recorded magnetic patterns with increased bulk heating temperature. …”
