On the characterizations of some distinguished subclasses of Hilbert space operators. Acta Scientiarum MathematicarumActa Scientiarum Mathematicarum. 2018;84 :611-627.
AbstractIn this note, we present several characterizations for some distinguished classes of bounded Hilbert space operators (self-adjoint operators, normal operators, unitary operators, and isometry operators) in terms of operator inequalities.

Characterizing Slow state Near Si-SiO2 in MOS structure, ISSN / e-ISSN 1042-6507 / 1563-5325. Phosphorus Sulfur and Silicon and the Related ElementsPhosphorus Sulfur and Silicon and the Related Elements. 2018;Volume 193 :pp.88-91.
AbstractThe Equilibrium Voltage Step (EVS) technique has been used for extraction of depth and energy concentration profile of traps situated in the oxide of a lightly stressed metal-oxide-semiconductor (MOS) structure. This has been achieved up to the very near Si-SiO2 interface. The results are discussed and compared with those obtained using charge pumping (CP) technique. A good agreement is achieved between the trap densities extracted using the two methods even though differences in the shape of the profiles can be observed. The results also very well agree with those published previously using current deep level transient spectroscopy (C-DLTS).

Comparative study between luenberger observer and extended kalman filter for fault-tolerant control of induction motor drives. International Information and Engineering Technology AssociationInternational Information and Engineering Technology Association. 2018;73 N 2 :29-36.
AbstractIn this paper, a robust active fault tolerant control (AFTC) scheme is proposed for induction motor drives (IMD) via input-output linearization control (IOLC) and nonlinear observer. In order to estimate the states and to reconstruct the faults, two different observers are used; a Luenberger observer (LO) and an extended kalman filter (EKF). Further we introduce feedback linearization strategy by choosing the output function as the rotor speed and flux square. To provide a direct comparison between these FTCs schemes, the performance is evaluated using the control of IMD under failures, variable speed, and variable parameters, finally the obtained results show that the proposed controller with the proposed observers provides a good trajectory tracking, and these schemes are robust with respect to faults, parameter variations, and external load disturbances for induction motor drive system.
