The electro-hydraulic servo system (EHSS) demonstrates numerous advantages in size and
performance compared to other actuation methods. Oftentimes, its utilization in industrial …

Grinding plays an important role in the production of fine finishing surfaces. However,
generation of substantial amount of energy through rubbing, plowing and cutting actions in the …

Zirconia bioceramics has tremendous potential in medical applications owing to biocompatibility
and high mechanical properties. Meanwhile, thermal damage and surface defects limit …

Subsurface damage (SSD) is a predominant type of damage in grinding process of optical
materials with direct effect on the optical components performances. A series of cup wheel …

Abstract Knowledge of material removal behavior and generated surface characteristics are
crucial to improve grinding performance. A finite element model was developed using a …

Damage detection using the Electro-Mechanical Impedance method (EMI) is based on
measuring the electrical impedance spectrum of piezoelectric wafer active sensors (PWAS) …

Grinding is one of the most complex and precise machining operations, with the performance
of the grinding wheel being heavily reliant on its surface conditions. Removed chips tend to …

… Without the remarkable assistance of my supervisors, Hamed Adibi and Seyed Mehdi Rezaei,
neither this work nor the research supporting it would have been feasible. From our initial …

Control of piezoelectric actuators is under the effects of hysteresis that could affect actuators
micropositioning accuracy. In this paper a modified Prandtl–Ishlinskii (PI) operator and its …

In the present work, a novel approach is proposed to produce a functional surface with
hydrophobic property by grinding process with rearranging the position of abrasive particles on …
