INTRODUCTION Each of us reacts to the world around and within us by sensing and actuating. When our hand is in contact with a hot object, we sense the heat, our brain sends a command, and our arm muscles actuate our hand away from the object. Similarly, because of internal sensing, we will tend to favor the burned hand until it has healed. As technology progresses, it becomes reasonable to ask,...

Techno-Social Pathology of Smart Elementary Schools for Girls in Qom from Teachers’ Perspective*   N. Naderi-Beni, Ph.D.** H. Khanifar, Ph.D.*** A. Ghofraani****    The importance of schooling in shaping the future of the society requires continuous evaluation/surveys and identification of shortcomings, especially in the newly invented smart schools. To engage in such a pathology the Tech...

Smart adaptive structures and structronic systems have been increasingly investigated and developed in the last two decades. Although smart structures made of piezoelectrics, shape-memory materials, electrostrictive materials, and electro-/magnetorheological fluids have been evaluated extensively, studies of magnetostrictive continua, especially generic mathematical model(s), are still relative...

In this study, control performance of a smart base isolation system consisting of a friction pendulum system (FPS) and a magnetorheological (MR) damper has been investigated. A fuzzy logic controller (FLC) is used to modulate the MR damper so as to minimize structural acceleration while maintaining acceptable base displacement levels. To this end, a multi-objective optimization scheme is used t...

This paper features the modelling and design of a type of multirate output feedback based controller (Fast Output Sampling Feedback FOS) to control the flexural vibrations of a smart flexible Timoshenko cantilever beam for a Single Input Single Output (SISO) case by retaining the first 2 dominant vibratory modes. Piezoelectric patches are bonded as sensor / actuator to the master structure at d...
