Dynamic modelling and active vibration control of a submerged rectangular plate equipped with piezoelectric sensors and actuators
Moon K. Kwak,Dong-Ho Yang +1 more
TL;DR: In this article, a multi-input, multi-output positive position feedback controller was designed by taking the natural vibration characteristics into account and was then implemented by using a digital controller.

Advantages of using command shaping over feedback for crane control
TL;DR: In this paper, the authors explore the problems with using feedback for crane control, which include the difficulty in sensing the crane payload, widely varying system dynamics, and human-operator compatibility.
Journal ArticleDOI
Vibrational Characteristics of Bone Fracture and Fracture Repair: Application to Excised Rat Femur
TL;DR: It is concluded that the proposed radiation force method may be used as a remote and noninvasive tool for monitoring bone fracture and healing process, and the use of focused ultrasound enables one to selectively evaluate individual bones.

Multi-element acoustic recharging system
TL;DR: In this article, an acoustic energy delivery system for delivering acoustic energy to an implantable medical device (IMD) is presented, which includes an IMD having a power source and an energy delivery device.
Journal ArticleDOI
In-plane vibrations of non-circular arcs of non-uniform cross-section
TL;DR: In this paper, the title problem is solved by using polynomial coordinate functions and the Ritz method to generate the frequency equation, and the agreement with results available in the literature or with eigenvalues determined by means of a finite element code is good from an engineering viewpoint.
