This paper presents numerical simulation of plate wave modes in thin stainless steel plates using a racetrack spiral coil electromagnetic acoustic transducer (EMAT), which works under the principle of acousto-elastic effect, called Lorentz force mechanism. EMATs are useful for non ... Read More
It is very difficult to measure the global properties of heterogeneous and anisotropic materials like composites and sandwich structures. When designing composite sandwich applications, the elastic properties are required to perform structural stiffness and strength calculations. ... Read More
This paper presents an ongoing effort, motivated by developing self-contained sensors for structural health monitoring of inflatable structures, to model the process of extracting useable electrical power from the mechanical vibrations of thin, prestressed membrane structures. Energy ... Read More
Microelectromechanical systems (MEMS) are becoming more prevalent in today’s space technologies. The Visible Nulling Coronagraph (VNC) instrument, being developed at the NASA Goddard Space Flight Center, uses a MEMS Mirror to correct wavefront errors. This MEMS, the Multiple Mirror ... Read More
The onshore wind turbine industry must overcome many technical, commercial, and environmental difficulties. A significant element for planning consent is operational noise. Acoustic limits are strictly enforced and can lead to near-neighbour complaints as well as contractual disputes. ... Read More
AlGaN/GaN heterostructures are unique because the 2DEG at the interface is created by the difference in polarization properties of the AlGaN and the GaN layers; not due to intentional doping. In this work, a 3D model of an electrostatically actuated micro cantilever has been developed ... Read More
Microarrays are extensively used in modern biology as tools of multiplexed, high throughput analysis to study thousands of genes and their expression inside cells at once [1]. The basic principle of a microarray is quantitative detection of fluorophore tagged DNA. Use of this method ... Read More
The aim of this paper is to determine the location of the “sweet spot” for a selected cricket bat commonly used in the sport. Knowledge of the “sweet spot” is important in delivering a shot that utilizes the optimal zone of the bat that corresponds to the maximum power of the stroke. A ... Read More
This work describes the design and optimization of three prototypes of microelectromechanical systems (MEMS) capacitive accelerometer-based middle ear microphone. The microphone is intended for middle ear hearing aids as well as future fully implantable cochlear prosthesis. The analysis ... Read More
Vibrating mechanical tank components, such as quartz crystals and surface acoustic wave (SAW) resonators with Q’s in the range of 10e3–10e6, are widely used to implement high-Q oscillators and band pass filters in the radio frequency (RF) and intermediate frequency (IF) stages of ... Read More
