This paper reports on the design of an integrated transceiver that supports SINCGARS (Single Channel Ground-Airborne Radio System). Utilizing both transistors and microelectromechanical systems (MEMS), the circuit transmits preprocessed discrete-time baseband data and receives RF passband signals that are mixed to 100kHz and sampled by a fast ADC for off-chip demodulation. By using micromechan...

We investigate the mechanical property predictions for a three-phase viscoelastic (VE) composite by the use of two micromechanical models: the original Mori–Tanaka (MT) method and an extension of the Mori–Tanaka solution developed by Benveniste to treat fibers with interphase regions. These micro-mechanical solutions were compared to a suitable finite-element analysis, which provided the benchm...

Using electromechanical technique, various conductive carbon fibers and graphite and steel filaments/epoxy micro-composites were evaluated by measuring electrical resistivity to investigate the interfacial properties including the microfailure modes and interfiber distance effect with a aid of acoustic emission (AE). Micromechanical techniques, such as pull-out and fragmentation tests, and elec...

Third-order, high-Q, micromechanical bandpass filters comprised of three ratioed folded-beam resonators coupled by flexural mode springs are demonstrated using an integrated circuit compatible, doped polycrystalline silicon surfacemicromachining technology. A complete design procedure for multiresonator micromechanical filters is presented and solidified via an example design. The use of quarte...

We discuss biologically inspired devices and architectures for acoustic processing microsystems. We exploit state of the art integrated microsytems technologies to heterogeneously integrate electronics and micromechanical structures for acoustic sensing and signal processing.

We consider the possibility of using a micromechanical gate electrode located just above the island of a single-electron transistor to measure directly the fluctuating island charge due to tunnelling electrons.

INTRODUCTION The lasting integrity of the bond between the bone and the cement is essential to the success and longevity of cemented total hip replacements [1]. It is well known how the strength of the bone-cement interface is related to the amount of bone interdigitated with the cement [2] and although numerous studies have been carried out on bone-cement interfacial strength at the continuum ...
