Familial Mediterranean fever (FMF) is a recurrent episodic inflammatory disorder of unknown pathogenesis that occurs with high frequency in non-Ashkenazi Jews and Armenians. However, there are some differences in the clinical manifestations of FMF in these ethnic groups. FMF has been reported to be an autosomal recessive disease in non-Ashkenazi Jews, with(More)
Multiprocessor systems are high-performance systems that are making a rapid foray into the mainstream of computing. To realize their full potential, however, consideration must be given to their design. The design of the interconnection networks is particularly critical. Performance studies based on analytical and/or simulation models are conducted to(More)
Pneumatic muscle actuators (PMAs) have a high power to weight ratio and possess unique characteristics which make them ideal actuators for applications involving human interaction. PMAs are difficult to control due to nonlinear dynamics, presenting challenges in system implementation. Despite these challenges, PMAs have great potential as a source of(More)

This paper describes the design and capabilities of a noninvasive system to record the superficial temporal artery (STA) pulse pressure during diving scenarios in pilots. The Piezoelectric Pulse Pressure Monitoring System (P3) records the "best" waveform from an array of piezoelectric benders in contact with the skin above the STA during +1 Gz acceleration(More)
Multiprocessor systems have high speed and great flexibility. To realize the true potential of such systems, attention needs to be focused on their interconnection networks. Systematic performance evaluation studies are called for. There are two approaches to performance evaluation-analytic and simular. The analytic is usually complex and often intractable.(More)
INTRODUCTION A proof-of-concept demonstration is described in which a DC servomotor (simulating the quadriceps of a human operator) rotated a pulley 90 degrees (simulating knee extension). A pneumatic muscle actuator (PMA) generated an opposing force (antagonist) to the rotating pulley. One application of such a device is for use in microgravity(More)
Pneumatic muscle actuators (PMAs) offer significant advantages over more traditional actuators, which make them prime candidates in rehabilitation devices. A dynamic test station (DTS) is modified to demonstrate the use of a PMA for this application. The DTS includes two dynamic systems: a PMA and a DC servomotor. An overall transfer function was developed(More)
