The heart rate variability (HRV) is the variation in the pulsing frequency of the human heart. Measuring this parameter can reveal important information on the real-time interaction between the autonomic nervous system and the cardiocirculatory system. It can provide useful insight on an individual's state of stress or well being even outside a clinical setting, thanks to inexpensive and unobtrusive...
With rapid advances in VLSI, technology has enabled us to reduce the minimum feature sizes of sub-quarter microns and the switching times to tens of picoseconds or even less. The trend in VLSI industry is moving toward designs that are more complex, higher operating frequencies, sharper rise times, shrinking device sizes and low power consumption. Although the device noise sources (i.e. shot noise,...
Cognitive radio with its capability to sense the radio environment and dynamically access the vacant spectrum opportunistically, is an important technology to improve the efficiency of current spectrum utilization. In this paper, a cooperative wideband spectrum sensing approach based on subspace methods is proposed to estimate the number of primary user signals present in the band of interest and...
Soft errors have emerged as an important reliability challenge for nanoscale very large scale integration designs. In this paper, we present a fast and efficient soft error rate (SER) analysis methodology for combinational circuits. We first present a novel parametric waveform model based on the Weibull function to represent particle strikes at individual nodes in the circuit. We then describe the...
