We investigated the correspondence between perceived meanings of smiles and their morphological and dynamic characteristics. Morphological characteristics included co-activation of Orbicularis oculi (AU 6), smile controls, mouth opening, amplitude, and asymmetry of amplitude. Dynamic characteristics included duration, onset and offset velocity, asymmetry of velocity, and head movements. Smile c...

The ability to create subsurface images whose amplitudes are proportional the elastic wavefield variations recorded within seismic data as a function of reflection angle is fundamental for performing accurate amplitude-variation-with-offset (AVO) analysis and inversion. A process that generates such commonly referred true-amplitude migration. We have determined how extended subsurface-offset im...

A customized IQ modulator driven by equal-amplitude binary signals for generating offset-free 16-quadrature amplitude modulation (QAM) is proposed and validated through simulations. The incorporation of tunable splitters demonstrates the feasibility of the transmitter and enables more efficient constellations such as hexagonal 16-QAM.

This research explores the representation and access of lexical form during spoken word recognition. Two experiments were conducted examining segmental priming effects. In the first set of experiments, a single fricative segment functioned as a prime to targets with either a matching or mismatching fricative in initial (Experiment 1a) or final (Experiment 1b) position. In the second set of expe...

A new algorithm to estimate amplitude, delay, phase, and frequency offset of a received signal is presented. The frequency-offset estimation is performed by maximizing, with respect to the conjugate cycle frequency, the projection of the measured conjugatecyclic-autocorrelation function of the received signal over the true conjugate second-order cyclic autocorrelation. It is shown that this est...

In this paper, a novel pulse shaping method is presented for Orthogonal frequency division multiplexing with offset quadrature amplitude modulation (OFDM/OQAM) systems. Designed as a linear combination of normalized Hermite functions, the proposed pulse is optimized with respect to interference caused by insufficient synchronization such as carrier frequency offset (CFO) and timing offset (TO)....

We demonstrated a method for the measurement of signed frequency offset between optical source and delay interferometer (DI) for 10 Gb/s DPSK signals based on asynchronous delay-tap sampling technique with a chromatic dispersion (CD) offset. The demodulated DPSK signals show asymmetrical property and amplitude shoulder appears on the waveforms with frequency offset and a fixed CD offset togethe...
