A burst-mode clock recovery circuit with a novel dual-mode structure is presented. It utilizes two gated-oscillators to align recovered clock edges to data. It can operate in double data-rate mode in which both rising and falling edges of recovered clock are used. To enable this, gated-oscillator reset-phase control scheme is introduced to switch the starting phase of gated-oscillator dynamical...

In this paper we present a Two-Phase LMR-RC Tagging scheme to perform Chinese word segmentation. In the Regular Tagging phase, Chinese sentences are processed similar to the original LMR Tagging. Tagged sentences are then passed to the Correctional Tagging phase, in which the sentences are re-tagged using extra information from the first round tagging results. Two training methods, Separated Mo...

We consider the model of a nondegenerate parametric oscillator, in the adiabatic limit of strongly damped pump mode, and find an exact analytic solution for the joint two-mode Wigner function in the steady-state regime. The one-mode Wigner functions for the individual signal and idler modes are derived as well. This gives an explicit and complete phase-space representation of this two-mode none...

background & aim: the risks of maternal mortality and morbidity associated with cesarean delivery are three and two times higher than vaginal delivery, respectively. the majority of cesarean sections are due to failure to progress in labor. one of the common risk factors for failure to progress is small maternal body size. cormic index is an indicator of body composition assessment, which estim...

We report new limits on the phase coherence of the ultrafast mode-locking process in an octave-spanning Ti:sapphire comb.We find that the mode-locking mechanism correlates optical phase across a full optical octave with less than 2.5 microHZ relative linewidth. This result is at least two orders of magnitude below recent predictions for quantum-limited individual comb-mode linewidths, verifying...

in this study, we present a mrcpsp/max (multi-mode resource-constrained project scheduling problem with minimum and maximum time lags) model with minimization tardiness costs and maximization earliness rewards of activities as objective. the proposed model is nearby to real-world problems and has wide applications in various projects. this problem is not available in the literature exactly and ...

this study aims to compare the effects of four types of ffi on second language vocabulary learning. to do so, the study adopted a quasi-experimental pretest-posttest design, including five groups, each receiving a distinct treatment. the participants were 80 fourth-grade male students ranging in age from 17 to 19. before the treatment phase, the participants took a researcher-made test of vocab...

Burst-mode data is obtained when a SAR system is operated in ScanSAR mode. Missing data in the burst gaps makes it difficult to use traditional phase-preserving algorithms to produce single look complex (SLC) data. In this paper, three phase-preserving algorithms for burst-mode data compression are examined and compared to find the best algorithm for precision processing applications such as in...
