372   Single mode fiber based polarization sensitive optical coherence tomography using a swept laser source Single mode fiber based polarization sensitive optical coherence tomography using a swept laser source    2011 We report the development of a near real time single mode fiber-optic based polarization sensitive optical coherence tomography (PSOCT) setup utilizing a swept source. The setup has a polarization modulator (PM) and polarizer in a sample arm to serve as a polarization state generator and analyzer. Since only intensity information is used to retrieve the polarization parameters of the sample, the problem of phase jitters present in the swept source is avoided. Further, the use of polarization ele... 查看全文

373   A Fast Iterative Shrinkage-Thresholding Algorithm for Linear Inverse Problems A Fast Iterative Shrinkage-Thresholding Algorithm for Linear Inverse Problems Amir Beck;Marc Teboulle    0 We consider the class of iterative shrinkage-thresholding algorithms (ISTA) for solving linear inverse problems arising in signal/image processing. This class of methods, which can be viewed as an extension of the classical gradient algorithm, is attractive due to its simplicity and thus is adequate for solving large-scale problems even with dense matrix data. However, such methods are also known to converge quite slowly. In this paper we present a new fast iterative shrinkage-thresholding algor... 查看全文

375   Resolution For Synchrony And No Learning Resolution For Synchrony And No Learning Full Version Nalon, C. Nalon, C. Dixon, M. Fisher    2004 We present a clausal resolution-based method for temporal logics of knowledge with synchrony and no learning. This and related logics admit axioms which include operators from both the temporal and epistemic logics, which enable the description of how knowledge evolves over time. Instead of proposing new resolution rules, further information is added to the set of clauses in order to deal with this particular interaction. We give outline of the proofs of soundness, termination, and complete... 查看全文

378   High-speed optical star network using TDMA and all-optical demultiplexing techniques High-speed optical star network using TDMA and all-optical demultiplexing techniques    1996 The authors demonstrate the use of time-division multiplexing (TDM) to realize a high capacity optical star network. The fundamental element of the demonstration network is a 10 ps, wavelength tunable, low jitter, pulse source. Electrical data is encoded onto three optical pulse trains, and the resultant low duty cycle optical data channels are multiplexed together using 25 ps fiber delay lines. This gives an overall network capacity of 40 Gb/s. A nonlinear optical loop mirror (NOLM) is used to ... 查看全文

381   Point Defects in Hard-Sphere Crystals† Point Defects in Hard-Sphere Crystals† Sander Pronk and Daan Frenkel*    2001 We report numerical calculations of the concentration of interstitials in hard-sphere crystals. We find that in a three-dimensional fcc hard-sphere crystal at the melting point, the concentration of interstitials is 2.7(4) × 10-8. This is some 3 orders of magnitude lower than the concentration of vacancies. A simple, analytical estimate yields a value that is in fair agreement with the numerical results. 查看全文

382   SIMULATION OF TIMING AND CARRIER RECOVERY USING SYSTID. SIMULATION OF TIMING AND CARRIER RECOVERY USING SYSTID.    1979 The performance of digital carrier modulation schemes (such as, QPSK, OQPSK) depend on the accuracy of the timing and carrier phase recovery networks used in the receiver. This paper describes a computer simulation model which can be used for analyzing the performance of these networks. This model is applied to a particular modem which uses a quadrupling circuit and tuned filter for estimating the carrier phase, and a delay multiply and filter combination for clock recovery. The statistics of th... 查看全文

383   High speed semiconductor lasers and applications in subpicosecond mode locking High speed semiconductor lasers and applications in subpicosecond mode locking    1989 Active mode locking of high-speed semiconductor lasers has produced subpicosecond pulses. One of the major applications of these short-pulse sources is time-division multiplexing. In principle, a system of 20 mode-locked lasers at 20-GHz connected to external modulators at the output of each laser should result in a system operating at 400 Gb/s. The major problems in implementing such a system have recently been addressed. First, the relative jitter between the sources must be much less than the... 查看全文

385   Long- and short-term affective states in happiness: Age and sex comparisons Long- and short-term affective states in happiness: Age and sex comparisons Albert Kozma, Roberto Fazio, M. J. Stones;T. E. Hannah    1992 Data from 690 persons in three adult age groups were used to evaluate the generality of a componential model of happiness (Kozma et al., 1990). The model postulates that long- and short-term affective states combine in an additive manner to produce current happiness. The short-term components should be more susceptible to environmental manipulation than the long-term ones and should change more readily with an appropriate experimental manipulation. Subscales of the Memorial University Mood Scale... 查看全文
