We implemented all-fiber delay line using linearly chirped fiber Bragg gratings (CFBG), which can be applicable for reflectometry or optical coherence tomography (OCT). Compared with the previously reported delay lines, the proposed fiber-based optical delay line has in principle novel advantages such as automatic dispersion cancellations without additional treatment and a gain in optical delay...

Recent US military events have produced a desperate need for language data in languages which have previously been given very little attention. Data resources for languages of military interest are often unavailable or insufficient to adequately develop new technologies. Realizing this need, the Defense Language Institute Foreign Language Center, has created a language data distribution center,...

This paper introduces a digital waveguide model of a flute which features a full set of finger holes of a real flute. The model responds correctly to real playing techniques, including the fingering combinations, overblowing, and vibrato. Many of the flute model parameters, such as the lengths of delay lines and finger hole filter parameters, have been computed from measurements taken from a re...

This work presents a low-dimensional physical model of the glottis in which a 2-D fold displacement representation allows to represent both the vertical and longitudinal displacements of the folds. We use a one-mass mechanical model, coupled to aerodynamic driving forces, and we use a delay line representation to account for the propagation of the displacement on the body-cover. The waveform is...

Linewidth variations within an external-cavity mode of a grating-cavity laser were measured with high accuracy using the self-homodyne technique with a short delay line. To our knowledge, this is the first time that these variations have been accurately measured. In our laser, we observed the linewidth to change by a factor of five from 30 kHz to more than 150 kHz when the laser was tuned over ...

New results on the physical limitations to position resolution in gas detectors for X-rays ( 3-20 due to the range of photoelectrons and Auger electrons are discussed. These results were obtained with a small gap detector in which position readout was accomplished by using a very low noise centroid finding technique. A description is given of position sensitive detectors for medium rates (a few...

An excitation model describes how the bow drives the oscillation of the string when moved across it. The string model describes the resonance of the string and usually includes a backfeed loop. The simplest string model is that of Karplus and Strong which consists of a feedback delay line with an order-2 lowpass. More complex string models take the two transverse oscillation modes of a string a...

Many applications in wireless sensor networks (WSNs) ( e.g. , traffic monitoring, environment surveillance and intruder tracking) rely heavily on the availability and accuracy of targets’ locations. Compressive sensing (CS) has been widely applied to localization as it asserts that a small number of samples will suffice for sparse or compressible signal recovery. Despite much progress in CS-bas...
