The performances of four refractive concentrators in enhancing LED source-to-multimode fiber coupling are compared on the basis of improvement of coupling efficiency and relaxation of source-fiber mechanical alignment tolerances. For a core-to-source

In this presentation, we compare the gain in performance offered by combing the result of a ground-penetrating radar, an electromagnetic induction metal detector, and a magnetometer (MAG) against the performance offered by any one of these sensors al

An ultradense (> 10/sup 19/e/sup -//cm/sup 3/), low-temperature (approx. 20 eV), Z-pinch plasma has been used for CO/sub 2/-laser-plasma interaction experiments at 10.6..mu..m. Anomalous transmission or radially incident, intense (approx. 10/sup 11/

This paper describes a single-board implementation of an isolated word recognizer based on the principles of linear predictive coding (LPC) and dynamic time warping (DTW). The recognizer requires only a serial (RS-232) terminal, power supply, and mic

Speech processing can exploit the growing overlap of information processing and information transportation typical in many of today's advanced workstations that combine computing and telephony. With speech input and output capabilities added, the ubi

The apparent complexity of the laser‐plasma coupling in laser fusion target irradiation has stimulated the need for carefully controlled experimental studies of the laser‐plasma interaction at the critical surface. A helium Z pinch has been const

A method for aligning the optics of a pulsed high‐power positive branch unstable resonator is described. The procedure relies on the distribution of the output beam and is thus independent of a separate alignment laser, allowing systematic and rapi
