Recent advances in the synthesis of superconducting cuprates, such as Ba sub 2 YCu sub 3 O sub 7, have profound scientific and technological implications which have only begun to be explored. This talk will focus on current results regarding the occurrence of high-transition- temperature superconductivity, the physical properties of ...

A fiber-optic sensor system (FOSS) consists of an optoelectronic hub, optical fibers, and an optical sensor or sensor network. The hub contains optical sources, detectors, optical and electrical components, and an output or output interface. The sensors are either extrinsic (optrodes) or intrinsic (inherent to the fiber itself).

Communication between people seems to occur most naturally via speech. Although desirable, it is not as easy today to have the same quality communication between people and computers. Yet, recent advances in automatic speech recognition, speech coding and synthesis and text- to-speech synthesis technologies offer new opportunities for the performance ...

As modern factories try to implement Computer Integrated Manufacturing (CIM), they are discovering that the cost estimates of the computers and data communication equipments range from 25% to 50% of the total cost of an automated factory. Therefore it is of increasing importance to understand the performance of these systems, ...

We have designed, built, and performed the first experiments on the X16A beamline at NSLS, Brookhaven. The components are (in order) a 60 cm toroidal focusing mirror, two crystal Si(111) vacuum monochromator, ultra-high vacuum sample preparation and analysis chamber, and 4-circle diffractometer. The precision manipulation of the samples in vacuum ...

We report on an optical transmission experiment using four in-line optical amplifiers. With a net gain of 58 000 X (47.7 dB) from the amplifiers, we were able to increase the longest non- regenerated transmission distance to 372 km. the system penalty associated with the amplifiers was only 1.5 dB.

One of the goals of artificial intelligence is to simulate the human decision making process. Ads's concurrency and its associated language features controlling nondeterminism in real time systems allow a partial simulation of this decision making process. A more complete specification of the human thought process requires new language features ...

The theoretical benefits of thick tungsten plugs in windows, i.e. increased reliability, reduction in layout area, and its diffusion barrier properties, have been pointed out in the past. However, process integration concerns over contact resistance variations, increased junction leakage, loss of selectivity, oxidation resistance, and adhesion problems of tungsten to ...

Small geometry, high aspect ratio Al,Si/Si contacts to shallow junctions are susceptible to: (a) opens due to inadequate step coverage of Al,Si, (b) junction leakage due to preferential dissolution of Si into Al, and (c) high contact resistance due to silicon precipitation in the windows.

Providing a supportive environment for computer system testers results in substantial productivity improvement. Both the physical environment and the conceptual environment in which testers work need attention. The physical environment provides tools to encourage test automation and good data collection. The conceptual environment provides tools to enhance measurement of product ...

A bivariate (multivariate) double exponential distribution can be generated using differences of cross products of bivariate (multivariate) normal random variables. This distribution possess desirable dependence properties in that it has linear regressions and is indexed by a single correlation parameter whose extreme values correspond to the Frechet bounds. Also, it ...

This paper describes the reestimation algorithm and its performance when applied to recognize spoken versions of the English alphabet and the digits. In our experiments, the system was trained using speech material from four talks (two males and two females) and tested using different utterances from the same speakers. Preliminary ...
