A prototype system, developed at AT&T, supports a premiere ISDN customer's network management needs by exporting selected features from existing Bell Operating Company Element Management Systems. The prototype provides a major step towards the goal of end-to-end network management by combining diverse functions to a single integrated user interface.

Special considerations apply to the measurement of two-dimensional (2-D) structure factors. First of all, there is strictly no well-defined, integrated intensity because the data are continuous functions of perpendicular momentum transfer.

Magnetic fluctuations in the hydromagnetic energy band ~0 to ~0.05 Hz are examined at magnetospheric cusp latitudes during two times when ionspheric signatures of possible flux-transfer events were evident in the data.
High Performance Ga sub (0.4) In sub (0.6) As/Al sub (0.55) In sub (0.45) As Pseudomorphic Modulation-Doped Field-Effect Transistors Prepared by MBE

This tutorial reviews the basic simulations in source-drain- base parasitics and source-drain-base contacts as devices are scaled to the submicron regime. The major portion of the paper reviews the various proposals to provide local interconnect layers which interface with the source-drain-base and from which all contact windows to metal- 1 ...

This paper discusses a light-traffic approximation for multi- class queues: If the arrival rate of a class upon one visit to the queue is a small proportion of the total arrival rate there, then the departure process for that class from that visit should be nearly the same as the ...

This series of three lectures will describe the current knowledge of the computational complexity of the Riemann zeta function. New algorithms will be presented which allow the efficient computation of large numbers of values of the zeta function simultaneously.

This talk will survey the latest results on knapsack-type public- key cryptosystems, with special emphasis on low density attacks. The only such cryptosystem that is still unbroken, due to Chor and Rivest, will also be presented.

This talk will describe several new algorithms in number theory. They all have the common feature that they deal with finite precision computations of analytic functions. While this is quite natural in some settings, i others it is rather surprising, since these algorithms are used to compute exactly some integer-valued ...

Four commercial samples of tungsten hexafluoride were analyzed for purity by Fourier transform mass spectrometry. Impurities were identified by accurately measuring the masses of the ions observed. Quantitation was based on ion intensities, which were corrected for ionization cross sections of the molecule, fragment ion abundance, and diffusion rate into ...

A new synthetic approach has been developed for the synthesis of new and existing silicon and germanium metal-metal bonded polymers. The method employs high intensity ultrasound to instantaneously emulsify liquid alkali metal alloys during their reaction with ethereal solutions of R sub 1 R sub 2 MCI sub 2 (R ...

Flexible and Powerful operations features are needed for modern lightwave transmission systems. With the evolution from point- to-point systems which simply transmit digital signals form one central office to another to interconnected networks including optical transmission, multiplexing, add/drop, and electronic cross-connect, there is a need for systems to provision, maintain, ...

In conventional computer systems, upgrading the system to provide more features and higher performance often involves archiving software, taking the system down, replacing the system and making old software packages compatible with the new system.
Hot Electron Transport in the AlSb/InAs/GaSb Double Heterostructure Prepared by Molecular Beam Epitaxy
- Chiu T.

Thin film epitaxial crystal growth and continued reduction in device dimensions has led to the emergence of a class of structures in which charge transport is non-diffusive. For example, there is interest in developing ultrafast electronic and opto-electronic devices in semiconductors utilizing hot electron transport over length scales much smaller ...

Butadiene has been polymerized in polystyrene with several Ziegler-Natta catalysts via an in-situ technique. We have found that the structure of the polybutadiene is different when polymerization occurs within a solid below its glass transition temperature. For catalysts containing halide ligands, a significant amount of cyclotrimerization of butadiene is observed ...
