Report of a review of the NSF ocean research section
(The Oceanography Society, 1996)
EVERY THREE YEARS a Committee of
Visitors is formed by the National Science
Foundation (NSF) Advisory Committee
on Geosciences to review the various
aspects of NSF funding in the
Directorate for Geosciences. This year ...
Time-varying effects and averaging issues in models for current-mode control
(Institute of Electrical and Electronics Engineers (IEEE), 1997-05)
This paper investigates issues in modeling of current-mode control in converters. The effects of the current-sampling intrinsic to current-mode control are analyzed, and inadequately recognized limitations of linear ...
Design and evaluation of a cellular rectifier system with distributed control
(Institute of Electrical and Electronics Engineers (IEEE), 1999-06)
This paper presents the design and experimental evaluation of a six-cell 6 kW cellular (parallel) rectifier system which operates at nearly unity power factor. The cellular rectifier system implements both distributed load ...
High Performance, Point-to-Point, Transmission Line Signaling
(Hindawi Publishing Corporation, 1998-01)
Inter-chip signaling latency and bandwidth can be key factors limiting the performance of large VLSI systems. We present a high performance, transmission line signaling scheme for point-to-point communications between VLSI ...
Identification and Characterization of a Bacterial Chromosome Partitioning Site
(Elsevier, 1998-03)
We have identified a DNA site involved in chromosome partitioning in B. subtilis. This site was identified in vivo as the binding site for the chromosome partitioning protein Spo0J, a member of the ParB family of partitioning ...
Manufacturing flow line systems: a review of models and analytical results
(Springer-Verlag, 1992-03)
The most important models and results of the manufacturing flow line literature are described. These include the major classes of models (asynchronous, synchronous, and continuous); the major features (blocking, processing ...
Lead User Analyses for the Development of New Industrial Products
(Institute for Operations Research and the Management Sciences (INFORMS), 1988-05)
Recently, a “lead user” concept has been proposed for new product development in fields subject to rapid change (von Hippel [von Hippel, E. 1986. Lead users: A source of novel product concepts. Management Sci. 32 791–805.]). ...
Two radical neuron doctrines
(Cambridge University Press, 1999-10)
Two radical neuron doctrines must be distinguished--strong and weak. G&S direct much of their attack at the former--but the Churchlands only hold the latter. The weak radical neuron doctrine remains a serious possibility.
Laser Excitation Spectra and Lifetime Measurements of the CO d(³Δi) State
(Hindawi Publishing Corporation, 1991-01)
CO in a supersonic pulsed beam is excited to the d³Δi state by VUV photons generated in a nonlinearfour-wave mixing scheme. An excitation spectrum of the CO d³Δi (ν′ = 20, J′ = 1–3) is obtained at aresolution of 0.8 cm⁻¹ ...
Pressure in a fluid‐filled borehole caused by a seismic source in stratified media
(Society of Exploration Geophysicists, 1996-01)
A method for numerically simulating hydrophone vertical seismic profiles (VSP) and crosswell data measured in a fluid-filled borehole (either open or cased) embedded in stratified media is presented. The method makes use ...
