True parallel processing in artificial neural networks
(Emerald Group Publishing Limited, 2001)
The area of artificial neural networks, which dates back to the early twentieth century, could only offer positive contributions to technology after the back-propagation algorithm was proposed in 1986. In this note an ...
Microchip isoelectric focusing using a miniature scanning detection system
(John Wiley & Sons Ltd., 2001)
A miniature scanning fluorescent detector has been developed for plastic microchannel isoelectric focusing (mIEF) analysis. The detector, comprised of a lamp and photomultiplier tube (PMT) on a moving stage, measured the ...
Rapid, upward buoyant filtration combustion waves driven by convection
(Elsevier Science B.V., Amsterdam, 2001-01)
A two-temperature model is employed to analyze upward buoyant filtration combustion (BFC) waves. We consider heterogeneous (solid/gas) combustion in a porous sample open to gas flow only at the top and the bottom. The ...
Black hole demographics from the M•[BH] − σ[sigma] relation
(Monthly Notices of the Royal Astronomical Society, 2001-01)
We analyze a sample of 32 galaxies for which a dynamical estimate of the mass of the hot stellar component, Mbulge, is available. For each of these galaxies, we calculate the mass of the central black hole, M•, using the ...
Extended tasks elicit complex eye movement patterns
(Association for Computing Machinery., 2000-11-06)
Visual perception is an inherently complex task, yet the bulk
of studies in the past were undertaken with subjects
performing relatively simple tasks under reduced laboratory
conditions. In the research reported here, ...
Testing the photoionization models of powerful radio galaxies: Mixed line-emitting media in 3C 321
(Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 2000-10)
The photoionization models for the narrow emission line regions of powerful radio galaxies have yet to be tested in depth. To this end, we present high-quality long-slit spectroscopy of the powerful double-nucleus radio ...
Chaotic transitions and low-frequency fluctuations in semiconductor lasers with optical feedback
(Elsevier Science B.V., 2000-10)
This paper examines the dynamical origin of low-frequency fluctuations (LFFs) in semiconductor lasers subject to time-delayed optical feedback. In particular, we study chaotic transitions leading to the onset of LFFs by ...
Internship accessibility issues for deaf and hard-of-hearing applications: No cause for complacency.
(American Psychological Association, 2000-10)
What are the experiences of Deaf and hard-of-hearing students in applying for predoctoral internships in professional psychology? Are internship programs aware of accessibility issues in regard to these applicants? Federal ...
Bifurcation to mixed external cavity mode solutions for semiconductor lasers subject to optical feedback
(Elsevier Science B.V., 2000-09-15)
The Lang and Kobayashi equations modeling a semiconductor laser subject to optical feedback admit time-periodic solutions which are combinations of two distinct external cavity modes. We construct these solutions analytically ...
Dynamic modeling of long-term sedimentation in the Yadkin River basin
(Elsevier: Advances in Water Resources, 2000-07)
Modeling of sediment transport in relation to changing land-surface conditions against a background of considerable natural variability is a challenging area in hydrology. Bayesian dynamic linear models (DLMs) however, ...
