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, ...
Heterodyne detection for Fiber Bragg Grating sensors
(Elsveier - Optics & Laser Technology, 2000-07)
In this paper, we present a Fiber-Bragg-Grating-based temperature sensor. The technique employs heterodyne detection using two Fiber Bragg Gratings. One of the gratings is used as a reference (local oscillator) and the ...
The response of the 'new consumer' to promotion in the transition economies of the former soviet bloc
(Elsevier Science B.V., 2000-07)
Before the collapse of communism, promotion in the former Soviet Bloc functioned more as either propaganda or generic information rather than what marketers would call marketing. Today's "new consumer" in these transition ...
The large scale distribution of warm ionized gas around nearby radio galaxies with jet-cloud interactions
(Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 2000-06)
Deep, narrow-band Halpha observations taken with the TAURUS Tunable Filter (TTF) on the 4.2m WHT telescope are presented for two nearby radio galaxies with strong jet-cloud interactions. Although the brightest emission ...
High-resolution radio observations of Seyfert galaxies in the extended 12-micron sample - I. The Observations
(Blackwell Publishing, 2000-05)
We present 8.4 GHz VLA A–configuration observations of 87 sources from the
mid–infrared–selected AGN sample of Rush et al. (1993). These 0.25 arcsec resolution
observations allow elongated radio structures tens of parsecs ...
