First-Year spectroscopy for the SDSS-II Supernova Survey
(American Astronomical Society - The Astronomical Journal, 2008-05)
This paper presents spectroscopy of supernovae discovered in the first season
of the Sloan Digital Sky Survey-II Supernova Survey. This program searches
for and measures multi-band light curves of supernovae in the ...
The rotating wind of the quasar PG 1700+518
(Nature Publishing Group, 2008-02-27)
It is now widely accepted that most galaxies undergo an active phase, during which a
central super-massive black hole generates vast radiant luminosities through the
gravitational accretion of gas1,2. Winds launched from ...
The Sloan Digital Sky Survey-II Supernova Survey: search Algorithm and follow-up observations
(American Astronomical Society - The Astronomical Journal, 2008-01)
The Sloan Digital Sky Survey-II Supernova Survey has identified a large number
of new transient sources in a 300 deg2 region along the celestial equator during
its first two seasons of a three-season campaign. Multi-band ...
Towards a spectral technique for determining material geometry around evolved stars: Application to HD 179821
(Wiley-Blackwell, 2008)
HD 179821 is an evolved star of unknown progenitor mass range (either post-
Asymptotic Giant Branch or post-Red Supergiant) exhibiting a double peaked spectral
energy distribution (SED) with a sharp rise from ∼ 8−20 μm. ...
The Sloan Digital Sky Survey-II Supernova Survey: technical summary
(American Astronomical Society - The Astronomical Journal, 2008-01)
The Sloan Digital Sky Survey-II (SDSS-II) has embarked on a multi-year project to
identify and measure light curves for intermediate-redshift (0.05 < z < 0.35) Type Ia supernovae
(SNe Ia) using repeated five-band (ugriz) ...
Automotive transportation in China: Technology, policy, market dynamics, and sustainability
(Taylor and Francis. The definitive copy can be found at http://www.tandf.co.uk/journals/default.asp., 2008)
Over the past two decades, China has become a global economic force. However this economic growth has led to significant increases in carbon-intense energy consumption, with potentially disastrous impacts on the global ...
Modeling technology diffusion of complementary goods: The Case of hydrogen vehicles and refueling infrastructure
(Elsevier, 2008)
Hydrogen has emerged as a possible transportation fuel for addressing long-term, sustainable energy supply, security, and
environmental problems. Yet, there are a number of barriers that need to be overcome if hydrogen ...
Benefits of Sign Language Interpreting and Text Alternatives for Deaf Students’ Classroom Learning
(Oxford Journals, 2008)
Four experiments examined the utility of real-time text in
supporting deaf students’ learning from lectures in postsecondary
(Experiments 1 and 2) and secondary classrooms
(Experiments 3 and 4). Experiment 1 compared ...
Streak detection in mottled and noisy images
(SPIE, 2007-12-06)
We describe a method for automatically detecting
streaks in printed images using adaptive window-based image projections
and mutual information. The proposed approach accepts a
scanned image enclosing the defect and ...
Exploring the variable sky with the Sloan Digital Sky Survey
(American Astronomical Society - The Astronomical Journal, 2007-12)
We quantify the variability of faint unresolved optical sources using a catalog
based on multiple SDSS imaging observations. The catalog covers SDSS Stripe
82, which lies along the celestial equator in the Southern ...
