SHARPENDING OF THE VNIR AND SWIR BANDS OF THE WIDE BAND SPECTRAL IMAGER ONBOARD TIANGONG-II IMAGERY USING THE SELECTED BANDS
Sharpening band selection Tiangong-II VNIR and SWIR bands Wide band spectral imager
2018/5/15
The Tiangong-II space lab was launched at the Jiuquan Satellite Launch Center of China on September 15, 2016. The Wide Band Spectral Imager (WBSI) onboard the Tiangong-II has 14 visible and near-infra...
Stark Effect Spectroscopy of the Heme Charge Transfer Bands of Deoxymyoglobin
materials science electronic structure oxygen compounds myoglobin charge transport stark effect absorption spectra spectroscopy heme protoporphyrins
2016/5/23
We report the Stark spectra of the Soret, Q, and charge-transfer bands of deoxymyoglobin. The data show that band III has charge-transfer character but that the magnitude of the charge displacement is...
Computational modeling of deformation bands in granular media. I. Geological and mathematical framework
Deformation bands Granular media
2015/7/1
Failure of granular media under natural and laboratory loading conditions involves a variety of micromechanical processes producing several geometrically, kinematically, and texturally distinct types ...

Deformation bands Granular media
2015/7/1
Development of accurate mathematical models of geomaterial behavior requires a more fundamental understanding of the localization phenomena; in particular, the important factors responsible for the in...
Improvements on Near Real Time Detection of Volcanic Ash Emissions for Emergency Monitoring with Limited Satellite Bands
Volcanic ash disperion monitoring satellite dispersion model
2015/8/18
Quantifying volcanic ash emissions syneruptively is an important task for the global aviation community. However, due to the near real time nature of volcano monitoring, many parameters important for ...

2014/5/13
While setting out to fabricate new springs to support a cephalopod-inspired imaging project, a group of Harvard researchers stumbled upon a surprising discovery: the hemihelix, a shape rarely seen in ...
University of Queensland researchers have found physical evidence in Great Barrier Reef corals of a little-known, long-term climate pattern in the Pacific Ocean.
Adaptive Sensing of Congested Spectrum Bands
Adaptive agility sparsity spectrum sensing wideband
2012/6/27
Cognitive radios process their sensed information collectively in order to opportunistically identify and access under-utilized spectrum segments (spectrum holes). Due to the transient and rapidly-var...
VUV Fourier-transform absorption study of the Lyman and Werner bands in D2
VUV Fourier-transform absorption Lyman and Werner bands D2 Atomic Physics
2012/4/24
An extensive survey of the D2 absorption spectrum has been performed with the high-resolution VUV Fourier-transform spectrometer of the DESIRS beamline at the SOLEIL synchrotron. The frequency range o...
Rotational Bands and Electromagnetic Transitions of some even-even Neodymium Nuclei in J-Projected Hartree-Fock Model
J-Projected Hartree-Fock Model Nuclei Electromagnetic Transitions
2011/7/20
Rotational structures of even-even $^{148-160}$Nd nuclei are studied with the self-consistent deformed Hartree-Fock (HF) and angular momentum (J) projection model. Spectra of ground band, recently obs...
Excitation of the aromatic infrared emission bands: Chemical energy in hydrogenated amorphous carbon particles?
Excitation aromatic infrared emission bands: Chemical energy
2011/10/11
We outline a model for the heating of hydrogenated amorphous (HAC) dust via the release of stored chemical energy and show that this energy (~12 kJ/mole) is sufficient to heat dust grains of classical...

We describe possible conditions for stationnary inhomogeneous flow behaviour (sheared and
blocked bands) in a continuous mechanical model of a soft visco-elasto-plastic material such as
a foam or a ...
