INFORMATION CONTENT ANALYSIS FROM VERY HIGH RESOLUTION OPTICAL SPACE IMAGERY FOR UPDATING SPATIAL DATABASE
Information Content Topographing Mapping GIS Remote Sensing VHR Images
2018/11/9
High resolution satellite images started with IKONOS imagery. After the launch of the very high resolution IKONOS in the 1990s, a new generation of commercial Earth-imaging satellites have pioneered a...

JILA’s Superradiant Laser May One Day Boost Atomic Clocks and ‘Rulers’ for Space
JILA Superradiant Laser Atomic Clocks Rulers Space
2016/11/4
JILA physicists have demonstrated a novel laser design based on synchronized emissions of light from the same type of atoms used in advanced atomic clocks. The laser could be stable enough to improve ...
A signal-strength model for gravity-field spectrum components in a local space
Earth's Gravitational Potential Local Area Spectrum Structure Spherical Cap Harmonic Analysi
2015/8/26
In the Earth gravity-field model, potential coefficients are projections of the Earth gravitational potential on the corresponding spherical harmonics by degree and order. These coefficients reflect t...
Bright pulses of light could make space veggies more nutritious, says CU-Boulder study（图）
light nutritious Bright pulses
2014/3/20
Exposing leafy vegetables grown during spaceflight to a few bright pulses of light daily could increase the amount of eye-protecting nutrients produced by the plants, according to a new study by resea...
Experimental phase-space-based optical amplification of scar modes
Experimental phase-space-based optical amplification scar modes Optics
2012/4/20
Waves billiard which are chaotic in the geometrical limit are known to support non-generic spatially localized modes called scar modes. The interaction of the scar modes with gain has been recently in...
Polarization-dependent transformation of a paraxial beam upon reflection and refraction: a real-space approach
Polarization-dependent transformation paraxial beam real-space approach reflection refraction
2011/8/3
Abstract: We analyze the paraxial beam transformation upon reflection and refraction at a plane boundary. In contrast to the usual approach dealing with the beam angular spectrum, we apply the continu...
We construct a class of coherent spin-network states that capture proprieties of curved space-times of the Friedmann-Lamaˆıtre-Robertson-Walker type on which they are peaked.
Static isolated horizons: SU(2) invariant phase space, quantization, and black hole entropy
Static isolated horizons invariant phase space quantization black hole entropy
2010/12/20
We study the classical field theoretical formulation of static generic isolated horizons in a man-ifestly SU(2) invariant formulation. We show that the usual classical description requires revision in...
Non-Parametric Tests of Structure for High Angular Resolution Diffusion Imaging in Q-Space
High Angular Resolution Imaging in Q-Space
2010/11/18
High angular resolution diffusion imaging data is the observed characteristic function for the local diffusion of water molecules in tissue. This data is used to infer structural information in brain...
Internal Space-time Symmetries of Particles derivable from Periodic Systems in Optics
Internal Space-time Symmetries Particles derivable Periodic Systems in Optics
2010/10/27
While modern optics is largely a physics of harmonic oscillators and two-by-two matrices, it is possible to learn about some hidden properties of the two-by-two matrix from optical systems. Since two-...
