Unsupervised unmixing of hyperspectral imagery using the constrained positive matrix factorization
In hyperspectral imaging, hundreds of images are taken at narrow and contiguous spectral bands providing us with high spectral resolution spectral signatures that can be used to discriminate between objects. In many ...
Coastal habitat connectivity of reef fishes from southwestern Puerto Rico
In the western Atlantic, despite increasing concerns about designing and implementing an integrated approach in coastal conservation and management, the ecological relationships (i.e., habitat connectivity) for reef ...
Improved binary and ternary nanostructured photocatalysts for gas phase detoxification of toluene
Photocatalysis using nanocrystalline materials with enhanced catalytic properties under ultraviolet (UV) or visible light has the potential for becoming one of the leading processes for the abatement of environmental ...
On some algorithms for reverse engineering certain finite dynamical systems
There are two general problems related to finite dynamical systems (FDS): the analysis and the synthesis (also known as the reverse engineering) problems. In the former, we are interested in uncovering the sequential ...
Dynamic properties and seismic response of the cable structures and towers of the Arecibo Observatory
This investigation was requested by the staff of the Arecibo Observatory to determine whether the towers and cables that support the suspended platform are capable of resisting a maximum-credible earthquake in the elastic ...
In situ diffraction studies of Ni nanostructure growth using microporous materials as supports
Our objective is to study the growth mechanism of Ni nanostructures supported in microporous materials using X-ray diffraction. Since only the surface atoms of a catalyst are active, our aim is to find the optimum synthesis ...
