Neighborhood Pattern Recognition From Mailing Information: Links With Satellite Imagery, Victor Mesev

Online Journal of Space Communication

The notorious difficulties of sensing urban areas remotely have traditionally limited accuracy and thematic detail to coarse generalizations. With the advent of very high spatial resolution satellite imagery comes the opportunity to generate much finer scale inventories of the geography of cities. However, urban reconstruction from imagery is still limited to the classification of physical land covers; and land use still, on the whole, is inferred from the spectral composition of land covers. What is needed to improve urban image pattern recognition and classification accuracy is for GIS to keep pace with the demand for finer spatial resolution ancillary data …

Introduction To Hyperspectral Image Analysis, Peg Shippert

Online Journal of Space Communication

The most significant recent breakthrough in remote sensing has been the development of hyperspectral sensors and software to analyze the resulting image data. Fifteen years ago only spectral remote sensing experts had access to hyperspectral images or software tools to take advantage of such images. Over the past decade hyperspectral image analysis has matured into one of the most powerful and fastest growing technologies in the field of remote sensing.

The "hyper" in hyperspectral means "over" as in "too many" and refers to the large number of measured wavelength bands. Hyperspectral images are spectrally overdetermined, which means that they provide …

Spectrometry And Hyperspectral Remote Sensing Of Urban Road Infrastructure, Martin Herold, Margaret E. Gardner, Val Noronha, Dar A. Roberts

Online Journal of Space Communication

Based on a comprehensive regional spectral library from spectrometer ground measurements and high-resolution hyperspectral AVIRIS data, this research investigates generic spectral characteristics, and related mapping capabilities and limitations for extracting roads of various types, delineating road centerlines, and surveying pavement quality within the urban environment. The methods are generally successful in identifying roads and road pavement types, but inaccuracies arise from spectral similarities between asphalt surfaces and specific roofing materials. Findings indicate that it is possible to spectrally characterize and estimate age of pavement and a few specific asphalt surface quality parameters (e.g. raveling). Finally, this research argues that the …

Thermochemistry Of Combustion In Polyvinyl Alcohol + Hydroxylammonium Nitrate, James K. Baird, Robert A. Frederick Jr.

PRC-Affiliated Research

A mixture of polyvinyl alcohol (PVA) and hydroxylammoniun nitrate (HAN) forms a gummy solid known as a plastisol, which is ionically conducting. When an electrostatic potential of 200 V DC is applied across the plastisol, it ignites. Combustion ceases upon removal of the applied voltage. The products of PVA + HAN combustion are known to include the molecular gases carbon monoxide, carbon dioxide, water, nitrogen, and hydrogen. When the electric field within the plastisol is spatially uniform, combustion occurs preferentially at the anode. The fact that HAN is an ionic conductor suggests that the mechanism of combustion is electrolytic in …

Highly Branched Polymers Based On Poly(Amino Acid)S For Biomedical Application, Marisa Thompson, Carmen Scholz

PRC-Affiliated Research

Polymers consisting of amino acid building blocks continue to receive consideration for biomedical applications. Since poly(amino acid)s are built from natural amino acids, the same building blocks proteins are made of, they are biocompatible, biodegradable and their degradation products are metabolizable. Some amino acids display a unique asymmetrical AB2 structure, which facilitates their ability to form branched structures. This review compares the three forms of highly branched polymeric structures: structurally highly organized dendrimers, dendrigrafts and the less organized, but readily synthesizable hyperbranched polymers. Their syntheses are reviewed and compared, methods of synthesis modulations are considered and variations on their traditional …
