Collection and characterization of maize and upland rice populations cropped by resource-poor farmers in the uplands of Panama's Azuero region
Download2009
Spaner, Dean, Dreisigacker, Susanne, Love, Brian
The conservation of crop genetic resources is an international priority and requires the continued collection and characterization of farmer varieties. We collected and characterized maize and upland rice populations cropped by farmers in Panama's Azuero region. The objective of our study was to...

Interdisciplinary communication, and thus the rate of progress in scholarly understanding, would be greatly enhanced if scholars had access to a universal classification of documents or ideas not grounded in particular disciplines or cultures. Such a classification is feasible if complex concepts...

Content-Based Image Retrieval Using Binary Signatures
2000
Nascimento, Mario, Chitkara, Vishal, Mastaller, Curt
Technical report TR00-18. Significant research has focused on determining efficient methodologies for retrieving images in large image databases. In this paper, we propose two variations of a new image abstraction technique based on signature bit-strings and an appropriate similarity metric. The...

Data analysis for the classification of gas-liquid and liquid-solid (slurry) flows using digital signal processing
DownloadSpring 2013
The Canadian oil sand industry operates three phase gas-liquid-solid hydrotransport pipelines to transport oil sand ore from mines to processing facilities. This hydrotransport process is critical to downstream separation activities, given the conditioning steps that occur within it: (i) lump...
