Automated grading of colon biopsy images across all magnifications is challenging because tailored segmentation and dependent features on each magnification. This work presents a novel approach robust magnification-independent cancer framework to distinguish into four classes: normal, well, moderate, poor. The contribution this research develop magnification invariant hybrid feature set compris...
555 Abstract—The Wildland Fire Assessment System (WFAS) is a component of the U.S. Department of Agriculture, Forest Service Decision Support Systems (DSS) that support fire potential modeling. Fire potential models for Mississippi and for Eastern fire environments have been developed as part of a National Aeronautic and Space Agency-funded study aimed at demonstrating the utility of NASA asset...
In this paper, multi-frequency synthetic aperture radar (SAR) data at L- and C-bands (ALOS PALSAR Envisat/ASAR) were used to estimate forest biomass in Tuscany, Central Italy. The ground measurements of woody volume (WV, m3/ha), which can be considered as a proxy biomass, retrieved from the Italian National Forest Inventory (NFI). After preliminary investigation assess sensitivity backscatter C...
Abstract How do learners make sense of what they are learning? In this article, I present a new framework sense-making based on research investigating the benefits and boundaries generative learning activities (GLAs). The distinguishes among three primary modes—explaining, visualizing, enacting—that each serve unique complementary cognitive functions. Specifically, assumes mentally organize sim...
The Seal Nunataks ice shelf (SNIS, ∼743 km in 2013) is an unofficial name for a remnant area between the former Larsen A and Larsen B ice shelves off the northeastern Antarctic Peninsula. Analyses using Landsat 7 ETM+ and Terra ASTER images from 2001 to 13 and ICESat altimetry from 2003 to 09 show it has retreated and thinned following the Larsen A (1995) and Larsen B (2002) disintegrations. De...
