Microscopy studies of low energy-high flux nitrided ODS FeAl Grade 3 intermetallic alloy reveal a surface containing a random distribution of protrusions anchored by yttria particles. The cross section analyses show the ...
-
A method is presented to evaluate the detection performance of real-time QRS detection algorithms to propose a strategy for the adaptive selection of QRS detectors, under variable signal contexts. Signal contexts are def...
-
Tropical sandy soils (or upper sandy horizons of tropical soils) have diverse physical and chemical constraints: poor structural stability (making soils sensitive to crusting, and compaction), poor nutrient holding capac...
