Satellite derived rainfall over tropical Africa : its pattern variability and calibration
The major spatial and temporal structure of rainfall and zonal wind at seasonal and intra-seasonal time-scales over tropical Africa are identified by principal component analysis. Pentad CMAP rainfall and NCEP 700hPa zonal wind for the period 1980-2000 were used. Wavelet analysis is used to filter …

Antenna element pattern reconfigurability in adaptive arrays
… going beyond utilizing ideal, traditional, fixed-pattern antenna element patterns to include element patterns more relevant to pattern reconfigurable antennas. The results demonstrate that a practical pattern reconfigurable element can produce results comparable to that of the ideal element and …

How does context variability affect representational pattern similarity to support subsequent item memory?
… magnetic resonance imaging (fMRI) data when the pattern across its smallest units (voxels, often 3mm3 sections of the brain) is measured. Many prior studies have measured these voxel patterns in response to stimuli as if they are a spontaneous brain function, regardless of cognitive factors. …
