—This letter presents a pulsed high-efficiency power amplifier with increased spectral purity obtained by supply modulation of the pulse envelope. The PA operates at 2.14 GHz with 78% efficiency at 6 W peak power, and with 66.4% average efficiency over a 14.7 s pulse with a 4.1 dB PAR shaped by a 90% efficient resonant-pulse envelope supply modulator.

Current approaches to Information Extraction (IE) are capable of extracting large amounts of facts with associated probabilities. Because no current IE system is perfect, complementary and conflicting facts are obtained when different systems are run over the same data. Knowledge Fusion (KF) is the problem of ag-gregating facts from different extractors.(More)
