Evaluating the African arid corridor hypothesis: A meta‐analysis including the phylogenetic and biogeographical history of Sesamothamnus

American Journal of Botany, EarlyView.
Abstract Premise We examined the African arid corridor (AAC) disjunction pattern of vascular plants between northeastern and southwestern Africa in the context of geological and climatic events since the late Miocene. We developed a phylogenetic and biogeographical framework for the arid‐adapted genus Sesamothamnus (Pedaliaceae), a classic example of ...

Development and Application of a Programmable Partial Discharge Calibrator

IEEE Transactions on Instrumentation and Measurement, 2009
A programmable partial discharge (PD) calibrator composed of an arbitrary waveform generator that is series connected to a capacitor is described. The voltage waveform supplied by the generator is software controlled. The characteristics and capabilities of the calibrator are presented, and the procedures used for its characterization are discussed ...

Study on the calibration of partial discharge calibrator

2008 Conference on Precision Electromagnetic Measurements Digest, 2008
The calibration of apparent charge, which can be traced to AC voltage and capacitance, for partial discharge(PD) calibrator is discussed. The methods of fast sampling measurement of peak-to-peak amplitude for step voltage by digital multimeter and the arithmetic in the automatic measurement of apparent charge by digital oscilloscope are focused on ...

Application of a Programmable Partial Discharge Calibrator

Applied Mechanics and Materials, 2014
This paper presents the application of a programmable partial discharge calibrator, which used to test the performance of four partial discharge measuring systems by injecting a program controlled known charge sequence into the device under test. Performance of linearity, response to opposite polarity pulses, pulse resolution time and response to ...
