The formation and initial stage of the motion of several rapid, impulsive coronal mass ejections of the “halo” type (HCME) associated with flares of M and X class, but unassociated with the eruption of solar filaments, was studied using GOES-12/SXI, SOHO/EIT, and SDO/AIA data.

IEEE Photonics Technology Letters, 2012
We demonstrate the novel operation of a Si/Ge-based avalanche photodiode (APD) for the direct generation of ultra-wideband (UWB) frequency comb lines for impulse radio (IR) wireless communication. By applying a dc bias (Vbias) over the breakdown voltage (Vbr) of the APD, the device can exhibit a significant resonant frequency without any optical signal

Streak Camera Observations of Partial Discharg Polyethylene under Fast Impulse Voltage Stress
1991 Annual Report. Conference on Electrical Insulation and Dielectric Phenomena,, 2005Samples of polyethylene with electrical trees at the tip of a needle radius/9 mm gap) molded into the material were subjected to voltage impulses of between 50 and 85 kV (20 ns/2 /spl mu/s). The light emitted from the partial discharges was recorded with a streak camera. Light was emitted for less than 20 ns for a positive impulse of 70 kV.

IEEE Transactions on Instrumentation and Measurement, 2013
This paper presents the design and calibration of seven new Rogowski coils, namely, three air-cored coaxial-cable wound coils (RC1-RC3), one ferrite-cored varnished-wire wound coil (RC4), and three air-cored varnished-wire-wound coils (RC5- RC7). All coils are wound in a single layer and operated in the self-integrating mode, especially RC1-RC4.

New Side-Looking Rogowski Coil Sensor for Measuring Large-Magnitude Fast Impulse Currents
Sensing and Imaging, 2014This paper presents a new design of a side-looking “flat spiral” self-integrating Rogowski coil that is wound by twin coaxial cable with individual sheath. The coil is tested with different impulse current waveforms up to 7 kA peak value to improve its performance.

A Robophysical Mantis Shrimp Model to Study Ultra-Fast "Impulsive" Biological and Synthetic Systems
2022Breakthroughs in multi-scale, multi-material rapid fabrication and new materials have led to the increased use of robots as tools to understand biological systems in a growing field known as robophysics. Here, a mesoscale mantis shrimp robot, manufactured using laminate origami-inspired techniques called "Pop-up MEMS", is used to characterize the ...
