A time revolved spectroscopic study of the emission phases occurring throughout a nanosecond pulsed discharge in water is presented. Discharged are ignited in deionized water via a submerged pin-t-plane electrode configuration by application of 24kV pulses with a rise time of 4ns and a duration of 10ns. Optical emission spectroscopy of the plasma radiation is performed, revealing a very complex...

The behaviour of passive tracer particles in capillary Poiseuille flow is investigated with regard to the residence time in short axial sections of length z , in which z /a < Va/D, where a is the capillary radius, V is the mean velocity and D the coefficient of molecular diffusion. While methods exist for calculating moments of the crosssectionally averaged axial concentration distribution as a...

We discuss the rise of a liquid inside an angular capillary tube. It is shown that for a wetting liquid, the height of the rise is (as usually) inversely proportional to the length which characterizes the confinement. The exact laws deduced from energetic considerations are found to be in excellent agreement with the data. We then show how such tubes can be used to prevent bubbles from being tr...

Several pairs of observable properties of Gamma Ray Bursts (GRBs) are known to be correlated. Many such correlations are straightforward predictions of the ‘cannonball’ model of GRBs. We extend our previous discussions of the subject to a wealth of new data, and to correlations between ‘lag-time’, ‘variability’ and ‘minimum rise-time’, with other observables. Schaefer’s recent systematic analys...

In previous studies, we conducted several experiments, including identification tests for young and elderly listeners using /shi/–/chi/ (CV) and /ishi/–/ichi/ (VCV) continua. For the CV stimuli, confusion of /shi/ as /chi/ increased when the frication had a long rise time, and /chi/ was confused with /shi/ when the frication had a short rise time. This was true for the group with the following ...

Programmed current chronopotentiometry, specifically current reversal and current decrease, is applied to electrode reactions characterized by a chemical reaction coupled between two charge-transfer reactions, the ECE mechanism. The equations for the transition times are derived and solved. Current-reversal results on systems following the ECE mechanism, p-nitrosophenol, p-nitrophenol, and o-ni...

On-chip inductance effects can be used to improve the performance of high-speed integrated circuits. Specifically, inductance improves the signal slew rate (the rise time), virtually eliminates short-circuit power consumption and reduces the area of the active devices and repeaters inserted to optimize the performance of long interconnects. These positive effects suggest the development of desi...

Experiments are described in which a plasma compression opening switch is used in planar geometry to sharpen the output pulse of an explosive-driven magnetic flux compression generator. Included are data from tests where peak opening switch currents range from 5.7 to 9.3 MA. The switch is used to transfer current to a static low-inductance load (-10 nH) with an efficiency of 50% or better and a...
