High-resolution direct numerical simulation data for three-dimensional Navier-Stokes turbulence in a periodic box are used to study the scaling behavior of low-order velocity structure functions with positive and negative powers. Similar to high-order statistics, the low-order relative scaling exponents exhibit unambiguous departures from the Kolmogorov(More)
We have reported previously [1] a low-swing latch (LSL) with superior performance-power tradeoff compared to the conventional pass-gate master-slave latch. In this paper, hardware results are presented for the proposed LSL with pulsed clock waveforms. The motivation is to combine low-voltage swing with pulsed signals to further reduce overall system power(More)
Properties of velocity circulation in three-dimensional turbulence are studied using data from highresolution direct numerical simulation of Navier-Stokes equations. The probability density function (PDF) of the circulation depends on the area of the closed contour for which circulation is calculated, but not on the shape of the contour. For contours lying(More)
