1.1 This guide covers the dispersion in liquids of metal powders and related compounds for subsequent use in particle size analysis instruments. This guide describes a general procedure for achieving and determining dispersion; it also lists procedures that are currently in general use for certai...

1.1 This test method, when used in conjunction with a test performed by Method D422 on a duplicate soil sample, provides an indication of the natural dispersive characteristics of clay soils (1).

1.2 This test method is applicable only to soils with a plasticity index gre...

In this paper, by change of integration path in complex spectrum domain and by defining input admittance as the ratio of complex radiated power to amplitude of square of voltage across the gap, new expressions of admittance (valid for all frequencies) of infinitely long cylindrical antenna with and ...

With appropriate geometry configuration, helicopter-borne rotating synthetic aperture radar (ROSAR) can break through the limitations of monostatic synthetic aperture radar (SAR) on forward-looking imaging. With this capability, ROSAR has extensive potential applications, such as self-navigation and...

This paper addresses the problem of four-dimensional angle and Doppler frequency estimation for bistatic multiple-input multiple-output (MIMO) radar with arbitrary arrays in spatial colored noise. A novel method for joint estimation of Doppler frequency, two-dimensional (2D) direction of departure a...
