We extend previously developed oscilloscope sampler models to include realistic circuit characteristics and use these models to investigate the nose-to-nose
Ultra-small-angle X-ray scattering by dislocations in single-crystal aluminum has been observed in situ as a function of plastic deformation. The scattering is
I address the issue of the definition and measurement of noise figure and parameters to characterize multiport devices, particularly differential amplifiers. A
We have studied the effects of interface morphology on the dynamics of dendritic growth. The Ivantsov solution for an isothermal paraboloid of revolution
Static gravimetric and static volumetric gas flow standards are both affected by uncertainty components related to the measurement of the change of mass of gas
We examine the stability of polarization switching in polyscrystalline ferroelectric/ferroelastic materials subject to continuous electromechanical loading. In
