ABSTRACT
A systematic method is developed for construction of microstructures of poly- and nanocrystalline materials for various numerical modeling and simulations. The automatic method uses as input the distribution functions of microstructure quantities such as the grain size or texture and, through a sequence of minimization procedures, obtains the desired microstructures. The digital samples generated using this method agree well with experimental samples in their topological, structural, and statistical properties. The application and impact of this method on atomistic and continuum simulation and modeling are discussed. © 2002 American Institute of Physics.

    A new approach, called adaptive Q control, for tapping-mode atomic force microscopy (AFM) is introduced and implemented on a homemade AFM setup utilizing a laser Doppler vibrometer and a piezoactuated bimorph probe. In standard Q control, the effective Q factor of the scanning probe is adjusted...

    Coulomb explosion of spherical ion clusters is studied, which are composed of homogeneous two-species (light and heavy) ions. A simple analytical model is developed to describe the explosion performance in terms of two dimensionless parameters, the charge-over-mass ratio, and the charge density...

    We describe how a lock-in amplifier can be used in a feedback loop to lock the frequency of a laser to an atomic transition in [sup 85] Rb. A simple physical explanation is presented to describe the shape of the feedback signal generated by the "lock in" and the dependence of this signal on the...

    This chapter is an attempt to attain a new and profound model of the nature’s structure using a vortex-ring-fractal theory (VRFT). Scientists have been trying to explain some phenomena in Nature that have not been explained so far. The aim of this paper is the vortex-ring-fractal modeling...

    An analytical model for estimating basic characteristics of short (without a positive column) glow discharges is suggested that allows for electron generation both in the cathode sheath and by nonlocal ionization in the plasma negative glow. The model is based on a previously developed approach...

    Each charged particle loses its energy while passing through a matter. These charged particles have electrons. Electrons lose their energy as a result of the interaction with the matter in four ways: 1. Bremsstrahlung, 2. electron-positron pair annihilation, 3. inelastic collision of electrons...
