The growth rates of Si(001) and Ge(001) by gas-source molecular-beam epitaxy (GS-MBE) from $\rm Si\sb2H\sb6$ and $\rm Ge\sb2H\sb6$ as a function of T$\sb{\rm s}$ are well described by a model based upon dissociative $\rm ... application/pdf PDF (6MB) • (1998) Next, we consider the design of signal-adapted subband filter banks to be incorporated into our wavelet video coder, for the purpose of further improving compression efficiency, and for protection against channel errors ... application/pdf PDF (7MB) • (1988) Considered in this thesis is the class of time-inhomogeneous Markov chains whose transition probabilities are proportional to nonnegative powers of a small, time-varying parameter. A new notion of order of recurrence is ... application/pdf PDF (2MB) • (1991) This thesis describes techniques for bandwidth enhancement for low-profile antennas. The first method involves the use of coupled resonators. In particular, two cavity-backed slot antennas are coupled through an aperture ... application/pdf PDF (4MB) • (1991) Robust large-angle spacecraft pointing and tracking by Variable Structure Control (VSC) are developed. The control of multiaxial attitude dynamics is a highly nonlinear problem, which can be resolved by exact feedback ... application/pdf PDF (3MB) • (2003) Next, the problem of covering an incompletely-specified negative function by a completely-specified negative function efficiently is investigated. This problem arises during the synthesis of MOS networks. A necessary step ... application/pdf PDF (5MB) • (1991) This thesis describes the use of the eigenvalue method for computing the modes of cavity resonators. A matrix formulation of the integral equation describing the modes of a resonator is a powerful and flexible method of ... application/pdf PDF (2MB) • (1970) application/pdf PDF (3MB) • (1958) application/pdf PDF (4MB) • (1993) In this thesis, a behavioral-level testability analysis approach is presented. This approach is based on analyzing the circuit behavioral description (similar to a C program) to estimate its testability by identifying ... application/pdf PDF (4MB) • (1977) application/pdf PDF (4MB) • (1995) The properties of a silicon adatom on Si(001) surface and around three single-layer steps, namely type A (S$\rm\sb A$), bonded type B (S$\rm\sb B$) and nonbonded type B (S$\rm\sb{B\sp\prime}\$), on Si(001) have been studied, ...
