The robustness of discrete-time systems in the presence of norm-bounded linear time-varying and/or nonlinear perturbations is addressed. A general framework for dealing with stability as well as performance robustness of ...

Magnetic Resonance (MR) imaging is a 3-D, multi-slice, radiological technique that acquires multiple intensities corresponding to each voxel. The transverse relaxation time, T$\sb1$, and the axial relaxation time, T$\sb2$, ...

Time series are often modeled as filtered versions of white noise, the filter being linear. We study non-Gaussian processes by modeling them similarly, but allowing the possibility of the filter being non-linear. These ...

A comprehensive theory of conduction in polycrystalline silicon is presented. The present approach fundamentally differs from previous theories in its treatment of the grain boundary. This theory regards the grain boundary ...

The task of stabilizing communication networks sharing a spread spectrum channel is addressed. A slotted system is considered and the stabilization is achieved by controlling the number of packets that are transmitted in ...

This thesis develops several new algorithms for computing the discrete Fourier transform (DFT). The work describes algorithms for which a set of constraints on the input or the output allow the DFT to be computed more ...

Wavelet transforms provide a new technique for time-scale analysis of non-stationary signals. Wavelet analysis uses orthonormal bases in which computations can be done efficiently with multirate systems known as filter ...

The rare gas alkali ionic excimers (RgA)$\sp+$& are investigated as possible VUV laser sources. The detection of emission from (XeRb)$\sp+$ at 165 nm using laser produced plasma soft x-ray excitation is reported. In addition ...

Knowing the number of sources in the acoustic field of a narrowband passive array can be very useful when determining the bearing of these sources relative to the array; many of the "high resolution" bearing estimation ...

This thesis describes algorithms that fuse the data from a single video camera and a laser rangefinder. By merging information from these sensors, the algorithms build a digital map of the local environment for a robot to ...
