1 Mathews, V. John; Dubow, JoelA stable adaptive Hammerstein filter employing partial orthogonalization of the input signalsAbstract This paper presents an algorithm that adapts the parameters of a Hammerstein system model. Hammerstein systems are nonlinear systems that contain a static nonlinearity cascaded with a linear system. In this work, the static nonlinearity is modeled using a polynomial system and the linear f...2002

6 Myers, Chris J.Automatic derivation of timing constraints by failure analyisAbstract. This work proposes a technique to automatically obtain timing constraints for a given timed circuit to operate correctly. A designated set of delay parameters of a circuit are first set to sufficiently large bounds, and verification runs followed by failure analysis are repeated. Each ver...2002
7 Miller, Jan D.Bench scale flotation of sedimentary phosphate rock with hydroxamic acid collectorsIt has been discovered that water insoluble alcoholic solutions of alkyl hydroxamic acids serve as selective collectors for the flotation of phosphate mineral resources. The effectiveness of the new collector chemistry has been demonstrated by the results from single stage bench scale flotation exp...flotation; insoluble collectors; hydroxamic acid; alcohol; phosphate rock; high solids conditioning; particle size2002
8 Riloff, Ellen M.Bootstrapping method for learning semantic lexicons using extraction pattern contextsThis paper describes a bootstrapping algorithm called Basilisk that learns high-quality semantic lexicons for multiple categories. Basilisk begins with an unannotated corpus and seed words for each semantic category, which are then bootstrapped to learn new words for each category.

11 Bedrov, Dmitro; Smith, Grant D.Comparison of self-assembly in lattice and off-lattice model amphiphile solutionsLattice Monte Carlo and off-lattice molecular dynamics simulations of h1t4 and h4t1 (head/tail) amphiphile solutions have been performed as a function of surfactant concentration and temperature. The lattice and off-lattice systems exhibit quite different self-assembly behavior at equivalent ther...Amphiphile solutions; Micellization; Surfactants2002
12 Miller, Jan D.Cone beam X-ray microtomography - a new facility for three-dimensional analysis of multiphase materialsAs the techniques and resolution for three-dimensional spatial analysis have advanced in the last decade, it is now possible to map in detail the micro structure of multiphase materials in three-dimensional digital space. In this regard, three-dimensional X-ray microtomography offers a unique imagin...Ccne beam X-ray microtomography; three-dimensional analysis; material characterization2002
13 Tiwari, AshutoshCopper diffusion characteristics in single-crystal and polycrystalline TaNWe have investigated the diffusivity of copper in single-crystal (NaCl-structured) and polycrystalline TaN thin films grown by pulsed-laser deposition. Polycrystalline TaN films were grown directly on Si(100), while single-crystal films were grown with TiN buffer layers. Both poly- and single-crysta...Diffusion barriers; Copper diffusion; Tantalum nitride2002
14 Balasubramonian, RajeevEnergy-efficient processor design using multiple clock domains with dynamic voltage and frequency scalingAs clock frequency increases and feature size decreases, clock distribution and wire delays present a growing challenge to the designers of singly-clocked, globally synchronous systems. We describe an alternative approach, which we call a Multiple Clock Domain (MCD) processor in which the chip is d...Multiple clock domains; Synchronization; Microarchitecture2002
15 Scarpulla, MichaelEnhanced nitrogen incorporation by pulsed laser annealing of GaNxAs1-x formed by N ion implantationWe demonstrate that pulsed laser annealing followed by rapid thermal annealing greatly enhances incorporation of substitutional N in N1-implanted GaAs. Films implanted to 1.8% N exhibit a fundamental band gap of 1.26 eV (a band gap reduction of 160 meV), corresponding to an N activation efficiency ...Highly mismatched alloys; Gallium arsenide2002

23 Tasdizen, Tolga; Whitaker, Ross T.Geometric surface smoothing via anisotropic diffusion of normalsThis paper introduces a method for smoothing complex, noisy surfaces, while preserving (and enhancing) sharp, geometric features. It has two main advantages over previous approaches to feature preserving surface smoothing. First is the use of level set surface models, which allows us to process ver...2002
