Acoustic scattering by discontinuities in waveguides
The scattering of acoustic waves by boundary discontinuities in waveguides is analyzed using the Method of Matched Asymptotic Expansions (MAE). Existing theories are accurate only for very low frequencies. In contrast, the theory developed in this thesis is valid over the entire range of …

Discontinuities, Balance Laws, and Material Momentum
… study of a class of problems involving discontinuities, also referred to as shocks, propagating through one dimensional flexible objects such as strings and rods. The study entails interrogation of the classical balance laws of momentum, angular momentum, and energy across propagating …

Failure Modes of Asperities in Rock Discontinuities
This work has proven the significant role of tensile failure in fracture process of asperities under direct shear loading. The result of this work can be combined with future research to develop a more meaningful relationship between the peak shear strength of the rock joints and the applied normal …

Orbit discontinuities and topological models for Borel semiflows
… examine the prevalence and structure of orbit discontinuities for arbitrary Borel semiflows. In particular we show that points have only countably many orbit discontinuities and that the set of orbit discontinuities has measure zero with respect to any measure preserved by the semiflow. …

Internal Photoemission and Energy Band Discontinuities at Semiconductor Heterojunctions
… been developed to measure the conduction band discontinuities ($\Delta$E$\sb{\rm c})$ at certain semiconductor heterojunctions. The technique involves measuring the spectral response of specially designed p$\sp{+}$N$\sp{-}$ heterojunction photodiodes. Internal photoemission from the valence …

Reconciling Discontinuities and Disruptions: The Construction of an Integrated Typology
<p>Radical innovations are often characterized by a rapid shift from one dominant design to another. The theories of discontinuous and disruptive innovation present two important and independent explanations for why these shifts occur. This research tests the usefulness of combining these two …

Receiver function imaging of mantle transition zone discontinuities beneath Alaska
… the subducted slab. The Mantle transition zone discontinuities of the 410km and the 660 km provide independent constraints on the depth extent of the subducted slabs. We conducted a receiver function study to map the topography of the 410 km and the 660 km discontinuities beneath Alaska and its …

Imaging Resolution of the 410-km and 660-km Discontinuities
The structure of seismic discontinuities at depths of about 410 km and 660 km provides important constraints on mantle convection as the associated mineral phase transformations in the transition zone are sensitive to thermal perturbations. Teleseismic P-to-S receiver functions have been widely …

Active control of acoustic radiation due to discontinuities on thin beams
… the active control of acoustic radiation due to discontinuities on thin beams. One experiment investigated the radiation from a clamped end condition and the other investigated the radiation from a blocking mass. The beams were excited by subsonic flexural traveling waves which "scattered" (or …

Effects of web reinforcement discontinuities on the seismic response of structural walls
<p>Field evidence was interpreted to suggest that discontinuities in the longitudinal web reinforcement caused severe damage in structural walls during strong ground motion. To test this hypothesis, six small-scale reinforced concrete structural walls were tested under lateral displacement …

Discontinuities in the Icebox Formation (Ordovician), Williston Basin, North Dakota and Montana
… largely composed of shale. This work shows that discontinuities and coarser facies exist within the Icebox Formation and that they are traceable throughout the subsurface of North Dakota and eastern Montana. This work also illustrates possible sea-level changes during the deposition of the Icebox …

Adjoint-based optimization for hyperbolic balance laws in the presence of discontinuities
… that appear in hyperbolic balance laws: contact discontinuities and shocks. These two have very different characteristics in the forward problem and we will see that they require different treatments for the adjoint formulations as well. Specifically, shocks require additional information, in the …
