Scour and fill in ephemeral streams : technical report by Michael G Foley( Book )
1 edition published in 1975 in English and held by 12 WorldCat member libraries worldwide
In this report the classical concept that mean bed elevation over an entire stream reach is lowered by scour during flood-wave passage and is restored by deposition in the waning flood phase (mean-bed scour and fill) is challenged. The alternative that both scour and fill occur concurrently at different migrating loci within a reach (local scour and fill) is more consistent with published field data. The field and laboratory investigations reported suggest that mean-bed scour and fill in a uniform channel is minor compared to local scour and fill caused by bedform migration, and that maximum local scour and fill may occur on the waning flood in some instances

The steady-state response of multidegree-of-freedom systems with a spatially localized nonlinearity by Richard K Miller( )
2 editions published in 1976 in English and held by 8 WorldCat member libraries worldwide
This thesis is concerned with the dynamic response of a General multidegree-of-freedom linear system with a one dimensional nonlinear constraint attached between two points. The nonlinear constraint is assumed to consist of rate-independent conservative and hysteretic nonlinearities and may contain a viscous dissipation element. The dynamic equations for general spatial and temporal load distributions are derived for both continuous and discrete systems. The method of equivalent linearization is used to develop equations which govern the approximate steady-state response to generally distributed loads with harmonic time dependence. The qualitative response behavior of a class of undamped chainlike structures with a nonlinear terminal constraint is investigated. It is shown that the hardening or softening behavior of every resonance curve is similar and is determined by the properties of the constraint. Also examined are the number and location of resonance curves, the boundedness of the forced response, the loci of response extrema, and other characteristics of the response. Particular consideration is given to the dependence of the response characteristics on the properties of the linear system, the nonlinear constraint, and the load distribution. Numerical examples of the approximate steady-state response of three structural systems are presented. These examples illustrate the application of the formulation and qualitative theory. It is shown that disconnected response curves and response curves which cross are obtained for base excitation of a uniform shear beam with a cubic spring foundation. Disconnected response curves are also obtained for the steady-state response to a concentrated load of a chainlike structure with a hardening hysteretic constraint. The accuracy of the approximate response curves is investigated

Entrainment in fire plumes by E. E Zukoski( Book )
3 editions published between 1985 and 1988 in English and held by 5 WorldCat member libraries worldwide
This report contains a description of an ongoing study of gravity currents for conditions which match those we expect to find in unwanted fires in building. A review is made of the pertinent literature and a description is given of the flow regimes which can exist for ideal gravity currents when viscous effects, heat transfer, and mixing are ignored. The influence of boundary conditions fixed by the method used to withdraw the fluid displaced by the current is given. Algebraic equations for the thickness of the current and the velocity of the head are derived for these ideal flows. The influences of viscosity and mixing are briefly discussed and the status of salt water and gas modeling experiments is given

Scanning tunneling microscopy and digital image correlation in nanomechanics investigations by Ying Huang( )
2 editions published in 2001 in English and held by 3 WorldCat member libraries worldwide
"Probe microscopy (scanning tunneling microscopy and atomic force microscopy) and digital image correlation together serve as a potentially powerful tool for experimentally investigating the mechanical behaviors of materials at the sub-micron and nanometer scales. Based on the tunneling effect in quantum physics, the scanning tunneling microscope (STM) records surface topography quantitatively and can achieve angstrom resolution. The digital image correlation (DIC) extracts the displacements and gradients from the undeformed and deformed topographical images. In this work, a calibration has been performed on the existing STM built "in-house" and the coefficients used in the STM system were confirmed. Major improvements on several components of the system have been made, including constructing a new actuator probe to decouple its in-plane and out-of-plane movements, designing and implementing a new first-stage amplifier to reduce the noise output by a factor of 10 and modeling of the controller in the STM feedback loop. Further, systematic study of the digital image correlation has been conducted. In the simple case of one-dimensional correlation, key parameters involved are the subset size, variables in the displacement representation, frequency content of the signal and noise. The one-dimensional study was then extended to two dimensions. In addition to those key parameters identified in the one-dimensional study, the sampling rate poses substantial influence on the correlation accuracy. Low amplitude, high frequency noise still increases the correlation error significantly. Finally, a detailed analysis of noise originating from the atomic force microscope (AFM) reveals that white noise can generate an "artificial" displacement that can cloud the displacement calculation when correlation is performed on a deformed specimen. A possible improvement is proposed to compensate for the hysteresis of the AFM piezo actuator."

Singularity formation in three-dimensional vortex sheets by Gang Hu( )
2 editions published in 2001 in English and held by 3 WorldCat member libraries worldwide
"In this thesis, we investigate both theoretically and numerically the singularity formation and long time existence of three-dimensional vortex sheets. For the theoretical work, we divide it into two parts. In the first part, we study the early time singularity formation and the local form of the vortex sheet in the neighborhood of a singularity near the singularity time. We show that under a special set of coordinates, the three-dimensional vortex sheet can be viewed as a two-dimensional vortex sheet along certain space curves. As a result, the study of singularity formation of a three-dimensional vortex sheet can be related to that of the corresponding two-dimensional vortex sheet. And the singular behavior of these two problems is very similar. Moreover, by performing a transformation in the interface variables and deriving leading order asymptotic approximations for the evolution of these transformed variables, we show that the Kelvin-Helmholtz instability is a result of the coupling of two of these three variables to the leading order. This observation simplifies significantly our singularity analysis for three-dimensional vortex sheets and allows us to reveal clearly the nature of the curvature singularity in the three-dimensional vortex sheet equation. In the second part of our theoretical work, we prove the long time existence of the three-dimensional vortex sheet problem for analytic initial conditions near equilibrium. Moreover, the existence time is almost optimal if the initial perturbation over the equilibrium is sufficiently small. We have performed careful numerical study to validate our theoretical results. Well-resolved numerical study of the three-dimensional vortex sheet equation is difficult due to the complexity in evaluating the interface velocity. To alleviate this difficulty, we introduce two model equations. An important feature of these models equations is that they can be expressed in terms of convolution operators and consequently they can be computed efficiently by Fast Fourier Transform. Moreover, we show by asymptotic analysis that these model equations preserve the singularity type of the full equations. Our analysis also suggests that the model equations generate the same local form of curvature singularity near the physical singularity time as that of the full equations. Our detailed numerical computations on the two-dimensional problem show that the model equation captures all the essential singularity behavior of the full vortex sheet equation. Our calculations based on the three-dimensional model equation provide convincing evidences that a curvature singularity develops in finite time in the three-dimensional vortex sheet. And the type of the singularity is of order -1/2 in the mean curvature."
