This dissertation consists of four parts. The first part deals with the response of liquid storage tanks to a vertical component of ground motion. Galerkin's method is used to solve this problem approximately, and its accuracy is established by comparing the results with those obtained by the exact modal superposition method. The effects of soil ...

The elastic and inelastic responses of the force-excited single-degree-of-freedom (SDOF) systems are investigated from the gross characteristics of forcing functions such as the frequency content, the integrals and the amplitudes. The studies are carried out initially with simple version of force-excitation and then, using progressively complicated ...

Response nonnormality is investigated for a yielding primary structure and a linear secondary system (P-S) subjected to a normally distributed ground acceleration. The nonlinearity considered is bilinear hysteretic (BLH) yielding in the primary structure. The coefficient of excess (COE), which is a normalized fourth cumulant function, is used as a ...

This thesis deals with the effects of soil-structure interaction, both kinematic and inertial, on the responses of seismically excited rectangular foundations and simple structures supported on such foundations. The ground motion considered is defined stochastically by a local power spectral density function and a spatial incoherence function. The ...

This dissertation presents a comprehensive study of the dynamic response of storage tanks containing high-level radioactive wastes in nuclear facilities. Of the many issues that are peculiar to these systems, four important ones have been studied. Accordingly, the study is presented in four parts. The first part deals with the dynamic response of ...

The settling velocity of aggregates found in engineered water and wastewater treatment facilities are usually assumed to follow Stokes' law. These particles, however, are typically porous and may be fractal in nature. As a result, they have very different sedimentation characteristics. This study focuses on the comparison of several techniques used ...

A process for purification of the previously insoluble empty fullerenes and endohedral metallofullerenes was developed, based on sublimation from the soot and subsequent solubilization by electrochemical reduction. The newly purified fullerenes were shown to have small gaps between filled and unfilled electronic states. They are expected to be ...

Absolute differential and integral charge transfer cross sections have been measured for 0.5, 0.85, 1.5, 2.8, and 5.0 keV O$\sp+$ with O$\sb2$ at scattering angles between 0.01$\sp\circ$ and 3.50$\sp\circ$ in the laboratory frame. The dependence of these cross sections upon the electronic state of the O$\sp+$ ion was investigated. This study was ...

This thesis studies the performance of multistage interconnection networks (MINs) using execution-driven simulation. The networks were studied with varying network configurations, numbers of inputs and outputs of the network switches, sizes of the switch buffers, switch transmission and arbitration delays, bus sizes in the case of a hybrid switch-bus ...

Using immunocytochemical and electrophysiological methods, the effects of mutations in the structural gene for a calcium activated potassium channel, slowpoke (slo), in Drosophila melanogaster were studied. Anti-horseradish peroxidase was used to visualize the branching of the nerves innervating the body wall muscles. No differences are observed ...
