The use of natural and nature-based features for coastal hazard mitigation, particularly emergent vegetation such as mangrove forests, have become increasingly popular. However, the protection that these systems can provide has not been fully quantified for engineering design, and the uncertainties in parameterized equations have not been fully defined. In...
Two examples of Pacific rim plate boundary deformation are presented. In the first
part of the thesis crustal models are derived for the northwestern part of the Vizcaino
block in California using marine seismic and gravity data collected by the Mendocino
Triple Junction Seismic Experiment. A northwest-southeast trending kink in...
As a result of the automation revolution, robots
are assuming ever more complex and demanding tasks.
Robot system control schemes for fast and precise robot
motion require utilization of the entirety of the robot
dynamic formulations and the ability to evaluate these
formulations in real-time. The dynamic formulations,
which take...
In this thesis anomalous downcore shallowing of paleomagnetic
inclinations is interpreted to be caused by sediment compaction. Thus,
compaction-induced inclination shallowing may influence tectonic
reconstructions that are based on inclinations from deep-sea sediment
cores.
Progressive downcore shallowing of the remanent inclination was
observed in a 120-m section of Plio- Pleistocene...
The word orogenesis is derived from the Greek words oros meaning mountains and genesis meaning creation and refers to the study of the complex processes involved in the growth and evolution of mountain ranges (orogens). Orogens develop where crustal deformation builds topography and forms landscapes. This dissertation explores the role...
A challenge for municipal authorities of growing urban areas is to provide larger and faster transportation and utility networks that are safe and resilient to significant disruptions after an earthquake event and other disasters. Urban regions, like the San Francisco Bay or the Los Angeles area, are situated in seismically...
A MOS biquadratic (biquad) filter employing the switched-current technique is
reported. The circuit uses current-mode processing which can offer wide
bandwidth, low voltage operation, and can be implemented with standard CMOS
technology. Examples of lowpass, highpass, and bandpass filters are given
which illustrate the synthesis procedures and the versatility of...
In this paper we outline a procedure we use for routine moment-tensor analysis of regional data from broadband seismic stations in northwestern North America and apply it to the moment magnitude 5.5, March, 1993, Scotts Mills, Oregon, earthquake. The results compare favorably with those obtained from teleseismic data. We found...
The way of slip transformation and strain partitioning at the eastern termination of the Kunlun
fault system remains unclear, and the question of whether this fault system is an important part for
lateral extrusion of Tibetan crust is debatable. The Tazang fault is regarded as the easternmost
continuation of the...
