Ridge waves
Second-class wave propagation along mid-ocean ridges is investigated in an effort to explain subinertial peaks found in the velocity spectra over the Juan de Fuca Ridge (JdFR, 4 days) and the Iceland-Faeroe Ridge (IFR, 1.8 days). Topographic cross sections of the ridges are fit by a …

Molluscan paleontology of the Pliocene Peace Valley "beds" and Ridge Route "formation" (Ridge Basin group), Ridge Basin, southern California
<p>The Ridge Basin, 90 km northwest of Los Angeles, California, lies within the San Gabriel, San Andreas, Liebre, and Clearwater fault zones. The basin is an elongated, wedge-shaped, intermontane, Miocene-Pliocene basin filled with about 12 000 m of marine, lacustrine, fluvial, and alluvial …

The Little People of Pea Ridge
… to steep, wooded hillsides and rough, rocky ridge tops. Areas often take part of their names from outstanding topographic features of the land. Community names such as White's Bottom, Howard's Bottom, Cherry Tree Ridge and Bow Schoolhouse Ridge are common in Cumberland County. On Pea Ridge, …

Vortices of the Mozambique ridge current
During a cruise of the R.V. Meiring Naude in August 1975, anomalous values for temperature, salinity and nutrients were recorded over a deep-sea region of the Southwestern Indian Ocean. It was thought that this oceanographic anomaly may represent part of a cyclonic mesoscale vortex of unknown …

Influence of suture technique on ridge dimensions and keratinized tissue after alveolar ridge preservation: a pilot study
The alveolar ridge preservation (ARP) procedure was designed to minimize bone loss following tooth extraction to allow for implant placement in the prosthetically-driven position, and reduce the need for subsequent grafting procedures. The aim of this study was to evaluate how two suturing …

The geochemistry of selected mid-ocean ridge basalts from the Southern mid-Atlantic ridge (40°- 55°S)
… from this section of the southern Mid-Atlantic Ridge (SMAR), and significantly expanded the global suite of samples from slow-spreading ridges.

Mantle Heterogeneity Through Mid-Ocean Ridge Basalts
… upper mantle is often examined through mid-ocean ridge basalts (MORB), which contest the prevalent assumption of a well-mixed convecting mantle. This dissertation delves into studying mantle heterogeneity from a local to regional scale. Initially, petrological models were utilized to scrutinize …

Simulation-based Design with Polynomial Ridge Approximations
… we explore the use of orthogonal polynomial ridge approximations to construct surrogate models. These models enable rapid evaluations and facilitate a deeper, physically-intuitive understanding of the quantities of interest. For modelling smoothly varying functions, the use of orthogonal …

Comparison of ridge and other shrinkage estimation techniques
… the shrinkage factors is proposed and applied on ridge and generalized ridge regression. We propose that the new shrinkage factors should be based on the principal components instead of the unstable OLS estimates.

Sticks and stones: a Blue Ridge Mountain retreat
Given a sloping wooded site in the Blue Ridge Mountains of North Carolina, the problem of the thesis project was to design a retreat that would fit the environment and the people that would inhabit it. It was a searching for the interdependence between the landscape and the building. Equally …

Testing the Origins of the Blue Ridge Escarpment
… shifts or tectonic rejuvenation. The Blue Ridge Escarpment, eastern North America's great escarpment, is no different. A number of hypotheses attempt to explain the Blue Ridge Escarpment. These include lithologic variation between Blue Ridge and Piedmont rocks, the distance to ultimate base …

Aquifer Characterization in the Blue Ridge Physiographic Province
Existing models of the hydrogeology in the Blue Ridge Province in the eastern United States generally assume a simplified two-layered system consisting of shallow unconsolidated and relatively homogeneous and porous regolith with a water-table aquifer that slowly supplies water downward to the …

A Ridge-fed Conical Horn Antenna for Small Satellites
<p>The increased popularity of small satellites such as CubeSats as an alternative vehicle for efficient and low cost space exploration has revolutionized the space research industry. The small physical size and other constraints owing to outer space applications has presented a myriad of exciting …

Fluid Flow Processes at Mid-Ocean Ridge Hydrothermal Systems
… structure and temporal variability of mid-ocean ridge hydrothermal systems are examined from a largely theoretical standpoint. The nature of tidal signals is considered in detail and there is a discussion of the mechanisms by which the tidal modulations observed at seafloor hydrothermal systems …
