Interactions between surface winds and meanders in mid-latitude sea surface temperature
(SST) fronts with horizontal length scales of 100-1000 km are investigated
from satellite observations and numerical simulations. Observations from the Sea-
Winds scatterometer on the QuikSCAT satellite show that the magnitude, direction,
curl, and divergence of the surface wind...
Responses of biological indicators of soil quality to winter cover cropping were measured on soil samples collected from 6 commercial growers' fields and two experiment research stations in the Willamette Valley of Oregon. The research stations were the North Willamette Research and Extension Center (Aurora, OR), and the Oregon State...
More efficient methods are needed for the in-situ evaluation of mass transfer parameters which describe the movement of solutes through aquifer material. The objective of this study was to develop a method for estimating diffusion rate and capacity coefficients using a single-well, "push-pull" tracer test. The method consists of the...
For the purpose of investigating the fundamental nature of the
interannual oscillation observed in the tropical Pacific in conjunction with
El Nino/Southern Oscillation (ENSO), the Comprehensive Ocean
Atmosphere Data Set was analyzed. Based upon this analysis, an
"intermediate" tropical atmosphere-ocean coupled model was developed.
For reason of their particular importance...
A simple atmosphere and ocean model of relevance to El Nino
and Southern Oscillation (ENSO) is discussed. Both the
atmosphere and ocean models are two layer, three
dimensional, linear and baroclinic, and generally follow
the Oregon State University coupled general circulation
model. However, the parameterization differs considerably
from previous work...
In this work we consider two multiscale applications with tremendous computational complexity at the lower scale. First, we examine a model for charge transport in semicon- ductor structures with heterojunction interfaces. Due to the complex physical phenomena at the interface, the model at the design scale is unable to adequately...
Protein-protein interactions underlie all biological processes and are a field of study that has wide implications throughout many other fields including medicine, genetics, biology, and ecology. Proteins are the building blocks and primary actors of life. They work together to accomplish virtually every task within a cell, including, metabolism, signal...
In chapter 3 of our paper we present equations of motion for continuous mass
distribution subject to hydrodynamic forces in their most general form. We start
with equations for discrete mass particles and then transform the equations so
that it is appropriate for a continuous mass distribution. As we do...
Droplet formation from a rigid and a vibration nozzle driven by a pulsing pressure is simulated. Droplet formation is simulated by using one-dimensional model. For the case of droplet formation from a vibration nozzle, the nozzle vibration is simulated by large deflection plate vibration equation. Droplet formation from a rigid...
