The restoration of rivers and streams should be based on a
strong conceptual framework. Streams are developing systems. As
such, streams exhibit temporal behaviors that change with changing
stream environments. Underlying the dynamic development of streams is
potential capacity. Streams express this capacity as an array of
habitats over time...
The vertical and radial components of a seismic P wave can be
decomposed by a Fourier transform into two sets of nonterminating
sinusoidal waves with one set for each component. The tangent of the
vertical transform divided by the radial transform gives by definition
he apparent angle of emergence for...
While hydrophobic surfaces coated with the poly[ethylene oxide]-poly[propylene oxide]-poly[ethylene oxide] (PEO-PPO-PEO) surfactant Pluronic® F108 are highly resistant to plasma protein adsorption, the antimicrobial peptide nisin has been observed to adsorb in multilayer quantities at such surfaces, and the PEO chains themselves suggested to inhibit nisin exchange by blood proteins. But...
Infections in hospitals account for over 100,000 deaths per year. These infections occur at the
hospital from complications following bacterial adhesion to intravenous catheters, coronary
stents and other implanted devices. Another common problem is protein adsorption to the
surface of the device and subsequent blood clotting. Methods for combating these...
This dissertation presents novel, field-activated smart material systems for the actuation and control of autonomous robots. Smart materials, a type of material whose properties can be changed with an external stimuli, represent a promising direction to expand upon existing robotic control and actuation methods, particularly in the sub-fields of soft...
This thesis serves as a literature review of dashboards that calls for further research in the area of Feedback Mechanisms (FMs). A dashboard, for the purposes of this paper is a display used to provide performance feedback to a user. An FM is the mechanism used in a dashboard to...
The first cycle of seismic waves recorded at distances of 45,
300 and 355 km. from the GNOME nuclear explosion was used to determine
whether the near source wave characteristics at 0.3 km.
could be determined from distance measurements. Both head wave
and body wave propagation were considered. First the...
