Simeral, Anthony A. Mrse, Jan L. Eilertsen, Lacramioara Negureanu, Zhehong Gan, Frank R. Fronczek, Randall W. Hall, Leslie G. Butler

Randall W. Hall

The first structurally characterized isobutyl-containing aluminoxane compound is presented. The Al10O6iBu16(μ-H)2 (I) cluster is produced from neat octakis-isobutyltetraluminoxane (Al4O2iBu8) at 80 °C in 6−8 h followed by slow crystallization. The crystal is triclinic (space group P1̄) with the molecule lying on an inversion center. This aluminoxane contains both nearly linear, 154(2)°, aluminum-bridging hydrides and three-coordinate aluminum sites. Solid-state 27Al magic-angle spinning (MAS) NMR experiments were done at 19.6 and 40 T (833 MHz and 1.703 GHz, 1H) and at 30−35 kHz spinning speeds, leading to the determination of the Cq and η values for the two four-coordinate Al sites and …

Preliminary Model Tests For The Design Of A Gliding Deep Water Elevator, Christopher Roman, T. Gregory, E. Martin, A. Sanguinetti, J. Drummond Aug 2007

Preliminary Model Tests For The Design Of A Gliding Deep Water Elevator, Christopher Roman, T. Gregory, E. Martin, A. Sanguinetti, J. Drummond

Christopher N. Roman

This paper presents progress on the design of a "smart elevator" to be used in conjunction with deep sea ROV operations. Deep sea elevators are gravity driven untethered platforms used to deliver and or return items from the sea floor. Elevators are used when items are too large or heavy to be handled by the ROV, or when the turn around time to recover and redeploy the ROV system for sample removal is prohibitive. Unfortunately, efficiency is complicated by the precision with which elevators can be landed at a specific location on the bottom and recovered on the surface because …


Mitigation Of Biases Using The Schmidt-Kalman Filter - Art. No. 66990q, Randy Paffenroth, Roman Novoselov, Scott Danford, Marcio Teixeira, Stephanie Chan, Aubrey Poore Aug 2007

Mitigation Of Biases Using The Schmidt-Kalman Filter - Art. No. 66990q, Randy Paffenroth, Roman Novoselov, Scott Danford, Marcio Teixeira, Stephanie Chan, Aubrey Poore

Randy C. Paffenroth

Fusion of data from multiple sensors can be hindered by systematic bias errors. This may lead to severe degradation in data association and track quality and may result in a large growth of redundant and spurious tracks. Multi-sensor networks will generally attempt to estimate the relevant bias values (usually, during sensor registration), and use the estimates to debias the sensor measurements and correct the reference frame transformations. Unfortunately, the biases and navigation errors are stochastic, and the estimates of the means account only for the "deterministic" part of the biases. The remaining stochastic errors are termed "residual" biases and are …

Spin Effects In The Effective Quantum Field Theory Of General Relativity, A Ross, Br Holstein Jun 2007

Spin Effects In The Effective Quantum Field Theory Of General Relativity, A Ross, Br Holstein

Barry R Holstein

The calculation of gravitational scattering of particles with various spin configurations in the framework of effective quantum field theory of general relativity is presented. We find that the long-range quantum and classical corrections to the spin-independent piece and the spin–orbit coupling piece of the scattering amplitude and the scattering potential are universal for different spin configurations, which leads us to propose this universality to be true for arbitrary spins. Furthermore, we give the leading corrections to the spin–spin coupling, and a comparison with scattering in QED is made.


Design Of A Gas Tight Water Sampler For Auv Operations, Christopher Roman, R. Camilli May 2007

Design Of A Gas Tight Water Sampler For Auv Operations, Christopher Roman, R. Camilli

Christopher N. Roman

This paper presents the design and preliminary test results for a small gas tight water sampler intended to work on scientific AUVs. In recent years AUVs have developed into reliable platforms capable of carrying a wide variety of environmental sensors for in-situ chemical measurements. Physical sample collection however remains difficult, due to the combination of space, power and complexity constraints inherent in working with autonomous platforms. The AUV sampler is a small (12 cm times 85 cm) cylindrical package designed to collect eight 20 ml gas tight volumes of water, with each sample maintained at high pressure to depths of …

Land Cover Classification And Economic Assessment Of Citrus Groves Using Remote Sensing, Jennifer Gebelein Jan 2007

Land Cover Classification And Economic Assessment Of Citrus Groves Using Remote Sensing, Jennifer Gebelein

Jennifer Gebelein

The citrus industry has the second largest impact on Florida's economy, following tourism. Estimation of citrus area coverage and annual forecasts of Florida's citrus production are currently dependent on labor-intensive interpretation of aerial photographs. Remotely sensed data from satellites has been widely applied in agricultural yield estimation and cropland management. Satellite data can potentially be obtained throughout the year, making it especially suitable for the detection of land cover change in agriculture and ...
