Generation of pulsed dual wavelength erbium doped fiber laser
… fiber Bragg grating (FBG) in single ring and Figure-8 configurations at 1550 nm and 1560 nm. Analysis and optimization on single wavelength fiber laser and single wavelength pulsed fiber laser give a peak power of -10.70 dBm (8.51x10-2 mW) and -54.01 dBm (3.97x10-6 mW) with signal to noise …

Quantification of bone using a 3.0 tesla clinical magnetic resonance scanner
… good correlation with pQCT data (e.g. Figure 8-2 & Figure 8-3) and were also able to differentiate between HBM-affected and control populations (e.g. Figure 8-26). The MR data from lumbar vertebrae also demonstrated good correlation with DEXA data and some of the measurements were also …

Chaotic advection and mixing in a western boundary current-recirculation system : laboratory experiments
… a single recirculation and a double, figure-8, recirculation. The latter case involves a hyperbolic point, while the former does not. I investigate the stirring and mixing under both steady and unsteady forcing. I quantify the mixing in each case using effective diffusivity, Keff, and …

Heat and mass transfer models of the University of Tennessee at Chattanooga distillation column
… overhead receiver and a reboiler as shown on figure 8. In this thesis, mathematical models that relate to heat and mass transfer during a binary distillation of methanol-water mixture are developed and simulated through analytical and numerical methods [1]. Collections of these models were …

Assessment of the petroleum generation potential of the Neal Shale in the Black Warrior Basin, Alabama
… rather than by thermal maturity alone (Figure 8). Kinetic porosity modeling indicates the formation developed as much as 4.82% kerogen porosity. However, kinetic porosity models like the one used in this study may not be valid because they do not account for the chemical composition of …

The effects of multi-directional loading on soil liquefaction
… states, in the tests with circular, oval and figure-8 loading paths but do not fall on a cone in uni-directional and bi-directional linear tests. The effects of multi-directional loading on soil liquefaction were further investigated from the perspective of liquefaction criteria, liquefaction …

Geology of the Phil Pico Mountain Quadrangle, Daggett County, Utah, and Sweetwater County, Wyoming
… periods of uplift in the middle and late Eocene (Figure 8, Figure 24, Appendix 1). The approximate post-Paleocene throw of the Henrys Fork fault at Phil Pico Mountain is 2070 m (6800 ft). The Carson Peak Unit 1 well also reveals that just north of the Henrys Fork fault at Phil Pico Mountain the …

Radical cyclization approach to a chemoenzymatic synthesis of morphine
… the ten-membered silicon-containing epoxide [figure 1], the diene diol [figure 2], and the known oxazolone [figure 3]. See: Figures 1, 2, and 3 Diene diol [figure 2] was isolated in the amount of 200 mg/L from the fermentation of (2-bromoethyl)benzene by Pseudomonas putida 39/D (Pp 39/D) and …

A Low-Cost Unmanned Aerial Vehicle Research Platform: Development, Modeling and Advanced Control Implementation
… one formed from seven primitives exhibiting a figure-8 geometric path and another composed of a Split-S maneuver that settles into a level-turn trim trajectory. Switched control systems stemming from l2-induced norm synthesis approaches are designed for discrete-time linearized models of the …

Electromagnetic Field Modeling of Transcranial Electric and Magnetic Stimulation: Targeting, Individualization, and Safety of Convulsive and Subconvulsive Applications
… expense of inducing wider electric field spread. Figure-8 type coils are fundamentally more focal compared to circular type coils. Understanding the depth--focality tradeoff can help researchers and clinicians to appropriately select coils and interpret TMS studies. This work also enables the …

Achieving Complex Motion with Fundamental Components for Lamina Emergent Mechanisms
<p>Designing mechanical products in a competitive environment can present unique challenges, and designers constantly search for innovative ways to increase efficiency. One way to save space and reduce cost is to use ortho-planar compliant mechanisms which can be made from sheets of material, or …
