HYPERION: A HYdrogen PERmeatION Experiment to Quantify Hydrogen Transport in Fusion-Relevant Molten Salts
… and assembling a HYdrogen PERmeatION (HYPERION) experiment and provides preliminary results of the functionality as well as some issues and troubleshooting of the experiment. Using the code Finite Element Simulation of Tritium In Materials (FESTIM), the experiment was also modeled. The …

Negative Capability in the Characters of Keats' Magor Poetry
… poems are discussed: "Ode to a Nightingale, Hyperion, and Lamia. The discussions focus primarily on these three points: (1) the degree to which each character possesses "negative capability" (i.e., his ability for self-negation, empathic-identification, and disinterestedness); (2) the …

A steady-state L-mode tokamak fusion reactor : large scale and minimum scale
… major radius) hydrogen production reactor dubbed HYPERION. Due to the potentially prohibitive capital cost (a $50 billion) and exorbitant thermal power (a 35 GWth) of HYPERION, we identify a conservative estimate for the minimum scale of a similar steady-state L-mode reactor of approximately 7.5 …

Using satellite hyperspectral imagery to map soil organic matter, total nitrogen and total phosphorus
… using Analytical Spectral Devices spectrometer. Hyperion images for each of the watersheds were acquired, calibrated and corrected and Hyperion image spectra for individual sampled sites were extracted. These hyperspectral reflectance data were related to SOM, total N and total P concentration …

Prediction of Foliar Biochemistry in a Boreal Forest Canopy Using Imaging Spectroscopy and LiDAR Data
… errors. Predictive models using spaceborne Hyperion IS data were developed with adjusted R2 values of 0.73, 0.72, 0.62, 0.25, and 0.67 for N, P, K, Ca and Mg, respectively. The LiDAR model explained 80% of the variance in canopy Ca concentration with an RMSE of less than 10%, suggesting …

Manifold learning based spectral unmixing of hyperspectral remote sensing data
… amounts, they are not effective with noisy Hyperion data because the effect of residual striping artifacts is amplified in ratios involving band differences. In this case study, spectral unmixing techniques are investigated for estimating crop residue as an alternative approach to empirical …

Arid land condition assessment and monitoring using mulitspectral and hyperspectral imagery.
… scenes of Landsat TM and ETM+ multispectral and Hyperion hyperspectral data were acquired over the study area. The imagery was acquired in dry seasons to highlight perennial vegetation cover that has an important role in land condition assessment and monitoring. Slope-based, distance-based, …

Estimating the water quality condition of river and lake water in the Midwestern United States from its spectral characteristics
… in southern Lake Michigan. One set of EO-1 Hyperion imagery and one set of boat-based spectrometer measurements were successfully acquired to capture episodic plume events. Coincident water quality measurements were also collected during these plume events. A database of inherent optical …

Remote Sensing of Hydrocarbon-induced Rock Alterations at Cement Field, Oklahoma
… 8 and ASTER multispectral data, as well as Hyperion and Specim hyperspectral imagery. Published geologic maps and geochemical data were combined to show the geologic extent and various degrees of rock alterations. Petrographic analysis showed bleaching and cementation of sandstones, as well …

Assessing The Biophysical Naturalness Of Grassland In Eastern North Dakota With Hyperspectral Imagery
… imagery.</p> <p>Hyperspectral imageries from the Hyperion sensor on EO-1 were acquired in late spring and late summer on 2009 and 2010. Field spectra for widely distributed species as well as smooth brome grass and Kentucky blue grass were collected from the study sites throughout the growing …

Detection of rare earth elements and rare earth oxides with hyperspectral spectroscopy
… adapted to different hyperspectral sensors (EO-1 Hyperion and EnMAP) and a new test site (Lofdal, Namibia). Additionally, the hyperspectral signatures of associated minerals were investigated to serve as proxy for the host rocks. Finally, the capacity and limitations of spectroscopic rare earth …
