This report describes research on noncognitive measures for screening Army recruiters with potential application to other Noncommissioned Officer (NCO) assignments. One limitation has been that previously validated instruments for this purpose required proctored testing. To make it easier for Soldiers to be tested, reduce costs, and build upon previous work, ARI was requested to assist with the following: (1) developing a computerized, noncognitive measure suitable for unproctored administration; and (2) validating this instrument against measures of recruiter performance. This new instrument is called the Noncommissioned Officer Special Assignment Battery (NSAB). The NSAB is a computer-adaptive, forced-choice assessment that incorporates recent advances in noncognitive measurement that have been shown to be highly faking resistant and suitable for high-stakes testing environments. The NSAB has 18 scales. Results from a sample of 1,032 experienced Army recruiters indicated that Soldiers with high NSAB composite scores reported the following: (1) lower job stress, and (2) higher satisfaction with recruiting duty. These high-scoring recruiters also were rated by their peers and supervisors as performing better than recruiters with lower NSAB composite scores. These findings indicate that the NSAB can help to identify Soldiers with high potential for recruiting duty success, and it also has the potential for screening in other NCO assignments.

THOR is a radiation transport code that solves the steady-state, multigroup, discrete ordinates approximation of the linear Boltzmann equation in three-dimensional geometry on unstructured tetrahedral cells. The spatial approximation implemented in THOR is the Arbitrarily High Order Transport method of the Characteristic type, AHOTC, extended to Unstructured Grids, AHOTC-UG. The tasks of this project were designed to raise the production level of THOR by supplementing its capabilities then conducting a comprehensive Verification and Validation (V&V) exercise based on Idaho National Laboratory's (INL) Advanced Test Reactor (ATR) configuration and measured data. The primary development work on the code commenced with a study of numerical stability of the underlying equations in the optically-thin cell limit that revealed the cause for the structural instability observed in earlier results. Basically the recursive algorithm used in evaluating the flux spatial moments in terms of lower-order moments accumulated the error to unacceptable magnitude for higher orders. This deficiency was addressed by reformulating the equations and subsequent solution algorithm into a non-recursive form that was found to be numerically stable with increasing spatial expansion order. Additionally we examined the numerical stability of the spatial weights associated with AHOTC-UG and constructed asymptotic expansions that are resilient in the optically thin and thick cell regimes. Many improvements intended to enhance THORs robustness and computational efficiency were implemented, including a cycle-breaking algorithm that may be necessary in some complex automatically-generated unstructured grids.

The most vital components in polymer electrolyte membrane (PEM) fuel cells are PEM materials. In the case of Nafion (DuPont Co.), the most widely used PEMs, the proton conductivity markedly decreases at high temperature ( > 80 ℃) and low relative humidity (RH) ( < 30%). This drawback limits the use of Nafion in practical and commercial applications. Our research group is developing the Nafion-alternative PEMs by using a radiation-induced grafting method1'. In these PEMs, the graft chain structures should significantly affect the proton conduction properties. Then, in this study, by combination of radiation grafting and atom transfer radical polymerization (ATRP), we designed the novel PEMs possessing both the hydrophobic and hydrophilic graft chains.

This report describes the redesign and demonstration of an experiment, developed by the Natick Soldier Research, Development and Engineering Center (NSRDEC), to measure the response of energy absorbing materials behind a buffer material, loaded with the shockwave and dynamic pressure pulse in a shock tube. This test has application in the development of body armor for blast attenuation and impact attenuation. Foam materials are rapidly compressed between the striker (buffer) and fixed test plate at dynamic strain rates reaching peak levels between 500-1000/s. Foam stress is calculated by measuring the reaction force of the material with a dynamic load cell. Foam compression is measured through high speed video image analysis. With the current experimental set-up, the material test results are very similar to those obtained with a drop weight impact test.

Advances in the understanding of multiphase flow characteristics under variable gravity conditions will ultimately lead to improved and as of yet unknown process designs for advanced space missions. Such novel processes will be of paramount importance to the success of future manned space exploration as we venture into our solar system and beyond. In addition, because of the ubiquitous nature and vital importance of biological and environmental processes involving airwater mixtures, knowledge gained about fundamental interactions and the governing properties of these mixtures will clearly benefit the quality of life here on our home planet. The techniques addressed in the current research involving multiphase transport in porous media and gas-liquid phase separation using capillary pressure gradients are also a logical candidate for a future International Space Station (ISS) flight experiment. Importantly, the novel and potentially very accurate Lattice-Boltzmann (LB) modeling of multiphase transport in porous media developed in this work offers significantly improved predictions of real world fluid physics phenomena, thereby promoting advanced process designs for both space and terrestrial applications.This 3-year research effort has culminated in the design and testing of a zero-g demonstration prototype. Both the hydrophilic (glass) and hydrophobic (Teflon) media Capillary Pressure Gradient (CPG) cartridges prepared during the second years work were evaluated. Results obtained from ground testing at 1-g were compared to those obtained at reduced gravities spanning Martian (13-g), Lunar (16-g) and zero-g. These comparisons clearly demonstrate the relative strength of the CPG phenomena and the efficacy of its application to meet NASAs unique gas-liquid separation (GLS) requirements in non-terrestrial environments.LB modeling software, developed concurrently with the zero-g test effort, was shown to accurately reproduce observed CPG driven gas-liquid separation phenomena. The design and fabrication of a micropost plate-lamina Hele-Shaw (HS) cell was performed which served as a computationally attainable geometric structure facilitating direct comparison between physical phenomena observed in our laboratory and the LB software predictions.

In an effort to characterize the dynamics typical of school bus operation, National Renewable Energy Laboratory (NREL) researchers set out to gather in-use duty cycle data from school bus fleets operating across the country. Employing a combination of Isaac Instruments GPS/CAN data loggers in conjunction with existing onboard telemetric systems resulted in the capture of operating information for more than 200 individual vehicles in three geographically unique domestic locations. In total, over 1,500 individual operational route shifts from Washington, New York, and Colorado were collected. Upon completing the collection of in-use field data using either NREL-installed data acquisition devices or existing onboard telemetry systems, large-scale duty-cycle statistical analyses were performed to examine underlying vehicle dynamics trends within the data and to explore vehicle operation variations between fleet locations. Based on the results of these analyses, high, low, and average vehicle dynamics requirements were determined, resulting in the selection of representative standard chassis dynamometer test cycles for each condition. In this paper, the methodology and accompanying results of the large-scale duty-cycle statistical analysis are presented, including graphical and tabular representations of a number of relationships between key duty-cycle metrics observed within the larger data set.

We describe one-dimensional (1D) photonic crystals that support a guided mode suitable for atom trapping within a unit cell, as well as a second probe mode with strong atom photon interactions. A new hybrid trap is analyzed that combines optical and Casimir Polder forces to form stable traps for neutral atoms in dielectric nanostructures. By suitable design of the band structure, the atomic spontaneous emission rate into the probe mode can exceed the rate into all other modes by more than tenfold. The unprecedented single- atom reflectivity r0 >/approximately 0.9 for the guided probe field should enable diverse investigations of photon-mediated interactions for 1D atom chains and cavity quantum electrodynamics.
