Multiple-access phased array antenna simulator for a digital beam forming system investigation

Future versions of data relay satellite systems are currently being planned by NASA. Being given consideration for implementation are on-board digital beamforming techniques which will allow multiple users to simultaneously access a single S-band phased array antenna system. To investigate the potential performance of such a system, a laboratory simulator has been developed at NASA's Lewis Research Center. This paper describes the system simulator, and in particular, the requirements, design, and performance of a key subsystem, the phased array antenna simulator, which provides realistic inputs to the digital processor including multiple signals, noise, and nonlinearities

Assessing Spiritual Development in Business Students: Lessons Learned and a Suggested Process

As Christian higher education institutions increasingly engage in continuous quality improvement and outcome measurement, research on spiritual development is filtering down to undergraduate business programs. This paper presents lessons learned from a pilot cross-sectional survey of Abilene Christian University undergraduate business students who completed the Faith Maturity Scale (Benson, Donahue & Erickson, 1993) and responded to other questions about faith development. Based on the results, a number of helpful observations were made for the ACU business program. A method and process for assessing spiritual development at multiple Christian colleges is proposed

Novel Space Alters Theta and Gamma Synchrony Across the Longitudinal Axis of the Hippocampus.

Hippocampal theta (6–10 Hz) and gamma (25–50 Hz and 65–100 Hz) local field potentials (LFPs) reflect the dynamic synchronization evoked by inputs impinging upon hippocampal neurons. Novel experience is known to engage hippocampal physiology and promote successful encoding. Does novelty synchronize or desynchronize theta and/or gamma frequency inputs across the septotemporal (long) axis of the hippocampus (HPC)? The present study tested the hypothesis that a novel spatial environment would alter theta power and coherence across the long axis. We compared theta and gamma LFP signals at individual (power) and millimeter distant electrode pairs (coherence) within the dentate gyrus (DG) and CA1 region while rats navigated a runway (1) in a familiar environment, (2) with a modified path in the same environment and (3) in a novel space. Locomotion in novel space was related to increases in theta and gamma power at most CA1 and DG sites. The increase in theta and gamma power was concurrent with an increase in theta and gamma coherence across the long axis of CA1; however, there was a significant decrease in theta coherence across the long axis of the DG. These findings illustrate significant shifts in the synchrony of entorhinal, CA3 and/or neuromodulatory afferents conveying novel spatial information to the dendritic fields of CA1 and DG targets across the long axis of the HPC. This shift suggests that the entire theta/gamma-related input to the CA1 network, and likely output, receives and conveys a more coherent message in response to novel sensory experience. Such may contribute to the successful encoding of novel sensory experience

Value Chain Development With The Extremely Poor: Evidence And Lessons From CARE, Save The Children, And World Vision

CARE, Save the Children, and World Vision are combining value chain development (VCD) with gender and nutrition programming to alleviate poverty and food insecurity among the extremely poor. We explore what is unique about VCD with the extremely poor and how specific levers enhance productivity and profitability, equity, and empowerment. We offer evidence to date and lessons learned

Oil film interferometry in high Reynolds number turbulent boundary layers

There is continuing debate regarding the validity of skin friction measurements that are dependent on the functional form of the mean velocity profile, for example, the Clauser chart method. This has brought about the need for independent and direct measures of wall shear stress, tw. Of the independent methods to measure tw, oil film interferometry is the most promising, and it has been extensively used recently at low and moderately high Reynolds number. The technique uses interferometry to measure the thinning rate of an oil film, which is linearly related to the level of shear stress acting on the oil film. In this paper we report on the use of this technique in a high Reynolds number boundary layer up to Rq = 50,000. Being an independent measure of tw, the oil film measurement can be used as a means to validate more conventional techniques, such as the Preston tube and Clauser chart at these high Reynolds numbers. The oil-film measurement is validated by making comparative measurements of tw in a large-scale fully-developed channel flow facility where the skin friction is known from the pressure gradient along the channe

180 diffusion through amorphous SiOs and cristobalite

Secondary ion mass spectrometry was used to profile the diffusion of oxygen in polycrystalline β-cristobalite and vitreous SiO2. The tracer concentration profiles of cristobalite are consistent with a model based on two mechanisms: bulk and short-circuit diffusion. The profiles of partially crystallized samples containing vitreous SiO2 and β-cristobalite were fitted using the sum of two complementary error functions and taking account of some interstitial-network exchange. The bulk oxygen diffusivity, in the temperature range 1240-1500 °C, is about five times greater for vitreous silica than for β-cristobalite
