Electron Density And Electron Neutral Collision Frequency In The Ionosphere Using Plasma Impedance Probe Measurement, E. Spencer, S. Patra, T. Andriyas, C. Swenson, J. Ward, A. Barjatya

Publications

Swept Impedance Probe measurements in a sporadic E layer observed during the Sudden Atomic Layer (SAL) sounding rocket mission are analyzed to obtain absolute electron densities and electron neutral collision frequencies accurately. Three sets of upleg and downleg impedance data are selected for the analysis. Initial estimates of the plasma parameters are obtained through a least mean square fit of the measured impedance data against the analytical impedance formula ZB(f ) of Balmain (1969). These initial parameters are used as a starting point to drive a finite difference computational model of an antenna immersed in a plasma called PF-FDTD. The …

Promoting Teamwork: An Event-Based Approach To Simulation-Based Teamwork Training For Emergency Medicine Residents, Michael A. Rosen, Eduardo Salas, Teresa S. Wu, Salvatore Silvestri, Elizabeth H. Lazzara, Rebecca Lyons, Sally J. Weaver, Heidi B. King

Publications

The growing complexity of patient care requires that emergency physicians (EPs) master not only knowledge and procedural skills, but also the ability to effectively communicate with patients and other care providers and to coordinate patient care activities. EPs must become good team players, and consequently an emergency medicine (EM) residency program must systematically train these skills. However, because teamwork-related competencies are relatively new considerations in health care, there is a gap in the methods available to accomplish this goal. This article outlines how teamwork training for residents can be accomplished by employing simulation-based training (SBT) techniques and contributes tools and …

Developing A Coherent Cyberinfrastructure From Local Campus To National Facilities: Challenges And Strategies, Amy Apon, Patrick Dreher, Vijay Agarwala, Stan Ahalt, Guy Almes, Sue Fratkin, Thomas Hauser, Jan Odegard, Jim Pepin, Craig Stewart

Publications

A fundamental goal of cyberinfrastructure (CI) is the integration of computing hardware, software, and network technology, along with data, information management, and human resources to advance scholarship and research. Such integration creates opportunities for researchers, educators, and learners to share ideas, expertise, tools, and facilities in new and powerful ways that cannot be realized if each of these components is applied independently. Bridging the gap between the reality of CI today and its potential in the immediate future is critical to building a balanced CI ecosystem that can support future scholarship and research. This report summarizes the observations and recommendations …

Excitation Of Ducted Gravity Waves In The Lower Thermosphere By Tropospheric Sources, Jonathan B. Snively, Victor P. Pasko

Publications

Short-period, small-scale gravity waves are frequently observed in nighttime airglow imaging experiments. These waves are often found to be ducted and may be confined to a thin region of altitude in the mesosphere or lower thermosphere. An apparent paradox of high-altitude ducted waves is the nature of the source; it is necessary that a ducted wave be excited in situ or have been able to tunnel into the duct from another atmospheric region. In this paper, analytical and numerical solutions are presented for simple thermally ducted gravity waves that are Doppler-shifted by constant background winds. Using a continuous analytical model, …

Forecasting Effects Of Sea‐Level Rise And Windstorms On Coastal And Inland Ecosystems, Charles S. Hopkinson, Ariel E. Lugo, Merryl Alber, Alan P. Covich, Skip J. Van Bloem

Publications

We identify a continental‐scale network of sites to evaluate how two aspects of climate change – sea‐level rise and intensification of windstorms – will influence the structure, function, and capacity of coastal and inland forest ecosystems to deliver ecosystem services (eg carbon sequestration, storm protection, pollution control, habitat support, food). The network consists of coastal wetland and inland forest sites across the US and is representative of continental‐level gradients of precipitation, temperature, vegetation, frequency of occurrence of major windstorms, value of insured properties, tidal range, watershed land use, and sediment availability. The network would provide real‐time measurements of the characteristics …

Assessing The U.S. Watershed Management Movement: National Trends And An Illinois Case Study, Leslie Duram, Tim Loftus, Jane Adams, Christopher Lant, Steven E. Kraft

Publications

Local watershed planning is an increasingly important component of environmental management. This article provides an overview of local watershed management efforts occurring across the US and then focuses on one case study from southern Illinois. First, analysis of 1145 local watershed groups shows that government agencies, farmers, and rural residents are key stakeholders in local groups that primarily deal with regional environmental stressors in the form of soil erosion, nutrients, and agrichemicals. Second, the role of watershed partnerships in mediating the complex interactions among stakeholders and local water resources are investigated through a case study of one watershed group. The …

Hypoelastic Modeling Of Reinforced Concrete Walls, Mohsen A. Shayanfar, Amir Safiey

Publications

This paper presents a new hypoelasticity model which was implemented in a nonlinear finite element formulation to analyze reinforced concrete (RC) structures. The model includes a new hypoelasticity constitutive relationship utilizing the rotation of material axis through successive iterations. The model can account for high nonlinearity of the stress-strain behavior of the concrete in the pre-peak regime, the softening behavior of the concrete in the post-peak regime and the irrecoverable volume dilatation at high levels of compressive load. This research introduces the modified version of the common application orthotropic stress-strain relation developed by Darwin and Pecknold. It is endeavored not …

An Application Of High Fidelity Ftds For Ab Initio Pilot Training: The Way Ahead, Nickolas D. Macchiarella, Tim Brady, Brandon S. Lyon

Publications

"Decreases in simulation costs and increases in aircraft training costs led to the need for further investigation into the application of simulation-based training. Researchers conducted an eighteen-month study using ab initio student pilots as participants. This study applied a Federal Aviation Administration (FAA) approved, Part 142, flight-training curriculum that included 60% flight training device (FTD) use. Researchers identified five causal factors that warranted further investigation. The causal factors identified were visual fidelity, procedural similarity, dynamic flight environment, difficulty of task, and visual scanning and response. These causal factors have the potential to affect transfer of training (ToT) from simulated flight …

Capacity Planning Of A Commodity Cluster In An Academic Environment: A Case Study, Linh B. Ngo, Amy W. Apon, Baochuan Lu, Hung Bui, Nathan Hamm, Larry Dowdy, Doug Hoffman, Denny Brewer

Publications

In this paper, the design of a simulation model for evaluating two alternative supercomputer configurations in an academic environment is presented. The workload is analyzed and modeled, and its effect on the relative performance of both systems is studied. The Integrated Capacity Planning Environment (ICPE) toolkit, developed for commodity cluster capacity planning, is successfully applied to the target environment. The ICPE is a tool for workload modeling, simulation modeling, and what-if analysis. A new characterization strategy is applied to the workload to more accurately model commodity cluster work- loads. Through "what-if" analysis, the sensitivity of the baseline system performance to …

A Quantitative Magnetic Resonance Imaging Analysis Of The Cerebellar Deficit Hypothesis Of Dyslexia, Michelle Y. Kibby, Jill B. Fancher, Rochelle Markanen, George W. Hynd

Publications

Recent work by Nicolson and Fawcett suggests the primary source of dysfunction in dyslexia is the cerebellum. In order to examine the cerebellar deficit hypothesis of dyslexia, 20 children with dyslexia (11 had co-morbid ADHD) and 20 without dyslexia (11 had ADHD, 9 were typically developing controls) were assessed with neuropsychological testing and quantitative MRI. Results demonstrated that volumes of both hemispheres and the vermis were not significantly different between groups (ps > .10). However, children without dyslexia demonstrated greater rightward cerebellar hemisphere asymmetry compared to children with dyslexia, F(1,33) = 4.09, p < .05. In addition, children with ADHD only were more comparable to controls in cerebellar asymmetry (none had reversed asymmetry); whereas those with co-morbid dyslexia and ADHD were more comparable to those with dyslexia. The relationship between cerebellar morphology and phonological processing also was assessed. For those without dyslexia, bilateral hemisphere volume moderately correlated with phonological awareness and phonological short-term memory (ps < .05); hemisphere asymmetry moderately correlated with rapid naming errors (p.10), anterior vermis volume was moderately correlated with inattention, hyperactivity and impulsivity (ps < .05) and right hemisphere volume was moderately correlated with inattention and hyperactivity (ps < .05). Overall, our findings provide mixed support for the cerebellar deficit hypothesis of dyslexia. Although cerebellum morphology is atypical in some individuals with dyslexia, cerebellar morphology does not appear to be related to cognitive or motor dysfunction consistently. In our sample, cerebellum morphology may be related to about a third of our cases of dyslexia. Hence, dyslexia may be best accounted for by a combination of cortical and cerebellar contributions.

Selection Of The Spraying Technologies For Over-Coating Of Metal-Stampings With Thermo-Plastics For Use In Direct-Adhesion Polymer Metal Hybrid Load-Bearing Components, M. Grujicic, V. Sellappan, Laine Mears, Norbert Seyr, Andreas Obieglo, Marc Erdmann, Jochen Holzleitner

Publications

The suitability of various polymer-powder spraying technologies for coating of metal-stampings used in polymer metal hybrid (PMH) load-bearing automotive-component applications is considered. The suitability of the spraying technologies is assessed with respect to a need for metal-stamping surface preparation/treatment, their ability to deposit the polymeric material without significant material degradation, the ability to selectively overcoat the metal-stamping, the resulting magnitude of the polymer-to-metal adhesion strength, durability of the polymer/metal bond with respect to prolonged exposure to high-temperature/high-humidity and mechanical/thermal fatigue service conditions, and compatibility with the automotive body-in-white (BIW) manufacturing process chain. The analysis revealed that while each of the …

A New Approach For Nonlinear Finite Element Analysis Of Reinforced Concrete Structures With Corroded Reinforcements, Mohsen A. Shayanfar, Amir Safiey

Publications

A new approach for nonlinear finite element analysis of corroded reinforcements in reinforced concrete (RC) structures is elaborated in the article. An algorithmic procedure for producing the tension-stiffening curve of

RC elements taking into consideration most of effective parameters, e.g.: the rate of steel bar corrosion, bond-slip behavior, concrete cover and amount of reinforcement, is illustrated. This has been established on both experimental and analytical bases. This algorithm is implemented into a nonlinear finite element analysis program. The abilities of the resulted program have been studied by modeling some experimental specimens showing a reasonable agreement between the analytical and experimental …
