Design outline for a new multiman ATC simulation facility at NASA-Ames Research Center

A new and unique facility for studying human factors aspects in aeronautics is being planned for use in the Man-Vehicle Systems Research Division at the NASA-Ames Research Center. This facility will replace the existing three cockpit-single ground controller station and be expandable to include approximately seven cockpits and two ground controller stations. Unlike the previous system, each cockpit will be mini-computer centered and linked to a main CPU to effect a distributed computation facility. Each simulator will compute its own flight dynamic and flight path predictor. Mechanical flight instruments in each cockpit will be locally supported and CRT cockpit displays of (e.g.) traffic and or RNAV information will be centrally computed and distributed as a means of extending the existing computational and graphical resources. An outline of the total design is presented which addresses the technical design options and research possibilities of this unique man-machine facility and which may also serve as a model for other real time distributed simulation facilities

Young Germans in the World: Race, Gender, and Imperialism in Wilhelmine Young Adult Literature

This dissertation shows how popular reading material for young adults was used to craft a new generation of German imperial citizens in the Second Empire (1871-1918). Uniting insights from contemporary postcolonial theory, gender studies, and the global history of nineteenth- and twentieth-century Germany, it shows the intersectional development of German national identity in the children’s and young adult literature of Wilhelmine Germany. As literature written by adults for young people, designed both to entertain and instruct, children’s and young adult literature offers a unique window on how Germany built nation and empire simultaneously during this period. Focusing on texts set outside of the European borders of Germany by authors such as Else Ury, Sophie Wörishöffer, Karl May, Friedrich Pajeken, Bertha Clément, Brigitte Augusti, and Carl Falkenhorst, it shows how German literature carves a space for Germans outside of Germany to settle in the Americas, colonize Africa, and travel from the peripheries to the metropole and back again, and how Germany’s understanding of its place in the world undergoes a dramatic shift in light of the outbreak of the World War in 1914. German young adult literature from this period offers a portrait of German identity as both racial and cultural and shows German heroes and heroines as racially superior to indigenous people and culturally superior to other immigrant groups or colonizers. Narrative literature for young people from this time features young heroes and heroines who come of age abroad—boys who learn how to be men in Africa, South America, or the Wild West and girls who grow to maturity and marriage in various colonial settings—and reveals how metropolitan authors conceived of the nature of German identity in a period of globalization and colonization

A modified method of total elemental analysis for determining background metals in Tennessee

In order to assess the impact of metal pollution, a knowledge of indigenous metal levels is required. Data for background metal concentrations for soils and parent materials in Tennessee are not available in scientific literature. The objective of this study was to establish background metal concentrations on the major physiographic regions or Major Land Resource Areas (MLRAs) of Tennessee. Background metal concentration information will serve as a future reference for interpreting metal data. To meet this objective, it was necessary to test and evaluate an acid digestion procedure using a microwave oven for preparing soil samples for total analysis. An acid digestion procedure for total elemental analysis was evaluated on soils of different textures to establish background metal concentrations. Samples were dissolved in 5 ml of aqua-regia and 2 ml of hydrofluoric acid (HCI-HNO3-HF). Samples were heated in a microwave oven to facilitate reactions. Boric acid (1 gm) was then added to neutralize the hydrofluoric acid. The solutions were transferred to 100 ml volumetrics and brought to volume for analysis. The elements: Al, Ca, Fe, K, Mg, Na, P, S, Si, and Ti, were analyzed by inductively coupled argon plasma atomic emission spectrometer (ICAPAES). Recovery rates were established by analysis of a coal fly ash standard (National Bureau of Standards). Recovery rates ranged from 88.9 percent for Fe to 101 percent for Si and Na. The procedure was tested over a broad range of textures using deep core samples. These samples were of loess, alluvium, and Tertiary Sand parent materials from the University of Tennessee Ames Plantation in Southwest Tennessee. A modification for sandy textured samples involved overnight digestion in hydrofluoric acid to achieve total dissolution. This digestion procedure was applied to samples from thirteen selected pedons from six of the eight MLRAs in Tennessee. Total analysis for twenty-three elements (Al, As, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Mo, Na, Ni, P, Pb, S, Si, Sr, Ti, Zn, Zr) were then completed on these samples using ICAPAES. Generally, metal concentrations, in all regions of the state, were within the established ranges for average elemental concentrations in soils and crustal rocks

Advanced multilateration theory, software development, and data processing: The MICRODOT system

The process of geometric parameter estimation to accuracies of one centimeter, i.e., multilateration, is defined and applications are listed. A brief functional explanation of the theory is presented. Next, various multilateration systems are described in order of increasing system complexity. Expected systems accuracy is discussed from a general point of view and a summary of the errors is listed. An outline of the design of a software processing system for multilateration, called MICRODOT, is presented next. The links of this software, which can be used for multilateration data simulations or operational data reduction, are examined on an individual basis. Functional flow diagrams are presented to aid in understanding the software capability. MICRODOT capability is described with respect to vehicle configurations, interstation coordinate reduction, geophysical parameter estimation, and orbit determination. Numerical results obtained from MICRODOT via data simulations are displayed both for hypothetical and real world vehicle/station configurations such as used in the GEOS-3 Project. These simulations show the inherent power of the multilateration procedure

Performance of Major Flare Watches from the Max Millennium Program (2001-2010)

The physical processes that trigger solar flares are not well understood and significant debate remains around processes governing particle acceleration, energy partition, and particle and energy transport. Observations at high resolution in energy, time, and space are required in multiple energy ranges over the whole course of many flares in order to build an understanding of these processes. Obtaining high-quality, co-temporal data from ground- and space- based instruments is crucial to achieving this goal and was the primary motivation for starting the Max Millennium program and Major Flare Watch (MFW) alerts, aimed at coordinating observations of all flares >X1 GOES X-ray classification (including those partially occulted by the limb). We present a review of the performance of MFWs from 1 February 2001 to 31 May 2010, inclusive, that finds: (1) 220 MFWs were issued in 3,407 days considered (6.5% duty cycle), with these occurring in 32 uninterrupted periods that typically last 2-8 days; (2) 56% of flares >X1 were caught, occurring in 19% of MFW days; (3) MFW periods ended at suitable times, but substantial gain could have been achieved in percentage of flares caught if periods had started 24 h earlier; (4) MFWs successfully forecast X-class flares with a true skill statistic (TSS) verification metric score of 0.500, that is comparable to a categorical flare/no-flare interpretation of the NOAA Space Weather Prediction Centre probabilistic forecasts (TSS = 0.488).Comment: 19 pages, 2 figures, accepted for publication in Solar Physic

Collective quantum jumps of Rydberg atoms

We study an open quantum system of atoms with long-range Rydberg interaction, laser driving, and spontaneous emission. Over time, the system occasionally jumps between a state of low Rydberg population and a state of high Rydberg population. The jumps are inherently collective and in fact exist only for a large number of atoms. We explain how entanglement and quantum measurement enable the jumps, which are otherwise classically forbidden.Comment: 4 page

A universal ionization threshold for strongly driven Rydberg states

We observe a universal ionization threshold for microwave driven one-electron Rydberg states of H, Li, Na, and Rb, in an {\em ab initio} numerical treatment without adjustable parameters. This sheds new light on old experimental data, and widens the scene for Anderson localization in light matter interaction.Comment: 4 pages, 1 figur
