Planetary, Lunar, and Solar Positions, A.D. 2 to A.D. 1649, at Five-Day and Ten-Day Intervals
These tables for A.D. 2 to A.D. 1649 are an extension, with some improvements, of earlier ones for 601 B.C. to A.D. 1. As before, they give the geocentric positions (tropic celestial longitudes & latitudes, i.e. with respect to the mean equinox of date), in units of 0 degrees.01 for the Sun & planets, & 0 degrees.1 for the Moon, at 16h Universal Time - 4 P.M. Greenwich Civil Time - 7 P.M. local mean time of 45 degrees East longitude (Babylon), on the indicated dates, all in the Julian calendar, hence for Julian dates 5n + 1/6 for the Moon, Mercury, & Venus, & 1-n + 1/6 for the Sun, Mars, Jupiter, & Saturn. The same adaptation of the theories of Leverrier, Gaillot, & Hansen, with modified elements by Schoch, was used as before, except as noted below. The chief change has been to improve the positions of Jupiter & Saturn. Tables.
Characterization of Neutron-Induced Defects in Isotopically Enriched Lithium Tetraborate
Lithium Tetraborate (LTB) is assessed for use as a material for neutron detection. LTB isotopically enriched in either Li-6 or B-10 provides a medium that efficiently captures and transmutes neutrons into more readily detected forms of material or energy. Neutron detection is desirable to detect elicit movement of special nuclear material or nuclear weapons. Single crystals of LTB, Li-6 or B-10 enriched, were neutron irradiated, and electron paramagnetic resonance was used to detect point defects induced by the neutrons. Multiple defects were noted in the irradiated crystals. Two particular defects, perturbed lithium vacancies and lithium clusters are proposed as induced by thermal neutrons. Parallel experiments on silver doped LTB indicated that fast neutrons induce interstitial defects including interstitial oxygen, lithium, and silver atoms in silver doped crystals. Electron paramagnetic resonance, electron-nuclear double resonance, pulsed anneal, and thermo luminescence studies prior to neutron irradiation concluded that silver doped LTB crystals contain silver point defects that trap both electrons and holes. Pulsed anneal and thermo luminescence studies of all crystal types prior to neutron irradiation suggest neutron induced defects are significantly more stable that as grown defects.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

An Experimental Determination of the Absolute Oscillator Strengths of the Lines of Two N II Supermultiplets
The following work describes the experimental determination of the absolute oscillator strengths of several N II-lines. The light source was the plasma of a wall-stabilized enclosed [cylindrical] arc in pure nitrogen. The parameters of this plasma near the axis of the arc were calculated from the measured total intensity of the hydrogen-like triplet-multiplet of the series 2p3d-2p4f. It was here assumed that the oscillator strengths of this multiplet can be calculated by the Bates and Damgaard Coulomb field approximation. In addition, an attempt was made to check the measured oscillator strengths of the N II line in the nitrogen plasma by measurements in a helium-nitrogen mixture, using the known oscillator strengths of helium.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

New and Full Moons, 1001 B.C. to A.D. 1651
Originally pub. in 1973; reprinted in 1994. Presents tables giving the dates of all new and full moons during an historical era when these data were of considerable interest and importance. The longitudes of the moon at each of these times is also given, as is a consecutive enumeration of the conjunctions and a similar one of the oppositions. All dates are reckoned in the Julian calendar. These dates and times are calculated for an observer in Babylon, or equivalently Baghdad, since this location is fairly centrally located for the historians of the period. The time used is civil time and is based on a 24-hour clock with its origin at midnight. Since this vol. may be considered as a suppl. to Tuckerman's tables, all fundamental astronomical elements have been taken from them.

Vacuum Ultraviolet Absorption Measurements of Atomic Oxygen in a Shock Tube
The absorption of vacuum ultraviolet light by atomic oxygen has been measured in the Electric Arc-driven Shock Tube (EAST) Facility at NASA-Ames Research Center. This investigation demonstrates the instrumentation required to determine atomic oxygen concentrations from absorption measurements in impulse facilities. A shock wave dissociates molecular oxygen, producing a high temperature sample of atomic oxygen in the shock tube. A probe beam is generated with a Raman-shifted ArF excimer laser. By suitable tuning of the laser, absorption is measured over a range of wavelengths in the region of the atomic line at 130.49 nm. The line shape function is determined from measurements at atomic oxygen densities of 3x10(exp 17) and 9x10(exp 17) cm(exp -3). The broadening coefficient for resonance interactions is deduced from this data, and this value is in accord with available theoretical models.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Survey of Islamic Astronomical Tables
The source material for the study of medieval oriental astronomy consists of Byzantine Greek, Sanscrit, Hebrew, Arabic, Persian, and Turkish astronomical and astrological manuscripts. If one desires to build up a detailed picture of Islamic astronomy, one can choose material from these available manuscripts. Of these manuscripts it is possible to isolate a group of works, the "zijes". A "zij" consists of the numerical tables and accompanying explanation sufficient to measure time and to compute planetary and stellar positions, appearance, and eclipses. This paper is a survey of the number, distribution, contents, and relations between "zijes" written in Arabic or Persian during the period from the 8th through the 15th centuries. Illustrations.

Time Dependent Discrete Ordinates Neutron Transport Using Distribution Iteration in XYZ Geometry
The DI algorithm is an alternative to source iteration that, in our testing, does not require an accelerator. I developed a formal verification plan and executed it to verify the results produced by my code that implemented DI with the above features. A new, matrix albedo, boundary condition treatment was developed and implemented so that infinite-medium benchmarks could be included in the verification test suite. The DI algorithm was modified for parallel efficiency and the prior instability of the refinement sweep was corrected. The testing revealed that DI performed as well or faster than source iteration with DSA and that DI continued to work where DSA failed. Performance did degrade when the diamond-difference (without fixup) spatial quadrature was used. Because diamond-difference is a non-positive spatial quadrature, it can produce nonphysical negative fluxes, particularly in higher dimensions. I developed a new fixup scheme to accommodate the negative fluxes, but it did not improve performance in XYZ geometry when the scattering ratio was near unity.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Solving the Planetary CO2 Problem
In this book, we highlight key dogmatic beliefs in mainstream physics that contradict well-established experimental results. Grounded in these facts, we reveal that a unification will come to electromagnetism, gravitation, and inertia after realizing that they are all phenomena of the same material fluid (not of the molecular matter but of the finer field-matter). This leads to a corrected, nonlinear, non-Maxwellian form of electromagnetism, unified with a non-Einsteinian approach to gravitation and inertia. The classical theories of Maxwell, of Newton, and even of Einstein's special relativity emerge as special cases or approximations after the true Navier-Stokes non-linear equations of the fieldmatter fluid. We also present the prediction that solar energy is continuously stored in the gravitational field and can be harnessed using methods similar to Nikola Tesla's inventions-technologies that remain largely misunderstood in academic physics. This approach opens a path to solving the CO₂ problem through access to constant, low-cost solar energy. It also suggests the potential for new electromagnetic propulsion systems, reminiscent of the alleged flying discs.

Application of KAM Theorem to Earth Orbiting Satellites
An orbit that lies on a Kolmogorov, Arnold, and Moser (KAM) Torus will remain on that torus until and unless it experiences a force that causes it to leave the torus. Earth satellites that are subject only to the Earth's gravity field may lie on such KAM tori. Analyzing on orbit satellite position data should allow for the identification of the fundamental frequencies needed to define the KAM tori for modeling Earth satellite orbits. KAM Tori are created for the Gravity Recovery and Climate Experience (GRACE) and Jason-1 satellites to model their orbital motion. Precise position data for the satellites is analyzed using a modified Laskar frequency algorithm to determine the fundamental frequencies of the orbits. The fundamental frequencies along with a set of Fourier coefficients completely describe the tori. These tori are then compared to the precise orbital position data for the satellites to determine how well they model the orbits. The KAM torus created for the Jason-1 satellite is able to represent the position of the satellites to within 1 km.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Theoretical Issues on Systems Science
In "Theoretical Issues on Systems Science", we present theoretical issues including theoretical incompleteness, multiplicity, systems as networks and chaos, game theory, and meta-structures. Other less explored research topics include equivalence and tolerance in systems, pending systems, recurrence and self-reflexivity, remote synchronization, and the significance of using complex numbers in system models.The first group of papers addresses theoretical aspects, including 1) the role of noise in complex systems; 2) the potential of general systems theory to serve as a theory of everything; 3) the drawbacks of applying classical axiomatic deductive mathematical approaches to topics such as control evolution by rewriting DNA "instructions"; 4) the near non-existence of purely "theory-free" approaches and the balance between theoretical and empirical contributions; 5) the neglect in reductionism in that systems acquire properties and the assumption that multiple, variable interactions of complexity can be analytically "zipped"; and 6) tree-based methods for statistical learning, for which the author presents a systems theory-based framework to speed up discrete event system stochastic simulations.The second group of papers examines theoretical aspects within specific fields, including 1) human dynamics; 2) human cognition; 3) complex physiological processes; 4) medicine; 5) chemical organization theory; and 6) psychotherapy.

Time Dependent Discrete Ordinates Neutron Transport Using Distribution Iteration in XYZ Geometry
The DI algorithm is an alternative to source iteration that, in our testing, does not require an accelerator. I developed a formal verification plan and executed it to verify the results produced by my code that implemented DI with the above features. A new, matrix albedo, boundary condition treatment was developed and implemented so that infinite-medium benchmarks could be included in the verification test suite. The DI algorithm was modified for parallel efficiency and the prior instability of the refinement sweep was corrected. The testing revealed that DI performed as well or faster than source iteration with DSA and that DI continued to work where DSA failed. Performance did degrade when the diamond-difference (without fixup) spatial quadrature was used. Because diamond-difference is a non-positive spatial quadrature, it can produce nonphysical negative fluxes, particularly in higher dimensions. I developed a new fixup scheme to accommodate the negative fluxes, but it did not improve performance in XYZ geometry when the scattering ratio was near unity.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

An Investigation of Shock Wave Physics via Hybrid CFD-BGK Solution Methods for Nonequilibrium Flows
The Unified Flow Solver, a hybrid continuum-rarefied code, is used to investigate the internal structure of a normal shock wave for a Mach range of 1.55 to 9.0 for Argon, and 1.53 to 3.8 for diatomic Nitrogen. Reciprocal shock thickness, density, temperature, heat flux, and the velocity distribution function are calculated for a one-dimensional shock wave and compared with experimental data from Alsmeyer and DSMC results from Bird. Using the Euler, Navier-Stokes, BGK model, and Three-Temperature BGK model schemes, results from UFS compare well with experiment and DSMC. The Euler scheme shows atypical results, possibly resulting from modifications made to include internal energies. An entropy spot is introduced into a two-dimensional domain to investigate entropy-shock interactions over a range of Knudsen numbers (Kn=0.01, 0.1, and 1.0) for Mach 2.0 in Argon. Previous work on entropy-shock interactions has only been performed using an Euler scheme. Here, results are presented in Argon using coupled BGK and Navier-Stokes solvers. Density, pressure, and temperature profiles, as well as the profiles of their gradients, are reported at certain times after the entropy spot convects through the shock.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.
