Planetary, Lunar and Solar Positions, 601 B.C. to A.D. 1, at Five-Day and Ten Day Intervals

2025/07/31 出版

The need for these tables became pressing when hundreds of astronomical cuneiform tables in the British Museum became available for study, partly through the copies made in the 1880s and 1890s. All these texts originally came from some archive in Babylon which was discovered by Arabs in the middle of the 19th century. Most of the texts were written from about 330 B.C. to the first century A.D. Many of the texts are fragments of the original clay tables which have broken. In many cases, a fragment contains only parts of a few legible lines. Much of the information is of an astronomical character. It is evident that for investigations of these tablets the possibility of rapid scanning of accurately dated planetary positions is of primary importance.

Planetary, Lunar, and Solar Positions, New and Full Moons, A.D. 1650-1805

2025/07/31 出版

These tables cover the period from the mid-17th to the 19th cent. when astronomical ephemerides were evolving most rapidly. These tables resemble those previously pub. by the APS: Tuckerman's "Planetary, Lunar, and Solar Positions, 601 B.C. to A.D. 1" and "A.D. 2 to A.D. 1649" and Goldstine's "New and Full Moon, 1001 B.C. to A.D. 1651." The tables contain features consistent with the almanacs and ephemerides pub. in this period: planetary positions are computed for 12 hours U.T. (noon); and the Julian day number is given for new and full moons. An analytical essay examines the theoretical and computational developments in almanac-making in the period that bridges between Kepler and Laplace.

New and Full Moons, 1001 B.C. to A.D. 1651

2025/07/31 出版

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.

Solving the Planetary CO2 Problem

2025/07/31 出版

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.

An Experimental Determination of the Absolute Oscillator Strengths of the Lines of Two N II Supermultiplets

2025/07/31 出版

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.

Characterization of Neutron-Induced Defects in Isotopically Enriched Lithium Tetraborate

2025/07/31 出版

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.

Vacuum Ultraviolet Absorption Measurements of Atomic Oxygen in a Shock Tube

2025/07/31 出版

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.

Application of KAM Theorem to Earth Orbiting Satellites

2025/07/31 出版

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.

Time Dependent Discrete Ordinates Neutron Transport Using Distribution Iteration in XYZ Geometry

2025/07/31 出版

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.

A Review of Methods Applied by the U.S. Geological Survey in the Assessment of Identified Geothermal Resources

2025/07/31 出版

The U. S. Geological Survey (USGS) is conducting an updated assessment of geothermal resources in the United States. The primary method applied in assessments of identified geothermal systems by the USGS and other organizations is the volume method, in which the recoverable heat is estimated from the thermal energy available in a reservoir. An important focus in the assessment project is on the development of geothermal resource models consistent with the production histories and observed characteristics of exploited geothermal fields. The new assessment will incorporate some changes in the models for temperature and depth ranges for electric power production, preferred chemical geothermometers for estimates of reservoir temperatures, estimates of reservoir volumes, and geothermal energy recovery factors. Monte Carlo simulations are used to characterize uncertainties in the estimates of electric power generation. These new models for the recovery of heat from heterogeneous, fractured reservoirs provide a physically realistic basis for evaluating the production potential of natural geothermal reservoirs.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.
