Improved Collision Modeling for Direct Simulation Monte Carlo Methods
In the Smoothed Accept/Reject (SAR) algorithm, the accept/reject criteria is altered from Direct Simulation Monte Carlo (DSMC): rather than a binary function of rejection or acceptance, collisions can be partially accepted with a linear weighting between zero and one. The partial acceptance is based on a band around the original accept/reject criteria defined as a percentage of the collision criteria, which is called . A relationship previously noted between Mach and is explored. Velocity distributions of the particles are examined for all algorithms and compared to experimental data to determine the effect of the SAR algorithm at a microscopic level. All of the comparisons to experiment show a Mach dependency that has previously been noted, and the dependency was defined for the normal shock simulations. DSMC does adequately simulate the nonequilibrium within the cells at a high Mach number through the shock, but SAR does. The SAR algorithm models the flowfield in the shock better than DSMC through a change in the collision rate and particle sampling methods, which allows for a more accurate simulation.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Diffusion of Rubidium Vapor Through Hollow-Core Fibers for Gas-Phase Fiber Lasers
This work examines the diffusion of rubidium through a small diameter tube alone and in the presence of noble gases. A fluid dynamics analysis is investigated to aid in choosing a method for transferring atomic rubidium vapor that is reliable and efficient. Solutions to the time dependant ordinary differential equation describing the experimental flow properties of the system reveal more precise outcomes than previously practiced routines. Resolved viscosities and Poiseuille flow theory velocity profile distributions are characterized for noble gas carriers of the rubidium vapor. Applying Reynolds Numbers to the flow experiments provides pressure differential boundaries that are employed in the successful rubidium vapor transfer process. Atomic spectroscopy is demonstrated through the use of a rubidium D1 resonate diode laser to record an absorption spectrum and extract alkali vapor densities that successfully propagated through a 12 cm long capillary tube with a 500 ?m inner diameter.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Efficient and Accurate Computation of Non-Negative Anisotropic Group Scattering Cross Sections for Discrete Ordinates and Monte Carlo Radiaton Transport
A new method for approximating anisotropic, multi-group scatter cross sections for use in discretized and Monte Carlo multi-group neutron transport is presented. The new method eliminates unphysical artifacts such as negative group scatter cross sections and falsely positive cross sections. Additionally, when combined with the discrete elements angular quadrature method, the new cross sections eliminate the lack of angular support in the discrete ordinates quadrature method. The new method generates piecewise-average group-to-group scatter cross sections. The accuracy and efficiency for calculating the discrete elements cross sections has improved by many orders of magnitude compared to DelGrande and Mathews (7) previous implementation. The new cross sections have extended the discrete elements method to all neutron-producing representations in the Evaluated Nuclear Data Files (13). The new cross section method has been validated and tested with the cross section generation code, NJOY (13). Results of transport calculations using discrete elements, discrete ordinates, and Monte Carlo methods for two, one-dimensional slab geometry problems are compared.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Planetary Defense
Concern exists among an increasing number of scientists throughout the world regarding the possibility of a catastrophic event caused by an impact of a large Earth-crossing object (ECO) on the Earth-Moon System (EMS), be it an asteroid or comet. Such events, although rare for large objects (greater than 1 km diameter), are not unprecedented. Indeed, the great upheaval and resulting ice age that marked the extinction of the dinosaurs is thought to have been caused by the impact of a 10 km diameter asteroid. Such an event is thought to occur approximately every millennia. In 1908 a stony asteroid of approximately 50 meters diameter exploded in the air above the Tunguska River in Siberia, producing an equivalent yield of 15-30 megatons (mt) of TNT, leveling over 2000 square miles of dense forest. Such an event is thought to occur approximately every century.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Daytime Detection of Space Objects
Space Situational Awareness (SSA) requires repeated object updates for orbit accuracy. Detection of unknown objects is critical. A daytime model was developed that evaluated sun flares and assessed thermal emissions from space objects. Iridium satellites generate predictable sun glints. These were used as a model baseline for daytime detections. Flares and space object thermal emissions were examined for daytime detection. A variety of geometric, material and atmospheric characteristics affected this daytime detection capability. In a photon noise limited mode, simulated Iridium flares were detected. The peak Signalto- Noise Ratios (SNR) were 6.05e18, 9.63e5, and 1.65e7 for the nighttime, daytime and infrared flares respectively. The thermal emission of space objects at 353K, 900K and 1300K with 2 to 20 m2 emitting areas were evaluated. The peak emission was for the 20 m2 900K object with an SNR of 1.08e10.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Neutron Detection Utilizing Gadolinium Doped Hafnium Oxide Films
Gadolinium (Gd) doped hafnium oxide (HfO2) was deposited onto a silicon substrate using pulsed laser deposition. Synchrotron radiation was used to perform Gd L3-edge extended X-ray absorption fine structure (EXAFS) measurements on 3%, 10%, and 15% doped HfO2 samples. The interatomic distances determined from Fourier transformation and fitting the data show Gd occupying the hafnium site in the HfO2 lattice, there was no clustering of Gd atoms, and the Gd ion retains monoclinic local symmetery for all levels of doping. Current as a function of voltage experiments identified the films as having poor diode characteristics with high leakage current in the forward bias region. However, a proper bias (0.5 V) for the purpose of neutron detection was identified and applied across the diodes. Using a high, non-varying neutron flux in a nuclear reactor, Gd doped HfO2 was able to be used in a detection system and displayed the ability to detect neutrons.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Distribution Iteration
The discrete ordinates method is widely used to solve the Boltzmann transport equation for neutral particle transport for many engineering applications. Source iteration is used to solve the discrete ordinates system of equations, but can be slow to converge in highly scattering problems. Synthetic acceleration techniques have been developed to address this shortcoming; however, recent research has shown synthetic acceleration to lose effectiveness or diverge for certain problems. LTC Wager introduced an alternative to source iteration and demonstrated it in slab geometry. Here the method is further developed, enhancing efficiency in various ways, and demonstrated in XY-geometry as well as slab geometry. It is shown to be efficient even for those problems for which diffusion-synthetic and transport-synthetic accelerations fail or are ineffective. The method has significant advantages for massively-parallel implementations.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Nuclear Weapon Yield Determination Through Nano Indentation of Thermally Degraded Automobile Paint
This work investigated the suitability of automotive clearcoat as a nuclear weapon yield sensor, using the change in elastic modulus as the primary metric. The AFIT Xenon Thermal Simulator (AXTS) was used to simulate a nuclear thermal pulse. The elastic modulus of the clearcoat was measured using a nano indenter. During this research the power density of the AXTS beam was increased from 44.7 to 63.7 W/cm2. The morphological steps through which automobile paint proceeds as it thermally degrades were identified and correlated with temperatures. A computer model was created and used to ensure that the paint's time-temperature response to the AXTS pulse was comparable to that of a replicate nuclear thermal pulse. Clearcoat's physical properties exhibit a low sensitivity to incident thermal energy. Variability among these properties remains essentially unchanged by exposure to the thermal pulse. A weak correlation between change in elastic modulus and exposure time was identified. A similarly weak correlation between exposure time and each of load on sample, harmonic stiffness, and hardness was also identified. It was concluded that these correlation were too weak to be used for post-detonation forensics.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Numerical Solutions to the Two Dimensional Boltzmann Equation
A strict kinetic, two-dimensional model of the electron kinetics within a glow discharge positive column is developed. The problem is solved in cylindrical geometry using the standard two-term Legendre expansion of the electron velocity distribution function. The model establishes a steady state solution, such that the net ionization rate is exactly balanced by the wall loss. In addition to a thorough analytic development, we present the numerical techniques used to solve the resulting elliptic partial differential equation, including an efficient method to treat sparse banded matrices. The model is validated against published results, local and nonlocal kinetic approximations, and a previous Monte Carlo treatment. Having created a working model, we conduct an investigation into current flow within the solution area of a neon column, made possible by this 2-D treatment. Furthermore, we investigate the range of applicability of the earlier local and nonlocal kinetic approximations and finally present a short discussion on the effect different forms of wall loss have on the overall distribution function.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Investigation of YAG
The properties of thin, cerium activated, yttrium aluminum garnet (YAG: Ce), scintillating fiber-shaped crystals were investigated for particle tracking and calorimetric applications such as Compton imaging of Special Nuclear Material from remote platforms at standoff ranges. Silicon photomultipliers (SiPMs) are relatively new, efficient, single photon sensitive, solid-state photodiode arrays which are well suited for the readout of scintillating fibers. Using SiPMs, the scintillation decay time profiles of six 400 m YAG: Ce fiber crystals were measured under alpha and gamma irradiation. Interestingly, the observed decay times in the thin fibers were substantially slower than values for bulk single crystal YAG: Ce reported in open scientific literature; possible explanations are explored. Both laser induced photoluminescence and alpha scintillation measurements were conducted to estimate the effective attenuation length of the YAG: Ce fibers. Using the measured attenuation lengths, position-of-interaction measurements were conducted to determine the achievable position resolution in YAG: Ce fibers using dual fiber end SiPM readouts. The measured results are compared to theoretical calculations and Monte Carlo simulations. Finally, improvements to the detector concept, including a formula to determine the best SiPM model based on device parameters and the Birks' figure of merit of the scintillating material, are presented.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Multi-Dimensional Wave Front Sensing Algorithms for Embedded Tracking and Adaptive Optics Applications
Current tracking and adaptive optics techniques cannot compensate for fastmoving extended objects, which is important for ground-based telescopes providing space situational awareness. To fill this need, a vector-projection maximum-likelihood wave-front sensing algorithm development and testing follows for this application. A derivation and simplification of the Cramer-Rao Lower Bound for wave-front sensing using a laser guide star bounds the performance of these systems and guides implementation of a vastly optimized maximum-likelihood search algorithm. A complete analysis of the bias, mean square error, and variance of the algorithm demonstrates exceptional performance of the new sensor. A proof of concept implementation shows feasibility of deployment in modern adaptive optics systems. The vector-projection maximum-likelihood sensor satisfies the need for tracking and wave-front sensing of extended objects using current adaptive optics hardware designs.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Quantitative Object Reconstruction Using Abel Transform Tomography and Mixed Variable Optimization
Researchers at the Los Alamos National Laboratory (LANL) are interested in quantitatively reconstructing an object using Abel transform x-ray tomography. Specifically, they obtain a radiograph by x-raying an object and attempt to quantitatively determine the number and types of materials and the thicknesses of each material layer. Their current methodologies either fail to provide a quantitative description of the object or are generally too slow to be useful in practice. As an alternative, the problem is modeled here as a mixed variable programming (MVP) problem, in which some variables are nonnumeric and for which no derivative information is available. The generalized pattern search (GPS) algorithm for linearly constrained MVP problems is applied to the x-ray tomography problem, by means of the NOMADm MATLABr software package. Numerical results are provided for several test configurations of cylindrically symmetrical objects and show that, while there are difficulties to be overcome by researchers at LANL, this method is promising for solving x-ray tomography object reconstruction problems in practice.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

The Lnt Report
The LNT Report: How the linear no-threshold model of radiation safety made the world afraid of nuclear power. This book is a fascinating detective story, uncovering the bad faith, muddled thinking, and ideological prejudice that led to a false and injurious conclusion: nuclear radiation is risky in any dosage, no matter how low. The truth, finally made clear by many years of careful scientific criticism, is that low doses of radiation are harmless, and even beneficial to health, because of the human body's natural ability to repair cells damaged by radiation. It follows that fears of the risks of nuclear power have been wildly exaggerated and then irresponsibly hyped. Nuclear energy is not only clean and inexhaustible, its risks are far smaller than the hazards of any alternative--including not just fossil fuels but also 'renewables', solar and wind, which turn out to be far more dangerous than people have been led to believe. While radiation can indeed be dangerous at high levels, the issue has been blown out of proportion by an unsupported--and now known to be provably wrong--model of nuclear risk assessment called Linear No-Threshold or LNT. LNT was first presented to the world by Hermann Muller in 1946, when nuclear technology was in its infancy. LNT holds that "There is no safe dose of radiation, and all doses are cumulative." Both assertions are now known to be false.Beginning with Muller's careless assumptions, The LNT Report traces the twists and turns of LNT's reception and dissemination by politicians, media, and the public. The propagation of LNT was boosted by some people's horror at the prospect of nuclear war, leading them to say anything to discredit nuclear energy, and also by fossil fuel interests, which had their own anti-nuclear bias.The LNT Report has been exhaustively vetted and approved by numerous scientific experts, whose names and credentials are listed in the book. This is solid science at its best, explained to the non-scientist reader by a brilliant professional writer. It's a companion book to Earth Is a Nuclear Planet (2024) by the same author.
