Mechanical Stability Of Body-Centered Cubic Iron At Earth\u27s Core Pressure And Temperature Conditions Using A Molecular Graph Kernel Regression And Gaussian Process.
No full textWe used machine learning to study nonmagnetic BCC iron in conditions similar to thosefound in the Earthâ??s core. Our model predicts the stability of BCC iron at high temperatures and pressures by analyzing a dataset from ab initio molecular dynamics simulations. The framework uses Gaussian process regression to make predictions by comparing the similarity between molecules. This comparison is made using the marginalized graph kernel. To use the marginalized graph kernel, the framework applies a spatial adjacency rule to convert molecules into graphs, where the vertices and edges are labeled by elements and interatomic distances, respectively. We can use this model to forecast energy landscapes, identify the forces acting on iron atoms and recognize any instability pathways. Our findings suggest that BCC iron is stable in such extreme environments. This machine learning approach helps us better understand material behavior in challenging experimental settings, which is valuable for geophysical and materials science applications
Geotechnical Aspects of Extraterrestrial Regolith Simulants
No full textGeotechnical engineering has been crucial to the success of construction projects on Earth, and now it is time to extend this expertise to other celestial bodies. As NASA planned the Apollo missions, geotechnical engineers conducted extensive studies to understand the properties of lunar soil, using analogs like volcanic ash and other terrestrial materials to simulate the moon\u27s surface. Nevertheless, it was not until the inception of the year 1968 that the Surveyor landers were able to give the first actual estimates of the moon soil geotechnical characteristics such as bearing capacity, void ratio, etc. With the development of more refined regolith simulants based on samples returned from the Apollo 11 Mission in 1969, geotechnical engineers managed to assess further and more complex varieties of properties indoors in earthbound laboratories.
The objective of this doctoral work is to mechanistically characterize the physical and mechanical properties of twelve lunar and one Martian regolith simulant provided by NASA. In order to do so, a comprehensive experimental program was designed to mimic unbound granular material compacted states behavior in the laboratory. The focus was on determining the resilient properties, strength parameters, and deformation potential of these materials. Different from prior studies, this dissertation undertook a large set of interrelated geotechnical tests demonstrating significant variability based on factors such as load application rates and magnitudes, density state, and compaction methods.
The experimental work demonstrated the existence of the noticeable strain rate dependency on the strength parameters for the simulants tested at various relative compaction levels. Further, it was found that the strength degradation was also greatly dependent on breakage of these simulantsâ?? particles. This underscores the importance of nonlinear and anisotropic regolith modeling for accurately determining orthogonal strength characteristics, settlement potential, and the stability of platforms for planetary construction. These results are of high relevance to lunar and Martian missions and infrastructure expansion since they equip engineers with knowledge of how to build structures that will survive the moon and mars conditions thereby promoting safety and sustainability of future missions.
Finally, a series of numerical analyses employing finite and discrete element methods were performed to model the behavior of lunar and Martian surfaces subjected to dynamic loading from planetary rovers. The main aim of these simulation series was to predict dust emission and to characterize the anisotropic nature of the surface regolith using the geotechnical properties tested in the laboratory as input parameters
General Purpose GPU Benchmarks for Neural Networks
No full textNeural networks are a field of computing experiencing a rise in popularity in recent years due to the utilization of graphics processing units as their computational centerpiece. The lack of neural network benchmarks for the open-source Nyuzi architecture, a developing general-purpose processor with graphical processing capabilities, is the focus of this thesis. This work aims to determine whether Nyuziâ??s performance counters and traceable events suffice for performance tuning of neural network implementations. Given the mathematical intensity of neural networks, a strong emphasis is placed on events related to arithmetic instructions. Experimenting with neural network implementations in C and C++, existent functionality resulted sparse. Modification of performance counters allowed the observation that object-oriented implementations of a small neural network yield an order of magnitude improvement in execution time of arithmetic instructions when compared to a procedural implementation. Results suggest a need to expand Nyuziâ??s number of performance counters and diversity of traceable events to boost the development of efficient neural network applications
Vertically Aligned Nickel Cobalt Molybdenum Copper oxide Nanotubes for High performance Asymmetric Supercapacitors
No full textDesigning materials having novel multi metal oxide electrodes with controlled structure and composition is a critical technological challenge for high performance supercapacitor applications. Quaternary metal oxides have attracted considerable attention in this field, where many methods have been used to improve their performance. In the present work, the nickel cobalt molybdenum copper oxide (NCMCuO2) has been synthesized using a hydrothermal method. The effect of different concentrations of Cu doping (0.5%,1.0% and 2.0%) on the NCM frame and structural and electrochemical properties of the quaternary metal oxide (NCMCuO2) are studied thoroughly. The XRD pattern of synthesized NCMCuO2 exhibited predominant (002) orientation confirms the successful formation of NCMCuO2 phase with an average crystallite size of 30 nm. NCMCu1.0O2 demonstrates vertically aligned nano tubes with an average tube size of 90 nm and a length of 3 µm are observed from both FESEM and TEM analyses. With unique morphology of the vertical aligned nanotubes, the NCMCu1.0O2 contains reliable 3D-conductive channels that help rapid transport throughout the electrode as well as synergistic effects. The BET analyses reveal that the NCMCu0.1O2 provides a high surface area of 42.71 m2g-1 and high mesoporosity with nanotube morphology. The XPS analysis reveals that all Ni, Co, Mo, Cu and O elements existence and maintain their chemical homogeneity in NCMCu1.0O2. Chemical-composition tuning, and optimization yields NCMCu1.0O2 to deliver the superior specific capacitance of 2510 Fg-1 at 1 Ag-1 and retain ~95% capacitance after 5000 cycles. The NCMCu1.0O2//AC asymmetric supercapacitor (ASC) device demonstrates excellent energy density and power density values of 110.93 Wh kg-1 and 1279.84 W kg-1, respectively. The breakthrough stems from the deliberate incorporation of multiple metal oxides, meticulously tailored in their compositions. Such an approach heralds a paradigm shift in the quest for superior energy storage solutions, paving the way for transformative developments in the realm of high-performance energy storage devices
Thermal Anharmonicity Of Transition Metals: A Case Study Of Tantalum
No full textDensity functional theory (DFT) is commonly used for evaluating the thermal propertiesand equation of state of solids, usually within the quasi-harmonic approximation (QHA). In transition metals, thermodynamic quantities such as the thermal pressure and Gruneisen parameter are poorly reproduced compared with experimental values or with direct computational methods like quantum-molecular dynamics (QMD) simulations. Surprisingly, there has not been to date, a systematic study aimed at understanding the reasons for these discrepancies. Using Tantalum as a case study, we have evaluated the temperature dependence of the phonon frequencies employing Harmonic Ensemble Lattice Dynamics (HELD) combined with classical and quantum molecular dynamics. Our results show that phonon frequencies in tantalum are highly temperature-dependent and effective anharmonic effects, lead to significant softening in the transverse acoustic modes, which in turn leads to significant lowering in the calculated values of the Gruneisen parameter, even at room temperature. Our calculations align well with experimental observations and previous studies, confirming the importance of incorporating temperature effects for accurately predicting the thermal properties and equation of state of Tantalum

Road Work
No full textThis thesis explores the intricate interplay between addiction and creativity through the lens of standup comedy, an art form notorious for its proximity to substance abuse. Drawing from human experience and comprehensive research, the work examines how alcoholism both fuels and undermines the creative process, contextualizing these themes within the isolating and demanding life of a road comedian.
Set in the early 1990s, Road Work follows Jonny Masters, a struggling comic navigating the unforgiving circuits of the American Midwest. Through Jonny’s journey, the novel delves into the symbiotic yet destructive relationship between alcohol and artistic ambition. It highlights the physical and psychological toll of the addiction-recovery cycle, especially within professions where vulnerability and self-expression are currency. By portraying the daily grind of comedy—from unglamorous travel to the pressures of performing for often hostile audiences—the narrative offers a raw, unvarnished look at the tenuous balance between professional success and personal well-being. The novel captures Jonny’s internal struggles while maintaining a broader, nuanced perspective on addiction’s cultural and artistic implications. Informed by a rich tradition of literary and real-world narratives, the work seeks to contextualize the role of addiction in the lives of artists and present a compelling inquiry into the myths surrounding addiction as a creative catalyst and the romanticized archetype of the troubled genius. As such, this thesis seeks to illuminate the complexities of sobriety, artistic reinvention, and the human condition within the dynamic and often unforgiving world of standup comedy
