Influence Metrics for Value and Utility Functions

Imbro, Dennis R.; Pless, Daniel

Methods are proposed to measure the sensitivity of utility or value function to the variations of attribute values for Multi-Criteria Decision Analyses that are based on functions that cannot be expressed as a weighted sum of the attribute values. These measures, called factor Influence Metrics, can be used to examine the characteristics of the option scoring algorithm and help verify the algorithm is consistent with decision makers value structure and processes.

HEDP Workshop Summary: High-Intensity Laser Plasma (HILP) group

Geissel, Matthias; Geddes, Cameron; Willingale, Louise; Winjum, Benjamin

Advances in HEDP research and limitations in currently established theories and models challenge us to better understand how high-intensity (>1014 W/cm2) laser light couples to plasmas. Considering both energy transfer processes and the resulting particle-beam and radiation generation, we find one overarching question: How do we understand, predict, and control laser-plasma interactions and laser-driven particle beams?

Well Casing Baseline Analysis for the Bayou Choctaw Strategic Petroleum Reserve Site

Moriarty, Dylan M.

This report analyzes data from multi-arm caliper (MAC) surveys taken at the Bayou Choctaw Strategic Petroleum Reserve site to determine baseline statistics for the original innermost cemented casing or the subsequent installed liner. Along with analyzing the internal diameters from the MAC surveys, this analysis looks to approximate casing weight, an important metric for determining the strength of well sections. Casing weight is calculated for each section, survey, and well. Results from the analysis show most wells reflect the dimensions in the original as-built drawings. There are, however, several exceptions. Some well sections have calculated wall thicknesses outside API tolerance. In addition, some well section depths differ from the as-built drawings. All results are discussed on a well-by-well basis. Where applicable, information from this report should be used to update as-built drawings and aid in creating more accurate well models for future studies.

Paraniso 1.0: 3-D Full Waveform Seismic Simulation in General Anisotropic Media

Preston, Leiph

Many geologic materials and minerals are seismically anisotropic, with the most general anisotropic material having up to 21 independent elastic coefficients. This report outlines the development of a 3-D, generally anisotropic, linear elastic full waveform finite-difference solver. First, a mathematical description of the solution equations will be described. The finite-difference implementation of these equations will then be shown. Finally, a comparison of results from this new solver to other solutions will be provided as verification that the new algorithm can accurately replicate these solutions.

ParelastiFWI 1.0 User Guide

Preston, Leiph

ParelastiFWl is a python-based frontend to the seismic full waveform inversion process using Sandia Geophysics Department's 3-D isotropic elastic full waveform simulation code, Parelasti. The arguments one provides to ParelastiFWl guide the full waveform inversion process, including resolution of the inversion grid and basic regularization. This report outlines the user flags and ParelastiFWI usage to control the full waveform inversion procedure.

Site Environmental Report for 2018 Sandia National Laboratories, California

Jadhav, Pradnya A.

Sandia National Laboratories, California (SNL/CA) is a Department of Energy (DOE) facility. The management and operations of the facility are under a contract with the DOE's National Nuclear Security Administration (NNSA). On May 1, 2017, the name of the management and operating contractor changed from Sandia Corporation to National Technology & Engineering Solutions of Sandia, LLC (NTESS). The DOE, NNSA, Sandia Field Office administers the contract and oversees contractor operations at the site. DOE and its management and operating contractor for Sandia are committed to safeguarding environmental protection, compliance, and sustainability and to ensuring the validity and accuracy of the monitoring data presented in this Annual Site Environmental Report. This Site Environmental Report for 2018 was prepared in accordance with DOE Order 231.1 B, Environment, Safety and Health Reporting (DOE 2012). The report provides a summary of environmental monitoring information and compliance activities that occurred at SNL/CA during calendar year 2018, unless noted otherwise. General site and environmental program information is also included.
