Guide to Using Onionskin Analysis Code (U)
Abstract
This document is a guide to using Rcode written for the purpose of analyzing onionskin experiments. We expect the user to be very familiar with statistical methods and the R programming language. For more details about onionskin experiments and the statistical methods mentioned in this document see Storlie, Fugate, et al. (2013). Engineers at LANL experiment with detonators and high explosives to assess performance. The experimental unit, called an onionskin, is a hemisphere consisting of a detonator and a booster pellet surrounded by explosive material. When the detonator explodes, a streak camera mounted above the pole of the hemisphere records when the shock wave arrives at the surface. The output from the camera is a twodimensional image that is transformed into a curve that shows the arrival time as a function of polar angle. The statistical challenge is to characterize a baseline population of arrival time curves and to compare the baseline curves to curves from a new, socalled, test series. The hope is that the new test series of curves is statistically similar to the baseline population.

The HEFF Code combines a simple boundaryelement method of stress analysis with the closed form solutions for constant or exponentially decaying heat sources in an infinite elastic body to obtain an approximate method for analysis of underground excavations in a rock mass with heat generation. This manual describes the theoretical basis for the code, the code structure, model preparation, and step taken to assure that the code correctly performs its intended functions. The material contained within the report addresses the Software Quality Assurance Requirements for the Yucca Mountain Site Characterization Project. 13 refs., 26 figs., 14 tabs.

CADISE [Crosssection Analysis with Data Interpolation on a Standard Energy grid]: A crossSection Analysis Code for the IBM PC/AT; Users` guide
CADISE (Crosssection Analysis with Data Interpolation on a Standard Energy grid) is a computer program for the IBM PC/AT. It permits the compilation and preparation of calculated nuclear crosssection excitation functions for energygroup averaging and for further use in other codes that perform activation calculations for radiochemical device diagnostics. CADISE enables the user to graphically display the calculated crosssections as a function of incident energy, to modify and manipulate these excitation functions where necessary, and then, by means of analytical fitting and interpolating, to construct an output file with a finer energy grid suitable for group averaging. 5 refs. 
FRAC (failure rate analysis code): a computer program for analysis of variance of failure rates. An application user's guide
Probabilistic risk assessments (PRAs) require estimates of the failure rates of various components whose failure modes appear in the event and fault trees used to quantify accident sequences. Several reliability data bases have been designed for use in providing the necessary reliability data to be used in constructing these estimates. In the nuclear industry, the Nuclear Plant Reliability Data System (NPRDS) and the InPlant Reliability Data System (IRPDS), among others, were designed for this purpose. An important characteristic of such data bases is the selection and identification of numerous factors used to classify each component that is reported and themore » 
Guide to Using the WIND Toolkit Validation Code
In response to the U.S. Department of Energy's goal of using 20% wind energy by 2030, the Wind Integration National Dataset (WIND) Toolkit was created to provide information on wind speed, wind direction, temperature, surface air pressure, and air density on more than 126,000 locations across the United States from 2007 to 2013. The numerical weather prediction model output, gridded at 2km and at a 5minute resolution, was further converted to detail the wind power production time series of existing and potential wind facility sites. For users of the dataset it is important that the information presented in the WINDmore » 
Revised simplex code for LP problems using orthogonal decomposition: a user's guide. [LPMG, LPMGB, and LPQT, in FORTRAN]
The mathematical and algorithmic details that are necessary for reliable, generalpurpose linear programming software are documented. FORTRAN subprograms LPMGB( ) and LPMG( ) are described. These subprograms accept a linear minimization problem subject to linear equality constraints with lower and upper bounds on selected variables. The subprogram LPMGB( ) performs preliminary transformations on the given problem. These include the elimination of free variables and normalization of the bounds to be just nonnegativity and upper bounds on selected variables. There remains a core linear programming problem that is solved with subprogram LPMG( ). Further topics discussed in this report are scaling,more »
