A sendmail. cf scheme for a large network

Description: Like most large networked sites our users depend heavily on the electronic mail system for both internal and off-site communications. Unfortunately the sendmail.cf file, which is used to control the behavior of the sendmail program, is somewhat cryptic and difficult to decipher for the neophyte. So, on one hand you have a highly visible, frequently used utility, and on the other hand a not-so-easily acquired system administration forte. Here is the sendmail topology of our site, what premises w… more

Instrumentation of dynamic gas pulse loading system

Description: The overall goal of this work is to further develop and field test a system of stimulating oil and gas wells, which increases the effective radius of the well bore so that more oil can flow into it, by recording pressure during the gas generation phase in real time so that fractures can be induced more predictably in the producing formation. Task 1: Complete the laboratory studies currently underway with the prototype model of the instrumentation currently being studied. Task 2: Perform field t… more

MACRO1: a code to test a methodology for analyzing nuclear-waste management systems

Description: The code is primarily a manager of probabilistic data and deterministic mathematical models. The user determines the desired aggregation of the available models into a composite model of a physical system. MACRO1 then propagates the finite probability distributions of the inputs to the model to finite probability distributions over the outputs. MACRO1 has been applied to a sample analysis of a nuclear-waste repository, and its results compared satisfactorily with previously obtained Monte Carlo… more

Plasma confinement calculations for TIBER-II: Final report

Description: This paper compares the empirically based TIBER II design parameters against the reactor parameters of a tokamak based on a theoretical model of heat transport. The motivation behind this project is the following. The present TIBER-II design is based on an empirical scaling of confinement time tau/sub E/ known as Kaye-Goldston scaling. This empirical scaling is based on data from tokamak plasmas whose temperatures did not exceed a few keV, while the TIBER-II requires electron temperatures of 25… more

PHIGS PLUS for scientific graphics

Description: This paper gives a brief overview of the use of computer graphics standards in the scientific community. It particularly details how how PHIGS PLUS meets the needs of users at the Lawrence Livermore National Laboratory. Although standards for computer graphics have improved substantially over the past decade, their acceptance in the scientific community has been slow. As the use and diversity of computers has increased, the scientific graphics libraries have not been able to keep pace with the … more

GRAY: a program to calculate gray-body radiation heat-transfer view factors from black-body view factors

Description: Program GRAY is written to perform the matrix manipulations necessary to convert black-body radiation heat-transfer view factors to gray-body view factors as required by thermal analyzer codes. The black-body view factors contain only geometric relationships. Program GRAY allows the effects of multiple gray-body reflections to be included. The resulting effective gray-body factors can then be used with the corresponding fourth-power temperature differences to obtain the net radiative heat flux.… more

Energy deposition by high energy protons: comparison of theory and experiment. [HETC computer code]

Description: The ability of the HETC computer code to calculate energy deposited by proton beams of 0.8 to 28.5 GeV in composite targets was evaluated by comparing calculated results with experimental data. The experimental assembly consisted of /sup 238/U shower plates separated by an air gap from a CH/sub 2///sup 238/U detector plate. For protons in the range 0.8 to 5 GeV, HETC data on energy deposited can be considered accurate to a few tens of percent or better for the shower-plate part of the assembly … more

Fluorescent scattering by molecules embedded in small particles. Progress report, May 1, 1977--October 31, 1978. [Summaries of research activities at Clarkson College of Technology]

Description: A model for the fluorescence and Raman scattering by molecules that comprise or are embedded in small particles was developed and numerical calculations performed. The emphasis during this first year of the contract was on writing and testing the computer programs necessary for numerical calculations and on demonstrating the extent of the potential effects that the geometrical and optical properties of the particle would have on the Raman and fluorescent emissions. For the purpose of demonstrat… more

Geothermal reservoir engineering computer code comparison and validation using the GEONZ simulator program

Description: It was originally proposed to use the GEOTHERM geothermal simulator program to prepare solutions to the first five of the six Department of Energy computer code comparison sets. Valid solutions were anticipated in all of the five problems attempted, but it was expected that problems 3 and 4 might present some difficulties. A more recent version of the program, called GEONZ became available and was used successfully on problems 3 and 4. The new program, GEONZ, had additional capabilities that en… more

Nonlinear hydrodynamics. Lecture 9

Description: A very sophisticated method for calculating the stability and pulsations of stars which make contact with actual observations of the stellar behavior, hydrodynamic calculations are very simple in principle. Conservation of mass can be accounted for by having mass shells that are fixed with their mass for all time. Motions of these shells can be calculated by taking the difference between the external force of gravity and that from the local pressure gradient. The conservation of energy can be c… more

ADVANCED MIXING MODELS

Description: The process of recovering and processing High Level Waste (HLW) the waste in storage tanks at the Savannah River Site (SRS) typically requires mixing the contents of the tank with one to four mixers (pumps) located within the tank. The typical criteria to establish a mixed condition in a tank are based on the number of pumps in operation and the time duration of operation. To ensure that a mixed condition is achieved, operating times are typically set conservatively long. This approach results … more

PRETART/TARTV user's manual. [Preprocessors for checking geometry before TARTNP runs]

Description: PRETART and TARTV are preprocessors for input decks for TARTNP, a coupled neutron--photon Monte Carlo transport code. They accept the normal TARTNP input decks. The purpose of these routines is to aid users in checking their geometry before making a TARTNP run. PRETART finds the volume of each zone, or of any selected subset of zones. When the volumes of all zones are found, the user may select a percentage of random checking for gaps or overlaps between the zones. If gaps or overlaps are found… more

Higher Order Modes HOM___s in Coupled Cavities of the Flash Module ACC39

Description: We analyse the higher order modes (HOM's) in the 3.9GHz bunch shaping cavities installed in the FLASH facility at DESY. A suite of finite element computer codes (including HFSS and ACE3P) and globalised scattering matrix calculations (GSM) are used to investigate the modes in these cavities. This study is primarily focused on the dipole component of the multiband expansion of the wakefield, with the emphasis being on the development of a HOM-based BPM system for ACC39. Coupled inter-cavity mode… more

Description: The ATD code is a multi-purpose code which reduces data files produced by a digitizer. It contains all of the features for the basic unpacking, scaling, and plotting of digitized data files. More advanced capabilities are also available. Digital filtering, spectral analysis, and statistical analysis, among others, allow the engineer the capability to analyze and display time history data. In contrast to codes such as DYMEC, the data files are typically of high frequency and short duration, repr… more

Generalized pattern search algorithms with adaptive precision function evaluations

Description: In the literature on generalized pattern search algorithms, convergence to a stationary point of a once continuously differentiable cost function is established under the assumption that the cost function can be evaluated exactly. However, there is a large class of engineering problems where the numerical evaluation of the cost function involves the solution of systems of differential algebraic equations. Since the termination criteria of the numerical solvers often depend on the design paramet… more
