From summary: This report concerns the theoretical evaluation and experimental development of special thermocouples capable of being accurately located at or near the surface of metal structures to permit measurement of temperature distribution through the strictures.

A control system has been developed that uses a carrier signal imposed on an existing ac power circuit to transmit commands. This system was specifically developed to control an entire solar collector field by sending sun-tracking information to the trough collectors or by commanding them to assume safe positions (STOW) if out-of-limit conditions were encountered. Objectives were to develop a control system that operates reliably and has enough functions to control an entire collector field, yet do it at less cost than for conventional approaches. Development, design, operating characteristics, and field testing and results of the new system, the Power Cable Carrier Control (PC³) System are described.

From summary: The purpose of this analysis is to provide photovoltaic (P/V) system design and field engineers with an understanding of the primary factors which can cause individual P/V cells in a module or an array to be forced into reverse bias and eventual failure and to provide guidelines for the adequate protection of the cells.

Abstract: Force, moment, and center of pressure information are presented for four models of the Hi-Lo configuration.

Abstract: This report describes the computer simulation code SOLSTOR. The code simulates energy systems in which electricity is generated by either a photovoltaic (PV) system or a wind turbine generator (WTG). Storage may or may not be present. Backup electricity, if needed, is provided either from a utility grid or from a fuel-burning generator. SOLSTOR minimizes the life cycle cost of providing energy by choosing the optimal solar or wind system component sizes. Rates for electricity purchased from the grid can include time-of-day (TOD) energy charges as well as time-of-day peak demand changes. Sell-back to the grid of excess collected energy is also considered.

From summary: The purpose of the study is to develop information that will contribute to the definition of the potential role of photovoltaics in meeting future energy demands in agriculture.

From introduction: The objectives of the technical effort are to identify and characterize agricultural energy demands that can effectively use P/V power systems and to determine performance and cost-estimates for the designs.

Forward: The Final Report summarizes the findings and project work in conjunction with the "Photovoltaic" Applications Definition and Photovoltaic System Definition Study in the Agricultural Sector" under Contract Number 07-6951.

A digital comparator has been designed to flag data which goes above a maximum limit or below a minimum limit.

The primary purpose of this study was to find a method for establishing component reliability requirements from system reliability specifications, because component reliability requirements are presently arbitrarily and vaguely defined.

Abstract: Presented here are working graphs of pressure, density, velocity, and temperature from the Los Alamos Scientific Laboratory calculations (IBM Problem M) of a spherically symmetric explosion in a homogeneous atmosphere.

Abstract: This report presents a simple, quantitative analytical method for determining the percent of a particular group or structure within a urethane compound by means of the infrared spectrophotometer.

Introduction: Neutron measurements were made in the pulsed reactor building and on the safety screen of the pulsed reactor in order to determine the neutron yield of the reactor as a function of (1) distance from the reactor centerline, (2) direction in the reactor building, and (3) position on the reactor safety screen.

Abstract: "This report presents the characteristics incorporated in the design of a ballistic rocket system that is capable of carrying recoverable payloads varying in weight from 75 to 200 pounds to altitudes of 600,000 to 1,000,000 feet (msl)."

Abstract: "Weights of linear high-explosive charges fired on the Yucca Lake playa of the Nevada Test Site varied from 0.23 to 42.7 pounds per foot. Crater and ditch dimensions and volumes resulting from these shots, fired during the fall of 1959 and spring of 1960, are presented here as a function of charge burst depths. Scaling relationships determined are as expected; i.e., square-root scaling of linear-charge weight per foot for ditch width and depth and a direct linear-charge weight relationship to ditch volume are obtained. Permanent ground surface displacement varies as the -3.22 power of the scaled distance from the charge. Detonation effects, charge shape effects, ditch erosion, and ditch cross sections are discussed. The appendixes present Toboggan data, results of soil investigation, and mathematical treatment given the data."

"Eight high-explosive charges weighing 8 to 1000 pounds were detonated in playa. Each event included 24 to 40 locations of tracer material in the expected crater region. The objective was to obtain data relating the origin of crater ejecta to its depositional location. Resulting data are presented for craters, ejecta areal densities, crater and ejecta mass quantities, tracer dispersion, and an empirical prediction model."

Foreword: The purpose of the present work was to collect and tabulate data on fused salt mixtures.

Abstract: "An exploding copper wire, one millimeter in diameter, 30 centimeters long, has been developed as a fuse component for a Los Alamos capacitor energy source to be employed in controlled thermonuclear research studies. The fuse allows the passage of the high normal duty "action" (13,700 ampere-coulombs per capacitor) at a 20-second repetition rate. However, it interrupts the circuit to a shorted capacitor in 12 microseconds, thereby protecting the faulted capacitor from explosive energy consumption. The initial phase of the development included observations of various metals (copper, silver, iron, and nickel) as well as various configurations (straight wires, helixes, foils, and tubes). Direct scaling of previous small exploding wire studies at Sandia Corporation was demonstrated with scaling factors up to 700,000."
