A Confidence Limit Computer (open access)

A Confidence Limit Computer

Introduction: Confidence limits as a mathematical tool are applicable to many development engineering and production engineering situations. In order to make confidence limits readily available to engineers, a computer was designed which will approximate certain confidence limits.

Curves for Estimating Low Blast Over-Pressure (open access)

Curves for Estimating Low Blast Over-Pressure

A plot of overpressure versus distance is presented for the fractional psi pressure level. The plot provides a rapid and simple means of estimating the permissible yield at any distance from settled areas.

An Approximate Solution for the Vaporization of Liquid Droplets Formed During Re-Entry Ablation (open access)

An Approximate Solution for the Vaporization of Liquid Droplets Formed During Re-Entry Ablation

Introduction: The purpose of this report is to describe a mathematical model which will help solve the ultimate-particle-size problem by estimating the evaporative mass losses during that portion of re-entry when the fuel is in liquid form.

Power Cable Carrier Control (PC3) System (open access)

Power Cable Carrier Control (PC3) System

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.

Basic Data Report for Drilling and Hydrologic Testing of Drillhole DOE-2 at the Waste Isolation Pilot Plant (WIPP) Site (open access)

Basic Data Report for Drilling and Hydrologic Testing of Drillhole DOE-2 at the Waste Isolation Pilot Plant (WIPP) Site

From abstract: Drillhole DOE-2 was drilled to investigate a structural depression marked by the downward displacement of stratigraphic markers in the Salado Formation ~ 2 mi north of the center of the WIPP site. This depression was named informally after the shallow borehole FC-92 in which the structure was described. The presence of the depression was confirmed by drilling.

High Explosive Crater Studies: Tuff (open access)

High Explosive Crater Studies: Tuff

Abstract: "Spherical charges of TNT, each weighing 256 pounds, were exploded at various depths in tuff to determine apparent crater dimensions in a soft rock. No craters were obtained for depths of burst equal to or greater than 13.3 feet. It was deduced that rock fragments were sufficiently large that charges of greater magnitude should be employed for crater experiments intended as models of nuclear explosions."
