Heretofore, such modeling has been accomplished by means of unique software for each application. In contrast,...

U-HUNTER (also called “UXOHUNTER”) is a computer program that affords knowledge-based real-time sensor- fusion and display capabilities for detecting buried objects and materials of interest. U-HUNTER is intended especially for inferring the presence of buried unexploded ordnance and...

A report presents a study of the complexity of an algorithm that performs model-based diagnosis of a complex hardware system. [In model-based diagnosis, an algorithm detects logical inconsistencies between observational data and a description (mathematical model) of the system.] In the study, the problem of...

The NASGRO 3.0 computer program is an advanced version of a program used by NASA and the European Space Agency for fracture-control analysis of space-system structures and other hardware. The prior version, NASA/FLAGRO 2.0, was described in “Updated Fatigue-Crack-Growth and...

SEQ_GEN is a component of the Sequence Subsystem computer program, which assists in generating a sequence of commands to be executed by a control computer aboard a spacecraft to perform scientific observations and supporting engineering actions in response to requests by numerous users. SEQ_GEN assists a...

Closed Loop Accounting Management System (CLAMS) is a computer program for Web-based distribution and tracking of memoranda within an organization. An item for distribution is entered by a user who has administrative access. The item is assigned to affected users, to whom e-mail messages are...

A C-language computer program implemented as firmware controls the operations of a microprocessor on a 3-by- 1-inch (approximately 76-by-25-mm) motion-control circuit board denoted a widget board. The firmware implements a serial communication interface according to the inter integrated circuit bus...

The EMNet computer program has been developed to overcome the difficulties and reduce the errors that, heretofore, have been encountered in transferring data from computer-aided design (CAD) systems to computer numerically controlled (CNC) machines. EMNet could improve operations in almost...

A computer program implements several aspects of the International Temperature Scale of 1990 (ITS90).

The Gyroscope Automated Testbed (GAT) is a fully automated inertial device characterization testbed. Rotational response parameterization and shortterm noise stability analysis are the fundamental principles behind the system. Complete response characterization, bias stability, sensitivity, and range are supported along...

JIFI (Jet Propulsion Laboratory's Implementation of a Fault Injector) is a computer program for studying the ability of a computer to tolerate, detect, and/or recover from faults (that is, bit errors). JIFI affords the capability to inject faults into user-specified central- processing-unit (CPU)...

A software library and set of programs largely automate the geometric calibration of video cameras. Developed especially for robotic vision systems, this software generates the information needed to determine the three-dimensional (3D) positions of objects that appear in two- dimensional (2D)...

KPP is a computer program that serves as a preprocessor for VHDL code. [“VHDL” signifies VHSIC Hardware Description Language, which is a language used by the United States Department of Defense for describing, designing, and simulating very-high-speed integrated circuits (VHSICs).] KPP is based on, and similar...

A computer program assists engineers in analyzing data on the performances of actuators of fuel and oxidizer valves in the main engines of the space shuttle.
