Test Sequence Generation for Integration Testing of Component Software

November 22, 2007
Author(s)
Leonard J. Gallagher, Jeff Offutt
Ensuring high object interoperability is a goal of integration testing for object-oriented software. When messages are sent, receiving objects should respond as intended. Ensuring this is especially difficult when software uses components that are

Metrics for Evaluating Human-Information Interaction Systems

July 24, 2006
Author(s)
Jean C. Scholtz
Society today has a wealth of information available due to information technology. The challenge facing researchers working in information access is how to help users easily locate the information needed. Evaluation methodologies and metrics are important

Representation of Heterogeneous Material Properties in the Core Product Model

June 1, 2006
Author(s)
Arpan Biswas, Steven J. Fenves, V Shapiro, Ram D. Sriram
The Core Product Model (CPM) was developed at NIST as a high level abstraction for representing product related information, to support data exchange, in a distributive and a collaborative environment. In this paper, we extend the CPM to components with

AutoBid: System for Police Patrol Selection.

November 1, 2001
Author(s)
S F. Weber, Amy S. Rushing
AutoBid is designed to help police fleet administrators select the patrol vehicle that is best suited to the needs of their department. The system is based on vehicle performance test data for police patrol package models published annually by the Michigan

BLCC 5.0-01.

April 1, 2001
Author(s)
S Fuller, A S. Boyles
The BLCC5 Building Life-Cycle Cost Program provides economic analysis of projects for which both initial capital costs and future operational costs need to be considered. The program is useful for evaluating the long-term costs and savings of energy and

Countermeasures for Mobile Agent Security

November 1, 2000
Author(s)
Wayne Jansen
Security is an important issue for the widespread deployment of applications based on agent technology. It is generally agreed that without the proper countermeasures in place, use of agent-based applications will be severely impeded. However, not all

LINDENS: A program for lineament length and density analysis

November 1, 2000
Author(s)
Antonio M. Casas, Angel Cortes, Adolfo Maestro, M. Asuncion Soriano, Andres Riaguas, Javier Bernal
Analysis of lineaments from satellite images normally includes the determination of their orientation and density. The spatial variation in the orientation and/or number of lineaments must be obtained by means of a network of cells, the lineaments included

Green's Function for Steady-State Heat Conduction in a Bimaterial Composite Solid

June 1, 2000
Author(s)
J R. Berger, J L. Skilowitz, Vinod K. Tewary
The derivation of a Green's function for steady-state heat conduction in anisotropic bimaterials is presented. The Green's function is obtained through a Fourier representation to obtain both free-space, singular parts and region-dependent, regular parts

Dynamic Equations for a Two-Link Flexible Robot Arm

December 30, 1988
Author(s)
Jonathan W. Lee, B Wang
The dynamic equations for a two-link flexible robot arm have been derived rigorously. The arm is moving in the vertical plane. The payload is simulated by attaching additional masses to the arm at any specific locations. Although the governing equations of

Calibration of a Camera and Light Source by Fitting to a Physical Model

December 31, 1986
Author(s)
P Mansbach
This paper describes the calibration of a camera-and-plane-of-light ranging system. Equations are derived which relate the image coordinates in the camera to the external coordinate system. These equations contain coefficients which are functions of the

Model-Based Strategies for High-Level Robot Vision

July 31, 1986
Author(s)
Michael O. Shneier, Ronald Lumia, Ernest Kent
The higher levels of a sensory system for a robot manipulator are described. The sensory system constructs and maintains a representation of the world in a form suitable for fast responses to questions posed by other robot subsystems. This is achieved by

Simulation of the Hydration Kinetics and Elastic Moduli of Cement Mortars by Microstructural Modeling

September 15, 2014
Author(s)
Luca Valentini, Matteo Parisatto, Vincenzo Russo, Giorgio Ferrari, Jeffrey W. Bullard, Ross J. Angel, Maria C. Dalconi, Gilberto Artioli
The ability of the VCCTL microstructural model to predict the hydration kinetics and elastic moduli of cement materials was tested by coupling a series of computer simulations and laboratory experiments, using different cements. The novel aspects of this
