Towards an Approach for Knowledge-Based Road Detection

June 26, 2006
Author(s)
Mike Foedisch, Craig I. Schlenoff, Michael O. Shneier
Our previous work on road detection suggests the usage of prior knowledge in order to improve performance. In this paper we will explain our motivation for a novel approach, define requirements and point out issues, particularly concerning the

Trajectory Generation for an On-Road Autonomous Vehicle

June 26, 2006
Author(s)
John A. Horst, Anthony J. Barbera
We describe an algorithm that generates a smooth trajectory (position, velocity, and acceleration) for a non-holonomic vehicle autonomously navigating within the constraints of lanes in a road. The technique models both vehicle paths and lane segments as

Using 4D/RCS to Address AI Knowledge Integration

June 26, 2006
Author(s)
Craig I. Schlenoff, James S. Albus, Elena R. Messina, Tony Barbera, Rajmohan (. Madhavan, Stephen B. Balakirsky
In this paper, we show how 4D/RCS incorporates and integrates multiple types of disparate knowledge representation techniques into a common, unifying architecture. 4D/RCS is based on the supposition that different knowledge representation techniques offer

Validating Portability of Step-NC Tool Center Programming

June 26, 2006
Author(s)
Sid Venkatesh, David Odendahl, Xun W. Xu, John L. Michaloski, Frederick M. Proctor, Thomas Kramer
A joint effort between Boeing and the National Institute of Standards and Technology (NIST) was undertaken for validating and evaluating STEP AP238 (STEP-NC) Conformance Class 1 (CC1) for 5-axis machining. STEP-NC is a new manufacturing standard to support

Entity Knowledge Model Supporting Intelligent Systems

June 20, 2006
Author(s)
Hui-Min Huang, James S. Albus, Elena R. Messina, Harry A. Scott, Maris Juberts
Intelligent systems operate in uncertain and complex environments. In order to achieve their goals, these systems require rich and updated knowledge about the environment and about their own capabilities to enable proper decision making processes. A

A Web Service-Based Reconfigurable Testbed for Business-to-Business (B2B) Integration

June 1, 2006
Author(s)
B Jeong, Jungyub Woo, Hyunbo Cho, Boonserm Kulvatunyou, James Lee
Several types of standards and corresponding software solutions have been created to enable business-to-business (B2B) integration. Testing for conformance and interoperability among these solutions are inter-dependent. This signifies the needs to make

Implementing XML Schema Naming and Design Rules

June 1, 2006
Author(s)
Joshua Lubell, Boonserm Kulvatunyou, Katherine C. Morris, Betty Harvey
We are building a methodology and tool kit for encoding XML schema Naming and Design Rules (NDRs) in a computer-interpretable fashion, enabling automated rule enforcement and improving schema quality. Through our experience implementing rules from various

Dynamic Simulation and Modeling of a Road Vehicle

February 2, 2006
Author(s)
Tsung-Ming Tsai
Automated driving of road vehicles needs to use a simulation environment to develop control programs. A vehicle dynamic simulation program was implemented into a computer system. It contains a vehicle dynamic model that models all essential parts of a

Overview of the First Advanced Technology Evaluations for ASSIST

January 31, 2006
Author(s)
Craig I. Schlenoff, Brian A. Weiss, Michelle P. Steves, Ann M. Virts, Michael O. Shneier, Michael Linegang
ASSIST (Advanced Soldier Sensor Information Systems Technology) is a DARPA-funded effort whose goal is to exploit soldier-worn sensors to augment the soldier s recall and reporting capability to enhance situation understanding. ASSIST is separated into two

USARSim: Providing a Framework for Multi-Robot Performance Evaluation

January 31, 2006
Author(s)
Stephen B. Balakirsky, Christopher J. Scrapper Jr, Stefano Carpin, M L. Lewis
Research efforts in urban search and rescue robotics have grown substantially in recent years. Two important robotic competitions (a robot physical league and a high-level infrastructure simulation league) were established in 2001 under the RoboCup

Recommended Objective Test Procedures for Road Departure Crash Warning Systems

January 6, 2006
Author(s)
Sandor S. Szabo, Richard J. Norcross
Under the auspices of the Department of Transportation Intelligent Vehicle Initiative, the National Highway Traffic and Safety Administration (NHTSA) is evaluating the safety benefits of Road Departure Crash Warning Systems (RDCWS). These systems warn

Temporal Range Registration for Unmanned Ground and Aerial Vehicles

November 30, 2005
Author(s)
Rajmohan (. Madhavan, Tsai H. Hong, Elena R. Messina
An iterative temporal registration algorithm is presented in this article for registering 8 3D range images obtained from unmanned ground and aerial vehicles traversing unstructured 9 environments. We are primarily motivated by the development of 3D

Design and Modeling of Thermally Actuated MEMS Nanopositioners

November 11, 2005
Author(s)
Sebastien Bergna, Jason J. Gorman, Nicholas G. Dagalakis
Several micro-scale nanopositioning mechanisms, or MEMS nanopositioners, have been developed for application in nanotechnology and optical sensors. In this paper, the design and modeling of these devices is presented along with initial experimental results

Knowledge Representation and Decision Making for Mobile Robots

July 13, 2005
Author(s)
Elena R. Messina, Stephen B. Balakirsky
Knowledge is central to a mobile robot's ability to carry out its missions and adapt to changes in the environment it is traversing. The knowledge subsystem must support acquisition of information from external sources, maintain prior knowledge, infer new

SysML and UML 2 Support for Activity Modeling

June 1, 2005
Author(s)
Conrad E. Bock
This article describes activity modeling as specified by the Systems Modeling Language (SysML) and the finalization of the Unified Modeling Language version 2 (UML 2). It reviews and updates an earlier proposed alignment between Enhanced Functional Flow

HiCASS Target Tracking Sensor Study

May 20, 2005
