Author(s)
Salifou Sidi Malick, Matthew Molek, Katherine C. Morris
This document describes the Constraint Generator. The Constraint Generator is a tool developed at NIST to automate the generation of schematron scripts for an advance validation of XML documents. The tool allows the user to open an XSD schema, view a tree

MTCONNECT-BASED KAIZEN FOR MACHINE TOOL PROCESSES

August 18, 2010
Author(s)
Byeong Eon Lee, John L. Michaloski, Frederick M. Proctor, Sid Venkatesh, Nils Bengtsson
Kaizen is a part of Lean Manufacturing that focuses on the concept of continuous improvement to reduce waste. For implementing Kaizen on the factory floor, comprehensive and efficient tools for data acquisition, process measurement and analysis are

Metadata for Long Term Preservation of Product Data

August 2, 2010
Author(s)
Joshua Lubell
Product data can usefully be defined as structured information about objects which are produced by industrial and business processes. In terms of information types, data formats, usage, and lifespan, product data is both complex and diverse, encompassing

Ontological Product Modeling for Collaborative Design

July 22, 2010
Author(s)
Conrad E. Bock, XuanFang Zha, Hyo-won Suh, Jae H. Lee
This paper shows how to combine ontological and model-based techniques in languages that facilitate collaborative design exploration. The proposed approach uses ontology to capture alternative designs and incremental refinements that meet requirements and

The 2009 RoboCup Competitions took place in Graz Austria in July of 2009. The Virtual Robot Rescue Competition included 11 competitors from 10 different countries. The main objective of this competition is to utilize teams of robots to perform an urban

A RESTful Web Service for Virtual Supply Chain Time Management

March 25, 2010
Author(s)
Guillaume Radde
A common issue when building distributed simulations is the issue of time management. Each discrete event simulation has its own notion of time, and a mechanism needs to be set up to allow each simulation to run at the same pace. Different architectures
