2.5 D Cavity Balancing
(2002-01)Cavity balancing is the process of altering the flow front within a cavity through thickness and design changes such that the desired fill pattern is achieved. The 2 dimensional (2D) cavity-balancing algorithm, developed ... -
Accuracy Analysis and Improvement for Direct Laser Sintering
(2004-01)The accuracy issue of a rapid prototyping-direct laser sintering system is studied in this paper. The sources of errors are analyzed for their contribution to the final accuracy of built parts. The error sources are related ... -
An Analytical Solution on Convective and Diffusive Transport of Analyte in Laminar Flow of Microfluidic Slit
(2004-01)Microfluidic devices could find applications in many areas, such as BioMEMs, miniature fuel cells and microfluidic cooling of electronic circuitry. One of the important considerations of microfluidic device in analytical ... -
An Application of Augmented Reality (AR) in the Teaching of an Arc Welding Robot
(2005-01)Augmented Reality (AR) is an emerging technology that utilizes computer vision methods to overlay virtual objects onto the real world scene so as to make them appear to co-exist with the real objects. Its main objective ... -
Application of Stereo Imaging to Atomic Force Microscopy
(2002-01)Metrological data from sample surfaces can be obtained by using a variety of profilometry methods. Atomic Force Microscopy (AFM), which relies on contact inter-atomic forces to extract topographical images of a sample, ... -
Assembly Design and Evaluation in an Augmented Reality Environment
(2005-01)The technologies and methodologies of assembly design and evaluation in the early design stage are highly significant to product development. This paper looks at a promising technology to mix real components (e.g. physical ... -
Assembly Guidance in Augmented Reality Environments Using a Virtual Interactive Tool
(2005-01)The application of augmented reality (AR) technology for assembly guidance is a novel approach in the traditional manufacturing domain. In this paper, we propose an AR approach for assembly guidance using a virtual interactive ... -
Atomic Force Microscope: Modeling, Simulations, and Experiments
(2002-01)The quality of atomic force microscope (AFM) data strongly depends on scan and controller parameters. Data artifacts can result from poor dynamic response of the instrument. In order to achieve reliable data, dynamic ... -
A Base Stock Inventory Model for a Remanufacturable Product
(2003-01)We report on an industrial project in which we developed an inventory model to provide decision support for the design and deployment of the field service support system for a remanufacturable product. The product was a ... -
The Benefits of Re-Evaluating Real-Time Fulfillment Decisions
(2005-01)At the time of a customer order, the e-tailer assigns the order to one or more of its order fulfillment centers, and/or to drop shippers, so as to minimize procurement and transportation costs, based on the available current ... -
Building a Document Corpus for Manufacturing Knowledge Retrieval
(2004-01)When faced with challenging technical problems, R&D personnel would often turn to technical papers to seek inspiration for a solution. The building of a corpus of such papers and the easy retrieval of relevant papers by ... -
Characterization and Modeling of Chemical-Mechanical Polishing for Polysilicon Microstructures
(2004-01)Long the dominant method of wafer planarization in the integrated circuit (IC) industry, chemical-mechanical polishing is starting to play an important role in microelectromechnical systems (MEMS). We present an experiment ... -
Characterization of Diamond-Like Film after Focused Ion Beam Processing
(2003-01)Optical properties (transmission and refractive index) and chemical structure (XPS) of diamond-like coating (DLC) film before and after focused ion beam milling (FIBM) process, were investigated in this paper. It is shown ... -
Collaborative Engine for Distributed Mechanical Design
(2002-01)Effective collaboration is essential for engineers at geographically dispersed locations to accomplish good design with less iteration. Over the last several years, more and more efforts have been put into such research ... -
The Complexity of Safety Stock Placement in General-Network Supply Chains
(2005-01)We consider the optimization problem of safety stock placement in a supply chain, as formulated in [1]. We prove that this problem is NP-Hard for supply chains modeled as general acyclic networks. Thus, we do not expect ... -
Computer-aided Tooling Design for Manufacturing Processes
(2003-01)Tooling design for manufacturing processes refers to direct tooling for making a part such as molds and dies for injection molded parts and metal stampings, or for supporting machining operations such as jigs and fixtures. ... -
Coordinating Inventory Control and Pricing Strategies with Random Demand and Fixed Ordering Cost: The Finite Horizon Case
(2005-01)We analyze a finite horizon, single product, periodic review model in which pricing and production/inventory decisions are made simultaneously. Demands in different periods are random variables that are independent of each ... -
Coordinating Inventory Control and Pricing Strategies with Random Demand and Fixed Ordering Cost: the Infinite Horizon Case
(2005-01)We analyze an infinite horizon, single product, periodic review model in which pricing and production/inventory decisions are made simultaneously. Demands in different periods are identically distributed random variables ... -
Cycle to Cycle Manufacturing Process Control
(2002-01)Most manufacturing processes produce parts that can only be correctly measured after the process cycle has been completed. Even if in-process measurement and control is possible, it is often too expensive or complex to ... -
