A Feature Based Approach to Automated Design of Multi-Piece Sacrificial Molds
(2000)
This report describes a feature-based approach to automated design of multi-piece sacrificial molds. We use multi-piece sacrificial molds to create complex 3D polymer/ceramic parts. Multi-piece molds refer to molds that ...
Selecting Flat End Mills for 2-1/2D Milling Operations
(2000)
The size of milling cutter significantly affects the machining time. Therefore, in order to perform milling operations efficiently, we need to select a set of milling cutters with optimal sizes. It is difficult for human ...
Fast Evaluation of Demagnetizing Field in Three Dimensional Micromagnetics using Multipole Approximation
(2000)
Computational micromagnetics in three dimensions is of increasing interest with the development of magnetostrictive sensors andactuators. In solving the Landau-Lifshitz-Gilbert (LLG) equation, the governing equation of ...
A Geometric Algorithm for Finding the Largest Milling Cutter
(2000)
In this paper, we describe a new geometric algorithm to determine the largest feasible cutter size for2-D milling operations to be performed using a single cutter. In particular:<p>1. We give a general definition of the ...
Stochastic Approximation and Optimization for Markov Chains
(2000)
We study the convergence properties of the projected stochasticapproximation (SA) algorithm which may be used to find the root of an unknown steady state function of a parameterized family of Markov chains. The analysis ...
Computing Balanced Realizations for Nonlinear Systems
(2000)
This paper addresses the problem of computability pertaining to the Scherpen(1994) theory and procedure for balancing of nonlinear systems. In contrastto Moore's (1981) balancing method for linear systems, the Scherpen ...
Computational Micromagnetics for Magnetostrictive Actuators
(2000)
Computational micromagnetics plays an important role in design and control of magnetostrictive actuators. A systematic approach to calculate magnetic dynamics and magnetostriction is presented. A finite difference method ...
A Hierarchical Structure For Finite Horizon Dynamic Programming Problems
(2000)
In dynamic programming (Markov decision) problems, hierarchicalstructure (aggregation) is usually used to simplify computation. Most research on aggregation ofMarkov decision problems is limited to the infinite horizon ...
The MDLe Engine -- A Software Tool for Hybrid Motion Control
(2000)
One of the important but often overlooked practical challenges in motion control for robotics and other autonomous machines has to do with the implementation of theoretical tools into software that will allow the system ...
Comparing Gradient Estimation Methods Applied to Stochastic Manufacturing Systems
(2000)
This paper compares two gradient estimation methods that can be usedfor estimating the sensitivities of output metrics with respectto the input parameters of a stochastic manufacturing system.A brief description of the ...
