An Application of Distributed Solid Modeling: Feature Recognition
(1994)
The availability of low-cost computational power is a driving force behind the growing sophistication of CAD software. Tools designed to reduce time-consuming build-test-redesign iterations are essential for increasing ...
Supervenient Hierarchies of Behaviors: Lessons Learned from a Vacuuming Robot
(1994)
In this paper we describe the use of behavior hierarchies based on ﲭerging two models of multi-layer architecture -- the supervenience model of [1] and the subsumption model of [4]. The behavior hierarchy approach allows ...
Robust Control of Set-Valued Discrete Time Dynamical Systems
(1994)
This paper presents results obtained for the robust control of discrete time dynamical systems. The problem is formulated and solved using dynamic programming. Both necessary and sufficient conditions in terms of (stationary ...
Fractal Geometry Applied to On-line Monitoring of Surface Finish
(1994)
Surface finish of machined parts determines the functionality of the product and also the machining requirements for making the parts. On-line monitoring of surface finish has been an active area of machining research. ...
Development of a Prototype System for On-Line Monitoring of Surface Roughness Using Fractal Geometry
(1994)
On-line measurement of surface roughness is an important element in a Computer Integrated Manufacturing (CIM) environment. Current methods of contact measurement are not suitable as they interfere with the machining process. ...
Analysis of the n-dimensional quadtree decomposition for arbitrary hyper-rectangles
(1994)
We give a closed-form expression for the average number of n- dimensional quadtree nodes (ieces' or locks') required by an n-dimensional hyper-rectangle aligned with the axes. Our formula includes as special cases the ...
Risk-Sensitive Optimal Control of Hidden Markov Models: A Case Study
(1994)
We consider a risk-sensitive optimal control problem for hidden Markov models (HMM). Building upon recent results by Baras, James and Elliott, we investigate the structure of risk-sensitive controllers for HMM, via an ...
Manufacturing Feature Instances: Which Ones to Recognize?
(1994)
Manufacturing features and feature-based representations have become an integral part of research on manufacturing systems, largely due to their ability to model correspondences between design information and manufacturing ...
Robust and Risk-Sensitive Output Feedback Control for Finite State Machines and Hidden Markov Models
(1994)
The purpose of this paper is to develop a framework for designing controllers for finite state systems which are robust with respect to uncertainties. A deterministic model for uncertainties is introduced, leading to a ...
Further Results on MAP Optimality and Strong Consistency of Certain Classes of Morphological Filters
(1994)
In two recent papers [1], [2], Sidiropoulos et al. have obtained statistical proofs of Maximum A Posteriori} (MAP) optimality and strong consistency of certain popular classes of Morphological filters, namely, Morphological ...
