The Use of Behavior Hierarchies for Controlling a Vision-Based Space Teleoperation Robot
(1996)
In this thesis I describe the use of behavior hierarchies based on ﲭerging two models of multi-layer architecture --- the supervenience model of [18] and the subsumption model of [6]. The behavior hierarchy approach allows ...
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. ...
Improving the Efficiency of Limited-Memory Heuristic Search
(1995)
This paper describes a new admissible tree search algorithm called Iterative Threshold Search (ITS). ITS can be viewed as a much-simplified version of MA*[2], and a generalized version of MREC [15]. ITS's node selection ...
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 ...
Robust Control of Set-Valued Discrete Time Dynamical Systems
(1995)
This thesis deals with the robust control of nonlinear systems subject to persistent bounded non-additive disturbances. Such disturbances could be due to exogenous signals, or internal to the system as in the case of ...
Fractal Modeling and Segmentation for the Enhancement of Microcalcifications in Digital Mammograms
(1996)
The objective of this research is to model the mammographic parenchymal, ductal patterns and enhance the microcalcifications using deterministic fractal approach. According to the theory of deterministic fractal geometry, ...
Fast Digital Locally Monotonic Regression
(1995)
In [1], Restrepo and Bovik developed an elegant mathematical framework in which they studied locally monotonic regressions in RN . The drawback is that the complexity of their algorithms is exponential in N. In this paper, ...
Integrated Manufacturing Facility Design
(1995)
This dissertation addresses for the first time the integrated problem of designing the manufacturing shop layout concurrently with its material handling system. Specifically, this study provides a method to derive shop ...
Hybrid Network Management
(1996)
We describe our collaborative efforts towards the design and implementation of a next generation integrated network management system for hybrid network (INMS/HN). We describe the overall software architecture of the system ...
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 ...
