Robust Matched Filters for Optical Receivers.
(1987)
The problem of designing optical receivers that are robust against uncertainty in the statistics of the observation process in photodetection is investigated. In particular, a modification in the design of the post-detection ...
Setpoint Tracking vs. Disturbance Rejection for Stable and Unstable Processes.
(1987)
The issue of controller tuning for setpoint tracking versus disturbance rejection has been discussed in the process control literature for many years. The purpose of this paper is to review and explain the problem and to ...
Some Solutions to Problems in Depth Vision from Differential Geometry and Deconvolution Methods
(1987)
Two distinct parts are presented. The first part is an application of manifold theory and geometry to mathematical modeling problems in depth vision. the second part is an application of deconvolution methods to the problem ...
Polymerization of Olefins through Heterogeneous Catalysis. IV. Modeling of Heat and Mass Transfer Resistance in the Polymer Particle Boundary Layer.
(1987)
Propylene and ethylene polymerization in liquid and gss media are described by a multigrain particle model. External boundary layer heat and mass transfer effects are investigated for various catalysts and operating ...
On the Stability of Polynomials with Uncoupled Perturbations in the Coefficients of Even and Odd Powers.
(1987)
In this note, we present some results concerning the stability (in Hurwitz' sense) of a family of polynomials with even and odd coefficients subject to uncoupled perturbations. It is shown that the stability of an appropriate ...
Expert Database Systems: Efficient Support for Engineering Environments.
(1987)
Manufacturing and Engineering processes use both large scale data and knowledge bases, and the use of expert systems in such environments has become a necessity. Expert Database Systems have evolved from conventional ...
Expected Forward Progress and Throughput of Multi-Hop Frequency- Hopped Spread-Spectrum Networks.
(1987)
Secondary multiple-access interference processes are characterized for multi-hop packet radio networks, in which users are assumed to be Poisson-distributed in the plane and to use frequency-hopped spread-spectrum signaling ...
An Expert Systems Approach to Integrating Product Design and Manufacturing Execution Modules.
(1987)
To build an interface between product design and manufacturing execution modules is the first phase to achieving Computer Integrated Manufacturing for the factory of the future. A model of the Computer Aided Design ...
Control System Design for a Flexible Arm.
(1987)
In this thesis, we study the problem of real-time control of a flexible arm. We have investigated techniques for compensating the effects of friction and ripple torque. New software was written to use a Metrabyte Data ...
On Routing Two-Terminal Nets in the Presence of Obstacles.
(1987)
We consider the problem of routing k two-terminal nets in the presence of obstacles in two models: the standard two-layer model and the knock-knee model. Determining routability is known to be NP-complete for arbitrary k. ...
