ATM in Hybrid Networks

Baras, John S. (1996)

A discussion of the extensions or modifications required to integrate ATM into hybrid networks, i.e. seamlessly interconnected terrestrial and space, wireline and wireless networks will be presented. In this context, the ...

Robust Control of Set-Valued Discrete Time Dynamical Systems

Baras, John S.; Patel, N.S. (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 ...

Cues: File Subsystem Data Streams

Gupta, Sandeep; Baras, John S.; Kelley, Stephen; Roussopoulos, N. (1996)

We present a system call which enable directing high performance data transfers with in-kernel streams. The streams are defined and run using abstract data types called Cues, formed over the Unix file subsystem. The system ...

Integrated, Distributed Fault Management for Communication Networks

Baras, John S.; Li, Hongjun; Mykoniatis, G. (1998)

This report describes an integrated, distributed fault management (IDFM) system for communication networks. The architecture is based on a distributed intelligent agent paradigm, with probabilistic networks as the framework ...

Integrated Product and Process Design Environment Tool for Manufacturing T/R Modules

Karne, Ramesh K.; Lai, Hsing-Tsu; Dandekar, Swati V.; Baras, John S.; Ball, Michael O.; Bashyam, Sridhar; Trichur, Vinai S.; Karir, Manish; Kebede, Abraham; Williams, Jim (1997)

We present a decision making assistant tool for integrated product and process design environment for manufacturing applications. Specifically, we target microwave modules which use Electro-mechanical components and require ...

Hybrid Network Management

Baras, John S.; Ball, Michael O.; Karne, Ramesh K.; Whitefield, David; Kelley, Stephen; Jang, Kap D.; Plaisant, Catherine; Roussopoulos, Nick; Stathatos, Kostas; Vakhutinsky, Andrrew; Valluri, Jaibharat (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 ...

Reduced Complexity Output Feedback Nonlinear HControllers and Relation to Certainty Equivalence

Baras, John S.; Patel, N.S. (1995)

In this paper, we consider the problem of constructing reduced complexity controllers for output feedback nonlinear Hcontrol. We give sufficient conditions, under which the controllers so obtained, guarantee asymptotic ...

Robust and Risk-Sensitive Output Feedback Control for Finite State Machines and Hidden Markov Models

Baras, John S.; James, Matthew R. (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 ...

Robust H∞ Output Feedback Control of Bilinear Systems

Teolis, C.A.; Yuliar, S.; James, Matthew R.; Baras, John S. (1996)

The study of robust nonlinear control has attracted increasing interest over the last few years. Progress has been aided by the recent entension [FM91, Jam92] of the linear quadratic results [Jac73, Whi81] linking the ...

Estimation of Hidden Markov Models for Partially Observed Risk Sensitive Control Problems

Frankpitt, Bernard A.; Baras, John S. (1997)

We look at the problem of estimation for partially observed, risk-sensitive control problems with finite state, input and output sets, and receding horizon. We describe architectures for risk sensitive controllers, and ...
