Facilitating Network Data Exploration with Query Previews: A Study of User Performance and Preference
(1998)
Current network data exploration systems which use command languages (e.g. SQL) or form fill-in interfaces fail to give users an indication of the distribution of data items. This leads many users to waste time posing ...
Evaluating Sheet Metal Nesting Decisions
(1998)
This paper describes models that estimate the cost and time of sheet metal punching when nesting (batching) orders. These models help decision-makers plan production and evaluate the impact of changing the nesting policy. ...
Discrete-Time Risk-Sensitive Filters with Non-Gaussian Initial Conditions and their Ergodic Properties
(1998)
In this paper, we study asymptotic stability properties ofrisk-sensitive filters with respect to their initial conditions. In particular, we consider a linear time-invariant system with initial conditionsthat are not ...
Risk-Sensitive and Minimax Control of Discrete-Time, Finite-State Markov Decision Processes
(1998)
This paper analyzes a connection between risk-sensitive and minimaxcriteria for discrete-time, finite-states Markov Decision Processes(MDPs). We synthesize optimal policies with respect to both criteria,both for finite ...
A Lyapunov Functional for the Cubic Nonlinearity Activator-Inhibitor Model Equation
(1998)
The cubic nonlinearity activator-inhibitor model equation is a simpleexample of a pattern-forming system for which strong mathematical resultscan be obtained. Basic properties of solutions and the derivation ofa Lyapunov ...
On a Reduced Load Equivalence under Heavy Tail Assumptions
(1998)
We propose a general framework for obtaining asymptotic distributional bounds on the stationary backlog <I> W<SUP>A<SUB>1</SUB>+A<SUB>2</SUB>,c</SUP></I> in a buffer fed by a combined fluid process <I>A<SUB>1</SUB>+A<SUB ...
A Framework for Routing and Congestion Control for Multicast Information Flows
(1998)
We propose a new multipurpose multicast routing and schedulingalgorithm (MMRS). The routing policy load balances amongstvarious possible routes between the source and the destinations,relying its decisions on the message ...
Logistic Mixtures of Generalized Linear Model Times Series
(1998)
In this dissertation we propose a class of time series models for mixture data. We call these logistic mixtures. In such models the mixture's component densities have a generalized linear model (GLM) form. The regime ...
Model Reduction for a Tungsten Chemical Vapor Deposition System
(1998)
A model of a tungsten chemical vapor deposition (CVD) system isdeveloped to study the CVD system thermal dynamics and wafer temperaturenonuniformities during a processing cycle. We develop a model for heattransfer in the ...
Integrated, Distributed Fault Management for Communication Networks
(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 ...
