Analytic evaluation of contention protocols used in distributed real-time systems
(Kluwer Academic Publishers; Springer Science+Business Media, 1995-07)
The probability of a station failing to deliver packets before their deadlines, called the probability of dynamic failure, P dyn , is an important measure for the communication subsystem of a distributed real-time system. ...
Toward a theory of honesty and trust among communicating autonomous agents
(Kluwer Academic Publishers; Springer Science+Business Media, 1993-09)
This article outlines, through a number of examples, a method that can be used by autonomous agents to decide among potential messages to send to other agents, without having to assume that a message must be truthful and ...
Diversity as a policy goal: The case of television
(Kluwer Academic Publishers; Springer Science+Business Media, 1978-06)
Diversity in communications is most appropriately understood as a free flow of ideas. In order to implement diversity, a comprehensive model of the communication process must be used for policy research, so that the various ...
The nature of middle school learners' science content understandings with the use of on-line resources
(Wiley Subscription Services, Inc., A Wiley Company, 2003-03)
Early research on using the World Wide Web indicated that middle school students did not explore much and used Web tools naively. In response to these challenges, an on-line research engine, Artemis, was designed to provide ...
Runtime monitoring of timing constraints in distributed real-time systems
(Kluwer Academic Publishers; Springer Science+Business Media, 1994-11)
Embedded real-time systems often operate under strict timing and dependability constraints. To ensure responsiveness, these systems must be able to provide the expected services in a timely manner even in the presence of ...
Feedback stabilization of control systems described by a class of nonlinear differential-algebraic equations
(Elsevier, 1990-07)
A theoretical framework for the stabilization of control systems defined by a class of nonlinear differential-algebraic equations is established. Assumptions are stated which guarantee that the nonlinear differential-algebaric ...
Promoting understanding of chemical representations: Students' use of a visualization tool in the classroom
(John Wiley & Sons, Inc., 2001-09)
Many students have difficulty learning symbolic and molecular representations of chemistry. This study investigated how students developed an understanding of chemical representations with the aid of a computer-based ...
Rate distortion lower bound for a special class of nonlinear estimation problems
(Elsevier, 1989-04)
A rate distortion lower bound of minimum mean square error is presented for a special class of discrete time nonlinear filtering problems which have measurements that can be expressed as a memoryless nonlinear function of ...
Carbon dioxide from fossil fuels : Adapting to uncertainty
(Elsevier, 1980-12)
If present scientific information is reasonable, the world is likely to experience noticeable global warming by the beginning of the next century if high annual growth rates of fossil fuel energy use continue. Only with ...
Queueing Networks of Random Link Topology: Stationary Dynamics of Maximal Throughput Schedules
(Kluwer Academic Publishers; Springer Science + Business Media, Inc., 2005-05)
In this paper, we study the stationary dynamics of a processing system comprised of several parallel queues and a single server of constant rate. The connectivity of the server to each queue is randomly modulated, taking ...
