An inclusion principle for discrete-event and hybrid systems
(IEEE, 1997)Hybrid systems, which consist of continuous-state and discrete-state parts are considered. It is assumed that the discrete-state part of the system is event-driven. Inclusion and extension principles are first defined for ... -
Integrated routing and flow control in highways
(IEEE, 1997)A control algorithm which integrates routing and flow control in highways is discussed. The algorithm is based on a congestion measure. -
A statistical approach to determine the neighborhood function and learning rate in Self-Organizing Maps
(Springer-Verlag Singapore Pte LTD, 1998)The problem of choosing the neighborhood function and learning rate in Kohonen's Self-Organizing Map (SOM) is generally application dependent, empirical and difficult to analyze. In this paper, a new approach based on the ... -
A new approach to mathematical water quality modeling in reservoirs: Neural networks
(Wiley-V C H Verlag GMBH, 1998)Neural Networks are becoming more and more valuable tools for system modeling and function approximation as computing power of microcomputers increase. Modeling of complex ecological systems such as reservoir limnology is ... -
On rate-based congestion control in high speed networks: Design of an H? based flow controller for single bottleneck
(1998)Typical congestion control algorithms for high speed networks include local flow controllers at the bottleneck nodes. In this paper an H? based controller is developed for rate feedback in a single bottleneck network. The ... -
Linear discrete-event systems and robust servomechanism problem
(IEEE, 1998)Linear discrete-event systems are studied. Reachability, observability, controllability, constructibility, stabilizability and detectability of such systems are investigated. Stability of linear discrete-event systems is ... -
Downhill walk from the top of a hill by evolutionary programming
(IEEE Computer Society, 1999)When we search for an infinitely large number of solutions by evolutionary algorithms, it is helpful to learn the topology of the fitness landscape to know whether the solutions we obtained are representative samples of ... -
A decentralized control approach for transportation networks
(Pergamon Press LTD, 1999)A decentralized control approach for transportation networks to prevent traffic congestion is presented. The approach was developed by considering flow control and routing control together. The control algorithm is based ... -
Reliable matching and scheduling of precedence-constrained tasks in heterogeneous distributed computing
(Institute of Electrical and Electronics Engineers Inc., 2000)In this paper, two cost functions that can be incorporated into a matching and scheduling algorithm for tasks with precedence constraints are introduced to enable the algorithm to consider the reliability of different ... -
Optimal and suboptimal reliable scheduling of precedence-constrained tasks in heterogeneous distributed computing
(Institute of Electrical and Electronics Engineers Inc., 2000)This paper introduces algorithms which can produce both optimal and suboptimal task assignments to minimize the probability of failure of an application executing on a heterogeneous distributed computing system. A cost ... -
Robust rate-based flow controllers for high-speed networks: The case of uncertain time-varying multiple time-delays
(IEEE, 2000)An H-infinity based robust controller is designed for a rate-feedback flow-control problem in single-bottleneck data-communication networks. The controller is robust to uncertain time-varying multiple time-delays in different ... -
Comparison of H? and µ-synthesis based flow controllers for high-speed networks with multiple time delays
(2001)A flow controller design approach based on µ-synthesis is proposed. The performances of the resulting controllers and the H? controllers designed based on an approach proposed earlier, are compared. -
Trading off execution time for reliability in scheduling precedence-constrained tasks in heterogeneous computing
(Institute of Electrical and Electronics Engineers Inc., 2001)This paper investigates the problem of matching and scheduling of an application, which is composed of tasks with precedence constraints, to minimize both execution time and probability of failure of the application in a ... -
Stochastic scheduling of a meta-task in heterogeneous distributed computing
(Institute of Electrical and Electronics Engineers Inc., 2001)The fact that the scheduling problem is NP-complete has motivated the development of many heuristic scheduling algorithms. These heuristic algorithms often neglect the stochastic nature of tasks' execution times. Contrary ... -
A solution to the robust flow control problem for networks with multiple bottlenecks
(IEEE, 2001)The flow control problem in multi-bottleneck networks is considered. An optimization problem is formulated in order to design decentralized controllers which are robust to time-varying uncertain multiple time-delays. It ...
