Tung Ouyang, A. Nilsson
Analyzes the performance of an output-buffered asynchronous transfer mode service multiplexer (ATM-SMX) in the North Carolina Information Highway (NCIH). The ATM-SMX is modeled as a discrete-time finite-buffer single-server queueing system, where two types of traffic represent the inputs of the multiplexer: (1) nonreal-time loss-sensitive traffic; and (2) real-time loss-insensitive traffic. The authors assume that there are N identical type 1 sources each modeled as a Bernoulli process. The authors also assume that there is a single type 2 source modeled as a periodic batch arrival where the batch site follows a general distribution. All the slow-speed inputs of the ATM-SMX are multiplexed onto a single high-speed output link, and the service rate is constant. The authors adopt a scheduling policy which suits the characteristics of these two types of traffic. An exact analysis is developed to obtain the waiting time distributions and cell loss probabilities for both types of traffic.

The paper introduces object-oriented large-grain data flow model and a parallelizing translator for the model. We design an efficient program partitioning algorithm based on objects for distributed system. Program restructuring according to the parallel model is automatically implemented by the translator.

This paper explains the implementation of a real time bi-target tracking using both acoustic and video data. We show how the cooperation of highly heterogeneous sensors may improve the overall efficiency. These data are filtered using Kalman filtering techniques. We send reconfiguration orders to the actuators for an optimal new data sampling. The observed scene raises some classical control problems like the partial observability conditions, the unpredictable behaviors for the different components of the world because of the limited a priori knowledge and the synchronisation of the data.

It is shown that complete design for a multivariable plant with unstructured additive uncertainty requires conforming of the plant model and controller, i.e. minimization of model uncertainty bound rated to the uncertainty bound, allowed by the controller for particular design specifications. A sample design procedure is developed using a SVD controller and quasi-normalization technique in order to re-solve a DC/AC convertor robust control problem.

Presents modified least loaded routing (MLLR), a routing policy where no preference is given to the direct single link path but rather the first choice path is chosen statistically based on the results of an optimization problem. The authors calculate shadow prices for MLLR using the blocking probability obtained from a fixed point performance evaluation algorithm. Numerical results comparing performance of LLR and MLLR in, terms of blocking probability are introduced. As an application, the authors formulate and solve a nonlinear constrained optimization problem to calculate the load sharing coefficients that result in a maximum network rate of return for fixed levels of OD pair blocking probabilities.

A SGML markup system is presented. One major obstacle for the SGML to gain more application is the prohibitively high cost of the markup process. The system the authors present adopts an incremental design approach. This approach helps to "divide and conquer" each specific problem encountered during the markup process and ensures that the system converges to a almost-fully automated markup system. The major software components of the system are described. Some selective algorithms are also introduced.

There has been significant interest in general classes of power electronic-based active power conditioners such as static condensers and dynamic voltage restorers. These systems are discussed in this paper with a focus on the inverter output stage. The inverters considered include conventional six- and twelve-pulse square wave, pulse-width modulated, and multi-level inverters. Current- and voltage-controlled inverters are considered where appropriate. Each of these inverter topologies has been successfully applied to a number of applications such as adjustable-speed motor drives and static VAr compensators but only limited information is available concerning the use of various topologies with active power conditioning equipment. This paper is intended to assimilate the information that is available in a convenient manner so as to provide the basis for continued research in this area.

This paper discusses a method, based on complete linearization, combining a nonlinear state observer design for nonlinear system. By applying the scheme to a polymeric reaction process, the simulation results show that it has not only good tracking ability and convergence but also better parameter robustness.

The design of an optimal MIMO PI-lead controller is described for linear, time-invariant systems. The authors consider the linear quadratic regulator (LQR) design framework as a means of optimally selecting the gains of the controller. Therefore, the controller is designed by solving a steady state algebraic Riccati equation. The performance between the PID and optimal PI-lead controllers is illustrated and compared through an example. Simulations and implementations of the controllers are done using the MATLAB and SIMULINK software packages.

Industries desire that each newcomer comes up the learning curve much faster than the previous one. They can help make this difference by partnership with educational institutions and universities, and taking advantage of the power of diversity these can provide. Acceleration of innovative ideas and production requires state of the art technologies and closer collaboration between academician, government and the private sector. It requires all engineering disciplines work effectively and achieve excellence in "doing it right for the first time". The ability to reach these goals will determine the next generation of winners and losers. This paper describes the necessary steps to implement all cross-functional cooperation with schools and industries. Specific examples are used to point out educational program enhancement, to reduce research expenditure, unite a broad range of engineering disciplines, to manufacture cost effective reliable products and put them in the market on time.
