We develop a new traffic model derived from the arrival processes of the type M/G//spl infin/. This modeling method not only provides us an explicit and analytical expression for the self-similar traffic processes, but also sets up a connection between the two most popular self-similar processes. This model has a structure similar to that of a fractional ARIMA, with a driven process of fBm (fractional Brownian motion). But the coefficients of the fBm are derived from the Pareto distribution of the active periods of the arrival process. We also derive an explicit buffer level equation based on the proposed traffic model, which matches Norros' (1994) storage model. So this method can be also served as a verification of Norros' assumptions. The queueing behavior of a single server to self-similar input can be analytically investigated with the proposed equation. The effectiveness of these methods has been demonstrated by some practical applications.","PeriodicalId":176763,"journal":{"name":"1999 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing (PACRIM 1999).

For example, formal system development can aid the development of correct systems. Formal specification and verification techniques have been extensively investigated, but these techniques have generally not addressed the requirement of distributed multimedia computing. The central issue in multimedia is dealing with real-time. In particular, there is a need for software development techniques that support the specification and verification of real-time properties. In this paper, we propose a new approach to the formal specification and verification of distributed multimedia computing. This new approach is based on the extension of LOTOS to incorporate timing in it. Thus, succinct expressions of communicating concurrent processes can be made. Similarly, the emphasis on non-determinism in process algebraic techniques facilitates abstract specification, hiding implementation details. Furthermore, rich and tractable mathematical models of the semantics of process algebra have been developed. The key characteristic of the new approach lies in the specification of behavior, requirements and different types of time in a specification.","PeriodicalId":176763,"journal":{"name":"1999 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing (PACRIM 1999).

Although molecular phylogenetic trees are fundamental data structures in evolutionary analysis, no database system is available that can match trees in the database against a user-supplied tree by comparing tree structures. In this paper, we propose a phylogenetic tree database system with a retrieval function that matches trees having similar structure. The tree data stored in the database are transformed from document images published in biological journals using a pattern-recognition program developed by us. To retrieve phylogenetic trees from the database according to their structures, we propose a method of determining the structural similarity between trees that is based on the split distance method. Our structural similarity measure shows high correlation with the log-likelihood difference that is widely used for comparing phylogenetic trees, and the computation time of our measure is much shorter than that of the log-likelihood difference, which relies on sequence comparison.","PeriodicalId":176763,"journal":{"name":"1999 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing (PACRIM 1999).

The interconnection network in such systems transfers cache line messages between processor caches and memory modules on read and write misses. The major component of the miss penalty, for the case of large systems, is the network delay. Using only a relatively small number of node parameters (cache miss rate, cache line length, number of outstanding transfer requests allowed, memory access time, proportion of Reads to Writes), along with the bandwidth and delay versus throughput characteristics of the network, the analytic model is shown to give good estimates of the processor utilization values derived from an independent detailed simulation study. In particular, for multiprocessor sizes of 72 and 108 nodes, and for variations in the node parameters, the processor utilization values determined by the analytic model are within 10% of the simulation results. Processor utilizations vary from 0.41 to 0.88. The interconnection network involved is a hierarchical slotted-ring system.","PeriodicalId":176763,"journal":{"name":"1999 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing (PACRIM 1999).
