A Case Study In Synchronous Parallel Discrete Event Simulation, José Miguel Alonso, José A.B Fortes
A Case Study In Synchronous Parallel Discrete Event Simulation, José Miguel Alonso, José A.B Fortes
Department of Electrical and Computer Engineering Technical Reports
This paper considers the suitability of SPED, a synchronous parallel discrete event simulator, for the study of message passing networks. The simulation algorithm is described, and its potential performance is assessed showing that, under some simplifying assumptions, SPED might offer speedups directly proportional to the number of processors used in the simulation. An implementation of SPED in a distributed memory parallel system is used to study a model of an interconnection network for a multicomputer. Experiments show that SPED performs nearly as expected, as long as the event density imposed on the LPs is above a certain threshold. If this …

Department of Electrical and Computer Engineering Technical Reports
A model of a message-passing network is used to analyze the behavior of three implementations of the Chandy-Misra-Bryant parallel simulation algorithm. The characteristics of the model, the organization of the logical processes that constitute the simulator and the characteristics of the host parallel computer have a definite influence on the achieved performance, measured in terms of speedup. Large, loaded models help CMB to synchronize with a minimum overhead, efficiently exploiting the available parallelism. Mapping several LPs onto each processor achieves a better use of the available processing power, because while a LP is blocked (synchronizing) others can use the CPU. …

Department of Electrical and Computer Engineering Technical Reports
Power system engineering largely focuses on steady state analysis. The main areas of power system engineering are power flow studies and fault studies - both steady state technologies. But the world is largely transient, and power systems are always subject to time varying and short lived signals. This technical report concerns several important topics in transient analyses of power systems. The leading chapter deals with a new analytical tool-wavelets-for power system transients. Flicker and electric are furnace transients are discussed in Chapters I1 and IV. Chapter 111 deals with transients from shunt capacitor switching. The concluding chapters deal with transformer …

On Nonlinear Circuit Components With N-Shaped Conductance Characteristics , Todd A. Wey, Lawrence L. Ogborn
Department of Electrical and Computer Engineering Technical Reports
Currently, three-terminal devices with N-shaped I-V characteristics are being fabricated for switching and multi-valued logic applications. The purpose of this study is to investigate switching speed improvements and potential problems of circuit designs employing these nonlinear devices. In this work, both two-terminal and three-terminal devices are analyzed. A design methodology is developed for a second-order twoterminal device circuit and a novel method of I-V characterization is presented. For the three-terminal device, a simple PSpice macromodel is developed and a new figure of merit for switching speed improvement is given. A practical chaotic synthesis method is proposed for this device in …

Bayes Error Estimation Using Local Metrics, Keinosuke Fukunaga, Sze-Po R. Hung
Department of Electrical and Computer Engineering Technical Reports
Bayes error estimation has long been an interesting topic in the pattern recognition area. For data with small dimensionality and large sample size, it is easy to estimate the upper and lower bounds of the Bayes error using global metrics in nonparametric classifiers. However, for the SAR (Synthetic Aperture Radar) data, the data dimensionality is very large (n=64x64=4,096) and the sample size is very small (Nz1,OOO). No conventional methods are able to estimate the Bayes error of the SAR data. Our solution to this problem is to hlly use the property that the intrinsic dimensionality of the SAR data is …

Statistical Estimation Of Combinational And Sequential Cmos Digital Circuit Activity Considering Uncertainty Of Gate Delay Models, Tan Li Chou, Kaushik Roy
Statistical Estimation Of Combinational And Sequential Cmos Digital Circuit Activity Considering Uncertainty Of Gate Delay Models, Tan Li Chou, Kaushik Roy
Department of Electrical and Computer Engineering Technical Reports
While estimating glitches or spurious transitions is challenge due to signal correlations, the random behavior of logic gate delays makes the estimation problem even more clifficult. In this paper, we present statistical estimation of signal activity at the internal and output nodes of combini3tional and sequential CMOS logic circuits considering uncertainty of gate delay models. The methodology is based on the stochastic models of logic signals and the probabilistic behavior of gate delays due to process variations, interconnect parmitics, etc. We propose a statistical technique of estimating average-case activity, which is flexible in adopting different delay models and variations and …
Nonlinear Modeling And Processing Of Speech With Applications To Speech Coding, Shan Lu, Peter C. Doerschuk
Nonlinear Modeling And Processing Of Speech With Applications To Speech Coding, Shan Lu, Peter C. Doerschuk
Department of Electrical and Computer Engineering Technical Reports
IN recent years there has been increasing interest in nonlinear speech modeling. In our approach, a speech signal is modeled as a sum of jointly amplitude (AM) and frequency (FM) modulated cosines with slowly-varying center ffrequencies. The key problem is to extract the center frequency and the amplitude and frequency modulations for each formant in the model from the measured speech signals. In this study, we describe the speech signal in terms of statistical models and apply statistical nonlinear filtering techniclues (Extended Kalman Filter) to estimate the amplitude and frequency. The Ahl and Fbl signals are estimated for all the …

Markuv random fields (MRF) have proven useful for modeling the a priori information in Bayesia.n tomographic reconstruction problems. However, optimal parameter estimation of the MRF model remains a difficult problem due to the intractable nature of the partition function. In this report, we propose a fast parameter estimation scheme to obtain optimal estimates of the free parameters associated with a general MRF model formulation. In particular, for the generalized Gaussian MRF (GGMRF) case, we show that the ML estimate of the temperature T has a simple closed form solution. We present an efficient scheme for the ML estimate of the …
