    A recognized advantage associated with the use a Smith chart is that it obviates the employment of complex algebra in solving transmission line problems. The paper focuses on combining the power of the PC, with its visual aesthetics, speed and accuracy, for the purpose of familiarizing students in the use of the Smith's graphical transmission line calculator. The demo version of the PC Smith chart... View full abstract»

    An approach based on an algebraic Riccati equation for designing an observer-based H∞ reduced-order controller is provided. The advantage of this approach is that through pole-zero cancellation, we only need to solve one algebraic Riccati equation during the design process. The scheme can guarantee that the closed-loop system is stable and the closed-loop transfer function satisfi... View full abstract»

    Discrete/continuous (D/C) control is a natural generalization of conventional discrete-time control in which the control is strategically varied with time, in a specified continuous manner, between each consecutive pair of sample-times. In series of previous papers by the authors (1996, 1999, 2000) the LQR optimization of discrete/continuous control variations that are restricted to be -linear-in-... View full abstract»

    This paper is a survey of recent literature in adaptive flight control. Although there are many published articles using classical control techniques, the trend appears to be toward using intelligent control techniques, particularly neural networks based methods. The survey is not presented in a chronological order, and it is not claimed to be exhaustive. In this rapidly progressing field, the onl... View full abstract»

    In automatic target recognition (ATR) systems there are advantages to developing classifiers based on a portion of the signal. A partitioning technique is introduced in this paper that allows rough set theory to be applied to real-world size problems. Rough set theory (RST) is an emerging concept for determining features and then classifiers from a training data set. RST guarantees that once the d... View full abstract»

    A definition of poles is presented for continuous-time, linear, time-varying systems. For a linear, time-varying state equation, a set of time-varying poles defines a stability-preserving variable change relating the original state equation to an upper triangular state equation. This definition is shown to be a generalization of existing definitions of poles of a linear, time-varying system and is... View full abstract»

    The goal of this research is to develop a magnetically suspended momentum wheel capable of actively reducing imbalance vibrations. Typically, this would require two radial magnetic bearings with separately energized x and y-axes and one axial bearing. In this system, however, the radial and axial functions were combined into a single design for a more compact and elegant package. One downside of t... View full abstract»

    With the growing threat of abuse of network resources, it becomes increasingly important to be able to detect malformed packets on a network and estimate the damage they fan cause. In this paper, we collect and analyze all of the IP and TCP packets seen on a network that either violate existing standards or should not appear in modern internets. Our goal is to determine what these suspicions packe... View full abstract»

    Spectroscopic data are prone to instrumentation noise. Traditional methods for noise removal require a priori knowledge of the spectra. One does not have such information when analyzing chemical components in the environment. In this paper, parametric methods for performing spectral analysis of spectroscopic data are investigated. The corresponding model parameters used to describe the spectrum as... View full abstract»

    This paper studies quantitatively the relative merits of commonly used linear models in steady state power system analysis. The `DC model' assumes negligible resistances and flat voltage profiles, and relates the bus phase angles to real power injections. A new linear model which accounts for the voltage and reactive power flows is developed and used in the comparative study. The first iteration o... View full abstract»
