In this work we present a comparative study, testing selected methods for clustering and classification of holter electrocardiogram (ECG). More specifically we focus on the task of discriminating between normal 'N' beats and premature ventricular 'V' beats. Some of the tested methods represent the state of the art in pattern analysis, while others are novel algorithms developed by us. All the algorithms were tested on the same datasets, namely the MIT-BIH and the AHA databases. The results for all the employed methods are compared and evaluated using the measures of sensitivity and specificity.

The objective of this research is to determine a near optimal fuel efficient control strategy for an electric propulsion space vehicle to attain a predefined velocity at the target. The control strategy is represented as a chromosome and micro genetic algorithms are used to find the best solution. The control strategy uses me space vehicle's reverse thrust and the sling effect caused by the Sun. Copyright - World Automation Congress (WAC) 2006.

One of the main challenges of any related paradigms in systems engineering is being able to handle complex systems under unforeseen uncertainties. A system may be called complex if its dimension (order) is too high and its model (if available) is nonlinear, interconnected, and information on the system is so uncertain that classical techniques cannot easily handle the problem. A system of systems (SoS) is a "super system," or an integration of complex systems coordinated together in such a way as to achieve a wider set of goals with possible higher significance such as global warming, Mars missions, air traffic control, global earth observation system, etc. Computational Intelligence or Soft Computing, a consortium of fuzzy logic (approximate reasoning), neuro-computing (learning), genetic algorithms and genetic programming (optimization), has proven to be a powerful set of tools for adding autonomy and semi-autonomy to many complex systems. For such systems the size of soft computing control architecture will be nearly infinite. In this presentation, paradigms using soft computing approaches are utilized to design autonomous controller with controller reuse for a number of space applications. The notion of adaptation in autonomous controller reuse can be handled via intelligent tools to add on additional capabilities in real-time scenarios. Learning from past experience is but one such scenario for the reuse of autonomous controllers. These applications include satellite array formations, robotic agents and the Virtual Laboratory (V-LAB®) for multi-physics modeling and simulation. A view of the future activities of the NASA JPL for space exploration will also be given. SoS concepts will be described and a few testbed cases will be introduced, including a robotic swarm with dynamic sensor networks for homeland security at UTSA ACE center. Some animated and experimental implementation movies will be shown.

In this paper, we propose an embedded multi-task scheduling system to make the wireless brain computer interface to real-time receive electroencephalogram signal more accurate. This method we propose also can increase the flexibility of the system. Base on the method, we can change the peripheral devices easily. And the tasks are taken as modules, so it also can increase the flexibility of system programs. The proposed system integrates electroencephalogram signal amplifier technique, wireless transmission technique, and embedded real-time system. The OMAP (Open Multimedia Architecture Platform) is used as a development platform and an embedded operating system is also used. © 2006 IEEE.

This paper considers the problem of guaranteed exponential stability of switched delay systems by using Lyapunov function method, Razumikhin technique. The scheme of average dwell time is introduced into the switched delay systems. Based on the scheme of average dwell time, sufficient conditions for exponential stability of switched delay systems are presented. For a certain class of switched delay systems, a lower bound on the average dwell time guaranteeing exponential stability can be explicitly calculated via the solutions of some linear matrix inequalities (LMIs). A numerical example is given to illustrate the effectiveness of the proposed method. ©2006 IEEE.

In this paper, we propose a cooperative control strategy for a group of robotic vehicles to achieve the specified task issued from a high-level astronaut command. The problem is mathematically formulated as designing the cooperative control for a general class of multiple-input-multiple-output (MIMO) dynamical systems in canonical form with arbitrary but finite relative degrees such that the outputs of the overall system converge to the explicitly given steady state. The proposed cooperative control for individual vehicle only need to use the sensed and communicated outputs information from its local neighboring vehicles. No fixed leader and time-invariant communication networks are assumed among vehicles. Particularly, a set of less-restrictive conditions on the connectivity of the sensor/communication networks are established, under which it is rigorously proven by using the newly found nice properties of the convergence of sequences of row stochastic matrices that the cooperative objective of the overall system can be achieved. Simulation results for a group of vehicles achieving a target and surrounding a specified object in formation are provided to support the proposed approach in this paper.
