This note describes a simple method for efficiently estimatingthe dominant eigenvalues and eigenvectors of the solution to a Lyapunovequation, without firstsolving the equation explicitly. The method isbased on the power method and matrix-vector multiplications and isparticularly suitable for problems where those multiplications can be doneefflciently, such as where the ...

original article   introduction: human errors are of the most important issues due to the technological advances in various work settings. in medical professions, including nursing, investigation of human errors would help to find out approaches for the identification and reduction of these errors. hence, the present study aimed to identify and assess nurses' errors in emergency ward of an educ...

Recent results in the area of language identification have shown a significant improvement over previous systems. In this paper, we evaluate the related problem of dialect identification using one of the techniques recently developed for language identification, the Gaussian mixture models with shifted-delta-cepstral features. The system shown is developed using the same methodology followed fo...

Due to the fact that the error surface of adaptive infinite impulse response (IIR) systems is generally nonlinear and multimodal, the conventional derivative based techniques fail when used in adaptive identification of such systems. In this case, global optimization techniques are required in order to avoid the local minima. Harmony search (HS), a musical inspired metaheuristic, is a recently ...

This paper describes the various frequency domain methods which may be used to analyze experiments data on the force experienced by a circular cylinder in wave and current to estimate drag and inertia coefficients for use in Morison’s equation. An additional approach, system identification techniques (SIT) is also introduced. A set of data obtained from experiments on heavily roughened circular...

Whilst Human Reliability Analysis (HRA) has been well-accepted and integrated into the safety management process in other industries, the application of such error analysis techniques to the problem of complication and reaction to treatment and the associated risks in healthcare is rare. Though the scarcity of HRA techniques in health-care is likely to be due in some part to the safety culture,...

Prediction error techniques for joint identification of parametric transfer functions and noise models from measured data are considered. The time domain and frequency domain prediction error methods are presented and compared and their close connection with corresponding maximum-likelihood method is explored. Conditions are established under which the two techniques are asymptotically equivalent.
