In this paper, the problem of identifying stochastic linear discrete-time systems from noisy input/output data is addressed. The input noise is supposed to be white, while the output noise is assumed to be coloured. Some methods based on instrumental variable techniques are studied and compared to a least squares bias compensation scheme with the help of Monte Carlo simulations.

The errors–in–variables framework concerns static or dynamic systems whose input and output variables are affected by additive noise. Several estimation methods have been proposed for identifying dynamic errors–in– variables models. One of the more promising approaches is the so–called Frisch scheme. This report decribes three different estimation criteria within the Frisch context and compares...

The results of two free-recall learning experiments, in which the number and sequential combinations of input and output phases were systematically varied, indicated that (a) recall tests facilitate the overall immediate post-input recall approximately to the same extent as do the events occurring in input phases, (b) input and output events are approximately equally responsible for forgetting ...

This study was designed to find which one of the three different presentations, i.e. input, input-output, and output-input, will be more effective in Iranian EFL learners' vocabulary acquisitions. To this end, first 54 out of 64 female students, aged from 19 to 23 years, with an average of 21, were selected out of starter-level EFL learners at the University of Tarbiat Moalem in Bandar Abbas, I...

Active fault isolation of parametric faults in closed-loop MIMO systems are considered in this paper. The fault isolation consists of two steps. The first step is groupwise fault isolation. Here, a group of faults is isolated from other possible faults in the system. The group-wise fault isolation is based directly on the input/output signals applied for the fault detection. It is guaranteed th...

In this paper, a novel approach for finite-time stabilization of uncertain affine systems is proposed. In the proposed approach, a fast terminal sliding mode (FTSM) controller is designed, based on the input-output feedback linearization of the nonlinear system with considering its internal dynamics. One of the main advantages of the proposed approach is that only the outputs and external state...

introduction: due to increased costs of health sector, much effort has been done to compare the performance of hospitals and measure their efficiency in recent years. the purpose of this study was to evaluate the relative efficiency of public and private hospitals in qom during 2007 using data envelopment analysis (dea) approach. methods: this was an applied and analytic study. the study popula...
