The paper is devoted to the parameter identification of the axial dispersion model in the closed–open canal. It is oriented to the identification precision for the two variants of the flow model with various variance levels. The identification method is based on the transfer function application for the solution of given model PDE. When the impulse function g(t) is obtained, the characteristics...

This paper studies the problem of state regulation for uncertain state-space models. It formulates a new weighted game-type cost function with bounds on the sizes of the uncertainties in the data. The cost function is of independent interest in its own right and its optimal solution is shown to satisfy an orthogonality condition similar to least-squares designs. When used in the context of stat...

The weighted sum of squared differences cost function is often minimized to align two images with overlapping fields of view. If one image is shifted with respect to the other, the cost function can be written as a sum involving convolutions. This paper demonstrates that performing these convolutions in the frequency domain saves a significant amount of processing time when searching for a glob...

A popular technique for time delay estimation is to use an FIR #lter to model the time di-erence and the #lter weights are interpolated with a sinc function to obtain the delay estimate. However, the sinc interpolator requires a su/ciently long #lter length for accurate delay estimation. In this paper, we propose to process the #lter weights via a least-squares-based method in order to acquire ...

in this paper, we have examined abrupt changes in volatility of tepix index in tehran stock exchange during august 23, 2010 to june 12, 2014. applying the iterated cumulative sum of squares (icss) algorithm proposed by inclan and tiao (1994) and the modified version of this algorithm consisting kappa 1 and kappa 2 test statistics developed by sansó et al. (2004), we have specified that the dete...

This study draws on a comparative framework to evaluate the translation of political implications in three Persian translations of the novellaAnimal Farm (by George Orwell), using  Fairclough’scritical discourse analysis (CDA) model. The study regards political implications and ideologies as a mode of background knowledge shared by writers and audiences in the source language. Fairclough’s mode...

This chapter provides a tutorial introduction to gradientbased optical flow estimation. We discuss least-squares and robust estimators, iterative coarse-to-fine refinement, different forms of parametric motion models, different conservation assumptions, probabilistic formulations, and robust mixture models.

We consider issues related to the design and analysis of least-squares methods for the incompressible NavierStokes equations. An abstract framework which allows to treat a large class of methods is outlined and illustrated by means of several specific examples of least-squares methods.

A model-based least-squares algorithm with a time-varying forgetting factor is developed for leak detection in boiler steam-water systems. The algorithm has been tested using real industrial data from Syncrude Canada, and has proven to be effective in detection of boiler tube or steam leaks; proper implementation of the algorithm would lead to early leak warning, which is important in maintaini...
