This paper addresses the problem of designing a data-dimension reducing transformation matrix, to be used for beamspace direction-of-arrival (DOA) estimation. The design of the transformation matrix is based on numerical optimization techniques. The criteria to be satissed is to retain as much as possible of the achievable, optimal estimation accuracy using the non-reduced data-sizes, while als...

A direct method is developed that reduces a polynomial system matrix describing a discrete linear repetitive process to a 2-D singular state-space form such that all the relevant properties, including the zero structure of the system matrix, are retained. It is shown that the transformation linking the original polynomial system matrix with its associated 2-D singular form is zero coprime syste...

In many applications, one is required to estimate the projective transformation between two sets of points, which is also known as collineation or homography. This report presents a number of techniques for this purpose.

Abstract: Besides different definitions, in this work is given the so called transformation matrix, which maps the given index space in another index space. Transformation used in this new index space reduces the number of processing elements in the array. We illustrate all possible instances of transformation matrices and we show the importance of using the transformation matrix by comparing t...

Electronic business provides many benefits to organizations that embrace on it. It is true that ebusiness improve business processes, integrate business processes and its corresponding value chain, give speed to internal and external organizational activities etc, but it poses the greatest challenge to today’s organizations to transform their traditional businesses into electronic business. To ...

in this paper a novel process monitoring scheme for reducing the type і and type іі error rates in the monitoring phase is proposed. first, the proposed approach uses an augmented data matrix to implement the process dynamic. then, we apply independent component analysis (ica) transformation to the augmented data matrix, and eliminate the outliers using the local outlier factor (lof) algorithm....

Incorporation of copper species into silica matrix was performed by the sol-gel method. Copper ions and copper particles were doped using two different copper sources; Cu(NO3)2.3H2O and copper particles chemically synthesized.The particles of copper metallic, cuprous and cupric oxide were prepared and the synthesis and characterizations of copper species were compared together. On the other han...

This article treats data reduction in array processing for the spatially colored noise case. The purpose is to reduce the computational complexity of the applied signal processing algorithms by mapping the data into a space of lower dimension by means of a linear transformation. We discuss ways to implement the transformation and show that it suffices to estimate the array covariance matrix ins...
