In this paper, we focus on surveying recent research results about the common process extraction methods in the field of machine learning and data mining. Not only the similarity measure between latent processes but also some classical higher-order statistic information based common process extraction algorithms are summarized. In addition, we propose a novel common process extraction method fr...

In this paper, various fast algorithms for linear blind source separation (BSS) are developed. The fast xed-point algorithm for independent component analysis 8, 6] is interpreted as an EM-algorithm with a modiication for accelerating the convergence rate which can otherwise be slow particularly in a low noise environment. The new point of view opens way for developing several new fast xed-poin...

In this paper, we compare the performance of five prominent neural or adaptive algorithms designed for Independent Component Analysis (ICA) and blind source separation (BSS). In the first part of the study, we use artificial data for comparing the accuracy, convergence speed, computational load, and other relevant properties of the algorithms. In the second part, the algorithms are applied to t...

In this paper, we introduce and study a new topology related to a self mapping on a nonempty set.Let X be a nonempty set and let f be a self mapping on X. Then the set of all invariant subsets ofX related to f, i.e. f := fA X : f(A) Ag P(X) is a topology on X. Among other things,we nd the smallest open sets contains a point x 2 X. Moreover, we find the relations between fand To f . For insta...

The Axial Separation Module (ASM), which separates whole-blood specimens serially in Axial Process Containers (APC), was evaluated for clinical performance at the University of Virginia Health Sciences Center (UVA HSC) in a community-based outpatient laboratory (North Ridge Clinic). We hypothesized that moving the task of blood separation to point of care would reduce specimen turnaround time w...

A micell-mediated phase separation method for preconcentration of ultra-trace quantities of mercury as a prior step to its determination by UV-Vis spectrophotometry has been developed. The method is based on Hg(II)-dithizone complex formation in alkaline aqueous solution, and extraction of this Hg(II)-dithizone secondary complex into the surfactant-rich phase of the non-ionic surfactant oct...

A variational technique is used to derive analytical expressions for the sensitivity of several geometric indicators of flow separation to steady actuation. Considering the boundary layer flow above a wall-mounted bump, the six following representative quantities are considered: the locations of the separation point and reattachment point connected by the separatrix, the separation angles at th...

in this study, different methods of separating of the microalgae from the culture medium as one of the most important and expensive steps in achieving commercial production of biodiesel from microalgae was investigated. electro coagulation-flotation (ecf) was preferred among these methods due to its process simplicity and capability to scale up. the effect of three parameters, i.e., initial ph,...

Measuring the relationship between any pair of variables is a rich and active area of research that is central to scientific practice. In contrast, characterizing the common information among any group of variables is typically a theoretical exercise with few practical methods for high-dimensional data. A promising solution would be a multivariate generalization of the famous Wyner common infor...
