In this paper we make a first attempt at understanding how to build an optimal approximate normal factor analysis model. The criterion we have chosen to evaluate the distance between different models is the Idivergence between the corresponding normal laws. The algorithm that we propose for the construction of the best approximation is of an the alternating minimization kind.

Independent component analysis (ICA) is a statistical method for transforming an observed multidimensional random vector into components that are statistically as independent from each other as possible. In this paper, the linear version of the ICA problem is approached from an information-theoretic viewpoint, using Comon's framework of minimizing mutual information of the components. Using max...

The use of cutting fluid in manufacturing industries has now become more problematic due to environmental pollution and health related problems of employees. Also the minimization of cutting fluid leads to the saving of lubricant cost and cleaning time of machine, tool and work-piece. The concept of minimum Quantity Lubrication (MQL) has come in to practice since a decade ago in order to overco...

In this paper, an alternative approach is provided in the well-posedness analysis of elliptic variational–hemivariational inequalities real Hilbert spaces. This includes unique solvability and continuous dependence solution on data. most existing literature inequalities, results are obtained by using arguments surjectivity for pseudomonotone multivalued operators, combined with additional compa...

Pneumonia is one of the significant causes death in developing countries, including Indonesia. As capital West Java, Bandung cities with highest pneumonia cases this province. The objective study was to conduct cost-minimization analysis treatment Indonesia by using private hospitals as a reference case. use cefuroxime and ceftizoxime considered adult hospitalized patients. In addition, ampicil...
