the main aim of this research is to determine optimal leaching conditions; eh, ph and complexing agent concentrations, for recovery of copper from hydroxide sludges such as those produced by electroplating shops, metal finishers, treatment of acid mine drainage, and industrial wastewater in general. this has been preceded by a theoretical approach and numerical and computer calculation. potenti...

advanced technologies in molecular biology and modern experimental biophysics heavily rely not only on the knowledge of structure of essential proteins but also on their structural dynamics. the function of these bimolecular systems and the pathways along which the biological phenomena take place can be determined based on the knowledge of the molecular structure and behavior. as such, the simp...

Sparse tensor best rank-1 approximation (BR1Approx), which is a sparsity generalization of the dense BR1Approx, and higher-order extension sparse matrix one most important problems in decomposition related arising from statistics machine learning. By exploiting multilinearity as well structure problem, four polynomial-time algorithms are proposed, easily implemented, low computational complexit...

Abstract The paper proposes a computational method to study and test the relationship between shape performance for built environment, sustaining use of smart geometry support design operation. A comprehensive working principles hyperboloidical cooling tower is presented. case in Marghera (Venice), 1938 explored.

in descriptive statistics, there are two computational algorithms for determining the variance s2, of a set of observations : algorithm 1: s2= - , algorithm 2: s2= , where . it is interesting to discuss, which of the above formulas is numerically more trustworthy in machine numbers sets. i this paper, based on total effect of rounding error, we prove that the second algorithm is better than ...

the place of a topic like ‘procedures for developing religiosity’, as a novel and innovative topic, seems to have been standing empty beside topic like ‘origins of religiosity’, and ‘the origin of religion’. the present article, after describing the content, use, and requirements of the topic under investigation, deals with introducing and categorizing paradigms of religiosity. in order to come...

The classical non-recursive methods to estimate unknown parameters of the model, such as the maximum likelihood method, the method of least squares etc. eventually require maximization procedures. These methods are often difficult to implement, especially for non i.i.d. models. If for every sample size n, when new data are acquired, an estimator has to be computed afresh, and if a numerical met...

The current protocol for image-guidance in liver surgeries involves rigid registration algorithm. Systematic studies have shown that the liver can deform up to 2cms during surgeries thereby compromising the accuracy of the surgical navigation systems. Compensating for intraoperative deformations using computational models has shown promising results. In this work, we follow up the initial rigid...
