The holomorphic flow of the Riemann zeta function [PDF]

open access: yes, 2003
The flow of the Riemann zeta function, ś = ς(s), is considered, and phase portraits are presented. Attention is given to the characterization of the flow lines in the neighborhood of the first 500 zeros on the critical line.

Functional equations for zeta functions of groups and rings [PDF]

open access: yes, 2010
We introduce a new method to compute explicit formulae for various zeta functions associated to groups and rings. The specific form of these formulae enables us to deduce local functional equations. More precisely, we prove local functional equations for

Prediction of Zeta Potential for Tropical Peat in the presence of different Cations using Artificial Neural Networks

open access: yesInternational Journal of Electrochemical Science, 2011
Zeta potential (ζ) of the peat was measured by electrophoresis in the presence of different cations. Artificial neural networks (ANNs) were developed for the prediction of the ζ of peat in the presence of the cations at different pH values and ionic ...
