“…Using the procedure described by Alfaro based on the kinetic model developed by Caceres et al, the corrosion parameters from potentiodynamic curves were obtained by using this model. The total current density ( i t ) is considered as the algebraic sum of the anodic ( i a ) and cathodic current ( i c ) (Equations .…”

“…The mathematical procedure is described by Alfaro. [20] Figure 3 shows an example of the correlation of polarization curves for Zr and anodized Zr (Zr-NT) in Afnor solution (oxygen concentration = 9.35 mg L −1 ) with the kinetic model by using excel spreadsheets to predict the total current density. The corrosion and correlation parameters for Zr and Zr-NT are presented in Table 1 and respectively, in Table 2.…”

The aim of this study is to investigate the corrosion behavior of anodized Zr in oral cavity environment simulated by Afnor saliva as a function of the amount of dissolved oxygen. For comparison, non treated Zr was also investigated in the same conditions. In order to study the corrosion behavior at open circuit potential versus time, cyclic potentiodynamic polarization (CPP) and electrochemical impedance spectroscopy (EIS) were performed. scanning electron microscopy (SEM) with energy dispersive X‐ray (EDX) imaging was used to observe the morphology and topography of the modified electrodes. Experimental data show that the decrease of oxygen concentration leads to the inhibition of the corrosion process for non treated Zr and Zr covered with nanotubes. A range of electrochemical stability of zirconia nanotubes in artificial Afnor saliva as a function of oxygen content in simulated oral cavity environment was established.

“…As it has now become clear that by checking the long list of statistical application software and list of programs for developing such applications, a single point brightens up the argument in which all those applications require an environment for data processing. Microsoft Excel similar to Weka is not far from this end user interaction between machines and human cognitive thinking in the way of providing simulations [19,20].…”

“…Few institutions have developed a series of plugins to expand the power of this application so to provide more tools to data scientist and so to work with larger projects. A good list of such add-ins can be found at VeryViz website [21], such as FRED's data resource provider add-ins at [22], DataForecasting at [23] and SimTools and FormList at [24]. Few of those plug-ins are not free and they can be obtained with a payment paid to those institutions for developing such modules.…”

In this study, a tool has been designed and developed for learning about the concept of lag order within a dynamic model, which can be used in any teaching classes on statistics and financial data computation. To show a solution for a complex and multi-step process of finding the optimal lag order for multiple variables data series based on an information criterion a module using Visual Basic for Applications (VBA) for Microsoft Excel (MS Excel) is being developed. This module can be used for estimating a multivariate dynamic model as well as determining the optimal lag order of such a model.
