An alternative approach for numerical calculation of the square-wave voltammograms using the mathematical programming package MATHCAD is presented. A quasi-reversible redox reaction is considered and a mathematical model is developed under conditions of the square-wave voltammetry (SWV). Application of the mathematical model in MATHCAD is discussed and the file used for numerical simulation is ...

The liquid cargo replenishment decision based on ship’s stability, strength and the floating state is a multiobjective optimization problem. The mathematical model of multi-objective is built in this paper. Aiming to obtain the feasible solution, the adaptive step ergodic of permutation and combination is applied in terms of the cargo oil tank and the water ballast tank. particle swarm optimiza...

A central question in cognitive neuroscience concerns the extent to which language enables other higher cognitive functions. In the case of mathematics, the resources of the language faculty, both lexical and syntactic, have been claimed to be important for exact calculation, and some functional brain imaging studies have shown that calculation is associated with activation of a network of left...

During setting up a mathematical model, it can be very important and difficult task to choose input parameters that should be known for solution of this problem. A similar problem might come up when someone wants to carry out an engineering calculation task. A very essential aim technical education is developing of good logical engineering thinking. One main part of this thinking is to determin...

In this research, the activity of MnO, produced during steel making in aluminate-rich slags, was investigated. According to thermodynamic equations and mathematical calculation, a series of relations was obtained for evaluation of oxide activity using Masson’s theory. The obtained relations were solved according to Levenberg- Marquardt method and using Matlab software. The results were correlat...

BACKGROUND Accurate calculation of dosages and safe administration of medications in clinical practice is an essential skill for the registered nurse. Appropriate educational preparation of student nurses is the key to ensuring they become safe practitioners in the workforce. A review of the literature on different approaches for teaching and assessing medication calculation with student nurses...

calculating total cast of bank resources procurement methods which include current -free loan deposit, saving interest-free loan deposit, regular and net short-term investment deposit, long-term investment deposit and surety bond cash deposit and presenting their optimal integration require precise scientific studies. hence, this study is an attempt to know which methods are the best optimal in...

Background: In this study, a method for linear attenuation coefficient calculation was introduced.Methods: Linear attenuation coefficient was calculated with a new method that base on the physics of interaction of photon with matter, mathematical calculation and x-ray spectrum consideration. The calculation was done for Cerrobend as a common radiotherapy modifier and Mercury.Results: The values...

Accumulation of sediment transport volume and reduce the useful life of dams, water storage tanks can be. So far, many methods for calculating sediment this is presented in reservoirs are generally classified into two categories: mathematical modeling and experimental .This study examines the effect of using Gstars model parameters in the model, deposition of sediment in the reservoir tank and ...
