Excellent work at a fair price

I like working with computers and specially programming in c#. At my job i'm doing web applications using c# and other Microsoft technologies. I 'm an employee over five years now and i love it . My areas of expertise are: -C#(Web and Desktop) ,Sql, Microsoft Office. I also have a PhD in chemical engineering, my main research including the use of artificial intelligence techniques (especially artificial neural networks, evolutionary algorithms and artificial immune systems) for modeling and optimization of complex chemical engineering processes.

Modeling of oxygen mass transfer in the presence of oxygen-vectors using neural networks developed by differential evolution algorithm

Engineering Applications of Artificial Intelligence
The search capabilities of the Differential Evolution (DE) algorithm - a global optimization technique - make it suitable for finding both the architecture and the best internal parameters of a neural network, usually determined by the training phase. In this paper, two variants of the DE algorithm (classical DE and self-adaptive mechanism) were used to obtain the best neural networks in two distinct cases: for prediction and classification problems. Oxygen mass transfer in stirred bioreactors is modeled wi

Optimization methodology based on neural networks and self-adaptive differential evolution algorithm applied to an aerobic fermentation process

Applied Soft Computing
The determination of the optimal neural network topology is an important aspect when using neural models. Due to the lack of consistent rules, this is a difficult problem, which is solved in this paper using an evolutionary algorithm namely Differential Evolution. An improved, simple, and flexible self-adaptive variant of Differential Evolution algorithm is proposed and tested. The algorithm included two initialization strategies (normal distribution and normal distribution combined with the opposition base

Freeze-drying modeling and monitoring using a new neuro-evolutive technique

Chemical Engineering Science
This paper is focused on the design of a black-box model for the process of freeze-drying of pharmaceuticals. A new methodology based on a self-adaptive differential evolution scheme is combined with a back-propagation algorithm, as local search method, for the simultaneous structural and parametric optimization of the model represented by a neural network. Using the model of the freeze-drying process, both the temperature and the residual ice content in the product vs. time can be determined off-line, g
