This study, the modeling and hardware implementation of semiconductor circuit elements very frequently used in electronic circuits are carried out by using artificial neural networks and field programmable gate array chip. Initially the artificial neural network models obtained has been written in very high speed integrated circuit hardware description language (VHDL). Then, these configurations have been simulated and tested under ModelSim Xilinx software. Finally, the best configuration has been implemented under the Xilinx Spartan-3E FPGA (XC3S500E) chip of Xilinx. The modeling of electronic circuit elements is very important both in respect of engineering, and in respect of practical mathematics. The main aim is to shorten the simulation time and to examine the real physical system applications easily by using the model elements instead of using the ones used in real applications. The effectiveness of the implemented artificial neural network models on field programmable gate array was found successful.

In this theoretical study, the prediction of the corrosion resistance of Al-Si-Mg-based metal matrix composites reinforced with SiC particles has been studied, using an artificial neural network. Four input vectors were used in the construction of the proposed network; namely, volume fraction of SiC reinforcement, aging time of the composites, environmental conditions, and potential. Current was used as the one output in the proposed network. Test results indicate that the proposed network can be used efficiently for the prediction of the corrosion resistance of Al-Si-Mgbased metal matrix composites reinforced with SiC particles, and the methodology is suitable for engineers to study the corrosion of metal matrix composites. In addition, a few forecasts regarding the polarization response for different SiC volume fractions and aging conditions have also been generated without using any experimental data.

In this theoretical study, the prediction of the corrosion resistance and age-hardening behavior of an Al/TiC functional gradient material (FGM) has been investigated by using the artificial neural network (ANN). The input parameters have been selected as TiC volume fraction of the composite layers, aging periods of the composite, environmental conditions, and applied potential during the corrosion tests. Current and microhardness were used as the one output in the proposed network. Also, a new three-layered composite has been imaginarily designed to demonstrate the predictive capability and flexibilities of the ANN model as a case study. Artificially aging (T6) process and potentiodynamic scanning (PDS) tests were used for heat-treating and corrosion response of the FGS, respectively. The results showed that the generated PDS curves of the FGM and calculated corrosion parameters of the case study are quite near and in acceptable limits for similar composites obtained values in experimental studies. Besides, this study has been a great success in predicting peak-aging times and its corresponding hardness values more precisely.
