an artificial neural network has been used to determine the volume flux and rejections of ca2+ , na+ and cl¯, as a function of transmembrane pressure and concentrations of ca2+, polyethyleneimine, and polyacrylic acid in water softening by nanofiltration process in presence of polyelectrolytes. the feed-forward multi-layer perceptron artificial neural network including an eight-neuron hidden la...

in this study, artificial neural network was used to predict the surface tension of 20 hydrocarbon mixtures. experimental data was divided into two parts (70% for training and 30% for testing). optimal configuration of the network was obtained with minimization of prediction error on testing data. the accuracy of our proposed model was compared with four well-known empirical equations. the arti...

pneumatic rectosigmoid rapture is usually occurred following the inappropriate fun by direct entering a high volume of the air through the pneumatic device to the anus. such an event was reported for the first time in 1904 by stone. diagnosis and treatment of such injuries are often delayed because of some social limitations and preventing the patient form explaining the event. colon sigmoid ru...

We propose a novel approach to self-regenerating continuously-operating systems. Such systems provide best-case solutions in security surveillance or decision making centers. We introduce HADES, a self-regenerating system whose agents acknowledge their “citizenship” or faithfulness to the good of the system and are able to monitor their environment. When agents of HADES find irregularity in the...

In this article, I present the state of my research on modeling and simulating the impact of a culture on artificial organizations and artificial societies. In particular, I aim at replicating the effect of culture at the individual level in order to observe the consequences at the collective level. Thus, I expect to reproduce organizational structural and performance (efficiency, robustness, f...

Embryonics (embryonic electronics) is a research project which attempts to draw inspiration form the world of biology to design better digital computing machines, and notably massively parallel arrays of processors. In the course of the development of our project, we have realized that the use of programmable logic circuits (field-programmable gate arrays, or FPGAs) is, if not indispensable, at...

Embryonics is a long-term research project attempting to draw inspiration from the biological process of ontogeny, to implement novel digital computing machines endowed with better fault-tolerant capabilities. For this purpose FPGAs are extremely useful. However, through this project we designed MuxTree, a new coarse-grained FPGA, to implement our embryonic machines. This article focuses on the...
