Infilling streamflow data using feed-forward back-propagation (BP) artificial neural networks: Application of standard BP and pseudo Mac Laurin power series BP techniques

Infilling streamflow data using feed-forward back-propagation (BP) artificial neural networks: Application of standard BP and pseudo Mac Laurin power series BP techniques

Hydrological data (e.g. rainfall, river flow data) are used in water resource planning and management. Sometimes hydrological time series have gaps or are incomplete, or are not of good quality or are not of sufficient length. This problem seems to be more prevalent in developing countries than in developed countries. In this paper, feed-forward artificial neural networks (ANNs) techniques are ...

In recent years, many efforts have been made to reduce pollution in compression ignition engines. Dimethyl ether is one of the methods to achieve this goal due to its special properties such as high Cetane number and low pollution. Also, one of the parameters that plays an important role in improving combustion and engine performance is fuel injection pressure. In the present study, a numerical...

Prediction of rotary machinery degradation status based on vibration data using back propagation (BP) neural network

Rotary machinery has to be maintained and repaired exactly once or several times before they totally failed to keep their good working status. In order to determine the maintenance interval of rotary machinery, machine condition should be predicted by some diagnostic methods and predictive methods. This study was conducted to establish the relationship between machine performance and machine vi...

Performance Comparison of Feed Forward Neural Network Using Various Bp Algorithms

Multiplicative Operations in Bp*bp

where S is the Landweber-Novikov algebra. S has the added advantage of being a cocommutative Hopf algebra over Z. This paper does not remove this difficulty, but we will show that the monoid of multiplicative operations in BP*BP, (i.e. those operations which induce ring endomorphisms on BP*X for any space X)9 which we will denote by Γ{BP), has a submonoid analogous to the monoid of multiplicati...
