In this research, the application of multilayer perceptron (MLP) neural networks and support vector machine (SVM) for modeling the hydrodynamic behavior of Permeable Breakwaters with Porous Core has been investigated. For this purpose, experimental data have been used on the physical model to relate the reflection and transition coefficients of incident waves as the output parameters to the wid...
the treatment of in completely formed pulpless teeth has presented considrable problems. these teeth have wide open apexes and the walls of the root canal diverge toward the apical tissues. mechanical preparation cannot be done in the normal manner beacause of the large initial size and the taper of apical part of the canal , a mechanical stop cannot be produced at the apex of the canal and , t...
Dam settlement monitoring is a crucial project in the safety management of concrete face rockfill dams (CFRD) over their whole life cycle. With development an automatic system, large amount data was collected. To precisely predict structural health dams, combined multiple points (MMP) model and machine learning has been developed. In this paper, based on physical factors CFRD, we comprehensivel...
in this study, the mechanical behavior of vanyar dam was evaluated at the end of construction. a two-dimensional numerical analysis was conducted based on a finite element method on the largest cross-section of the dam. the data recorded by the instruments located in the largest cross-section were compared with the results of the numerical analysis at the place of instruments. the settlement, p...
Dams are one of the most important water structures built to meet vital needs people such as irrigation and energy. It is great importance examine seismic safety dams. In addition, it investigate interaction behavior dams due bodies dams, reservoir water, foundation being in constant interaction. Therefore, this study, clay core rockfill (CCR) investigated by considering dam-foundation-reservoi...
