Impact of the satellite data assimilation on the naval undersea capability is investigated using the ocean hydrographic data without and with satellite data assimilation. The former is the Navy’s Global Digital Environmental Model (GDEM) providing the monthly mean; and the latter is the Modular Ocean Data Assimilation System (MODAS) proving the synoptic data. The two environmental datasets are ...

in this paper the response modification factor due to ductility and saved strength of cylindrical concrete elevated and ground tanks is obtained using finite element method and nonlinear push over analysis considering the lateral effective modes of tanks. to modeling the behavior of the tank materials, the five parameters william-warnke and prefect elastoplastic models are used for concrete and...

elevated water tanks as one of the main lifeline elements are the structures of high importance. since they are extremely vulnerable under lateral forces, their serviceability performance during and after strong earthquakes is a matter of concern. as such, in recent years, the seismic behavior of water tanks has been the focus of a significant amount of studies. in the present work, three reinf...

Abstract Septic tank with sedimentation and anaerobic processes in the same is commonly used as a domestic wastewater treatment technology individual households communal systems. Although simple to construct, such system has some problems, effluent not meeting quality requirement blocking by trash suspended solid before second chamber. This research aims develop new septic design that simpler c...
