Cavitation is among the most complicated and common damages of spillway structures. This phenomenon is controlled by different parameters including the pressure, flow velocity, spillway surface material, operation time, and air flow content. The cavitation index is calculated along the spillway and compared with its critical value using the measured values of the flow’s hydraulic parameters. Th...

understanding people’s ecological behaviors and the impacts of human activities on natural environment is one of the most important concepts in ecological psychology research. the purpose of this study was to investigate causal relationship between factors and maize growers’ ecological behavior concerning the application of external inputs such as water, fertilizers, chemical pesticides, and ma...

With the growing popularity of Internet applications and the widespread use of mobile Internet, Internet traffic has maintained rapid growth over the past two decades. Internet Traffic Archival Systems (ITAS) for packets or flow records have become more and more widely used in network monitoring, network troubleshooting, and user behavior and experience analysis. In this paper, we survey bitmap...

n this work, computational fluid dynamics of the flow behavior in a cold flow of fluidized bed is studied. An improved finite volume based finite element method has been introduced to solve the two-phase gas/solid flow hydrodynamic equations. This method uses a collocated grid, where all variables are located at the nodal points. The fluid dynamic model for gas/solid two-phase flow is based on ...

Road surfaces are affected by rain, snow, and ice, which influence traffic flow. In this paper, a microscopic flow model based on weather conditions is proposed. This characterizes the severity index. The Intelligent Driver (ID) behavior constant acceleration exponent resulting in similar regardless of conditions, unrealistic. ID proposed models evaluated over circular road length 800 m. result...
