abstract stochastic model for synthetic data generation is not available for daily flows of intermittent streams. such a model is required in the planning and operation of structures on an intermittent stream for purposes where short time flow fluctuations are important. in this study a model is developed for such a case. the model consists of four steps: determination of the days on which flow...

An increase in the flow velocity in flowthrough large porous media and deflection of flow regime from Darcy law causes a nonlinear relationship between hydraulic gradient and pore velocity of media. So many investigations have done previously in such Medias. One of the most important subjects in flowthrough large porous media is relationship between friction coefficient and flow characteristics...

in this paper, static performance characteristics for a finite lenght two-lobe journal bearing lubricated with micropolar fluid is studied. using finite element method, steady-state film pressure is obtained by solving modified reynolds equation, based on micropolar lubrication theory. with the help of film pressure in bearing, the static performance characteristics in terms of load carrying ca...

In the Internet, statistical perspective of global traffic flows has been considered as an important key to network management. Nonetheless, it is expensive or sometime difficult to measure statistics of each flow separately. Therefore it is of practical importance to infer unobservable statistical characteristics of flows from characteristics of the aggregated-flows which are easily measured a...

to enhance the understanding of the impact of obstacle buildings on pollution transportationand dispersion in the atmospheric boundary layer, it is necessary to know the atmospheric flow characteristics over terrains. wind flow characteristics in a boundary layer over a step-shaped cliff topography model with rough and smooth surfaces were studied numerically using computational fluid dynamics ...

according to the former researcher’s presented relations for flow through rock-fill porous media, the effects of physical characteristics was not studied separately. hence, due to the application of these relations, physical characteristics of porous materials effect must be investigated separately. in various constructed physical models of porous media, the effect of several variables such as ...
