in this paper, the boundary-based estimation of pressure distribution in the cardiovascular system is investigated using two dimensional flow images. the conventional methods of non-invasive estimation of pressure distribution in the cardiovascular flow domain use the differential form of governing equations. this study evaluates the advantages of using the integral form of the equations in the...

We approximate the distribution of the TCP-flow rate by deriving it from the joint bivariate distribution of the flow sizes and flow durations of a given access network. The latter distribution is represented by a bivariate extreme value distribution using the Pickand’s dependence A-function. We estimate the A-function to measure the dependencies of random pairs: TCP-flow size and duration, the...

the atmospheric pressure chemical vapor synthesis (apcvs) route is a process that can be used for the synthesis of doped-nanocrystalline powders with very small crystallite sizes having a narrow particle size distribution and high purity. in this study, apcvs technique was used to prepare boron-doped titania nanopowders. the effects of temperature, borate flow rate and water flow rate on the am...

The spatial distribution of petrophysical properties within the reservoirs is one of the most important factors in reservoir characterization. Flow units are the continuous body over a specific reservoir volume within which the geological and petrophysical properties are the same. Accordingly, an accurate prediction of flow units is a major task to achieve a reliable petrophysical description o...

Coating of dispersions or suspensions of particles in a fluid is very common in the manufacturing of functional materials. Commonly, a uniform distribution of the suspended phase is required, but, in practice, agglomerates of the suspended particles appear in the final product. It has been shown experimentally that agglomeration takes place as the dispersion flows inside the coating die, before...

Rain garden (RG) has been developed and applied to low-impact designs for the purpose of water quality enhancement. A RG consists of a surface storage basin and subsurface infiltrating layers. The storage basin is designed to be shallow, flat, and wide with an overtopping weir to pass excessive flows, while the subsurface infiltrating system is composed of two layers of filtering media. The upp...
