Understanding flow in the three-dimensional phase space is challenging both to human experts and current computer science technology. To break through the barrier, we are building a program called PSX3 that can autonomously explore the flow in a three-dimensional phase space, by integrating AI and numerical techniques. In this paper, I point out that quasi-symbolic representation called flow ma...

urinary 1-hydroxypyrene is frequently used as a major metabolite and biological indicator of the overall exposure to polycyclic aromatic hydrocarbons. in this study, solid phase extraction was appropriately conditioned with regard to sample ph, sample concentration, loading flow rate, elution solvent, washing solvent, sample volume and sorbent mass. octadecyl silica cartridge (c18) was used as ...

heat transfer phenomena in batch fluidized bed dryer have been studied and analyzed using three phase model including solid phase, interstitial gas phase and bubble phase based on rizzi model. new correlations of heat transfer coefficient to surrounding and convection heat transfer coefficient between solid and interstitial gas are being proposed. in addition, some modifications have been done ...

in our search for new anticancer medicinal plants, the antiproliferative activity of the methanol extract of daphne mucronata (thymelaeaceae) was evaluated using human myelogenous leukemia k562 cells. the cells responded to plant treatments in a dose dependent manner and the ic50 of the crude extract (equivalent to 1 g of plant leaves powder per ml) and the purified active component were found ...

Two mismatch functions (power or current) and three coordinates (polar, Cartesian and complex form) result in six versions of the Newton–Raphson method for the solution of power flow problems. In this paper, five new versions of the Newton power flow method developed for single-phase problems in our previous paper are extended to three-phase power flow problems. Mathematical models of the load,...

in order to present a new and high performance structure of pem fuel cell and study the influence of the flow direction and distribution on the rate of reactants diffusion, three novel models of vertical reactant flow injection into the anode and cathode reaction area field have been introduced. they consist of one inlet and two inlets and also a continuous channel. the governing equations on t...

in this study, performance of oil droplet separator in crankcase ventilation system for three engines, ford-ecoboost (impactor with variable area), nissan-vq37de (inertial impactor), and peugeot-xu7 (cyclone) at the same volumetric flow rate has been studied experimentally. because of the complexities of geometrical and functional in internal combustion engines, a test rig is designed to study ...

We describe an operator splitting technique based on physics rather than on dimension for the numerical solution of a nonlinear system of partial differential equations which models three-phase flow through heterogeneous porous media. The model for three-phase flow considered in this work takes into account capillary forces, general relations for the relative permeability functions and variable...
