We present a numerical study of emulsions in homogeneous and isotropic turbulence at $Re_\lambda=137$. The problem is addressed via Direct Numerical Simulations (DNS), where the Volume Fluid (VOF) used to represent complex features liquid-liquid interface. consider mixture two iso-density fluids, fluid properties are varied with goal understanding their role modulation, particular volume fracti...

One of the most important Fuel cells (FCs) is Proton Exchange Membrane Fuel Cells (PEMFCs). The outputvoltage of this FC depends on current loads. This paper tries to introduce, implement and control the voltage ofPEMFC, during load variations. The output voltage of fuel cell should be constant during load variation. Toachieve this goal, a controller should be designed. Here, the Lead-Lag contr...

In this article, we propose an extension of the multi-Weber facility location problem with rectilinear-distance in presence passages over a non-horizontal line barrier. For single-facility case, develop exact heuristic based on divide-and-conquer approach that outperforms alternative heuristics available literature. The multiple facilities case is solved by means application alternate-location-...

BACKGROUND Klippel-Trenaunay-Weber syndrome is a rare syndrome; unfortunately, very few studies of the connection between hypersplenism, nephrotic syndrome, and Klippel-Trenaunay-Weber syndrome have been published. CASE PRESENTATION We report the case of a 40-year-old white man with a typical clinical presentation of Klippel-Trenaunay-Weber syndrome, including "port-wine stains," varicose vei...

recently, the economic crisis has resulted in instability in stock exchange market and this has caused high volatilities in stock value of exchanged firms. under these conditions, considering uncertainty for a favorite investment is more serious than before. multi-objective portfolio selection (return, liquidity, risk and initial cost of investment objectives) using minmax fuzzy goal programmin...
