mirizzi’s syndrome is a rare complication of gallstone disease , that gallbladder lumen can lie alongside the common hepatic duct, resulting in inflamation and resultan bile duct stricture . most cases are not indentified preoperatively. variations of the cystic duct and its point of :union: with the common hepatic duct are surgically important . here, we present an unusual case of type i miriz...

The present work is concerned with the experimental analysis of thermal and hydraulic performance Al2O3−H2O nanofluid flow in dimpled rib arc pattern a square duct. Alumina consists nanoparticles having size 30 nm. Reynolds number Renum studied duct range from 5000 to 26,000. nanoparticle volume fraction (ϕnp) ranges 1.5% 4.5%, ratio dimpled-arc-rib-height print-diameter HAD/Pd 0.533 1.133, dim...

This paper deals with the implementation of an active noise control system in a duct using the error coded least mean square (ECLMS) algorithm. The effects caused by the secondary path were reduced using a filter-x structure. The system was implemented in the digital signal processor TMS320C6713 from Texas Instruments. The experimental results show that using the ECLMS algorithm the low frequen...
