this paper is about experimental results for partial reduction of vortex at vertical pipe intakes. one of the easiest and practical ways of reducing vortex effect is to use anti-vortex plates or baffles. these plates can be used to avoid the vortex completely or partially. this paper will concentrate on the latter case. rectangular plates with different dimensions have been placed at different ...

Abstract Most previous studies have focused on adjustable complex flap gates and little research has been carried out simple inline top-hinged plates for flow measurement. The present study investigates discharge measurement by located along channels under free condition. proposed device is a portable one. Two models are based Buckingham's theorem of dimensional analysis. first model (Model I) ...

Rapid advancement of technology in artificial intelligence and computer science knowledge and then feel the need to search and secure automated systems are because of the appearance of intelligent systems based on image processing and spread this knowledge. One of these intelligent systems is license plate recognition (LPR) system. LPR plays an important role in intelligent transportation syste...
