Abstract In this research, a radial basis function artificial neural network (RBF-ANN) model was developed to predict the hot deformation flow curves of API X65 pipeline steel. The results of the developed model was compared with the results of a new phenomenological model that has recently been developed based on a power function of Zener-Hollomon parameter and a third order polynomial functio...

Fig, 1,-25-year-old man with parapharyngeal angiofibroma. A, Unenhanced axial CT scan shows a mass (arrows) in parapharyngeal space, with anterior displacement and splaying of pterygoid plates. B, Enhanced coronal CT scan shows an enhancing left-sided parapharyngeal mass (arrows) displacing pharynx toward right. C, Angiogram of left common carotid artery shows a hypervascular mass (arrows) supp...

The NIST robot vehicle, a HMMWV with sensors and computer controlled actuators, detects and avoids obstacles while it drives off road at speeds up to 35 km/h. During tests the vehicle drives through the back fields of NIST detecting large obstacles up to 50 m away. Obstacles are sensed using a 30¡x60¡ field of view laser range scanner. The planner computes smooth, obstacle free paths that follo...

Abstract. The mechanical and damage behavior of a X100 steel after prestrain is studied in this work. Experimental results show both a plastic and rupture anisotropy: the T direction exhibits a higher ultimate stress but the lowest ductility and toughness. Prestrain reduces ductility and crack growth resistance. A model able to represent the plastic and damage behaviour of the material before a...

Valves are usually used in conjunction with large water-tower storage structures. Large pipes carry water from the storage tower to the flush gutter. Valves are used at appropriate locations in the pipeline to control flush water flow to individual gutters. Figure 1 is a schematic layout of a flush system using storage towers, pipelines and valves to flush several gutters. Use of multiple, inte...
