Abstract: The present application provides a composite brake disc, the preparation method thereof and a friction stir tool. The composite brake disc comprises: an aluminum alloy base layer, and an aluminum matrix composite layer, where the aluminum alloy base layer and the aluminum matrix composite layer are bonded with each other through metallurgical bonding. A transition layer is formed at the boundary surface where the aluminum alloy base layer and the aluminum matrix composite layer are bonded with each other. A reinforced structure connecting the aluminum alloy base layer and the aluminum matrix composite layer is formed in the transition layer.

Abstract: Various methods and systems are provided for ultrasound imaging. In one embodiment, a method comprises acquiring, with an ultrasound transducer of a scanning apparatus during an ultrasound scan of a patient, an ultrasound image, detecting, with an artificial intelligence model, a region of interest within the ultrasound image including a possible tumor, acquiring, with the ultrasound transducer, an elastic image of tissue within the region of interest, and displaying, with a display device, the elastic image. In this way, shear wave elastography may be automatically targeted to a region of interest, thereby reducing the processing load for the analysis and enabling a higher elasticity imaging frame rate for three-dimensional ultrasound imaging.

Abstract: Aspects of the subject disclosure may include, for example, a device including a processing system that receives items of media content; delivers the items over a network according to a schedule determined by a content delivery scheduling system; detects a level of broadcast network capacity utilization; and periodically generates and transmits to the scheduling system a forecast of network capacity utilization. A new forecast is generated and transmitted responsive to the network capacity utilization deviating from the forecast by more than a predetermined tolerance. A resource for delivering the items of media content is dynamically assigned to the processing system by the scheduling system in accordance with a current forecast. The items of media content comprise a queue accessible to the content delivery scheduling system; the queue is maintained by the scheduling system and is uniquely assigned to the processing system. Other embodiments are disclosed.
