Thickness detection of concrete pavement is a critical step in construction completion acceptance and serves as an important metric for subsequent performance evaluations. The crux thickness evaluation lies determining the interface reflection echo propagation sound time. Based on acoustic impedance difference between surface layer contact layer, can be classified into two types: large-differen...

Abstract Nuclear pipes require regular inspection to prevent critical damage and extend their safe working lifetime. Ultrasonic using phased array transducers is a Non-Destructive Testing (NDT) method used monitor the condition of pipes, providing internal integrity information multiple small transducer elements. This grants controllable ultrasonic beam that provides more detail than convention...

The growing demand for power is putting tremendous stress on existing power plants for generating electricity. The plants are being operated for longer periods of time under heavy load conditions. Reliability of key components of the power plant such as steam or gas turbines and generators is of prime importance. Many utilities are interested in extending the life of turbine-generator component...

Ultrasound image guidance is widely used in minimally invasive procedures, including fetal surgery. In this context, maintaining visibility of medical devices is a significant challenge. Needles and catheters can readily deviate from the ultrasound imaging plane as they are inserted. When the medical device tips are not visible, they can damage critical structures, with potentially profound con...
