We then extend the source time reversal method, originally developed for acoustic waves, to an elastic system of waves. Additionally, we present a fast reconstruction implementation for large data sets. This is especially useful in the elastic case, in which the numerical cost is higher than in...
Time-reversed equations There are a number of systems that can detect partial discharges, but they aren't very effective in pinpointing where they originate. "With our method, engineers can locate the source of a partial discharge and act quickly to solve the problem," says Hamid Reza Karami,...
The invention provides an ultrasonic scanning and detection method based on a sonic time reversal method, comprising the following steps: arranging an imaginary sound source at a preset focal point to transmit sound pulses, calculating acoustical signals received by each array element of an energy ...
We perform theoretical analysis of the method of field focusing in a randomly inhomogeneous waveguide using reradiation of the received signal with time reversal. The simplest case where point sources and receivers are used for emission and reception is considered. As an example, the waveguide is ...

The Time Reversal (TR) method for scatterer identification is considered. • An improved TR method is proposed for cases of scarce or very noisy data. • The improvement is achieved by solving an elliptic problem at chosen times. • ...
Using backstepping technique and adaptive sliding mode control method, a global asymptotically tracking control law is developed. 针对动力学模型描述的非完整移动机器人系统,研究了其在未知参数和不确定性干扰下的轨迹跟踪控制问题,基于反演技术和自适应滑模控制的思想设计了具有全局渐近稳定的轨迹跟踪控制律。 2....
