Ultrasonic techniques can be used non-invasively on chemical and process plant because it is often possible to penetrate the walls of the plant with ultrasound.Ultrasonic transmitters and receivers typically make use of the piezo electric SR effect.Application at high temperatures and in hazardous environments is possible.Ultrasonic techniques are
The global ecosystem relies on the metabolism of photosynthetic organisms, featuring the ability to harness light as an energy source.The most successful type of photosynthesis utilizes a virtually inexhaustible electron pool from water, but the driver of this oxidation, sunlight, varies on time and intensity scales of several orders of magnitude.S
A novel bearing performance degradation assessment method based on convolutional sparse coding and combination learning is proposed in this paper, which can avoid the impact of the traditional features on the assessment results under complex operation conditions.The vibration signal can be decomposed into the convolution of the kernel sets and thei
