Electromagnetic acoustic transducers (EMATs) can generate non-dispersive T(0,1) mode guided waves in a metallic pipe for nondestructive testing (NDT) by using a periodic permanent magnet (PPM) EMAT circular array. In order to enhance the excitation efficiency of the sensor, the effects of varying the number of elements of the array on the excitation(More)
It has been demonstrated that breviscapine is able to treat coronary disease and reduce the inflammatory response; however, there are no relevant reports concerning its effects on the expression of inflammatory factors in acute lung injury induced by left heart ischemic reperfusion and the underlying mechanisms. In this study, we created a left heart(More)
The non-contact magnetostrictive sensor (MsS) has been widely used in the guided wave testing of pipes, cables, and so on. However, it has a disadvantage of low excitation efficiency. A new method for enhancing the excitation efficiency of the non-contact MsS for pipe inspection using guided waves, by adjusting the axial length of the excitation magnetic(More)
In this paper, according to the technical characteristics of the maintenance of cable of cable-stayed bridges, a new robot for cable maintenance is developed. The climbing equipment, the surface inspection equipment and the internal defects inspection equipment, the cleaning equipment, the spraying equipment for cable maintenance are all designed as(More)
Condition assessment of cables has gained considerable attention for the bridge safety. A magnetic flux leakage and magnetostrictive guided wave hybrid transducer is provided to inspect bridge cables. The similarities and differences between the two methods are investigated. The hybrid transducer for bridge cables consists of an aluminum framework, climbing(More)
Tumor suppressor in lung cancer 1 (TSLC1) is tightly implicated in a variety of biological processes and plays critical roles in tumor development and progression. However, the roles of TSLC1 in cutaneous squamous cell carcinoma (CSCC) remain to be unraveled. Here, we reported the TSLC1 gene that was significantly downregulated in CSCC tissues and cells,(More)
The magnetostrictive guided wave sensor with a single induced winding cannot distinguish axially symmetric from non-axially symmetric features in a pipe, because it is impossible for the sensor to detect the non-axially symmetric mode waves. When we study the effect of the change of the magnetic field in the air zone for receiving the longitudinal guided(More)
Cloud computing is a rising IT industry. How to charge for cloud computing is an important problem to be solved urgently at present. By analyzing and sorting, this article designs a charging model based on infrastructure layer in cloud computing called the infrastructure cloud. This article also proposes a Petri net which introduces costs and profits. A(More)
There are over 200 cable-stayed bridges in China. Damage detection for stay cables is an urgent problem. The broken wire detection is investigated based on the magnetostrictive guided wave technology by experimentally. Two custom-built stay cables with several broken wire flaws are detected by a magnetostrictive guided wave testing system. The results(More)
