Variations of the testicular artery have been commonly described by many authors, although reports for accessory or double testicular arteries were scarce. The testicular vein displays a great variability as regards their numbers, courses, and sites of termination. We present here a single right testicular vein dividing into three trunks at the terminal drainage, and the bifurcated right testicular...
For the steel cord conveyor belt many types of defect signal classification is studied and the classification method based on the support vector machine optimized by particle swarm algorithm considering shrinkage factor(PSO-SF-SVM) is proposed. The PSO-SF-SVM method was carried out to achieve the defect classification for steel cord conveyor belt. The result shows the PSO-SF-SVM method has high classification...
Electromagnetic signal of steel cord conveyor belt defect is easy to be disturbed by Strong non-stationary noise in coal mine, even some defect signal may be overwhelmed by noise. Therefore, the defect signal noise reduction method based on a combination of wavelet packet and RLS adaptive filtering was put forward. Firstly, defect signal was decomposed by wavelet packet and got multi layer high frequency...
Renal artery variations including their source, number, and course are very common. Accessory renal arteries were discovered frequently on the left side; these arteries entered the upper or lower poles of the kidney. The present cadaver showed a testicular artery origin of the accessory renal artery, which was seldomly described previously.
