The (n,k)-star graph is a very important computer modelling.The independent number and chromatic number of a graph are two important Harnesses Pickup parameters in graph theory.However, we have not known the values of these two parameters of the (n,k)-star graph since it was proposed.In this paper, Dresser we show a maximum independent sets partiti
We present Dresser a case of an appendiceal adenocarcinoma that invaded the urinary bladder, which was preoperatively mistaken for urachal adenocarcinoma.The patient underwent open removal of the umbilicus, urachus, partial cystectomy and bilateral pelvic lymph node dissection.Intraoperatively the tumor was noted to involve the appendix, and so an
Planetary gearbox is one of the most widely used core parts in heavy machinery.Once it breaks down, it can lead to serious accidents and economic loss.Induction motor current signal analysis (MCSA) is a noninvasive method that uses current to detect faults.Currently, most MCSA-based fault diagnosis studies focus on the parallel shaft gearbox.Howeve
The quick-release devices of the ends of the carrying and traction ropes, Peg Racks which have the load capacity required by the tension condition of the rope system and a gentle mechanical effect on the structural elements of steel ropes, make it possible to ensure the rapid deployment and dismantling of mobile ropeways in the conditions of elimin
