The reduction of friction-induced noise is a crucial research area for enhancing vehicle comfort, and this paper proposes a method based on circular pit texture to achieve this goal. We conducted a long-term sliding friction test using a pin-on-disc

We apply the complex method to build new exact solutions for the conformable Huxley equation. The results show that abundant new exact solutions were constructed, which extends the results of Cevikel, Bekir and Zahran. Further, we extend the undeterm

By the Wiman–Valiron theory and the complex method, we prove that all meromorphic solutions of the fifth-order ODE unu′′′′′−cu=0belong to W, and obtain several new solutions of the sixth-order thin-film equation comparing to the opening
