Abstract Plain bearings are increasingly being used under mixed friction, resulting in a higher risk of wear-induced failure. Therefore, the relevance condition monitoring is increasing, which can enable early detection wear inducing conditions. The presented work focuses on development an energy-autonomous, temperature-based system for plain . components to be integrated directly into machine ...

Supersonic biplanes can achieve low-boom and low-drag supersonic flights. In the present study, aerodynamic analysis of a two-dimensional stagger Bussmann biplane (staggered upper element by 0.5c) at zero degrees angle attack with trailing edge flap was investigated help computational fluid dynamics (CFD) tools. Due to wave cancellation effect, Busemann delivers positive drag reduction design M...

We propose an algorithm based on Newton’s method and subdivision for finding all zeros of a polynomial system in a bounded region of the plane. This algorithm can be used to find the intersections between a line and a surface, which has applications in graphics and computer-aided geometric design. The algorithm can operate on polynomials represented in any basis that satisfies a few conditions....
