High Mass Ratio Contact Binaries: Recent Evolution into Contact? [PDF]
International Astronomical Union Colloquium, 1989 Recent theories of the origin and evolution of contact binaries suggest that the two stars evolve into contact through angular momentum loss (AML; Mochnacki 1981, Vilhu 1982). When in contact, the system then evolves toward smaller mass ratio through mass transfer from the secondary to the primary component (Webbink 1976, Rahunen and Vilhu 1982).

Effects of ITO Contact Sizes on Performance of Blue Light MicroLEDs
Nanoscale Research Letters, 2022 In this study, the effect of ITO contact ratio for blue light micro-light-emitting diode (µLED) with dimensions 40 μm × 40 μm was assessed. The contact ratio from 0.2 to 0.8 was designed for the ratio of electrode area to light-emitting area.

Design of high-reduction hypoid gears meshing in plane of action
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2017 This paper proposes a method of directly designing the surface of action of a hypoid gear. In the proposed method, the characteristics of the gear meshing are independent of the manufacturing process.
