THE DEVELOPMENT WITH MINIMUM MATERIAL FOR AN AESTHETIC ROTATION SURFACE [PDF]
Fiabilitate şi Durabilitate, 2018 In this paper we present the rotation surface obtained by the rotation by the vertical ax of a curved line formed of two equals circle arches. The rotation surface presented in the paper may present interest for the manufacturing of different objects.

Surface Reconstruction Using Rotation Systems [PDF]
ACM Transactions on GraphicsInspired by the seminal result that a graph and an associated rotation system uniquely determine the topology of a closed manifold, we propose a combinatorial method for reconstruction of surfaces from points. Our method constructs a spanning tree and a rotation system.

Surface gravity of rotating dumbbell shapes [PDF]
Astrophysics and Space Science, 2021 We investigate the problem of determining the shape of a rotating celestial object - e.g., a comet or an asteroid - under its own gravitational field. More specifically, we consider an object symmetric with respect to one axis - such as a dumbbell - that rotates around a second axis perpendicular to the symmetry axis.

Spinning up the Surface: Evidence for Planetary Engulfment or Unexpected Angular Momentum Transport?
The Astrophysical Journal, 2022 In this paper, we report the potential detection of a nonmonotonic radial rotation profile in a low-mass lower-luminosity giant star. For most low- and intermediate-mass stars, the rotation on the main sequence seems to be close to rigid.

Effect of cutting speed on milling process on surface roughness of ST-37 steel material workpiece
Invotek: Jurnal Inovasi Vokasional dan Teknologi, 2021 The importance of the surface roughness value of a workpiece must be of concern to students and machine operators because the surface roughness of the workpiece becomes a benchmark for the use of a component in the machining plane and one of the ...
