On Chasles' Property of the Helicoid in Tri-Twisted Real Ambient Space
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015 An elementary property of the helicoid is that at every point of the surface the following condition holds: cot θ = C · d; where d is the distance between an arbitrary point to the helicoid axis, and θ is the angle between the normal and the helicoid’s ...

Horizontal travelling heater method growth of Hg1−xCdxTe with crucible rotation [PDF]
, 1993 A horizontal travelling heater method (THM) for growing cylindrical cyrstals from a partially filled solution zone has been investigated for the first time. By applying ampoule rotation, the whole cross section of the crystal is successively brought into

Rotating Surfaces Promote the Shedding of Droplets
Research, 2023 Achieving rapid shedding of droplets from solid surfaces has received substantial attention because of its diverse applications. Previous studies have focused on minimizing contact times of liquid droplets interacting with stationary surfaces, yet little consideration has been given to that of moving surfaces.

THE SIMPLIFIED ROTATION METHOD
Journal of Industrial Design and Engineering Graphics, 2019 The simplified rotation method derives from the classic rotation method included in the chapter on descriptive geometry methods. This simplified method eliminates the rotation axis, being a particular case of level or front rotation methods. The omission

Rapid rotation of micron and submicron dielectric particles measured using optical tweezers [PDF]
, 2003 We demonstrate the use of a laser trap (‘optical tweezers’) and back-focal-plane position detector to measure rapid rotation in aqueous solution of single particles with sizes in the vicinity of 1 μm.

Performance impact of honing dynamics on surface finish of precoated cylinder bores [PDF]
, 2013 The surface modification of engine cylinder bores with improved sliding properties is often produced by the honing process. This multi-stage process is performed using abrasive stones loaded against the bore with simultaneous rotation and oscillation. To
