An intelligent weavable dyeing method for the environmentally-friendly dyeing of fabric
Alexandria Engineering Journal, 2021 Yarn-dyed textiles are complementary to digital printing textiles. They promise high production and environmentally-friendly energy efficiencies. However, the complicated structures of color-blended composite yarns cause unpredictability of colors in ...

Dragging of inertial frames in the composed Kerr-Newman-orbiting-ring system
Nuclear Physics B, 2023 The dragging of inertial frames by an orbiting object, a well known phenomenon in general relativity, implies that the horizon angular velocity ΩHBH-ring of a central black hole in a composed black-hole-orbiting-ring system is no longer related to its ...

Sliding rings and spinning holes [PDF]
Journal of High Energy Physics, 2006 We construct smooth supergravity solutions describing a BPS black ring with a BPS black hole centered at an arbitrary distance above the ring. We find that as one moves the black hole the entropy of the ring remains constant, but the angular momentum coming from the supergravity fluxes changes. Our solutions also show that in order to merge a BPS black

Measuring Spin from Relative Photon-ring Sizes [PDF]
The Astrophysical Journal, 2022 Abstract The direct detection of a bright, ring-like structure in horizon-resolving images of M87* by the Event Horizon Telescope (EHT) is a striking validation of general relativity. The angular size and shape of the ring is a degenerate measure of the location of the emission region, mass, and spin of the black hole.

Nature, 1891 BISHOP COURTENAY'S questions may perhaps be clearly answered as follows. The centrifugal force of a free spinning hoop has to be balanced by its peripheral tension; but this, having a large tangential and a small radial component, acts at disadvantage, and may have to be very big to balance even a moderate centrifugal force.
