Let Mn be an n-dimensional complete connected and oriented hypersurface in a hyperbolic space Hn+1 (c) with constant k-th mean curvature Hk > 0(k < n) and with two distinct principal curvatures, one ...

We prove a relation between the k-dimensional totally geodesic Radon transforms on the various constant curvature spaces using the geodesic correspondence between the spaces. Then we use this relation ...

Fulcrum Acoustic, the Whitinsville, Mass.-based, loudspeaker and audio equipment manufacturer, launched the CC Series, a constant curvature subcardioid array system. The new Series is designed for ...

Nucleation and growth is the dominant relaxation mechanism driving first-order phase transitions. In two-dimensional flat systems, nucleation has been applied to a wide range of problems in physics, ...

Efficient drilling in shale reservoirs requires detailed 3-dimensional (3D) horizontal well trajectories. An orthogonal-arc trajectory (OAT) method assumes a single constant curvature in the curved ...

Changes in directional drilling and surveying practices could lead to a reduction in positional errors arising from nonconstant wellbore curvature. Part 1 of this series (OGJ, Oct. 27, 2003, p. 51) ...
