Matching Standard and Secant Parallels in Cylindrical Projections

open access: yesISPRS International Journal of Geo-Information, 2023
Map projections are usually interpreted by mapping a sphere onto an auxiliary surface, and then the surface is developed into a plane. It is taken as a fact without proof that the parallels in which the auxiliary surface intersects the sphere are mapped ...

Separation by cylindrical surfaces [PDF]

open access: yesProceedings of the American Mathematical Society, 1972
C. Caratheodory has established that two compact sets P and Q in Euclidean n-space can be strictly separated by a hyperplane if each subset of n + 1 or fewer points of Q can be strictly separated from P by a hyperplane. In this paper it is shown that if each subset of k or fewer points of Q can be strictly separated from P by a hyperplane (where k is a

The acoustics of curved and lined cylindrical ducts with mean flow

open access: yes, 2010
This thesis considers linear perturbations to the steady flow of a compressible inviscid perfect gas along a cylindrical or annular duct. Particular consideration is given to the model of the duct boundary, and to the effect of curvature of the duct ...

Periodic Surface Structuring of Copper with Spherical and Cylindrical Lenses

open access: yesNanomaterials, 2023
The use of a cylindrical lens in femtosecond laser surface structuring is receiving attention to improve the processing efficiency. Here, we investigate the structures produced on a copper target, in air, by exploiting both spherical and cylindrical ...

Settlement Prediction Based on the Relationship between the Empirical and Analytical Solutions of a Cylindrical Cavity under Undrained Conditions

open access: yesAdvances in Civil Engineering, 2023
Settlements on the ground surface often relate to excavating an underground cavity in cities. Movement on the ground surface can create a void between the wall of the cylindrical cavity and the lining.
