A case of cylindrical cell papilloma (CCP) arising in the maxillary sinus is described. Light and electron microscopic findings revealed the characteristic oncocytic nature of the neoplasm. A review of the literature confirms the rarity of CCP and its behavioral similarities to the more common inverted papilloma. The relatively high rate of recurrence,

Straightness, flatness and cylindricity characterization using discrete Legendre polynomials
, 2020In dimensional metrology the straightness, flatness or cylindricity of surfaces is commonly measured at a limited number of equidistant points on the surface. This paper describes some opportunities and characteristics of discrete Legendre polynomials to

Assessing cylindricity for oblique cylindrical features
International Journal of Machine Tools and Manufacture, 2000This research investigates the algorithmic aspect of cylindricity assessment. With the surface points measured with coordinate measuring machines (CMMs), cylindricity can be assessed under different kinds of reference cylinders. In order to explore the full capability of CMMs, supplementary methodologies for finding a fine-tuned axis of the cylinder ...

The Fourier series for the charge density on a hollow tube of finite length is found in such a way that the Fourier coefficients are the unknowns of a system of linear equations. A machine method is used to solve the set of equations in finite order.

General optimization models for the dimensional synthesis of defect-free Revolute-Cylindrical-Cylindrical-Cylindrical linkages with static loading are formulated and evaluated in this work. With these optimization models, Revolute-Cylindrical-Cylindrical-Cylindrical linkage dimensions required to approximate coupler positions or coupler path points ...

Cylindrical Gravitational News
Journal of Mathematical Physics, 1966The concepts of news function and mass aspect are generalized to a class of cylindrically symmetric metrics containing both degrees of freedom of the gravitational field. It is proved that the mass/unit length always decreases if there is any cylindrical news.
