Unfolded Cylindrical Projection for Rib Fracture Diagnosis

2018
The recommended exam for assessing chest trauma is a computed tomography (CT) chest scan. Using multi-planar reconstructions to evaluate a CT volume to assess the ribcage is a tedious and time-consuming task. We have designed an application that provides an automatically rendered unfolded unobstructed view of the entire ribcage using an unfolded ...

A generic projection operator for partial cylindrical algebraic decomposition

Proceedings of the 2003 international symposium on Symbolic and algebraic computation, 2003
This paper provides a starting point for generic quantifier elimination by partial cylindrical algebraic decomposition pcad. On input of a first-order formula over the reals generic pcad outputs a theory and a quantifier-free formula. The theory is a set of negated equations in the free variables of the input formula.

A cylindrical MWPC and radial projection chamber for the E760 experiment

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1989
Abstract The central detector for the Fermilab experiment E760 on charmonium spectroscopy is described. A first report is given on the technological solutions, tested on the working detector, to achieve field shaping and to minimize Coulomb scattering.

Orthogonal Cylindrical Projection: Accessible Learning Objects

2018 XIII Latin American Conference on Learning Technologies (LACLO), 2018
Since it is considered that knowledge must be accessible to all and because it recognizes the importance of the teaching of Descriptive Geometry, a course was developed from Learning Objects (LO), accessible to the deaf public, in a Virtual Environment of Teaching and Learning (VETL) with the content of Orthogonal Cylindrical Projection (OCP).

Locating cylindrical objects from perspective projections

Proceedings of the IEEE 1991 National Aerospace and Electronics Conference NAECON 1991, 2002
The authors address the problem of finding the 3D position and orientation of a circular cylinder using one view and known values of its radius and height. Elliptical projections of the circular ends and straight line projections of the cylinder sides can be used to calculate the cylinder position up to 5 degrees of freedom.

Bi-cylindrical conformal map projection

Arabian Journal of Geosciences, 2018
Novel map projections can be derived by solving one of the two primary problems in mathematical cartography: direct and inverse. The combination of the equations of existing projections is a method that belongs to the direct problem category in mathematical cartography.

Visualization of Distortions in Cylindrical Projections

2014
Representation of Earth's surface in s plane is distorted in any map projection regardless of it being a sphere or ellipsoid surface. Lengths, areas and angles are distorted. Distortion magnitudes are one of the most important indicators of map projections' quality. Some projections preserve angles (conformal), some preserve areas (equal-area) and some

Transverse Cylindrical Stereographic and Conical Stereographic Projections

The American Cartographer, 1984
Two new map projections have projection points with locations dependent upon the location of the area to be mapped. The projection surfaces are an elliptical cylinder tangent to the generating globe or spheroid along a central meridian and a cone tangent along a standard parallel.

Note on the Use of Oblique Cylindrical Orthomorphic Projection

The Geographical Journal, 1935
On the map, the parallels are equidistant arcs of circles. The limiting position for each parallel is the point where the tangent from E touches the parallel. The boundary of the whole projection is therefore a circle, with centre at 45? latitude on the central meridian, and radius length of 45?.
