A geometric study of different curves for the rotor profiles of a twin-screw compressor [PDF]
E3S Web of Conferences, 2021 This paper presents the results of comparisons among some patented solutions for profiling the contours of the rotors in twin-screw compressors. Referring to a base case where all the generating curves are circumferences, patents suggesting to replace ...

A Geometric Theory Integrating Human Binocular Vision With Eye Movement
Frontiers in Neuroscience, 2020 A theory of the binocular system with asymmetric eyes (AEs) is developed in the framework of bicentric perspective projections. The AE accounts for the eyeball's global asymmetry produced by the foveal displacement from the posterior pole, the main ...

ON THE VISUALIZATION OF POSITIONAL PRECISION [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2021 Tasks such as image registration or pose estimation require the determination of transformations based on uncertain observations. Hence, the position of any geometric object transformed according to this estimate is also uncertain, at least in terms of ...

Fukaya Categories as Categorical Morse Homology [PDF]
, 2014 The Fukaya category of a Weinstein manifold is an intricate symplectic invariant of high interest in mirror symmetry and geometric representation theory. This paper informally sketches how, in analogy with Morse homology, the Fukaya category might result

ASPECTS AND GEOMETRIC INTERPRETATION IN SOLVING CONICAL SECTIONS
Journal of Industrial Design and Engineering Graphics, 2019 In mathematics, a conic is the curve that is obtained by intersecting a plane with a cone. Is well known that the shape of this curve may differ quite a bit depending on the position of the intersection plane relative to the cone axis, as it is actually ...

A Unified General Theory of Conic Sections via the Conic Radical
MathematicsIn this paper, we bring forth several new general formulae in the classic study of conics in the Analytic Geometry: the coordinates of all vertices and focal points of arbitrary parabolas, ellipses, and hyperbolas; lengths for all latera recta from any ...

Elementary Treatise on Melted-like Curves Derived from Center Ellipse and Circle
Iraqi Journal for Computer Science and Mathematics, 2023 This study deals with a special case in the geometry of 2D special plane curves. The research treaties the development of a method for locating points and drawing curves derived from moving points on two curved paths of conic sections, namely, circle ...
