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 ...

Conic Optimal Energy Flow of Integrated Electricity and Natural Gas Systems
Journal of Modern Power Systems and Clean Energy, 2021 In this letter, we propose a market-based bi-level conic optimal energy flow (OEF) model of integrated electricity and natural gas systems (IENGSs). Conic alternating current optimal power flow (ACOPF) is formulated in the upper-level model, and the ...

A gradient-type deformation of conics and a class of Finslerian flows
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2017 The aim of this paper is to produce new examples of Riemannian and Finsler structures having as model a scalar deformation of conics inspired by the scaling transformation.

Graphic representation of a triaxial ellipsoid by means of a sphere in general collinear spaces [PDF]
Facta Universitatis. Series: Architecture and Civil Engineering, 2011 For graphic representation of the projective creations, such as the quadrics (II degree surfaces) in projective, general collinear spaces, it is necessary to firstly determine the characteristic parameters, such as: vanishing planes, axes and centers ...

Discrete Dynamics in Nature and Society, 2021 Conic finance is a new and exciting development in quantitative finance, which is widely applied to several topics in finance. The theory of conic finance extends the law of one price to the law of two prices, which yields closed forms for bid-ask prices

On the number of ordinary conics
, 2016 We prove a lower bound on the number of ordinary conics determined by a finite point set in $\mathbb{R}^2$. An ordinary conic for a subset $S$ of $\mathbb{R}^2$ is a conic that is determined by five points of $S$, and contains no other points of $S ...

A novel camera calibration method for fish-eye lenses using line features [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014 In this paper, a novel method for the fish-eye lens calibration is presented. The method required only a 2D calibration plane containing straight lines i.e., checker board pattern without a priori knowing the poses of camera with respect to the ...
