Modeling of occurrence frequencies of ion conics as a function of altitude and conic angle [PDF]
Annales Geophysicae, 2000 The occurrence frequencies of dayside ion conics with various conic angles are obtained as a function of altitude from Exos-D (Akebono) observations. We made a model calculation of ion conic evolution to match the observation results.

Confocal Families of Hyperbolic Conics via Quadratic Differentials
Axioms, 2023 We apply the theory of quadratic differentials, to present a classification of orthogonal pairs of foliations of the hyperbolic plane by hyperbolic conics.

Casimir energy in a conical wedge and a conical cavity [PDF]
Journal of Mathematical Physics, 2005 Casimir energies for a massless scalar field for a conical wedge and a conical cavity are calculated. The group generated by the images is employed in deriving the Green function as well as the wave functions and the energy spectrum.

The Role of Tectonic Activities on Configuration and Conical Enlargement of the South Foothills of Aladagh [PDF]
جغرافیا و توسعه, 2009 Conics are some geomorphological shapes which have been formed especially in the south foothills on the Aladagh hights by various factors. These factors caused shaping in the past and enlargement at present conditions. One of these factors in shaping and

Relationship of upflowing ion beams and conics around the dayside cusp/cleft region to the interplanetary conditions [PDF]
Annales Geophysicae, 2002 The dayside cusp/cleft region is known as a major source of upflowing ionospheric ions to the magnetosphere. Since the ions are supposed to be energized by an input of energy from the dayside magnetospheric boundary region, we examined the ...

Crossing limit cycles for piecewise linear differential centers separated by a reducible cubic curve
Electronic Journal of Qualitative Theory of Differential Equations, 2020 As for the general planar differential systems one of the main problems for the piecewise linear differential systems is to determine the existence and the maximum number of crossing limits cycles that these systems can exhibit.

On the Implicit Equation of Conics and Quadrics Offsets
Mathematics, 2021 A new determinantal representation for the implicit equation of offsets to conics and quadrics is derived. It is simple, free of extraneous components and provides a very compact expanded form, these representations being very useful when dealing with ...

Differential geometry of complex projective plane conics [PDF]
, 2023 In this paper we study properties of complex plane projective curves from a geometric point of view. We focus our attention on properties of conics. We find that Gauss curvature determines a conic up to a hermitian transformation preserving the Fubini ...
