Quantum high-frequency conductivity oscillations in graphene multilayers and nodal semimetals in a tilted magnetic field
(Springer, 2017)
A new type of angular oscillations of the high-frequency conductivity for conductors with a band-contact line has been predicted. The effect is caused by groups of charge carriers near the self-intersection points of the ...

Intersection numbers of geodesic arcs
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Matemáticas - Sociedad Colombiana de Matemáticas, 2015-07-01)
For a compact surface S with constant curvature -κ (for some and kappa 0) and genus g ≥ 2, we show that the tails of the distribution of the normalized intersection numbers i(α, β)/l(α)l(β) (where i(α, β) is the intersection ...

Enumeration of Surfaces Containing an Elliptic Quartic Curve
(American Mathematical Society, 2014-10)
A very general surface of degree at least four in P 3 contains no curves other than intersections with surfaces. We find a formula for the degree of the locus of surfaces in P 3 of degree at least five which contain some ...
Extração de feições retas com precisão subpixel: estudo comparativo entre três métodos
(Universidade Federal do Paraná (UFPR), Centro Politecnico, 2008-01-01)
In the fields of Machine Vision and Photogrammetry, extracted straight lines from digital images can be used either as vector elements of a digital representation or as control entities that allow the determination of the ...

Region tracking on surfaces deforming via level-sets methods
(IEEE, 1999)
Since the work by Osher and Sethian (1988) on level-sets algorithms for numerical shape evolutions, this technique has been used for a large number of applications in numerous fields. In medical imaging, this numerical ...
