The self-calibration approach based on the absolute conic or its dual, the absolute dual quadric, has the merit of allowing the intrinsic camera parameters to vary in image sequence. In this paper, we show that certain linear equations resulting from the in2nity homography can be added to a system of originally undetermined linear equations to 2nd the absolute dual quadric for a stereo head. Th...

A bstract Celestial and momentum space amplitudes for massless particles are related to each other by a change of basis provided the Mellin transform. Therefore properties celestial have counterparts in vice versa. In this paper, we study avatar dual superconformal symmetry $$ \mathcal{N} N = 4 Yang-Mills the...

Computational methods are proposed for solving a convex quadratic program (QP). Active-set methods are defined for a particular primal and dual formulation of a QP with general equality constraints and simple lower bounds on the variables. In the first part of the paper, two methods are proposed, one primal and one dual. These methods generate a sequence of iterates that are feasible with respe...

Two coupled delay-line oscillators are modeled by a system of delay differential equations, and their oscillations are analyzed by reducing the delay equations to a system of ordinary differential equations on a finite-dimensional center manifold in the corresponding infinitedimensional state-space. After averaging the finite-dimensional system, a bifurcation analysis reveals a complex structur...

A numerical study has been conducted to investigate the modelling of steady two-dimensional stagnation-point flow and diffusion of chemically reactive species of a viscous and incompressible fluid past a permeable quadratically stretching/ shrinking sheet. Similarity transformation has been used to reduce the governing nonlinear partial differential equations into a system of nonlinear ordinary...

We consider the brane universe in the bulk background of the charged topological AdS black holes. The evolution of the brane universe is described by the Friedmann equations for a flat or an open FRW-universe containing radiation and stiff matter. We find that the temperature and entropy of the dual CFT are simply expressed in terms of the Hubble parameter and its time derivative, and the Fried...
