Biometric person recognition for secure access to restricted data/services using PC with internet connection. To study, an application PC to be used as a biometric capturing device that captures the video and recognition can be performed during a standard web session. The main contribution of this novel proposal is, making comparison of portrait. Centroid context algorithm is used for selecting...

A great advance in physics came when it was realized that it was better to think about motion in empty space rather than starting with what happen in the “real world” with gravity pulling things downwards, friction slowing things down, etc. First, that the laws of physics should be the same at one point as at another, i.e. that they are translation invariant, and also from one day to another, i...

Despite his fame as a physician and social reformer, relatively few portraits of Thomas Hodgkin, MD (1798-1866), have been published. Two oil paintings, identified by the Hodgkin family as their forebear, have been a puzzle.' The faces are remarkably dissimilar. One portrait hangs in the Gordon Museum at Guy's Hospital Medical School, its artist heretofore unknown (plate 1). It shows Dr Hodgkin...

We prove a relative Poincaré embedding theorem for maps of pairs into a Poincaré pair. This result has applications: it is the engine of the compression theorem of the author’s paper in Algebr. Geom. Topol. 2, (2002) 311–336, it yields a Poincaré space version of Hudson’s embedding theorem, and it can be used to equip 2-connected Poincaré spaces with handle decompositions.

It is by now well known that the Poincaré group acts on the Moyal plane with a twisted coproduct. Poincaré invariant classical field theories can be formulated for this twisted coproduct. In this paper we systematically study such a twisted Poincaré action in quantum theories on the Moyal plane. We develop quantum field theories invariant under the twisted action from the representations of the...

We prove a Poincaré lemma for a set of r smooth functions on a 2n-dimensional smooth manifold satisfying a commutation relation determined by r singular vector fields associated to a Cartan subalgebra of sp(2r, R). This result has a natural interpretation in terms of the cohomology associated to the infinitesimal deformation of a completely integrable system.

We show how Wigner's little group approach to the representation theory of Poincaré group may be generalized to the case of κ-deformed Poincaré group. We also derive the deformed Lorentz transformations of energy and momentum. We find that if the κ-deformed Poincaré group is adopted as the fundamental symmetry of nature, it results in deviations from predictions of the Poincaré symmetry at larg...

We introduce a novel and efficient simulation technique for generating physics-based skinning animations of skeleton-driven characters with full support for collision handling. Although physics-based approaches may use a volumetric (e.g. tetrahedral) flesh model, operations such as rendering, collision processing and user manipulation directly involve only the surface of this mesh. Motivated by...

We describe firstly the basic features of quantum κ-Poincaré symmetries with their Hopf algebra structure. The quantum κ-Poincaré framework in any basis relates rigidly the quantum κ-Poincaré algebra with quantum κ-Poincaré group, noncommutative space-time and κ-deformed phase space. Further we present the approach of Doubly Special Relativity (DSR) theories, which introduce (in the version DSR...
