In spite of its almost photographic realism, the Arnolfi ni Portrait by naturalistic painter Jan van Eyck exhibits faulty linear perspective. This paper describes the creation of a three-dimensional virtual reconstruction of the painting’s interior scene using commercial modelling and image processing software. The result presented here is a rendering of the reconstructed scene closely resembli...

We consider the deformed Poincare group describing the space-time symmetry of noncommutative field theory. It is shown that the deformed symmetry is equivalent to explicit symmetry breaking. PACS number(s): 11.10-z, 11.30Cp

The κ−Poincare group and its algebra in an arbitrary basis are constructed. The κ−deformation of the Weyl group and its algebra in any dimentions and in the reference frame in which g00 = 0 are discussed.

Relativistic Gamow vectors were originally obtained from the Smatrix pole term for resonance formation experiments. They furnish an irreducible representation of the Poincare semi-group in the forward light cone and are characterized by spin and the complex pole position, very much like stable relativistic particles are labeled by spin and mass, and defined by Wigner’s basis vectors of unitary ...

In this paper, homotopy perturbation and modified Lindstedt-Poincare methods are employed for nonlinear free vibrational analysis of simply supported and double-clamped beams subjected to axial loads. Mid-plane stretching effect has also been accounted in the model. Galerkin's decomposition technique is implemented to convert the dimensionless equation of the motion to nonlinear ordinary differ...

Electrocardiogram is the recording of the electrical potential of heart versus time. The analysis of ECG signal has great importance in the detection of cardiac abnormalities. In this paper we have dealt about the removal of noises in ECG signals and arrhythmia classification of the signal.The inputs for our analysis is taken from MIT-BIH database (Massachusetts Institute of Technology Beth Isr...

Abstract: We introduce a dual lifting of unified gauge theories, the We introduce a dual lifting of unified gauge theories, the first characterized by the isotopies, which are axiompreserving maps into broader structures with positive-definite generalized units used for the representation of matter under the isotopies of the Poincare’ symmetry, and the second characterized by the isodualities, ...

The smart OGY control method is proposed for two-link rigid robot arm. For this goal the Bifurcation diagram should be applied for acceptable wide range of the input amplitude. Then by using the robot arm in a chaotic amplitude range and Poincare section, the UPO's will be found. After that, the OGY rules are defined for each UPO's and the maximum changed value of amplitude for each UPO's, whic...
