This paper describes a technique for information mediation when multiple heterogeneous knowledge and data servers are to be accessed during query processing. One problem is building an intelligent interface between each knowledge server (KS) and its processor (KP); and the second is to provide interoper-ability among multiple KP/KS so that a query may be answered using information from multiple...

We perform a canonical quantization of gravity in a second-order formulation, taking as configuration variables those describing a 4-bein, not adapted to the space-time splitting. We outline how, neither if we fix the Lorentz frame before quantizing, nor if we perform no gauge fixing at all, is invariance under boost transformations affected by the quantization.

A field theory with local transformations belonging to the quantum group SUq(n) is defined on a classical spacetime. Gauge transformations for the potentials are given which lead to the appropriate quantum-group transformations for field strengths and covariant derivatives, and gaugeinvariant commutation relations are identified.

Quantitative Evaluation. We quantitatively evaluate the proposed long-term correlation tracking (LCT) algorithm on the 50 benchmark sequences with comparisons to the 11 state-of-the-art trackers, CSK [4], STC [10], KCF [5] MIL [1], Struck [3], CT [11], ASLA [6]), TLD [7], SCM [12], MEEM [9], and TGPR [2]). We report the distance precision at a threshold of 20 pixels in Table 1 and the overlap s...

Einstein’s Theory of General Relativity was formulated as a gauge theory of Lorentz symmetry by Utiyama in 1956, while the Einstein-Cartan gravitational theory was formulated by Kibble in 1961 as the gauge theory of Poincaré transformations. In a noncommutative space-time with canonical commutation relations between the coordintes, Lorentz symmetry is violated and field theories constructed on ...

The differential equations for a continuous birepresentation of a local analytic Moufang loop are established. The commutation relations for the infinitesimal operators of the birepresentation are found. These commutation relations can be seen as a (minimal) generalization of the Maurer-Cartan equations and do not depend on the particular birepresentation. 2000 MSC: 20N05, 17D10

This paper proposes two types of bilinear transformation spacebased speaker adaptation frameworks. In training session, transformation matrices for speakers are decomposed into the style factor for speakers’ characteristics and orthonormal basis of eigenvectors to control dimensionality of the canonical model by the singular value decomposition-based algorithm. In adaptation session, the style ...

We show that Buscher’s abelian duality transformation rules can be recovered in a very simple way by performing a canonical transformation first suggested by Giveon, Rabinovici and Veneziano. We explore the properties of this transformation, and also discuss some aspects of non-abelian duality.

This paper presents an algorithm for transforming closed planar curves into a canonical form, independent of the viewpoint from which the original image of the contour was taken. The transformation that takes the contour to its canonical form is a member of the projective group PGL(2), chosen because PGL(2) contains all possible transformations of a plane curve under central projection onto ano...
