Power-associative antiflexible algebras have been studied by the author [3] and Kosier [2]. As a matter of terminology, we shall define an algebra as a finite dimensional vector space on which a multiplication is defined in which both distributive laws are satisfied. If A is an algebra over a field F of characteristic not two, then A has an attached algebra A + which is the same additive group ...

In this article, we evaluate the improvement in sign recognition that can be achieved with 3D tracking, compared to recognition with image plane tracking. Experiments are shown using a pair of stereo cameras, from which 3D positions of the segmented hands are estimated by triangulation between the left and right cameras. A sign classifier is trained on a set of 37 different NGT signs using 2D a...

Automatic speech processing systems are employed more and more often in real environments. Although the underlying speech technology is mostly language independent, differences between languages with respect to their structure and grammar have substantial effect on the recognition systems performance. In this paper, we present a review of the latest developments in the sign language recognition...

How, and to what extent, does the environment influence the way mutations interact? Do environmental changes affect both the sign and the magnitude of epistasis? Are there any correlations between environments in the variability, sign or magnitude of epistasis? Very few studies have tackled these questions. Here, we addressed them in the context of viral emergence. Most emerging viruses are RNA...

We discuss various mechanisms that can lead to interband sign reversal of the order parameter in a multiband superconductor. In particular, we generalize Abrikosov-Gor’kov solution of the problem of weakly coupled superconductor with magnetic and nonmagnetic impurities on the case of arbitary order parameter anisotropy, including extreme cases as d−pairing or interband sign reversal of the orde...

Nowadays many researches focus on the automatic recognition of sign language. High recognition rates are achieved using lot of training data. This data is, generally, collected by manual annotating SL video corpus. However this is time consuming and the results depend on the annotators knowledge. In this work we intend to assist the annotation in terms of glosses which consist on writing down t...

For a given isotropic and homogeneous field of magnetic fluctuations both the viscosity-α as well as the dynamo-α have been computed for accretion disks on the basis of a quasilinear approximation with shear flow and density fluctuations (i.e. magnetic buoyancy) included. The resulting viscosity-α proves to be positive for sufficiently strong shear (i.e. the angular momentum transport is outwar...

The purpose of this study was to examine the effects of message type and source on visitor compliance with fire restrictions at the Applewhite Picnic Area, Cajon Ranger District, San Bernardino National Forest, California. Six treatments were administered during summer 2005 involving verbal messages (awareness of consequences and altruistic messages) and signage for primarily Hispanic recreatio...
