The florentine Tommaso Cassai (1401-c.1427) 1 better known as Masaccio, has been hailed as the first great painter of the Italian Renaissance and his fresco Trinity (c.1425, Santa Maria Novella, Florence) as the first work of Western art that used full perspective. It appears that the author was inspired and actually helped by his friend Filippo Brunelleschi (1377-1446), the celebrated architec...
The theory of local homology modules was initiated by Matlis in 1974. It is a dual version of the theory of local cohomology modules. Mohammadi and Divaani-Aazar (2012) studied the connection between local homology and Gorenstein flat modules by using Gorenstein flat resolutions. In this paper, we introduce generalized local homology modules for complexes and we give several ways for computing ...
introduction: the critical dependence of healthcare services systems on information along with the indigenous restriction of paper documents in satisfying this need has caused a trend toward computer information systems. the main goal of such systems is to achieve electronic health records (ehr). however, implementation of ehr in healthcare organizations is difficult and complicated. this resea...
Recurrent neural networks have achieved remarkable success at generating sequences with complex structures, thanks to advances that include richer embeddings of input and cures for vanishing gradients. Trained only on sequences from a known grammar, though, they can still struggle to learn rules and constraints of the grammar. Neural Attribute Machines (NAMs) are equipped with a logical machine...
In this paper, we study generalized Douglas-Weyl Finsler metrics. We find some conditions under which the class of generalized Douglas-Weyl (&alpha, &beta)-metric with vanishing S-curvature reduce to the class of Berwald metrics.
We discuss the relic density of the lightest of the supersymmetric particles (LSP) in view of new cosmological data, which favour the concept of an accelerating Universe with a non-vanishing cosmological constant. The new bound on the Cold Dark Matter density, ΩCDMh 2 0 . 0.22, puts stringent constraints on supersymmetry preferring low supersymmetry breaking scales, in sharp contrast to electro...
Hartle’s generalized quantum mechanics in the sum-over-histories formalism is used to describe a nonabelian gauge theory. Predictions are made for certain alternatives, with particular attention given to coarse-grainings involving the constraint. In this way, the theory is compared to other quantum-mechanical descriptions of gauge theories in which the constraints are imposed by hand. The vanis...
In this paper we introduce two different representation approaches and propose two techniques to estimate the position of vanishing points in an image, one based on a probabilistic strategy and the other focused on a deterministic analysis. Unlike most of the methods so far developed, which exploit the Gaussian sphere, the new techniques operate in the (ρ, θ) polar parameter space and in the (x...
We present a novel perception-driven approach to low-cost tele-presence systems, to support immersive experience in continuity between projected video and conferencing room. We use geometry and spectral correction to impart for perceptual continuity to the whole scene. The geometric correction comes from a learning-based approach to identifying horizontal and vertical surfaces. Our method redra...
We present a method for the automatic detection of vanishing points in urban scenes based on finding point alignments in a dual space, where converging lines in the image are mapped to aligned points. To compute this mapping the recently introduced PClines transformation is used. A robust point alignment detector is run to detect clusters of aligned points in the dual space. Finally, a post-pro...
