in this paper the problem of 3d scene and object classification from depth data is addressed. in contrast to high-dimensional feature-based representation, the depth data is described in a low dimensional space. in order to remedy the curse of dimensionality problem, the depth data is described by a sparse model over a learned dictionary. exploiting the algorithmic information theory, a new def...

in this paper, we introduce and study the concept of $r$-fuzzy regular semi open (closed) sets in smooth topological spaces. by using $r$-fuzzy regular semi open (closed) sets, we define a new fuzzy closure operator namely $r$-fuzzy regular semi interior (closure) operator. also, we introduce fuzzy regular semi continuous and fuzzy regular semi irresolute mappings. moreover, we investigate the ...

residual ventricular septal defects (vsd) are major complications after cardiac surgery. we studied the incidence of this complication, risk factors for its occurrence and short-term follow-up in 179 pediatric patients that underwent surgical closure of vsd from april 2003 until may 2004. all data were gathered retrospectively except measurements of shunt ratio. studied risk factors included ag...

The first thing to note about these principles is that (as I will be understanding them), they are not merely classificatory principles for demarcating/separating cases of knowledge from non-knowledge. As I will be understanding (and using) them, (C) and (CC) are intended to be featured in epistemological explanations of why some agent S knows that Q (as opposed, e.g., to merely truly believing...

We introduce fuzzy closure systems and fuzzy closure operators as extensions of closure systems and closure operators. We study relationships between fuzzy closure systems and fuzzy closure spaces. In particular, two families F (S) and F (C) of fuzzy closure systems and fuzzy closure operators on X are complete lattice isomorphic.
