Precise Undersampling Theorems [PDF]

, 2010
Undersampling theorems state that we may gather far fewer samples than the usual sampling theorem while exactly reconstructing the object of interest-provided the object in question obeys a sparsity condition, the samples measure appropriate linear ...

Sobolev Type Decomposition of Paley-Wiener-Schwartz Space with Application to Sampling Theory [PDF]

, 2007
2000 Mathematics Subject Classification: 94A12, 94A20, 30D20, 41A05.We characterize Paley-Wiener-Schwartz space of entire functions as a union of three-parametric linear normed subspaces determined by the type of the entire functions, their polynomial ...

Approximation results in Orlicz spaces by modified sampling Kantorovich operators

Demonstratio Mathematica
This paper deals with the modified sampling Kantorovich operators. We start by presenting the primary notations of Orlicz spaces and fundamental auxiliary results.

Nonlinear sampling Durrmeyer operators: approximation results in function spaces

Advanced Nonlinear Studies
In this paper we introduce and study the nonlinear version of sampling Durrmeyer operators. For what concerns the space of continuous functions, a pointwise and uniform convergence theorem have been established.

, 2001
Myles Burnyeat maintains that Aristotelian epistêmê, in so far as it deals with explanations, is properly identified as understanding rather than as knowledge.

The Concept of Cause in Aristotle [PDF]

Aristotle distinguishes between four causes (Phy., B, 3; PsA, B, 11, 94a20-24): a) Material cause: that from which; the antecedent out of which a thing comes to be and persists. E.g. the bronze of the statue; the silver of the bowl b)
