Burt introduced 1983 'equivalent weighting function': \Iterative pyramid generation is equivalent to convolving the image g 0 with a set of 'equivalent weighting functions' h l :" g l = h l g 0 = h g l?1 ; l > 1. It allowed him to study the eeects of iterated reduction (e.g. the low-pass character of Gaussian pyramids) using the single parameter h l without giving up the eecient iterative compu...

A Rota-Baxter Leibniz algebra is a $(\mathfrak{g},[~,~]_{\mathfrak{g}})$ equipped with operator $T : \mathfrak{g} \rightarrow \mathfrak{g}$. We define representation and dual of algebras. Next, we cohomology theory also study the infinitesimal formal deformation algebras show that our cohomology. Moreover, an abelian extension equivalence classes such extensions are related to groups.

OBJECTIVE The aim of this study was to evaluate the morphology of glass (GF), carbon (CF) and glass/carbon (G/CF) fiber posts and their bond strength to self or dual-cured resin luting agents. MATERIAL AND METHODS Morphological analysis of each post type was conducted under scanning electron microscopy (SEM). Bond strength was evaluated by microtensile test after bisecting the posts and re-bo...

The submodular flow (SF) problem, introduced by Edmonds and Giles [6], is a general network flow problem, where net flows into subsets of nodes are restricted by submodular set constraints. Suppose that we are given (i) a directed graph G = (V, E) with node set V and arc set E, (ii) a submodular function b" on a crossing family ,~-", (iii) lower and upper capacity functions f a n d g where f : ...
