In this paper we introduce a new Italian dataset consisting of simultaneous recordings of continuous speech and trajectories of important vocal tract articulators (i.e. tongue, lips, incisors) tracked by Electromagnetic Articulography (EMA). It includes more than 500 sentences uttered in citation condition by three speakers, one male (cnz) and two females (lls, olm), for approximately 2 hours o...

Abstract This paper studied the adsorption of chemical oxygen demand (COD), oil and turbidity produced water (PW) which accompanies production reconnaissance after treating utilizing powdered activated carbon (PAC), clinoptilolite natural zeolite (CNZ) synthetic type X (XSZ). Moreover, deals with comparison pollutant removal over different adsorbents. Adsorption was executed in a batch system. ...

In this paper a data miner based on the learning automata is proposed and is called LA-miner. The LA-miner extracts classification rules from data sets automatically. The proposed algorithm is established based on the function optimization using learning automata. The experimental results on three benchmarks indicate that the performance of the proposed LA-miner is comparable with (sometimes be...

For (c,,..., c„) in C, let C(cx,..., c„) denote the class of functions/(z) = 1 + cxz + ■ ■ • + cnz" + 2*>_„+ia*z* which are analytic and satisfy Re/(z) > 0 in the unit disc. The unique function of least H2 norm in C(cx,. .., c„) is explicitly determined. In this paper we consider a minimal interpolation problem at the origin, for the class H2 n C, where H2 denotes the well-known Hardy space for...

in this note we introduce the notion of weak mccoy rings as a generalization of mccoy rings, and investigate their properties. also we show that, if is a semi-commutative ring, then is weak mccoy if and only if is weak mccoy.

in this paper, we study some ring theoretic properties of the amalgamated duplication ring $rbowtie i$ of a commutative noetherian ring $r$ along an ideal $i$ of $r$ which was introduced by d'anna and fontana. indeed, it is determined that when $rbowtie i$ satisfies serre's conditions $(r_n)$ and $(s_n)$, and when is a normal ring, a generalized cohen-macaulay ring and finally a filter ring.

The number cn of weighted partitions of an integer n, with parameters (weights) bk, k ≥ 1, is given by the generating function relationship ∑∞ n=0 cnz n = ∏∞ k=1(1− zk)−bk . Meinardus(1954) established his famous asymptotic formula for cn, as n → ∞, under three conditions on power and Dirichlet generating functions for the sequence bk. We give a probabilistic proof of Meinardus’ theorem with we...

in this paper, we introduce a class of $j$-quasipolar rings. let $r$ be a ring with identity. an element $a$ of a ring $r$ is called {it weakly $j$-quasipolar} if there exists $p^2 = pin comm^2(a)$ such that $a + p$ or $a-p$ are contained in $j(r)$ and the ring $r$ is called {it weakly $j$-quasipolar} if every element of $r$ is weakly $j$-quasipolar. we give many characterizations and investiga...

in this paper, we investigate various kinds of extensions of twin-good rings. moreover, we prove that every element of an abelian neat ring r is twin-good if and only if r has no factor ring isomorphic to z2  or z3. the main result of [24] states some conditions that any right self-injective ring r is twin-good. we extend this result to any regular baer ring r by proving that every element of a...
