The simulation results revealed that the robust Fisher’s approach based on the minimum covariance determinant estimates outperformed the other procedures; a good competitor to this technique is the winsorized probability base classification technique. Though, the robust Fisher’s technique using the minimum covariance determinant estimates breakdown for mixture contamination. On a general note, the conventional Fisher’s approach and the probability base technique performed comparable.</p> Fred zin ##submission.copyrightStatement## Thu, 03 Aug 2017 05:39:50 +0000 Totally Contact Umbilical Radical Transversal Lightlike Submanifolds Of An Almost Contact Manifold With B-Metric <p>In the present paper, we study the geometry of totally contact umbilical radical transversal lightlike submanifolds and totally contact umbilical CR- submanifold of an indenite Sasaki-like almost contact manifold with B-metric. We nd the necessary and sucient condition for the characterization of the induced connection to be a metric connection. Finally, we have proved that for a totally contact umbilical CR-submanifold, totally contact umbilical radical transversal lightlike submanifold is a totally geodesic radical transversal lightlike submanifold.</p> Anu Devgan, R.

(Pierre Laurent Wantzel, 1837),presented an algebraic proof based on ideas from Galois field showing that, the angle trisection solution correspond to an implicit solution of the cubic equation; , which he stated as geometrically irreducible [23]. The primary objective of this novel work is to show the possibility to solve the trisection of an arbitrary angle using the traditional Greek’s tools of geometry, and refutethe presented proof of angle trisection impossibility statement. The exposedproof of the solution is theorem , which is based on the classical rules of Euclidean geometry, contrary to the Archimedes proposition of usinga marked straightedge construction [4], [11].</p> Kimuya M Alex ##submission.copyrightStatement## Mon, 04 Sep 2017 03:13:58 +0000 Full-Discrete Weak Galerkin Finite Element Method for Solving Diffusion-Convection Problem. <p>This paper applied and analyzes full discrete weak Galerkin (WG) finite element method for non steady two dimensional convection-diffusion problem on conforming polygon. We approximate the time derivative by backward finite difference method and the elliptic form by WG finite element method. The main idea of WG finite element methods is the use of weak functions and their corresponding discrete weak derivatives in standard weak form of the model problem. The theoretical evidence proved that the error estimate in &nbsp;norm, the properties of the bilinear form, (v-elliptic and continuity), stability, and the energy conservation law.</p> Asmaa Hamdan ##submission.copyrightStatement## Fri, 06 Oct 2017 05:22:25 +0000 New Oscillation Criteria for Second Order Neutral Type Dierence Equations <p>In this paper, we present some new oscillation criteria for second order neutral type dierence equation of the form (an(zn)) + qnf(xn) = en; n n0 &gt; 0; where zn = xn 􀀀pnxn􀀀l and is ratio of odd positive integers.

The inhomogeneous Diophantine approximation of Groshev type on manifolds is studied. Major work is to discuss the inhomogeneous convergent theory of Diophantine approximation restricted to non-degenerate manifold in , based on the proof of Barker-Sprindzuk conjecture, the homogeneous theory of Diophantine approximation and inhomogeneous Groshev type theory for Diophantine approximation, by the decomposition of the set in manifold, with the aid of Borel Cantell lemma and transformation of lemma and its properties and the main inhomogeneous conversion principle, we know these two types of set in sense of Lebesgue measure is zero provided that the convergent sum condition is satisfied, from which several conclusions about the inhomogeneous convergent theory of Diophantine approximation is obtained. The main result is that Lebesgue measure is inhomogeneous strongly extremal. At last we use the fact that friendly measure is strongly contracting measure to develop an inhomogeneous strong extreme measure which is restricted to matrices with dependent quantities</p> Faiza Akram ##submission.copyrightStatement## Thu, 26 Oct 2017 08:48:56 +0000 Certain subclass of univalent functions involving fractional q-calculus operator <p>The main object of the present paper is to introduce certain subclass of univalent function associated with the concept of differential subordination.

This article is entirely based on symmetry.<br>Two symmetrical universes could have exactly the same mathematics, but differ in other respects.<br>The motivation for seeking symmetry inside quantum mathematics is that the QM picture of nature<br>is bizarre. Richard Feynman says no one can understand it. We propose that the quantum world is<br>not bizarre. QM portrays the wrong universe: the symmetrical one, not the one we inhabit. If<br>quantum waves travel in the opposite direction as what is expected, then we would have the same<br>math but a different universe, one that is recognizable and familiar. Wave equations are<br>symmetrical with respect to time reversal. This means they are symmetrical with respect to wave<br>direction reversal (with time going forwards). This wave equation symmetry is the basis of the<br>symmetry of two models of the universe, only one of which is congruent with the universe we<br>inhabit.</p> Jeffrey Boyd ##submission.copyrightStatement## Fri, 24 Nov 2017 05:04:35 +0000 Common Fixed Point Results for Compatible Map in Digital Metric Spaces <p>The aim of this paper is to define the concept of&nbsp; compatible maps and its variants in the setting of digital metric spaces and establish some common fixed point results for these maps.
