    • Mathematical model for outgassing and contamination 

      Shillor, Meir (1991-10)
      A model for the mathematical description of the processes of outgassing and contamination in a vacuum system is proposed. The underlying assumptions are diffusion in the source, convection and diffusion in the cavity, mass ...
    • Curves of genus 2 with (n, n)--decomposable Jacobians 

      Shaska, Tony (Journal of Symbolic Computation, 2001-05)
      Let C be a curve of genus 2 and ψ1: C − → E 1 a map of degree n, from C to an elliptic curveE1 , both curves defined over C. This map induces a degree n map φ1:P1 − → P 1 which we call a Frey–Kani covering. We determine ...
    • Dynamic contact with normal compliance wear and discontinuous friction coefficient 

      Shillor, Meir (2002-08)
      We apply the recent theory of evolution inclusions forset-valued pseudomonotone maps, developed in Kuttler and Shillor[Commun.Contemp.Math.,1(1999),pp.87–123]to the problem of dynamic frictional contact with normal compliance ...

      Oakley, B; Hanna, D; Shillor, Meir; Barber, G (2003-09)
      Polynomial expressions for the speed of sound as a function of pressure for 68 different organic liquids are presented in tabular form. The liquids form a subset of those discussed in the companion paper: Ultrasonic ...

      Existence of a weak solution for the problem of dynamic frictional contact between a viscoelastic body and a rigid foundation is established. Contact is modelled with the Signorini condition. Friction is described by a ...

      Shaska, Tony; Wang, Quang (2006-01-15)
      We study Ca,b curves and their applications to coding theory. Recently, Joyner and Ksir have suggested a decoding algorithm based on the automorphisms of the code. We show how Ca,b curves can be used to construct MDS ...
    • A one-dimensional spot welding model 

      Andrews, K.T.; Guessous, L.; Nassar, S.; Putta, S.V.; Shillor, Meir (2006-11)
      A one-dimensional model is proposed for the simulations of resistance spot welding, which is a common industrial method used to join metallic plates by electrical heating. The model consists of the Stefan problem, in ...
    • Special issue on algebra and computational algebraic geometry 

      Elezi, Artur; Shaska, Tony (Albanian J. Math., 2007-12)
      Algebraic geometry is one of the main branches of modern mathematics with roots from classical Italian geometers. Its modern flavor started with Grothendieck and continued with many illustrious algebraic geometers of the ...
    • A frictional contact problem for an electro-viscoelastic body 

      Lerguet, Zhor; Shillor, Meir; Sofonea, Mircea (2007-12)
      A mathematical model which describes the quasistatic frictional contact between a piezoelectric body and a deformable conductive foundation is studied. A nonlinear electro-viscoelastic constitutive law is used to model the ...
    • Some open problems in computational algebraic geometry. 

      Shaska, Tony (Albanian J. Math., 2007-12-15)
      The development of computational techniques in the last decade has made possible to attack some classical problems of algebraic geometry from a computational viewpoint. In this survey, we briefly describe some open ...
    • Thetanulls of cyclic curves of small genus 

      Previato, Emma; Shaska, Tony; Wijesiri, Sujeeva (Albanian J. Math., 2007-12-15)
      We study relations among the classical thetanulls of cyclic curves, namely curves $\X$ (of genus $g(\X )>1$ ) with an automorphism $\s$ such that $\s$ generates a normal subgroup of the group $G$ of automorphisms, and $g ...
    • Regularity result for the problem of vibrations of a nonlinear beam 

      M'Bengue, M.F.; Shillor, Meir (2008-02)
      A model for the dynamics of the Gaonon linear beam, which allows for buckling, is studied. Existence and uniqueness of the local weak solution was established in Andrews et al. (2008). In this work the further regularity ...
    • Dynamic contact of two GAO beams 

      Ahn, Jeongho; Kuttler, Kenneth; Shillor, Meir (2012-11)
      The dynamic contact of two nonlinear Gao beams that are connected with a joint is modeled, analyzed, and numerically simulated. Contact is modeled with either (i) the normal compliance condition, or (ii) the unilateral ...

      Izquierdo, Milagros; Shaska, Tony (eprint arXiv:1501.01559, 2014-11-15)
      In this paper we study the automorphism groups of real curves admitting a regular meromorphic function f of degree p, so called real cyclic p-gonal curves. When p = 2 the automorphism groups of real hyperelliptic curves ...
