  • A quasar sample for the Lyα forest studies from the Data Release 10 of the Sloan Digital Sky Survey 
    Torbaniuk, O. (Advances in Astronomy and Space Physics, 2015)
    We present a new sample of the z ≥ 2 quasar spectra. It contains 102 643 spectra which were visually selected from the SDSS DR10, and includes also a subsample of 65 976 spectra for the composite spectra compilation. This ...
  • A Quasi-Lie Schemes Approach to Second-Order Gambier Equations 
    Cariñena, J.F.; Guha, P.; de Lucas, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2013)
    A quasi-Lie scheme is a geometric structure that provides t-dependent changes of variables transforming members of an associated family of systems of first-order differential equations into members of the same family. In ...
  • Aquation of impurity distribution in a solid distillate 
    Kravchenko, A.I. (Functional Materials, 2006)
    An equation has been derived describing the distribution of an impurity in a distillate obtained by vapor condensation into solid phase at a low impurity content and under ideal mixing of the substance being distilled.
  • A Queueing Approach in Determining Optimal Numberof Beds in a Hospital Serving Urgent and Non-Urgent Patients 
    Abolnikov, L.; Zachariah, T.M. (Электронное моделирование, 2010)
    In this paper, the authors consider a hospital as a multichannel queueing system that serves two different arriving Poisson flows of urgent and non-urgent customers (patients). The distribution of the service time is assumed ...
  • A Ramsey algebraic study of matrices 
    Teoh, Z.Y.; Teh, W.C. (Algebra and Discrete Mathematics, 2019)
    The notion of a topological Ramsey space was introduced by Carlson some 30 years ago. Studying the topological Ramsey space of variable words, Carlson was able to derive many classical combinatorial results in a unifying ...
