• ON SOME PROPERTIES AND LIMITATIONS IN THE ISBN-13 CODE 

  Kamaku, P. Waweru; Kivunge, Bernard; Wangeci, Cecilia (2012)

  The International Standard Book Number system-13 (ISBN-13 ) is a thirteen digit code which uniquely identifies every book pub lished internationally. The code was formed as an improvement to the ISBN-10 code whic h ...
• Suborbits and Suborbital Graphs of the Symmetric Group acting on Ordered r-element Subsets 

  Rimberia, Jane; Kamuti, Ireri; Kivunge, Bernard; Kinyua, Francis (2013)

  The ranks and subdegrees of the symmetric group n S acting on [ ] r X , the set of all ordered r -element subsets from X have been studied (See Rimberia [4]). In this pape r, we examine ...
• Bounds for the Second Largest Eigenvalue of Real 3 × 3 Symmetric Matrices with Entries Symmetric about the Origin 

  Barini, Geoffrey; Kivunge, Benard; Akanga, Jotham (2012)

  Let ASn[a,b] denote a set of all real nxn symmetric matrices with entries in the interval [a,b]. In this article, we present bounds for the second largest eigenvalue λ2(A) of a real symmetric matrix A, such that A∈AS3 [-b,b].
• THE M_0 – MATRIX COMPLETION PROBLEM FOR DIGRAPHS OF 5×5 MATRICES WITH LESS THAN FOUR DIRECTED LINES 

  Njoroge, James Mwangi; Kivunge, Benard; Muondwe, Samuel Kanyi; Kinyanjui, Anthony Muthondu (2013)

  A real matrix is said to be – matrix if its principal minors are non - negative and all its non - diagonal entries are non - positive. In this project, we consider the – matrix completion ...
• Magnetic Hydrodynamic Free Convective Flow past an Infinite Vertical Porous Plate 

  Nyundo, Steven; Gatheri, K. Francis; Sigey, K. Johana (2012)

  A study of magnetic hydrodynamic free convective flow past an infinite vertical porous plate in an incompressible electrically conducting fluid is considered. The investigation of the effect of viscous dissipation on the ...
