  • Two- Phase Stratified Sampling Estimator for Population Mean in The
           Presence of Nonresponse Using Single Auxiliary Variable

    • Authors: Akan Anieting (Author
      Abstract: In this article, a new estimator for population mean in two-phase stratified sampling in the presence of nonresponse using single auxiliary variable has been proposed. The bias and Mean Squared Error (MSE) of the proposed estimator has been given using large sample approximation. The empirical study shows that the MSE of the proposed estimator is more efficient than existing estimators. The optimum values of first and second phase sample have been determined.

  • A New Proof of the Lester’s Perimeter Theorem in Euclidean Space

    • Authors: Oğuzhan Demirel; Leyla Aslan, Damla TOPAL (Author
      Abstract: An injection defined from Euclidean space  n-space E^n to itself which preserves the triangles of perimeter 1 is an Eucldean motion.   J. Lester gave two different proofs for this theorem in Euclidean plane [1] and Euclidean space [2]. In this study a new technique is developed for the proof of this theorem which is valid in both Euclidean plane  and Euclidean space.

  • Stability Analysis of the Corruption Free Equilibrium of the Mathematical
           Model of Corruption in Nigeria

    • Authors: Victor Akinsola; ADEYEMI BINUYO (Author
      Abstract: In this paper, a mathematical model of the transmission dynamics of corruption among populace is analyzed. The corruption free equilibrium state, characteristic equation and Eigen values of the corruption model were obtained. The basic reproductive number of the corruption model was also determined using the next generation operator technique at the corruption free equilibrium points. The condition for the stability of the corruption free equilibrium state was determined. The local stability analysis of the mathematical model of corruption was done and the results were presented and discussed accordingly. Recommendations were made from the results on measures to reduce the rate of corrupt practices among the populace.

  • Scientific Numerical Pattern in Stringed-Fretted Musical Instrument

    • Authors: Anindita Roy Chowdhury; Naresh Sharma (Author
      Abstract: Music, a creative art has a strong foundation on science and mathematics. Source of music can vary from vocal chord to various types of musical instruments. One of the popular stringed and fretted musical instrument, the guitar has been discussed here. The structure of the guitar is based on mathematical and scientific concepts. Harmonics and frequency play pivotal role in generation of music from a guitar. In this paper, the authors have investigated various factors related to the structure of a guitar. Aspects related to the musical notes of a guitar have been analyzed to gain a better insight into the mathematical pattern involved in the music of a guitar.

  • On The Numerical Solutions of Boundary Layer Equations of Williamson Fluid
           Past a Moving Plate

    • Authors: Manisha Patel; Jayshri Patel, M.G.Timol (Author
      Abstract: Laminar boundary layer flow of Williamson fluid over a moving plate is discussed in this paper. The governing equations of the flow problem are transformed into similarity equations using similarity technique. The reduced equations are numerically solved by finite difference method. The graphical presentation is discussed.
