    • Developing Secant Method for Solving Nonlinear Equations 

      Iskandar, Taufiq; Marlan, Marlan; Gultom, Sanggam P; Mawengkang, Herman (Proceedings of The 5th IMT-GT International Conference of Mathematics, Statistics, and Their Applications (ICMSA 2009), June 09-11, 2009, Bukittinggi, 2009-06-09)
      In this paper we develop secant methods for nonlinear system using a population of previous iterates. Contrarily to classic secant methods, where exact interpolation is used, we prefer a least square approach to calibrate ...

    • A Discreate Optimization Model for Designing Cellular Networks Considering Electromagnetic Radiation 

      Hutauruk, Sindak; Mawengkang, Herman; Baafai, Usman; Noor, Nasruddin (International Journal of Computer Trends and Technology, 2015-10-01)
      The boom in demand for mobile phone throughout the world is causing a constant increase in the BTS (Base Transceiver Station) number, particularly in Medan city. Such increase aims at achieve a better spatial frequency ...
