    This paper presents an analytical model for the selection of the transmission power based on the bi-directional medium access information. Most of dynamic transmission power control algorithms are based on the single ...
  • Bogaers, Alfred EJ; Kok, S; Reddy, BD; Franz, T (2013-07)
    In recent years a great deal of advances have been made with respect to Dirichlet-Neuman (DN) partitioned fluid-structure interaction (FSI) solvers. Problems of varying degrees of complexity can be solved with reasonable ...
  • Scholes, B (2006-02)
    A group of researchers at the CSIR have been investigating the question “What controls the growth rate of trees in African savannas”? A combination of simple measurements taken in the field over long periods of time, with ...
  • Meyer, AA; Weerts, Steven P (2009-09)
    In this invited paper presented to the South Western Indian Ocean Fisheries Commission's fouth session, the trends in South Western Indian Ocean climatology have been evaluated for the 21st century. The scientific information ...
