In this paper, a new model of phytoplankton growth in the chemostat is proposed. First, we give a description of the chemostat and we recall the main models: the simple Monod model, experimentally validated for bacteria growth and the Droop model, which is validated for phytoplankton growth and takes into account the possible nutrient storage. Though our model is quite similar to the Droop one,...

In this paper, we propose a real-time admission control mechanism in conjunction with revenue optimization for DS-CDMA network. For solving the optimization problem, iteration-based Lagrangean relaxation approach is applied by allocating a time budget. The achievement in terms of problem formulation and performance analysis is presented. Associated parameters considered are mean arrival rate, m...
