In this article we have studied the coverage optimization for 3G Long Term Evolution (LTE) according to Minimization of Drive Tests (MDT) work item description in Third Generation Partnership Project (3GPP). Target for the MDT work item is to define a set of measurements and measurement reporting procedures, so that operators are able to collect measurement data from users and thereby reducing need...
In this paper a new approach to the minimization of fuel consumption in Polymer Electrolyte Membrane (PEM) Fuel Cell (FC) systems is presented. It is mainly based on the minimization of the current produced by the FC by means of an adaptive technique, namely the Perturb and Observe (P&O) approach. The controller works in conjunction with the dc/dc converter which processes the power produced by...
