The recent initiative of Network Functions Virtualization (NFV) aims to deliver any data- plane processing or control-plane function in high volume data centers or network elements to decrease operational cost and increase deployment flexibility. In order to dynamically direct traffic flows between respective network elements, Software Defined Networking(More)
This demonstration shows how Network Function Virtualisation (NFV) [1] can be used by a network provider to dynamically provide required mobile core network functions in case of a large ”Mega” event like a soccer game or a music festival. Economical reasons may not justify the installation or continuous maintenance of expensive dedicated hardware which is(More)
In this paper, a lightweight ironless axial flux permanent magnet drive concept is presented. The in-wheel hub motor has a high torque to weight ratio and achieves a high efficiency, which extends the operation range of battery powered vehicles. The steps from preliminary design to manufacturing of the components are described. The paper includes Finite(More)
Using an alternative approach for evaluating the Bit-Error Rate (BER), we present a numerical and experimental investigation of the performance of phase-modulated optical communication systems in the presence of nonlinear phase noise and dispersion. The numerical method is based on the well known Karhunen-Lo;eve expansion combined with a linearization(More)
