Description: With the development of power systems and the
extensive application of nonlinear elements in the electricity
system, the problem of ferroresonance do harm to the network
and electricity facilities has become more prominent. Wavelet
analysis has good time-frequency localization characteristic, so it
is suitable for fault analysis of power system. This paper is base
on in the neutral point unearthed system, which is excited by
single phase grounding fault, take analysis of the value of neutral
point with the Daubechies wavelet analysis. Simulation results
show that with wavelet transforms the occurrence of Ferro
resonance time can be detected and the frequency resonance can
also be determined.

Description: These days, optical networks worldwide have been widely deployed in various network scales,
including long-haul backbone and metropolitan areas, as well as regional broadband access. In order
to assure a certain quality of service and a service-level agreement of the data delivery as requested
by the network service subscribers, network management plays a very important role in the operation
and administration of practical optical networks. Performance management is among the key aspects of
network management that assures the signal quality during signal transmission, switching, and routing.
It provides several important network functions including (1) providing feedback in the adaptive signal
compensators and equalizers (2) control of network elements (3) link setup, control, and optimization
and (4) fault forecasting, detection, diagnosis, and localization, as well as resilience mechanism

Description: In this paper, we propose a robust and low-complexity
acoustic source localization technique based on time differences of
arrival (TDOA), which addresses the scenario of distributed sensor
networks in 3D environments. Network nodes are assumed to be
unsynchronized, i.e., TDOAs between microphones belonging to
different nodes are not available. We begin with showing how to
