The electrical distribution network operation depends considerably on network busloads, which are formed by active and reactive power of the substations. Therefore, the network operation variables such as power flows, currents, voltages, etc. change similarly as do loads. It is possible to notice periodicity, temperature dependency, stochasticity etc. This paper describes the distribution netwo...

Monitoring network traffic on 10 Gbit networks requires very efficient tools capable of exploiting modern multicore computing architectures. Specialized network cards can accelerate packet capture and thus reduce the processing overhead, but they can not achieve adequate packet analysis performance. For this reason most monitoring tools cannot cope with high network speeds. We describe the desi...

Smart substation primary equipment on-line monitoring technology is an important part of the realization of substation intelligentizes monitoring. In order to meet the requirements of smart substation on high-speed, efficient, steady on-line monitoring system, the sharing of online monitoring data of the power station and to improve interoperability of on-line monitoring device, the primary equ...

this paper presents the application of radial basis neural networks to the development of a novel method for the condition monitoring and fault diagnosis of synchronous generators. in the proposed scheme, flux linkage analysis is used to reach a decision. probabilistic neural network (pnn) and discrete wavelet transform (dwt) are used in design of fault diagnosis system. pnn as main part of thi...

service availability is important for any organization. this has become more important with the increase of dos attacks. it is therefore essential to assess the threat on service availability. we have proposed a new model for threat assessment on service availability with a data fusion approach. we have selected three more important criteria for evaluating the threat on service availability and...

the paper discusses the current state of research concerning railway network timetabling and traffic management. timetable effectiveness is governed by frequency, regularity, accurate running, recovery and layover times, as well as minimal headway, buffer times and waiting times. analytic (queuing) models and stochastic microsimulation are predominantly used for estimation of waiting times and ...

The planning of publicly funded research and development programs can benefit from participatory foresight processes where research issues are evaluated with regard to multiple criteria. However, few approaches have been developed for the shaping of collaborative research networks through which the resulting priorities are implemented. We therefore develop a methodology for the joint shaping of...

Wireless transmission, a rising computer science field, has brought numerous applications and attracted the attention of many researchers in the past few years. For traffic monitoring systems, wireless transmission extends the traffic monitoring area more diffusely. Due to high demand in wireless traffic monitoring systems, how to optimize the system, to ensure timely and accurate data transmis...
