Abstract In the context of determination and implementation dual carbon goal, it is an important trend China’s energy strategy to incorporate a considerable proportion renewable into power grid. Therefore, consumption gradually turning new sources such as wind energy. Considering limitations random, intermittent anti-peak regulation forms light, multi-objective optimization model wind, fire sto...

In this paper we investigate a technique for fusing approximate knowledge obtained from distributed, heterogeneous information sources. We use a generalization of rough sets and relations [14], which depends on allowing arbitrary similarity relations. The starting point of this research is [2], where a framework for knowledge fusion in multi-agent systems is introduced. Agent’s individual perce...

The widespread diffusion of mobile communication systems is paving the way for new information services to be provided to users. This paper deals with the Personalised Access to Local Information and services for tOurists (PALIO-IST 20656) Project within the fifth research framework of the European Commission. The focus is on tourists that need to access information on the city or on the region...

This study relates to the imaging of noise sources that are distributed and strongly directional, such as in turbulent jets. The goal is to generate noise source maps that are self-consistent, i.e., their integration over the extent of the noise source region gives the far-field pressure autospectrum for a particular emission direction. This is possible by including a directivity factor in the ...

Querying large numbers of data sources is gaining importance due to increasing numbers of independent data providers. One of the key challenges is executing queries on all relevant information sources in a scalable fashion and retrieving fresh results. The key to scalability is to send queries only to the relevant servers and avoid wasting resources on data sources which will not provide any re...

Abstract Helicon plasma sources are known to be efficient generators of high-density plasma for materials processing applications. By using multiple sources, arbitrarily large substrates can in principle be covered uniformly with dense plasma. To test this idea, a seven-tube helicon source was constructed, and the plasma density and uniformity measured. Densities up to 1012 cm−3 over a 40 cm di...

We consider the distributed source coding system of L correlated Gaussian sources Yl, l = 1, 2, · · · , L which are noisy observations of correlated Gaussian remote sources Xk, k = 1, 2, · · · ,K. We assume that Y L = (Y1, Y2, · · · , YL) is an observation of the source vector X = (X1, X2, · · · , XK), having the form Y L = AX+N, where A is a L×K matrix and N = (N1, N2, · · · , NL) is a vector ...

In this paper we present robust algorithms of transmission and reconstruction of attacking path(s) in IDS for providing traceback information in IP packets without requiring interactive operational support from Internet Service Providers, which is based on IP address compression techniques, polynomial theory and techniques from algebraic coding theory. Our best scheme has improved robustness ov...

In antenna array applications, the propagation environment is often more complicated than the ordinary assumption of plain wavefronts. Here, a low complexity algorithm is suggested for estimating both the DOA and the spread angle of a mobile source subject to local scattering, using a uniform linear array. The parameters are calculated from the estimates obtained using a standard algorithm such...
