The ever increase of nonlinear loads in electric distribution networks causes many problems due to the high level of harmonic currents. This paper proposes a new technique for controlling a single phase shunt active power filter based on a selective compensation using the newly developed technique of harmonic control arrays. Simulation results confirm the appropriate selective harmonic compensa...

in the last decade, many applied common studies were done in economic social systems phenomena by using network analysis. in these studies, trade relations can be considered as a network that each vertex represents a country and the trade relations between countries represent links of this network. first, we try to make the world exporting and importing networks based on the existence data for ...

This paper generalizes known results for nonblocking distribution networks also known as generalized connection networks to the mul tirate environment where di erent user connec tions share a switch s internal data paths in arbi trary fractions of the total capacity In particular we derive conditions under which networks due to Ofman and Thompson Pippenger and Turner lead to multirate distribut...

Directed acyclic graphs (DAGs) are a popular framework to express multivariate probability distributions. Acyclic directed mixed graphs (ADMGs) are generalizations of DAGs that can succinctly capture much richer sets of conditional independencies, and are especially useful in modeling the effects of latent variables implicitly. Unfortunately, there are currently no parameterizations of general ...

One of the key factors affecting leakage in water distribution systems is network pressure management by putting Pressure Reduce Valves (PRV) in the flow path and optimal regulation of these vales in water networks. This study aimed at investigating optimal pressure management problems so as to minimize leakage in water distribution networks. To do so, an approach was proposed for both optimal ...

Future entertainment services are expected to be increasingly interactive, on demand and personalized. This paper aims to address the challenge of provisioning network and server resources to support the distribution of these services over the Internet. We propose the Overlay Distribution Network (ODN) as a cost-effective means to deliver these services. Because ODNs are created over shared net...
