On the Impact of Wireless Jamming on the Distributed Secondary Microgrid Control

open access: yes, 2016
The secondary control in direct current microgrids (MGs) is used to restore the voltage deviations caused by the primary droop control, where the latter is implemented locally in each distributed generator and reacts to load variations.

Uncovering the Local Hidden Community Structure in Social Networks [PDF]

open access: yesarXiv, 2021
Hidden community is a useful concept proposed recently for social network analysis. To handle the rapid growth of network scale, in this work, we explore the detection of hidden communities from the local perspective, and propose a new method that detects and boosts each layer iteratively on a subgraph sampled from the original network. We first expand

Intelligent OFDM telecommunication system. Part 4. Anti-eavesdropping and anti-jamming properties of the system, based on many-parameter and fractional Fourier transforms [PDF]

open access: yes, 2019
In this paper, we aim to investigate the superiority and practicability of many-parameter wavelet and Golay transforms (MPWT and MPGT) from the physical layer security (PHY-LS) perspective.

Bayesian Overlapping Community Detection in Dynamic Networks [PDF]

open access: yesarXiv, 2016
Detecting community structures in social networks has gained considerable attention in recent years. However, lack of prior knowledge about the number of communities, and their overlapping nature have made community detection a challenging problem. Moreover, many of the existing methods only consider static networks, while most of real world networks ...

Uncovering Complex Overlapping Pattern of Communities in Large-scale Social Networks [PDF]

open access: yes, 2018
The conventional notion of community that favors a high ratio of internal edges to outbound edges becomes invalid when each vertex participates in multiple communities. Such a behavior is commonplace in social networks. The significant overlaps among communities make most existing community detection algorithms ineffective.

Joint Radar Jamming and Communication System Design Based on Universal Filtered Multicarrier Chirp Waveform

open access: yesRemote Sensing
In this article, we propose a joint waveform based on universal filtered multicarrier (UFMC) chirp for radar jamming and communication joint systems. Modulation of radar jamming chirp signals and communication signals on different subcarrier groups in ...

Characters and patterns of communities in networks [PDF]

open access: yesarXiv, 2013
In this paper, we propose some new notions to characterize and analyze the communities. The new notions are general characters of the communities or local structures of networks. At first, we introduce the notions of internal dominating set and external dominating set of a community.
