Evolution of Network Structure with a Fixed Number of Edges and Nodes Carissa Flocken June 2012 Abstract We consider a model that incorporates local rewiring of nodes and edges. We use a high-degree expansion in order to describe the first model that we believe would produce a power law with an exponential cuts off at the tail. However, we find that non-trivial correlations exist between degree...

In this paper we examine how remixing or content reuse is supported in a wide range of user-generated content websites. In particular, we analyzed the ways in which microblogging, social network, video, photo, music and scientific data sharing websites support some the following forms of content reuse: (a) Licensed content brought in from external sources. (b) Content uploaded to the website an...

In this paper, we report on our efforts to identify important Greek web sites on the web by analyzing the link structure of Greek web sites. Towards this end, five independent graph-theoretic methods have been deployed: hub and authority, page rank, Bow-Tie structure, core analysis and degree distribution. Our findings indicate that government, non-profit and educational sites are amongst the m...

Social networks and collaborative tagging systems are rapidly gaining popularity as a primary means for storing and sharing data among friends, family, colleagues, or perfect strangers as long as they have common interests. del.icio.us is a social network where people store and share their personal bookmarks. Most importantly, users tag their bookmarks for ease of information dissemination and ...

The 10th anniversary of the European Immunization Week (EIW) is celebrated between 20 and 25 April 2015 all over Europe [1]. This year, EIW focuses on the need for renewed commitment to immunisation at political, professional and personal levels. Various activities at national level are organised this week under the banner of EIW and they vary greatly from country to country. In some areas supp...

In this paper we introduce a model of spatial network growth in which nodes are placed at randomly selected locations on a unit square in R, forming new connections to old nodes subject to the constraint that edges do not cross. The resulting network has a power law degree distribution, high clustering and the small world property. We argue that these characteristics are a consequence of the tw...

In this paper, we studied the research areas of Chinese natural science basic research from a point view of complex network . Two research areas are considered to be connected if they appear in one fund proposal. The explicit network of such connections using data from 1999 to 2004 is constructed. The analysis of the real data shows that the degree distribution of the research areas network(RAN...

It appeared recently that some statistical properties of complex networks like the Internet, the World Wide Web or Peer-to-Peer systems have an important influence on their resilience to failures and attacks. In particular, scale-free networks (i.e. networks with power-law degree distribution) seem much more robust than random networks in case of failures, while they are more sensitive to attac...
