today, online social networks are very popular due to the possibility of creating relationships between people all over the world. these social networks with possibilities such as friend recommendation generally use local features derived from social graph structure. for friend recommendation, there are different algorithms with local and global approaches. in this paper, we proposed an algorit...

Respiratory burst induced bacteria killing by oxidants are important mechanism of host defence. However, it is impaired in tuberculosis due to inhibition of respiratory burst by Mycobacterial factors. Antioxidants are compounds that cause chelation of reactive oxygen species. So, antioxidants are expected to play a negative role in the management of active tuberculosis. But, oxidative stress is...

While Ising-type interactions are ideal for implementing controlled phase flip gates in one-way quantum computing, natural interactions between solid-state qubits are most often described by either the XY or the Heisenberg models. We show an efficient way of generating cluster states directly using either the imaginary SWAP (iSWAP) gate for the XY model, or the sqrt[SWAP] gate for the Heisenber...

Social network-based systems, also known as Friend-to-Friend (F2F) systems, are a promising approach to develop backup solutions that provide high reliability with a much lower consumption of bandwidth and storage than P2P ones. F2F backup systems can use two data redundancy strategies to handle peer failure events, namely: replication and erasure coding. In this paper we evaluate the use of th...

Trust models have been used widely in the literature in a number of different contexts. We examine an emotive scenario where trust would be extremely useful: online dating. We explore the use of a semiring-based trust model with online dating in a social network. Introductions are facilitated by friend-of-a-friend connections in the network in a manner similar to some real world scenarios. We s...

A routine activity of social networks’ servers is to recommend candidate friends that one may know and stimulate addition of these people to one’s contacts. An intriguing issue is how these recommendation lists are composed. This work investigates the main variables involved in the recommendation activity, in order to reproduce these lists including its time dependent characteristics. We propos...

Recently, social networks have attracted a particular interest in the web, particularly Facebook. Consequently, a large amount of social data is produced. For semantic modeling of such data, several social network ontologies are introduced. The most popular is FoaF (Friend of a Friend) ontology. In our research, we are interested in data generated from Facebook social network. Heretofore, the s...

With the rapid growth of user-created contents and wide use of community-based websites, content recommendation systems have attracted the attention of users. However, most recommendation systems have limitations in properly reflecting each user’s characteristics, and difficulty in recommending appropriate contents to users. Therefore, we propose a content recommendation method using Friend-Of-...
