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-...

In order to study non cooperative IFF to technology, this paper detailed illustrates the D-S theory in a multi-sensor data fusion principle and target recognition method, calculation method and practical model is established. By applying the theory of evidence (D-S method), we can solve the problem of data fusion in multi-sensor conditions. Aiming at the problem of multi-sensor target recogniti...

The externally observable components of human actions carry only a tiny fraction of the information that matters. Human observers are vastly more interested in perceiving or inferring the mental states the beliefs, desires and intentions that lie behind the observable shell. If a person checks her watch, is she uncertain about the time, late for an appointment, or bored with the conversation? I...
