In architectural and cultural heritage documentation, laser scanning technology today offers several opportunities to approach the object to study and to extract manifold information levels from it. These account for point-clouds, 3-D models, and other data about the state of conservation. Georeferenced point-clouds can be adopted as the spatial framework of a Space Information System for Archi...

The popularity and influence of reviews, make sites like Yelp ideal targets for malicious behaviors. We present Marco, a novel system that exploits the unique combination of social, spatial and temporal signals gleaned from Yelp, to detect venues whose ratings are impacted by fraudulent reviews. Marco increases the cost and complexity of attacks, by imposing a tradeoff on fraudsters, between th...

Abstract This paper proposes a graph-based mathematical approach with novel metric, the Structure Evolution Degree, to quantitatively analyze urban spatial structure transitions at cross scale and verifies its effectiveness through two cases studies, San Bartolomeo Quarter of Venice Xiaoxihu Historical Block Nanjing.

In this paper we propose a new decentralized algorithm to solve the consensus on the average problem on arbitrary strongly connected digraphs through a gossip algorithm based on broadcasts. We directly extend previous results by not requiring that the digraph is balanced. Our algorithm is an improvement respect to known gossip algorithms based on broadcasts in that the average of the initial st...
