This article aims at showing some potential applications of geomatics to works in which both excavation and restoration are carried out simultaneously, so that the three-dimensional layout of the monu...
THE MONUMENTS RESTORATION YARD: A VIRTUALIZATION METHOD AND THE CASE OF STUDY OF SALA DELLE CARIATIDI IN PALAZZO REALE, MILAN
Cultural Heritage Laser Scanning Close-range photogrammetry Virtual Reality Visualization Real-time
2015/8/7
In this paper we present a method for applying VR techniques to simulate and analyze restoration projects of architectural
monuments, starting from real world data. Our method is meant as a visualiz...
A network design technique for selective restoration
network design technique selective restoration
2011/5/25
We outline a network design technique that exploits differences in the failure rate and impact of network elements to produce a more efficient design. We demonstrate its efficacy on a Tier-1 backbone ...

A centralized impairment-aware lightpath restoration scheme is experimentally demonstrated. Through the implementation of the QoT estimator module on FPGA technology,restoration times of 1.36s are ach...
Multi-failure Restoration Demonstrations with Multi-vendor Interoperability in Control Plane enabled WSON
Multi-failure Restoration Demonstrations Multi-vendor Interoperability Control Plane enabled WSON
2011/5/18
We demonstrate multi-failure restoration in optical layer by using an eleven-node mul-ti-vendor WSON test-bed. Automatic restoration is achieved by deploying colorless and direction-less optical switc...
Experimental validation of end-to-end GMPLS-enabled restoration in multi-domain transparent WSON
Networks protection restoration
2010/6/5
Two GMPLS restoration strategies operating at wavelength and link granularities are experimentally validated in a multi-domain WSON. The strategies are qualitatively compared in terms of resource usag...
