    To improve the collaboration between scientific communities working within geographically distributed laboratories, it is increasingly necessary to take into account the complexity of data streaming process and the difficulties with integrating heterogeneous instruments of different groups of researchers (Mongelli et al., 2017). This paper shows the 'ENEA staging storage sharing' (E3S) architecture developed within the COBRA project (http://cobra.enea.it/english) which promotes the technology transfer to small and medium-sized companies for the conservation of cultural heritage. This architecture was setup for the shaking tables at the Sustainable Innovation Technologies (SITEC) ENEA Casaccia R.C. Laboratory and it was used during experimental tests on two masonry walls made up of stone and tuff blocks that represent the poor Italian masonry of historical buildings, to verify the behaviour of innovative techniques of anti-seismic reinforcement. E3S supports the whole experimental process, from photogrammetric reconstruction to FEM calibration, reducing time needed to obtain experimental results by means real time data streaming functions

    Reference Chaser Bandwidth Controller for Wireless QoS Mapping under Delay Constraints

    No full text
    Telecommunications networks are composed of functional layers acting in cascade. Quality of Service (QoS) derives from the action of each layer that must assure a specific level of quality to the upper layer in terms of performance parameters (e.g., loss, delay, jitter of the packets). Appropriate algorithms are needed to compute the bandwidth necessary so to assure the requested QoS when information is transferred from one layer to the next one below. This paper proposes a scheme that adapts the bandwidth to be allocated to a buffer which conveys heterogeneous traffic (both concerning traffic sources and QoS requirements) in a layer-in-cascade model. The proposal is focused on delay constraints. The proposed algorithm is based only on measures and does not use closed-form expressions, a priori information about traffic statistical properties, and assumptions about buffer dimension. Simulation results show the reliability of the approach in comparison with other techniques at the state of the art, thus corroborating the application of the algorithm for a large set of operative situations, including fading conditions.</p
