Operational Mode and Slicing Adaptation in OpenConfig Disaggregated Optical Networks
No full textThis paper proposes and experimentally validates a workflow to handle network failures implying the change of the operational mode on optical OpenConfig transponders. An SDN control plane is considered with a real packet-optical data plane
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Blockchain-Anchored Failure Responsibility Management in Disaggregated Optical Networks
No full textA novel framework based on blockchain is proposed to provide trusted SLA accounting. Extensions to SDN ONOS controller successfully assess controversial SLA degradations responsibilities upon failure events in a multi-vendor OpenROADM-based white box scenario
Experimental analysis and optimization to maximize ultimate tensile strength and ultimate elongation of friction stir welded aa6082 aluminum alloy
No full textFriction stir welding (FSW) is a well-established welding technique, which allows joining abutting surfaces by generating heating through a rotating and translating tool specifically shaped. Differently from the conventional techniques, continuous welding processes can be executed by FSW, thus supporting the economy of scales objectives. This paper deals with the selection of the optimal process parameters for the FSW of the AA6082 aluminum alloy. Three welding parameters, namely tool plunging, rotational speed and welding speed, have been handled as independent variables for developing two mathematical models by means of a non-linear regression-based approach, with the aim of predicting both ultimate tensile strength and ultimate elongation of the welded joints. A set of additional experimental tests has been used to validate the mentioned metamodels and finally three different metaheuristic algorithms have been implemented for selecting the best process parameters able to maximize the aforementioned mechanical properties. A comparison analysis based on further experimental tests confirmed the accuracy of the predicting metamodels and the quality of solutions yielded by the proposed optimization approaches
