No full textThis work investigates the applicability of an algorithm for real time estimation of flexible structural motions, using an innovative sensors setup in the field of active control technologies (ACT), particularly, gust load alleviation (GLA). The innovative proposal, presented in this paper, is the coupling of an active control function, based on an optimal state feedback control law, with an algorithm able to elaborate onboard sensor measurements for real time estimation of structural motion. Another innovative aspect of this paper concerns the proposed setup, which integrates inertial measurements of accelerometers and gyros with the output of a vision based system with a target LED, positioned in a suitable point of the aircraft. The effectiveness and potentialities of the proposed approach are verified through numerical simulations, performed using a complete aeroelastic model of a flexible UAV, and a realistic modeling of sensors included in the proposed setup

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
