Individuals can now share real-time experiences at an unprecedented scale. Social Sensing: Building Reliable Systems on Unreliable Data looks at recent advances in the emerging field of social sensing, emphasizing the key problem faced by application designers: how to extract reliable information from data collected from largely unknown and possibly unreliable sources. The book explains how a myriad of societal applications can be derived from this massive amount of data collected and shared by average individuSocial mediaData processingInformation technologySocial mediaData processing.Information technology.302.30285Wang Dong596182Abdelzaher TarekKaplan LanceMiAaPQMiAaPQMiAaPQBOOK9910810570403321Social sensing3926911UNINA04327nam 22006735 450 991072838550332120230525122553.03-031-32394-710.1007/978-3-031-32394-2(MiAaPQ)EBC30552306(Au-PeEL)EBL30552306(OCoLC)1380845825(DE-He213)978-3-031-32394-2(BIP)090873157(PPN)270615040(CKB)26776194700041(EXLCZ)992677619470004120230525d2023 u| 0engurcnu||||||||txtrdacontentcrdamediacrrdacarrierAdvances in Active Bearings in Rotating Machinery Proceedings of The 1st Workshop on Active Bearings in Rotating Machinery (ABROM 2022), June 29-30, 2022, Athens, Greece /edited by Athanasios Chasalevris, Carsten Proppe1st ed. 2023.Cham :Springer International Publishing :Imprint: Springer,2023.1 online resource (218 pages)Lecture Notes in Mechanical Engineering,2195-4364Print version: Chasalevris, Athanasios Advances in Active Bearings in Rotating Machinery Cham : Springer International Publishing AG,c2023 9783031323935 1.Rotordynamic Modal Testing via Journal Bearing Lubricant Film – An Experimental Validation -- 2.Problems of Development of Tribotronics -- 3.A Presentation of Control Theory Applied to the Design of Controllable Segmented Gas Foil Bearings -- 4.Tilting-Pad Journal Bearing with Active Pads: A Way of Attenuating Rotor Lateral Vibrations -- 5.Studying the Effect of Viscous Friction Minimization in Actively Lubricated Journal Hybrid Bearings -- 6.On The Feedback Control of a Rotor System with Active Flexible Bearings -- 7.A novel monolithic shape-morphing bearing for real-time NVH control -- 8.Application of Squeeze film dampers -- 9.Investigation of Active Configuration in Gas Foil Bearings for Stable Ultra High-Speed Operation -- 10.Gyroid lattice structures for Tilting Pad Journal Bearings -- 11.Behavior of an Active Magnetic Bearing as a Stern Tube Bearing: A first approach via simulations -- 12.On the Stability Margins of Parametrically Excited Rotating Shafts on Gas Foil Bearings: Linear and Nonlinear Approach.This book reports on cutting-edge experimental and numerical findings related to the application of active bearings, including smart ones, in rotating machinery. It discusses their role in improving stability and control of rotor systems and reports in depth on the corresponding modeling and control approaches. Chapters are based on peer-reviewed contributions to the 1st Workshop on Active Bearings in Rotating Machinery (ABROM 2022), held on June 29- 30, 2022, in Athens, Greece, and organized in collaboration between the School of Mechanical Engineering of The National Technical University of Athens (NTUA) and the Faculty of Mechanical Engineering of Karlsruhe Institute of Technology (KIT). In connection with the increasing digital transformation of machine elements, this book offers a timely perspective and extensive information on testing methods and experimental procedures involved in the development of intelligent rotors for industrial applications.Lecture Notes in Mechanical Engineering,2195-4364Automatic controlMachineryDynamicsNonlinear theoriesControl and Systems TheoryMachinery and Machine ElementsApplied Dynamical SystemsMechanical EngineeringTechnology & EngineeringAutomatic control.Machinery.Dynamics.Nonlinear theories.Control and Systems Theory.Machinery and Machine Elements.Applied Dynamical Systems.621.406621.406Chasalevris Athanasios1362811Proppe Carsten1362812MiAaPQMiAaPQMiAaPQBOOK9910728385503321Advances in Active Bearings in Rotating Machinery3382344UNINA
