Since available financial recourses are very limited, extending the lifespan of existing bridges, buildings and other infrastructures has become a major challenge to the engineering profession world-wide. Some of its related areas are only in their development phase. As the study of structural health assessment matures, more new areas are being identified to complement the concept. This book covers some of the most recent developments (theoretical and experStructural health monitoringStructural analysis (Engineering)Engineering inspectionElectronic books.Structural health monitoring.Structural analysis (Engineering)Engineering inspection.624.1/71Haldar Achintya1031574MiAaPQMiAaPQMiAaPQBOOK9910462815603321Health assessment of engineered structures2467813UNINA03441nam 22006015 450 991036660920332120251230061247.03-030-20040-X10.1007/978-3-030-20040-4(CKB)4100000008347163(MiAaPQ)EBC5785086(DE-He213)978-3-030-20040-4(PPN)258061723(EXLCZ)99410000000834716320190604d2020 u| 0engurcnu||||||||txtrdacontentcrdamediacrrdacarrierAdvances in Human Factors and Systems Interaction Proceedings of the AHFE 2019 International Conference on Human Factors and Systems Interaction, July 24-28, 2019, Washington D.C., USA /edited by Isabel L.

It describes advanced methodologies and tools for evaluating and improving interface usability and discusses new models, as well as case studies and good practices. The book addresses the human, hardware, and software factors in the process of developing interfaces for optimizing total system performance, while minimizing their costs. It also highlights the forces currently shaping the nature of computing and systems, such as: the importance of portability and technologies for reducing power requirements; the necessity of a better assimilation of computation in the environment; as well as solutions to promote accessibility to computers and systems for people with special needs. The book, which is based on the AHFE 2019 International Conference on Human Factors and Systems Interaction, held on July 24-28, 2019, in Washington D.C., USA, offers a timely survey and practice-oriented guide for systems interface users and developers alike.Advances in Intelligent Systems and Computing,2194-5365 ;959Cooperating objects (Computer systems)User interfaces (Computer systems)Human-computer interactionElectronicsArtificial intelligenceCyber-Physical SystemsUser Interfaces and Human Computer InteractionElectronics and Microelectronics, InstrumentationArtificial IntelligenceCooperating objects (Computer systems).User interfaces (Computer systems).Human-computer interaction.Electronics.Artificial intelligence.Cyber-Physical Systems.User Interfaces and Human Computer Interaction.Electronics and Microelectronics, Instrumentation.Artificial Intelligence.004.019004.019Nunes Isabel L.edthttp://id.loc.gov/vocabulary/relators/edtBOOK9910366609203321Advances in Human Factors and Systems Interaction1922154UNINA
