It connects the extensive early literature on self-focusing, filamentation, self-trapping, and collapse with more recent studies aimed at issues such as self-focusing of femtosecond pulses, white light generation, and the generation of filaments in air with lengths of more than 10 km. It also describes some modern advances in self-focusing theory including the influence of beam nonparaxiality on self-focusing collapse. In addition, this text reprints three key articles in the field, as well as the paper that describes the first laboratory observation of self-focusing phenomena with photographic evidence. Self-focusing: Past and Present is of interest to scientists and engineers working with lasers and their applications, as well as students, researchers, and laser and eye surgeons.Topics in applied physics ;v. 114.Laser beamsNonlinear opticsLaser beams.Nonlinear optics.621.36/6UD 2020rvkUH 5680rvkBoyd Robert W.1948-45219Lukishova Svetlana G1757787Shen Y.

Early detection of damage and accurate assessment of structural safety requires monitoring systems, the data from which can be used to calibrate numerical models for structural analysis and to assess safety. Data are obtained under real-time conditions, considering a group of parameters related to structural properties, such as stresses, accelerations, deformations and displacements. The analysis of structural properties is particularly relevant when the structure is subjected to extreme events (earthquakes, wind, fire and explosions, among others) or repeated loads (road/rail/air traffic, vibrations induced by equipment and machines), since they affect the structural integrity and put the users at risk. In order to prevent the severe damage and eventual collapse of structures, and consequent human, material and economic losses, the implementation of monitoring systems becomes a valuable tool for today's society. Monitoring of structures is becoming increasingly important, not only as preventive action, but also due to actual economic and sustainability concerns, to ensure a safer and more comfortable built environment.History of engineering and technologybicssc3D reconstructionartificial neural networksatmosphereautoencoderblade tip timingbridge damage detectionBrillouin scatteringcastigliano's theoremcentrifugal compressorcolorimetric detectionconvolutional neural networkcorrosion sensorcrack detectioncrack measurementcrack openingcrackingdamage indexdeep learningdepth sensorDICdistributed fiber optic sensorsdistributed measurementsdistributed optical fiber strain sensing cabledistributed vibrationelasto-plastic behaviorenvironmental monitoringequivalent lengthfeature extractionFiber Bragg gratingFiber Bragg Grating (FBG)fiber optic gyroscopefiber optic sensorsfiber optic sensors embedded in concreteflexural cracksFusarium head blightgrowth stagehybrid processeshyperspectral imagingimage-based measurementload estimationload localizationmaterial extrusionmicrocrackingmonitoringnon-synchronous blade vibrationnuclear power plantoil and gas pipelinesoptical fiber sensorsoptical fibersPADphotometric stereorandom forestRayleigh scatteringrotating stallscourshear cracksSHMsimilarity measuresoil-structure interactionspectral indicesstrain measurementstrain sensing cable characterizationstrain sensitivity coefficientsstructural health monitoringsubway tunneltemperature and strain monitoringtestingUHPFRCultra-weak FBGvisual inspectionwaterweldable fiber optic sensorswinkler modelHistory of engineering and technologyAntunes Pauloedt1311314Varum HumbertoedtAntunes PauloothVarum HumbertoothBOOK9910557104003321Optical Sensors for Structural Health Monitoring3030233UNINA
