4D-PTV Measurements of an impinged jet with a dynamic 3D-PTV
Journal of Visualization, 20054D-PTV system was constructed. The measurement system consists of three high-speed high-definition cameras (1k × 1k, 2000 fps), Nd-Yag laser (2000 Hz) and a host computer. The GA-3D-PTV algorithm was used for completing the measurement system. The 4D-PTV is capable of probing the spatial distribution of velocity vectors of the flow field overcoming the

Particle Tracking Velocimetry (PTV) is one of the evolving techniques which can cover the increasing need for measurements in a Lagrangian frame. Here some recent developments and the validation of the tracking scheme on the Kinematic Simulation Inertial Model (KSIM) test flow field is presented.

Development of interpolation-free PTV
Journal of Mechanical Science and Technology, 2021A new particle tracking velocimetry (PTV) algorithm, which has no interpolation process requirement, has been constructed. An affine transformation and a hybrid fitness function were used to obtain final vector fields. A match probability method (MPM)-based PTV algorithm was used to save calculation convergences.

Development of a tomographic PTV
Journal of Mechanical Science and Technology, 2012A new tomographic PTV (Tomo-PTV) was proposed, and then its performance was compared with that of tomographic PIV (Tomo-PIV). To construct the new tomographic PTV for calculation of vector fields, an affine transformation was introduced. The vectors obtained by match probability method were used as the initial data for the final vectors.

Emergency percutaneous transtracheal ventilation (PTV)
Journal of the American College of Emergency Physicians, 1979Ventilation through a percutaneous needle catheter inserted into the trachea has been advocated for resuscitation in acute upper airway obstruction. However, the customized, prefabricated equipment proposed by others for that use is not always available. We describe a device for percutaneous transtracheal ventilation (PTV) that can be rapidly assembled

Equivalences and optimal designs of PTV systems
ICASSP-88., International Conference on Acoustics, Speech, and Signal Processing, 2003Some equivalences or transformations between a number of periodically time-varying (PTV) digital filters are developed. The transformation between the commutator and modulator analysis structures is presented. The transformation allows the problem specification and design in either or both domains.
