Exempel på hur du använder PIV i en mening
- Typical PIV apparatus consists of a camera (normally a digital camera with a charge-coupled device (CCD) chip in modern systems), a strobe or laser with an optical arrangement to limit the physical region illuminated (normally a cylindrical lens to convert a light beam to a line), a synchronizer to act as an external trigger for control of the camera and laser, the seeding particles and the fluid under investigation.
- Velocimetry was also expanded to 3D regional measurements blood flow and tissue motion with a new technique – computed tomographic x-ray velocimetry – which uses information contained within the PIV cross-correlation to extract 3D measurements from 2D image sequences.
- The Government Smart Card Interagency Advisory Board has indicated that to comply with FIPS 201 PIV II, US government agencies should use smart card technology.
- In experimental fluid dynamics, the Stokes number is a measure of flow tracer fidelity in particle image velocimetry (PIV) experiments where very small particles are entrained in turbulent flows and optically observed to determine the speed and direction of fluid movement (also known as the velocity field of the fluid).
- MTV techniques have proven to allow measurements of velocities in inhospitable environments, like jet engines, flames, high-pressure vessels, where it is difficult for techniques like Pitot, hot-wire velocimetry and PIV to work.
- A simple voltage regulator may be made with a series resistor to drop voltage followed by a shunt zener diode whose Peak Inverse Voltage (PIV) sets the maximum output voltage; if voltage rises, the diode shunts away current to maintain regulation.
- As the name suggests, individual particles are tracked, so this technique is a Lagrangian approach, in contrast to particle image velocimetry (PIV), which is an Eulerian method that measures the velocity of the fluid as it passes the observation point, that is fixed in space.
- Plena Ilustrita Vortaro de Esperanto (PIV; Complete Illustrated Dictionary of Esperanto) is a monolingual dictionary of the language Esperanto.
- The Miro line of small, lightweight cameras is used for mobile applications or situations where size and weight might be an issue in applications such as assembly line analysis, drop testing, particle image velocimetry (PIV), animal studies, bio-mechanical studies and automotive testing.
- Featured parties: 4 Tha Luv, Ardy Pardy, Black Book Records, Cyclops Recordings, Desert Hearts, Hellbent Records, High Power, House of Wax, PIV Records, Young Art Records.
- The normalized cross-correlation (NCC) is used when one cannot assure the optical flow conservation; it happens in case of change of lighting or if particles disappear from the scene can occur in particle images velocimetry (PIV).
- Under Ehrensvärd's guidance, Yubico is the innovator behind driverless one-time password (OTP) authentication, PIV smart cards with touch-to-sign, and Hardware Security Modules that sit inside standard USB-ports.
- Other viral infections, such as respiratory syncytial virus (RSV), metapneumovirus (hMPV), rhinovirus, parainfluenza (PIV), and human coronavirus in the neonatal period are associated with recurrent wheezing in later childhood.
- Joseph Katz is an Israel-born American fluid dynamicist, known for his work on experimental fluid mechanics, cavitation phenomena and multiphase flow, turbulence, turbomachinery flows and oceanography flows, flow-induced vibrations and noise, and development of optical flow diagnostics techniques, including Particle Image Velocimetry (PIV) and Holographic Particle Image Velocimetry (HPIV).
- During the wind tunnel experiments, the researchers also took detailed Particle Imaging Velocimetry (PIV) measurements of the airflow traveling downstream of the projectile in order to fine-tune the actuators.
