Particle image velocimetry (PIV) is a non-intrusive optical flow measurement technique used to study fluid flow patterns and velocities. PIV has found widespread applications in various fields of science and engineering, including aerodynamics, combustion, oceanography, and biofluids. The development of PIV can be traced back to the early 20th ...
FIPS 201 ( Federal Information Processing Standard Publication 201) is a United States federal government standard that specifies Personal Identity Verification ( PIV) requirements for Federal employees and contractors. In response to HSPD-12, the NIST Computer Security Division initiated a new program for improving the identification and ...
An electronic data interchange personal identifier, or EDIPI, is a number assigned to a record in the United States Department of Defense's Defense Enrollment and Eligibility Reporting System (DEERS) database. A record in the DEERS database is a person plus personnel category (e.g. contractor, reservist, civilian, active duty, etc.).
Lightweight Portable Security (LPS) or Trusted End Node Security (TENS) was a Linux LiveCD (or LiveUSB) distribution. The application Encryption Wizard, originally bundled with TENS is still actively maintained. LPS and its successor TENS was developed and publicly distributed by the United States Department of Defense ’s Air Force Research ...
The Stokes number is defined as the ratio of the characteristic time of a particle (or droplet) to a characteristic time of the flow or of an obstacle, or. where is the relaxation time of the particle (the time constant in the exponential decay of the particle velocity due to drag), is the fluid velocity of the flow well away from the obstacle ...
ISO / IEC 7810 sizes. Most banking cards and ID cards. Size may also be referred to as CR-80 or TD1. Older-style ID cards. Visas. All card sizes have a thickness of 0.68 millimetres (0.027 in) minimum and 0.84 millimetres (0.033 in) maximum (i.e. 760 ± 80 μm ). The standard defines both metric and imperial measurements, noting that: [4]
the three-dimensional particle tracking velocimetry (3-D PTV) is a distinctive experimental technique originally developed to study fully turbulent flows. It is now being used widely in various disciplines, ranging from structural mechanics research to medicine and industrial environments. It is based on a multiple camera-system in a ...
Pivmecillinam ( INN ), or amdinocillin pivoxil ( USAN ), sold under the brand name Selexid and Pivya among others, is an orally active prodrug of mecillinam, an extended-spectrum penicillin antibiotic. Pivmecillinam is the pivaloyloxymethyl ester of mecillinam. The most common side effects include nausea and diarrhea. [2]
