This was a M.Sc. project of Efi Ezri.

Calibration unit

From Wikipedia:

“An anemometer is a device for measuring the velocity or the pressure of the wind, and is one instrument used in a weather station. The term is derived from the Greek word, anemos, meaning wind.” Read more about hot-wire anemometers on eFunda web site.

LUT:

LUT is a shortcut of the lookup-table (In computer science, a lookup table is a data structure, usually an array or associative array, used to replace a runtime computation with a simpler lookup operation. The speed gain can be significant, since retrieving a value from memory is often faster than undergoing an expensive computation. Wikipedia)

Details

The algorithm and the software package are developed jointly by a group of students and researchers at the Faculty of Engineering, Tel Aviv University http://www.eng.tau.ac.il

  • it’s an open source under BSD license
  • it’s written currently in Matlab (works fine under Windows XP, Matlab R2006x)
  • it makes use of the following open-source Matlab packages from the Matlab Central:
    • kdtree by Steven Michael, MIT
    • kNearestNeighbors by Ani
    • inpaint_nans by John D’Errico
  • it’s developed using a generous help of Lavoie P. from Queen’s University, Canada, providing us with his Labview subroutines (not actually used, but very helpful). Read, e.g. his publication: PDF or look at Scholar
  • Ideas are taken mostly from the literature (easiest way is to google for “multi hot wire calibration”, e.g. >>>
    • Lavoie P. et al, Exp. Fluids, etc.
    • van Daijk et al. Exp. Fluids, 2004
