Discrete 2D Fourier Transform In Polar Coordinates
The discrete Fourier transform in Cartesian coordinates has proved to be invaluable in many disciplines. However, less theory has been developed for functions that are best described in polar coordinates. In this paper, a ...
Modelling Thermal Conductivity Of Porous Thermal Barrier Coatings For High-Temperature Aero Engines Using Five Phase Model
Thermal Barrier Coatings (TBC) are used to shield hot sections of gas turbine engines, helping to prevent the melting of metallic surfaces. This paper proposes a Five-phase model to calculate the effective thermal conductivity ...
Effect Of Photoacoustic Radar Chirp Parameters On Profilometric Information
Continuous wave photoacoustics has been under investigation for more than a decade. Matched-filtering and pulse compression techniques, which use a chirp waveform as input light source, have been implemented into this ...
