Application for searching for defects in plates (Ellipse method and Time-reversal)

The project has many dependences with math classes library

1. Install R > 3.6 (u can use this site)

2. Set Rscript.exe as default application to running .r files

3. Run this file (as administator) to install necessary packages

1. Record "clean" signal (just signal from default material)

2. Record signal after creating defect

3. Create the difference between these signals

4. Create Furier transform of this difference

Furier transform of signal is the important parameter of using fit. Firstly, it creates a tensor of u(x, variety) function values, after that it creates a tensor of u(x, t) function values and prepare this tensor according to selected metric. After all u can see the surface to determine the location of defect.

There are several important hyper-parameters for determining defect's location: sensors' location and variety, time and space nets (the thicker net is better, but takes more time for calculating).

There is another interesting fit with same parameters.

Use RMdator.exe to removing most large data files.
