2004-8-28  Yee et al. [6] in 1993 discussed a curve-fit method in which all the desorption data are fitted to a solution of the diffusion equation. This contrasts with the Bureau of Mines and other methods that use only selected early-time measurements to estimate lost gas. This curve-fit method has been referred to as the “Amoco Method” [7, 11].

A survey of landmine detection using hyperspectral

2017-2-1  The linear unmixing method has a higher Probability of detection in the case of subpixel sized mines; but has also a higher false alarm rate. Other tests led to study the possibility of detecting buried landmines using a VNIR imager. It was noticed that buried mines could not be detected by calculating the shift of the red edge of vegetative ...

Java MineSweeper: Calculating the amount of mines

2014-10-23  Let's say the field has a total of 64 cells, and the user chose an "Advanced" difficulty. Let's say that 50% of the cells will be filled with mines, so there would be a total of 32 mines (field total magnitude / 100 * 50). The problem I'm having is that the returning value is always 0. This is the method
