Static analysis cannot obtain the values of variables in actual program operation because it does not execute the code itself. It makes the detection of invalid arithmetic operation (IAO) in the field of static analysis difficult to achieve. This paper presents a practical model for IAO detection based on alias analysis. The model uses a triple to record information calculated in dataflow. In the...
Now the fractal dimension of Land Use Types is often calculated by using raster data as the raw data, but quite a number of spatial data is stored as vector data in fact. If these vector data are converted to images to calculate fractal dimension, perhaps some pixels with inaccurate grey value will result from the “GRID” structure of raster data and accordingly reduce the accuracy of calculation....
