Webb’s image is approximately the size of a grain of sand held at arm’s length, a tiny sliver of the vast universe. The combined mass of this galaxy cluster acts as a gravitational lens, magnifying more distant galaxies, including some seen when the universe was less than a billion year...

In the chalk of the Ekofisk formation in the Chalk Group of the North Sea, substantial depth-related variations in porosity are observed. With the aim of obtaining a textural interpretation of these porosity data, we have developed a method to assess the grain size distribution of the chalk fr...
The first algorithm characterized each object in a binary image of a grain sample as either an isolated kernel or a group of occluding kernels by determining the degree of overlap between each object in the input image and its inertial equivalent ellipse. If the degree of overlap was ...
