The size of a data structure (i.e., the number of elements in it) is a widely used property. However, for concurrent programs, obtaining a correct size efficiently is non-trivial, and in fact, there exists no mechanism for that in the literature. We start by reviewing desired properties for concurrent data structures in general,…

The fundamental challenge of applying computer vision algorithms in the marine environment is how dynamic it is: objects like fishes are constantly moving, seaweed and soft coral change their shapes with water current, light becomes everchanging and also attenuates as we go deeper. Depending on the season, location, and even…
