In this paper, we restudy the non-convex data factorization problems (regularized or not, unsupervised or supervised), where the optimization is confined in the nonnegative orthan...
Bounded model checking--as well as symbolic equivalence checking--are highly successful techniques in the hardware domain. Recently, bit-vector bounded model checkers like CBMC ha...
An ambient is a named cluster of processes and subambients, which moves as a group. We describe type systems able to guarantee that certain ambients will remain immobile, and that ...
In distributed computing systems, it is unwise to move data to the point of program code, but instead process data at the point of storage. This concept is even more appropriate t...
Usually software is maintained by people different from those who developed it. In this context the maintenance activities are dominated by the comprehension effort. The study of ...
