We show that timed branching bisimilarity as defined by Van der Zwaag [16] and Baeten and Middelburg [2] is not an equivalence relation, in case of a dense time domain. We propose ...
Schur's transforms of a polynomial are used to count its roots in the unit disk. These are generalized them by introducing the sequence of symmetric sub-resultants of two pol...
We use some recent techniques from process algebra to draw several conclusions about the well studied class of ping-pong protocols introduced by Dolev and Yao. In particular we sho...
Aspect-oriented concepts are currently introduced in early stages of software development to achieve better separation of concerns. However, at the architecture level, there exists...
We describe Nonnegative Double Singular Value Decomposition (NNDSVD), a new method designed to enhance the initialization stage of nonnegative matrix factorization (NMF). NNDSVD c...
