To ensure the correctness of network analysis methods, the network (as the input) has to be a sufficiently accurate representation of the underlying data. However, when representing sequential data from complex systems, such as global shipping traffic or Web clickstream traffic as networks, conventional network representations that implicitly assume the Markov property (first-order dependency) ...

Controller Area Network (CAN) is a real-time network that was initially conceived for automotive applications, but which is now becoming very popular as a fieldbus for automated factory environments because of its appealing features and low implementation costs. Controller Area Networks (CANs) are being used more and more today to support communications in real-time systems. However, under heav...

ground skidding on skid trails affects the physical properties of soil. the objective of this study was to evaluate changes in soil physical properties on skid trails formed due to traffic of metal-tracked skidders with regard to soil bulk density, total porosity, water content and penetration resistance. the studies were implemented on two levels of slope – 20% (sc2) – and three levels of traf...

Several years of NASA research have produced the air traffic management operational concept of ‘Autonomous Flight Management’ with high potential for operational feasibility, significant system and user benefits, and safety. Among the chief potential benefits are demand-adaptive or ‘scalable’ capacity, user flexibility and autonomy that may finally enable truly successful business strategies, a...

The notion of extensionality of a fuzzy relation w.r.t. a fuzzy equivalence was first introduced by Höhle and Blanchard. Bělohlávek introduced a similar definition of compatibility of a fuzzy relation w.r.t. a fuzzy equality. In [14] we generalized this notion to left compatibility, right compatibility and compatibility of arbitrary fuzzy relations and we characterized them in terms of left and...

Bi-Hamiltonian structures are of great importance in the theory of integrable Hamiltonian systems. The notion of compatibility of symplectic structures is a key aspect of bi-Hamiltonian systems. Because of this, a few different notions of compatibility have been introduced. In this paper we show that, under some additional assumptions, compatibility in the sense of Magri implies a notion of com...
