We introduce bi-capacities as a natural generalization of capacities (or fuzzy measures) through the identity of Choquet integral of binary alternatives with fuzzy measures. We examine the underlying structure and derive the Möbius transform of bi-capacities. Next, the Choquet and Sugeno integrals w.r.t bicapacities are introduced. It is shown that symmetric and asymmetric integrals are recover...

Critical infrastructures are interconnected on multiple levels, and due to their size models with acceptable computational complexity and adequate modeling capacities must be developed. This paper presents the skeleton of a graph based model and sketches its capabilities.

We take a capacity view of a number of different space-time coding (STC) schemes. While the Shannon capacity of multipleinput multiple-output (MIMO) channels has been known for a number of years now, the attainment of these capacities remains a challenging issue in many cases. The introduction of space-time coding schemes in the last 2–3 years has, however, begun paving the way towards the atta...

The first result is on the separability of the unicast capacity of stationary multi-channel multi-radio wireless networks, i.e., whether the capacity of such a network is equal to the sum of the capacities of the corresponding single-channel singleradio wireless networks. For both the Arbitrary Network model and the Random Network model, given a channel assignment, the separability property doe...

Modern wireless networks are faced with an increasing demand for higher data rates, better quality of service, and higher overall network capacities. In order to comply to these demands various limits, like the limited availability of the frequency spectrum and a complex space-time varying wireless environment must be overcome. Transmission schemes based on Multiple Input Multiple Output (MIMO)...
