On the domain of Choquet expected utility preferences with risk neutral lottery evaluation and totally monotone capacities, we demonstrate that proper scoring rules do not exist. This implies the non-existence of proper scoring rules for any larger class of preferences (CEU with convex capacities, multiple priors). We also show that if an agent whose behavior conforms to the multiple priors mod...

It has been predicted theoretically that for some environments, the capacity of wireless MIMO systems can become very low even for uncorrelated signals; this effect has been termed keyhole or pinhole. In this paper the first measurements of this effect are presented. The measurements were performed in a controlled indoor environment that was designed to create a keyhole effect. We analyze limit...

We propose a general notion of capacity defined on any finite distributive lattice, encompassing usual capacities, bi-capacities, and their immediate extensions called k-ary capacities. We define key notions such as Möbius transform, derivative, Shapley value and Choquet integral.

In this paper we consider a generalization of the classical k-center problem with capacities. Our goal is to select k centers in a graph, and assign each node to a nearby center, so that we respect the capacity constraints on centers. The objective is to minimize the maximum distance a node has to travel to get to its assigned center. This problem is NP -hard, even when centers have no capacity...

~Packet scheduling is investigated for the downlink of a multiple-input multiple-output (MIMO) cellular system. The conventional round robin scheduling (RRS) scheme does not utilize the benefits of multiuser environments, although it provides fair channel access chance to users. We propose an antenna-assisted round robin scheduling (AA-RRS) scheme to improve the conventional RRS scheme. The AA-...
