The use of diversity in the reception of mobile radio signals is well known and is implemented in most wireless systems of today. Several authors have studied polarization diversity [1{4]. However, no study has to our knowledge analyzed the e ect of the actual base station antenna characteristics on the diversity performance. In this paper we study the envelope correlation and signal strength a...

A state-based technique for the representation and recognition of gesture is presented. We de ne a gesture to be a sequence of states in a measurement or con guration space. For a given gesture, these states are used to capture both the reapeatability and variability evidenced in a training set of example trajectories. Using techniques for computing a prototype trajectory of an ensemble of traj...

A random graph model with prescribed degree distribution and degree dependent edge weights is introduced. Each vertex is independently equipped with a random number of half-edges and each half-edge is assigned an integer valued weight according to a distribution that is allowed to depend on the degree of its vertex. Half-edges with the same weight are then paired randomly to create edges. An ex...

We propose a knowledge-based approach to the task of determining the topology of mul-tilayer perceptrons (MLPs). The idea consists in integrating well-founded and empirically proven connguration techniques into a knowledge-based system. A preliminary study showed that the use of these techniques depends primarily on the amount of prior domain knowledge available: connguration techniques can be ...

As switch-based networks have become promising network platforms to build workstation clusters for high performance computing, many types of (expensive) switches have been developed to support high-speed communication. However, their communication performance heavily depends on the connguration of switches and the deadlock problem caused by wormhole switching is another crucial factor in eecien...

Selective impairment in recognition of faces (prosopagnosia) has been advanced as an argument for a brain module dedicated to face processing and focusing on the speci®c con®gural properties of faces. Loss of the inversion e€ect supposedly strengthened the argument ([10]: de Gelder B, Bachoud-Levi AC, Degos JD. Inversion superiority in visual agnosia may be common to a variety of orientation po...

Many strategies for improving performance of distributed programs can be described abstractly in terms of an application's overall connguration. But previously those techniques would need to be implemented manually, and the resulting programs, though yielding good performance, are more expensive to build and much less easy to reuse. This paper describes research towards an automatic system for ...

The Price of Anarchy (PoA) is a measure that compares the ratio between the maximum and minimum of a cost function evaluated at any Nash equilibrium of a game. There have been many results that bound the highest PoA for certain classes of games, but little has been done to explore the distribution of the PoA over a set of games. This project proposes a method to empirically evaluate this distri...

This paper studies the formal underpinnings of the product connguration problem. A rule-based language is proposed for expressing typical forms of knowledge interactions in connguration models, i.e. choices, dependencies between choices, optionality and defaults. The language is equipped with a declarative semantics that provides formal deenitions for the main concepts in product connguration, ...
