Support Vector Clustering for Brain Activation Detection
In this paper, we propose a new approach to detect activated time series in functional MRI using support vector clustering (SVC). We extract Fourier coefficients as the features of...

A Coalition Formation Game in Partition Form for Peer-to-Peer File Sharing Networks
In current peer-to-peer file sharing networks, a large number of peers with heterogeneous connections simultaneously seek to download resources, e.g., files or file fragments, from...

Closed-Form Expressions for the Outage and Error Probabilities of Decode-and-Forward Relaying in Dissimilar Rayleigh Fading Chan
—User cooperation protocols, where mobile stations relay signals to the final destination, have been proposed for wireless networks. A general mathematical probability model is ...

Quadratic forms on graphs
We introduce a new graph parameter, called the Grothendieck constant of a graph G = (V, E), which is defined as the least constant K such that for every A : E R, sup f:V S|V |-1 ...

Robust brain activation detection in functional MRI
Functional Magnetic Resonance Imaging (MRI) is today one of the most important non-invasive tools to study the brain from a functional point of view. The blood-oxygenation-level-d...
