Testing model transformations requires input models which are graphs of inter-connected objects that must conform to a meta-model and meta-constraints from heterogeneous sources su...
Using internet for media-based real-time collaboration has become widespread activity. In this paper, we present a framework called CoUniverse, designed for building realtime user...
New Internet services and technologies call for higher packet switching capacities in the core network. Thus, a performance bottleneck arises at the backbone routers, as forwarding...
— Many deterministic algorithms in the context of constrained optimization require the first-order derivatives, or the gradient vectors, of the objective and constraint function...

In this paper, we develop a beamforming algorithm for multiuser MIMO-relaying wireless systems. We consider a relaying scenario with multiple sources transmitting to one or more d...
