cumulus convection, as a meso-scale phenomenon, results in the release of latent heat and vertical drift of energy that by part could affect the large scale field of energy, humidity, and momentum of the atmosphere. since the current numerical models are unable to resolve the singular cumulus convective clouds that are important from a meteorological point of view, it is used to apply some sort...

Content availability has become increasingly important for the Internet delivery chain. In order to enhance availability, content distribution network (CDN) providers have invested in hybrid designs that combines resources from datacenter and edge networks. Although, to deliver videos with an outstanding availability and meet the increasing user expectations, hybrid CDNs must enforce strict QoS...

The Hamiltonian structures of several hybrid kinetic-fluid models are identified explicitly, upon considering collisionless Vlasov dynamics for the hot particles interacting with a bulk fluid. After presenting different pressure-coupling schemes for an ordinary fluid interacting with a hot gas, the paper extends the treatment to account for a fluid plasma interacting with an energetic ion speci...

Future multi-tier communication networks will require enhanced network capacity and reduced overhead. In the absence of Channel State Information (CSI) at the transmitters, Blind Interference Alignment (BIA) and Topological Interference Management (TIM) can achieve optimal Degrees of Freedom (DoF), minimizing network’s overhead. In addition, Non-Orthogonal Multiple Access (NOMA) can increase th...

We review and compare Bell-state measurement and quantum teleportation schemes using linear optics with three different types of resources, i.e., two-photon pairs, entangled coherent states and hybrid entangled states. Remarkably, perfect teleportation with linear optics is possible in principle based on a hybrid approach that combines two-photon pairs and entangled coherent states. It turns ou...

Abstract— In this article, we present hybrid multiple-input multiple-output (MIMO) transceiver schemes (HMTS) that combine transmit diversity and spatial multiplexing, thus achieving at the same time the two possible spatial gains offered by MIMO systems. For these transceivers, a modification in the interference nulling-and-cancelling algorithm used in traditional MIMO schemes is proposed. We ...

In this paper, we introduce the robust recursive GPCA algorithm that can segment a set of data points into multiple unknown linear models with different dimensions in the presence of noise and outliers. The algorithm is designed based on a robust model selection criterion for mixtures of subspaces called minimum effective dimension (MED). We apply the robust GPCA algorithm in a video segmentati...

Incorporating mobile components into a distributed system has posed new challenges to the design of distributed computation. This paper studies a fundamental problem in distributed computing, the termination detection problem, in a mobile environment. Two types of termination detection protocols already exist: the diiusion-based schemes 3, 10] and the weight-throwing schemes 6, 13, 18], that ar...

In this paper, we propose a generic hybrid oriented-transform and wavelet-based image representation for intra-band image coding. We instantiate for three popular directional transforms having similar powers of approximation but different redundancy factors. For each transform type, we design a compression scheme wherein we exploit intra-band coefficient dependencies. We show that our schemes o...

Clustering ensembles has been recently recognized as an emerging approach to provide more robust solutions to the data clustering problem. Current methods of clustering ensembles typically fall into instance-based, cluster-based, or hybrid approaches; however, most of such methods fail in discriminating among the various clusterings that participate to the ensemble. In this paper, we address th...
