Optimal bit and power loading for amplify-and-forward cooperative OFDM systems
(IEEE, 2011-03)
In this paper, we investigate bit and power allocation strategies for an orthogonal frequency division multiplexing (OFDM) cooperative network over frequency-selective fading channels. We assume amplify-and-forward relaying ...
Multi-hop coherent free-space optical communications over atmospheric turbulence channels
(IEEE, 2011)
In this paper, we investigate multi-hop relaying as an efficient fading mitigation tool for coherent free-space optical (FSO) systems over atmospheric turbulence channels. We consider an FSO relaying system with ...
Peer-to-peer multipoint video conferencing with layered video
(Elsevier, 2011-01)
A peer-to-peer (P2P) architecture for multipoint video conferencing using layered video coding at the end hosts is proposed. The system primarily targets end points with low bandwidth network connections and enables them ...
Solving two-stage hybrid flow shop using climbing depth-bounded discrepancy search
(Elsevier, 2011-03)
This paper investigates how to adapt a discrepancy-based search method to solve two-stage hybrid flowshop scheduling problems in which each stage consists of several identical machines operating in parallel. The objective ...
Defining architectural viewpoints for quality concerns
(Springer Science+Business Media, 2011)
A common practice in software architecture design is to apply architectural views to model the design decisions for the various stakeholder concerns. When dealing with quality concerns, however, it is more difficult to ...
RANSAC-based training data selection for speaker state recognition
(The International Speech Communications Association, 2011)
We present a Random Sampling Consensus (RANSAC) based training approach for the problem of speaker state recognition from spontaneous speech. Our system is trained and tested with the INTERSPEECH 2011 Speaker State ...
Smart job scheduling for high-performance cloud computing services
(Civil-comp, 2011-01)
In this paper, we describe the challenges faced and lessons learned while establishing a large-scale high performance cloud computing service that enables online mechanical structural analysis and many other scientific ...
High-rate distributed space-time-frequency coding for wireless cooperative networks
(IEEE, 2011-02)
In this paper, we propose high-rate distributed space-time-frequency codes (DSTFCs) to exploit maximum achievable diversity gains over frequency-selective fading channels. The proposed designs achieve full-rate for any ...
Testing for convergence in bank efficiency: a cross-country analysis
(Taylor & Francis, 2011)
This paper empirically investigates a possible convergence among the operational efficiency of financial institutions across countries. We explore (i) the relative performance of banking industries in two samples (European ...
Isovector axial-vector form factors of octet baryons in QCD
(American Physical Society, 2011-06-01)
We compute the diagonal isovector axial-vector as well as induced pseudoscalar form factors of nucleon, Σ, and ≡ baryons by employing the light-cone QCD sum rules to leading order in QCD and including distribution amplitudes ...
