Flexible architecture of relay-based wireless network for network lifetime extension with hop-count constraint
(Informa Group, 2011)In relay-based wireless networks, messages need to be forwarded via intermediate relay mobile terminals (MTs). However, because of various transmission distances and unbalanced traffic load, some relay MTs may tend to drain ... -
RANSAC-based training data selection on spectral features for emotion recognition from spontaneous speech
(Springer International Publishing, 2011)Training datasets containing spontaneous emotional speech are often imperfect due the ambiguities and difficulties of labeling such data by human observers. In this paper, we present a Random Sampling Consensus (RANSAC) ... -
Minimum power architecture of relay-based network with bandwidth and hop-count constraints
(Trans Tech Publications, 2011)Energy bills are on the rise and with the recent attention to saving the global environment. Saving energy (minimizing energy consumption) is becoming a standard issue for all industrial and commercial applications. Moreover, ... -
NEEL: The nested complex event language for real-time event analytics
(Springer International Publishing, 2011)Complex event processing (CEP) over event streams has become increasingly important for real-time applications ranging from health care, supply chain management to business intelligence. These monitoring applications submit ... -
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 ... -
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 ... -
Relay selection in dual-hop vehicular networks
(IEEE, 2011-02)In this letter, we investigate cooperative diversity with relay selection over cascaded Rayleigh fading channels. In particular, we analyze the performance of a relay selection scheme for cooperative vehicular networks ... -
Lane-exchange mechanisms for truckload carrier collaboration
(Informs, 2011-02)Because of historically high fuel prices, the trucking industry's operating expenses are higher than ever and thus profit margins are lower than ever. To cut costs, the trucking industry is searching for and exploring new ... -
Flexible aircraft fleeting and routing at TunisAir
(Palgrave Macmillan, 2011-02)This paper addresses a Flexible Aircraft Fleeting and Routing Problem, which is motivated by the Tunisian national carrier TunisAir. A solution to this problem specifies the departure time of each flight, the subset of ... -
Moment generating function-based performance evaluation of amplify-andforward relaying in N∗Nakagami fading channels
(IEEE, 2011-02-11)In this study, the authors investigate the error rate performance of amplify-and-forward relaying over N∗Nakagami fading channels. This is a recently introduced channel model that involves the product of N Nakagami-m-distributed ... -
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 ... -
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 ... -
Relaxations and exact solution of the variable sized bin packing problem
(Springer Science+Business Media, 2011-03)We address a generalization of the classical one-dimensional bin packing problem with unequal bin sizes and costs. We investigate lower bounds for this problem as well as exact algorithms. The main contribution of this ... -
Radiative transfer configuration factor catalog: a listing of relations for common geometries
(Elsevier, 2011-03)An on-line compilation of radiation configuration factors for over 300 common geometries is provided as a supplementary material from the JQSRT web site at doi:10.1016/j.jqsrt.2010.10.002. The factors are gathered from ... -
Effect of slurry aging on stability and performance of chemical mechanical planarization process
(Elsevier, 2011-03)Chemical mechanical planarization (CMP) is known to be one of the most challenging processes in microelectronics manufacturing due to the number of variables involved in the design of the process. In particular, the slurries ... -
Effect of commercial purity levels on the mechanical properties of ultrafine-grained titanium
(Elsevier, 2011-03-15)Two grades of commercial purity (CP) titanium (grades 2 and 4) were processed using equal-channel angular extrusion (ECAE) at 300 ◦C and 450 ◦C, respectively. The processing temperatures were the minimum temperatures at ... -
A Monte Carlo simulation for phonon transport within silicon structures at nanoscales with heat generation
(Elsevier, 2011-04)Nanoscale phonon transport within silicon structures subjected to internal heat generation was explored. A Monte Carlo simulation was used. The simulation procedures differed from the current existing methods in which ... -
Estimating quantitative features of nanoparticles using multiple derivatives of scattering profiles
