On the feasibility of synchronous, retransmission-based cognitive networks
This paper presents a new, joint Markov chain model for the primary and secondary traffic in a cognitive radio network to assess the feasibility of opportunistic spectrum access for different operational scenarios, validated ...
Instability and stability properties of traveling waves for the double dispersion equation
In this article we are concerned with the instability and stability properties of traveling wave solutions of the double dispersion equation View the MathML source for View the MathML source, View the MathML source. The ...
Derivation of generalized Camassa-Holm equations from Boussinesq-type equations
(Informa Group, 2016)
In this paper we derive generalized forms of the Camassa-Holm (CH) equation from a Boussinesq-type equation using a two-parameter asymptotic expansion based on two small parameters characterizing nonlinear and dispersive ...
Pricing decisions in a strategic single retailer/dual suppliers setting under order size constraints
(Informa Group, 2016)
In this paper, we study a duopolistic market of suppliers competing for the business of a retailer. The retailer sets the order cycle and quantities from each supplier to minimize its annual costs. Different from other ...
A stochastic optimization model for designing last Mile relief networks
In this study, we introduce a distribution network design problem that determines the locations and capacities of the relief distribution points in the last mile network, while considering demand- and network-related ...
Stage: stereotypical trust assessment through graph extraction
Bootstrapping trust assessment where there is little or no evidence regarding a subject is a significant challenge for existing trust and reputation systems. When direct or indirect evidence is absent, existing approaches ...
Model-based software product line testing by coupling feature Mmodels with hierarchical Markov chain usage models
Model-based testing automates test case generation based on usage models of a system. In this paper, we introduce an approach for systematic reuse of these models for testing a large family of products. In our approach, ...
Analysis of asynchronous cognitive radio system with imperfect sensing and bursty primary user traffic
(Springer Science+Business Media, 2016-03)
This paper presents a theoretical analysis of the spectrum utilization levels in a cognitive radio system. We assume that the traffic of the primary network is bursty and asynchronous with the secondary network, which ...
Sparse channel estimation and equalization for OFDM-based underwater cooperative systems with amplify-and-forward relaying
This paper is concerned with a challenging problem of channel estimation and equalization for amplifyand- forward cooperative relay based orthogonal frequency division multiplexing (OFDM) systems in sparse underwater ...
