A communication theoretical analysis of multiple-access channel capacity in magneto-inductive wireless networks
(IEEE, 2017-06)
Magneto-inductive (MI) wireless communications is an emerging subject with a rich set of applications, including local area networks for the Internet-of-Things, wireless body area networks, in-body and on-chip communications, ...
A mathematical model for customer lifetime value based offer management
(Springer, 2018)
Customers with prepaid lines possess higher attrition risk compared to postpaid customers, since prepaid customers do not sign long-term obligatory contracts and may churn anytime. For this reason, mobile operators have ...
Delivery phase in cache-based wireless networks with modified LT codes
(Springer Nature, 2020-10)
Caching has emerged as an efficient technique to reduce delivery latency and network congestion. The focus of this paper is on content delivery in the caching-based wireless systems. In view of the fact that in such systems, ...
An effective formulation of the multi-criteria test suite minimization problem
(Elsevier, 2020-10)
Test suite minimization problem has been mainly addressed by employing heuristic techniques or integer linear programming focusing on a specific criterion or bi-criteria. These approaches fall short to compute optimal ...
Space–time trellis-coded ofdm systems in frequency-selective mobile fading channels
(IEEE, 2017-06)
Space-time trellis code (STTC) techniques provide both coding gain and diversity gain to orthogonal frequency-division multiplexing (OFDM) systems without reducing bandwidth efficiency. However, factors such as residual ...
Risk-driven model-based testing of washing machine software: an industrial case study
(IEEE, 2018-07-16)
We previously introduced an approach for risk-driven model-based testing. In that approach, test models are represented in the form of Markov chains and test case generation is steered by state transition probabilities. ...
Service center staffing with cross‐trained agents and heterogeneous customers
(Wiley, 2019-04)
We model a real-world service center with cross-trained agents serving customer requests that are heterogeneous with respect to complexity and priority levels: High priority requests preempt low priority requests and ...
Asymptotic optimality of finite model approximations for partially observed markov decision processes with discounted cost
(IEEE, 2020-01)
We consider finite model approximations of discrete-time partially observed Markov decision processes (POMDPs) under the discounted cost criterion. After converting the original partially observed stochastic control problem ...
Experimental and numerical investigation of inlet temperature effect on convective heat transfer of γ-Al2O3/Water nanofluid flows in microtubes
(Taylor & Francis, 2019-06-15)
Nanofluids are the combination of a base fluid with nanoparticles with sizes of 1–100 nm. In order to increase the heat transfer performance, nanoparticles with higher thermal conductivity compared to that of base fluid ...
Biocompatible MOFs for storage and separation of O2: A molecular simulation study
(American Chemical Society, 2019-02-27)
Metal organic frameworks (MOFs) are great candidates for capturing 02 due to their highly porous structures and tunable physical and chemical properties. In this study, we assessed the performance of 1525 biocompatible ...
