On the group proportional fairness of frequency domain resource allocation in L-SC-FDMA based LTE uplink
( IEEE , 2010 , Conference Paper)Localized single carrier frequency division multiple access (L-SC-FDMA) has been selected as the uplink transmission scheme in 3GPP Long Term Evolution (LTE) due to its low Peak to Average Power Ratio (PAPR) over OFDMA in ... -
On the Higher Order Statistics of the Channel Capacity in Dispersed Spectrum Cognitive Radio Systems Over Generalized Fading Channels
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Article)This work is devoted to the study of dispersed spectrum cognitive radio (CR) systems over independent and nonidentically distributed (i.n.i.d.) generalized fading channels. More specifically, this is performed in terms of ... -
On the increasing importance of multiple criteria decision aid methods for portfolio selection
( Taylor and Francis Ltd. , 2018 , Article)In 1952, Markowitz published his famous paper on portfolio selection that transformed the field of finance. Although over 65years have passed since then, the mean-variance model remains today the predominant model in ... -
On the Investigation of Monthly River Flow Generation Complexity Using the Applicability of Machine Learning Models
( Hindawi Limited , 2021 , Article)Streamflow is associated with several sources on nonstationaries and hence developing machine learning (ML) models is always the motive to provide a reliable methodology to understand the actual mechanism of streamflow. ... -
On the joint scheduling and intra-cell interference coordination in multi-relay LTE uplink
( IEEE , 2012 , Conference Paper)The relay-assisted Long Term Evaluation (LTE) cellular system is one of the most promising technologies to enhance the throughput and coverage of the access network. Injection of relays in a cell opens many issues of ... -
On the Lp boundedness of rough parametric Marcinkiewicz functions
( Victoria University , 2007 , Article)In this paper, we study the Lp boundedness of a class of parametric Marcinkiewicz integral operators with rough kernels in L(log + L)(Sn-1). Our result in this paper solves an open problem left by the authors of ([6]). -

On the minimum ignition energy and its transition in the localised forced ignition of turbulent homogeneous mixtures
( Elsevier Inc. , 2019 , Article)The minimum energy requirements for ensuring (i) just successful ignition and (ii) successful self-sustained flame propagation without the assistance of an external energy source following a successful ignition event have ... -
On the Modeling of Reliability in Extreme Edge Computing Systems
( IEEE , 2022 , Conference Paper)Extreme edge computing (EEC) refers to the end-most part of edge computing wherein computational tasks and edge services are deployed only on extreme edge devices (EEDs). EEDs are consumer or user-owned devices that offer ... -
On the molecular properties of graphene-pyrazines conjugated Ru and Fe complexes: Computational insights
( Elsevier , 2020 , Article)Graphene and related materials can exhibit substantial molecular properties of significant importance in various landscapes of interests including catalysis. On the other hand, transition-metal-based molecular heterogeneous ... -
On the more accurate channel model and positioning based on time-of-arrival for visible light localization
( SPIE , 2017 , Article)This paper presents an improved propagation channel model for the visible light in indoor environments. We employ this model to derive an enhanced positioning algorithm using on the relation between the time-of-arrivals ... -
On the nanogate-opening pressures of copper-doped zeolitic imidazolate framework ZIF-8 for the adsorption of propane, propylene, isobutane, and n-butane
( Springer New York LLC , 2019 , Article)In this study, a zeolitic imidazolate framework-8 (ZIF-8) and its copper-doped variants (Cu-doped ZIF-8) were synthesized using a rapid microwave technique. The products were characterized by XRD, NanoSEM, FTIR, Raman ... -
On the nature of defect states in tungstate nanoflake arrays as promising photoanodes in solar fuel cells
( Royal Society of Chemistry , 2016 , Article)An electrochemical method is presented to study the nature of the defect states in sub-stoichiometric tungsten oxide nanoflake photoanodes used in water splitting. First, stoichiometric/sub-stoichiometric tungstate nanoflake ... -
On the nonexistence of degenerate phase-shift discrete solitons in a dNLS nonlocal lattice
( Elsevier B.V. , 2018 , Article)We consider a one-dimensional discrete nonlinear Schrdinger (dNLS) model featuring interactions beyond nearest neighbors. We are interested in the existence (or nonexistence) of phase-shift discrete solitons, which correspond ... -
On the nonexistence of degenerate phase-shift multibreathers in Klein–Gordon models with interactions beyond nearest neighbors
