On the Error Performance of Non-orthogonal Multiple Access Systems
( IEEE Computer Society , 2020 , Conference Paper)Unlike orthogonal multiple access schemes, non-orthogonal (NOMA) ones have arisen as an appealing solution to meet the requirements of the upcoming era of massive connectivity. In NOMA schemes, users are allowed to ... -
On the estimation of reliabilty function in a Weibull lifetime distribution
( Taylor & Francis , 2008 , Article)The estimation of the reliability function of the Weibull lifetime model is considered in the presence of uncertain prior information (not in the form of prior distribution) on the parameter of interest. This information ... -
On the evaluation of flue gases capturing capacity of porous organic materials
( Avestia Publishing , 2016 , Conference Paper)Integrated Gasification Combined Cycle (IGCC) has been emerged as an efficient alternative to post and oxy-combustion systems for power generation with controllable CO2 capture and separation. However, this system operates ... -
On the evaluation of tweet timeline generation task
( Springer Verlag , 2016 , Conference Paper)Tweet Timeline Generation (TTG) task aims to generate a timeline of relevant but novel tweets that summarizes the development of a given topic. A typical TTG system first retrieves tweets then detects novel tweets among ... -

On The Formation of Intermediate & Deep Water Masses in The Eastern Mediterranean
( Qatar University , 2000 , Article)In the eastern Mediterranean, three main water masses are classified: Modified Atlantic Water of Atlantic origin, Levantine Intermediate Water (LIW), formed in winter during storm events and Eastern Mediterranean Deep Water ... -
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 ... -
