Distributed Multi-Objective Resource Optimization for Mobile-Health Systems
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)Mobile-health (m-health) systems leverage wireless and mobile communication technologies to promote new ways to acquire, process, transport, and secure the raw and processed medical data. M-health systems provide the ... -
Distributed permutation flowshop scheduling problem with total completion time objective
( Springer , 2021 , Article)This paper considers the distributed permutation flowshop scheduling problem (DPFSP) which is an extension of permutation flowshop scheduling problem (PFSP). In DPFSP, there are multiple parallel factories instead of one ... -
Distributed power allocation for multi-flow carrier aggregation in heterogeneous cognitive cellular networks
( Institute of Electrical and Electronics Engineers Inc. , 2018 , Article)In this paper, we study distributed power allocation for multiflow carrier aggregation in cognitive cellular networks. Our approach differs from the conventional water filling (WF) algorithm since we deal with heterogeneous ... -
Distributed power control for carrier aggregation in cognitive heterogeneous 5G cellular networks
( Springer Verlag , 2015 , Conference Paper)In this paper, we study the distributed optimal power allocation for the carrier aggregation in next generation (5G) cognitive radio networks. The presented study relies on the power control and carrier aggregation principles ... -
Distributed reconfigurable control strategies for switching topology networked multi-agent systems
( ISA - Instrumentation, Systems, and Automation Society , 2017 , Article)In this paper, distributed control reconfiguration strategies for directed switching topology networked multi-agent systems are developed and investigated. The proposed control strategies are invoked when the agents are ... -
Distributed resource allocation in cloud-based wireless multimedia social networks
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Article)With the rapid penetration of mobile devices, more users prefer to watch multimedia live-streaming via their mobile terminals. Quality of service provision is normally a critical challenge in such multimedia sharing ... -
Distributed secondary controller to ensure proportional sharing of reactive power in AC microgrid
( Elsevier , 2022 , Article)In an ac microgrid, reactive power sharing accuracy is affected due to unequal values of interconnecting cable impedances. To resolve this issue, secondary controllers are used to compensate the effect of cable impedances. ... -
Distributed simultaneous fault detection and leader-following consensus control for multi-agent systems
( ISA - Instrumentation, Systems, and Automation Society , 2019 , Article)In this paper, the problem of distributed simultaneous fault detection and leader-following consensus control (SFDLCC) in a multi-agent network is investigated. In the proposed method, instead of designing two separate ... -
Distributed spectrum sensing of correlated observations in cognitive radio networks
(2013 , Conference Paper)In this paper, Collaborative Spectrum Sensing (CSS) as one of the most efficient sensing approaches in Cognitive Radio Networks (CRNs) is investigated when the Secondary Users (SUs) observations are assumed to be correlated. ... -
Distributed state estimation, fault detection and isolation filter design for heterogeneous multi-agent linear parameter-varying systems
( Institution of Engineering and Technology , 2017 , Article)In this study, the authors present a new approach for the design of distributed state estimation and fault detection and isolation (FDI) filters for a class of linear parameter-varying multi-agent systems, where the ... -
Distributed turbo coding using log-likelihood thresholding for cooperative communications
( IEEE , 2009 , Article)In cooperative communications, error propagation at relays reduces the diversity order of the system. To combat that effect, we present a novel technique to control error propagation at the relays, which is presented in ... -
Distribution and diversity of aquatic insects in different water bodies of Qatar
( Instituto Internacional de Ecologia , 2024 , Article)Aquatic insect fauna remains an important tool for bio indication of environmental disturbance, while maintaining a healthy aquatic system. The purpose of the study was to document and to identify the diversity and ... -
Distribution and Diversity of Benthic Marine Macroalgae in Islands Around Qatar
( Qatar University Press , 2020 , Poster)Extending into the Arabian Gulf, Qatar is surrounded by a number of islands mostly scattered by the eastern coastline. With the unique physical characteristics of the Gulf which is a highly saline sea with high seawater ... -
Distribution and environmental geochemical indices of mercury in tar contaminated beaches along the coast of Qatar
( Elsevier , 2022 , Article)The current study aimed to gauge total mercury (THg) concentration and the environmental geochemical indices in tarmat contaminated sediments and test their presence in targeted coastal species. Layers of hard asphalt-like ... -
