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 ... -
Distribution And Mineralogy Of The Clay Deposits In Saudi Arabia
( Qatar University , 1993 , Article)The main goal of this paper is to characterize the mineral clay deposits in Saudi Arabia; especially their mineral composition, deposit size, geological setting and possible uses. Different published reports and papers on ... -
Distribution and ultrastructure of neurosecretory cells in the cerebral ganglion of the earthworm
( Wiley Subscription Services, Inc., A Wiley Company , 1988 , Article)Neurosecretory (Nsy) cells within the cerebral ganglion of Lumbricus terrestris were classified ultrastructurally. The Nsy cells within the subesophageal ganglion, nerve cord ganglion, and the peripheral nervous system ... -
The distribution of Blastocystis subtypes in isolates from Qatar
( BioMed Central Ltd. , 2015 , Article)Background: Blastocystis is a common single-celled intestinal parasite of humans and other animals comprising at least 17 genetically distinct small subunit ribosomal RNA lineages (subtypes (STs)), nine of which have been ... -
Distribution power factor monitoring in presence of high RES integration using a modified load encroachment technique
( Institution of Engineering and Technology , 2018 , Article)This study presents a new approach in application of distance relay in distribution system. During the heavy load conditions, the load encroachment of impedance into the distance relay protection zones is a well-known ... -
Distribution system restoration based on cooperative multi-agent approach
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)This paper presents a robust power restoration mechanism that can operate in typical distribution systems without the need of supervision from a central point or intervention from the operator. The restoration is carried ... -
