Sequential random selection relaying for energy efficient wireless sensor networks
( IEEE , 2010 , Conference Paper)In a wireless sensor network with relaying capability, intermediate relay nodes are with limited energy budget. To maximize lifetime of relay nodes, selective relay strategies, requiring full channel state information ... -
Single-sensor-based three-phase permanent-magnet synchronous motor drive system with luenberger observers for motor line current reconstruction
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Article)This paper presents an algorithm that enables single-sensor operation of vector-controlled three-phase permanent-magnet-synchronous-motor voltage source inverter (VSI)-based drive systems. The closed-loop operation is ... -
Small data dissemination for wireless sensor networks: The security aspect
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Article)In wireless sensor networks small data dissemination protocols are used to adjust configuration parameters of sensors, or distribute management commands and queries to sensors. For security reasons every disseminated data ... -
Smart Technologies Driven Approaches to Tackle COVID-19 Pandemic
( Qatar University Press , 2020 , Poster)The emergence of Severe Acute Respiratory Syndrome Corona Virus 2 (SARS-CoV-2) had led to a global outbreak of corona virus disease 2019 (COVID-19) and raised an international public health issue. To mitigate the infection ... -
Substituted 2-aminobenzothiazoles salicylidenes synthesis and characterization as cyanide sensors in aqueous medium
( MDPI AG , 2018 , Article)(E)-2-((benzo[d]thiazol-2-ylimino)methyl)-4-nitrophenol 1 and (E)-2-(((6-methoxybenzo[d]thiazol-2-yl)imino)methyl)-4-nitrophenol 2 were synthesized efficiently under microwave conditions. The structures were confirmed using ... -
A survey of cyber-physical attacks and detection methods in smart water distribution systems
( Institute of Electrical and Electronics Engineers Inc. , 2021 , Article)Modern technologies empower water distribution systems (WDS) for better services in the processes of water supply, storage, distribution, and recycling. They improve real-time monitoring, automating, and managing. However, ... -
Synthesis, optimization and applications of ZnO/polymer nanocomposites
