Event-Triggered Suboptimal Tracking Controller Design for a Class of Nonlinear Discrete-Time Systems
( Institute of Electrical and Electronics Engineers Inc. , 2017 , Article)In this paper, using the state-dependent Riccati equation approach, an event-triggered technique is proposed to solve the tracking problem for a broad class of nonlinear discrete-time networked control systems. It is shown ... -
EveTAR: A new test collection for event detection in Arabic tweets
( Association for Computing Machinery, Inc , 2016 , Conference Paper)Research on event detection in Twitter is often obstructed by the lack of publicly-available evaluation mechanisms such as test collections; this problem is more severe when considering the scarcity of them in languages ... -
EveTAR: building a large-scale multi-task test collection over Arabic tweets
( Springer Netherlands , 2018 , Article)This article introduces a new language-independent approach for creating a large-scale high-quality test collection of tweets that supports multiple information retrieval (IR) tasks without running a shared-task campaign. ... -
Evidence by ac-conductivity for the higher mobility of boron (over aluminium)-associated Brønsted sites in boron-modified HZSM-5
( Elsevier , 1996 , Article)A correlation ac-conductivity analysis is performed at 102–105 Hz, 373–613 K and 0.8 V for characterizing the effect of increasing boron incorporation in HZSM-5 lattice on altered electric features in BZSM-5 samples of ... -
Evidence for gesture-speech mismatch detection impairments in schizophrenia
( Elsevier Ireland Ltd , 2019 , Article)Patients with schizophrenia suffer from impairments in the perception and production of gestures. The extent to which patients can access the semantic association between speech and co-verbal gestures in concrete or ... -
Evidence for some prostaglandins in Allium sativum extracts
( John Wiley & Sons, Ltd. , 1988 , Article)Homogenized garlic (Allium sativum Linn.) was extracted successively with organic solvents and the prostaglandin-rich fraction separated. Fractionation of the extract with column chromatography was performed. TLC of the ... -
Evidence of a Role for Aerobic Bacteria in High Magnesium Carbonate Formation in the Evaporitic Environment of Dohat Faishakh Sabkha in Qatar
( Frontiers Media , 2017 , Article)Dolomite (MgCa(CO3)2) is an important petroleum reservoir rock mineral common in ancient sedimentary rocks which is infrequently found in modern environments. The mechanism of dolomite formation remains poorly understood, ... -
Evidence of adverse selection in automobile insurance market: A seemingly unrelated probit modelling
( Cogent OA , 2017 , Article)The present paper investigates the adverse selection problem by examining the relationship between accident occurrences and deductible choice utilizing a seemingly unrelated probit model that allows for best controls for ... -
Evidence of community pharmacists' response preparedness during COVID-19 public health crisis: A cross-sectional study
( Journal of Infection in Developing Countries , 2021 , Article)Introduction: Community pharmacists are often the first point of contact for the public, especially during pandemics. As outlined by the International Pharmaceutical Federation, community pharmacists have an important ... -
Evidence of low levels of aflatoxin M1 in milk and dairy products marketed in Qatar
( Elsevier Ltd , 2018 , Article)This study was designed to explore the incidence of aflatoxin M1 (AFM1) in milk and dairy products marketed in Qatar. Milk (n = 72), yogurt (n = 21), cheese (n = 46), butter (n = 18) and laban (n = 25) samples were initially ... -
Evidence of the drying technique’s impact on the biomass quality of Tetraselmis subcordiformis (Chlorophyceae)
