Concrete Hydration Model Characterization Using Evolutionary Optimization
( Qatar Univesrity Press , 2020 , Conference Paper)Pile thermal integrity assessment by means of temperature measurement has received increasing attention in recent years. The thermal integrity testing method measures temperature changes during the concrete curing process; ... -
Concrete Pavement Truck Equivalence Factors For Upgrades
( Qatar University , 1999 , Article)Presented in this paper are the upgrade truck equivalence factors for single unit trucks of type, 1.2 and 1.22 which are not covered by AASHTO. The equivalency factors for front and rear axles of single unit trucks were ... -
Concretizing green growth and sustainable business models in the water sector of Jordan
( MDPI AG , 2019 , Article)The green growth paradigm has gained much attention from various governments worldwide as a guiding strategy for national and sectoral growth strategies. There is, however, little knowledge on how to integrate green growth ... -
Concurrent adsorption of cationic and anionic dyes from environmental water on amine functionalized carbon
( IWA Publishing , 2020 , Article)Amine functionalized carbon (AFC) was synthesized from raw oil fly ash and later utilized it for simultaneous removal of methyl orange (MO) and rhodamine 6G (Rh6G) pollutant dyes from aqueous medium. AFC was analyzed through ... -
Concurrent association in heterogeneous networks with underlay D2D communication
( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)Deployment of Device-to-Device (D2D) communication within dense heterogeneous networks is a key solution in order to face the intense demand for high data rates and quality of the service in future 5G networks. However, ... -
Concurrent frequency-voltage stabilization for hybrid microgrid with virtual inertia support
( John Wiley and Sons Inc , 2023 , Article)This paper presents a novel control scheme for combined frequency and voltage stabilization of an islanded multi-generator hybrid microgrid (IHμG). The control concept incorporates an improved virtual inertia support scheme ... -
Concurrent validity and within-session reliability of gait kinematics measured using an inertial motion capture system with repeated calibration
( Elsevier , 2020 , Article)IntroductionWearable inertial measurement units (IMUs) enable gait analysis in the clinic, but require calibrations that may affect subsequent gait measurements. This study assessed concurrent validity and within-session ... -
Condenser capacity and hyperbolic diameter
( Elsevier , 2021 , Article)Given a compact connected set E in the unit disk B2, we give a new upper bound for the conformal capacity of the condenser (B2,E) in terms of the hyperbolic diameter t of E. Moreover, for t>0, we construct a set of hyperbolic ... -
Condenser capacity and hyperbolic perimeterImage 1
( Elsevier , 2021 , Article)We study the conformal capacity by using novel computational algorithms based on implementations of the fast multipole method, and analytic techniques. Especially, we apply domain functionals to study the capacities of ... -
Condition and trend of a depression-type habitat In rainfed desert rangelands of Qatar In response to fertilizer application
( Qatar University , 1994 , Article)Characteristics of a rainfed depression-type habitat in desert ranges, and its response to fertilizer application were studied. A single fertilizer application at a rate of 75 Kg ha1 prior to the rainy season improved range ... -
Condition assessment model for sewer pipelines using fuzzy-based evidential reasoning
( Taylor and Francis Ltd. , 2018 , Article)A condition assessment model for gravity and pressurised sewer pipelines using Fuzzy Set Theory (FST), and Evidential Reasoning (ER) with the aid of Fuzzy Analytical Network Process (FANP) integrated with Monte-Carlo ... -
Condition Assessment Models for Sewer Pipelines
(2017 , Master Thesis)Underground pipeline system is a complex infrastructure system that has significant impact on social, environmental and economic aspects. Sewer pipeline networks are considered to be an extremely expensive asset. This study ... -
Condition assessment of sewer pipelines using multi attribute utility theory (MAUT)
( International Society for Trenchless Technology , 2016 , Conference Paper)Many municipalities rely on the interpretation of Closed Circuit Television (CCTV) inspection reports to arrive to a condition assessment grade for the inspected sewer pipelines. The grades stand as a key for decision ... -
Condition prediction models for oil and gas pipelines using regression analysis
( American Society of Civil Engineers (ASCE) , 2014 , Article)Although they are the safest means of transporting oil and gas products, pipelines can sometimes fail with hazardous consequences and large business losses. The decision to replace, repair, or rehabilitate depends mainly ... -
Conditional dependence structure and risk spillovers between Bitcoin and fiat currencies
( Elsevier , 2023 , Article)This paper investigates the extreme dependence and risk spillovers between Bitcoin and the currencies of the BRICS and G7 economies. We find time-varying dependence between Bitcoin and all currencies. Moreover, when analysing ... -
Conditionally Exponential Convex Functions On Locally Compact Groups
