( Taylor & Francis , 2021 , Article)Cardiogenic shock (CS) is an acute complex condition leading to morbidity and mortality. Vasoactive medications, such as vasopressors and inotropes are considered the cornerstone of pharmacological treatment of CS to improve ... -
Vector anisotropic filter for multispectral image denoising
( SPIE , 2015 , Conference Paper)In this paper, we propose an approach to extend the application of anisotropic Gaussian filtering for multi- spectral image denoising. We study the case of images corrupted with additive Gaussian noise and use sparse matrix ... -
Vector control of multiphase induction machine under open-circuit phase faults
( IEEE Computer SocietyIEEE , 2013 , Conference Paper)Multiphase induction machine is normally controlled using rotor field oriented vector control. Under phase(s) loss, the machine currents can be optimally controlled to satisfy certain optimization criteria. In this paper, ... -
Vegetation composition of a maritime salt marsh in Qatar in relation to edaphic features
( Blackwell Publishing Ltd , 1990 , Article)Coverpercentage values for plant species were estimated using the line-intercept method along two belt transects starting at the lower mangrove frontier and ending at the upper height of the salt marsh. Twelve perennial ... -
Vegetative insecticidal protein of Bacillus thuringiensis BLB459 and its efficiency against Lepidoptera
( Elsevier Ltd , 2017 , Article)Bacillus thuringiensis strain BLB459 supernatant showed a promising activity against Lepidopteran pests with extremely damages in the larvae midgut. Investigations of the genes that encode secreted toxin demonstrated that ... -
Vehicle identification using optimised ALPR.
( Qatar University Press , 2021 , Poster)Vehicles are a common sight on the road. Tracking and monitoring suspicious vehicles for identification due to high similarity in structure and form leads to difficulties in differentiating between them. The unique identity ... -
Vehicle routing problem in omni-channel retailing distribution systems
( Elsevier B.V. , 2018 , Article)This paper introduces a variant of the vehicle routing problem where a group of retail stores are served from a distribution center using a fleet of vehicles. Moreover, products are distributed to consumers from some of ... -
Vehicle-to-grid technology for cost reduction and uncertainty management integrated with solar power
( Elsevier Ltd , 2019 , Article)This paper optimizes the operation of electric vehicles in small charging stations deployed in electrical distribution networks. The grid is equipped with small-scale charging stations rather than one large-scale charging ... -
Vehicular Crowd Management: An IoT-Based Departure Control and Navigation System
( Institute of Electrical and Electronics Engineers Inc. , 2020 , Conference Paper)Large sport and entertainment events such as soccer games or concerts attract an immense number of fans, most of whom use personal vehicles to get to the event. Such a large number of cars presents a 'vehicular crowd' that ... -
Venous Thromboembolism Among Hospitalized Patients: Incidence and Adequacy of Thromboprophylaxis – A Retrospective Study
( Taylor & Francis Group , 2022 , Article)Purpose: We aimed to determine the incidence of venous thromboembolism among hospitalized patients in Qatar as well as to analyze the adequacy of VTE assessment and prophylaxis in hospitalized patients. Design: Retrospective ... -
Ventifacts distribution in Qatar
( John Wiley & Sons, Ltd , 1985 , Article)This study attempts to investigate the distribution of ventifacts in Qatar. It is believed that ventifacts are confined to the areas within about 5 km of the Miocene or Mio-Pliocene Hofuf formations and the spreads of ... -
Ventilator-associated pneumonia diagnosis: electrochemical sensors for rapid and sensitive detection of pyocyanin
( Springer Nature , 2024 , Article)Ventilator-associated pneumonia (VAP) is a severe condition in critically ill patients that requires timely diagnosis to improve patient outcomes. In this study, we developed an electrochemical sensor for pyocyanin detection ... -
Verification of ACI- 549 Code for Flexural Strengthening of Reinforced Concrete Beams Using FRCM
( Qatar Univesrity Press , 2020 , Conference Paper)This paper presents an analytical study to verify the ACI 549-4R-16 code for experimentally tested Reinforced Concrete (RC) beams, which were strengthened to enhance the flexural capacity using Fiber-Reinforced Cementitious ... -
Verifying cloud service-level agreement by a third-party auditor
( John Wiley & Sons, Ltd. , 2014 , Article)In this paper, we study the important issue of verifying service-level agreement (SLA) with an untrusted cloud and present an SLA verification framework that utilizes a third-party auditor (TPA). A cloud provides users ... -
