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 Changes in the Long Abandoned Farms in Qatar
( Qatar University , 1984 , Article)An attempt was made in this study to investigate the changes that occur in vegetation cover in the totally abandoned farms in Qatar. An effort was also made to compare the vegetation communities found in the abandoned farms ... -
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 ... -
The vegetation of the state of Qatar as related to landform and soil.
( Qatar University , 1990 , Article)The effect of landform and soil on the vegetation of the State of Qatar is described. Five major landform/soil subdivisions are recognized; depressions, wadis, rocky and conglomerate hammada surfaces, sand dunes and sabkhas. ... -
Vegetation responses to 26 years of warming at Latnjajaure Field Station, northern Sweden
( NRC Research Press , 2021 , Article)Climate change is rapidly warming high latitude and high elevation regions influencing plant community composition. Changes in vegetation composition have motivated the coordination of ecological monitoring networks across ... -
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 ... -
VEGF-121 plasma level as biomarker for response to anti-angiogenetic therapy in recurrent glioblastoma.
( BioMed Central , 2018 , Article)Vascular endothelial growth factor (VEGF) isoforms, particularly the diffusible VEGF-121, could play a major role in the response of recurrent glioblastoma (GB) to anti-angiogenetic treatment with bevacizumab. We hypothesized ... -
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 Inspection Policy and Emission Analysis in Kuwait
( Qatar Univesrity Press , 2020 , Conference Paper)"Technical vehicle inspection centers are widespread in Kuwait. All vehicles should pass the test every two years if not older than six years or every one-year for other vehicles. This study provided an insight into the ... -
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 ... -
