Bird strike analysis on a typical helicopter windshield with different lay-ups
( Korean Society of Mechanical Engineers , 2014 , Article)In the current paper, bird strike to a typical helicopter windshield is investigated using smoothed particles hydrodynamic (SPH) finite element method. Five types of lay-ups in a windshield (single layer stretch acrylic, ... -
BIRD-VNE: Backtrack-avoidance virtual network embedding in polynomial time
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference Paper)The virtual network embedding (VNE) problem is known to be NP-hard, and as a result, several heuristic approaches have been proposed to solve it. These heuristics find sub-optimal solutions in polynomial time, but have ... -
Birth and death of spiral waves in a network of Hindmarsh–Rose neurons with exponential magnetic flux and excitable media
( Elsevier Inc. , 2019 , Article)Spiral waves are spatiotemporal patterns, observed in complex networks of biological oscillators such as heart and brain. In this paper, at first a modified Hindmarsh–Rose model with external electromagnetic radiation and ... -
Bismuth perovskite as a viable alternative to Pb perovskite solar cells: device simulations to delineate critical efficiency dynamics
( Springer New York LLC , 2019 , Article)We have simulated the operation and functionality of a working Bi-based perovskite solar cell device using GPVDM and compared it against a Pb-based device. The results are extremely promising in that they showcase comparable ... -
Bite force changes after surgical correction of mandibular prognathism in subjects with increased vertical dimension: A prospective clinical trial
( Springer , 2021 , Article)Purpose: Occlusal bite force (OBF) is the most important parameter in assessing biting efficiency. The aim of this study was to record OBF changes after surgical correction of high angle maxillary/mandibular (Max/Mand) ... -
Bivalent mRNA-1273.214 vaccine effectiveness against SARS-CoV-2 omicron XBB* infections
(2023 , Article)In October of 2022, Qatar introduced COVID-19 bivalent vaccination for persons ≥ 12 years using the 50-μg mRNA-1273.214 vaccine combining SARS-CoV-2 ancestral and omicron BA.1 strains.1 We estimated this vaccine’s effectiveness ... -
Black garlic production: The influence of ageing temperature and duration on some physicochemical and antioxidant properties, and sugar content
( Wiley online library , 2023 , Article)Herein, some quality characteristics (water content, pH, antioxidant activity and sugar contents) of fresh garlic (Taşköprü, Türkiye) and black garlic, which were produced under various ageing temperatures (60 °C, 70 °C ... -
Bladder neoplasms and NF-κB: an unfathomed association.
( Taylor & Francis , 2020 , Article)Bladder cancer is the second most common genitourinary tract cancer and is often recurrent and/or chemoresistant after tumor resection. Cigarette smoking, exposure to aromatic amines, and chronic infection/inflammation are ... -
Blastema Volume And Nuclear Size In The Regenerating Hind Limbs In Larvae Of Xenopus Laevis And Bufo Regularis After Transection At The Ankle Level
( Qatar University , 1990 , Article)After amputation at the ankle level of hind limbs in larval Xenopus laevis and Bufo regularis, an increase in the nuclear volume of blastema and stump tissue cells was observed. The cells in the distal region of blastema ... -
Blended learning in undergraduate dental education: a global pilot study.
( Taylor and Francis Group , 2023 , Article)To explore the global trends in blended learning in undergraduate dental education during the COVID pandemic and during the recovery phase by engaging with the students and faculty and evaluate the implications for dental ... -
Blind deconvolution and retinal abnormality detection in blurred retinal images
( American Scientific Publishers , 2011 , Article)In this paper, a new technique is presented to enhance the blurred images obtained from retinal imaging; both regular as well as Fluorescein Angiography. While in most of the cases, the image produced is quite clean and ... -
Blind Deconvolution for retinal image enhancement
( IEEE , 2010 , Conference Paper)In this paper, a new technique is presented to enhance the blurred images obtained from retinal imaging. One of the main steps in inspecting the eye (especially the deeper image of retina) is to look into the eye using a ...
