Calculation of derating factors based on steady-state unbalanced multiphase induction machine model under open phase(s) and optimal winding currents
( Elsevier , 2014 , Article)Multiphase machines have become a promising candidate in high-power applications as they offer many advantages over their three-phase counterparts. The main salient feature is the high fault tolerance capability. During ... -
Calculation Of Mass Yield Distributions In Fission Induced By High Energy Protons
( Qatar University , 1991 , Article)An analytical expression is obtained for the mass-yield distribution in fission induced by high-energy protons, using a two-step model. In the first step, the incident proton penetrates the target nucleus, knocking out ... -
Calibration & Temperature Controlled Setup for Air Quality Sensors
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)Indoor air pollution is a major issue affecting public health. Due to hot climate, humidity and lack of natural green spaces, life is mostly confined indoors in many countries of the MENA region. Vulnerable population, ... -
Calibration of the double Heston model and an analytical formula in pricing American put option
( Elsevier B.V. , 2021 , Article)This paper proposes a novel approach to pricing of American put option under double Heston model. We develop an analytical solution to the double Heston partial differential equation (double Heston PDE) using the equivalent ... -
Calibration of time features and frequency features in the time-frequency domain for improved detection and classification of seizure in newborn EEG signals
( IEEE Computer Society , 2012 , Conference Paper)This paper presents new time-frequency features for seizure detection in newborn EEG signals. These features are obtained by calibrating relevant time features and frequency features in the joint time-frequency domain. The ... -
Calix[4]arene-clicked clay through thiol-yne addition for the molecular recognition and removal of Cd(II) from wastewater
( Elsevier B.V. , 2020 , Article)A novel type of hybrid Clay/Calix[4]arene (denoted as B-S-Calix), was prepared through fast photo-induced radical-mediated thiol–yne addition between a thiolated clay and an alkynylated calix[4]arene. The photo-induced ... -
Call for emergency action to restore dietary diversity and protect global food systems in times of COVID-19 and beyond: Results from a cross-sectional study in 38 countries
( Elsevier , 2023 , Article)Background The COVID-19 pandemic has revealed the fragility of the global food system, sending shockwaves across countries' societies and economy. This has presented formidable challenges to sustaining a healthy and ... -
A Call to Action to Transform Pharmacy Education and Practice in the Arab World.
( Aacp American Association of Colleges , 2019 , Other)Al-Ghananeem and colleagues recently evaluated health care and pharmacy education in some countries of the Arab world focusing on clinical pharmacy education and practice. They identified six key strategies to meet the ... -
Calmodulin Interacts and Regulates Enzyme Activity of the Mammalian Sperm Phospholipase C
( Elsevier , 2017 , Article)Sperm-specific Phospholipase C zeta (PLCζ) is widely considered to be the sole, physiological stimulus responsible for the generation of Ca2+ oscillations that induce egg activation and early embryo development during ... -
Calmodulin Mutations Associated with Congenital Cardiac Disease Display Novel Biophysical and Biochemical Characteristics
( Elsevier , 2018 , Article)Calmodulin (CaM) is a cytoplasmic multifunctional calcium (Ca2+)-binding messenger that interacts with the cardiac ryanodine receptor (RyR2), a large transmembrane Ca2+ channel that mediates Ca2+ release from the sarcoplasmic ... -
Caloric expenditure estimation for health games
( Hamad bin Khalifa University Press (HBKU Press) , 2013 , Conference Paper)With the decline in physical activities among young people, it is essential to monitor their physical activity and ensure their calorie expenditure is within the range necessary to lead a healthy life style. For many ... -
Calorimetric analysis and molecular dynamics simulation of cure kinetics of epoxy/chitosan-modified Fe3O4 nanocomposites
( Elsevier B.V. , 2017 , Article)Fe3O4 magnetic nanoparticles (MNPs) were synthesized and modified with chitosan as a natural surface modifier to prevent their aggregation and make them potent to contribute to ring opening of epoxy. Functionalized Fe3O4 ... -
Calorimetric and dynamic mechanical behavior of phase change materials based on paraffin wax supported by expanded graphite
( Elsevier , 2015 , Article)This study addressed the characterization and description of calorimetric and dynamic mechanical properties of phase change materials (PCMs) based on linear low-density polyethylene (LLDPE), paraffin wax (W) and expanded ... -
Calreticulin regulates Src kinase in osteogenic differentiation from embryonic stem cells
( Elsevier , 2020 , Article)Calreticulin, the major Ca2+ buffer of the endoplasmic reticulum plays an important role in the choice of fate by embryonic stem cells. Using the embryoid body method of organogenesis, we showed impaired osteogenesis in ...
