A wavelet approach for profile monitoring of Poisson distribution with application
( Taylor and Francis Inc. , 2019 , Article)Profile monitoring is defined as the act of utilizing regression and quality control techniques to monitor the functional relationship between a response variable and one or more regressors. Most of the previous studies ... -
A weighted version of Hermite-Hadamard type inequalities for strongly GA-convex functions
( Institute of Advanced Science Extension (IASE) , 2020 , Article)In this paper, we have established new weighted Hermite-Hadamard type inequalities for strongly GA-convex functions. Those findings are obtained by using geometric symmetry of continuous positive mappings and differentiable ... -
Ab initio study on the formation of triiodide CT complex from the reaction of iodine with 2,3-diaminopyridine
( Elsevier , 2010 , Article)The charge transfer (CT) interaction between iodine and 2,3-diaminopyridine (DAPY) has been thoroughly investigated via theoretical calculations. A Hartree–Fock, 3-21G level of theory was used to optimize and calculate the ... -
Aberrant driving behaviors as mediators in the relationship between driving anger patterns and crashes among taxi drivers: An investigation in a complex cultural context
( Taylor & Francis , 2023 , Article)Objective: Taxis have become an integrated component of Qatar’s urban transportation network due to their convenience, comfort, and flexibility. Qatar has seen an uptick in the demand for professional taxi drivers. Most ... -
Abiotic stress applied to Tetraselmis subcordiformis reveals enhanced metabolic responses and increased production of Omega-3 fatty acids: A Metabolomic approach
( Elsevier , 2023 , Article)The appeal of high value algal metabolites is certain due to their sustainability, low energy and space requirements. Yet, commercial-level production of such products is limited and has the potential to be enhanced. In ... -
