Optimal Production Planning Strategy for Deteriorating Items in Terms of Emission Tax, Pollution, and R&D Investment
( Springer Science and Business Media B.V. , 2018 , Conference Paper)Firms are faced with the question of what policies to implement to ensure efficient abatement behavior? In this paper, we aim to determine the optimal production rate and the optimal investment rate in pollution abatement ... -
Optimization design of the CUSUM and EWMA charts for autocorrelated processes
( John Wiley and Sons Ltd , 2017 , Article)The traditional control charts produce frequent false alarm signals in the presence of autocorrelation. The implementation of the modified chart scheme is a way of handling the problem of autocorrelation in control charts. ... -
Optimization of tank engine crank shaft material properties
( Taylor and Francis Ltd. , 2023 , Article)Metals and coating materials, with best material properties are highly desired in the field of engineering to control the stresses and strains, that play important role in design strategies. The crankshaft, an important ... -
Ordered Sp -metric spaces and some fixed point theorems for contractive mappings with application to periodic boundary value problems
( Springer International Publishing , 2019 , Article)In this paper, we introduce the structure of Sp-metric spaces as a generalization of both S-metric and Sb-metric spaces. Also, we present the notions of S?-contractive mappings in the setup of ordered Sp-metric spaces and ... -

Orientation dependence in multiple ionization of He 2 and Ne 2 induced by fast, highly charged ions: Probing the impact-parameter-dependent ionization probability in 11.37-MeV/u S 14 + collisions with He and Ne
( American Physical Society , 2014 , Article)We investigate orientation effects in the fragmentation of He2 and Ne2 induced by S14+ projectiles at an impact energy of 11.37 MeV/u. Multiple ionization shows a strong dependence on the orientation of the dimer axis with ... -
Oscillatory Singular Integral Operators with Hölder Class Kernels
( Birkhauser Boston , 2019 , Article)We establish the boundedness on Lp(Rn) of oscillatory singular integral operators whose kernels are the products of an oscillatory factor with bilinear phase and a Calderón–Zygmund kernel K(x, y) satisfying a Hölder ... -
Outlier robust nonlinear mixed model estimation
( John Wiley & Sons, Ltd. , 2015 , Article)In standard analyses of data well-modeled by a nonlinear mixed model, an aberrant observation, either within a cluster, or an entire cluster itself, can greatly distort parameter estimates and subsequent standard errors. ... -
Overlapping Schwarz waveform relaxation method for the solution of the convection-diffusion equation
( John Wiley & Sons, Ltd. , 2008 , Article)In this article we study the convergence of the overlapping Schwarz wave form relaxation method for solving the convection-diffusion equation over multi-overlapped subdomains. It is shown that the method converges linearly ... -
Oyster oscillator: a novel mega-stable nonlinear chaotic system
( Springer , 2021 , Article)Designing novel mega-stable chaotic oscillators has been a hot topic of research lately. In the current paper, a two-dimensional mega-stable oscillator is presented. The oscillator has a vast amount of coexisting limit ... -
Parallel LQP alternating direction method for solving variational inequality problems with separable structure
( Springer International Publishing , 2014 , Article)In this paper, we propose a logarithmic-quadratic proximal alternating direction method for structured variational inequalities. The predictor is obtained by solving series of related systems of nonlinear equations, and ... -
Parameter estimation in a new chaotic memristive system using ions motion optimization
( Springer Verlag , 2019 , Article)In this paper, a new four-dimensional nonlinear oscillator is introduced. This oscillator is memristive and can exhibit chaotic behavior. A complete dynamical analysis is done on each parameter of this system by the help ... -
Parametric Model Based on Imputations Techniques for Partly Interval Censored Data
( Institute of Physics Publishing , 2018 , Conference Paper)The term 'survival analysis' has been used in a broad sense to describe collection of statistical procedures for data analysis. In this case, outcome variable of interest is time until an event occurs where the time to ... -
Patient Counseling Practices among Community Pharmacists in Qatar
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)Patient counseling is a term used in the field of pharmacy to describe the communication that takes place between a pharmacist and a patient in regards to his or her medication therapy. Patient counseling is deemed to be ... -
PbS/CdS heterojunction quantum dot solar cells
( Springer New York LLC , 2016 , Article)The present work investigates the effects of combination of lead sulfide PbS quantum dots and cadmium sulfide CdS nanoparticles (NPs), with n-type and p-type semiconductors, on the photovoltaic performance of heterojunction ... -
Penalty ADM Algorithm for Cardinality Constrained Mean-Absolute Deviation Portfolio Optimization
( International Academic Press , 2022 , Article)In this paper, we study the cardinality constrained mean-absolute deviation portfolio optimization problem with risk-neutral interest rate and short-selling. We enhance the model by adding extra constraints to avoid investing ... -
