Appraising e-commerce systems performance in the engineering and information technology industry
(2015 , Other)This research aimed to understand the factors influencing e-commerce systems performance in Jordan. Using previous literature, we developed a theoretical model of performance with four contributing factors: perceived ... -
An Approach for Adjusting the Laboratory-Determined Dynamic Modulus Master Curve of Asphalt Layers Based on Falling Weight Deflectometer Measurements
( Hindawi , 2023 , Article)Structural assessment is critical for designing asphalt pavement overlays, estimating the remaining life of pavements, and selecting an appropriate rehabilitation strategy for existing pavements. The falling weight ... -
An approach for constructing complex discriminating surfaces based on Bayesian interference of the maximum entropy
( Elsevier Inc. , 2003 , Article)In this paper we present a comprehensive Maximum Entropy (MaxEnt) procedure for the classification tasks. This MaxEnt is applied successfully to the problem of estimating the probability distribution function (pdf) of a ... -
Approach for Integrating Indirect Evaporative Cooling System into Contemporary Architecture
( OMICS International , 2014 , Article)Nowadays, the knowledge of building ecology focuses on energy efficiency and how to integrate environmental and climatic parameters into HVAC and thus enhances space qualities such as comfort ability. The aim of this paper ... -
Approaches to achieve sustainable use and management of groundwater resources in Qatar
( Qatar University Press , 2020 , Poster)This paper reviews the hydro-geochemical characterization of Qatar's aquifer. In addition, it highlights the opportunities in the current groundwater management practices to achieve a sustainable groundwater use in Qatar ... -
Approaches to Critical Digital Literacy in the MENA Region
( Qatar University Young Scientists Center - Qatar University , 2024 , Conference Paper)This research paper aims to propose a viable solution to one of the world’s most dire issues as of this decade, and most specifically within the MENA region. It is the proliferation of fake news, and misinformation that ... -
Approaches to Direct Oral Anticoagulant Selection in Practice
( SAGE Publications Ltd , 2019 , Article Review)Direct oral anticoagulants (DOACs) carry many advantages over warfarin and are now considered first line or an alternative for mnay thromboembolic disorders. With the emergence of 5 DOAC agents to the market as well as the ... -
Approaches to searching the literature

Approaching what we hope for and avoiding what we fear: A study of women's concern with visible signs of skin aging
( SAGE , 2011 , Article)This paper proposes to examine how priming approach and avoidance goal orientations moderates consumer goal-directed preferences for products and services. These effects are studied in the context of women's concern with ... -
Appropriateness of Dabigatran and Rivaroxaban Prescribing in Qatar: A 5-Year Experience
( SAGE Publications Ltd , 2018 , Article)Introduction: Over the past few years, direct oral anticoagulants (DOACs) have been gradually replacing warfarin. Inappropriate prescribing of DOACs in real-life practice settings can affect their perceived safety and ... -
Approving updates in collaborative databases
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)Data curation activities in collaborative databases mandate that collaborators interact until they converge and agree on the content of their data. Typically, updates by a member of the collaboration are made visible to ... -
Approximate analytic solutions of transient nonlinear heat conduction with temperature-dependent thermal diffusivity
( Hindawi Publishing Corporation , 2014 , Article)A new approach for generating approximate analytic solutions of transient nonlinear heat conduction problems is presented. It is based on an effective combination of Lie symmetry method, homotopy perturbation method, finite ... -
Approximate methods for optimal replacement, maintenance, and inspection policies
( Elsevier , 2015 , Article)It might be difficult sometimes to derive theoretical and numerical solutions for analytical maintenance modelings due to the computational complexity. This paper takes up several approximate models in maintenance theory, ... -
Approximate Solution For A Problem Of Propagation Of Elastic-Plastic Wave In The Half-Space
( Qatar University , 1984 , Article)In this paper, we consider a half-space occupying an elastic-plastic medium. Treatments were carried out under the assumption of perpendicular load, on boundary which propagates with a constant speed D. The assumption ... -
Approximate solutions to the generalized time-fractional ito system
( Forum-Editrice Universitaria Udinese SRL , 2017 , Article)In this work, we consider the time-fractional version of the well-known integrable Ito system to study the effect of its fractional index "memory index". A modified approach of a relatively new method called residual power ... -
Approximating the Distribution of Quadratic Forms Using Orthogonal Polynomials
( Qatar University , 1999 , Article)In this paper we propose some techniques to approximate the distribution of quadratic forms in normal random variables. The first two techniques will be based on orthogonal polynomials, namely; the Hermitte and Laguerre ... -
Approximating the tail probabilities of the longest run in a sequence of Bernoulli trials
( Taylor and Francis Ltd. , 2018 , Article)We consider the longest run of either successes or failures in a sequence of (Formula presented.) Bernoulli trials. The exact distribution of this random variable is obtained using probability generating function techniques. ... -
An Approximation Leading To The Binomial Distribution In The Stochastic Treatment Of A Reversible Chemical Reaction
( Qatar University , 1992 , Article)The exact equilibrium distribution of the number of molecules of C in the reversible chemical reaction A+B ^=S: C is shown to converge to the binomial distribution when N is finite, M—»!K, K—>0 in such a way that KM is ... -
Approximation of Pore Space with Ellipsoids: A Comparison of a Geometrical Method with a Statistical one
( Institute of Electrical and Electronics Engineers Inc. , 2018 , Conference Paper)We work with tomographic images of pore space in soil. The images have large dimensions and so in order to speed-up biological simulations (as drainage or diffusion process in soil), we want to describe the pore space with ... -
