3-D Modeling of Axial Fans
(2013)In this paper we present a full-geometry Computational Fluid Dynamics (CFD) modeling of air flow distribution from an automotive engine cooling fan. To simplify geometric modeling and mesh generation, different solution ... -
A new matrix method for solving two-dimensional time-dependent diffusion equations with Dirichlet boundary conditions
(2016)This paper is devoted to develop a new matrix scheme for solving two-dimensional time-dependent diffusion equations with Dirichlet boundary conditions. We first transform these equations into equivalent integro partial ... -
An accurate space time pseudospectral method for solving nonlinear multi-dimensional heat transfer problems
(2017)In this paper, we consider the numerical solution of the nonlinear one- and two-dimensional heat transfer problems subject to the given initial conditions and linear Robin boundary conditions. We propose a pseudospectral ... -
Approximations to the t distribution
(2015)In this paper, a few formulas are found to approximate the t cumulative distribution function. The formulas found in [5] to approximate the normal distributions are used to get good approximations for t. The derived ... -
Asymptotic Sampling Distribution of Inverse Coefficient of Variation and its Applications: Revisited
(2014)Sharma and Krishna (1994) derived mathematically an appealing asymptotic confidence interval for the population signal-to-noise ratio (SNR). In this paper, an evaluation of the performance of this interval using monte carlo ... -
Bernoulli collocation method for solving linear multi-dimensional diffusion and wave equations with Dirichlet boundary conditions
(2017)A numerical approach is proposed for solving multidimensional parabolic diffusion and hyperbolic wave equations subject to the appropriate initial and boundary conditions. The considered numerical solutions of the these ... -
Elementary Statistics: A Step by Step Approach

How many clusters exist? Answer via maximum clustering similarity implemented in R
(Taylor & Francis, 2019)Finding the number of clusters in a data set is considered as one of the fundamental problems in cluster analysis. This paper integrates maximum clustering similarity (MCS), for finding the optimal number of clusters, into ... -
Improved confidence interval estimation of the population standard deviation using ranked set sampling: A simulation study
(Journal of Biostatistics and Epidemiology, 2018)The sample standard deviation S is the common point estimator of σ, but S is sensitive to the presence of outliers and may not be an efficient estimator of σ in skewed and leptokurtic distributions. Although S has good ... -
Method of lines for multi-dimensional coupled viscous Burgers' equations via nodal Jacobi spectral collocation method
(Physica Scripta, IOP Science, 2021-08-27)This paper deals with the multi-dimensional coupled viscous Burgers' equations, using the method of lines (MOL). Indeed, the solutions are approximated by their Lagrange interpolation on a set of Jacobi-type nodes. Then, ... -
On the Optimality of Escalating Penalties for Repeat Offenses Against the Academic Honor Code
(2015)Although academic dishonesty has a long history in academia, its pervasiveness has recently reached an alarming level. Academic dishonesty not only undermines the purpose of education and the assessment process but also ... -
Parental Control: the Relationship Amongst Parental Supervision, Education, Income and Children's Viewing Habits
(2014)This paper explores children’s relationship with TV and influence of parental mediation on that relationship by examining factors such as parents’ income, marital status, age, education, religion and the effects of the ... -
Personality Traits as Predictors of Social Networks Addiction among University Students
(2015)Social network platforms (SNPs) are online sites that enable users to create public profiles, interact with real-life friends, and meet other people based on common interests and beliefs. Given their social-oriented ... -
Psychometric Properties of the Arabic Version of the Pittsburgh Sleep Quality Index in Hemodialysis Patients
(Sleep and Vigilance, 2022-07-27)The Pittsburgh Sleep Quality Index (PSQI) is widely used in screening for self-reported sleep disturbances in clinical groups or healthy populations. The literature lacks rigorous psychometric evaluation of the Arabic ... -
Students’ Perception of Cell Phones Effect on their Academic Performance: A Latvian and a Middle Eastern University Cases
(Technology, Knowledge and Learning by Springer, 2021-04-15)This study is unique in its attempt to combine the Technology Acceptance Model (TAM) with external variables and the Information System Continuance Theory, in the context of mobile learning. It extends TAM with the external ... -
Study of University Students' Achievement in Low-Level Mathematics Classes
(2013)The purpose of this study was to compare students' achievement in college algebra classes in two different universities, and to explore factors that might affect such achievement. Two groups of students were considered in ... -
Surface Grid Generation
Grid generation technology has long been recognized as a critical issue in practical applications of computational fluid dynamics analyses [7]. Methods have been developed to implement geometry modeling technologies in ... -
The Role of MathXL in the Online Learning of Algebra
(2012)The purpose of this study is to explore and describe the impact that platforms such as MathXL can have on students’ attitudes and performance in college algebra classes. MathXL is an innovative series of text-specific ... -
University Students' Achievement in Mathematics: The Role of Student's Gender, Instructor's Gender, Educational Level, and Experience
(2015)Educational research that investigated the influence of gender on university students’ mathematics achievement has focused mainly on student gender. The role played by instructors in determining such achievement has always ...
