This paper reports the use of a numerical solution of nanofluid flow. The boundary layer flow over a stretching sheet in combination of two nanofluids models is studied. The partial differential equation that governs this model was transformed into a nonlinear ordinary differential equation by using similarity variables, and the numerical results were obtained by applying the shooting technique. Copper (Cu) nanoparticles (water-based fluid) were used in this study. This paper presents and discusses all numerical results, including those for the local Sherwood number and the local Nusselt number. Additionally, the effects of the nanoparticle volume fraction, Brownian motion Nb, and thermophoresis Nt on the performance of heat transfer are discussed. The results show that the stretching sheet has a unique solution: as the nanoparticle volume fraction φ (φ = 0), Nt (Nt = 0.1), and Nb decrease, the rate of heat transfer increases. Furthermore, as φ (φ = 0) and Nb decrease, the rate of mass transfer increases. The data of the Nusselt and Sherwood numbers were tested using different statistical distributions, and it is found that both datasets fit the Weibull distribution for different values of Nt and rotating φ.

Project-based learning is an example of active learning and is student-driven, interdisciplinary, collaborative and technology-based. To test the hypothesis that project-based learning maximises course performance, we analysed a difficulty index of examination scores or failure rates and compared between 422 students in the 2016/2017 session, who took the Vector Calculus course and project-based learning with 342 students from the 2015/2016 session without project-based learning. The analysis of the difficulty index is used to investigate the achievement of the course outcome and the analysis on the correlation between the project-based learning scores and the final exam scores are identified using Pearson's product-moment correlation. The effect sizes indicate that on average examination scores improved by about 12% with project-based learning and students in classes with project-based learning were 3.4 times more likely to get as than students in classes without project-based learning. It is observed that the difficulty index for all course outcomes are achieved and distributed between a good range of 0.3–0.8. It is also proven that the students find it easier to answer the exam questions after the project-based learning is implemented based on the results of their mid and final semester exams.

There has been great concern placed on the declining level of mathematical comprehension among engineering students. Earlier identification and classification of the students proves to be vital for future actions. Students profiling is important for any institution especially when the educator seeks to identify the factors of strengths and weaknessess of their students towards any subject knowledge. This paper presents an analysis of 215 students' profiling and Linear Algebra results for semester 1 Academic Session of 2010/2011 from the Faculty of Engineering and Built Environment (FKAB), Universiti Kebangsaan Malaysia (UKM) using the Rasch modeling technique. Students profiling which consists of gender, department, programme, pre-university qualifications and results are used as variables in this study. Students' final results of the Linear Algebra course are also considered as another variable. The major finding was highlighted to be the variables of pre-university qualification and sex, where students with Malaysia Higher School Certificate (STPM) holder and male students have been found to be performing well in this course, as comparison is being drawn to other qualifications and gender.

In this study, the heat and mass transfer characteristics of nanofluid flow over a nonlinearly stretching sheet are investigated. The important effects of axisymmetric of thermal conductivity and viscous dissipation have been included in the model of nanofluids. The Buongiorno model is considered to solve the nanofluid boundary layer problem. The governing nonlinear partial differential equations have been transformed into a system of ordinary differential equations and are solved numerically via the shooting technique. The validity of this method was verified by comparison with previous work performed for nanofluids without the effects of the magnetic field and viscous dissipation. The analytical investigation is carried out for different governing parameters, namely, the Brownian motion parameter, thermophoresis parameter, magnetic parameter, Biot number, and Eckert number. The results indicate that the skin friction coefficient has a direct relationship with the Brownian motion number and thermophoresis number. Moreover, it can be seen that the Nusselt number decreases with the increase of the magnetic parameter and Eckert number.

E-learning is a web-based training which resides on a server or host computer that is connected to the World Wide Web. Elearning has been implemented at the higher education level in Malaysia to help students in certain subjects. The difficulties in the learning of mathematics, as an instance, are well-known and the use of new technologies specifically by using e-learning is an important inducement for both lecturers and students in order to obtain an adequate, or more importantly, an effective transmission of the knowledge. The objective of this research is to identify the significance of implementing e-learning i.e. Wiley-Plus in Vector Calculus at the Faculty of Engineering and Built Environment, Universiti Kebangsaan Malaysia. A set of questionnaire has been distributed to 193 respondents for all four departments and the results show that students are satisfied with the use of Wiley-Plus® in learning process.
