Malaysian PBL Approaches: Shaping World-Class TVET Skills towards IR 4.0
An Industrial Revolution 4.0 promoted by Malaysian government entitles the rapid growth of
manufacturing sector thus promotes a multi-level of workforce and skilled work force needed to satisfy the rapid
technological development application. The challenges arise on preparing the individuals to meet with the
current business at adequate skills level and the student need to be prepared in such way satisfied the business
expectations. Looking into this situation, this paper aims to study the concept of correlation between active
learning method known as Problem-Based Learning (PBL) Method and required employability skills in TVET.
As an initiative to enrich the future opportunity on empowering TVET skills, this study assumes that there is
positive relationship between employability skills and PBL approaches in improving student’s quality and skills.
The method of study involves documentation analysis on previous research to proves the importance of
employability skills in enhancing student’s competencies and the effectiveness of Problem-Based Learning
Method in preparing the students to meet the expectations. The main findings of this study claimed that there
was a positive relationship between employability skills and PBL learning method. Result acknowledge that
PBL has the ingredients to help develop employability skills and student’s behavior. Through PBL, students
learn to become more associates in the teaching and learning processes as they take responsibility throughout
the learning process. It would suggest that the educational institution should emphasize the needs of the
industry and students by creating awareness and guiding the students in self-analysis and in acquisition of
skills
Admonian's method for Hammerstein integral equations arising from chemical reactor theory
An ordinary differential equation with a parameter in the boundary conditions describes the steady state in an adiabatic tubular chemical reactor. In this paper, the problem is considered as a Hammerstein integral equation and solutions are obtained using Adomian's decomposition method
Reduced Differential Transform Method for (2+1) Dimensional type of the Zakharov-Kuznetsov ZK(n,n) Equations
In this paper, reduced differential transform method (RDTM) is employed to
approximate the solutions of (2+1) dimensional type of the Zakharov-Kuznetsov
partial differential equations. We apply these method to two examples. Thus, we
have obtained numerical solution partial differential equations of
Zakharov-Kuznetsov. These examples are prepared to show the efficiency and
simplicity of the method
Additional degrees of parallelism within the Adomian decomposition method
4th International Conference on Computational Engineering (ICCE 2017), 28-29 September 2017, DarmstadtThis is the author accepted manuscript. The final version is available from Springer via the DOI in this record.The trend of future massively parallel computer architectures challenges the exploration of additional degrees of parallelism also in the time dimension when solving continuum mechanical partial differential equations. The Adomian decomposition method (ADM) is investigated to this respects in the present work. This is accomplished by comparison with the Runge-Kutta (RK) time integration and put in the context of the viscous Burgers equation. Our studies show that both methods have similar restrictions regarding their maximal time step size. Increasing the order of the schemes leads to larger errors for the ADM compared to RK. However, we also discuss a parallelization within the ADM, reducing its runtime complexity from O(n^2) to O(n). This indicates the possibility to make it a viable competitor to RK, as fewer function evaluations have to be done in serial, if a high order method is desired. Additionally, creating ADM schemes of high-order is less complex as it is with RK.The work of Andreas Schmitt is supported by the ’Excellence

Numerical resolution of Emden's equation using Adomian polynomials
Purpose: In this paper the authors aim to show the advantages of using the decomposition method introduced by Adomian to solve Emden's equation, a classical non‐linear equation that appears in the study of the thermal behaviour of a spherical cloud and of the gravitational potential of a polytropic fluid at hydrostatic equilibrium. Design/methodology/approach: In their work, the authors first review Emden's equation and its possible solutions using the Frobenius and power series methods; then, Adomian polynomials are introduced. Afterwards, Emden's equation is solved using Adomian's decomposition method and, finally, they conclude with a comparison of the solution given by Adomian's method with the solution obtained by the other methods, for certain cases where the exact solution is known. Findings: Solving Emden's equation for n in the interval [0, 5] is very interesting for several scientific applications, such as astronomy. However, the exact solution is known only for n=0, n=1 and n=5. The experiments show that Adomian's method achieves an approximate solution which overlaps with the exact solution when n=0, and that coincides with the Taylor expansion of the exact solutions for n=1 and n=5. As a result, the authors obtained quite satisfactory results from their proposal. Originality/value: The main classical methods for obtaining approximate solutions of Emden's equation have serious computational drawbacks. The authors make a new, efficient numerical implementation for solving this equation, constructing iteratively the Adomian polynomials, which leads to a solution of Emden's equation that extends the range of variation of parameter n compared to the solutions given by both the Frobenius and the power series methods.This work has been supported by the Ministerio de Ciencia e Innovación, project TIN2009-10581
