  In this research paper, it will explore the issues regarding the user interface design for elderly mobile phone users and what the factors lead to the limitations of using the mobile applications. Besides, this study also discuss about a mental model, what is it means and how we are going to assess a mental model by using a few methodologies that act as an approach to solving the problem faced by elderly when using particular mobile applications. Moreover, the mental model will work as a vital element in this research because it will affect the interface design that we will develop in future progress. Hence, this research will be an age-related matter as it will only focus on what are the elderly expect in interface design so that hopefully it will increase the elderly’s usability and learnability when using a mobile applications.

  The application of non-linear diffusion equation for image blurring has become a significant study in image processing field. The process is carried out by smoothing the image while preserving the crucial part of the image, i.e., edge, shape and important features using non-linear diffusion equation. However, the classical iterative method to solve the equation requires high number of computations and make the filtering process slower. This study examined 2-EGAOR iterative method as an efficient solver to the image blurring as this method involves two point in one group to solve the linear system with two weighted parameter. For the performance comparison, the results of Successive Over-Relaxation (SOR), Accelerated Over-Relaxation (AOR) and 2-EGAOR iterative methods to develop the equivalent image producing by classical Jacobi method is recorded in this study. The number of iterations and computational time in solving the linear system are used as the evaluation criteria of these iterative methods. Based on the numerical experiment, the findings has shown the 2-EGAOR method able to blurred the image slightly faster as it gives the fewer number of iterations and computational time compared to the other mention methods.

  This study proposed a robot path planning technique that employs Laplacian Behaviour-Based Control (LBBC) for space exploration which relies on the use of Laplace’s equation to constrain the generation of the potential function of the configuration space of a mobile point-robot. The LBBC provides the Searching algorithm with the capability to escape from flat region, whilst iteration via Four-point Explicit Decoupled Group SOR (4EDGSOR) provides fast computation for solving the Laplace’s equation that represent the potential values of the configuration space.
