This study draws on the experience from a focus group interviews under the distance learning programme known as Program Pensiswazahan Guru (PPG) organized by the Malaysian Ministry of Education in collaboration with local universities and institutes of education. Its purpose is to uncover students’ perception about the platform used by Internatio
Dynamics of the width and center-of-mass position of a matter wave soliton subject to interaction with arbitrary external potential is analyzed using the collective coordinates approach. It is shown that approximation of the trial function and external potential only in the interaction region of the spatial domain is sufficient for adequate descrip
In this paper we introduce splicing systems with probabilities, i.e., probabilistic splicing systems, and establish basic properties of language families generated by this type of splicing systems. We show that a simple extension of splicing systems with probabilities may increase the computational power of splicing systems with finite components.P
The aims of this study is going to analyze the profile of the population in Sumatra based on the age-groups of the population. The Sumatra Island was divided into ten provinces. The profile analysis is going to use to compare the profile of the proportion of age-groups population among the ten provinces. The test of parallel for the profiles, some
This paper is devoted to the investigation of the existence and stability of strongly localized modes in discrete media in Salerno model by using linear analysis method. The regions of stability and instability are determined. Also the existence of localized modes for different values of parameters is shown numerically by homoclinic orbits intersec
The investigation of the dynamics of nonlinear systems becomes a hot topic in modern science and engineering. One of the most challenging problem is the quantum evolution of nonlinear excitations which has many applications in condensed matter physics, quantum optics, quantum information and other areas of physics. Many different methods were sugge
