Cube Polygon: A New Modified Euler Method to Improve Electric Circuit Efficiency

Euler method is a numerical order process for solving problems with the Ordinary Differential Equation (ODE). It is a fast and easy way. While Euler offers a simple procedure for solving ODEs, problems such as complexity, processing time and accuracy have driven others to use more sophisticated methods. Improvements to the Euler method have attracted much attention resulting in numerous modified Euler methods. This paper proposes Cube Polygon, a modified Euler method with improved accuracy and complexity. In order to demonstrate the accuracy and easy implementation of the proposed method, several examples are presented. Cube Polygon’s performance was compared to Polygon’s scheme and evaluated against exact solutions using SCILAB. Results indicate that not only Cube Polygon has produced solutions that are close to identical solutions for small step sizes, but also for higher step sizes, thus generating more accurate results and decrease complexity. Also known in this paper is the general of the RL circuit due to the ODE problem

How to Cultivate Cyber Security Culture? The Evidences from Literature

Cyber Security Culture (CSC) is a culture that could produce a secure cyber space and could improve the quality of cyber world engagement. Despite many benefits that could be offered by CSC, there is a lack of models and guidelines on how to cultivate this culture. This paper discusses the concept of CSC model in terms of elements that form the model to suggest how CSC could be cultivated. Information Security Culture (ISC) model developed by [1] is used as a framework in discussing the concept of CSC. A literature search also is conducted to find and analyses the most suitable elements for CSC. A new model of CSC was proposed as a result of this study. The findings could provide better understanding of CSC and could be used as baseline to conduct more research on CSC

The Organizational, Professional and Social Condition Perceived by Novice Teachers

Part of the formation of teacher professional identity is caused by the organizational, professional and social condition perceived by novice teachers. An international collaboration project involving seven countries across African and Asian region was set up under the name of Group C African Asian Dialogue Project in order to survey professional identity among teachers in the respected countries. This article focused on the first dimension of the research collaboration endeavor which is to study the organizational, professional and social condition perceived by novice teachers in Bangladesh, Japan, Malaysia, South Africa, Thailand, Uganda and Vietnam. Novice teachers were chosen as the samples of the study as they are in the crucial position in coping with the transition from being considered as preservice teachers to in-service teachers. The challenges arise when they have to accommodate with what they have learnt in the classroom at the university with the challenges and the realities in the school setting to rationalize the significance of professional identities among the novice teachers. The findings of this study are reported based on the percentage response distribution of each items asked in the questionnaire. The results showed that there are some uniformity and variability on how novice teachers perceive their organizational, professional and social condition in the context of their professional identity.Group C: Teacher Professional Development・Work in this project was funded by a grant funded by Universiti Sains Malaysia, Research University Grant under the account number 1001/PGURU/816280. ・Work in this project was supported by The Network of the “Africa-Asia University Dialogue for Educational Development” (A-A Dialogue) ・This work was supported by the Vietnam National University, Hanoi research fund [grant number QG.16.85]

Effects of vegetable oil supplementation on rumen fermentation and microbial population in ruminant: A review

Understanding the nature of ruminant nutrition and digestion is essential to improve feeding management and animal production. Among many approaches, manipulating ruminant nutrition and fermentation through feed supplementation is being practised and researched. Over the last decade, the utilization of vegetable oils in feed formulation and their efects on various aspects of ruminants have been reported by many researchers. It is important to understand the lipid metabolism in ruminants by microorganisms because it afects the quality of ruminant-derived products such as meat and milk. Majority of vegetable oil supplementation could reduce rumen protozoa population in ruminants due to the efects of medium-chain fatty acids (FAs). However, vegetable oil also contains unsaturated FAs that are known to have a negative efect on cellulolytic bacteria which could show inhibitory efects of the fbre digestion. In this paper, the physiology of nutrient digestion of ruminants is described. This paper also provides a current review of studies done on improvement and modifcation of rumen fermentation and microbial population through vegetable oil supplementation

Design and Development of Travel Assist, An App to Support Smart Tourism

Tourism is the third largest contributor to Malaysia’s GDP, worth MYR 86.1 billion in 2019. It is expected that the number of tourists to Malaysia will reach 30 billion in 2020, translated to MYR 100 billion receipts. The Malaysian Smart Tourism 4.0 Initiative strives to unlock the full potential of the tourism industry through enabling technologies of IR 4.0. This work reports the results of an innovation project to support smart tourism in Malaysia. It entails the design and development of Travel Assist, a mobile App for visitors to Malaysia. Travel Assist integrates three common web services: Google Translate, Google Maps, and XE Converter, into one App. It was developed using MIT App Inventor and Adobe Dreamweaver, and suitable for iOS and Android 7.0 (Nougat) devices and above. The App was tested by a group of users to confirm its functionality and feasibility, and the validation results are encouraging. The underlying technology is robust enough to support future innovation ideas and services under the IR 4.0 umbrella

Centroidal Polygon: A New Enhancement of Euler to Improve Accuracy of First Order Non-Linear Ordinary Differential Equation

The Euler method is one of the oldest methods to solve differential equation problems. The Euler method produces the simplest solution. However, although is not computationally expensive, the Euler method is lack of accuracy. To improve the Euler method, the researcher proposed a new scheme for better accuracy. The Euler method equation and the mean method were combined to enhance this method. As the improvement basis, the researcher used the Centroidal mean and the midpoint method or Polygon to improve the Euler method. The combination of the Euler and Centroidal mean is known as Centroidal Polygon (CP) scheme. The CP scheme was used to solve first-order non-linear Ordinary Differential Equations (ODE).  The researcher used SCILAB 6.0 software to solve the equation and the CP scheme was tested in three different step sizes (0.1,0.01, and 0.001). Aside from that, the researcher had compared the CP scheme with previous schemes such as ZulZamri's Polygon (P) scheme, Nurhafizah's Harmoni-Polygon (HP) scheme, and Nooraida's Cube-Polygon (CuP) scheme to ensure that the CP scheme is more accurate than previous research. When the maximum error is calculated by subtracting the scheme and exact solution, the results show that the CP scheme delivers the highest accuracy results in the shortest amount of time. The new enhanced, modified Euler method is useful for other researchers to achieve good accuracy at low computational cost as an alternative to the more computationally expensive methods
