Abstract
Numerical method is a technique of obtaining the nearest approximation for the solution of various problems that can be described in the form of derivative equations. Engineering issues cannot be simply overcome using analytical concepts. This study aims to propose a new scheme from an enhanced Euler method for testing the resistor-inductor (RL) circuit equation. For this purpose, the paper proposes the Euler Root Mean Square (ERMS), a modified Euler method with improved accuracy. It will justify that the new scheme can be as accurate as possible in providing the exact solution by applying an average concept of using root mean square. It will focus on this accuracy by comparing the exact solution and actual solution between the new ERMS scheme and a modified Euler known as Euler Arithmetic. This study has demonstrated that the ERMS provided solutions that are similar to the exact solutions at t=0.5. It proves that an enhanced Euler method can be applied in various fields, especially in electrical engineering. In conclusion, the ERMS can be used as an alternative algorithm to solve RL circuit problems.

Abstract
Surface finish is one of the most important quality characteristics in manufacturing industries which influences the performance of mechanical parts. This research is focused on the optimization of machining parameters on surface roughness for parting or cut-off operation for the turning process. In machining operations, achieving desired surface quality features of the machined product are really a challenging job. These quality features are highly correlated and are expected to be influenced directly with the effect of process parameters used. Thus, the inputs of machining parameters such as cutting speed (v), feed rates (f) and depth of cut (d) have been selected and the experimental works were designed using the Response Surface Methodology (RSM) for machining AISI D3 steel. The results revealed that at a minimum cutting speed of 140m/min, a minimum feed rate of 0.01mm/rev and a minimum of depth of cut 1 mm give better surface finish. The study concludes that the surface roughness AISI D3 steel is greatly influenced by feed rate and cutting speed which is proven its reliability to obtain the desired level of surface roughness.

Abstract
As more and more media-based and game-based education (Edu-Game) is released each year to meet the increasing demands of this unique form of learning, the Edu-Game is increasingly developing the primary growing market in the education industry. The future of learning is indeed an educational video game, it has been said to suit the learning style of the new generation better than the previous generation. . This also suggests that the use of programming subjects has also expanded to Edu-Game as well as Classroom programming education has been reported to not be as effective as it used to be. . While several Edu-Game for programming are released today, there is a void that has yet to be occupied, which is a Edu-Game that teaches the language of C++ programming. Furthermore, the concern is the lack of C++ programming language for teaching higher education learners, as C++ has proved to be the most commonly used programming language in the education system in Malaysia. CodeToProtect is a proposed designed video game that will fill the void by providing Malaysia’s higher education learners with C++ programming language and education video game. The game is designed to help students understand the idea of programming by presenting visual representation and gamification to increase student concentration. By designing the game, more students would be able to benefit as C++ is commonly used in Malaysian education, thereby enhancing the overall standard of education programming here in Malaysia.

Casting method was used in this study in order to produce thin film. In this study, MC as a based doped with different weight percentage of AB (4%, 9%, 14%, 19%, 24% and 29%) to produce thin film for further study on polymer electrolytes. Two objectives were done in this study: prepare MC doped AB thin film via casting method and to determine and compare the conductivity of MC and AB with different weight percentage (wt.%) of AB. The result shows that different weight percentage of salt resulting different result of conductivities as ion conductivities is the major part in the battery system. Sample MCAB19 was found to have the maximum ionic conductivity value of 1.42 x 10−7Scm−1 at room temperature. The samples’ conductivity is very low comparing to the commercial used nowadays. However, it is proven that the combination of MC and AB has the prospective to be an alternative to a SPE in the battery.

Published: June 2021

Abstract
This paper presents a method for predicting the evaluation results of learners interacting with a context-aware microlearning system. We use ASUM-DM to guide different data analytics tasks, including applying a genetic algorithm that selects the prediction’s highest weight features. Then, we apply Machine Learning models like Random Forest, Gradient Boosting Tree, Decision Tree, SVM, and Neural Networks to train data and evaluate the context’s effects, either success or failure of the learner’s evaluation. We are interested in finding the model of significant context-influence to the learner’s evaluation results. The Random Forest model provided an accuracy of 94%, which was calculated with the cross-validation technique. Thus, it is possible to conclude that the model can accurately predict the evaluation result and relate it to the learner context. The model result is a useful insight for sending notifications to the learners to improve the learning process. We want to provide recommendations about learner behavior and context and adapt the microlearning content in the future.

Anomaly Detection Algorithm Based on Semi-Supervised Collaborative Strategy
Authors: Shao Mingtian , Gu Naijie 
Published: June 2021

Abstract
This paper analyzes the existing credit card anomaly detection classification algorithms, summarizes the parts that can be improved, and proposes an outlier detection classification algorithm based on the unsupervised algorithm and active learning decision trees. Since the 1990s, machine learning technology has been widely used in the field of credit card fraud detection. Among them, the supervised learning expert system used for classification tends to perform better than the unsupervised learning model. The good performance of supervised learning methods requires high learning costs. The training process is usually serial or partially parallel. Therefore, the computing power, time, and manual labeling cost for learning need to be considered as algorithm selection factors. However, manual labeling usually involves the counter or ATM sending information to the back-end large-value transaction authorization department for manual review, and then the employee judges whether it is an abnormal transaction based on experience. This rigorous process will produce a very large time delay. Combining this feature, this article selects the appropriate unsupervised outlier detection method, selects part of the training data, and uses a small part of the more valuable data for annotation learning. Experiments show that this method can improve the accuracy while saving the time cost of training. Compared with the training time, the added time of classification is negligible.

Published: June 2021

Abstract
With the continuous development of society, the increasing number and size of oil-gas pipelines, how to ensure the safe operation of the pipeline has become a major problem. At the same time, under the premise of defects, it is of great significance to predict the residual strength of pipeline for the safety of pipeline operation. At present, scholars at home and abroad have conducted in-depth studies on the evaluation of residual strength of pipelines, but there are mainly two problems in the research, namely, low evaluation accuracy and inconvenient application of evaluation method. Therefore, based on SVM algorithm, a residual strength prediction model for single-defect pipelines is established from four aspects, including model construction, parameter optimization, node number determination of hidden layers and kernel function optimization. The prediction results are highly feasible and advanced compared with various algorithms and standard methods.
