Comparison New Algorithm Modified Euler Based on Harmonic-Polygon Approach for Solving Ordinary Differential Equation

There are many benefits to improve Euler scheme for solving the Ordinary Differential Equation problems. Among the benefits are simple implementation and low-cost computation. However, the problem of accuracy in the Euler scheme persuades scholar to use the complex method. Therefore, the main purpose of this research is to show the development of a new modified Euler scheme that improves the accuracy of the Polygon scheme in various step sizes. The implementation of the new scheme is by using the Polygon scheme and then Harmonic mean concept that is called the Harmonic-Polygon scheme. This Harmonic-Polygon scheme can provide new advantages more than the Euler scheme could offer by solving Ordinary Differential Equation problem. Four set of problems are solved via Harmonic-Polygon. Findings showed that new scheme or Harmonic-Polygon scheme can produced much better accuracy result

Statistical Validation of ACO-KNN Algorithm for Sentiment Analysis

This research paper aims to propose a hybrid of ant colony optimization (ACO) and k-nearest neighbour (KNN) algorithms as feature selections for selecting and choosing relevant features from customer review datasets. Information gain (IG), genetic algorithm (GA), and rough set attribute reduction (RSAR) were used as baseline algorithms in a performance comparison with the proposed algorithm. This paper will also discuss the significance test, which was used to evaluate the performance differences between the ACO-KNN, the IG-GA, and the IG-RSAR algorithms. The dependency relation algorithm was used to identify actual features commented by customers by linking the dependency relation between product feature and sentiment words in customers sentences. This study evaluated the performance of the ACOKNN algorithm using precision, recall, and F-score, which was validated using the parametric statistical significance tests. The evaluation process has statistically proven that this ACO-KNN algorithm has been significantly improved compared to the baseline algorithms. In addition, the experimental results have proven that the ACO-KNN can be used as a feature selection technique in sentiment analysis to obtain quality, optimal feature subset that can represent the actual data in customer review data

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

Kertas kerja ini membincangkan dengan terperinci kaedah aruhan berasaskan atribut yang merupakan satu kaedah perlombongan data. Pelbagai jenis pengetahuan boleh diperoleh melalui kaedah ini antaranya petua pengelasan, petua ciri, petua pengelasan kuantitatif, petua ciri kuantitatif dan sebagainya. Konsep pengitlakan dan ringkasan merupakan perkara asas dalam melaksanakan kaedah ini. Pengitlakan data dilaksanakan ke atas satu set data yang relevan dengan cara penghapusan atribut, pohon konsep menaik, mengawal proses pengitlakan dengan menetapkan nilai ambang bagi atribut, pembilang perambatan dan nilai fungsi jumlah yang lain. Dua algoritma telah dibina iaitu algoritma kaedah aruhan berasaskan atribut dan algoritma arahan bahasa pertanyaan piawai. Algoritma arahan bahasa pertanyaan piawai bertindak sebagai perantaraan dengan pangkalan data dalam melaksanakan segala arahan bahasa pertanyaan piawai dengan pangkalan data hubungan. Kedua-dua algoritma ini saling berkaitan dalam melaksanakan kaedah aruhan berasaskan atribut yang berorientasikan bahasa pertanyaan piawai. Satu pangkalan data hubungan telah direka bentuk dan dibangunkan untuk menyimpan data pelajar siswazah Fakulti Teknologi dan Sains Maklumat, UKM.

Peraturan interaksi peristiwa komunikatif wawancara dalam akhbar

Peristiwa komunikatif wawancara merupakan suatu peristiwa dua hala yang bersifat interaktif. Dalam peristiwa komunikatif wawancara, pola komunikasi yang diujarkan melalui lakuan bahasa tertentu memberi makna mengikut maksud ujaran daripada pemeran. Komunikasi berkesan dapat mengungkap persoalan siapa, bila, bagaimana, dan apa yang dapat menjelaskan segala keraguan dalam sesuatu pola komunikasi. Ini secara tidak langsung menyentuh kepada penelitian terhadap komponen dalam peraturan interaksi. Justeru, persoalan tentang etiket bahasa perlu diberi penekanan, kerana etiket bahasa memberi perhatian kepada cara-cara bahasa diungkapkan, berteraskan peraturan sosial dan budaya komuniti penuturnya. Objektif kajian ini adalah untuk menghuraikan dan menjelaskan peraturan interaksi melalui pola komunikasi yang diujarkan oleh pemeran dalam peristiwa komunikatif. Tumpuan kajian adalah terhadap wawancara dalam akhbar Mingguan Malaysia dan Utusan Malaysia dengan memberi penelitian terhadap peraturan interaksi yang terdapat dalam peristiwa komunikatif wawancara akhbar. Analisis data dilakukan dengan mengikut pendekatan etnografi komunikasi, dengan memberi tumpuan hanya kepada satu komponen, iaitu komponen norma interaksi. Berdasarkan kajian peristiwa komunikatif wawancara dalam akhbar ini didapati peraturan interaksi melalui penggunaan bahasa lisan dalam suasana formal dapat menyumbang kepada keberkesanan komunikasi dalam suatu hubungan sosial yang diseimbangkan dengan pemahaman terhadap latar budaya pemeran. Ini menjelaskan bahawa etiket bahasa amat dititiberatkan dalam mencapai matlamat suatu perbincangan yang interaktif. Kebijaksanaan pemeran dalam mematuhi peraturan interaksi yang menjadi nilai tradisi suatu komuniti dapat dimanfaatkan untuk memastikan komunikasi berkesan dicapai. Bahkan dalam suatu perbincangan interaktif kematangan setiap pemeran memberi hujah dapat dinilai daripada kemampuan pemeran memahami budaya yang melatari komuniti tertentu

Android application system, keep the distance

While physical distancing is crucial to prevent COVID-19 infection, it is difficult to estimate a safe distance, and sometimes, people tends to be negligent in adopting the new norm. Keep The Distance application system is an Android-based system developed for addressing the difficulty of maintaining a safe physical distancing by giving a warning notification to the users if they are not within a safe distance. KTD application is designed to detect a user's current location using Global Positioning System (GPS), calculate and compare the distance between users to ensure they are at the safe distance of 1 metre. A notification message would be pop-up as an alert if users failed to keep a safe distance. This system will stop if the users turn off the GPS signal. The development of the KTD application adopts the Rapid Application Development approach. The requirements of the KTD are defined through an interview with a teacher from SMK Bandar Tasik Puteri. The KTD application is then built using Android Studio using the Java programming language, and Google Firebase is used as a database to store user's location. The testing for developed KTD is conducted with the teachers from the same school location. The KTD application helps users maintain a safe distance of 1 meter when they detect other nearby users. Moreover, the KTD application can increase users' awareness regarding safe physical distancing as alerts will be given if they failed to do so
