Shahiduzzaman shahiduzzaman@jkkniu.edu.bd Titya Eng engtitya@outlook.com Md. Noor Jamal noorjamal97531@gmail.com <p>Many researchers have already shown that only user-based or content-based features are not enough to detect rumor in social media and for better prediction we need to consider both. In our research, we argue that the word embedding feature and sentiment score with subjectivity can also play a vital role in this detection task. Moreover, to detect the rumor at a very early stage and debunk it we may need to make the detection framework portable to legitimate users. This critical situation demands a secure implementation of rumor detection framework so that the user information used for training the prediction model can be protected from unauthorized access. In our experiment, we have also found that besides SVM, Logistic Regression and Random Forest algorithms, Artificial Neural Network and k-Nearest Neighbor can be used for rumor detection purpose where Artificial Neural Network and Random Forest outperformed (more than 90%) among all these algorithms in terms of accuracy. Other three algorithms also performed well with 80% or more accuracy level. To establish the robustness and efficiency of our proposed rumor detection mechanism, Precision, Recall, F1 Score, 10-fold Cross Validation, MCC, Confusion Matrix performance measures are used.</p> 2020-07-01T16:39:16-04:00 Copyright (c) 2020 Md Rashed Ibn Nawab, Kazi Md.

O. Okelola mookelola@lautech.edu.ng <p>The effect of the Power Quality events can be devastating if not properly managed. To manage such PQ events effective detection and classification techniques must be developed. There are various mathematical models that can be used in the detection and classification of the events which could vary from Dip, Swell, Interruption, and Harmonic distortion. The paper is based on the classification of Voltage Dip, Voltage Swell and Voltage Interruption using the STFT as the method of the detection of the triggering point and using such synthetic signal to train the Naïve Bayes classifier to develop a classifier that is capable of classifying waveform signals that has such disturbances in them.</p> 2020-07-15T00:00:00-04:00 Copyright (c) 2020 Oluwaseun Elijah Adegbite, M.

Alagbe gaalagbe@lautech.edu.ng <p>&nbsp;The effect of rain in the design of satellite and terrestrial microwave radio links is of interest to Engineers and Scientists. It is good to have a reliable design that guarantees high level of accuracy of the rain rate distribution from the lowest rain rate value to the highest. The present work proposes a model that expresses rain rate as a function of alpha and beta obtained at 0.01% of time. When tested, the results obtained with the measurement perform well for the stations considered at a rain rated between 5mm/h to 200mm/h. Thus, , the empirical models that were obtained through them could be a useful tool for the radio design engineers for high rain rate areas.</p> 2020-07-17T05:03:07-04:00 Copyright (c) 2020 Y. K.

Toukir Ahmed toukirahmedreal@gmail.com Md. Rayhanul Masud r.masudsaom@gmail.com Abdullah Al Mamun kamrul1203@gmail.com <p>Nowadays, women worldwide are affected greatly by Breast cancer. The consequences of the disease and the number of affected are so alarming that it requires immediate attention. Prediction of the disease is the primary and most significant route to prevention of it. This study aims to have a comparison among multiple machine learning based classifiers for breast cancer risk stratification using resonance-frequency electrical impedance spectroscopy. Five machine learning based classifiers namely- Naïve Bayes, Multilayer perceptron, J48, Bagging and Random Forest were applied to the dataset and a comparison was made based on different performance metrics. The study demonstrated that Random Forest classifier performed slightly better than the others in both splitting and folding of the dataset.</p> 2020-07-18T13:27:22-04:00 Copyright (c) 2020 Md.

The power system including synchronous machine, transmission network, and HVDC is based on the concepts of stability mode. In addition, various techniques to reduce the simulation time are systematically applied. The proposed method helps us to access the transient stability of the system with MTDC in the much simpler way. The verification of the methods is tested on 20 generators in an IEEE 118-bus system under various cases.</p> 2020-07-20T12:15:49-04:00 Copyright (c) 2020 Prechanon Kumkratug https://www.ejece.org/index.php/ejece/article/view/225 Toward Palmprint Recognition Methodology Based Machine Learning Techniques 2020-07-20T12:22:10-04:00 M. M. Ata mmaher844@yahoo.com K. M. Elgamily khaledelgamily93@gmail.com M. A. Mohamed mazim12@gmail.com <p>The presented paper proposes an algorithm for palmprint recognition using seven different machine learning algorithms. First of all, we have proposed a region of interest (ROI) extraction methodology which is a two key points technique. Secondly, we have performed some image enhancement techniques such as edge detection and morphological operations in order to make the ROI image more suitable for the Hough transform. In addition, we have applied the Hough transform in order to extract all the possible principle lines on the ROI images. We have extracted the most salient morphological features of those lines; slope and length. Furthermore, we have applied the invariant moments algorithm in order to produce 7 appropriate hues of interest. Finally, after performing a complete hybrid feature vectors, we have applied different machine learning algorithms in order to recognize palmprints effectively. Recognition accuracy have been tested by calculating precision, sensitivity, specificity, accuracy, dice, Jaccard coefficients, correlation coefficients, and training time. Seven different supervised machine learning algorithms have been implemented and utilized. The effect of forming the proposed hybrid feature vectors between Hough transform and Invariant moment have been utilized and tested. Experimental results show that the feed forward neural network with back propagation has achieved about 99.99% recognition accuracy among all tested machine learning techniques.</p> 2020-07-20T12:22:10-04:00 Copyright (c) 2020 M.

The framework uses a rich set of past observations and geometric pattern description and then applies a CBR to formulate the forward problem, Inverse Problem formulation is then applied to identify a set of parameters that can statistically be associated with the occurrence of the observed patterns.</p> <p>This research work presents a formative strategy aimed to determine the causes of behaviour, rather than predict future time series points which brings a novel perspective to the problem of asset bubbles predictability, and a deviation from the existing research trend. The results depict the stock dynamics and statistical fluctuating evidence associated with the envisaged bubble problem.</p> 2020-07-21T06:59:43-04:00 Copyright (c) 2020 Francis Ekpenyong, Georgios Samakovitis, Stelios Kapetanakis, Miltos Petridis https://www.ejece.org/index.php/ejece/article/view/231 Data Mining and Data Analytics for Analysing Customer Churn Rate 2020-07-30T03:33:24-04:00 Sharan Kumar Paratala Rajagopal prsharankumar@gmail.com <p>This research paper describes how to determine the various factors impacting the customers churn rate in telecom industry.

Information and communication technology (ICT) has changed the methods of carrying out activities in different areas of human endeavours. As a result of the world rapidly adopting digital media and information, the roles of ICT in assuring quality education is becoming important and the importance is expected to continue growing.&nbsp; In this paper, the effectiveness of adopting ICT as a tool for Teaching/Learning Processes and academic performance was investigated and issues militating against integration of ICT were reviewed. A total of 90 questionnaires were administered to respondents who were students selected randomly from three polytechnics in Nigeria. The selected students were classified into experimental group (learning using ICT) and control group (learning without ICT).&nbsp; Interviews were also employed for selected lecturers. The results show that the use of ICT as a tool for learning has improved the learning outcome of the selected students and the use of ICT for teaching has made teaching very interesting to students with consequential increase in performance of students. Integration of ICT into Teaching and Learning is considered to be a necessary issue for students, educators and education administrators to assure better understandings and effective teachings.</p> 2020-07-31T04:18:13-04:00 Copyright (c) 2020 GANIYU ABIODUN SALIHU, NURA SIDI UMAR https://www.ejece.org/index.php/ejece/article/view/232 Three-Phase Distribution System Load Flow Analysis Using Sequence Components 2020-08-04T03:42:07-04:00 Rudy Gianto rudy.gianto@ee.untan.ac.id <p>Electric power distribution system are usually unbalance. Therefore, a power flow method that can handle the three-phase configuration of the power system is needed so that the system planning and operation can properly be carried out. In the case of three-phase distribution system power flow analysis, for each system bus (except for substation bus), the voltage magnitude and angle of the three phases must be calculated. These calculations are carried out under certain loading conditions. After these voltages have been calculated, the electric power flows and losses in the distribution lines, and the substation power can also be determined. This paper proposes a new technique for three-phase distribution system power flow analysis using sequence components. The new formulation for the power flow problem in terms of sequence components is also proposed and developed in this paper. The application of sequence components has the advantage that the size of the problem can effectively be reduced, and solution to the power flow problem will be easier to find. Case study using a representative distribution test system confirms the validity of the proposed method where comparative studies between the proposed (i.e. sequence components based) method and the phase components based method are carried out.</p> 2020-08-04T03:42:07-04:00 Copyright (c) 2020 Rudy Gianto
