Eid Yasser H. Elawady <p class="Abstract"><span lang="EN-US">Chest radiography has a significant clinical utility in the medical imaging diagnosis, as it is one of the most basic examination tools. Pneumonia is a common infection that rapidly affects human lung areas. So, finding an advanced automated method to detect Pneumonia is assigned to be one of the most recent issues, which is still prohibitively expensive to mass adoption, especially in the developing countries. This article presents an innovative approach for distinguishing the residence of pneumonia by embedding computational techniques to chest x-rays images which eliminating the demands for single-image investigation and significantly decrease the total costs. Recent advances in deep learning achieved remarkable results in image classification on different domains; however, its application for Pneumonia diagnosis is still restricted. Hence, the main focus is to provide an investigation that will improve the research in this area, presenting a new proposal to the applications of pre-trained convolutional neural networks (CNNs) as a stage of features extraction to detect this disease. Specifically, we propose to combine deep residual neural networks (ResNets), which extract the hierarchical features from the individual x-ray images with the boosting algorithm to select the salient features, and support vector machine for classification (AdaBoost-SVM). After conducting the performance analysis on the available dataset, we have concluded that the precision of the introduced scheme in Pneumonia classification is superior to the most concurrent approaches, resulting in a great improvement in clinical outcomes. </span></p> 2021-01-12T09:12:58-05:00 Copyright (c) 2021 Yasser H. Elawady Prediction of Interpolants in Zero Diluted Images 2021-02-25T17:54:54-05:00 T. Kishan Rao M. Shankar Lingam Manish Prateek E. G. Rajan <p>This paper provides an algorithmic procedure to predict interpolants of zero diluted images. Given a digital image, one can zero dilute it by right adjoining a column consisting of ‘0s’ to every column except the last column and inserting a row consisting of ‘0s’ below every row except the last row. This yields a new image with a size (2W-1)×(2H-1), where W is the width and H is the height of the original image. Another way of zero diluting an image is by right adjoining a column consisting of ‘0s’ to every column and inserting a row consisting of ‘0s’ below every row. This yields a new image with a size (2W)×(2H), where W is the width and H is the height of the original image. Alternatively, subsampling of an image is carried out by forcing pixel values in the alternate columns and rows to zero. Thus, the size of the subsampled image is reduced to half of the size of the original image. This means 75% of the information in the original image is lost in the subsampled image. On the other hand, zero dilution of an image does not cause loss of information but increases the possibility of predicting more information. The question that arises here is whether it is possible to predict more pixel values, which are called interpolants so that the reconstructed image is an enhanced version of the original image in resolution. In this paper, two novel interpolant prediction techniques, which are reliable and computationally efficient, are discussed. They are (i) interpolant prediction using neighborhood pixel value averaging and (ii) interpolant prediction using extended morphological filtering. These techniques can be applied to predict interpolants in a subsampled image also.</p> 2021-01-12T09:25:15-05:00 Copyright (c) 2021 T. Kishan Rao, M. Shankar Lingam, Manish Prateek, E. G. Rajan EEG Channel Selection Using A Modified Grey Wolf Optimizer 2021-02-25T17:54:53-05:00 Hussien Rezk Hussien El-Sayed M. El-Kenawy Ali I. El-Desouky <p>Consider an increasingly growing field of research, Brain-Computer Interface (BCI) is to form a direct channel of communication between a computer and the brain. However, extracting features of random time-varying EEG signals and their classification is a major challenge that faces current BCI. This paper proposes a modified grey wolf optimizer (MGWO) that can select optimal EEG channels to be used in (BCIs), the way that identifies main features and the immaterial ones from that dataset and the complexity to be removed. This allows (MGWO) to opt for optimal EEG channels as well as helping machine learning classification in its tasks when doing training to the classifier with the dataset. (MGWO), which imitates the grey wolves leadership and hunting manner nature and which consider metaheuristics swarm intelligence algorithms, is an integration with two modification to achieve the balance between exploration and exploitation the first modification applies exponential change for the number of iterations to increase search space accordingly exploitation, the second modification is the crossover operation that is used to increase the diversity of the population and enhance exploitation capability. Experimental results use four different EEG datasets BCI Competition IV- dataset 2a, BCI Competition IV- data set III, BCI Competition II data set III, and EEG Eye State from UCI Machine Learning Repository to evaluate the quality and effectiveness of the (MGWO). A cross-validation method is used to measure the stability of the (MGWO).</p> 2021-01-12T09:25:46-05:00 Copyright (c) 2021 hussien rezk hussien Improving Power Quality and Mitigation of Harmonic Distortion Impact at Photovoltaic Electric Vehicle Charging System 2021-02-25T17:54:53-05:00 Adel Elgammal Curtis Boodoo <p>This article offers a clear and realistic design for an active power filter to increase reliability and power quality of the photovoltaic charging system and a high-penetration electric vehicle distribution system<em>.</em> The MOPSO algorithm is used as the basis for problems with optimization and filter tuning. A typical regular load curve is used to model the warped power grid over a 24-hour cycle to estimate the total harmonic distortion (THD). For structures with high penetration of electric cars, the probability of minimizing THD (for example to five percent) is explored via optimum capacity active shunt filters and shunt capacitors. To maximize general performance of the charging system, the switching systems are re-scheduled. Moreover, to increase the current control accuracy of shunt active filter, the fuzzy logic controller is utilized. The major drawback to new system is that it would have unrestricted billing for entire day to cope with voltage interruption. In MATLAB / SIMULINK, detailed machine setup and control algorithm experiments are simulated. The simulation findings confirm the efficiency and viability of projected shunt active filter to enhance voltage profile and track power performance of photovoltaic charging system.</p> 2021-01-20T04:40:59-05:00 Copyright (c) 2021 Adel Elgammal, Curtis Boodoo E-Notice Board (ENB) for the Faculty Community 2021-02-25T17:54:53-05:00 Kingsley N. Omeje Henry O. Osuagwu Chimezie F. Ugwu <p>This research work developed Electronic Notice Board (ENB) for the faculty community. The purpose is to upgrade the already existing manual method of information dissemination, so as to improve the administrative work of the faculty, and to create an enabling environment for more efficient and friendly means of information delivery. It will improve the rate at which staff and students participate in faculty events and activities. The conventional notice board is one of the oldest methods used in information delivery and announcements to students. Students go to where the notice board is mounted in other to read updates or announcements. Use of wall notice board in every place is a tedious work since it needs to be updated regularly and with correct and right information manually. Few of the problems that necessitated the need for ENB are; inadequate time to read all the relevant information pasted newly on a notice board as a result of tight schedule since the copies are limited. Limited time-lag of newly pasted notice since people mutilate, remove or destroy the paper notices from the board leaving others uninformed. Some of the objectives are to enable individuals to view the update from their various devices from any location. To enable instant update to all users since notice is online. To allow individuals download and store copies of original information intact. Generally, it looks at the existing faculty notice boards, building a system that makes it run by the internet access or by local area network (LAN) so as to increase the rate at which relevant information is being disseminated to the faculty community with no location restriction. The user is kept updated each time the E-Notice Board is updated based on their categories through an SMS alert. This system intends to simplify and improve the University faculties to perform their daily activities since most of the school organs uses computerized system. This research work was designed using Object Oriented Analysis and Design Methodology (OOADM) and implemented using Hypertext Pre-Processor (PHP), Hypertext Markup Language (HTML), Bootstrap, Cascading Style Sheet (CSS) as front-end and My Structural Query Language (MYSQL) database as back-end.</p> 2021-01-20T08:46:25-05:00 Copyright (c) 2021 Kingsley N.

Covid19 has brought many changes to the way people live, social distance and minimal to no contact are our goals. This could have been impossible if we were not surrounded by technology. This Perspective offers a context for the implementation of Remote Technologies, demonstrating the forms in which pandemic preparation, monitoring, research, tracking, and Health Care Technologies are effectively implemented. Our research is focused on providing a solution for handling patients at health facilities with the help of remote technologies keeping in mind the importance of social distancing and minimum to no contact to minimize the spread of the virus. The strategy is to identify the two fronts where contact with a patient is to be made. The first front is the point at which a patient needs to be detected and classified as a potential risk, at this stage the technology needs to identify the patient's symptoms, gather relevant data, and help doctors build a portfolio. The second front is where an admitted patient needs to be monitored and taken care of with regular check-ups, the technology should also take good of the patient’s mental health. The paper proposes a solution to device remote technologies that could prove beneficial in the fight against the deadly coronavirus.</span></p> 2021-01-22T14:22:21-05:00 Copyright (c) 2021 Prakash Kanade, Monis Akhtar, Fortune David Optimal Design, Dynamic Modeling and Analysis of a Hybrid Power System for a Catamarans Boat in Bangladesh 2021-02-02T03:51:17-05:00 Mohammad Abu Abdullah Al Mehedi M.

The country use boats as one of the leading resources of a carrier in its widespread inland waterways. Most of the currently used boats use only diesel for fuel. Appropriate use of renewable energy sources, particularly solar energy with diesel generators, could reduce diesel consumption. In this paper, a typical boat energy requirement was calculated to be 42.10 kWh/day. A boat could be driven by a DC motor using electrical power generated using an onboard PV system, battery, and a small generator. The carrying capacity of the vessel is 20passenger for 8hours a day. The designed system consists of a 10.6 kW PV, 1.6kW rated small gas generator, onboard battery storage consists of 16 batteries, each placed 6V, 333 Ah, and a 48 V DC motor rated 5&nbsp;kW 3000 rpm with a speed controller.

In this work, we have proposed a system for extracting information from several data sources to enrich an ontology in the field of plant pathology. The objective of this work is to develop a knowledge base in the field of plant pathology, by structuring the data present in various data sources accessible mainly through the web. To do this, we first propose a modular development approach of a domain ontology. The construction of the ontology at first uses the text-based construction technique and then, we use the generic architecture of a web data extraction system technique from literature to propose a data extraction system for the enrichment of the different ontology modules of the domain. For each subsystem of our extraction system, we have developed the algorithms to be implemented.</p> 2021-02-02T04:08:05-05:00 Copyright (c) 2021 François Achille Djontu Tajouo, Thierry Noulamo, Jean-Pierre Lienou Big Data Analysis Proposal for Manufacturing Firm 2021-02-15T05:54:01-05:00 Alicia Valdez Griselda Cortes Laura Vazquez Adriana Martinez Gerardo Haces <p>The analysis of large volumes of data is an important activity in manufacturing companies, since they allow improving the decision-making process.

Prolonged exposure of these devices to extreme voltage or frequency makes them susceptible to damage. Since these devices are usually operated round the clock and oftentimes in remote places, it becomes necessary to monitor the quality of the power delivered to them. In this work, we developed a power monitoring system to provide remote access to the supply voltage and frequency of network equipment powered by an uninterrupted power supply system. We develop an instrumentation system to monitor the grid frequency, grid voltage, as well as the UPSS output voltage. We equally present a complete system that processes sensors’ data and make them available to a remote server over a cellular network with a robust email and SMS notification system.
