Published: May 2020

Abstract
This research presents the design of a smart digital bidirectional visitor counter (SDBVC). The million religious visits especially in Iraq increased the need for accurate smart counting systems for human to count the largest gathering of people in one place. The major focus is on counting huge number of humans enter one place from multiple entrance gates. The central processing unit (CPU) receives all the data from these gates and finally makes the studies about the overall human number, men number, women number, the period of the day that this number reach the highest and smallest number and etc. The proposed project hardware contains multiple Wi-Fi based Arduino microcontrollers (like Node-MCU Arduino): one Arduino in each gate which is called transmitter and one in CPU which is called receiver, multi ultrasonic sensors for each transmitter placed on the entrance gates (men gates data separated from women gates data). ThingSpeak.com is used to save the large recorded data for long time for example many days and give results and records about the number as Arba’een Pilgrimage for Imam Hussein shrine in Iraq. The proposed system gives accurate results on the number of entered and exit people to and from one place.

Authors: Al-Kadhimi Aymen M 
Published: May 2020

Abstract
Cellular network planning is an essential stage that precedes implementation phase. The planning performance is widely dependent on the terrestrial features of the environment where a network is planned to be implemented in. This work involves the cellular planning of three networks applied in two cities, namely Baghdad and Shaqlawa, with different terrains. Two networks are planned in a flat terrain (Baghdad city) using universal mobile telecommunications system (UMTS) and long term evolution (LTE) technologies and one network is designed in a hilly terrain (Shaqlawa city) utilizing UMTS technology. In this study, several calculation themes are applied to evaluate the performance of the proposed planning such as coverage, power level, carrier to interference ratio, best server and elevation calculations. Also, some clients and points are positioned across networks to measure power levels, interference and coverage at different locations more precisely. The measurements show that the UMTS networks cover an area of 63.62 km2 compared with 81 km2 coverage area in the LTE network with different quality of service graduating from quadrature amplitude modulation (QAM16) and quadrature phase shift keying (QPSK) to voice services. In addition, comparisons between the networks are discussed and enhancement suggestions are presented in this paper.

Published: May 2020

Abstract
Localization schemes are considered very important issue for wireless networks. Today, positioning information takes big space from current research or study. In other words, localization approaches are one of the most significant works which support the creation of new innovations, services, applications and business models in the area of the most system or networks. Different methods, wireless technologies and systems were suggested in the literature to provide sea localization services to enhance the services provided to users. There is, however, a lack of an update survey paper which integrates some of the precise and accurate localization systems recently proposed. In this paper, we intend to conduct a survey of various techniques of localization in sea based on different technologies and systems that was mentioned in the literature. The paper focuses primarily on localization systems from new vision. The current systems introduced in the literature are highlighted and classified in new categories. By comparison to the current surveys, different systems are also previewed from the perspective of their technologies they used. Instead of these classifications, we are proposing a new category for the localization systems and we are also addressing remaining challenges to accurate localization.

Authors: Yas Ruwaida M , Hashem Soukaena H 
Published: May 2020

Abstract
Duo to limited energy of the sensor nodes which forming the wireless sensor network (WSN), and almost deployed in harsh environment, therefore it is very important to minimize the consumption of the sensor node’s energy. For this reasons designing an energy efficient clustering and scheduling of sensor nodes considered the most efficient methods for extending the WSN’s lifetime. In this paper, we have proposed Genetic algorithm based methods for clustering and scheduling. The proposed methods have two stages; in the first stage GA is used for cluster formation where the chromosome is represented by using the sensor node’s position. While in the second stage GA is used for selecting a minimum number of nodes while maintaining the full coverage and the connectivity of the selected nodes. The simulation result shows that the proposed algorithm (AGA) is more efficient than the existent algorithms in terms of number of first node die per round, number of a live nodes, and energy consumption.

Published: May 2020

Abstract
The past four decades have witnessed a rapid and tremendous development in information and communication technologies (ICT), which has led to development in various theoretical and practical fields. In addition, technological diffusion has become a prominent feature in developed countries, which made most developing countries seek to own it because it is the backbone and the main pillar of its development and prosperity. Although Iraq is a country with diverse and enormous resources and a dominant geographical position that makes it at the forefront of the regional and global economy, it still suffers from crises and stagnation due to regional and global conflicts as a battlefield, as well as successive mismanagement and lack of technological awareness in simulating the rapid development of ICT with modern and high technology. In this paper, we will come to learn in brief about the Information and Communication Technology (ICT) and its role in community development will be briefly identified. We also look at the general technological diffusion index by analysing its main and sub-indicators to the Arab countries group, and then we focus on the main obstacles and challenges facing it in Iraq. Last but not least, we will try to lay the scientific foundations according to modern ICT indicators to overcome and defuse those challenges, and finally we have made suggestions and recommendations that contribute to the achievement of the goal that we aspire for throughout this research.

Authors: Kadhum A A , Al-Libawy H , Hussein E A 
Published: May 2020

AbstractIn developed countries, the number of elderly people living alone is continuously increasing. These people are more vulnerable to serious health issues, such as falling down. A sensor-based system, augmented to mobile phones, can provide a much-needed prediction to the falls, where injuries and fracture possibilities can be significantly decreased. The purpose of this study is to develop a fall recognition system based on smartphone inertial sensors, which is a combination of accelerometer and gyroscope. The system can distinguish between falls and other activity daily livings (ADLs). The data output from the inertial sensor have been used by two different classifiers; artificial neural network (ANN) and support vector machine (SVM), where the objective is to find an accurate falling classifier using smartphone inertial sensors. Results show that SVM based classifier offers an accuracy of 99.27%, which outperforms the state of the art results that use smartphone data.

Published: May 2020

Abstract
Images nowadays are an integral part of our lives, whether in scientific applications or social networks and where there is an image, the concept of image blurring may occur. Blurred is a major cause of image degradation and reduces image quality. Blur occurs due to air noise as well as incorrect camera setup. Along with the blur effects, the noise also spoils the captured image. Deblurring is the operation for removing blur or noise and restoring the underlying high-quality image. Blur can be different types like Motion Blur, Gaussian Blur, and Average Blur.

Published: May 2020

Abstract
Face recognition (FR) system is an essential part of a biometric security system, which runs faster than other security methods and done remotely. One of the most important techniques that used in FR is the convolutional neural network (CNN). Traditionally, the choice of the CNN architecture is achieved by experimental trails. In this paper, a new approach is proposed to build a mathematical model that helps to select a proper architecture. This model is built from the experimental results by applying different architectures on the well-known dataset (Vggface2). By changing the class number, image number and convolutional layer number, where the accuracy of each case is recorded. Finally, the proposed model is evaluated on the sets of datasets (Essex. FEI, Caltech), where the accuracies of (99.13, 98.51, 97.78) respectively, are achieved. The evaluation results proved that the proposed model is an efficient for many types of small and middle scale dataset.

Authors: Denisova L A , Karabtsov R D , Meshcheryakov V A , Shirokov I V 
Published: May 2020

Abstract
The paper discusses the optimization of a pulsed automatic control system (ACS) with constant parameters, which is used to control non-stationary objects. We obtained the dependences of the integral quality criterion on perturbations acting on the control object. The sensitivity of the ACS was studied by simulation using MATLAB / Simulink. The system was optimized based on the criterion constructed taking into account sensitivity to parameter variations. It is shown that the synthesis of the ACS insensitive to changes in characteristics is advisable only if the deviations of the parameters are small. In this case, the quality of automatic control will improve.

Published: May 2020

Abstract
The subject of the study is a system for collecting and processing biophysical signals for controlling anthropomorphic prostheses. As a result of the work, structural and electrical circuits for measuring biophysical signals, processing and filtering schemes were proposed, and the necessary filters were calculated. Designed filters allow you to get rid of noise caused by artifacts of movements and your own signal instability, and can be used to design a system for collecting and processing electromyography signals. In conjunction with a digital filtering system and further processing, it is possible to adequately determine the presence of muscle contractions. The resulting system is small-sized and in combination with the software part of signal processing will allow you to determine key signal patterns and control anthropomorphic prostheses.

Published: May 2020

Abstract
This paper is devoted to the mathematical and computer simulation of multi-parameter technological systems. The method and algorithm can easily be used in spline-frame simulation of the systems. Simulation is based on experimental data and achieved by the variation of one-dimensional spline approximations. A set of variable one-dimensional cubic spline-frames generate the model of hyper-surface, which is a model of the process. Each of the spline-frames is the image of a section of input parameters area. Software realization is based on the single algorithm that is used repeatedly. The problem of building some model of hyper-surface is based on empirical irregular 0-dimensional frame. We consider the problem as an inverse problem of modeling. The method has been used in investigation some technological conditions of thread seams for sewing industry. We investigated the durability and harshness of the seam. Geometric models and parameter valuations were generated by special software. The equations and diagrams described our experiments with sufficient exactness and there were used for researching the process. The model together with software HYPER-DESCENT may be applied for simulation multi-parametrical systems or technological processes of light industry.

Published: May 2020

Abstract
In recent years, the construction of churches and temples has been rapidly developed, so the need for design and support for such constructions arose. A new department called “Temple architecture” even appeared at MArchI (Moscow Architectural Institute). The article considers a method for geometric construction of the surface of such objects as the dome of temples and churches from the parts of Dupin cyclides. As a result, two variants of domes made from the compartments of the Dupin cyclide were proposed. Based on the theoretical research, it becomes clear that there can be more design options, and if we use a special case of cyclides for construction - compartments of rotating cones - then many times more.
