R.AkkarElectrical Engineering Department, University of Technology Baghdad, Iraq.Wael A.H.Communications Engineering Department, University of Technology, Baghdad, Iraq.Ibraheem H. M.Al-DosariComputer Communications Department Al-Rafidain University College Baghdad, IraqJournal Article19700101One of the main problems in the oil industrial field is the leakage in<br />transporting pipelines due to its effect on human society , environment, and money loss.<br />Therefore, the bottleneck for most researches in this subject is to minimize false alarm rate<br />(FAR) for the adopted leak detection method. Although some recent methods succeed in<br />classifying the existence or absence of the leak as a binary classification problem. But this<br />paper proposed a novel leak detection technique which predicts the leak location and<br />estimates its size within certain pre-defined ranges. In order to simulate the environmental<br />conditions for real-time operating oil pipeline, accurate simulator known as OLGA<br />program creates the oil physical parameters. Various methods for features extraction are<br />considered such as statistical and wavelet techniques which are implemented to get the<br />features from the fluid simulated waveforms. These features are organized and fed to an<br />ANN classifier trained by PSO algorithm to determine the leak class out of 10 suggested<br />classes. The proposed leak detection technique is used to simulate 18 kilometers belonging<br />to Iraqi crude oil pipelines company operated in Baghdad. The achieved results of the true<br />positive rate (TPR) for the proposed applied method for the leak detection and<br />classification of different leak classes in terms of their positions and magnitudes were<br />about 97%.University of Technology-IraqIRAQI JOURNAL OF COMPUTERS, COMMUNICATIONS, CONTROL AND SYSTEMS ENGINEERING1811-921219120190101HD-sEMG Gestures Recognition by SVM Classifier for Controlling Prosthesis1019167961ENHanadi AbbasJaberComputer Engineering Dept., Basra University, Basra, Iraq.Mofeed TurkyRashidElectrical Engineering Dept., Basra University, Basra, Iraq.Journal Article19700101Electromyography signals (EMG) are an important source to infer<br />motion intention. It has been broadly applied in human-machine interfacing to<br />control the neurorehabilitation devices such as prosthesis and rehabilitation<br />robot. HD-sEMG is a muscle's activity recorded at the delimited area of the<br />skin using 2D array electrode. This strategy permits the analysis of sEMG<br />signals in both temporal and spatial domain. Recent studies display that the<br />spatial distribution of HD-EMG maps improves the recognition of tasks. This<br />work investigates the use of HD-EMG recording to control upper limb<br />prosthesis. The classification of eight hand gestures of able-bodied subjects was<br />developed. Three feature sets were presented in this work. HOG features, time<br />domain features(TD) and the combination of HOG and average intensity<br />features (AIH). Combination of features possibly improved the performance of<br />the classifier. Results show that the combined of intensity features and HOG<br />features achieved higher performance of classifier than other features<br />(Acc=99.37%, P=98.375%, S=97.5%)University of Technology-IraqIRAQI JOURNAL OF COMPUTERS, COMMUNICATIONS, CONTROL AND SYSTEMS ENGINEERING1811-921219120190101Evaluation of Vector-Controlled Asynchronous Machines2027167962ENNihad M.AmeenDepartment of Communication Engineering -University of Technology, Baghdad, Iraq.Ammar S.MuhammedDepartment of Electrical Engineering, University of Technology, Baghdad, Iraq.Journal Article19700101In this paper vector control with variable frequency drive used to<br />apply speed control of a three-phase AC Asynchronous and induction machines.<br />The flux and torque references used to obtain the current components.<br />Proportional-Integral controllers are used to keeping the measured current<br />components at their reference values. The stator voltage references are the<br />output of the PI current controllers. High-performance with the smooth<br />operation is obtained using the proposed method. The differences can be seen in<br />behavior dynamic state. When the motor is rotating at full speed with a full<br />load,it reaches good current waveforms very easily due to the independent PI<br />control of torque and magnitude of flux. In high and sudden variations of the<br />reference input, the direct command is more efficient and less demanding for<br />the equipment. The expressions of the fundamental variables (speed, torque,<br />flux) and equivalent phase circuit of the machine will be reviewed.University of Technology-IraqIRAQI JOURNAL OF COMPUTERS, COMMUNICATIONS, CONTROL AND SYSTEMS ENGINEERING1811-921219120190101Design and development of E-passport scheme using multi encryption biometric information2734167963ENIsraa ShakerTawficProvinces Affairs ,Ministry of Science and Tecghnology, Baghdad, Iraq.Journal Article19700101within the next year, travelers from difference world may be holding<br />a new form of a passport.The electronic passport has been widespread in recent<br />times, all around the world, since the e-passports can save biometric<br />identifiers.To forbidden the illegal entry of passengers into a particular state<br />and stop the use of fake documents, an e-passport is used for more precise<br />identification of a person.The paper used the image of the e-Passport holder as<br />a cover image to hide the fingerprint inside it within the operation of e-Passport<br />design.

Moreover, the DC-DC power converters are the<br />ideal candidates in numerous applications such as electric and hybrid vehicles,<br />fuel cells and others. They have been extensively researched upon over three<br />decades. The control of these converters has been often implemented using<br />PWM techniques and based on discrete components and integrated circuits. In<br />this paper we propose a systematic approach for the control of step down DCDC<br />converters with variable input voltage based on discontinuous control<br />action. We demonstrate that the proposed algorithm achieves robustness to<br />variations of the converter load and the input voltage without additional<br />sensors.University of Technology-IraqIRAQI JOURNAL OF COMPUTERS, COMMUNICATIONS, CONTROL AND SYSTEMS ENGINEERING1811-921219120190101Design of Control System for 4-Switch BLDC Motor Based on Sliding-Mode and Hysteresis Controllers4251167965ENMohammed MoanesEzzaldeanDepartment of Electrical Engineering-University of Technology, Baghdad-IraqQusay S.KadhemDepartment of Electrical Engineering-University of Technology,Baghdad-IraqJournal Article19700101This paper presents a design of a complete dual-loop controller for 4-switch<br />brushless dc motor. In low power, low-cost applications, the 4-switch inverter topology is<br />a felicitous alternative of the ordinary 6-switch inverter. The controller of the 4-switch<br />BLDC motor has to be uncomplicated and can be implemented without the use of<br />expensive hardware to avoid increasing the overall cost of the drive system. Furthermore,<br />the control must be able to deal with the known problems of the 4-switch drive which are<br />speed limitation and high ripple torque. The proposed controller comprises sliding mode<br />speed control and direct current hysteresis control. To investigate the performance of the<br />proposed design, the system is modeled by using Matlab/Simulink, the results are<br />obtained for different working conditions. The propitious results certify the applicability<br />of the proposed controller in low-cost 4-switch BLDC motor drive systems.University of Technology-IraqIRAQI JOURNAL OF COMPUTERS, COMMUNICATIONS, CONTROL AND SYSTEMS ENGINEERING1811-921219120190101Speed Controller of Three Phase Induction Motor Using Sliding Mode Controller5262167966ENFarazdaq R.YaseenControl and System Engineering Department, Unversity of Technology, Baghdad, IraqWalaa H.NasserControl and System Engineering Department, Unversity of Technology, Baghdad, IraqJournal Article19700101A Sliding Mode Control (SMC) with integral surface is employed to control<br />the speed of Three-Phase Induction Motor in this paper. The strategy used is a modified<br />field oriented control to control the IM drive system. The SMC is used to calculate the<br />frequency required for generating three phase voltage of Space vVector Pulse Width<br />Modulation (SVPWM) invertor. When the SMC is used with current controller, the<br />quadratic component of stator current is estimated by the controller. Instead of using<br />current controller, this paper proposed estimating the frequency of stator voltage<br />whereas the slip speed is representing a function of the quadratic current. The simulation<br />results of using the SMC showed that a good dynamic response can be obtained under<br />load disturbances as compared with the classical PI controller; the complete<br />mathematical model of the system is described and simulated in MATLAB/SIMULINK.University of Technology-IraqIRAQI JOURNAL OF COMPUTERS, COMMUNICATIONS, CONTROL AND SYSTEMS ENGINEERING1811-921219120190101Particle Swarm Optimization Based LQ-Servo Controller for Congestion Avoidance6370167967ENSana S.Sabrycollege of engineering, University of information technology and communications, Baghdad, IraqThaker M.Naylcollege of engineering, University of information technology and communications, Baghdad, IraqJournal Article19700101The network congestion is an essential problem that leads to packets<br />losing and performance degradation. Thus, preventing congestion in the<br />network is very important to enhance and improve the quality of service. Active<br />queue management (AQM) is the solution to control congestion in TCP network<br />middle nodes to improve theire performance. We design a linear quadratic<br />(LQ)-servo controller as an AQM applied to TCP network to control congestion<br />and attempt to achieve high quality of service under dynamic network<br />environments. The LQ-servo controller is proposed to provide queue length<br />stabilization with a small delay and faster settling time. The designed controller<br />parameters are tuned by using the particle swarm optimization (PSO) method.<br />The PSO algorithm was fundamentally applied to find the optimal controller<br />parameters Q and R, such that a good output response could be obtained. The PI<br />controller is examined for comparison reasons. The MATLAB simulation result<br />shows that the controller is more effective than the PI in reaching zero steadystate<br />error with better congestion avoidance under the dynamic network<br />environment. Moreover, the proposed controller achieves a smaller delay and<br />faster settling time.University of Technology-IraqIRAQI JOURNAL OF COMPUTERS, COMMUNICATIONS, CONTROL AND SYSTEMS ENGINEERING1811-921219120190101Routing with Energy Threshold for WSN-IoT Based on RPL Protocol7181167968ENSarah AmmarRafeaCollege of Information Eng., Al-Nahrain University, Baghdad, Iraq.Abdulkareem AbdulrahmanKadhimCollege of Engineering., Al-Nahrain University, Baghdad, IraqJournal Article19700101Internet of Things (IoT) enables things to have connectivity through<br />the internet. The number of things is growing fast and has to be uniquely<br />identified through the Internet to communicate with other things. In Wireless<br />Sensor Networks (WSNs) each node can be considered as a thing. WSN node<br />resources are very limited due to the need to communicate using low power and<br />usually through unreliable links. Such limitations need an energy efficient<br />routing protocol. WSN is considered as a type of Low power and Lossy<br />Network (LLN). The routing protocol for low power and lossy network (RPL)<br />is being adopted for LLN and has been standardized to enable connectivity of<br />WSN over IoT. RPL constricted a topology similar to tree topology. Nodes in<br />RPL optimized its path using an objective function (OF). OF depends on<br />different node/link metrics in the optimization process. In this paper, an Energy<br />Threshold RPL (ETRPL) protocol is proposed. ETRPL depends on a new<br />objective function to enhance energy consumption of RPL protocol by taking<br />into account the remaining energy of the preferred parent node. ETRPL is<br />implemented using Cooja simulator. The results show that ETRPL provides an<br />increase in the remaining energy of at least 87.4% for a small area with high<br />number of nodes. ETRPL also performed better with regards to Time Delay,<br />Packet Reception Ratio, and the number of dead nodes in a small area. For a<br />large area, the performance is not encouraging. Thus the proposed ETRPL<br />protocol is useful for IoT networks with relatively small areas.University of Technology-IraqIRAQI JOURNAL OF COMPUTERS, COMMUNICATIONS, CONTROL AND SYSTEMS ENGINEERING1811-921219120190101Smart Autonomous Wheelchair Controlled by Voice Commands-Aided by Tracking System8287167969ENFarah F.AlkhalidControl and Systems Engineering Department/ University of Technology_Baghdad, IRAQBashra KadhimOleiwiControl and Systems Engineering Department/ University of Technology_Baghdad, IRAQJournal Article19700101This study focuses on the design of an autonomous wheelchair based<br />smart driving features for disabled persons.
