Power consumption is a common problem in wireless sensor networks that many researchers are working on. It represents one of the most serious challenges in wireless sensor networks, as reducing node power consumption can extend the life of the network to a longer time even in the presence of external disturbances. The goal is to reduce power consumption while maintaining the required data throughput in wireless sensor networks. In this thesis, the event-based proportional integral derivative (PID) controller is designed to reduce the power consumption of a wireless sensor network system. Two types of binding are adopted for the event-based PID controller design. The first type is based on the event-based PID controller implementation of a state feedback-controlled system. As for the second type, the PID controlled system has been applied. Initially, the parameters of all controllers were determined by a trial and error approach. Then, in order to improve the performance of the controlled system, the Gray Wolf Optimization (GWO) algorithm was applied to improve the selected control parameters depending on the appropriate performance function. The discussion was attended by the Assistant Head of the Department for Scientific Affairs and Graduate Studies in the department (Prof. Dr. Muhammad Youssef Hassan). On this occasion, we congratulate the student (Najat Muslim Ramadan) and wish her continued success.

Feedback linearization provides applicable design tools for a wide variety of nonlinear systems. This thesis presents an intelligent feedback controller based on the feedback linearization approach to control nonlinear systems. In particular, the nonlinear autoregressive moving average (NARMA-L2) network is trained to reproduce the forward dynamics of the controlled system. Thus, the trained NARMA-L2 network can be immediately integrated into the inverse feedback control (IFC) structure. In order to improve the ability of the NARMA-L2 architecture to approximate nonlinear systems, the NARMA-L2 controller consists of two wavelet neural networks (WNNs). In addition, the RASP1 function was used as the wavelet mother function in the WNN architecture, where this function led to the best control accuracy compared to the more commonly used Mexican Hat, Gaussian, and Morlet functions. To avoid the limitations of the gradient descent (GD) methods, the artificial gorilla force optimization (GTO) algorithm is used to determine the optimal settings for the NARMA-L2 inverse control parameters. In particular, several evaluation tests are used to evaluate the efficacy of WNN-based NARMA-L2 in control accuracy and robustness against external disturbances in each system under study. These tests clearly demonstrated the effectiveness of the control system. Finally, a comparative study showed that the WNN-based NARMA-L2 controller achieved better control results compared to the Multilayer Perceptron (MLP), the NARMA-L2-based RBF, and the PID Controller. The discussion was attended by the Assistant Head of the Department for Administrative Affairs (Prof. Dr. Hazem Ibrahim Ali) and the Assistant Head of the Department for Scientific Affairs and Postgraduate Studies (Prof. Dr. Muhammad Youssef Hassan). On this occasion, we congratulate the student (Taha Shaker Mahmoud) and wish him continued success.

The water management system is nowadays an issue of increasing importance. In this thesis, a safe automated monitoring and control system for dams based on electronic physical systems (CPSs), which is a modern core technology in a complex and heterogeneous cyber world, is proposed. This system consists of three main parts: The physical WSN node, which is the physical world; Communication technologies such as communication protocols; Web-based servers like the world of the Internet. The first part consists of four nodes (NodeMCU8266) as a microcontroller distributed over the dam areas, a Raspberry pi4 as a central server, sensors of water level, temperature and air humidity, sensor of rain and temperature of the dam's water, and three actuators, representing the three gates of the dam. It has become vulnerable to many cyber-attacks. To secure the proposed system, two cyber security algorithms are proposed to detect and prevent cyber attacks. The first one is applied to a physical wireless sensor network (WSN) that adopts telemetry transfer protocol in message queue. The second addresses cyber-attacks on the cloud server side. These algorithms predict DoS attacks on nodes or DoS-HTTP flood attacks on the cloud. Dams are monitored and managed and threats are identified via the dashboard. The proposed system and algorithms were tested by nine case studies. The experimental results showed a high performance of the proposed methods to monitor and manage the dam as well as a high effectiveness of securing the CPS system by detecting and preventing cyber-attacks affecting WSN and cloud servers. The discussion was attended by the Assistant Head of the Department for Administrative Affairs (Prof. Dr. Hazem Ibrahim Ali) and the Assistant Head of the Department for Scientific Affairs and Graduate Studies (Prof. Dr. Muhammad Youssef Hassan). On this occasion, we congratulate the student (Mustafa Yassin Diab) for obtaining the master's degree and we wish him continued success.

The exponential increase in the use of image processing and artificial intelligence in a very large number of applications in many fields makes it a stimulating field for education, business and research. Object detection and analysis is needed in most of these applications. This work is specifically concerned with the human face as an object. For years and still, different face detection methods with different approaches have been competing for better efficiency. Feature-based and image-based methods are the two main methods among these methods. In this work: A relatively extensive review of the methods used in face detection has been undertaken with an overview of their capabilities and limitations. • Two important face detection and analysis methods, one that uses Viola Jones' idea and belongs to the feature-based approach and the other is deep learning on CNN and belongs to the image-based approach, are implemented and analyzed, considering their structure, method of training and work, factors affecting their work, capabilities, limitations, and suitability for detection and analysis. • Ensures working with training as well as testing algorithms Working with algorithms included training as well as testing. The work is carried out on computing platforms (personal computers) with different capabilities, and as a programming environment, PyCharm is used as an integrated development environment with Python as a programming language as well as various libraries that support the construction of algorithms and support the best use of practical computing units. The data sets used in training or tests are taken from internet sources. When choosing the method to use for an application, it is important to consider, among many things, the purposes of the application in terms of accuracy, time, resources, and ability to use the GPU. The door is still open to effective new methods, as well as improving the efficiency of already existing methods. On this occasion, we congratulate the student (Dina Mahdi Abdul-Hussein) and wish her continued success.

The master's thesis of the student Suha Salman Hussein, specialized in Control Engineering, was discussed on Sunday 2/10/2022 at Hall No.9 in the Department of Control and Systems Engineering. Her research was entitled: Integral Sliding Mode Control for Seismic Effects Regulation on Building The Discussion Committee consisted of:

Due to the constant rise in population around the world, the need for multi-storey buildings is increasing. These high-rise buildings are more sensitive to seismic effects than traditional buildings. Therefore, such buildings must be able to resist seismic influences to protect people and the contents of the building. The goal is to reduce the displacement caused by seismic vibrations to an acceptable safe range to make these buildings as safe and comfortable as possible for their inhabitants and with the least possible energy. Three types of controllers are designed to minimize seismic impact: the Sliding Mode Control (SMC) Algorithm, the Integrated Sliding Mode Control (ISMC) Algorithm, and the Integrated Control Algorithm based on the Barrier Function (ISMCbf) to operate the dampers due to their sobriety. Two types of dampers (active and semi-active) were selected and compared under the influence of the same controller. ISMCbf has, in addition to all the known benefits of ISMC, a major advantage that it does not need prior knowledge of the upper limit of turbulence or uncertainty.Moreover, ISMCbf is continuous which means that it does not need any kind of approximation to avoid the phenomenon of high-frequency oscillations caused by the non-continuous part of SMC and ISMC. A semi-active damper (MRD) was chosen to equip the necessary forces under the control of ISMCbf. It was concluded that the use of ISMCbf with an MRD damper can reduce displacement by 86% in the case of a semi-active damper while an active damper has reduced displacement by 54%. Energy was reduced by 56% compared to the active damper. The discussion was attended by the Assistant Head of the Department for Scientific Affairs and Graduate Studies Prof. Dr. Mohammed Yousef Hassan. On this occasion, we congratulate the student Suha Salman Hussein and wish her continued success.
