A Robust Base-layer Design for Hierarchical IoT Intrusion Detection Using Hybrid Deep Learning
...Show More Authors

The rapid development of Internet of Things (IoT) devices and their increasing numbers have caused a tremendous increase in network traffic and a wider range of cyber-attacks. This growing trend has complicated the detection process for traditional intrusion detection systems and heightened the challenges faced by these devices, such as imbalanced and large training data. This study presents a cohesive methodology of a series of intelligent techniques to prepare clean and balanced data for training the first (core) layer of a robust hierarchical intrusion detection system. The methodology was built by cleaning and compressing the data using an Autoencoder and preparing a strong latent space for balancing using a hybrid method that combines Grey Wolf Optimization (GWO) with Borderline-SMOTE. Particle Swarm Optimization (PSO) was used to select the most important features that provide the greatest amount of information for training the first layer, which was built using deep learning techniques, and linking them in a hybrid manner that combines a Convolutional Neural Network–Long Short-Term Memory (CNN–LSTM) and the Attention mechanism. The proposed model was evaluated using two different types of datasets: the CICIOT2023 dataset, which is characterized by its large size and significant variation in the number of attacks, and the UNSW-NB15 dataset, which is characterized by its simplicity and less imbalance compared to the first dataset, to prepare and generalize the system across multiple environments. The proposed class showed binary classification results with an accuracy of 0.94, an Area Under the Curve (AUC) of 0.93, an optimized F1-score of 0.338, and a Matthews Correlation Coefficient (MCC) of 0.324 at the best threshold on the CICIoT2023 dataset. It also achieved an accuracy of approximately 0.96, an AUC of 0.985, and an MCC of over 0.82 on the UNSW-NB15 dataset. These results confirmed the construction of a strong and resilient layer, preparing the foundation for a robust hierarchical offside detection system.

Discriminant Analysis to Assess Deprivation Index in Iraq
...Show More Authors

The aim of this study is to achieve the best distinguishing function of the variables which have common characteristics to distinguish between the groups in order to identify the situation of the governorates that suffer from the problem of deprivation. This allows the parties concerned and the regulatory authorities to intervene to take corrective measures. The main indicators of the deprivation index included (education, health, infrastructure, housing, protection) were based on 2010 data available in the Central Bureau of Statistics

The Impact of the Internationalization of the Libyan Crisis on the Future of the Political Settlement
...Show More Authors

The internationalization of the Libyan crisis and its accompanying militarization of the conflict have played a vital role in hindering to reach a comprehensive political settlement solution in Libya. The increasing international greediness in the Libyan energy resources and the geopolitical importance of the Libyan State led to the involvement of many international and regional powers in this crisis and transformed the Libyan crisis into “proxy war”.  Moreover, the Turkish direct military intervention in the Libyan crisis is considered as one of the main constraints facing the international and regional efforts to settle the Libyan crisis as a result of the Turkish insistence on its military existence in Libya to preserve i

The Educational Thought of the Chief Justice Badr Al-Din Ibn- Jamaah
...Show More Authors

The ideas and principles formulated by Ibn-Jamaah in the field of education occupy a central place in the historical origins of education for Muslims. These views and principles have an active role in the educational reorganization that the Islamic world aspires to. These ideas have had a great impact on the educational process that had preceded the opinions of Russo, Pestalutzi, Fruel, Herbert, and Dewey. Moreover, we have seen that the Sheikh of Ibn-Jamaah has taken part in formulating the origins of education and leadership.

Stability of Al-Adhaim Earth Dam Under Seismic Actions in Iraq
...Show More Authors
Abstract<p>The investigation of earth dams under significant earthquake loads, such as catastrophic earthquakes, is a critical subject in dynamic evaluation. Damage mitigation and structural performance during an earthquake are crucial considerations for an earthen dam. However, Iraq and its neighbors have experienced frequent earthquake activity, including the 2017 Halabja Earthquake, which may have damaged some existing earth dams, posing a higher risk of severe earthquake-induced damage than a cyclic shock. Therefore, assessing the dam’s safety is crucial for protecting downstream communities and determining the best strategies to prevent slope stability failure in the face of frequent s</p> ...

COMPUTATIONAL ANALYSIS OF THE MIXING ZONE IN THE COMBUSTION CHAMBER OF RAMJET
...Show More Authors

A theoretical analysis of mixing in the secondary combustion chamber of ramjet is presented. Theoretical investigations were initiated to insight into the flow field of the mixing zone of the ramjet combustor and a computer program to calculate axisymmetric, reacting and inert flow was developed. The mathematical model of the mixing zone of ramjet comprises differential equations for: continuity, momentum, stagnation enthalpy, concentration, turbulence energy and its dissipation rate. The simultaneous solution of these equations by means of a finite-difference solution algorithm yields the values of the variable at all internal grid nodes.
The results showed that increasing air mass flow (0.32 to 0.64 kg/s) increases the development o
