The most important results of the study: The emergence of the most important obstacles affecting students' adaptation to e-learning programs, including poor electronic skill, weak communication networks, and political and security instability constitutes frustration. Great in adapting to the requirements of e-learning, the family burdens of those married to them, the difficulty of understanding scientific lessons, the weakness of trust between family members, the magnitude of the scientific material that leads to the frustration of the student, and the state’s lack of interest in providing e-learning techniques. As for the specialization, the study showed the occupation of an obstacle of weakness Communication networks without benefiting from e-learning were ranked first, and with regard to gender, the students ’economic weakness came first among males with an average of (4.33), and fifth among females with an average of (4.32). The magnitude of the scientific material leading to student frustration ranked second among males with an average of (4.32) and the second among females with an average of (4.43), and the complaint came equally among both sexes, which shows us the importance of this obstacle and taking into account the exceptional circumstance, this is what the Ministry of Higher Education and Scientific Research emphasized in taking into account the students ’social conditions. As for the social situation, the student’s weakness of the economic aspect was a major obstacle to the first place among married people and the last rank among singles, and this phenomenon came as a result of the prevalence of the phenomenon of early marriage for both sexes, which is a phenomenon that leads With the youth due to the lack of adaptation as a result of the early burdens that fall on their shoulders as they draw their future, they have a double role to fulfill the requirements of daily life. Also, the obstacle of the enormity of the scientific material that leads to the frustration of the student occupied the third rank among the married and the second among the bachelors, which is a close result and has already appeared to the same degree in As for the rest of the variables, as for the social environment, the obstacle of the state’s lack of interest in providing e-learning technologies came second in both environments, and this is an indication that it is an urgent need for the Ministry of Higher Education to put it among the priorities by providing audio laboratories and other modern science techniques. One of the most important recommendations: is to mobilize all The scientific and skillful capabilities of a faculty member whose role has become an organizer and facilitator of the training process Badly; In order for the new experience to succeed, as for the ministry, it is incumbent upon the ministry to provide appropriate conditions by providing audio laboratories and other modern learning techniques, and coordinating between the Ministry of Higher Education and Communications to support the Western Region by providing electronic reception and broadcasting devices, and holding training courses for faculty members for e-learning and urging them to own Good skill, lightening the momentum of the process article to suit the requirements of the stage.

The future of space communications has evolved towards being cognitive in order to improve energy and spectrum efficiency. Nowadays, near-Earth space satellites for weather, civil defense, and public commercial sectors are rapidly increasing, thereby resulting in congestion. Cognitive digital radio is a form of dynamic wireless communication in which a transceiver can intelligently detect the parts of communication channels that are currently not in use and instantly move into vacant channels while avoiding occupied ones. A challenge for communication between satellites and ground terminals involves calibrating both the time and frequency channels during rapid relative movement. A more dynamic and highly-precise algorithm for enhancing communication between satellites and base station terminals such as deep learning in cognitive radios is proposed that enables significant degree of automation in the space communication networks where spectrum interference is a key issue.

The development of new communication networks to offer innovative services has increased the volume of data. With the introduction of Deep Reinforcement Learning and Service Function Chaining architecture, new research opportunities have emerged to propose solutions to the new challenges. This work proposes a model through computational simulations how these techniques can be applied. The model was evaluated using two variations of the Deep Q-Network algorithm over the CIC-Darknet dataset. Results showed that both variations are a promising mechanism to make the networks more autonomous and intelligent. to demonstrate

Unmanned aerial vehicles (UAVs) will be an integral part of the next generation wireless communication networks. Their adoption in various communication-based applications is expected to improve coverage and spectral efficiency, as compared to traditional ground-based solutions. However, this new degree of freedom that will be included in the network will also add new challenges. In this context, the machine-learning (ML) framework is expected to provide solutions for the various problems that have already been identified when UAVs are used for communication purposes. In this article, we provide a detailed survey of all relevant research works, in which ML techniques have been used on UAV-based communications for improving various design and functional aspects such as channel modeling, resource management, positioning, and security.

Abstract. Pharmacological neuroenhancement, defined as the misuse of prescription drugs, illicit drugs, or alcohol for the purpose of enhancing cognition, mood, or prosocial behavior, is not widespread in Europe – nevertheless, it does occur. Thus far, no drug has been proven as safe and effective for cognitive enhancement in otherwise healthy individuals. European studies have investigated the misuse of prescription and illicit stimulants to increase cognitive performance as well as the use of tranquilizers, alcohol, and cannabis to cope with stress related to work or education. Young people in educational settings report pharmacological neuroenhancement more frequently than those in other settings. Although the regular use of drugs for neuroenhancement is not common in Europe, the irregular and low-dose usage of neuroenhancers might cause adverse reactions. Previous studies have revealed that obtaining adequate amounts of sleep and using successful learning techniques effectively improve mental performance, whereas pharmacological neuroenhancement is associated with ambiguous effects. Therefore, non-substance-related alternatives should be promoted to cope with stressful situations. This paper reviews the recent research on pharmacological neuroenhancement in Europe, develops a clear definition of the substances used, and formulates recommendations for practitioners regarding how to react to requests for neuroenhancement drug prescriptions. We conclude that monitoring the future development of pharmacological neuroenhancement in Europe is important to provide effective preventive measures when required. Furthermore, substance use to cope with stress related to work or education should be studied in depth because it is likely more prevalent and dangerous than direct neuroenhancement.
