Data security is an important component of data communication and transmission systems. Its main role is to keep sensitive information safe and integrated from the sender to the receiver. The proposed system aims to secure text messages through two security principles encryption and steganography. The system produced a novel method for encryption using graph theory properties; it formed a graph from a password to generate an encryption key as a weight matrix of that graph and invested the Least Significant Bit (LSB) method for hiding the encrypted message in a colored image within a green component. Practical experiments of (perceptibility, capacity, and robustness) were calculated using similarity measures like PSNR, MSE, and

Wireless Sensor Networks (WSNs) are promoting the spread of the Internet for devices in all areas of
life, which makes it is a promising technology in the future. In the coming days, as attack technologies become
more improved, security will have an important role in WSN. Currently, quantum computers pose a significant
risk to current encryption technologies that work in tandem with intrusion detection systems because it is
difficult to implement quantum properties on sensors due to the resource limitations. In this paper, quantum
computing is used to develop a future-proof, robust, lightweight and resource-conscious approach to sensor
networks. Great emphasis is placed on the concepts of using the BB8

The technological development in the field of information and communication has been accompanied by the emergence of security challenges related to the transmission of information. Encryption is a good solution. An encryption process is one of the traditional methods to protect the plain text, by converting it into inarticulate form. Encryption implemented can be occurred by using some substitute techniques, shifting techniques, or mathematical operations. This paper proposed a method with two branches to encrypt text. The first branch is a new mathematical model to create and exchange keys, the proposed key exchange method is the development of Diffie-Hellman. It is a new mathematical operations model to exchange keys based on prime num

The current research aims to identify the self-regulation of university students, as well as to identify the significance of the difference in self-regulation according to the variable of sex (male-female), specialization (scientific-human), and grade (first-fourth). To achieve the research objectives, the two researchers developed a scale of (28) items about self-regulation According to the theory of (Pandora, 1991). The scale was administered to (500) students from the first and fourth stages of Al -Mustansiriyah University who were selected based on the random stratification method for the 2020/2021 academic year. The results showed that university students have a good level of self-regulation. There are no significant differences in

Writing his own biography is like making his confession in front of the altar of the truth. In The words,Sartre writes his own child life from the view of a philosopher-thinker. He presents his days spent justlike a series of images carrying advices and experiencesto whole the world. The words shows the life of a small orphan who met early with death when he lost his father. Then death becomes as his shadow that goes with him on day and night until the end. The mother of the little Poulou seems like the mirror that reflects the sadness and the melancholy of the dark and gloomy days. The small Poulou becomes his only consolation in misery. The little Jean -Paul lives completely in a literary atmosphere . Because his grandfather Karl Schwe

Current search targeted to:
  1 - Measuring the psychological rebellion among the students of the university.
  2 - Identify the significant differences in the degrees of psychological rebellion among members of the sample according to the variables of sex (male - female), specialty (Science - a human).
      To achieve the objectives of the research chose researcher samples from the community of the first search for statistical analysis, has reached 400 students, and the second sample of the application of the final, has reached (480) students were selected randomly with simple check of equal value, and the researcher building a search tool double think, After the comple

          The she/teacher is considered one of the basics of the educational process for its essential role in education and teaching the kindergarten child, thus  its lack to construct social relations in side the kindergarten environment working in it regarded one of the shortcoming factors she is suffering from which should be manipulated, because it could effect its enthusiasm to work in the kindergarten according to what has mentioned, the researcher presents the following objective:-

• Identifying level of social enhancement for the kindergarten teachers via the test of the following hypothesis:-

The current research aims to measure the level of mental fatigue among the teachers of the University of Baghdad, as well as to measure the significant differences according to the variable of mental fatigue in terms of male and female teachers, specialization (humanitarian, scientific), and title (professor, assistant professor, lecturer). To achieve these current goals, a random sample of (300) teachers from University of Baghdad was selected for the academic year 2019-2020. To measure the mental fatigue, the researcher developed a tool to measure the variable included (56) items. The research revealed that the study sample is mentally tired, the female sample is more mentally tired than males, there are no statistically significant di

الرّهاب، اضطراب نفسيّ واسع الانتشار، وتُشير الدّراسات الحديثة إلى أن نسبة انتشاره تتراوح ما بين (7%-14%) في أغلب المجتمعات، وهو اضطراب مُزمن ومُعطّل للحياة الاجتماعيّة، ولكنّه قابل للعلاج. ويتفق العلماء على أن عدم إدراك المعاق بصريًّا للبيئة المحيطة به، وأركانها يجعل تكّيفه معها محصورًا في إطارٍ ضيق، وبذلك تتبلور مشكلة البحث في الإجابة عن التساؤل الآتي: ما مستوى الرّهاب لدى التلامذة ضعاف البصر في المدارس الاب
