The research aim to know the effect of note–taking by computer method as amentalactivators in achievement of physics subject for the first intermediate class students.

To investigate from aim of the research the research sample was chosen from the first intermediate class students in Al–mutamyzat secondary school for girls. Which belongs to the general administration for the second karkh education which randomly chosen from (9) schools for distinct female students in Baghdad. Then randomly chosen two sections form three about (80) female students at (66.667%) from total sample it’s about (120) female student in the three sections. The randomly chosen too, section (a) to represent experimental group it’s about (41) female students at (34.167%) and the section (g) represent the control group it’s about (39) female students at (32.5%) from the research society then the experimental and control groups design with apost–test was chosen the two groups have been equalization in the two variables that is (the female students g achievement in physics and mathematics subjects for mid year) and in another variable swhich effect on rocedure of the research. Then the experimental group female students was teaching by using note–taking by computer method as mentalactivators but the control female students was teaching by traditional method for physics subject before that the researcher put the special aim sand the behavior objectives in the light of bloom classification and she makes the teaching plane swhich was exposing them of specialists in physics and its teaching methods to ascertain from their validity for application. Then the esearcher prepared an achievement post-test which kind multiple–hoice with three chosen depend on the physics subjects include (38) items in the light of bloom classification by remember, understanding, and application level. It’s by using half–spilt method and the persone quation the reliability was (0.75) and correct that by using spearman–brown equation (r21) it was (0.85) the experiment was conducted in these condterm of the academic year (2012–2013). The data were statistically processed by using t-test formula for two

Unequal independent samples then the stand by hypothesis was accepted that’s there is statistic significant difference at (0.05) level between two averages for the female students which studied by using note–taking by computer method and for the female student which studied by using the traditional method in achievement for physics subject for the first intermediate class.

Then in the light of the research results the researcher commended the education mainstay and higher teaching mainstay to adoption for the note–taking by computer method to training the physics teacher to use it in their teaching and include it in the decision of the curriculum and the researcher suggested to makes imilar studies in several subjects and the stages of study to know it effect in achievement end another variables.

Securing Text Messages Using Graph Theory and Steganography
...Show More Authors

      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

Text Multilevel Encryption Using New Key Exchange Protocol
...Show More Authors

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

Honeyword Generation Using a Proposed Discrete Salp Swarm Algorithm
...Show More Authors

Honeywords are fake passwords that serve as an accompaniment to the real password, which is called a “sugarword.” The honeyword system is an effective password cracking detection system designed to easily detect password cracking in order to improve the security of hashed passwords. For every user, the password file of the honeyword system will have one real hashed password accompanied by numerous fake hashed passwords. If an intruder steals the password file from the system and successfully cracks the passwords while attempting to log in to users’ accounts, the honeyword system will detect this attempt through the honeychecker. A honeychecker is an auxiliary server that distinguishes the real password from the fake passwords and t

Animal-Based Metaphors as Being a Lingua-Cultural Way in the Field of Football Club Titles: Зооморфная метафора как лингвокультурологический способ в области прозвищ футбольных клубов
...Show More Authors

 

       Metaphor is a linguistic phenomenon related to people's cultures. It is an integral part of cultural heritage. This paper tackles the use of animal-based metaphors in the field of football club titles so as to draw comparisons between those in Russian with their counterparts in Arabic. Names of animals are used to refer to some clubs and teams, where these names or titles reflect animal features such as strength, preying on victims; or animal figures are employed in the club symbols, or due to the similarity of the club shirt to the animal outer shapes in colours. For instance, "an-Nawaris", which means gulls in English, is used to refer to az-Zawraa club du
