the relation between bilingualism and translation: a case study of turkish bilingual and persian monolingual translation students
translation studies have become an accepted academic subject and books, journals and doctoral dissertations appear faster than one can read them all (bassnet and lefevere, 1990). but this field also brought with itself so many other issues which needed to be investigated more, in the heart of which, issues like ideology, ethics, culture, bilingualism and multilingualism. it is reported that ove...
Extended Analysis of DES S-boxes
For more than three decades, the Data Encryption Standard (DES) was one the most widely used cryptographic algorithms. It is still the dominating block cipher for banking applications. The DES was designed by IBM, verified by NSA and published by the National Bureau of Standards as a US Federal Information Processing Standard (FIPS) in 1977. The algorithm itself was fully public but the complet...
متن کاملOn a Linear Cryptanalysis of a Family of Modified DES Ciphers with Even Weight S-boxes
We investigate the effect of inserting extra linearity in the Data Encryption Standard (DES) through appropriate singular linear encodings of the output of the individual S-boxes. More specifically, we examine the general situation when the output of each S-box of the DES is precoded separately into a properly constructed copy of the inherent even-weight code of length 4. The study is focused o...
متن کاملInputs and Outputs in Islamic Banking System
Evaluation of performance and productivity is among the fundamental concepts inmanagement. In order to achieve their goals, organizations must evaluate theirperformance. One of the important stages of performance appraisal is evaluation oforganization’s efficiency. Banks, financial and credit institutions are among the mostimportant organizations of every economic system, because every activity...
متن کاملNarrow Sense Linear Cryptanalysis of a Family of Modified DES Ciphers with Even Weight S-boxes
We investigate the effect of inserting extra linearity in the Data Encryption Standard (DES) through appropriate nonsingular linear encodings of the output of the individual S-boxes. More specifically, we examine the general situation when the output of each S-box of the DES is precoded separately into a properly constructed copy of the inherent even-weight code of length 4. The study is focuse...
