Recently permutation multimedia ciphers were broken in a chosen-plainText scenario. That attack models a very resourceful adversary which may not always be the case. To show insecurity of these ciphers, we present a cipher-Text only attack on speech permutation ciphers. We show inherent redundancies of speech can pave the path for a successful cipher-Text only attack. To that end, regularities of speech are extracted in time and frequency using short time Fourier transform. We show that spectrograms of cipher-Texts are in fact scrambled puzzles. Then, different techniques including estimation, image processing, and graph theory are fused together in order to create and solve these puzzles. Conducted tests show that the proposed method achieves accuracy of 87: 8% and intelligibility of 92: 9%. These scores are 50: 9% and 34: 6%, respectively, higher than scores of previous method. Finally a novel method, based on moving spectrogram distance, is proposed that can give accurate estimation of segment length of the scrambler system.

Shahnameh is the most prominent epic work of Persian language and literature and one of the literary masterpieces of Iran and the world. correction, description, critique and analysis of Shahnameh is one of the fields of study of Persian language and literature researchers. There have been many and valuable efforts in the field of correction of the Shahnameh Text and its description. According to the Shahnameh researchers, the correction of the Shahnameh by Jalal Khaleghi Motlagh, along with the precise recording of other manuscripts in the footnote, is a complete and perfect correction in this filed. In addition to this correction, Shahnameh's photographic prints, scholars' access to other corrections of the Shahnameh, as well as commentaries on the Shahnameh are very helpful in opening up some difficulties. In the light of the foregoing efforts of the Shahnameh researchers, in this study i will indicate the suggestion to record and to give a meaning of the verse from the story of Forud based on San. Joseph's version, which he did not have this verse at the time of correcting and describing the Shahnameh. The author will attempt to review the correctors and commentators opinion about the so called verse and also by referring to manuscripts Text, in-Text evidences of the Shahnameh, out-Text evidences of contemporary and near-Shahnameh Texts and the sequence of verses in the conText of the story propose their suggestion based on manuscripts and consequently the meaning and sense of the verse with the help of recordings and obtained evidences.

In this article, the writers make a distinction between two types of Text, open Text and closed Text. While the latter has a fixed and limited meaning, fixed signifiers and signifieds, with the signs always referring the reader to a fixed world, the former has the potential to be loaded with various meanings. To explicate the two types of Text and the factors that make a Text open, the writers draw on the views of great thinkers such as Rolan Barthes, Wolfgang Izer, Jacques Derrida and Carl Gustav Yung. The purpose of the article is to show how a familiarity with the western interpretations of Hermeneutics can affect our appreciation of Persian literature.

In this paper one of the main forms of Textualization will be represented; little known, in our opinion, first by foreign language specialists (linguists or literary) in Iran and marginalized, even absent, from the educational applications in language and literature courses in the Iranian universities.After an overview of the types of Texts, we will try to develop the idea that concerns us here, namely the study of argumentative type in two ways: firstly the epistemological concept of argumentation and then the organization of the argumentative Text. French: Le Texte argumentatif et la typologie de TextesResume Cet article aura comme but de representer l’une des formes principales de Textualisation, peu connue, a notre avis, d’abord par les specialistes des langues etrangeres (linguiste ou litteraire) en Iran et marginalisee, et meme absente, par consequent, des applications pedagogiques dans les cours de langue et litterature au milieu universitaire iranien.Apres un apercu general de la typologie des Textes, nous avons essaye de mettre au point l’idee qui nous preoccupe ici, a savoir l’etude du type argumentatif sur deux plans: d’abord plan epistemologique de la notion d’argumentation et ensuite plan organisationnel du Texte argumentatif.keywords: Typologie de Textes, Argumentation, Discours Argumentatif, Organisation de Texte, Categories de la Langue

This research is concerned with the "Textualcriticism" in Qajar Period. At first, an introduction to the subject has been presented and then some researches concerning the most important Texts being edited and printed in this period has been introduced and surveyed.The main aim of this research is to introduce and demonstrate the first samplesof the "Textual criticism" in Iran.

One of the most important information security techniques is the hiding of information. Steganography is the art and science of hiding information in the cover of data (in the form of Text, image, video, or audio) such that it does not arise any suspicions, and is difficult or even impossible to discover. This paper presents a method for steganography in the form of Text which uses the methods of Text justifying in typing editors. The method presented in this paper is able to hide information better than some of previous algorithms in this field. This algorithm is resistant to various forms of attack such as visual, structural and statistical attacks. Another important capability of this method is that it can be used to send printed information.

The most important medium through which human beings can form relationships and connections is using different methods such as speaking, writing and sign language. The point that deaf or semi-deaf people are ignored in communities is because of their disability in forming intimate relationships, and also the lack of common training''s according to what is needed in the society. The present study seeks to design a system that receives spoken language as an input and changes it to Farsi sign language after all the necessary normal language analysis is done. The challenges on our way are: a) number of sign language words which are few compared to the words in spoken language and b) the ambiguity and pun normally used in Farsi language. So, common systems architecture could not be applied. Therefore, an architecture is introduced in which Farsi to sign language translation system performance is improved and accuracy and practicality are reinforced through removing pun modules and changing inputs in ways applicable to the world of the deaf applying the related ontology.

Of the most essential tasks should be done in the field of researches on Shahnameh is collecting and analyzing its sporadic verses in other works of Persian old literature. The purpose of such approach is Shahnameh correction.Since there is a 200 years gap between the time Shahnameh was composed (400 AH) up to the time of its earliest version(Florence, 614 AH) and since there are almost some other versions belonging to 7th and 8th centuries AH (less than 10 versions) the Shahnameh corrector must consider every other sources beside existing manuscripts of the book. Among the side sources, there are some sporadic verses of Shahnameh in the Texts of 7th and 8th centuries which have remained as handwritten manuscripts.Taj al-moaser, as a prominent example of above mentioned sources, is the book has been chosen to extract the Shahnameh verses to be compared with their positions in Shahnameh itself.

Jalal-o-din Homaei is a distinguished contemporary researcher and writer who is well-known for numerous works in various fields. A great number of critics and revewers have addressed his life and conditions in their books and articles. The present paper attempts to shed light on the great scholars works from a new perspective.
