This study aims at classifying outputs of Reduplication (Total and Partial Reduplication) in Persian, in order to demonstrate the types and processes which lead to the lexicalization of some reduplicated forms and assign them lexical position in lexicography as individual lexical entries. There are distinct phonological, morphological and semantic evidences behind the lexicalization of some types of reduplicated items in Persian. Approximately about 269 totally reduplicated words and 293 partially reduplicated words have been collected and analyzed according to the said morphological, phonological and semantic considerations. Partial and Total Reduplication process is one of the productive... 

In this project sulfur concretes were prepared. The optimum of casting temperature, weight percent of sulfur cement and weight percent of filler were analyzed, so that better corrosion resistance could be found. It is observed, the optimum sulfur is 15% for sulfur concrete samples with 21% sulfur cement; the optimum filler is 10-15% with 18% sulfur cement and finally the optimum filler is 10% for concrete samples with 15% sulfur cement. The casting temperature for concrete with 15-21% sulfur cement is in the interval of 127-150°C could be achieved. By applying the relation between the optimum filler percent and the content of sulfur cement and choosing a suitable temperature for casting... 

In this research, we provide an abstract model for the typography of Persian language (Perso-Arabic script) and study two text corpora based on the Unicode properties of characters and this model. Then we search the corpora for phrases with special properties, based on the abstract model  

This study attempts to describe and analyze Persian speakers’ linguistic knowledge of different types of causative and inchoative constructions within the framework of Lexical Functional Grammar (LFG). In order to do so, different studies on Persian causative alternations within theories other than LFG as well as causative alternations in other languages within LFG are reviewed. Next, different types of causative constructions are categorized conceptually and structurally after they are extracted from Bijankhan corpus (2005). Then they are analyzed syntactically and semantically. In this regard, we represent syntactic and semantic structures based on LFG as a monostratal theory. After that,... 

Semantic classification of words based on unsupervised learning methods is a challenging issue in computational lexical semantics. The goal of this field of study is to recognize the words that are in the same semantic classes; i.e., can have the same set of arguments. Among all word categories, verb is known as one the most important and is assumed as the central part of the sentence in certain linguistic theories such as case grammar and dependency grammar. Based on Levin’s idea, diathesis alternations and the similarity between these alternations are the clues for the semantic classification of verbs. This idea is verified in languages such as English and German with promising results.... 

The purpose of this research is to normalize non-standard persian texts. We proposed a method to transfigure the texts with any non-standard structure into a formal and standard form. One of the major complications of the text normalization is the large variety of non-standard structures, and the fact that these diversities could not be classified in one constructional pattern. Furthermore, the concept of text normalization, in different situations, has multiple different definitions, and any of this settings needs a distinct normalization method. Supervised learning methods are not suitable for normalization due to variety of both standard and non-standard texts as well as the absence of... 

Super cyclone GONU formed on June 2007 has been recognized the strongest tropical cyclone in the North Indian Ocean (NIO). The aim of this study is to numerically simulate the cyclone GONU and its resulting waves in the southern seas of Iran leading to the best parametric model to simulate future occurrence of tropical cyclones (TCs) in the NIO. In this regard, the best track data of the cyclone is extracted from Indian Meteorological Department (IMD). The cyclone GONU wind field is simulated by Young and Sobey, Holland, and Rankin models in order to determine the most appropriate model which is then considered for regenerating cyclonic wind fields over the Makran coastline and the sea of...
