        Nezami Ganjavi employs a complex symbolic language in his poetry. His frequent play with words is an attempt to emotionally affect the readers. The present paper is a study of the language Nezami used in his poetry, based on the formalist theory of the deviation from the norms. A prominent aspect of deviation from norms is to use words for meanings other than their usual ones; this has frequently been used in Khamseh. Studying such deviations helps to discover the artistic and poetic techniques of Nazami’s literary creation. Nezami has created his poems by deviation from standard language, and defamiliarization. Notably, the later should be studied regarding the linguistic norms and the time when they were in use. In the construction of Nezami’s poems, deviations of musical, lexical, syntactic, and semantic types play a crucial role. Manuscript profile

        The present study aims to present the model of the application of Islamic ethics in command of the armed forces of the Islamic Republic of Iran. The research method was qualitative - content analysis which used a coding method to classify information obtained through in-depth interviews. The sample consisted of 208 senior military commanders and managers and cadre personnel of the armed forces of the Islamic Republic of Iran, who were chosen with snowball sampling. Accordingly, the model of the application of Islamic ethics in the armed forces of the Islamic Republic of Iran was designed and presented. This model consists of three main categories (the basis of ethical leadership, the pillars of ethical leadership and the performance of ethical leadership). If the armed forces can implement the model with appropriate planning, the armed forces witnessed significant progress in the various ethical areas. Manuscript profile

        4 - A brief, structural approach to Nafsa tul-Masdoor Zeydari
        abolfazl ghanizadeh

        The aim of structuralism in literature is to analyze texts and literary genres, and to examine the external parameters involved in the formation of a literary genre. The structuralists have introduced guidelines to describe writers' works, have introduced aesthetic aspects of works and have compared them with other works. They have also criticized works with a focus on the power of literary figures. The classical literary works require such studies more than contemporary works. As such, this article examines Nafsa tul-Masdoor from a structural perspective, and it analyzes the external parameters (social, political values, intellectual foundations of the writer, the history will) as well as internal parameters (form, technique and content) involved in the formation of this work. The figure of speech in Nafsa tul-Masdoor is technical and the literary studies to date have been limited to description and exposition. I hope this structural work help scholars although the data are limited. Manuscript profile

        In this paper a new control scheme is proposed to ensure stability and performance of the teleoperation systems while a wide range of time delay of transmission line is allowed. For this mean, time delay is estimated and used to predict the plant output. A model reference adaptive controller (MRAC) is designed for the master site using the predicted output of the plant. The proposed control system indicates good stability and force tracking performance. For the slave site, an independent MRAC is designed and it is shown that a good tracking for the position and velocity signals is achieved. Manuscript profile

        Self-healing polymers are categorized as smart materials that are capable of surface protection and prevention of structural failure. Polyurethane/polyurea, as one of the representative coatings, has also attracted attention for industrial applications. Compared with polyurethane, polyurea coating, with a similar formation process, provides higher tensile strength and requires shorter curing time. The working principle of polyurea self-healing mechanisms is to fill cracks by introducing more healing components, which can polymerize and seal damage in the material. Alternatively, it can also be addressed by encouraging continuous chemical reactions, which can form bonds to close gaps between the separated faces of material due to the damage. In this paper, extrinsic and intrinsic mechanisms are reviewed to address the efficiency of the self-healing process. Furthermore, the extrinsic and intrinsic mechanisms have been compared to attain a better understanding of the advantages and limitations of each mechanism. Moreover, formulation optimization and strategic improvement to ensure self-healing within a shorter period of time with acceptable recovery of mechanical strength are also discussed. The choice and ratio of diisocyanates, as well as the choice of chain extender, are believed to have a crucial effect on the acceleration of the self-healing process and enhance self-healing efficiency during the preparation of polyurea coatings.

        The transformation of form in architecture in a historical trajectory has been the result of countless factors that have led to the change of principles and indicators in some situations. The purpose of the present research is to investigate the factors and dimensions of the transformations that occurred in mosques without naves during the Safavid and contemporary periods of Iran through a comparative analysis of the form of Sheikh Lotfollah Mosque in Isfahan and Al-Ghadir Mosque in Tehran. The hypotheses proposed to achieve this goal are that the mosque of Al-Ghadir in Tehran and the mosque of Sheikh Lotfollah in Isfahan are similar to each other in terms of formal structure, and the metamorphosis of the form occurred in the form of some physical and spatial indicators. The current research has investigated the metamorphosis factors that have played a role in the formation of these two works in the visible and hidden layers using descriptive and inductive analysis method. The results of the research indicate that the principles of transformation in the form of Sheikh Lotfollah Mosque have taken place due to the index of spatial geometry through rotation and change of direction and translational movement by structural and physical elements, external walls and connecting internal spaces. that in the Al-Ghadir Mosque of Tehran, which was built in the contemporary period, the principles of transformation have taken place not only by changing the form, but also by ignoring and removing the prominent elements of the mosque, including the dome and the minaret. In addition, the rectangular shape of the space under the dome and the pyramid shape of the dome are also other factors of metamorphosis. Manuscript profile

        This article surveys the fundamental value of digital platforms, such as Instagram and Google. Despite the commutable nature of digital technologies, it is challenging to value digital services, given that the usage is free of charge. Applying the methodology of discrete choice experiments, we estimated the value of digital free goods. For the first time in the literature, we obtained data for the willingness-to-pay and willingness-to-accept, together with socio-economic variables. The customer’s valuation of free digital services is on average, for Google, 4.9m Rial per week and Instagram, 3.27. This paper corroborates that Instagram and Google have an intrinsic value to users, despite the fact that the service of the digital platforms is free of charge. This is the beginning of the valuation of free services such as Shad, Rubika, Zarebeen, etc. in Iran, which has played a significant role in the communication industry since the beginning of the Covid-19 pandemic, and in the discussion of the national information network, the market value of the provider companies will be very important.

        The city is the most important area of human life and the largest cell of civilization, and the study of the impact and impression of this area has a special place. The present article aims to investigate and analyze the impact of the European-style defensive fortifications known as Vauban as an effective component in the shaping and spatial organization of the city of Khoi during the Qajar period. The purpose of this research is to explain and analyze why and how European knowledge of urban planning and defensive architecture penetrated in the city of Khoi during the Qajar period and to examine the architectural plan and structure of this castle-city and its impact on the spatial and physical organization of the primary core of Khoi city. In terms of the nature and method of research, the present research is historical-analytical and the method of data collection is library and text mining of historical documents. The research findings indicate that following the developments resulting from modernity and military technology, Iran's military elites realized the necessity of adapting defense fortifications to the needs of the day, i.e. adapting to firearms, including cannons and artillery. Therefore, they started to build European-style defense fortifications equipped with artillery and called "Vauban", one of the prominent examples of which is the tower and rampart of Khoi city in the Qajar period.
