Viscoelasticity is a complicated theorem that is generally used in several aspects of material characterization and modeling of polymers, resins, fiber-reinforced composites, bituminous composites, etc. On the other hand, the heterogeneous nature of composites like asphalt concrete and fiber-reinforced polymers has motivated lots of researchers to investigate the mechanical and rheological properties of these materials. This book mainly consists of the theory and application of viscoelastic materials used for construction. It starts with a comprehensible presentation of the theory of linear and nonlinear viscoelasticity. Wherein, the application of viscoelastic equations and principles on constructional viscoelastic composite materials considering time, temperature, loading rate dependency, and heterogeneity of composite substances is highlighted. The principles and equations of the viscoelasticity theorem are presented in several books, but here it is tried to present them more understandable and straightforwardly. This helps in solving real problems of heterogeneous composite materials, especially those which are used in construction. Moreover, the fundamental experiments for characterizing the elastic and viscoelastic properties of fibrous and bituminous composites are introduced and summarized. Then after, some analytical and empirical formulations for deriving the material properties of composites from the properties of the basic constituents are presented. These are followed by numerical simulation techniques using the finite element method to simulate composite materials.
Censorship pervades all aspects of political, social and cultural life in the Islamic Republic of Iran. Faced with strict state control of cultural output, Iranian authors and writers have had to adapt their work to avoid falling foul of the censors. In this pioneering study, Alireza Abiz offers an in-depth, interdisciplinary analysis of how censorship and the political order of Iran have influenced contemporary Persian literature, both in terms of content and tone. As censorship is unrecorded and not officially acknowledged in Iran, the author has examined newspaper records and conducted first-hand interviews with Iranian poets and writers. looking into the ways in which poets and writers attempt to subvert the codes of censorship by using symbolism and figurative language to hide their more controversial messages. A ground-breaking analysis, this book will be vital reading for anyone interested in contemporary cultural politics and literature in Iran.

This book begins by briefly explaining learning automata (LA) models and a recently developed cellular learning automaton (CLA) named wavefront CLA. Analyzing social networks is increasingly important, so as to identify behavioral patterns in interactions among individuals and in the networks’ evolution, and to develop the algorithms required for meaningful analysis. As an emerging artificial intelligence research area, learning automata (LA) has already had a significant impact in many areas of social networks. Here, the research areas related to learning and social networks are addressed from bibliometric and network analysis perspectives. In turn, the second part of the book highlights a range of LA-based applications addressing social network problems, from network sampling, community detection, link prediction, and trust management, to recommender systems and finally influence maximization. Given its scope, the book offers a valuable guide for all researchers whose work involves reinforcement learning, social networks and/or artificial intelligence.

During the past decade, research and development in the area of synthesis and applications of different nanostructured titanium dioxide have become tremendous. This book briefly describes properties, production, modification and applications of nanostructured titanium dioxide focusing in particular on photocatalytic activity. The physicochemical properties of nanostructured titanium dioxide are highlighted and the links between properties and applications are emphasized. The preparation of TiO2 nanomaterials, including nanoparticles, nanorods, nanowires, nanosheets, nanofibers, and nanotubes are primarily categorized by their preparation method (sol-gel and hydrothermal processes). Examples of early applications of nanostructured titanium dioxide in dye-sensitized solar cells, hydrogen production and storage, sensors, rechargeable batteries, electrocatalysis, self-cleaning and antibacterial surfaces and photocatalytic cancer treatment are reviewed. The review of modifications of TiO2 nanomaterials is mainly focused on the research related to the modifications of the optical properties of TiO2 nanomaterials, since many applications of TiO2 nanomaterials are closely related to their optical properties.

Cisterns: Sustainable Development, Architecture and Energy was written on beliefs that based on historical evidence and actual findings, Iran is most probably the country where cisterns, or Aub-anbars in Farsi, were first developed and built. Therefore, it is quite natural for the author to name cisterns in the text Aub-anbars, as it has been called for centuries in this country, the translation of the same name having been used in other countries too. Although in some books, journals and papers published out of Iran by foreign and Iranian scholars, the names Cistern or Water Reservoir have been used. The word Aub-anbar is a compound noun in Farsi; Aub means water and Anbar means tank/reservoir. Putting them together gives the noun Aub-anbarand it should be used as one word.People of the region wanting reserved cool water whether in cities or in different locations across the harsh desert during their travel. Queen Zubeida, the wife of Khalifa Haroon Al-Rasheed in 750 AD built one of these cistern closer to the town of Hiyal in Saudi Arabia so that the Pilgrims? Caravans going to Mecca will have cool, fresh water. This book consists of 11-chapters with full analysis, illustrations and photographs. It makes interesting readings to those interested into vernacular architecture, traditional buildings and creative thinking.

What do the occult sciences, séances with the souls of the dead, and appeals to saintly powers have to do with rationality? Since the late nineteenth century, modernizing intellectuals, religious leaders, and statesmen in Iran have attempted to curtail many such practices as "superstitious," instead encouraging the development of rational religious sensibilities and dispositions. However, far from diminishing the diverse methods through which Iranians engage with the immaterial realm, these rationalizing processes have multiplied the possibilities for metaphysical experimentation. The Iranian Metaphysicals examines these experiments and their transformations over the past century. Drawing on years of ethnographic and archival research, Alireza Doostdar shows that metaphysical experimentation lies at the center of some of the most influential intellectual and religious movements in modern Iran. These forms of exploration have not only produced a plurality of rational orientations toward metaphysical phenomena but have also fundamentally shaped what is understood as orthodox Shi‘i Islam, including the forms of Islamic rationality at the heart of projects for building and sustaining an Islamic Republic. Delving into frequently neglected aspects of Iranian spirituality, politics, and intellectual inquiry, The Iranian Metaphysicals challenges widely held assumptions about Islam, rationality, and the relationship between science and religion.

This book presents intelligent methods like neural, neuro-fuzzy, machine learning, deep learning and metaheuristic methods and their applications in both volcanology and seismology. The complex system of volcanoes and also earthquakes is a big challenge to identify their behavior using available models, which motivates scientists to apply non-model based methods. As there are lots of seismology and volcanology data sets, i.e., the local and global networks, one solution is using intelligent methods in which data-based algorithms are used.
In this paper, a new control strategy that employs a mid-course correction to control the particle size distribution in emulsion polymerization is developed. In this approach, online and infrequent measurements are used to obtain the states of the system at the mid-course of the process. Then an optimization is performed to obtain the optimal trajectory of the input from the mid-course up to the end of the process. For this optimization, a hybrid model is used. This hybrid model consists of the Fokker-Planck particle size distribution model of emulsion polymerization and a data-driven component which corrects the predictions of the Fokker-Planck model based upon the estimated states of the system at the mid-course of the process.
