Esfahan, Iran

Isfahan University of Art is a public University in Isfahan, Iran. It operated under the name of "Farabi University" before 1978, then it became a campus of the University of Art . It was separated and became independent in 1999. The university owns some of the greatest houses in Isfahan, mostly of the Safavid period. The university's buildings are spread out over the city, most of which are old historics sites such as David House, Martha Peters House, Haratian House, Sookiaas House, Haghighi House, France school and Ayyoubi and Melal House.

Archaeological excavations in western Iran have recently revealed a significant Luristan Bronzes collection from Sangtarashan archaeological site. The site and its bronze collection are dated to Iron Age II/III of western Iran (10th-7th century BC) according to archaeological research. Alloy composition, microstructure and manufacturing technique of some sheet metal vessels are determined to reveal metallurgical processes in western Iran in the first millennium BC. Experimental analyses were carried out using Scanning Electron Microscopy-Energy Dispersive X-ray Spectroscopy and Optical Microscopy/Metallography methods. The results allowed reconstructing the manufacturing process of bronze vessels in Luristan. It proved that the samples have been manufactured with a binary copper-tin alloy with a variable tin content that may relates to the application of an uncontrolled procedure to make bronze alloy (e.g. co-smelting or cementation). The presence of elongated copper sulphide inclusions showed probable use of copper sulphide ores for metal production and smelting. Based on metallographic studies, a cycle of cold working and annealing was used to shape the bronze vessels. © 2014 Elsevier Inc. Source

Automation in Construction

Most BIM (Building Information Modelling) systems serve designers well up until now but will have to evolve toward a more user-centered design, focusing on interactive spaces rather than focusing on digital representation. They are lack of information needed in order to create a virtual environment which can interact with users. Such problems will become more prominent in the case of smart spaces where the environment reacts to users' activity. There are no sufficient tools to design and represent real usage of smart space. Achieving this aim, the paper presents Smart-BIM consisting of smart objects which can react to user activities. The created virtual space with Smart-BIM is different from conventional 3D space. Since the resulted space embodies smart objects with the capability of doing certain functions and reacting toward users interaction according to the property sets of objects. A task-based interaction is proposed to apply Smart BIM in a design process. Smart Design systems help end users to experience their daily activity in a virtual environment and understand the space reactions. It can be used as a toolset to improve communications among users and designers in design processes especially in the design of smart environments. Eventually, it is expected that Smart-BIM will lead to match smart technology usability with users' demands. To facilitate further developments of Smart Design systems, a prototyping experiment was done. The prototype application utilizes three typical domestic tasks and several real-time interactions. Scripting the tasks, using smart object managers and using smart home objects make the real-time interactions and system reactions possible. Hence, the prototype gives the opportunity of evaluating users' attitude and expressions toward an interactive and responsive BIM. The results from the first evaluations reveal a positive attitude of users toward the prototype. They also show that when the users can directly execute a task in the virtual model, they can deliver a better comprehension of how smart technologies can be utilized. © 2013 Elsevier B.V. Source

A number of steel plaques in Iran belong to Safavid period (17th century) were examined for their chemical composition and microstructure. The artefacts were analyzed using micro-PIXE, SEM-EDS and reflected light microscopy (OM). According to SEM-EDS and micro-PIXE analyses, it was revealed that the plaques were made of mostly pure iron (approximately 99 wt%). Presence of trace amounts of manganese, sulfur, chromium, silicon, titanium and potassium were identified in the plaques. Metallographic investigation showed that the plaques were made of hypereutectoid steel with a microstructure consisting of spherical particles of carbide in the ferrite and pearlite background. Moreover, the use of ultra-high carbon (UHC) steel with microstructure of pearlite matrix and needle-like Widmanstätten cementite was identified in one plaque. These features showed that Safavid plaques have been made of crucible steel. In addition, it demonstrated that complicated forging/heating cycles have been used for manufacturing of these openwork steel plaques. It was also revealed that in addition to arms and armors, crucible steel has served as an everyday work material in Safavid period in Iran. © 2016 Elsevier Inc. Source

Cyclic voltammetry and differential pulse voltammetry were used to investigate the electrochemical behavior of ascorbic acid (AA) on palladium coated nanoporous gold film (PdNPGF) electrode. The deposition of palladium was done through oxidation of copper UPD layer by palladium ions. This low Pd-loading electrode behaved as the nanostructured Pd for electrocatalytic reaction. The PdNPGF electrode exhibits excellent electrocatalytic behavior by enhancing the AA oxidation peak current due to synergistic influence of the Pd film and NPGF. The kinetic parameters such as electron transfer coefficient, α, was 0.47 and the voltammetric responses of the PdNPGF electrode were linear against concentration of AA in the ranges of 2.50-33.75mM and 0.10-0.50mM with CV and DPV respectively. © 2012 WILEY-VCH Verlag GmbH & Co.

An outstanding style of Persian tilework, which emerged from the north-eastern Iran in the 15th century, was extensively used for decorating architectural facades during the Safavid period (from the 16th through the 18th century). This type of tilework, the so-called haft rang, technically comprises of forming a clay body and firing two glazed layers on top of the body. In the present paper, the first analytical data concerning haft rang tiles is provided. To do so, forty three samples of Safavid haft rang bodies were analysed by wavelength dispersive x-ray fluorescence (WDXRF) and the obtained data were handled by principal component analysis (PCA). The results showed that the 17th century haft rang tiles wherever found are local products; that is, Safavid tile-makers have used local clay sources to make the bodies of haft rang tiles. The analytical data also showed that old tileworks, in general sense, can be simply replaced by newly manufactured tiles or, at least, all tilework revetments in an individual edifice might not have been produced in an identical workshop. Moreover, WDXRF was used as an accurate and precise method to determine the chemical composition and to support compositional classification in provenance studies and can be considered as a reliable alternative for studying the provenance of archaeological ceramics. © 2013 John Wiley & Sons, Ltd.
