The Islamic Azad University of Shiraz is a private university located in Shiraz, Iran. It is a part of private chain of universities in Iran called the Islamic Azad Universities.The Islamic Azad University of Shiraz with over 290 faculty and academic staff, 82,000 square meters of educational space, 7,500 square meters of administration space, 15,200 square meters of sporting space, is the biggest private university in the southern region of Iran.The headquarters of the Islamic Azad University is in Tehran, Iran. The Islamic Azad University was founded in 1982 and currently has an enrollment of 1.7 million students, 30,000 Alumni and 35,000 Administrators making it the world's third largest. Over 3.5 million students have graduated from the Islamic Azad University since its establishment. Islamic Azad University has a total area of 16 million square meters and over 440 branches across Iran and also in other countries around the world. It has also international branches and universities in the U.A.E, United Kingdom, Tanzania, Lebanon, Afghanistan and Armenia and has plans to establish more branch campuses in Malaysia, Canada, and Tajikistan in the near future.Over the years, the university has accumulated assets estimated to be worth between $20 and $25 billion. The total Area of the University is said to be 20 million square meters.Some 4 million students have graduated from this university to this date, which has made it possible for a lot of people to get access to higher educations and better employment prospects. In the recent years a lot of effort has been made to expand the graduate studies at the Islamic Azad University. The Islamic Azad University has about 200,000 Master's Degree students and about 20,000 PhD level students.The university system also operates a news agency similar to ANA, named "Azad News Agency".Islamic Azad University's activities quickly expanded throughout the country, so that today thousands of students are enrolling every year. Not relying on government funding, it receives charitable donations and charges tuition fees.The Islamic Azad University also operates some 617 schools throughout the country, these schools are known as SAMA .The degrees and certificates issued by this university are recognized by the Ministry of Science and Higher Education. Post-graduate degrees have been offered in many different branches of Islamic Azad University. Wikipedia.

The three-dimensional (3D) free vibration of laminated cylindrical panels with finite length and functionally graded (FG) layers is presented. The cylindrical panels with two opposite axial edges simply supported and arbitrary boundary conditions at the curved edges can be analyzed via the present approach. The material properties vary continuously through the layers thickness. In order to accurately model the variation of the displacement components through the panel thickness, a layerwise-differential quadrature method (LW-DQM) is employed in this direction. Also, the in-plane variations of the displacement components are approximated using the trigonometric series in the circumferential direction and the DQM in the axial direction. The fast rate of convergence and accuracy of the method are demonstrated through different examples. As applications of the present approach, the free vibration of two common types of sandwich cylindrical panels, i.e. sandwich panels with FG face sheets and ceramic core and sandwich panels with FG core and ceramic/metal face sheets, and also bi-layered FG cylindrical panels are studied. The effects of geometrical and material parameters together with the boundary conditions on the frequency parameters of these types of panels are investigated. © 2013 Elsevier Ltd. Source

In the present study, some modifications on the firefly algorithm are presented to improve its performance. The firefly algorithm is a recently developed robust metaheuristic optimization technique which mimics the social behavior of fireflies based on their flashing characteristics. To improve its performance three basic modifications are proposed in the present work. These modifications consist of adding memory, adding newborn fireflies and proposing a new updating formula. To evaluate the applicability of the proposed method, three classical engineering design optimization problems and three sizing optimization of truss structures are solved and results are compared with those available in the literature. It is observed that the proposed method can effectively be used in solution of engineering design optimization problems. Source

Solvent effects on the complex formation of osmium tetroxide (which is the most reliable reagent available for the cis-hydroxylation of alkenes) and pyridine were investigated using spectrophotometric techniques in different solvents (benzene, chloroform, acetone, acetonitrile, anisole, tetrahydrofuran, nitrobenzene and nitromethane). The enthalpy and entropy exhibit opposing effects on stability constant with the change in solvent. In these solvents, the entropy and enthalpy of the reaction are found to be mainly influenced by the donor number (DN) of the solvents. © 2009 Elsevier Ltd. All rights reserved. Source

In this paper we study modified Chaplygin gas which has viscosity for the case of arbitrary α instead of α=0.5. We obtain behavior of the energy density of modified Chaplygin gas with respect to the constant and time-dependent bulk viscosity. We find also, numerically, effect of α on the energy density. © 2013 Springer Science+Business Media New York. Source

Fostering demand response (DR) through incentive-based and priced-based programs has always great impact on improvement of efficiency and reliability of the power systems. The use of DR lowers undesirable effects of failures that usually impose financial costs and inconveniences to the customers. Hence, quantifying the impact of demand response programs (DRPs) on reliability improvement of the restructured power systems is an important challenge for the independent system operators and the regional transmission organizations. In this paper, the DR model which treats consistently the main characteristics of the demand curve is developed for modeling. In proposed model, some penalties for customers in case of no responding to load reduction and incentives for customers who respond to reducing their loads are considered. In order to make analytical evaluation of the reliability, a mixed integer DC optimal power flow is proposed by which load curtailments and generation re-dispatches for each contingency state are determined. Both transmission and generation failures are considered in contingency enumeration. The proposed technique is modeled in the GAMS software and solved using CPLEX as a powerful mixed integer linear programming (MILP) solver. Both supply-side reliability for generation companies and demand-side reliability for customers are calculated using this technique. In order to simulate customers' behavior to different DRPs in a real power network, the proposed DR model is used and evaluated over Iranian power network. In order to investigate the reliability effects of DRPs based on proposed reliability method, DRPs based on the DR model are implemented over the IEEE RTS 24-bus test system, and reliability indices for generation companies, transmission network and customers are calculated. Using proposed performance index, the priority of the DRPs are determined from view point of customers, generation companies, transmission network and the whole system in IEEE RTS. © 2013 Elsevier Inc.
