Aims Building information modeling (BIM) is a process based on three-dimensional model that has provided tools to change the educational and professional approach. The purpose of this study is to test an active and constructive educational structure with a focus on the BIM approach and the application of this method in promoting the performance and creativity of architecture students in building technology courses.
Methods The research test was performed by quasi-experimental method with experimental and control groups using pretest and posttest. Pre-test was performed by Torrance creativity test and two design tasks and Mann-Whitney U test was used for post-test.
Findings The findings of the analysis of pre-test results did not show a significant difference between the two groups. But by conducting a post-test, the experimental group in the indicators of concept technicality, coordination of executive issues, site technical plan, quantity and quality of phase two plans, executive details, presentation of design and overall score had a significant advantage over the control group.
Conclusion The results show that the use of the proposed educational method was effective in improving the overall performance of students in the experimental group and had a significant advantage over the performance of the control group. Regarding the promotion of studentschr('39') creativity, no significant difference and superiority was observed between the two groups, but the average ranks of students in the experimental group were significantly better than the control group. Therefore, the research results confirm the increase in studentschr('39') learning using this educational approach.

The present Research has surveyed the foreign policy of the Islamic Republic of Iran vis-à-vis the Republic of Azerbaijan. Based on some of the most important geographical and geopolitical realities that exist between the two states, by presenting one main question and two hypotheses, used as guide into a thorough geopolitical assessment of the issue. Based on the findings, we come to this conclusion that the none-cordial disposition of the Republic of Azerbaijan towards Iran, and some of the uncharted pasturings and unspecified strategies by the Islamic Republic of Iran render ineffective so many positively positoned areas of common geographical and/or geopolitical interests such as territorial contiguity, common religious tendency (both Shiite), common ethnicity, common economic interests (agricultural and irrigation possibilities), common cultural and historical backgrounds. Unfortunately, the continued policies between the two states have further made all these possibilities to render ineffective. The main outcome of the research shows that some of the issue are resultant from a suspected nationalistic disposition on the part of the Iranians; and similarly, a persistent attitude of none cordiality from the Azeris. Moreover, the Republic of Azerbaijan has yet to present a logical and pragmatic reason to explain its negative diplomatic strategy against the Islamic Republic of Iran That could justify its distrustful policy towards iran. The research consequently has proposed the following general aims and strategies to be implemented in Iran’s faring policy towards the Republic of Azerbaijan: General aim: the faring policy of the Islamic Republic of Iran in relation to the Republic of Azerbaijan is determined by geographical and geopolitical realities that exist between the two states. Strategy: to develop mutual relations based on the need for neighborly dispositions, to understand the geopolitical dictates of time and space, common national interests and aims,economic cooperation,and to explore other avenues that would develop mutual trust in order to broaden cooperation between the two states.

In this paper, squeeze film damping in a micro-beam resonator based on micro-polar fluid theory has been investigated. The proposed model for this study consists of a clamped-clamped micro-beam suspended between two fixed stratums. The gap between the micro-beam and stratums is filled with air. Equation of motion governing the transverse deflection of the micro-beam based on strain gradient theory and also non-linear Reynolds equation of the fluid field based on micro-polar theory have been non-dimensionalized, linearized and solved simultaneously to calculate the quality factor of the squeeze film damping. The effect of non-dimensional length scale parameter of the air and micro-beam for different values of micro-polar coupling parameter has been investigated. It has been shown that applying micro-polar theory underestimates and also applying strain gradient theory overestimates the values of quality factor that are obtained in the case of classic theory. The quality factor of the squeeze film damping for different values of non-dimensional length of the beam, squeeze number and non-dimensional pressure have been calculated and compared to the obtained values of quality factor based on classic theory.

In this paper, natural convection of Cu-Water nanofluid inside an enclosure which is partially filled with porous media, with internal heat generation has been studied numerically. Cu-water nanofluid was used where Maxwell and Brinkmen models determine its properties. Due to the low velocity of nanofluid, Darcy-Brinkman equation used for the modeling of porous media. In order to gain the maximum energy from the temperature dependent heat source, different parameters such as Rayleigh number, volume fraction of nanoparticles, porosity of porous matrix and heat conduction ratio has been investigated. The results show that increasing the volume fraction of nanofluid increases Nusselt number at all porosities and Nusselt will further increases at lower porosities. Changes of thermal conductivity ratio were effective only at low porosities and causes to fast conduction of generated heat and two-fold increase in Nusselt number. Moreover the porosity changes at different thermal conductivity ratio Cause to minimum Nusselt at the porosity of 0.4 to 0.6. Increasing Rayleigh number will lead to nanofluid penetration increase into the porous matrix and with further matrix cooling more increase in Nusselt number in all porosity ranges will be achieved.
