theory is a base for all scientific disciplines. theorizing is an important branch in architecture too. there are a little reference that tries to define theory and show the differences between theory in architecture and theory in other disciplines. this article aimed to show the characteristics of architectural theory. at first we try to review different books and articles which are written on...

the main aim of this paper is to extend the recently developed methods for calculating the buckling loads of planar symmetric frames to include the effect of semi-rigidity of the joints. this is achieved by decomposing a symmetric model into two submodels and then healing them in such a manner that the ::::union:::: of the eigenvalues of the healed submodels result in the eigenvalues of the ent...

the wisdom of crowds, an innovative theory described in social science, claims that the aggregate decisions made by a group will often be better than those of its individual members if the four fundamental criteria of this theory are satisfied. this theory used for in clustering problems. previous researches showed that this theory can significantly increase the stability and performance of lea...

In this seminar, we shall introduce semi-infinite manifolds and show how one may define cohomology theories dependent on this semiinfinite structure. In particular, we shall define a de Rham theory. With certain alterations, this is calculable for Wiener manifolds. The goal, however, is to calculate the theory for loop spaces and this is, as yet, an unsolved problem. 1 Semi-Infinite Theory The ...

the hydrogen abstraction reaction of oh radical with ch3ch2ocf2chf2 (hfe-374pc2) is investigated theoretically by semi-classical transition state theory. the stationary points on the potential energy surface of the reaction are located by using kmlyp density functional method along with 6-311++g(d,p) basis set. vibrational anharmonicity coefficients, xij, required for semi-classical transition ...
