This paper explores the understanding of architectural spaces driven by knowledge that animals communicate modifying environment, in which they live. The way environment forms an interaction, is referred to as stigmergy, a mediated form animal interaction. elaborates on process colonies with their living and leave different kinds spatial traces. argues stigmergy can be potentially used basis pr...

While the SoftAssign algorithm imposes a two-way constraint embedded into the deterministic annealing scheme and the EMICP algorithm imposes a one-way constraint, they represent the state of the art technique for the automatic registration of overlapping free form shapes. They both have a time complexity of O(n). While the former has a space complexity also of O(n), the latter has a space compl...

We present and study a family of metrics on the space of compact subsets of Ê N (that we call " shapes "). These metrics are " geometric " , that is, they are independent of rotation and translation; and these metrics enjoy many interesting properties, as, for example, the existence of minimal geodesics. We view our space of shapes as a subset of Banach (or Hilbert) manifolds: so we can define ...

Abstract. We propose a new method to recognize 3D objects using segmentbased stereo vision. Predefined object models are compared with 3D boundaries which are extracted by the stereo vision. Boundaries may be straight lines, circular arcs and free-form curves. The models consist of the local shapes and the whole shapes of the boundaries. The models are constructed from samples of real objects o...

let $(m^{2n},g)$ be a real hypersurface with recurrent shapeoperator and tangent to the structure vector field $xi$ of the sasakian space form$widetilde{m}(c)$. we show that if the shape operator $a$ of $m$ isrecurrent then it is parallel. moreover, we show that $m$is locally a product of two constant $phi-$sectional curvaturespaces.

Involving the Ricci curvature and the squared mean curvature, we obtain basic inequalities for different kind of submaniforlds of a Sasakian space form tangent to the structure vector field of the ambient manifold. Contrary to already known results, we find a different necessary and sufficient condition for the equality for Ricci curvature of C-totally real submanifolds of a Sasakian space form...

In study of sema and its related architectural spaces in chalabioghlu khanghah, the main goal is to understand the most important principles of spaces formation in the complex. To achieve this goal, at the very first place it’s necessary to study Sema tradition itself in the second step, architecture of the complex should be taken to consideration, both as a whole and in details. Acquiring all ...

This study is concentrated on the natural frequencies and mode shapes of a simple three-member space frame coupled with a dynamic vibration absorber. The dynamic vibration absorber is modeled as a six-degree-of-freedom mass-spring system. For the first time, the free vibration of an elastic structure with a six-degree-of-freedom mass-spring system is found. Each member of the space frame has un...
