In this article, we tried to emphasis in how the range of torsionally stiff and flexible single story buildings works. The designed base was according to provisions of the Canadian standard, 2005 NBCC. The behavior of nonlinear dynamic time history of eight building models subjected to seven horizontal bi-directional ground motions compatible with design spectra are investigated. These models c...

In this study, the effective parameters on the inelastic response of asymmetric buildings is evaluated for an ensemble of real Iranian earthquake records by considering soil-structure interaction. Then, the design eccentricity obtained from the inelastic dynamic soil-structure analysis is compared with the design eccentricity of seisimic codes of Iran, ATC-3, New Zeland, Canada, Mexico, Austral...

an algebraic construction for constant dimension subspace codes is called orbit code. it arises as the orbits under the action of a subgroup of the general linear group on subspaces in an ambient space. in particular orbit codes of a singer subgroup of the general linear group has investigated recently. in this paper, we consider the normalizer of a singer subgroup of the general linear group a...

In Europe, Eurocodes are the set of standards for structural design, integrating all specific National experiences and research outputs. However, about ten years have elapsed since the official issue of these codes. Within this last decade, European codes for structural design have been extensively used by designers and practitioners, thus showing the lacks and fallacies in the application of s...

In this paper, we study the linear codes over the commutative ring R = Z4 + vZ4, where v2 = v. We define the Gray weight of the elements of R and give a Gray map from Rn to Z2n 4 , which lead to the MacWillams identity of the linear code over R. Some useful results on self-dual code over R are given. Furthermore, the relationship between some complex unimodular lattices and Hermitian self-dual ...

This paper describes the coupling of FEFLO, a general purpose compressible and incompressible flow solver based on adaptive unstructured grids, with SIMPACT, a general purpose, large deformation, explicit structural dynamics code developed at the Center for Numerical Methods in Engineering (CIMNE). Details on the codes as well as the coupling strategy employed are given. An example illustrates ...

We propose that an essential factor on the origin of genetic codes is a balanced accomplishment of robustness and changeability, two antithetical, but fundamental, properties for the survival and evolution of organisms. These measures are defined as the intrinsic properties of genetic codes. An evaluation of these properties explains the structural regularity of genetic codes, estimates the ord...

| An e cient recursive Log-MAP algorithm for binary linear block codes is proposed. This algorithm is devised based on the structural properties of the minimal trellis diagram. Simulation results show that for some well known codes, the proposed algorithm reduces decoding complexity signi cantly compared to the conventional Log-MAP algorithm.
