In this paper, by using the sequence of adjointable operators from pro-C*-algebra $ mathcal{A} $ into a Hilbert $ mathcal{A} $-module $ E $. We introduce frames with bounds in pro-C*-algebra $ mathcal{A} $. New frames in Hilbert modules over pro-C*-algebras are called standard $ ast $-frames of multipliers. Meanwhile, we study several useful properties of standard $ ast $-frames in Hilbert modu...

the art of qajar period includes many unique features and themes. one of the most exceptional features of qajar artworks (painting on tiles) is women motifs depicted at semiprivate and private spaces, at houses of nobilities, and palaces. qajar women in these paintings interact with foreign women’s identity and they have shown a new face of iranian women. the archi-myth of qajar period is inclu...

optimization of structures for minimum weight has become important in the recent designs. in this study, a genetic optimization algorithm for weight minimization of steel frames has been used. the genetic algorithm is an optimization and search technique based on the principles of genetics and natural selection. constraints regarding material strength and serviceability are taken from “aisc cod...

In the present study, ten steel-moment resisting frames (SMRFs) having different numbers of stories ranging from 3 to 20 stories and fundamental periods of vibration ranging from 0.3 to 3.0 second were optimized subjected to a set of earthquake ground motions using the concept of uniform damage distribution along the height of the structures. Based on the step-by-step optimization algorithm dev...

Direct Displacement-Based Design (DDBD) is a performence-based seismic design method that has been proposed and well developed over the past two decades to design RC frame structures, shear walls and bridges. In this method, the behavior of a multi-degree-of-freedom (MDOF) sysytem is approximaeted by an equivalent single-degree-of-freedom (SDOF) substitute structure. Although this method has be...

In this study, we examine some properties of Salkowski curves in $\mathbb{E}^{3}$. We then make sense the angle $(nt)$ parametric equation curves. provide relationship between and binormal vector Darboux Through angle, obtain unit direction curve. Finally, calculate modified orthogonal frames with both curvature torsion give relationships Frenet frame
