Nowadays, in order to increase construction of tall structures, the importance choosing optimum systems, with a huge energy absorption capacity against wind and earthquake loads, has been widely considered. Since four decades ago, steel shear walls had used as stiff high performance lateral system. This study is about effect concrete filled tubes (CFT) columns vertical boundary elements wall on...

In this paper, we make a modification to the LS conjugate gradient method and propose a descent LS method. The method can generates sufficient descent direction for the objective function. We prove that the method is globally convergent with an Armijo-type line search. Moreover, under mild conditions, we show that the method is globally convergent if the Armijo line search or the Wolfe line sea...

The paper presents a study of a pilot plant treating light greywater for seven flats. The pilot plant combines biological treatment (RBC) with physicochemical treatment (sand filtration and disinfection). The pilot plant produced effluent of excellent quality, meeting the urban reuse quality regulations, and was very efficient in TSS turbidity and BOD removal: 82%, 98% and 96%, respectively. CO...

the concept of fuzzy soft γ-ring is introduced; and some properties of fuzzy soft γ-rings are given. then the definitions of fuzzy soft γ-ideals are proposed and some of their theories are considered.

Maneuvers of a nonholonomic vehicle in a structured dynamic environment are considered. The paper focuses on motion generation and control methods to autonomously perform lane following/changing and parallel parking maneuvers. Lane following/changing involves the tracking of a nominal trajectory in the traac lane, and the generation and tracking of local lane-changing trajectories, for instance...

Availability of parking within a short period of time is a critical problem. Drivers are wasting a lot of time circling around on campus multiple times to try to find a vacant spot to park especially during the peak hours. In turn, this problem is causing another one – that of wasting a lot of fuel and thus polluting the surroundings. A literature review that investigates thoroughly existing pa...

We present the language S Graph n the core of a multi level metaprogramming environment for exploring foundational issues of self applicable online program specialization We illustrate how special purpose S Graph n primitives can be used to obtain an e cient and conceptually simple encoding of programs as data objects The key feature of the encoding scheme is the use of nu merical indices which...

This paper is an experimental study on the behavior of vertical shear link in the single and double configurations. There have been three specimens selected for examining the effects of different details .The first specimen was an I section with no stiffener, while the second specimen composed of I section with stiffeners designed according to AISC 2005. Third specimens were composed of two I s...
