in this paper a discrete big bang-big crunch algorithm is applied to optimal design of reinforced concrete planar frames under the gravity and lateral loads. optimization is based on aci 318-08 code. columns are assumed to resist axial loads and bending moments, while beams resist only bending moments. second-order effects are also considered for the compression members, and columns are checked...

The big bang-big crunch (BB-BC) algorithm is a popular metaheuristic optimization technique proposed based on one of the theories for the evolution of the universe. The algorithm utilizes a two-phase search mechanism: big-bang phase and big-crunch phase. In the big-bang phase the concept of energy dissipation is considered to produce disorder and randomness in the candidate population while in ...

this article presents the application of two algorithms: heuristic big bang-big crunch (hbb-bc) and a heuristic particle swarm ant colony optimization (hpsaco) to discrete optimization of reinforced concrete planar frames subject to combinations of gravity and lateral loads based on aci 318-08 code. the objective function is the total cost of the frame which includes the cost of concrete, formw...

Two new species of the genus Omyomymar Schauff (Hymenoptera: Mymaridae), sudhiri sp. nov. Anwar & Zeya and supremus are described from Indian Himalayan regions. An identification key to is provided. All previously recorded analyzed discussed.

This paper proposes a novel time-concatenated turbo equalization technique, chained turbo equalization (CHATUE), that allows block transmission systems to eliminate the guard interval (GI), while achieving excellent performance. The proposed CHATUE algorithm connects turbo equalizers neighboring in time, so that they exchange information about their inter-block-interference components in the fo...

In a large part of his literary production, the Egyptian novelist Jamāl al-Ghīṭānī (1945-2015) aimed at rewriting Arabic heritage in order to contest Western novel hegemony and criticising Gamal Abdel Nasser (Jamāl ʿAbd al-Nāṣir) Anwar Sadat’s (Anwar al-Sādāt) authoritarianism. this study we will analyse Khiṭaṭ (1981), which author narrates police state free market economy applying spatial orga...
