Nowadays, given the rapid growth of socioeconomic issues, more emphasis is being placed upon providing the consumers with higher quality services. Consequently, many modern societies are seeking to use new energy management systems to reduce the environmental pollutions and operational costs resulting from electrical energy generation systems. So, benefiting from various renewable energy resour...

This paper presents an efficient optimization procedure to find the optimal shapes of double curvature  arch  dams  considering  fluid–structure  interaction  subject  to  earthquake  loading. The optimization is carried out using a combination of the magnetic charged system search, big bang-big crunch algorithm and artificial neural network methods. Performing the finite element  analysis  dur...

In this study, topology optimization is applied to concentrically braced frames in order to find economical solutions for conventional structural steel frames. Differential Evolution Algorithm and Dolphin Echolocation Optimization are applied for structural optimization. Numerical examples are studied and results of comparison with other meta-heuristic algorithms, including Genetic Algorithm, A...

This paper presents a Big Bang Big Crunch concept based search algorithm for automatic generation of structural software tests. Test cases are symbolically generated by measuring fitness of individuals with the help of branch distance based objective function. Evaluation of the test generator was performed using ten real world programs. Some of these programs had large ranges for input variable...

For a long time, there were two main theories related to how our universe would end. These were the Big Freeze and the Big Crunch. In short, the Big Crunch claimed that the universe would eventually stop expanding and collapse in on itself. This collapse would result in...well...a big crunch (for lack of a better term). Think “the Big Bang”, except just the opposite. That’s essentially what the...

Among the different lateral force resisting systems, shear walls are of appropriate stiffness and hence are extensively employed in the design of high-rise structures. The architectural concerns regarding the safety of these structures have further widened the application of coupled shear walls. The present study investigated the optimal dimensional design of coupled shear walls based on the im...
