In this article optimal design of shear walls is performed under seismic loading. For practical aims, a database of special shear walls is created. Special shear walls are used for seismic design optimization employing the charged system search algorithm as an optimizer. Constraints consist of design and performance limitations. Nonlinear behavior of the shear wall is taken into account and per...

this paper presents some analyses about the robust practical stability of a class of nonlinear affine systems in the presence of non-vanishing perturbations based on the passivity concept. the given analyses confirm the robust passivity property of the perturbed nonlinear systems in a certain region. moreover, robust control laws are designed to guarantee the practical stability of the perturbe...

The overvaluation hypothesis (Miller 1977) predicts that a) stocks are overvalued when there are short selling restrictions and that b) the overvaluation is increasing in the degree of divergence of opinion. We design an experiment that allows us to test these predictions in the laboratory. Our results support the hypothesis that prices are higher in the presence of short selling constraints. T...

In this paper, we investigate the transceiver design under mixed power constraint in which for a given set of antennas, several subsets are constrained by sum power constraints while the other antennas are subject to individual power constraints. This kind of design includes transceiver designs under sum power constraint and per-antenna power constraint as its special cases. In particular, this...

Recognizing the drawbacks of Value-at-Risk (VaR), researchers have advocated the use of Conditional Value-at-Risk (CVaR). However, the current popularity of VaR and Stress Testing (ST) among bank regulators raises the question of whether a risk management system based on both VaR and ST constraints is an effective alternative to a system based on CVaR. We show that when the VaR and ST bounds ar...

In this paper, we have investigated multi-item integrated production-inventory models of supplier and retailer with a constant rate of deterioration under stock dependent demand. Here we have considered supplier’s production cost as nonlinear function depending on production rate, retailers procurement cost exponentially depends on the credit period and suppliers transportation cost as a non-li...
