In recent years, soft computing methods have generated a large research interest. The synthesis of the fuzzy logic and the evolutionary algorithms is one of these methods. A particular evolutionary algorithm (EA) is differential evolution (DE). As for any EA, DE algorithm also requires parameters tuning to achieve desirable performance. In this paper tuning the perturbation factor vector of DE ...

bivariate features, obtained from multichannel electroencephalogram (eeg) recordings, quantify the relation between different brain regions. studies based on bivariate features have shown optimistic results for tackling epileptic seizure prediction problem in patients suffering from refractory epilepsy. a new bivariate approach using univariate features is proposed here. differences and ratios ...

Global Positioning System (GPS) is proven to be an accurate positioning sensor. However, there are several sources of errors such as ionosphere and troposphere effects, satellite time errors, errors of orbit data, receivers errors, and errors resulting from multi-path effect which reduce the accuracy of low-cost GPS receivers. These sources of errors also limit the use of single-frequency GPS r...

Purpose The authors measure the cost of equity to earnings yield differential for a sample 2,035 non-financial firms. In series Logit and Tobit regressions, examine if is related dividend policy in manner predicted by agency theory. Design/methodology/approach Agency theory says firm's optimal partially determined relationship between capital. When higher (lower) than yield, firms are motivated...

An increasing amount of users' sensitive information is now being collected for analytics purposes. Differential privacy has been widely studied in the literature to protect information. The parameter bounds about data set leaked by noisy output. Oftentimes, a needs be used answering multiple queries, so level protection may degrade as more queries are answered. Thus, it crucial keep track budg...

Discrimination in the workplace can be a source of opportunity costs for firms that desire to enter new market. In this article, we model how an exogenous technological change introduces both potential workers labor market and, as economy grows, set consumers conquer. We then use differential show payoff firm discriminates loses from same demographic. Our results imply anti-discriminatory polic...
