Bankruptcy prediction is a major issue in classification of companies. Since bankruptcy is extremely costly, investors, owners, managers, creditors, and government agencies are interested in evaluating the financial status of companies. This study tried to predict bankruptcy among companies registered in Tehran Stock Exchange (Iran) by designing imperialist competitive algorithm and genetic alg...

BACKGROUND Bowlby and Ainsworth hypothesized that maternal responsiveness is displayed in the context of infant distress. Depressed mothers are less responsive to infant distress vocalizations (cry) than non-depressed mothers. The present study focuses on acoustical components of infant cry that give rise to responsive caregiving in clinically depressed (n = 30) compared with non-depressed moth...

We derive a class of extended one-step methods of order m for solving delay-differential equations. This class includes methods of fourth and fifth order of accuracy. Also, the class of these methods depends on two free parameters. A convergence theorem and convergence factor of these methods are given. In addition, we investigate the stability properties of these methods. The results of the ar...

background: sound is one of the most important factors threatening workers’ health. the most efficient and practical method for controlling noise pollution is the use of sound-absorbing materials. impedance tube with two microphones is used to determine the sound absorption coefficients and should be tested periodically for accuracy and efficiency. the purpose of present study was assessing the...

OMR (Optical Music Recognition) programs have been available for years, but they still leave much to be desired in terms of accuracy. We studied the feasibility of achieving substantially better accuracy by using the output of several programs to “triangulate” and get better results than any of the individual programs; this multiplerecognizer approach has had some success with other media but, ...

The Department of Defense and Department of Homeland Security use many threat detection systems, such as air cargo screeners and counter-improvised-explosive-device systems. Threat detection systems that perform well during testing are not always well received by the system operators, however. Some systems may frequently “cry wolf,” generating false alarms when true threats are not present. As ...

This paper is concerned with reconstruction theories of which-questions, and shows that one major limitation of these approaches lies in the way these theories derive de dicto readings of sentences such as Mary knows which children cried. Specifically, we show that when a wide range of de dicto facts is considered, an analysis where wh-phrases never reconstruct must be preferred over the recons...
