The BFGS methods is a method to solve an unconstrained optimization. Many modification have been done for solving this problems. In this paper, we present a new scaled hybrid modified BFGS. The new scaled hybrid modified BFGS algorithms are proposed and analyzed. The scaled hybrid modified BFGS can improve the number of iterations. Results obtained by the hybrid modified BFGS algorithms are com...

water deficit is one of the most common constraints to crop productivity in the world and iran. in order to study effect of drought stress on morphologic traits, yield and yield components of 34 hybrids of corn, an experiment was carried out based of complete randomized block design with three replication under f.c. irrigation and drought stress in khorasan razavi agricultural research and natu...

The paper addresses a new QRS complex geometrical feature extraction technique as well as its application for electrocardiogram (ECG) supervised hybrid (fusion) beat-type classification. To this end, after detection and delineation of the major events of ECG signal via a robust algorithm, each QRS region and also its corresponding discrete wavelet transform (DWT) are supposed as virtual images ...

Annually, many people are irradiated for diagnostic and therapeutic purposes. Assessment of radiation dose and its related risks to patients are important issues in radiation protection dosimetry. The complex mathematical calculations of the absorbed and effective doses are now done with computers. The calculations are performed with the help of anthropomorphic computational models of human bod...

The U.S. has decreased in prominence in the global marketplace in recent years because competing countries have learned to excel in cooperation . We are investigating and developing a system that will provide: 1. computer-assisted cooperation among human designers and manufacturing engineers by promoting parallel design and manufacturing analyses and limiting the over-constraining which occurs ...

With the advancement in Networking and Telecommunication technologies and the increase in mobility necessities, Wireless Networks and its related technologies are becoming more popular nowadays. Since, Wireless and Mobile Networks are still evolving, the technology requires much more optimizations. The traditional Base Station (BS) based Wireless networks and Ad-hoc Wireless networks, apart fro...
