This paper proposes to extend the band width of narrow band telephone speech signal by employing feed forward back propagation neural network. There are different types of faster training algorithm are available in the literature like Variable Learning Rate, Resilient Back propagation, Polak-Ribiére Conjugate Gradient , Conjugate Gradient with Powell/Beale Restarts , BFGS Quasi-Newton , One-Ste...

The paper of L. Rubinovich and M. Polak [Eur. Phys. J. B 22, 267 (2001)] contains some controversial items. The notation “excess” in connection with various thermodynamic quantities describing solute segregation on the basis of the Langmuir-McLean isotherm is used in a meaning contradictory to general thermodynamics. The approach used to interpret the linear relationship between segregation ent...

The conjugate gradient approach is a powerful tool that used in variety of areas to solve problems involving large-scale reduction. In this paper, we propose new parameter nonlinear algorithms fuzzy equations based on Polak and Ribiere (PRP) method, where prove the descent global convergence properties proposed algorithm. terms numerical results, method has been compared with methods Fletcher (...

Artykuł poświęcony jest czasopismu „Polak w Indiach”, które było organem prasowym Delegatury Ministerstwa Pracy i Opieki Społecznej. Periodyk ukazywał się Indiach latach 1943–1948. Był to dwutygodnik, początkowo integrujący Polaków okresie II wojny światowej, a potem zaspokajający głód wiedzy o sytuacji na ziemiach polskich, tak bardzo od Indii odległych. Gazeta stanowiła również kronikę poloni...

uring the reign of the fourth Qajar king, Naser-ad-Din Shah (who reigned from 1848–1896), the Chief Minister, Amir Kabir, was involved in modernization of Iran. He founded the first modern higher educational institute in Iran the so called “Dar al-Fonun” (House of Techniques) in 1851. One of the subjects taught there was medicine; now, it is considered a major step in promulgation of modern med...
