PNEUllOTHORAX DE L'ENFANT  Presentation de 17 cas. Revue de la litterature Par: Marandian M.H., Momenzadhe A., Wali­zade G., Kabiri M., A'skari H. et Movasat M.  Durant deux ans et demi, 17 cas de pneumo­thorax ont ete observes dans le service de Pedia­trie de !'Hospital Pahlavi de l'Univm-site de Teheran:  1)9 de ces malades etaient ages de moins d'un an. Le malade le plus age atteint de pn...

this paper presents a proof of stirling's formula using haar wavelets and some properties of hilbert space, such as parseval's identity. the present paper shows a connection between haar wavelets and certain sequences.

 This paper deals with a short term forecasting non-stationary time series using wavelets and splines. Wavelets can decompose the series as the sum of two low and high frequency components. Aminghafari and Poggi (2007) proposed to predict high frequency component by wavelets and extrapolate low frequency component by local polynomial fitting. We propose to forecast non-stationary process u...

Background: Carotid artery stenting (CAS) has recently been recommended as an alternative to carotid endarterectomy (CEA) by some clinicians. Objective: This study was designed to evaluate the success rate and in-hospital and 30-day adverse events in our first experiences in Iran for CAS with protection devices, to document our results and guide further use of CAS. Methods: From December 2...

in this paper, we develop an efficient legendre wavelets collocation method for well known time-fractional heat equation. inthe proposed method, we apply operational matrix of fractionalintegration to obtain numerical solution of the inhomogeneoustime-fractional heat equation with lateral heat loss and dirichletboundary conditions. the power of this manageable method isconfirmed. moreover, the ...

In this article, we present a constructive technic of biorthogonal nonstationary wavelets (Bior-NSW) family which are proposed by [12], and perform comparative study between the classical Daubechies constructed wavelets, prooved dominance in approximation different kinds signals.

In this paper, we develop a framework to obtain approximate numerical solutions to ordi‌nary differential equations (ODEs) involving fractional order derivatives using Legendre wavelets approximations. The continues Legendre wavelets constructed on [0, 1] are uti‌lized as a basis in collocation method. Illustrative examples are included to demonstrate the validity and applicability of the techn...
