The aim of the present paper is to find efficient method computation wave-making resistance a ship using mitchell’s integral. computational schemes described in publications suggest use simple quadratures (trapezoidal and Simpson’s rule) with fixed number integration’s intervals. This approach assumes manual setup algorithm for calculating each new makes it difficult estimate error obtained res...

The collocation method based on cubic B-spline, is developed to approximate the solution of second kind nonlinear Fredholm integral equations. First of all, we collocate the solution by B-spline collocation method then the Newton-Cotes formula use to approximate the integrand. Convergence analysis has been investigated and proved that the quadrature rule is third order convergent. The presented...

L'expedition scientifique francaise, sous le commandement du capitaine Baudin, visita l'Australie entre 1801 et 1803. Parmi les savants, il y avait Louis Depuch (1774-1803) Charles Bailly (1777-1844), premiers geologues a etudier l geologie long des cotes de ce continent. Leurs travaux en Australie furent fortement influences par idees celebres Dolomieu (1750-1801)et Horace-Benedict Saussure (1...

The paper builds a Variance-Gamma (VG) model with five parameters: location (?), symmetry (?), volatility (?), shape (?), and scale (?); studies its application to the pricing of European options. results our analysis show that five-parameter VG is stochastic ?(?,?) Ornstein–Uhlenbeck type process; associated Lévy density KoBoL family order ?=0, intensity ?, steepness parameters ??2??2?4+2??2 ?...
