Amir Z. Averbuch,Pekka Neittaanmäki,Valery A. Zheludevve a linear integral equation, which is then solved by the Tikhonov method with the identity as the regularization operator. We prove in this paper that the resulting equation is well-condition and has clustered spectrum. Hence if the conjugate gradient method is used to solve the equation, we expec

Amir Z. Averbuch,Pekka Neittaanmäki,Valery A. Zheludevtechnique was proposed by Gilbert and Schreiber in 1980 but never implemented and tested. Like other techniques for ordering sparse matrices for LU with partial pivoting, our new method preorders the columns of the matrix (the row permutation is chosen by the pivoting sequence during the numerical f

Amir Z. Averbuch,Pekka Neittaanmäki,Valery A. Zheludevof the inelastic mean free paths. This effect arises when a monoenergetic electron beam bombards a solid target and some of the electrons are scattered without energy loss.The description of the flow can be written as an integral equation and may be solved by Monte Carlo methods..In this paper we in

Composite multilayered pressure vessels are capable of yielding high pressures with very light weight, where they can provide
