A sensitive and rapid ELISA for quantitation of seed globulins is described. This method employs conjugation of pigeon pea (Cajanus cajan) globulin antibodies and the enzyme peroxidase together with dextran. Using this conjugate, proteins as low as 0.1 ng were detected. Dextran conjugate has a ten-fold greater efficiency of quantitating pigeon pea globulins than the commercial goat anti-rabbit ...

Ground-conjugate wide eld AO is presented and preliminary performance results are given, which show that signi cant seeing improvement can be achieved over 10-20 arcmin eld of view. A proposal for an ELT AO system is sketched.

We discuss the construction of algebraic multilevel preconditioners for the conjugate gradient method and derive explicit and sharp bounds for the convergence rates. We present several numerical examples that demonstrate the efficiency of the preconditioner. sparse approximate inverse, sparse matrix, algebraic multilevel method, preconditioning, conjugate gradient method, Krylov subspace method...

Conjugate gradient methods are widely used for unconstrained optimization, especially large scale problems. Most of conjugate gradient methods don’t always generate a descent search direction, so the descent condition is usually assumed in the analyses and implementations. Dai and Yuan (1999) proposed the conjugate gradient method which generates a descent direction at every iteration. Yabe and...

In this paper, by using the smoothing Fischer-Burmeister function, we present a new smoothing conjugate gradient method for solving the nonlinear nonsmooth complementarity problems. The line search which we used guarantees the descent of the method. Under suitable conditions, the new smoothing conjugate gradient method is proved globally convergent. Finally, preliminary numerical experiments sh...

A nonlinear conjugate gradient algorithm which is a modification of the Dai and Yuan [Y.H. Dai and Y, Yuan, A nonlinear conjugate gradient method with a strong global convergence property, SIAM J. Optim., 10 (1999), pp.177-182.] conjugate gradient algorithm satisfying a parametrized sufficient descent condition with a parameter k δ is proposed. The parameter k δ is computed by means of the conj...
