In this paper‎, ‎two extended three-term conjugate gradient methods based on the Liu-Storey ({tt LS})‎ ‎conjugate gradient method are presented to solve unconstrained optimization problems‎. ‎A remarkable property of the proposed methods is that the search direction always satisfies‎ ‎the sufficient descent condition independent of line search method‎, ‎based on eigenvalue analysis‎. ‎The globa...

Context. Pulmonary hypertension is a common clinical problem encountered in day-to-day practice. Drug therapy forms the backbone of management and appropriate drug selection is based upon the underlying causes. The options available are widening with availability of newer therapeutic agents and thus it becomes necessary to be updated with the recent developments. Objective. To review the existi...

This paper introduces a varianceand angle-normalized version of the least-squares order-recursive lattice (LSORL) smoother, say the normalized LSORL smoother, via a geometric approach. The normalized LSORL smoother has excellent round-o. noise properties and inherits all the other advantages of the normalized LSORL as well. Simulation results show that the normalized LSORL smoother outperforms ...

A method for enhancing the reliability of N-version software is proposed. A pilot study presents experimental results on data diversity, in which retry with a mutation-directed variation in input is attempted after system failure. These results suggest that mutation analysis could be valuable in the design of fault-tolerant software systems.

in this work, harmony search meta-heuristic optimization algorithm has been developed for aerodynamic shape optimization problem for the first time. the aerodynamic shape, which has been investigated, is an airfoil with parces method for its shape parameterization. the problem was minimization of aerodynamic objective function using inverse design method and the objective function has been the ...

It is notoriously difficult to evaluate L2 prosody objectively, since there is little consensus as to what constitutes a correct prosody for a given utterance. This presentation describes an automatic procedure which consists in comparing a non-native speakers production with 10 instances of the same utterance, taken from the OMProDat database, and read by native speakers. The pitch and relativ...

In this paper we present a new line search method known as the HBFGS method, which uses the search direction of the conjugate gradient method with the quasi-Newton updates. The Broyden-Fletcher-Goldfarb-Shanno (BFGS) update is used as approximation of the Hessian for the methods. The new algorithm is compared with the BFGS method in terms of iteration counts and CPU-time. Our numerical analysis...
