The paper adapts the Newton-like Extremum-Seeking Control technique to extract the maximum power from photovoltaic panels. This technique uses the gradient and Hessian of the panel characteristic in order to approximate the operating point to its optimum. The paper describes in detail the gradient and Hessian estimations carried out by means of sinusoidal dithering signals. Furthermore, we comp...
In this paper, we consider both local and global convergence of the Newton algorithm to solve nonlinear problems when GMRES is used to invert the Jacobian at each Newton iteration. Under weak assumptions, we give a suucient condition for an inexact solution of GMRES to be a descent direction in order to apply a backtracking technique. Moreover, we extend this result to a nite diierence scheme c...
This paper proposes a technique for load balancing on symmetric multiprocessor systems, where tasks are placed in queues for being processed. Load balancing on processers was run using the RED algorithm and fuzzy system. This system which involves three threads and load balancing was carried out based on these threads. Load balancing operation was carried out in symmetric processers. Load balan...
The process of load balancing increases the performance of cloud based services. Cloud based service provide hardware, software and platform as service. For the balancing of public cloud used two types of approach one is traditional approach and other is dynamic approach. The traditional approach follows the concept of CPU scheduling technique such as round robin and first come first service. T...
Nonlinear Schrödinger equations are usually investigated with the use of variational methods that limited to energy-subcritical dimensions. Here we present approach based on shooting method can give proof existence ground states in critical and supercritical cases. We formulate assumptions system sufficient for this work. As examples, consider Schrödinger-Newton Gross-Pitaevskii harmonic potent...
| In this paper, we present a new implementation of the harmonic balance method which extends its applicability to circuits 2-3 orders of magnitude larger than was previously practical. The results reported here extend our previous work 1] which only considered large circuits operating in a mildly nonlinear regime. The new implementation is based on quadratically convergent Newton methods and i...
In the Bayesian paradigm the marginal probability density function at the observed data vector is the key ingredient needed to compute Bayes factors and posterior probabilities of models and hypotheses. Although Markov chain Monte Carlo methods have simplified many calculations needed for the practical application of Bayesian methods, the problem of evaluating this marginal probability remains ...
Parallel computations comprised of multiple, tightly interwoven phases of computation may require a different approach to dynamic load balancing than single-phase computations. This paper presents a load sharing method based on the view of load as a vector, rather than as a scalar. This approach allows multiphase computations to achieve higher efficiency on large-scale multicomputers than possi...
