In this article, we develop a simple mathematical GNU Octave/MATLAB code that is easy to modify for the simulation of models governed by fractional-order differential equations, and resolution optimal control problems through Pontryagin's maximum principle (indirect approach control). For purpose, model respiratory syncytial virus (RSV) infection considered. The an improvement one first propose...
In this paper we survey methods to control for regression model error that is correlated within groups or clusters, but is uncorrelated across groups or clusters. Then failure to control for the clustering can lead to understatement of standard errors and overstatement of statistical signi cance, as emphasized most notably in empirical studies by Moulton (1990) and Bertrand, Du o and Mullainath...
This paper considers the computational solution of some first order delay differential equations (DDEs) using a class seventh Hybrid Extended Block Adams Moulton Methods (HEBAMM) without application interpolation techniques in evaluating term. The term was evaluated by valid expression sequence. By matrix inversion techniques, discrete schemes proposed method were obtained through its continuou...
Among Australian fungus-feeding Thysanoptera, five new synonyms are recognised in Horistothrips Morgan, and among leaf-feeding species, three new synonyms are recognised in Teuchothrips Hood and one in Neocecidothrips Moulton. Horistothrips curviseta Girault is transferred to Neocecidothrips as the second species in that genus and its host-plant is identified. Cryptothrips additamentus Karny is...
Assuming that the population remains small, one can truncate at given values of n1 and n2 to yield a finite set of differential equations. For an initial condition, we take the population to be zero, that is, ρ1,1,1,1 = 1 with all other elements of the density matrix set to zero. Eq. A.6 can then be solved numerically (we used the Adams-Moulton-Bashforth procedure) until a steady state is reach...

Seeking to identify thrips species associated to peach and the injuries they cause, plants of Aurora and Tropic Beauty cultivars were weekly monitored, from May to August of 2005, in Holambra II district, in Paranapanema, SP. Flowers and fruits from six plants per hectare were sampled by the hitting technique. Frankliniella occidentalis (Pergande), F. schultzei (Trybom), F. gardenia (Moulton), ...
The classical techniques for determining weights in finite difference formulas were either computationally slow or very limited in their scope (e.g., specialized recursions for centered and staggered approximations, for Adams–Bashforth-, Adams–Moulton-, and BDF-formulas for ODEs, etc.). Two recent algorithms overcome these problems. For equispaced grids, such weights can be found very convenien...
A parallel numerical simulation algorithm is presented for fractionalorder systems involving Caputo-type derivatives, based on the AdamsBashforth-Moulton (ABM) predictor-corrector scheme. The parallel algorithm is implemented using several different approaches: a pure MPI version, a combination of MPI with OpenMP optimization and a memory saving speedup approach. All tests run on a BlueGene/P c...
