Recently, novel learning algorithms such as Support Vector Regression (SVR) and Neural Networks (NN) have received increasing attention in forecasting and time series prediction, offering attractive theoretical properties and successful applications in several real world problem domains. Commonly, time series are composed of the combination of regular and irregular patterns such as trends and c...

The presence of outliers in time series can seriously affect the model specification and parameter estimation. To avoid these adverse effects, it is essential to detect these outliers and remove them from time series. By the Bayesian statistical theory, this article proposes a method for simultaneously detecting the additive outlier (AO) and innovative outlier (IO) in an autoregressive moving-a...

this experiment was carried out at agricultural research station of gorgan during summer 2006 to study the effects of corn and green gram intercropping on forage yield, and weed biomass. the experimental design was rcbd with twelve treatments and four replications. a local green gram and corn single cross 550 were the crops employed. the experimental treatments consisted of sole corn and sole g...

in this paper, a new identification of the lagrange multipliers by means of the sumudu transform, is employed to  btain a quick and accurate solution to the fractional black-scholes equation with the initial condition for a european option pricing problem. undoubtedly this model is the most well known model for pricing financial derivatives. the fractional derivatives is described in caputo sen...

A comparative study on the catalytic activity of a series of Cp*Ir(NHC)Cl2 complexes in several C-O and C-N coupling processes implying hydrogen-borrowing mechanisms has been performed. The compound Cp*Ir(I)Cl2 (I = 1,3-di-n-butylimidazolylidene) showed to be highly effective in the cross coupling reactions of amines and alcohols, providing high yields in the production of unsymmetrical ethers ...

Abstract. Dirichlet density extends global asymptotic density in an additive number system A whose generating series A(x) diverges at its radius of convergence (see [1], p. 50). This note shows that the parallel result holds for a multiplicative number system A, namely if the abcissa of convergence α of the generating series A(x) is finite and A(α) = ∞ then Dirichlet density extends global asym...

The discovery of genes linked with a large array of diseases has been accelerated by genome-wide association studies (GWAS), in which genetic variants in different individuals are examined for relationship with a specified phenotype. Most GWAS analyses require modeling the association between single nucleotide polymorphisms (SNPs) and the outcome of interest as additive, dominant, or recessive....
