We present a perturbation method for determining the moment stability of linear ordinary differential equations with parametric forcing by colored noise. In particular, the forcing arises from passing white noise through an nth order filter. We carry out a perturbation analysis based on a small parameter ε that gives the amplitude of the forcing. Our perturbation analysis is based on a ladder o...

We introduce a new method, moment reconstruction, of correcting for measurement error in covariates in regression models. The central idea is similar to regression calibration in that the values of the covariates that are measured with error are replaced by "adjusted" values. In regression calibration the adjusted value is the expectation of the true value conditional on the measured value. In ...

Abstract The catalog of moment tensor solutions, which contains the information on spatial location, origin time and fault mechanism type earthquakes, has been interpreted by researchers based a wealth past knowledge. However, long-term routine analyses have led to accumulation huge amount data in catalog, it is worth considering moving away from artisanal approach. In this study, using dimensi...

Sheet pile walls are flexible retaining structures that used to hold the horizontal soil pressures behind them, especially in situations cause stress changes such as excavation. They divided into two cantilever and externally supported. Cantilever excavations with a maximum depth of 6 meters supported by anchors deeper than this. Some values be calculated design sheet embedment bending moment t...

voltammetric techniques have been considered as important methods among the analytical techniques used for the identification and determination of trace concentrations of many biological molecules such as l-ascorbic acid (aa). l-ascorbic acid is an electro-active molecule, though it is difficult to determine its value directly with a majority of electrodes made of carbon and transition metals, ...

The recently proposed Partition Theory (PT) (J. Phys. Chem. A 2007, 111, 2229), is illustrated on a simple one-dimensional model of a heteronuclear diatomic molecule. It is shown that a sharp definition for the charge of molecular fragments emerges from PT, and that the ensuing population analysis can be used to study how charge redistributes during dissociation and the implications of that red...

stability analysis and g*e interaction of eight commercial monogerm cultivars of sugar beet were evaluated in three years at 11 major sugar beet producing locations karaj, mashhad, miandoab, esfahan, shiraz, kermanshah, kerman, moghan, hamedan, khoy, and brojerd. a randomized complete block design with four replications was used.in each location cultivars  rasoul, shirin, univers, orbis, 7112hy...
