چکیده

This study demonstrates that a commonly used type of factor analysis, principle components analysis, contributes to the amount of error in statistical analysis. In the study, which concerns email use, factor analyses were performed using several different factor analysis methods. The results show that using factors derived via principle components analysis as dependent variables substantially increased the amount of error in regression analyses, and in several cases reduced the amount of explained variance.

Nonlinear Dynamic Modeling and Hysteresis Analysis of Aerospace Hydro - dynamical Control Valves

A new procedure for deriving nonlinear mathematical modeling for a specific class of aerospace hydro - mechanical control valves is presented. The effects of friction on the dynamic behavior of these types of valves along with the experimental verifictions are also given. The modeling approach is based on the combination of the following three tasks: decomposition of the valve into simple speci...

Analysis of Wind Speed Forecasting Error Effects on Automatic Generation Control Performance

The main goal of this paper is to study statistical indices and evaluate AGC indices in power system which has large penetration of the WTGs. Increasing penetration of wind turbine generations, needs to study more about impacts of it on power system frequency control. Frequency control is changed with unbalancing real-time system generation and load . Also wind turbine generations have more flu...

Cross Section Effects on Convergence-Confinement Method in Multi Stage Tunnel Excavation

Dimensionless coefficient () in convergence confinement method shows the relaxation of stress in the wall of the tunnel at different excavation movements. This factor is considered a constant number in previous studies and tunnel geometric characteristics (such as depth, cross-section shape, radius, soil material, etc.) are not included in its determination; however, ignoring these effects can...

Study on effect of detector type in estimating buildup factor of gamma-rays by monte carlo simulation based on variance reduction

This paper presents the study on the effect of detector type in estimating gamma rays buildup factor. In this regard, the flux buildup factors of gamma rays emitted by an isotropic point 60Co source in mean energy 1.253 MeV was evaluated after passing through the Pb, W, Zn, and Ti sample in thickness of 1-5 cm by MCNPX. Four common detector types in simulation of measurement was defined to esti...
