With the expansion of wind farm installations in most countries all over the world, the power generation has already significantly influenced on the stability and security of the power grid after gridconnection. Wind power forecasting is an effective method for guarantees stability of the power output from wind farm. This paper proposed an improved GM(1,1) based prediction method, and focuses o...

The main results of this article are asymptotic formulas for the variance of the number of zeros of a Gaussian random polynomial of degree N in an open set U ⊂ C as the degree N → ∞, and more generally for the zeros of random holomorphic sections of high powers of any positive line bundle over any Riemann surface. The formulas were conjectured in special cases by Forrester and Honner. In higher...

78 LLE Review, Volume 82 Introduction Target irradiation uniformity is an important aspect of the direct-drive approach to inertial confinement fusion (ICF),1,2 where the capsule is directly irradiated by a symmetrically arranged cluster of high-intensity, ultraviolet (UV) laser beams. Nonuniformity in laser irradiation seeds the Rayleigh–Taylor hydrodynamic instability, which consequently degr...

The topic of the proposal is a study of the influence of the target illumination by an auxiliary prepulse on a smoothing of spatial non-uniformities in the main laser pulse. In this suggested scheme the prepulse generates an absorption zone near the target surface with non-zero thermal conduction before arrival of the heating pulse. The critical surface position and the size of the absorption z...

conclusions the use of smoothing methods helps us to eliminate non-linear effects but it is more appropriate to use cox proportional hazards model in medical data because of its’ ease of interpretation and capability of modeling both continuous and discrete covariates. also, cox proportional hazards model and smoothing methods analysis identified that age at diagnosis and tumor size were indepe...

As part of test score validity, differential item functioning (DIF) is a quantitative characteristic used to evaluate potential item bias. In applications where a small number of examinees take a test, statistical power of DIF detection methods may be affected. Researchers have proposed modifications to DIF detection methods to account for small focal group examinee sizes for the case when item...

An essential part of any scientific study on any time series analysis depends strongly on availability of reliable data. It is a fact that experimental data records are always contaminated by inaccurate information, not only due to measurement errors but also due to ambiguity of measuring concepts. This occurs especially in fields related to the human science, where unexpected sharp signals are...
