Reconstruction of fingerprint ridge lines is a critical pre-processing step in the identification of poor quality fingerprint images. This paper presents a new fingerprint ridge line reconstruction approach by way of ridge line tracing. In our research, the fingerprint ridge line in a gray scale image is viewed as a track of a ridge segment moving along the ridge. The curve tracing problem is s...

The convergence behavior of (1 +; ){ES is investigated at parabolic ridge, sharp ridge, and at the general case of the ridge functions. The progress rate, the distance to the ridge axis, the success rate, and the success probability are used in the analysis. For the parabolic ridge, we observed in our simulations with large values using (1; ){ES a larger progress rate asymptote than the theoret...

The effects of drip irrigation and different cultivation methods on seedgermination and growth of Puccinellia tenuiflora in saline-sodic soils wereinvestigated in field experiments during 2008-2010 in the Songnen Plain, China.Drip irrigation was applied to waste saline-sodic P. tenuiflora grasslands for bothflat and ridge cultivation methods. Drip irrigation affected the distributions ofelectri...

The purpose of this study was to follow Acree’s 1999 theory and demonstrate that there are significant differences in the loop ridge count of male subjects compared to that of female subjects. This was based on the belief that women tend to have finer ridge detail, therefore more ridges, while men have coarse ridge detail, thereby fewer ridges [1]. This study, in contrast to Acree’s methodology...

Anomalies persist in the foundations of ridge regression as set forth in Hoerl and Kennard (1970) and subsequently. Conventional ridge estimators and their properties do not follow on constraining lengths of solution vectors using LaGrange’s method, as claimed. Estimators so constrained have singular distributions; the proposed solutions are not necessarily minimizing; and heretofore undiscover...

Orthonormal ridgelets are a specialized set of angularly-integrated ridge functions which make up an orthonormal basis for L2(R). In this paper we explore the relationship between orthonormal ridgelets and true ridge functions r(x1 cos θ + x2 sin θ). We derive a formula giving the ridgelet coefficients of a ridge function in terms of the 1-D wavelet coefficients of the ridge profile r(t), and w...

Cotton (Gossypium hirsutum L.) seeds are susceptible to low temperature and excess moisture in soil during seed emergence in years with high rainfall and low temperature in spring. Therefore, a two-year field experiment was carried out to evaluate effects of ridge tillage formed in autumn (RT-I), ridge tillage formed about a month before planting (RT-II) and flat conventional tillage (CT) culti...

In the context of ridge regression, the estimation of ridge (shrinkage) parameter plays an important role in analyzing data. Many efforts have been put to develop skills and methods of computing shrinkage estimators for different full-parametric ridge regression approaches, using eigenvalues. However, the estimation of shrinkage parameter is neglected for semiparametric regression models. The m...
