the objective of this study was to investigate the effect of principal components (pc) of the regression coefficients (co)variance matrix on the lactation curve, and on the formation of selection index to modify the curve, based on these pc’s, and as well to estimate additive genetic and phenotypic variances and heritability of the constructed selection index. lactation period of 301 d (5-305) ...

with α 6= 0, and initial condition x(p, 0) = x0(p). This produces a family of curves γt = x(S, t). Here κ is the curvature, and n is the outward-pointing unit normal vector. These equations are particularly natural in that they are isotropic (equivariant under rotations in the plane) and homogeneous (equivariant under dilation of space, if time is also scaled accordingly). The main aim of this ...

Stimulated by recent work by Gregory and Qu, it is shown that the limit of local corner cutting is a continuously differentiable curve in case the corners of the iterates become increasingly flat.

Memory performance by four age groups (30-45 years, 46-60 years, 61-75 years, and 76-90 years) was compared on a multi-trial verbal recall task with 20-minute and 1-day delay free recall and recognition trials. The rate of acquisition across 5 learning trials was similar for all ages except the youngest group whose performance was constrained by a ceiling effect. The level of acquisition achiev...

We study the limiting eigenvalue distribution of n×n banded Toeplitz matrices as n → ∞. From classical results of Schmidt-Spitzer and Hirschman it is known that the eigenvalues accumulate on a special curve in the complex plane and the normalized eigenvalue counting measure converges weakly to a measure on this curve as n → ∞. In this paper, we characterize the limiting measure in terms of an e...

Abstract Certification of external installations on helicopters, for modifications which CS27/29.865 is not applicable, often requires the showing compliance paragraph CS XX.79—limiting height-speed envelope—which might imply, ultimately, a certain degree H–V testing. Due to implications safety during investigation curve, preliminary analytical advisable, understand whether test can be drastica...

Many modern EW systems require low noise receivers capable of withstanding wide input power variations over a multioctave bandwidth. These receivers are necessary to protect sensitive components from RF overdrive or to remove AM modulation from incoming signals. Further, multichannel system designs and proximity to the receiver antenna generate requirements for low power and small package size....
