One-hundred-ninety-four grass samples, representing eight species, were used to determine the relationships of in vitro forage dry matter, cell wall, hemicellulose and cellulose digestibilities with lignin concentration. Linear regressions indicated that dry matter digestion was inhibited to a lesser degree (P less than .05) by lignin concentration than was cell wall digestion. Results for line...

In 1994 B erenger showed how to construct a perfectly matched absorbing layer for the Maxwell system in rectilinear coordinates. This layer absorbs waves of any wavelength and any frequency without reeection and thus can be used to artiicially terminate the domain of scattering calculations. In this paper we show how to derive and implement the B erenger layer in curvilinear coordinates (in two...

Ранее в наших работах было предложено задачах веерной томографии применять методы перевода пучка веерных лучей набор параллельных лучей. Это достигалось специальной деформацией искомой томограммы на этапе обратного проецирования измеренных и отфильтрованных проекций, с последующей операцией обратной деформации. Деформация для каждого направления наблюдения будет своя, но взаимно-однозначный хар...

The evaluation and automation of tasks involving the manipulation of deformable curvilinear objects, such as threads and cables, requires the real-time estimation of the 3D shapes of these objects from images. This estimation is however extremely challenging due to the small amount of available visual information, the inherent geometric ambiguities, and the large object deformations. We propose...
